The main purpose of this article is to undertake a conceptual investigation of the Berlin Wisdom Paradigm: a psychological project initiated by Paul Baltes and intended to study the complex phenomenon of wisdom. Firstly, in order to provide a wider perspective for the subsequent analyses, a short historical sketch is given. Secondly, a meta-theoretical issue of the degree to which the subject matter of the Baltesian study can be identified with the traditional philosophical wisdom is addressed. The main result (...) yielded by a careful conceptual analysis is that the philosophical and psychological concepts of wisdom, though not entirely the same, are at least parallel. Finally, one of the revealed aspects of the Berlin Wisdom Paradigm, i.e. its relative neglect of the non-cognitive and personal aspects of wisdom is brought to the fore. This deficiency, it is suggested, can be remedied by the application of the virtue ethics' conceptual framework. (shrink)

Amid the ongoing political turmoil, symbolized by the recent violence in Charlottesville, Virginia, books and articles abound today to encourage us to re-read anti-totalitarian classics ‘for our times’. But what do we find in this body of work originally written in response to Nazism and Stalinism? Do we find a democratic consensus forged by a shared anti-totalitarian commitment? I doubt it. Considering the cases of Isaiah Berlin and Hannah Arendt, this article highlights discord beneath what may today appear like (...) a post-war democratic consensus. I argue that the anti-totalitarian literature of the last century encompassed multiple political philosophies, which sometimes differed irreconcilably from each other. (shrink)

The concept of facticity denotes conditions of experience whose necessity is not logical yet whose contingency is not empirical. Although often associated with Heidegger, Fichte coins ‘facticity’ in his Berlin period to refer to the conclusion of Kant’s metaphysical deduction of the categories, which he argues leaves it a contingent matter that we have the conditions of experience that we do. Such rhapsodic or factical conditions, he argues, must follow necessarily, independent of empirical givenness, from the I through a (...) process of ‘genesis.’ I reconstruct Fichte’s argument by tracing the origin of his neologism, presenting his Jena critique of Kant’s rhapsodic appeal to the forms of judgment, and illustrating the Jena period’s continuity with the Berlin period’s genetic method, while noting a methodological shift whereby Fichte directs his critique against his own doctrine of intellectual intuition in order to eliminate its ‘factical terms.’.

Hegel's reading of Hafez as part of his Berlin aesthetics lectures. The jargon of the prosaic world -/- This essay deals with Hegel's reading (Georg Wilhelm Friedrich Hegel, 1770 - 1831) of Hafez' poetry (Moḥammad Schams ad-Din Hafez Schirazi, around 1315 - 1390) during his lectures on the Aesthetics or Philosophy of Art at the University of Berlin (1820/21; 1823; 1826; 1828/29). Hegel's writings, Lectures on Aesthetics, were published from his remains by Heinrich Gustav Hotho (1802 - 1873) (...) in three volumes (1835 - 1838) and in a second edition from 1842 onwards. The posthumously published writings of Hegel are, considering the preserved archive material and the unreliable editing work by Hotho, a thoroughly complex research topic. Therefore, this problem area also forms the starting point of the present analysis of Hegel's reading of Hafez. -/- Within the framework of this essay, Hegel's categories of historical frameworks (Symbolic, Classical, and Romantic Art), especially that of the "Symbolic Art", are examined in his lectures on Aesthetics . This will do in three steps: starting with the current state of research, problematizing of Hegelian concepts in his Lectures on Aesthetics like "oriental Pantheism" or Vorkunst, ("the threshold of art" or "praeambula": T. M. Knox' translation, 1975, part I); extending the discussion by focusing on similarities and differences between Hegel's reading of Goethe (part II) and Hegel's reading of Hafez (part III) in his Berlin Aesthetics Lectures of the 1820's. For this purpose, material from Goethe's literary remains (II), as well as a masterpiece of Dutch painters van Eyck analyzed by Hegel (Ghent Altarpiece) during his lectures (III), will be included in the analysis and explored from an interdisciplinary and intercultural perspective. In doing so, Goethe's “Space of Experience and Horizon of Expectation” (Koselleck) in imitating Arabic script and calligraphy (II) is linked to Hegel's reading of Hafez during his Berlin lectures on aesthetics (III). Thus, a dialogue of cultures unfolds between poetry and philosophy. The main questions are: How does the German philosopher Hegel interpret and receive Hafiz's poetry in the context of German idealist philosophy as a topic of his lectures on aesthetics? What epistemological aspects can be gained from Hegel's reading of Hafez for a cultural studies analysis, especially regarding the history of the ideas? In addition to analyzing the historical aspects, the aim is also to uncover new perspectives in order to look with Hafez and Rumi at Hegel's problem child of ‘history’. Of particular interest are epistemological aspects and problems of reception and translation studies in sense of interdisciplinary and intercultural research (e. g. connected/entangled histories; boundary objects). Interculturality is understood in the context of the present essay as a cross-disciplinary theoretical framework in the sense of entangled histories research work interwoven with communication, aesthetic and cultural techniques approaches or resilience studies in a historical perspective.

This essay considers the theoretical disagreement between Isaiah Berlin and Hannah Arendt on the meaning and value of freedom. Berlin thinks that negative liberty as non-interference is commendable because it is attuned to the implication of value pluralism that man is a choice-making creature and cannot be otherwise. By contrast, the political freedom to act is in Arendt’s view a more fulfilling ideal because it is only in political action that man’s potentiality is actualised, his unique identity manifested (...) and his being-in-the-world-with-others reaffirmed. What lies beneath the two thinkers’ dispute over the most satisfactory meaning of freedom, I argue, is a deeper disagreement over human nature itself. The implication of this analysis for the contemporary debate between pluralist liberals and their agonistic critics is briefly discussed in conclusion. (shrink)

In juxtaposition with the myth and tragedy of Ovid’s Medea, this paper investigates the possibility within the Kantian conception of agency of understanding moral evil as acting against one’s better judgment. It defends the thesis that in Kant self-deception, i. e. the intentional untruthfulness to oneself, provides the fundamental structure for choosing against the moral law. I argue that, as Kant’s thought progresses, self-deception slowly proceeds to become the paradigmatic case of moral evil. This is discussed with regard to two (...) important topics in his later moral philosophy: the doctrine of radical evil and the crucial role of the duty of truthfulness in ethics. The inquiry into Kant’s theory of conscience unfolds both against this theoretical background and in light of its historical roots in the polemic against casuistry and probabilism. This contribution closes with a brief look at the tools Kant implements to counter this tendency to self-deception in moral judgment and particularly at the role casuistry plays within his conception of moral education.

This essay challenges the influential view that Isaiah Berlin and Hannah Arendt played a central role in inaugurating an ‘anti-utopian age’. While the two thinkers certainly did their share to discredit the radical utopian inclination to portray a political blueprint in the abstract, I show that neither was straightforwardly anti-utopian. On the contrary, both thinkers’ writings display a different kind of utopian thinking, consisting in an imaginative and idealized reconstruction of existing polities. Schematically put, Berlin’s utopia was England (...) reconstructed as a quintessential liberal society, whereas Arendt’s utopia was America reconstructed as a quintessential modern free republic. Those two polities differ from each other in important respects, but they share two essential features in common: they are claimed to be exempt from the rise of totalitarianism; and they allegedly give men and women the decent chance to live a fulfilling life. To illustrate Berlin’s and Arendt’s overlapping and yet differing visions, I consider their contrasting responses to the upheaval of 1968 – a possible utopian moment in the late 20th century. While their responses could scarcely be more different, they were informed by their shared desire to imagine an ideal polity in what both regarded as the darkest century in human history. (shrink)

Chapters 17 and 18 of the TTP constitute a textual unit in which Spinoza submits the case of the ancient Hebrew state to close examination. This is not the work of a historian, at least not in any sense that we, twenty-first century readers, would recognize as such. Many of Spinoza’s claims in these chapters are highly speculative, and seem to be poorly backed by historical evidence. Other claims are broad-brush, ahistorical generalizations: for example, in a marginal note, Spinoza refers (...) to his Jewish contemporaries as if they were identical with the ancient Hebrews. Projections from Spinoza’s own experience of his Jewish and Dutch contemporaries are quite common, and the Erastian lesson that Spinoza attempts to draw from his “history” of the ancient Hebrew state is all too conspicuous. Even Spinoza’s philosophical arguments in these two chapters are not uniformly convincing, as I will attempt to show. Yet in spite of all these faults, the two chapters are a masterpiece of their own kind: a case study of the psychological foundations of politics and religion. The work that comes closest in my mind is Freud’s 1939 Der Mann Moses und die monotheistische Religion. The two works are similar not only in terms of their chronological subject matter – the Hebrews of Moses’s time – but also in their attempt to reconstruct the communal psyche of the Hebrews in order to demonstrate their respective social theories about the foundation of civilization. Needless to say, there are numerous differences between the two works, not the least of which are their distinct aims and the very different political contexts in which they were produced. We will return to this comparison with Freud’s Moses and Monotheism toward the end of the essay, but let me first stage the background for our discussion. Chapter 16 of the TTP begins a new section of the book which primarily deals with the relation between religion and the state. In this chapter Spinoza presents an outline of his political theory and his understanding of key notions such as right, power, the state of nature, the social contract, sovereignty, democracy, and justice. The title of chapter 17 announces its aim and focus: “showing that no one can transfer everything to the Supreme Power, and that this is not necessary; on the Hebrew Republic, as it was during the life of Moses, and after his death, before they elected Kings, and on its excellence; and finally, on the causes why the divine Republic [Respublica divina] could perish, and could hardly survive without rebellions” (III/201). The far less ambitious title of eighteenth chapter states that in it “certain Political doctrines are inferred from the Republic and history of the Hebrews” (III/221). Essentially, the two chapters present a surprising, ironic, and penetrating reading of the story of the divine Hebrew Republic, a reading which highlights both how much and how little was achieved by the use of the fantastic political device of attributing divine sanctification to the state and its sovereign.

Heiko Puls’ work Sittliches Bewusstsein und Kategorischer Imperativ in Kants Grundlegung: Ein Kommentar zum dritten Abschnitt, presents an attempt to show that, in the Groundwork of the Metaphysics of Morals, Kant’s argumentation for the objective value of the categorical imperative is almost based upon the same principle as the one presented in the second Critique. More precisely, Puls claims that, like in the Critique of Practical Reason, the Groundwork operates with some kind of fact of reason-theory, which means that our (...) consciousness of the moral law is the ratio cognoscendi of our freedom of will. Accordingly, there is no conclusion from a kind of non-moral consciousness of freedom to the freedom of will and from here to the objective value of the categorical imperative, as many interpreters assume. Due to the ambitiousness of his main thesis and his detailed and subtle way of arguing, Puls’ work represents an important and innovative contribution to recent research on Kant’s Groundwork. Nevertheless, his interpretations sometimes seem to favour analysis of loose philological relationships over closer looks on the contexts of passages. Or he focuses excessively on isolated textual evidences for his readings without appropriately recognising the various other evidences against it. In what follows, I give examples for this criticism.

a book review for Hagen Schulze's "Gibt es überhaupt eine deutsche Geschichte?" done as a homework for university (KIT Institut für Geschichte) Modul Pol.G. I.

La interpretación de la dialéctica hegeliana que el joven Marcuse lleva a cabo en sus escritos tempranos «Sobre el problema de la dialéctica I y II» (1930-1931) y «Ontología de Hegel y teoría de la historicidad» (1932) contrarresta las críticas de Heidegger a la dialéctica de Hegel. La lectura de ambos autores también diverge en su comprensión acerca del estatuto y el alcance del fenómeno de la temporalidad en la filosofía hegeliana. Sin embargo, cuando dilucida el concepto de historicidad (Geschichtlichkeit) (...) en Hegel, Marcuse advierte la tensión existente en su sistema entre el concepto ontológico de «vida» y la idea del «saber absoluto». A partir de su entrada en el Institut für Sozialforschung, el autor berlinés abandonará la tematización del concepto de historicidad —tarea que había ocupado un lugar central en sus primeros escritos— por considerar que dicho concepto, demasiado distorsionado por la tradición ontológico-existencial, es inconciliable con la dialéctica materialista.

Tematem artykułu jest manifest jako gatunek dominujący w awangardzie historycznej (w tym wypadku w dadaizmie), jak i w neoawangardzie austriackiej (akcjonizm wiedeński). Ten ostatni, radykalny ruch sztuki austriackiej lat sześćdziesiątych, dotychczas postrzegany w kategoriach jego osiągnięć w zakresie sztuki performance i body art, analizowany jest przeze mnie w kategoriach literackich na przykładzie manifestu jako środka autoprezentacji, obecnego na skalę masową po raz pierwszy w awangardzie lat dwudziestych. Istotą poruszanego przeze mnie problemu jest kontynuacja tradycji samookreślenia się awangardy w formie manifestu, (...) jak również przemiany, jakie dokonały się w strukturze tekstów tego typu w okresie swoistego renesansu awangardy w latach sześćdziesiątych. Ograniczam się przy tym do zakreślenia jednego z głównych rysów manifestu - jego kontestacyjnej krytyki skierowanej zarówno przeciwko skostniałym formom sztuki, jak i przeciwko państwu i społeczeństwu, narzucającym sztuce granice i sposoby jej oddziaływania. Manifesty dadaistyczne stanowią tutaj tło dla analizy manifestów akcjonistycznych, które, według postawionej przeze mnie tezy, mogą być rozumiane jako radykalna modyfikacja tego gatunku w neoawangardzie, która w swej ostatecznej formie prowadzi do zaniechania manifestu jako przekazu literackiego i do odwołania się do demonstracji celów artystycznych w sposób pozawerbalny - poprzez akcjonizm. W analizie manifestów obu awangard podkreślam krytyczne podejście ich autorów do gatunku jako takiego, jak i do jego korzeni wywodzących się z dziedzin pozaartystycznych (polityka i wojskowość).

This is a revised version of a paper that was originally presented at the first Kant in Asia international conference (on the theme "The Unity of Human Personhood") in May of 2009. It was published as Chapter 64 in Cultivating Personhood: Kant and Asian Philosophy, ed. Stephen R. Palmquist (Berlin: Walter de Gruyter, 2010), pp.811-821. I argue that Kant and the Yijing both employ a form of architectonic reasoning, though their respective understandings of the logical structure of human reasoning (...) are incommensurable. A more thoroughly revised version of the paper was later published in the Journal of Chinese Philosophy and was followed by a series of several other articles arguing that there is a way of arranging the Yijing's 64 hexagrams such that their form is compatible with the form of Kant's table of categories.

I develop a phenomenological account of racialized encounters with works of art and film, wherein the racialized viewer feels cast as perpetually past, coming “too late” to intervene in the meaning of her own representation. This points to the distinctive role that the colonial past plays in mediating and constructing our self-images. I draw on my experience of three exhibitions that take Muslims and/or Arabs as their subject matter and that ostensibly try to interrupt or subvert racialization while reproducing some (...) of its tropes. My examples are the Jean-Joseph Benjamin-Constant exhibition at the Montreal Museum of Fine Arts (2015), the exposition Welten der Muslime at the Ethnologisches Museum in Berlin (2011–2017), and a sculpture by Bob and Roberta Smith at the Leeds City Art Gallery, created in response to the imperial power painting, General Gordon’s Last Stand, that is housed there. My interest is in how artworks contribute to the experience of being racialized in ways that not only amplify the circulation of images but also constitute difficult temporal relations to images. Drawing on Frantz Fanon’s Black Skin, White Masks, I argue that such racialized images are temporally gluey, or stuck, so that we are weighted and bogged down by them. This essay received Honorable Mention from the American Society for Aesthetics Feminist Caucus Committee in the Feminist Research Essay prize in 2020. (shrink)

The famous philosopher Leibniz (1646-1716) was also active in the (cultural) politics of his time. His interest in forming scientific societies never waned and his efforts led to the founding of the Berlin Academy of Sciences. He also played a part in the founding of the Dresden Academy of Science and the St. Petersburg Academy of Science. Though Leibniz's models for the scientific society were the Royal Society and the Royal Science Academy of France, his pansophistic vision of scientific (...) cooperation sometimes took on utopian dimensions. In this paper, I will present Leibniz's ideas of scientific cooperation as a kind of religious activity and discuss his various schemes for the founding of such scientific societies. (shrink)

In this review I consider Gorman's arguments for redescrbiing the history of ethics, from Plato to Isaiah Berlin, as the history of theories of human rights, and for the conclusions that human rights are dependent, that they change over time, and that they may conflict with each other. I disagree with his interpretations of Plato, Hobbes, and Kant, as well as the idea that their moral theories can be converted into theories of human rights without loss, and I argue (...) that his various conclusions about human rights depend upon assumptions - such as that ethics is essentially concerned with motivation, that human nature is changing to the extent that human reason is changing, and that moral reality is inconsistent – that many would reject. Along the way I point out various blunders, such as the claim that that the Hobbesian social contract is a "covenant with the sovereign", and the claim that, according to Kant, "If I act wrongly... I may be acceptably treated as a means.". (shrink)

Value pluralists see themselves as philosophical grown-ups. They profess to face reality as it is and accept resultant pessimism, while criticising their monist rivals for holding on to the naïve idea that the right, the good and the beautiful are ultimately harmonisable with each other. The aim of this essay is to challenge this self-image of value pluralists. Notwithstanding its usefulness as a means of subverting monist dominance, I argue that the self-image has the downside of obscuring various theoretical positions (...) that do not fall into either the pluralist or monist camp. Yet such positions do exist, as shown by my discussion of Albert Camus and Hannah Arendt. Near contemporaries of the pioneering value pluralist Isaiah Berlin, the pair, just like him, sought to be realistic about the lived experiences of political disasters and moral disorientation in the twentieth century. Moreover, they shared with Berlin a keen interest in real-world moral dilemmas, which seemed to them to have made traditional morality obsolete. But the three thinkers’ perspectives on ‘reality’ hardly converged, and neither Camus nor Arendt became a value pluralist as a result of their reflections on moral dilemmas. This, however, by no means indicates the pair’s immaturity. Rather, it shows that there is more than one way of observing fidelity to our actual experience and that value pluralists’ commitment to realism and resultant pessimism is not as uniquely mature as they would have us believe.

Does possessing some human virtues make it impossible for a person to possess other human virtues? Isaiah Berlin and Bernard Williams both answered “yes” to this question, and they argued that to hold otherwise—to accept the harmony of the virtues—required a blinkered and unrealistic view of “what it is to be human.” In this essay, I have two goals: (1) to show how the harmony of the virtues is best interpreted, and what is at stake in affirming or denying (...) it; and (2) to provide a partial defense of the harmony of the virtues. More specifically, I show how the harmony of the virtues can be interpreted and defended within the kind of Aristotelian naturalism developed by philosophers such as Philippa Foot, Rosalind Hursthouse, and Michael Thompson. I argue that far from being an embarrassing liability for Aristotelianism—based in an “archaic metaphysical biology”—the harmony thesis is an interesting and plausible claim about human excellences, supported by a sophisticated account of the representation of life, and fully compatible with a realistic view of our human situation.

The perpetual secretary of the Berlin Academy Johann Heinrich Samuel Formey is best known as a populariser of Christian Wolff’s doctrines. As of Formey’s activity in the Berlin Academy, scholars have mostly emphasized his role in the controversy over monads with Leonhard Euler, while overlooking other interesting contributions Formey presented in the “speculative philosophy” class of the Academy. In this paper, I analyse two articles Formey published in 1747 on the Mémoires de l’Académie de Berlin, namely the (...) Preuves de l’existence de Dieu, ramenées aux notions communes and the Examen de la preuve qu’on tire des fins de la nature, pour établir l’existence de Dieu. In these texts, Formey presents some of Wolff’s methodological and metaphysical ideas, in an implicit dialogue with other members of the Academy – in particular, with the president Pierre-Louis Moreau de Maupertuis – who were also interested in metaphysics and the philosophical method. Formey reworks the Wolffian arguments as to make them more accessible, in order to promote an open confrontation over core philosophical questions. Far from adopting a controversial tone, Formey’s attitude is rather conciliatory: any disagreement, as he thinks, can be easily settled once the true method for philosophizing is made available to everybody.

John Rawls’ gamification of justice leads him – along with many other monist political philosophers, not least Ronald Dworkin – to fail to take politics seriously enough. I begin with why we consider games frivolous and then show how Rawls’ theory of justice is not merely analogous to a game, as he himself seems to claim, but is in fact a kind of game. As such, it is harmful to political practice in two ways: one as regards the citizens who (...) participate directly in it, and the other as regards those who do no more than follow it. Similar harms, I then argue, come from taking politics too seriously, which is the attitude I ascribe to pluralist political philosophers such as Isaiah Berlin, Stuart Hampshire, and Bernard Williams. To them, the plural, incommensurable nature of values means that they cannot be reconciled and so that politics must be a matter of negotiating dirty, and often tragic, compromises. What we need instead, I conclude, is a third way, one that is neither monist nor pluralist but in-between the two extremes. (shrink)

How surprising is the insight, that being equals I in the 15th lecture of the Doctrine of Science 1804/II? It might have been indeed an unexpected turn for his contemporaries in Berlin listening to Fichte for the first time, but should it be surprising for us, having at least since 2012 (the year the last volume of [Gesamtausgabe] appeared) access to all his published and unpublished works? I want to propose a way of reading Fichte, which bypasses two popular (...) and contradictory interpretations of his philosophy in the post-Jena period: (a) the Absolute is the new first principle (hence the I is just a shadow of the much higher being) and (b) his system basically remains unchanged (hence the being is nothing more than the I). At first, I analyze the functions of later Fichte’s improved version of the Kantian and Reinholdian abstract subject-object-symbolism and assign specific content to it. This will shed light on the structure and the first principle of the Doctrine of Science 1804/II. In the second section I give reasons why Fichte calls both God and I “absolute” and “pure being” and explain their relation to each other referring to a thought experiment sometimes used by Kant—an analogy between the divine and human (pure) reason. The analogical thinking of this kind remains within the borders of transcendental philosophy as long as it is used only for certain didactic purposes. (shrink)

In this book I show that science suffers from a damaging but rarely noticed methodological disease, which I call rationalistic neurosis. It is not just the natural sciences which suffer from this condition. The contagion has spread to the social sciences, to philosophy, to the humanities more generally, and to education. The whole academic enterprise, indeed, suffers from versions of the disease. It has extraordinarily damaging long-term consequences. For it has the effect of preventing us from developing traditions and institutions (...) of learning rationally devoted to helping us learn how to make progress towards a wiser, more civilized world. On our fragile earth, overcrowded, fraught with injustice, inequality and conflict, menaced by unprecedented and terrifying technological and industrial means for change and destruction, we urgently need to acquire a little more wisdom and civilization if we are to avoid repeating horrors of the kind suffered by so many during the 20th century (and already suffered by many in the first few years of the 21st century). We can ill afford to have in our hands instruments of learning botched and bungled from the standpoint of helping us learn how to live more wisely. It may seem scarcely credible that something as important as our institutions of learning can suffer from wholesale, structural defects. Why has this not been noticed before? Why have not armies of scientists and scholars appreciated the point and, long ago, put the matter right? The answer will emerge as my argument unfolds. I will show that one of the most damaging features of rationalistic neurosis is that it has built-in methodological and institutional mechanisms which effectively conceal that anything is wrong. But there is also an immediately obvious reason: specialization, and the resulting fragmentation of academia, has resulted in a situation in which hardly anyone takes responsibility for the overall ideals, the overall aims and methods, of academic inquiry. Academics, these days, are specialists, furiously trying to keep abreast of developments in their own specialist fields. They have no time, and no inducement, to lift their eyes from their particular disciplines, and look at the whole endeavour. Science has long been under attack, at least since the Romantic movement. Blake objected to “Single vision & Newton’s sleep” and declared that “Art is the Tree of Life... Science is the Tree of Death”. Keats lamented that science will “clip an Angel’s wings” and “unweave a rainbow”. Whereas the Enlightenment had valued science and reason as tools for the liberation of humanity, Romanticism found science and reason oppressive and destructive, and instead valued art, imagination, inspiration, individual genius, emotional and motivational honesty rather than careful attention to objective fact. Much subsequent opposition to science stems from, or echoes, the Romantic opposition of Blake, Wordsworth, Keats and many others. There is the movement Isaiah Berlin has described as the “Counter-Enlightenment” (Berlin, 1979, ch. 1). There is existentialism, with its denunciation of the tyranny of reason, its passionate affirmation of the value and centrality of irrationality in human life, from Dostoevsky, Kierkegaard and Nietzsche to Heidegger and Sartre (see, for example, Barrett, 1962). There is the attack on Enlightenment ideals concerning science and reason undertaken by the Frankfurt school, by postmodernists and others, from Horkheimer and Adorno to Lyotard, Foucault, Habermas, Derrida, MacIntyre and Rorty (see Gascardi, 1999). The soul-destroying consequences of valuing science and reason too highly is a persistent theme in literature: it is to be found in the works of writers such as D.H. Lawrence, Doris Lessing, Max Frisch, Y. Zamyatin. There is persistent opposition to modern science and technology, and to scientific rationality, often associated with the Romantic wing of the green movement, and given expression in such popular books as Marcuse’s One Dimensional Man, Roszak’s Where the Wasteland Ends, Berman’s The Reenchantment of the World and Appleyard’s Understanding the Present. There is the feminist critique of science and conceptions of science: see, for example, Fox Keller (1984) and Harding (1986). And there are the corrosive implications of the so-called “strong programme” in the sociology of knowledge, and of the work of social constructivist historians of science, which depict scientific knowledge as a belief system alongside many other such conflicting systems, having no more right to claim to constitute knowledge of the truth than these rivals, the scientific view of the world being no more than an elaborate myth, a social construct (see Barnes and Bloor, 1981; Bloor, 1991; Barnes, Bloor and Henry, 1996; Shapin and Schaffer, 1985; Shapin, 1994; Pickering, 1984; Latour, 1987). This latter literature has provoked a counter-attack by scientists, historians and philosophers of science seeking to defend science and traditional conceptions of scientific rationality: see Gross and Levitt (1994), Gross, Levitt and Lewis (1996), and Koertge (1998). This debate between critics and defenders of science came abruptly to public attention with the publication of Alan Sokal’s brilliant hoax article ‘Transgressing the boundaries’ in a special issue of the cultural studies journal Social Text in 1996 entitled Science Wars: see Sokal and Bricmont (1998). What does this book have to contribute, given the above avalanche of criticism of science? The criticisms of science developed in this book are diametrically opposed to the above, in so far as the above criticisms oppose scientific rationality, seek to diminish or restrict its influence, or hold that it is unattainable. My central point is that we suffer, not from too much scientific rationality, but from not enough. What is generally taken to constitute scientific rationality is actually nothing of the kind. It is rationalistic neurosis, a characteristic, influential and damaging kind of irrationality masquerading as rationality. Science is damaged by being trapped within a widely upheld but severely defective philosophy of science; free science from this defective philosophy, provide it with a more intellectually rigorous philosophy, and it will flourish in both intellectual and humanitarian terms. And more generally, as we shall see, academic inquiry as a whole is damaged by being trapped within an intellectually defective philosophy of inquiry; free it from this defective philosophy, from its rationalistic neurosis, and it will flourish in intellectual and human terms. It is not reason that is damaging, but defective pretensions to reason — rationalistic neurosis —masquerading as reason. Thus what I seek to do here is the exact opposite of what all those who oppose science and scientific rationality do. I shall argue that Reason, the authentic article, arrived at by generalizing the progress-achieving methods of science, can have profoundly liberating and enriching consequences for all worthwhile, problematic aspects of life, and thus deserves to enter into every aspect of life. The bare bones of the argument of this book can be stated quite simply like this. Science cannot proceed without making the substantial metaphysical assumption that the universe is physically comprehensible (to some extent at least). But this conflicts with the orthodox view that in science everything is assessed impartially with respect to evidence, nothing being permanently assumed independently of evidence. So the metaphysical assumption of comprehensibility is repressed. Science pretends that no such assumption is made. But this damages science. For the assumption is substantial, influential and highly problematic. It needs to be made explicit within science so that it can be critically scrutinized, so that alternatives can be developed and considered. Pretending the assumption is not being made undermines the intellectual rigour of science, its intellectual value and success. And it does not stop there. For science also makes value assumptions. Quite properly, science is concerned to discover that which is of value. New factual knowledge devoid of all value (whether intellectual or practical) does not contribute to science. But the orthodox view of science holds that values have no place within science. As in the case of metaphysics, here too, science pretends that values have no role to play within the intellectual domain of science. And this damages science. For values are, if anything, even more influential and problematic than metaphysics (in influencing the direction of research). Here too, values need to be made explicit within science so that they can be scrutinized, so that alternatives can be developed and assessed. Pretending that values play no role within the intellectual domain damages science; both the intellectual and the practical aspects of science are adversely affected. Science fails to pursue those avenues of research that lie in the best interests of humanity. And it goes further. Science is pursued in a social, cultural, economic and political context. It is a part of various social, economic and political projects which seek to achieve diverse human objectives. But the idea that science is an integral part of humanitarian or political enterprises with political ends clashes, once again, with the official view of science that the aim of science is to improve factual knowledge. The political objectives of science are repressed. And, once again, this damages science. For, of course, the political objectives of science, like all our political objectives, are profoundly problematic. These need to be made explicit so that they can be scrutinized, so that alternatives can be developed and considered. The pretence that science does not have this political dimension once again undermines the intellectual rigour of science, and its human value. It lays science open to becoming a part of economic, corporate and political enterprises that are not in the best interests of humanity. The upshot of the line of argument just indicated is that we need to bring about a revolution in the aims and methods of science, and of academic inquiry more generally. Natural science needs to change; its relationship with the rest of academic inquiry, with social inquiry and the humanities, needs to change; and most importantly and dramatically, academic inquiry as a whole needs to change. The basic task of the academic enterprise needs to become to help humanity learn how to tackle its problems of living in more cooperatively rational ways than at present. We need to put the intellectual tasks of articulating our problems of living, and proposing and critically assessing possible solutions, possible and actual actions, at the heart of academic inquiry. The basic task needs to be to help humanity learn a bit more wisdom – wisdom being the capacity to realize what is of value in life, for oneself and others, wisdom including knowledge and technological know-how, but much else besides. Natural science, despite its flaws, has massively increased our knowledge and technological know-how. This in turn has led to a massive and sometimes terrifying increase in our power to act. Often this unprecedented power to act is used for human good, as in medicine or agriculture. But it is also used to cause harm, whether unintentionally (initially at least) as when industrialization and modern agriculture lead to global warming, destruction of natural habitats and rapid extinction of species, or intentionally, as when the technology of war is used by governments and terrorists to maim and kill. Before the advent of modern science, when we lacked the means to do too much damage to ourselves and the planet, lack of wisdom did not matter too much. Now, with our unprecedented powers to act, bequeathed to us by science, lack of wisdom has become a menace. This is the crisis behind all the other current global crises: science without wisdom. In these circumstances, to continue to pursue knowledge and technological know-how dissociated from a more fundamental quest for wisdom can only deepen the crisis. As a matter of urgency, we need to free science and academia of their neuroses; we need to bring about a revolution in the academic enterprise so that the basic aim becomes to promote wisdom by intellectual and educational means. At present science and the humanities betray both reason and humanity. The argument of this book, which I have just summarized, begins with a discussion of the philosophical and methodological problems that beset theoretical physics. At once, many of those who are concerned about moral, political and environmental issues that plague our world today, will feel impatient. What have the methodological problems of theoretical physics to do with third world poverty, war and the threat of war, pollution, extinction of species, the menace of conventional, chemical, biological and nuclear armaments? I can only plead with such a reader: patience. The root cause of the sickness of our times does indeed lie, I claim, with a methodological sickness of natural science or, even more specifically, of physical science. What makes the modern world so utterly different from all previous ages is our possession of modern science and technology. This is the instrument that has changed the conditions of human life almost beyond all recognition, and put unprecedented, and sometimes terrifying, powers into our hands. One should not dismiss out of hand the suggestion that a part of our problem may lie with this instrument, this engine, of rapid change. We see, here, too, the way in which intellectual specialization, referred to above, has effectively concealed from view the nature and extent of the problem that confronts us. The argument that I shall develop in what follows begins with physics, with problems concerning the aims and methods of physics. But it then leaps to social science, to philosophy, to the humanities, to education, to psychotherapy, and to politics: in the end there is scarcely an aspect of modern life that is not touched and, potentially, affected by the argument. How many academic experts are prepared to follow, to take seriously, an argument that ranges so recklessly across such a wide range of academic disciplines? How many non-academic non-experts? But just this is what the argument and message of this book requires. I hope that the reader will endure with patience the somewhat esoteric discussion concerning the aims and methods of physics pursued in chapter one. This may not seem to have anything much to do with the urgent problems of our times, but it does. This is in part how the intellectual disaster I seek to expose in this book conceals itself from view: it buries itself in the obscure, recondite field of the philosophy of physics. Those who devote their lives to the philosophy of physics are, by and large, too myopic to see how their specialized field of study has anything to do with the great and dreadful humanitarian problems and disasters of our age; and those who are above all concerned with these humanitarian disasters have no time at all for abstruse issues concerning the aims and methods of physics. And so the connection is never made. As it happens, the methodological neurosis of physics, with which we begin in chapter one, is actually a quite simple matter to grasp. It does not require any real knowledge of physics to understand. Indeed, physicists and philosophers of physics are much more likely to find the argument difficult to follow than are non-experts. We non-scientists can stand back and see the whole wood; scientists, trained to think in terms of the current orthodox conception of science, trapped in the thickets of research, will find this much harder to do. In an attempt to take this peculiar circumstance into account, I have arranged the exposition as follows. In chapter one I give a simple exposition of the case for declaring natural science to suffer from what I call "rationalistic neurosis"; this avoids all technicalities, and goes straight to the heart of the matter. In the appendix I tackle a host of more technical objections that may be made to the elementary argument of chapter one. So, those experts in the fields of the philosophy of physics and philosophy of science who find the argument of chapter one naïve and unconvincing, should consult the appendix before tossing the book away in disgust. I write in the hope that there will be a few who will not dismiss out of hand the suggestion that the question of how we are to go about learning how to live in wiser and more civilized ways might have something to learn from scientific learning, and will take the trouble to pursue the line of argument traced out in this book. I write in the hope that these few will grasp just how desperate our situation is, how urgent the need to change the status quo, and will do everything in their power to alert others to the need to heal the methodological sickness from which our institutions and traditions of learning at present suffer. To begin with, we need a campaigning organization, modelled perhaps on "Friends of the Earth", which might be called something like "Friends of Wisdom". (shrink)

Ethnobiology has a long tradition of metaphysical debates about the “naturalness,” “objectivity”, “reality”, and “universality” of classifications. Especially the work of Brent Berlin has been influential in developing a “convergence metaphysics” that explains cross-cultural similarities of knowledge systems through shared recognition of objective discontinuities in nature. Despite its influence on the development of the field, convergence metaphysics has largely fallen out of favor as contemporary ethnobiologists tend to emphasize the locality and diversity of classificatory practices. The aim of this (...) article is twofold: First, I provide a historical account of the rise and fall of convergence metaphysics in ethnobiology. I show how convergence metaphysics emerged as an innovative theoretical program in the wake of the “cognitive revolution” and the “modern evolutionary synthesis” but failed to incorporate both theoretical insights and political concerns that gained prominence in the 1980s and 1990s. Second, I develop a positive proposal of how to engage with metaphysical issues in ethnobiology. By integrating traditional research on convergence of classifications with more nuanced accounts of distinctly local categories, a revamped metaphysics of ethnobiological classification can make substantial contributions to debates about ontological difference in anthropology and about the relation between applied and theoretical ethnobiology.

If a problem is the collision between a system and a fact, Spinozism and German idealism’s greatest problem is the corpse. Life’s end is problematic for the denial of death’s qualitative difference from life and the affirmation of nature’s infinite purposiveness. In particular, German idealism exemplifies immortalism – the view that life is the unconditioned condition of all experience, including death. If idealism cannot explain the corpse, death is not grounded on life, which invites mortalism – the view that death (...) is the unconditioned condition of experience. In “Philosophical Letters,” Schelling critiques idealism, arguing that death symbolizes the regulative ideal of a philosophical system’s derivation, our striving for which unifies our rational activity. I interpret Schelling’s critique as explaining how death puts philosophy into question, an idea he develops in the Freedom essay and Berlin lectures. Death is not a problem to be solved by a system, but represents philosophy’s highest yet unrealizable end. (shrink)

Political philosophy has seen vibrant debate over the connection, if any, between liberalism and pluralism. Some philosophers, following Isaiah Berlin, reckon a close connection between the two concepts. Others--most notably John Gray--believe that liberalism and pluralism are incompatible. In this essay, I argue that the puzzle can be solved by distinguishing the responsibilities of liberal states to their peoples from the responsibilities of liberal states to other states. There is an entailment from pluralism to liberalism, and it in turn (...) implies that while liberal states must tolerate "illiberal" lifestyles within their borders, liberal states must not tolerate illiberal states. The fact of liberal intolerance, however, does not justify unreasonably aggressive intervention by liberal states, nor does it mean that illiberal states deserve to be punished. (shrink)

This paper reconstructs the American reception of logical positivism in the early 1930s. I argue that Moritz Schlick (who had visiting positions at Stanford and Berkeley between 1929 and 1932) and Herbert Feigl (who visited Harvard in the 1930-31 academic year) played a crucial role in promoting the *Wissenschaftliche Weltauffassung*, years before members of the Vienna Circle, the Berlin Group, and the Lvov-Warsaw school would seek refuge in the United States. Building on archive material from the Wiener Kreis Archiv, (...) the Harvard University Archives, and the Herbert Feigl Papers, as well as a large number of publications in American philosophy journals from the early 1930s, I reconstruct the subtle transformation of the American philosophical landscape in the years immediately preceding the European exodus. I argue that (1) American philosophical discussions about meaning and significance and (2) internal dynamics in the Vienna Circle between 1929 and 1931 significantly impacted the way in which US philosophers came to perceive logical positivism.

Criteria of acceptability for mathematical proofs are field-dependent. In topology, though not in most other domains, it is sometimes acceptable to appeal to visual intuition to support inferential steps. In previous work :829–842, 2014; Lolli, Panza, Venturi From logic to practice, Springer, Berlin, 2015; Larvor Mathematical cultures, Springer, Berlin, 2016) my co-author and I aimed at spelling out how topological proofs work on their own terms, without appealing to formal proofs which might be associated with them. In this (...) article, I address two criticisms that have been raised in Tatton-Brown against our approach: that it leads to a form of relativism according to which validity is equated with social agreement and that it implies an antiformalizability thesis according to which it is not the case that all rigorous mathematical proofs can be formalized. I reject both criticisms and suggest that our previous case studies provide insight into the plausibility of two related but quite different theses. (shrink)

This article seeks to justify the claim that Thomas Aquinas proposed a concept of natural law which is immune to the argument against the recognition of an objective grounding of the good formulated by a well-known representative of the liberal tradition, Isaiah Berlin, in his famous essay “Two Concepts of Freedom.” I argue that Aquinas’s concept of freedom takes into account the very same values and goals that Berlin set out to defend when he composed his critique of (...) natural law. In particular, the article suggests that Aquinas recognizes freedom as a greater perfection of man than rationality, and that this freedom is realized, among other things, through the co-construction of the good that gives a goal and a shape to human action and to the whole of a person’s life. I argue that the co-construction of such a good involves the co-construction of natural law in the strict sense of the term. Indeed, the content of natural law can be understood as a set of goods which are goals that inform human action. From a human perspective, natural law is not a pre-existing recipe which has merely to be “read.” Defining the concrete content of natural law is an ongoing process. The process of defining natural law’s content takes humanly knowable, objective elements into account, and so draws on knowledge. Yet free choice also plays an important part in this process. When speaking of the process of defining the content of natural law, therefore, and in determining what here-and-now is to be done, it is reasonable to describe man as a creator of the natural law, or as a legislator, just as the members of a parliament are the creators of civil law — bearing in mind that only a just law is truly law and therefore the creation of both civil and natural law reaches only as far is the scope of just actions directed by these laws. From the perspective of human action, we may speak of each person’s free choice to establish a given good as the end of a specific act, and in so doing to declare that action proper under natural law in the strict sense of the term (which differs from the rules of natural law). An appreciation of what is particular and individual (particulare et individuum), and an appreciation of free choice that goes hand-in-hand with this, is deeply embedded in Thomas’s system of thought. Particularity and individuality has its basis in an especially excellent way of human existence. (shrink)

Two competing models of metaaxiological justification of politics are analyzed. Politics is understood broadly, as actions which aim at organizing social life. I will be, first of all, interested in law making activities. When I talk about metaaxiological justification I think not so much about determinations of what is good, but about determinations refering to the way the good is founded, in short: determinations which answer the question why something is good. In the first model, which is described here as (...) objectivistic, it is assumed that determining that which is good is a matter of cognition; in the second model, which could be described here as voluntaristic or excedingly liberal, it is assumed that determining good is not a matter of cognition but of will – something is good because it is wanted. In the latter model, the cognoscibility of good is rejected and therefore the objective criteria for evaluation of which ‘will’ is better and which is worse are rejected. As a consequence, negative freedom becomes the fundamental value of social order and the basic requirement is that of maximizing the sphere of individual’s free actions, the sphere which is free from interference of other individuals or institutions. I am going to argue that none of these models is acceptable as a basis of oragnizing social life, and at least because of one reason. Each of them leads to a certain version of totalitarianism. In the conclusion I am going to present a mixed model, which, in my opinion, reflexes well the practice of democratic states. Analysis of these three models allows, first of all, to identify more clearly some of the problems appearing in making law, including procedural questions. By pointing at the interdependence of the foundations of good and law making procedures it is argued that the choice of the concept of good (a metaaxiological choice) is primary to the choice of law making procedures.

In Crowder’s reformulation of Berlin’s argument, not only does value pluralism provide support for liberalism, it actually suggests a version of liberalism that promotes the public use of personal autonomy. For Crowder, personal autonomy is a necessary element given value pluralism as it allows the individual to choose between a plurality of incommensurable options. In order to advance personal autonomy, Crowder advocates a robust account of freedom of exit coupled with a form of autonomy-facilitating education. To this effect Crowder (...) posits that it is acceptable to intervene in the lives of non-liberals in order to promote individual autonomy as a public ideal. However, I argue that despite the positive implications that a pro-autonomy account of liberalism may have for both the individual and the state, it will limit range of acceptable values within the liberal state and thus undermine certain aspects of value pluralism.

Human life in contemporary society is extremely complex and there are various external factors that directly affect the realization in the individual ends. In this work I analyze the effects of the global market economy, manifested by a mode of production and distribution of goods and services in the form of a global network of economic relations, which involve people, transnational corporations and political and social institutions in moral sphere of people, affecting their choices and the realization of these choices. (...) Individual freedom can be understand as a freedom to realize our choices in the environment of a global economic market, but it is still problematic in the sense that the choices of goods and services available in this market do not reflect individual choices, but a set of preferences standardized according to the market itself. In this paper I will reflect about the individual freedom in economic globalization pointing from the debate between Pettit and Berlin that social freedom advocated by Republican Petit can be satisfactory for a start.

Hegel’s dispute with Schleiermacher in Berlin had as its premise his reception of Schleiermacher’s Reden über die Religion. My intention is to clarify the history of this reception by arguing that Hegel’s Frankfurt early writings already contain clues as to his reading of Schleiermacher’s work. Differently from previous interpretations, however, I will not support the hypothesis that, during his Frankfurt period, Hegel was influenced by Schleiermacher’s foundations of religion. My contention is that, from the very beginning, Hegel opposed Schleiermacher’s (...) concepts of positivity and polemics as specific features of the Christian religion. This view is confirmed if we analyze the works that Hegel wrote in the Jena period, such as Differenz des Fichte’schen und Schelling’schen Systems der Philosophie, Glauben und Wissen and Phänomenologie des Geistes. My aim is to demonstrate that these works typify Schleiermacher’s approach to the Christian religion, and in so doing, to confute the idea that Hegel’s view on the above-mentioned approach changed over the years. A final aspect that I consider is the enduring nature of Hegel’s conception of the significance of the Reden – an aspect that emerges on analyzing some crucial sentences in the Grundlinien der Philosophie des Rechts.

In a morally diverse society, moral agents inevitably run up against intractable disagreements. Civility functions as a valuable constraint on the sort of behaviors which moral agents might deploy in defense of their deeply held moral convictions and generally requires tolerance of other views and political liberalism, as does pluralism. However, most visions of civility are exceptionless: they require civil behavior regardless of how strong the disagreement is between two members of the same society. This seems an excellent idea when (...) those required to do the tolerating might otherwise smash us. However, the demands of civility are universal and fall upon everyone, including ourselves. They may seem to require us to tolerate the intolerable, leading us not into pluralism but rather into functional relativism, and also require the powerless to moderate their demands for redress. They also place moral agents in a very difficult position with respect to realizing our deeply held moral values. Isaiah Berlin’s pluralism, by contrast, allows us to violate tolerance when we come up against values which, put into practice, are incompatible with a form of life we can tolerate. Despite the many fronts on which civility and pluralism align, they are also pitted against each other. Only a qualified (not exceptionless) civility based in respect for persons can cohere with pluralism and thus resolve the double bind in which the moral agent seemed to be placed by exceptionless civility. I develop a rule for Accepted Exceptions that helps to explain how moral agents can be civil, value pluralism, demand redress, and maintain their own deeply held moral commitments. (shrink)

Wie jedes Krankenhaus hat Charité ihre Geschichte, die mit dem Erlaß des preußischen Königs Friedrich I. vom 14. November 1709 zur Gründung von Lazareth-Häusern anfing, um der Ausbreitung der Pest entgegenzuwirken, wozu es allerdings in Berlin nie gekommen ist. Am 9. Januar 1727 verfügte König Friedrich Wilhelm I. die Umwandlung des vor dem Spandowischen Tor errichteten Lazareth in ein Hospital und nannte es „das Haus die Charité“ nach dem Vorbild von Hôpital de la Charité in Paris. -/- Das Wort (...) und der Begriff Charité ist wesentlich älter als das Krankenhaus. Das Französische charité ist äquivalent dem Englischen charity und dem Deutschen Barmherzigkeit, während ihre Ursprünge im Griechischen zu finden sind: χάρις bedeutet Gnade, Gunst, χαριτόω Gnade oder Gunst zeigen oder empfangen, favorisieren oder favorisiert werden, gnädig oder begnadet sein. Das Krankenhaus ist ein Ort der Gnade, welche den Kranken und Bedürftigen zusteht aufgrund allgemeiner Verpflichtung, seinen Nächsten so zu lieben wie sich selbst. Die Gunst und die Gnade zu erweisen heißt auch, sich zu erbarmen und mitleidig sein, eigenes Herz für fremdes Leid zu offnen. -/- Seit ihrer Gründung weichte Charité von diesem Grundgedanke mehrmals ab, was bisher in ihrer Geschichtsschreibung mehr oder weniger wahrheitsgetreu festgehalten wurde. Dieser Tradition des Festhaltens und der Wiedergabe der Wahrheit bin ich verpflichtet, weil offizielle Geschichtsschreibung erneut beginnt, von der Realität abzuweichen und die Tatsachen zu leugnen, die sowohl unzweifelhaft sind als auch unzweifelhaft würdig sind, erzählt zu werden, weil es dabei um die Frage des Auftrags der Charité geht. -/- Charité wurde gegründet, um das Unheil abzuwenden, dennoch war ihre Geschichte keine Heilsgeschichte, wie ich bereits feststellte. Das Unheil setzte sich im 21. Jahrhundert fort, was ich zu unterbinden suche. Einziges Heilmittel dagegen ist die Wahrheit, daran besteht kein Zweifel, und der Weg, um die Wahrheit zu erkennen, ist die Barmherzigkeit. (shrink)

What is the exact relationship between analytic philosophy and philosophy of science? In this paper, I will address this question from the perspective of research traditions, with the help of recent histor- ical studies on analytic philosophy.

However, by taking seriously their connection to the development of analytic philosophy and philosophy of science as research traditions, I believe, (...) the understanding of our own tradition may be improved.

According to a widely shared view, a radical change took place in the role of intersubjectivity in Hegel's philosophy somewhere between Jena and Berlin. For instance, Jürgen Habermas's judgement is that whereas in the Jena writings – in the JenaRealphilosophien, and perhaps still in the 1807Phenomenology of Spirit– Hegel conceived of intersubjectivity as an essential element in the constitution of subjectivity and of objectivity, in Berlin Hegel's intersubjectivist conception was replaced by a metaphysics of the absolute I or (...) absolute self-consciousness, in which intersubjectivity no longer plays any important constitutive role.Perhaps it is due to something like this view having been mostly taken for granted even among Hegel-specialists that scholarly literature on intersubjectivity in Hegel's late Encyclopaedic system is indeed very scarce. Robert R. Williams'Hegel's Ethics of Recognitionargues convincingly that the theme of intersubjective recognition can be seen as a central thread running through the whole of Hegel's Encyclopaedic philosophy ofobjectivespirit. But very little has so far been written on the theme of intersubjectivity or intersubjective recognition in Hegel's Encyclopaedic philosophy of subjective spirit. My thesis in what follows is that intersubjectivity or intersubjective mediation in recognition can and should in fact be seen as an essential constituent also of subjective spirit as Hegel conceptualises it in the 1830 Encyclopaedia.

Bernard Williams articulated his later political philosophy notably in response to Ronald Dworkin, who, striving for coherence or integrity among our political concepts, sought to immunize the concepts of liberty and equality against conflict. Williams, doubtful that we either could or should eliminate the conflict, resisted the pursuit of conceptual integrity. Here, I reconstruct this Dworkin–Williams debate with an eye to drawing out ideas of ongoing philosophical and political importance. The debate not only exemplifies Williams's political realism and its connection (...) to his critique of the morality system. It also illustrates the virtues and hazards of contemporary efforts to ameliorate or engineer our concepts; it indicates what political philosophy might look to in appraising political concepts; it adverts to the different needs these concepts have to meet if they are to sustain a politics of pluralism, deal with polarization, and secure the consent of those who end up on the losing side of political decisions; and it presents us with two starkly contrasting conceptions of politics itself, of the place of political values within it, and of our prospects of reducing the uncomfortably conflictual character of those values through philosophy.

The legacy of George W. Bush will probably be associated with the President’s infallibly certain style of visionary leadership and his specific vision of a ‘Freedom Agenda’. According to this vision, the United States must spread democracy to all people who desire liberty and vanquish those tyrants and terrorists who despise it. Freedom is universally valued, and the United States is everywhere perceived as freedom’s protector and purveyor. So, the mission of the Freedom Agenda is to guard existing freedoms as (...) well as spread the democratic political system to those countries lacking comparable freedoms. Recent analyses of the Bush Freedom Agenda examine its roots in realist foreign policy and neoconservative political thought. In this paper, I take a different approach, connecting the Freedom Agenda to the ideas of two philosophers: (i) Isaiah Berlin’s notion of positive-negative liberty and (ii) John Dewey’s concept of freedom as a function of culture. My central claim is that when compared with the ideas of Berlin and Dewey, the Freedom Agenda is a faulty construct, both conceptually and practically, for understanding America’s role in global affairs. The Freedom Agenda proves to be neither conservative nor universal. Nevertheless, it constitutes an essential element of George W. Bush’s legacy, a vision of American purpose in a threatening and divisive world. (shrink)

In his early and unpublished essay on Schiller’s trilogy Wallenstein, Hegel criticizes the plays’ denouement as “horrific” and “appalling” and for depicting the triumph of death over life. Why was the young Hegel’s response to Wallenstein so negative? To answer this question, I first offer an analysis of Wallenstein in terms of Hegel’s mature theory of modern tragedy. I argue that Schiller’s portrayal of Wallenstein’s character and death indeed render the play a particularly dark and unredemptive example of modern tragedy (...) as Hegel understands it. I suggest, however, that Hegel’s early objections are primarily motivated by his philosophy of history rather than by his theory of tragedy. Hegel accurately sensed the loss of faith in historical progress that Schiller experienced in the wake of the French Revolution; in essays written shortly before Wallenstein appeared, Schiller associates the tragic sublime with humans’ ability to act in the face of the meaninglessness of history. In his essay “The German Constitution,” composed during the same period as his Wallenstein review, Hegel instead formulates his familiar exhortation that we see history as meaningful. Hegel’s objection to Wallenstein’s darkness, then, is primarily an objection to the vision of history it portrays. Against the background of Peter Stein’s 2007 Berlin production of Wallenstein, I suggest that Wallenstein’s lasting appeal lies in its ability to allow audiences to experience the sublime as Schiller intended: as an assertion of our agency despite the cycles of history we so little control.

The aim of this essay is to analyze the concept of ecstasy in F. W. J. Schelling's Erlangen Lectures. In particular, I intend to show how it constitutes a significant evolution with regard to the model of reminiscence and in particular that of Mitwissenschaft, as presented in the Weltalter. The essay focuses on three aspects of the notion of ecstasy: 1) its relation to temporality, 2) its relation to interiority, and 3) its noetic value and its moral dimension. In conclusion, (...) I will show how in Erlangen a movement of progressive de-historicization and de-theosophicization of ecstasy began, culminating in the Berliner Einleitung of 1842/43. (shrink)

This article examines Hegel’s aesthetic judgment of the German romantic painter Caspar David Friedrich, which only first came to light in 1995 with the publication of the separate edition of the Ascheberg transcript of Hegel’s first lecture course on aesthetics, held at the University of Berlin in the winter semester of 1820/21. Firstly, before interpreting Hegel's criticism in more detail, I consider the current state of research on the relationship between Hegel and Caspar David Friedrich. It is striking to (...) note how little resonance Hegel’s judgment has found in the secondary literature. Going beyond some of the more speculative results of earlier scholarship, I show that by consulting a number of overlooked original German sources and documents from the years 1820-1821 it is possible to precisely determine those paintings of Caspar David Friedrich that Hegel would have known about and even viewed in person at that time. By comparing Hegel’s criticism in the Ascheberg transcript with these particular paintings of Friedrich viewed by Hegel in Dresden, and by furthermore reading this criticism in the larger context of Hegel's considerations on style and the topic of mysteriousness in painting, I argue that a number of consequences can be drawn from the philosopher’s two key reproaches of severity and affectation that are significant for both Hegel scholarship and Caspar David Friedrich research.

This short essay introduces a set of articles I compiled for a special issue of the Journal of Chinese Philosophy in 2011. Most of the essays are revised versions of papers originally presented at the "Kant in Asia" international conference on "The Unity of Human Personhood", held in Hong Kong in May of 2009, and subsequently published in the collection entitled Cultivating Personhood: Kant and Asian Philosophy (Berlin: Walter de Gruyter, 2010). After introducing the papers in the special issue, (...) the essay proposes an unconventional way of mapping the Yijing, according to four "levels of perspectives": 0 + 4 + 12 + (4x12) = 64. I predict that this new map can be used to demonstrate a one-to-one correspondence between the Yijing's 64 gua (hexagrams) and the basic principles of Kant's philosophy. (shrink)

This study focuses on the influence of the work of Carl Stumpf on the thought of Karl Bühler. Our working hypothesis is based on the philosophical program that Bühler attributes to Stumpf and to which several of his works are largely indebted. It is divided into five parts. The first is intended to establish a relationship between Bühler and the School of Brentano to which Stumpf belongs. In the second, I show that Bühler became aware of Brentano's ideas and of (...) Stumpf's program during a stay at the Institute of Psychology of Berlin during the winter semester 1904-1905, and I briefly comment, in the third part, Bühler's references to the work of Stumpf and two of his books in which he defends Stumpf's program against his critics. After having established the solid knowledge that Bühler had of Stumpf's work, I outline, in the fourth part, the main aspects of this program and evaluate, in the fifth, how Bühler uses it in the field of sensory phenomena (gestalt). I conclude this study with several remarks on Stumpf's positive evaluation of the work of Bühler. (shrink)

The article is a reply to three reviews of my book Willensfreiheit (Berlin/New York 2007) which were published in a previous issue of this journal. In the book, I develop a libertarian account of free will that invokes neither uncaused events nor mind-body dualism nor agent causality. Against Bettina Walde’s criticism, I argue that a well-balanced libertarianism can evade the luck objection and that it should not be portrayed as positing tiny causal gaps in an otherwise deterministic world. Against (...) Marcus Willaschek’s Moorean compatibilism, I argue that our ordinary notion of agency commits us to genuine two-way abilities, i. e. to abilities to do otherwise given the same past and laws of nature. Against Christoph Jäger’s defence of van Inwagen’s consequence argument, I insist that this argument for incompati-bilism is seriously flawed and that libertarians are well-advised not to base their position upon it.

There are no ‘correct’ translations. Some are just better than other translations. -/- The Oldest Systematic Program of German Idealism. The German title is: Das Älteste Systemprogramm Des Deutschen Idealismus. This title was made up by Franz Rosenzweig in 1917, when he first published the manuscript. He found the manuscript in the Royal Library in Berlin in 1913. The manuscript suggested date is around 1796 and was done by handwriting research. However, the manuscript is not dated. The Prussian State Library auctioned in March 1913 from the auction of the house Liepmannssohn in Berlin a single sheet on the front and back with Hegel's cursive handwriting. The manuscript was lost during WWII. But Dieter Henrich found it again in 1979 in the “Biblioteka Jagiellonska” in Krakow (Poland), where it is today.

Later research suggests that manuscript had come from the estate of Hegel’s student Friedrich Christoph Förster (1791-1868).

This short review paper focuses on Georg Lind's approach to the moral competence as described in his recent book How To Teach Morality? Promoting Deliberation and Discussion, Reducing Violence and Deceit. Berlin: Logos Verlag. Lind's dual-aspect approach is discussed as one of the leading conceptions of personal moral competence and moral cognition today. Intuitionist approach and "embodied cognition" are not enough, the author claims. As participants of social contexts and institutions, we need manifest, discoursively articulated reflection, self-reflection, and conversation. (...) However, Lind's hypothesis of two leyers of morality, i.e., a conscious and unconscious finds evidence in cognitive sciences too. Lind's approach is not as reductionist as that of radical cognitivists. On the contrary, it combines all relevant aspects of moral cognition discussed right now, worldwide – when cognitive sciences flourish and the challenges for moral mind grow up dramatically.

Leibniz’s short letter to the mathematician and physicist Ludovico Casati of 1689 is a short but interesting text on the Principle of Identity of Indiscernibles, to which it is entirely dedicated. Since there is no watermark in the paper of the letter, the letter is difficult to date, but it is likely that it was written during Leibniz’s stay in Rome, sometime between April and November of 1689 (A 2 2 287–8). When addressing the letter, Leibniz wrote ‘Casani’, but this (...) seems to be a mistake and the real addressee is thought to be Ludovico Casati, nephew of Paolo Casati, the Jesuit mathematician. The letter, reproduced in the Berlin’s Academy edition of Leibniz’s works, was first published by Gerhardt in the Archiv für Geschichte der Philosophie in 1892 (Gerhardt 1892: 53–54). It also appears in Robinet’s Iter Italicum (Robinet 1988: 134–35). But neither Gerhardt nor Robinet provide a philosophical discussion of the letter, and I am not aware of any other philosophical discussion of it. Furthermore, as far as I know, the letter has never been translated into any language. Thus I shall here provide a transcription (from A 2 2 288–89) and a translation of the letter into English, and a philosophical discussion of its treatment of the Identity of Indiscernibles.

Seeking to determine what it is that incites Kierkegaard’s enthusiasm during Schelling’s early lectures at Berlin, then what it is that thoroughly extinguishes his hope in months to follow, I establish: first, that the criticisms of Hegel in Schelling’s negative philosophy depend upon Kantian distinctions and reflect Kant’s critical methodology; secondly, that the leveling function Schelling assigns to these distinctions corresponds to the notion of irony as a destructive force found in The Concept of Irony; finally, that Kierkegaard will (...) come to concretize an account that adheres more closely to Kant’s transition from negative to positive than to Schelling’s.

FISIOLOGIA DO PARTO E DA LACTAÇÃO ANIMAL -/- ANIMAL REPRODUCTION: PHISIOLOGY OF PARTURITION AND ANIMAL LACTATION -/- Emanuel Isaque Cordeiro da Silva Departamento de Zootecnia da UFRPE WhatsApp: (82)98143-8399 -/- 1. INTRODUÇÃO O sucesso biológico do processo de reprodução culmina com a sobrevivência das crias. Durante a gestação, o feto desenvolve-se no útero materno protegido das influências externas, e obtendo os nutrientes e o oxigênio através da mãe. O parto é o processo biológico que marca o fim da gestação e (...) o início da vida extrauterina do animal. Para garantir a sobrevivência do recém-nascido o parto deve ser um processo controlado para que se inicie unicamente quando o feto tiver alcançado desenvolvimento suficiente que lhe permita enfrentar a vida extrauterina. Após o nascimento, a secreção de leite pela glândula mamária proporciona ao neonato tanto os nutrientes necessários para seu desenvolvimento como as defesas (imunoglobulinas) que lhe protegerão contra as possíveis infecções durante as primeiras fases de sua vida. Parto e lactação constituem a última etapa de um ciclo reprodutivo completo nas fêmeas dos animais domésticos, estando ambos os processos regulados e sincronizados por complexas mudanças hormonais na mãe. Estas mudanças são, em última análise, provocadas e governadas pelo próprio feto ou recém-nascido, o qual acomoda as respostas maternas às suas necessidades garantindo a sua sobrevivência. 2. O PARTO O parto é definido como o processo fisiológico pelo qual ocorre a expulsão de um ou mais fetos maduros, bem como das membranas fetais existentes no útero materno. Este processo é desencadeado por uma interação complexa entre as hormonas maternas (fatores maternos) e fetais (fatores fetais). Para que se realize a expulsão do feto é necessário que o útero deixe de ser um órgão quiescente, essencial para a manutenção da gestação, para ser um órgão contrátil. Ao mesmo tempo, o cérvix ou colo uterino, que durante a gestação permanece firmemente fechado para impedir a expulsão prematura do feto e evitar a entrada de agentes infecciosos, relaxa e dilata para facilitar a passagem do feto na hora do parto. Esta modificação na atividade do útero e do colo uterino, ocorrem como consequência das mudanças hormonais que o organismo materno experimenta à medida que a data do parto se aproxima. 2.1 Fatores maternos A gestação dos animais domésticos ocorre com elevada concentração de progesterona que, dependendo da espécie animal, é secretada seja pelo corpo lúteo do ovário (vaca, porca e cabra) ou pela placenta (ovelha e égua). A progesterona desempenha um papel fundamental durante a gestação, inibindo as contrações da musculatura lisa do útero (miométrio), permitindo assim a acomodação do feto durante o seu crescimento. Os estrogênios, estimulantes da atividade contrátil do miométrio, mantêm-se a baixas concentrações durante a maior parte da gestação. À medida que se aproxima o momento do parto, os níveis destes hormônios esteroides modificam-se, produzindo-se a diminuição nos níveis circulantes da progesterona ao mesmo tempo que se incrementam os valores sanguíneos dos estrogênios (figura 1). A redução dos níveis de progesterona suprime a sua ação inibitória sobre a atividade contrátil do miométrio, permitindo que se manifestem os efeitos estimulantes dos estrogênios sobre este órgão. A concentração de estrogênios começa a aumentar geralmente no final da gestação, atingindo os seus valores máximos no momento do parto (figura 1). O aumento da concentração de estrogênios favorece a atividade contrátil espontânea do útero ao: a) estimular a síntese de proteínas contráteis; b) aumentar, sob medida, a sensibilidade do miométrio uterino à ação estimulante das prostaglandinas; c) induzir a formação de receptores de oxitocina no útero. -/- Figura 1. Níveis de progesterona e estrógenos durante a gestação e parto das espécies ovina, caprina, suína e bovina. Fonte: HAFEZ, 2013. Os estrogênios estimulam a síntese e secreção de prostaglandina (PGF2a), que constitui o elemento essencial para o início do parto devido aos efeitos que esta substância provoca. Assim, nas fêmeas, cujos níveis de progesterona gestacional dependem da presença do corpo lúteo, a secreção de PGF, origina a regressão deste (luteólise), com a consequente diminuição da progesterona a níveis basais. Além disso, a PGF2a origina contrações de crescente intensidade no útero sensibilizado pela ação dos estrogênios. Esta ação contrátil da PGF2a deve-se a um aumento da concentração de cálcio intracelular das fibras musculares uterinas. A PGF2a também está envolvida no relaxamento do colo do útero, inibindo a formação de colágeno cervical ao mesmo tempo que estimula a síntese de enzimas (colagenase) que degradam a matriz de colágeno formado no início da gestação. A dilatação do colo do útero está também associada à pressão que o feto exerce sobre o mesmo e, no caso da porca, a relaxina pode também estar envolvida. Esta hormona é também de grande importância para a preparação do parto em todas as espécies animais, uma vez que é responsável pelo relaxamento dos ligamentos e músculos que rodeiam o canal pélvico para favorecer a separação da sínfise púbica durante a expulsão do feto. Nos grandes animais (vaca, égua) as mudanças que ocorrem nos tecidos e ligamentos pélvicos são muito evidentes e constituem um sintoma de parto iminente. O início do parto, ou primeira fase do parto, caracteriza-se pelo aumento das contrações uterinas provocadas pela PGF2a coincidindo com a dilatação do colo uterino para permitir a passagem do feto para o canal do parto, momento em que começa a segunda fase do parto. A distensão vaginal que produz-se para a passagem do feto pelo canal do parto origina um estímulo nervoso que viaja através da medula espinal para o hipotálamo, onde se encontram os neurônios responsáveis pela síntese de oxitocina. As terminações nervosas destes neurónios são projetadas para o lobo posterior da hipófise (neurohipófise), onde a oxitocina é secretada para ser, posteriormente , transportada pela circulação sanguínea. Este reflexo neuroendócrino chamado reflexo de Ferguson determina a secreção súbita de oxitocina, provocando o aumento tanto na intensidade como na frequência das contrações uterinas necessárias para a expulsão final do feto. O papel da oxitocina é ativar a conclusão do processo de expulsão, uma vez que esta hormona não está envolvida no início do parto. A alteração mais significativa entre a gestação e o parto é a alteração na atividade contrátil do miométrio uterino. Esta mudança é devido às alterações hormonais que ocorrem na mãe quando a gestação chegou a fim. No entanto, para que estes mecanismos maternos sejam acionados, é necessário que o feto indique de alguma forma à mãe o seu estado de desenvolvimento, de modo que o nascimento realize-se quando o feto estiver preparado para enfrentar a vida extrauterina. 2.2 Fatores fetais A destruição experimental da hipófise e/ou das glândulas adrenais do feto origina o prolongamento da gestação nos animais domésticos. Pelo contrário, a administração exógena de cortisol (corticosteroides adrenais), ou do seu precursor hipofisário (ACTH), à circulação fetal provoca, em poucas horas, o início do parto. Estes fatos evidenciam a importância do eixo hipófise-adrenal do feto para desencadear o início do parto (figura 2). Figura 2. Mecanismos fetais que controlam o parto em ovelhas. Fonte: LIGGINS et al, 1972. No final da gestação, o feto maduro apresenta um aumento da concentração de corticosteroides plasmáticos devido ao efeito estimulante da hormona adrenocorticotróide (ACVH) secretada pela hipófise fetal sobre as glândulas adrenais do feto. Os corticosteroides fetais por sua vez estimulam as enzimas placentárias para transformar a progesterona em estrogênio. O resultado final é a diminuição dos níveis de progesterona ao mesmo tempo que se eleva a concentração de estrogênios que, por sua vez, estimulam a libertação de PGF2a responsável pelas contrações uterinas. Este raciocínio explica algumas doenças caracterizadas por gestação prolongada em ovelhas, como ocorre na África do Sul, onde estes animais são obrigados, durante as épocas de seca, a ingerir as folhas de um arbusto chamado Salsola tuberculate. O prolongamento da gestação ocorre quando estas folhas são ingeridas durante o último terço da gestação cujos efeitos estão relacionados com a supressão do eixo hipotálamo-hipófise, com o qual as adrenais não recebem o estímulo necessário (ACTH) para a síntese e liberação de corticoides. O efeito contrário é observado nas cabras da raça Angorá, nas quais se produzem, com relativa frequência, partos prematuros que podem estar relacionados com um desenvolvimento precoce das glândulas adrenais. Isto significa que, nos animais domésticos, o feto determina a data do parto. O sinal hormonal que indica à mãe o grau de maturidade do feto é o desenvolvimento do eixo hipotálamo-hipófise-adrenal que origina o aumento na secreção de corticoides fetais que são os responsáveis por desencadear as alterações hormonais no organismo materno necessárias para iniciar o parto. A figura 2 mostra como a remoção da hipófise e as adrenais do feto prolongam a gestação, enquanto a administração exógena de ACTH ou corticoides (cortisol) ao feto originam um parto prematuro. O momento em que ocorre o aumento da concentração plasmática de corticoides no feto varia de acordo com a espécie: de 25 a 30 dias antes do parto na vaca, de 7 a 10 dias na porca e de 2 a 3 dias na ovelha. 2.3 Desenvolvimento e fases do parto O parto inicia-se com o início das contrações peristálticas e regulares do miométrio uterino ao mesmo tempo que o colo do útero se dilata progressivamente. Nas fêmeas que gestam um único feto (monotecas), as contrações começam na extremidade anterior do córneo uterino, enquanto que nas espécies que gestam vários fetos (politocas) as contrações começam pela extremidade cervical para começar a expulsar o feto que se encontra mais próximo do cérvix. Durante o parto são reconhecidas três fases: 1. Fase preparatória - Na qual as contrações uterinas estimulam a rotação do feto (fêmeas monotecas) para adotar a posição dorsal (extremidades anteriores e cabeça forçadas contra o cérvix) que lhe permite oferecer a menor resistência para sua expulsão. A PGF2a provoca as contrações miometriais e a dilatação do cérvix, deslocando o feto contra e através desta estrutura. 2. Fase de expulsão - A passagem do feto através do colo uterino e da vagina causam a completa dilatação destas estruturas, originando a secreção de oxitocina (reflexo de Ferguson), que provoca contrações de maior frequência e intensidade. Por sua vez, estas contrações uterinas são reforçadas pela pressão e contração dos músculos abdominais, chegando estes últimos a ser a força principal (forças de expulsão) envolvida no processo de expulsão do feto. O cordão umbilical rompe-se bem ao levantar-se a mãe ou pelos movimentos do recém-nascido. 3. Fase de expulsão da placenta - Após o parto, as contrações rítmicas do útero continuam a facilitar a expulsão da(s) placenta(s). O tempo necessário para este processo varia de acordo com a espécie animal. Este processo é rápido na égua, já que a separação do corion (membrana fetal) de sua inserção uterina ocorre durante a expulsão do feto, com o qual o parto deve ser concluído rapidamente ou, caso contrário, o potro se asfixiaria. Nos ruminantes, a expulsão da placenta cotiledonaria é um processo mais lento que exige a separação dos cotilédones (membrana fetal) das carúnculas do útero. Por conseguinte, a troca de nutrientes e oxigênio entre a mãe e o feto continua até que este tenha sido totalmente expelido, devido ao cordão umbilical destes animais ser bastante longo. Nas fêmeas politocas, como a porca, geralmente as placentas de vários leitões são expulsadas no final, quando os leitões já foram expelidos, se bem que o último leitão poderá ser expelido durante a expulsão da massa placentária. 3. LACTAÇÃO A lactação constitui o processo que define os mamíferos como classe biológica. O desenvolvimento pós-natal dos mamíferos vai depender, em grande medida, dos nutrientes e defesas fornecidos pela mãe através da secreção de leite (imunoglobulinas). Assim, uma vez concluído o desenvolvimento gestacional do feto, a glândula mamária irá substituir, de certa forma, a função nutritiva e protetora da placenta durante a gestação. 3.1 Anatomia funcional da glândula mamária A estrutura funcional da glândula mamária é muito semelhante em todos os mamíferos, embora o tamanho, forma e número de glândulas varia dependendo da espécie animal. As glândulas mamárias desenvolvem-se como estruturas pares cujo número varia de um par (égua, cabra e ovelha), dois pares (vaca) até sete ou nove (porca). A localização das glândulas também difere sendo inguinal em vaca, égua, cabra e ovelha, enquanto que na porca, cadela e gata se estendem por todo o comprimento do tórax e abdômen. Nos animais domésticos em geral as glândulas mamárias recebem o nome de úberes. Tomando como modelo a vaca, a glândula mamária se organiza em duas estruturas: o estroma, formado por tecido conjuntivo procedente dos ligamentos suspensório medial, localizado entre os dois pares de glândulas, dando suporte à segunda estrutura que é o tecido secretor. Este é formado por acúmulos de células secretoras formando estruturas ocas chamadas alvéolos, que são as unidades fundamentais secretoras de leite. Os alvéolos estão circulados internamente por células epiteliais (secretoras) e rodeados externamente por células mioepiteliais contráteis, cuja contração origina a ejeção do leite (figura 3). O agrupamento de vários alvéolos adjacentes formam um lobo secretor. Figura 3. Diagrama de um agregado de alvéolos na glândula mamária de uma cabra. Fonte: COWIE et al, 1980. Os lobos expelem a secreção através de ductos que, por sua vez, drenam os ductos galactóforas (ductos lácteos) de maior diâmetro, para desembocar em áreas especializadas em armazenar o leite chamadas cisternas (vaca, cabra). Finalmente, a cisterna abre-se para o exterior através do canal papilar da teta. A presença do músculo liso na teta permite-lhe agir como esfíncter para impedir que o leite seja expelido passivamente do interior da glândula. O mamilo/teta é provido de numerosos receptores sensitivos cuja excitação durante a ordenha ou amamentação vai desencadear estímulos nervosos de grande importância para a manutenção da lactação. 3.2 Desenvolvimento da glândula mamária (mamogênese) A glândula mamária difere das demais glândulas do organismo no escasso desenvolvimento que apresenta no nascimento da fêmea, o qual não se inicia até que esta não atinja a puberdade. O início da atividade cíclica do ovário (puberdade) dá origem à síntese de estrogênios (fase folicular do ciclo estral) e progesterona (fase lútea). Os estrogênios originam o alongamento e ramificação dos ductos e a formação de pequenas massas esféricas de células (os futuros alvéolos). Embora este desenvolvimento seja dependente do estrogênio, é também necessária a ação sinérgica da prolactina, hormona do crescimento (GH) e corticoides adrenais, como demonstrado pelos estudos realizados em ratos aos quais foi removida a hipófise, glândulas suprarrenais e ovários (figura 4). A função da progesterona no desenvolvimento da glândula mamária é estimular o crescimento do lobo-alveolar, mas como no caso anterior também requer a ação conjunta dos hormônios acima mencionados. Figura 4. Hormonas relacionadas com o crescimento da glândula mamária e início da secreção de leite na rata hipofisectomizada-adrenoectomizada-ovariectomizada. Fonte: COWIE, 1980. O desenvolvimento da glândula, durante cada ciclo estral, vai depender da duração da fase folicular (níveis elevados de estrogênio), já que nas restantes fases do ciclo, quando os níveis de estrogênio são baixos, os ductos sofrem uma ligeira regressão. Nas espécies com ciclos curtos (rata), em que a fase folicular do ciclo é predominante, enquanto a fase lútea é quase inexistente, verifica-se um grande desenvolvimento dos ductos; enquanto que aquelas que apresentam um corpo lúteo funcional de longa duração (cadela e primatas), além do crescimento dos ductos, mostram um grande desenvolvimento lóbulo-alveolar semelhante ao que ocorre na gestação. É durante a gestação que o sistema alveolar sofre uma hipertrofia considerável, resultando em lobos proeminentes e no desenvolvimento da luz interna dos alvéolos, fato que é evidente na maioria dos animais domésticos por volta da metade do período gestacional. Em algumas espécies, as células que circundam interiormente os alvéolos contêm produtos secretores, indicando que a glândula mamária já está preparada para a fase da lactação. O desenvolvimento glandular durante a gestação deve-se ao efeito conjunto da progesterona e dos estrogênios com as hormonas hipofisárias acima mencionadas: prolactina, hormona do crescimento (GH) e adrenocorticotropina (ACTH). A proporção entre estrogênios e progesterona varia de acordo com a espécie, mas geralmente é necessária uma maior concentração de progesterona (proveniente do corpo lúteo ou da placenta). Quanto às hormonas hipofisárias, a prolactina desempenha um papel fundamental na diferenciação da glândula mamária (mesmo a baixas concentrações) ao estimular o desenvolvimento do epitélio secretor dos alvéolos. A GH favorece o crescimento dos ductos e a ACTH estimula a secreção de corticoides nas adrenais que, por sua vez, favorecem de forma generalizada o crescimento das glândulas. 3.3 Secreção da glândula mamária (lactogênese) A lactogênese, ou o processo pelo qual se produz a síntese e secreção do leite pela glândula mamária, começa no final da gestação coincidindo com o desencadeamento do parto. O primeiro leite formado imediatamente antes ou depois do parto é denominado colostro. No entanto, a lactação não pode desenvolver- se completamente até que se inicie o processo de parto. Isto deve-se ao fato de que o processo de lactação resulta de uma interação complexa de hormonas que preparam a glândula mamária para a secreção do leite. Os requisitos hormonais mínimos para o início da lactogênese são: aumento da secreção de estrogênios, prolactina e corticoides, juntamente com a diminuição da concentração de progesterona, perfis hormonais que estão intimamente relacionados com o desencadeamento do parto. Isto deve-se ao fato de que a progesterona inibe a atividade lactogênica da prolactina bloqueando a formação dos seus receptores na glândula mamária durante a gestação impedindo, assim, a prolactina de sintetizar os componentes fundamentais do leite. Pelo contrário, o aumento da concentração de estrogênios no final da gestação (figura 1, na seção do parto) estimula a síntese, o armazenamento e a secreção hipofisária de prolactina. Assim, apesar da glândula mamária estar preparada para iniciar a secreção de leite, muito antes da data prevista para o parto, a elevada concentração de progesterona (existente durante esse período de gestação) impede a fase láctea (saída do leite pelas tetas) de ocorrer antes da expulsão do feto. Desta forma, o feto poderá beneficiar das vantagens que o fornecimento do colostro materno irá trazer para a sua sobrevivência (imunização, nutrição e favorecimento da exoneração do mecônio). O aumento da concentração de estrogênios nos dias que antecederem o parto resulta num rápido aumento das concentrações plasmáticas de prolactina e corticoides. A prolactina é a hormona lactogênica mais importante na síntese dos componentes do leite. No entanto, para que esta hormona possa exercer a sua função, é necessária a participação dos corticoides, já que os mesmos são os responsáveis pelo desenvolvimento das organelas citoplasmáticas (retículo endoplasmático rugoso e aparelho de Golgi) onde se realiza a síntese do leite. No desenvolvimento da lactogênese, para além da prolactina e dos corticoides, participam também outras hormonas como a insulina, a tiroxina e o hormônio do crescimento. A insulina estimula a proliferação de novas células epiteliais na glândula mamária, enquanto a tiroxina, embora não seja essencial para a lactação, pode influenciar no volume de leite produzido pela fêmea (alta produção leiteira). Por último, a hormona do crescimento favorece, em geral, a lactação, existindo atualmente um interesse considerável no uso desta hormona para promover a produção adicional de leite em vacas através da sua administração exógena (trabalho e projeto desenvolvido pela professora titular e médica-veterinária do IFPB Campus Sousa Marianne Christina Velaqua). 3.3.1 Síntese e secreção dos componentes do leite Os principais constituintes do leite são: proteínas (caseína, alfa-lactalbumina, albumina sérica e imunoglobulinas), açúcares (lactose), gorduras (principalmente sob a forma de triglicerídeos), vitaminas, minerais e citrato (no caso dos ruminantes). As proteínas (caseína e alfa-lactalbumina) são sintetizadas no retículo endoplasmático rugoso e posteriormente embaladas em vesículas secretoras do aparelho de Golgi para serem liberadas da célula para a luz alveolar mediante um processo de exocitose. A lactose é o principal açúcar do leite que, além disso, atua regulando a pressão osmótica do mesmo de modo que o volume de leite que a glândula mamária segrega está diretamente relacionado com a quantidade de lactose presente. A síntese da lactose ocorre no aparelho de Golgi pela condensação de glicose e galactose; esta reação é catalisada por uma enzima (lactose sintetase) presente na membrana do aparelho de Golgi que, por sua vez, é ativada pela proteína alfa-lactalbumina. Esta proteína só aparece na glândula mamária e é essencial para a síntese da lactose, o que demonstra que este açúcar é exclusivamente formado no leite. A lactose é também embalada junto com o cálcio, o fosfato e as proteínas nas vesículas secretoras para ser expulsada ao lúmen alveolar por exocitose. As imunoglobulinas (anticorpos IgA) são formadas pelas células plasmáticas, derivadas dos linfócitos B do sangue, como consequência da exposição da mãe a diferentes microrganismos. Estes anticorpos passam para a glândula mamária por migração dessas células a partir dos tecidos adjacentes. Os triglicerídeos são sintetizados no citoplasma e no retículo endoplasmático liso a partir de ácidos graxos provenientes da circulação sanguínea; em seguida, unem-se formando glóbulos de gordura que se dirigem até o vértice da membrana plasmática para serem finalmente expelidos para a luz do alvéolo, rodeados pela membrana, formando assim uma dispersão de glóbulos de gordura (figura 5). Figura 5. Estrutura de três células alveolares durante a síntese do leite. Fonte: COWIE, 1980. Do ponto de vista quantitativo, a caseína e os triglicerídeos constituem as proteínas e as fontes de energia, respectivamente, mais importantes do leite. Por último, o citrato é um intermediário do metabolismo da glicose que ocorre em grande concentração no leite dos ruminantes. Este composto é também englobado no interior das vesículas secretoras, junto com os outros compostos, para sua expulsão à luz alveolar. A composição do leite varia dependendo da espécie animal, e difere também até entre a mesma espécie. Estas variações estão relacionadas com a raça, idade, estágio de lactação e estado nutricional do animal. O teor de gordura no leite de ovelhas, porcas, cadelas e gatas varia entre 7 e 10%. No gado leiteiro estes valores variam de 3,5 a 5,5%, dependendo da raça. Em relação às cabras, os valores de gordura são muito semelhantes aos das vacas, enquanto o leite das éguas é o que tem menor teor de gordura (tabela 1).

Composição do leite em várias espécies (%). Fonte: JACOBISON, 1984. 3.4 Manutenção da lactação (galactopoiese) A capacidade da glândula mamária de secretar um grande volume de leite começa em/ou imediatamente antes do parto, para aumentar no período pós-parto durante um tempo variável e, posteriormente, diminuir de forma gradual. Em geral, existe um paralelismo entre a atividade secretora da glândula e a procura de leite por parte do lactente. Isto deve-se ao fato de sucção pelo lactente, ou a extração por ordenha, que constituem o fator fundamental para a manutenção da lactação. A sucção estimula a lactação de duas formas: a) reduzindo os efeitos inibitórios da pressão intramamária produzida pela acumulação de leite, e b) estimulando intensamente a secreção de hormonas necessárias para manter a síntese e secreção de leite nos alvéolos. As hormonas que desempenham um papel fundamental na manutenção da lactação são: I) a prolactina, que é responsável pela estimulação da síntese e secreção de leite nas células epiteliais nos alvéolos, e 2) a oxitocina, que provoca a contração das células musculares que circundam externamente os alvéolos e os ductos (células mioepiteliais). A libertação de ambos os hormônios ocorre como resultado de um reflexo neuroendócrino originado pela estimulação do mamilo. 3.4.1 Secreção reflexa de prolactina A secreção de prolactina é regulada por dois fatores hipotalâmicos: a dopamina, que inibe a secreção de prolactina e um fator cuja identidade não está bem definida, conhecido como fator liberador de prolactina (PRF)que estimula a liberação deste hormônio. O estímulo sensorial originado como sequência da estimulação do mamilo, pela sucção do lactente, é transportado através da medula espinhal para o hipotálamo, onde atua na inibição da dopamina ou estimulando a secreção do PRF para desencadear a secreção de prolactina da adenohipófise para a circulação sanguínea (figura 6). Figura 6. Reflexos neuroendócrinos secretores de prolactina e oxitocina. Fonte: HAFEZ, 2000. A prolactina estimula a secreção dos componentes do leite para a luz dos alvéolos, afim de repor o volume de leite extraído durante a última ordenha ou sucção. Ao mesmo tempo, a prolactina induz a síntese das proteínas, incluindo a alfa-lactalbumina para estimular novamente a síntese da lactosa, bem como as enzimas necessárias para a produção dos triglicerídeos. Desta forma, a secreção de prolactina originada pelo lactente durante o aleitamento proporciona um mecanismo simples para combinar o volume de produção de leite com as necessidades do lactente. A quantidade de prolactina liberada durante cada período de sucção depende do número de crias, da duração do estímulo e dos intervalos de tempo decorridos entre os períodos de sucção (ou ordenha). No caso das vacas leiteiras, as ordenhas são geralmente realizadas de doze em doze horas, intervalo de tempo suficiente para manter a lactogênese. Os valores plasmáticos de prolactina aumentam imediatamente após o início da ordenha, mas os valores mais elevados são obtidos cerca de meia hora após o início do estímulo (ordenha ou sucção). A secreção de prolactina e a produção de leite são influenciadas de alguma forma pelo fotoperíodo, uma vez que, em alguns animais se comprovou como o aumento do número de horas de exposição à luz dá origem a um aumento da concentração de prolactina circulante, bem como uma maior produção de leite (entre 6 e 10%) (trabalho e projeto elaborado pelos estudantes do curso técnico em agropecuária e da graduação em Medicina Veterinária do IFPB Campus Sousa sob a coordenação e orientação da profa. Me. Esp. Marianne C. Velaqua). 3.4.2 Reflexo da ejeção do leite A sucção do mamilo pelo lactente estimula os receptores sensoriais presentes nesta estrutura, originando a geração de impulsos nervosos que são transmitidos pelas vias nervosas ascendentes da medula espinhal para os corpos celulares produtores de oxitocina no hipotálamo. O estímulo desencadeia a síntese e liberação de um bolo de oxitocina através das terminações nervosas dos núcleos hipotalâmicos para a neurohipófise, da qual é transmitida, através do sangue, para a glândula mamária, provocando a contração das células mioepiteliais que rodeiam os alvéolos (figura 6). Além da estimulação direta do mamilo provocada pela sucção, qualquer estímulo relacionado à ordenha é capaz de gerar o reflexo da ejeção, por exemplo: os estímulos sensoriais auditivos (ruído dos cubos na hora da ordenha), visuais (ambiente da sala de ordenha), táteis (lavagem manual dos mamilos antes da ordenha) e os estímulos olfatórios que se produzem em torno do animal. O desencadeamento do reflexo de ejeção pelos estímulos sensoriais, que não estão diretamente relacionados com a sucção ou ordenha, indica a possível participação de centros superiores do sistema nervoso central para controlar a secreção de oxitocina. Esta teoria é baseada em que os estímulos relacionados com situações de estresse em animais de estimação (medo, ansiedade, frio, etc.) inibem a ejeção do leite. A contração das células mioepiteliais gera um aumento da pressão intra-alveolar mamária, provocando o deslocamento do leite para os ductos maiores da glândula. Este efeito é popularmente conhecido como diminuição do leite e constitui um mecanismo fisiológico muito eficaz para controlar a expulsão do leite para o mamilo, assegurando que a ejeção do leite se realize unicamente quando o lactente o demanda. O efeito estimulante da oxitocina é de grande importância já que a maior parte do leite se encontra nos alvéolos e nos ductos, com o qual, a ausência deste hormônio provocaria um lento movimento do leite para a cisterna do úbere e, portanto, uma menor quantidade de leite. Assim, quando os alvéolos e ductos menores são contraídos, ocorre o relaxamento dos ductos principais, bem como da cisterna (ruminantes) e do mamilo, o que dá origem a um aumento destas estruturas para alojar o volume de leite expelido. Como resultado da volumosa ejeção do leite dos alvéolos e ductos menores, ocorre um aumento da pressão intramamária de modo que o lactente terá que vencer a resistência do esfíncter do mamilo para poder extrair o leite. A produção de leite pela glândula mamária diminui gradualmente à medida que os intervalos de tempo entre os dois períodos de amamentação do lactente diminuem e os estímulos necessários para manter as concentrações de prolactina e oxitocina na circulação sanguínea. A diminuição ou cessação da secreção de leite, geralmente coincide com a mudança na alimentação das crias (desmame) para passar à dieta característica da espécie. 3.5 Colostro O colostro é o primeiro leite que se forma na glândula mamária coincidindo com o parto. A ingestão de colostro por recém-nascidos é de grande importância para a sua sobrevivência, não só pelo seu elevado valor nutritivo, mas também pelo seu teor em imunoglobulinas (IgA) que lhe confere a imunização passiva necessária para o proteger contra patologias. Em algumas espécies (homem, coelho e cobaia) grande parte dos anticorpos passam para a circulação do feto através da placenta durante a gestação. Nos animais domésticos (vaca, égua, ovelha, cabra, porco) as características da placenta (número de camadas entre a circulação materna e fetal) não permitem a passagem destas proteínas. Como resultado, a imunização das crias nestas espécies animais vai depender da transferência das imunoglobulinas através do colostro. O epitélio intestinal dos recém-nascidos permite a passagem destas imunoglobulinas durante as primeiras 24 a 48 horas de vida. Passado este tempo, o epitélio torna-se impermeável à passagem dos anticorpos, fato que põe em evidência a importância que tem para os animais recém-nascidos e desprovidos de defesas a ingestão do colostro durante os primeiros dias. A composição do colostro caracteriza-se (em relação ao leite normal) por um teor mais elevado de proteínas, vitaminas, minerais e uma menor concentração de lactose. A composição do colostro muda gradualmente durante os primeiros três dias após o parto para se transformar em leite normal. 4. RESUMO E PRIMEIRAS CONCLUSÕES O parto, ou processo fisiológico pelo qual se expulsa o feto, é o resultado da maturação sequencial de um sistema de comunicação hormonal. A sequência inicia-se no sistema nervoso central do feto de onde os sinais são transmitidos e amplificados, através da hipófise, para as glândulas adrenais fetais, as quais respondem ao estímulo mediante a secreção de cortisol. O aumento da concentração de cortisol por parte do feto indica que este conseguiu o desenvolvimento necessário para enfrentar a vida extrauterina e, portanto, é hora de interromper a gestação. O cortisol atua sobre a placenta para aumentar a secreção de estrogênios que, por sua vez, estimulam a síntese e a liberação de prostaglandinas. O resultado é a diminuição da progesterona, que é a hormona encarregada de manter a gestação ao inibir as contrações espontâneas do útero, impedindo assim a expulsão prematura do feto. O útero, sob os efeitos da prostaglandina, começa a contrair-se ao mesmo tempo que o colo uterino amolece e dilata progressivamente (fase preparatória do parto). A passagem do feto ao canal do parto origina a secreção reflexa de oxitocina (fase de expulsão), causando contrações de maior frequência e intensidade que culminam com a expulsão do feto. Finalmente, as contrações uterinas continuam durante algum tempo até que finalmente é expulsa a placenta (fase de expulsão da placenta). O desenvolvimento da glândula mamária durante a gestação e a subsequente capacidade desta estrutura para secretar leite, coincidindo com o parto, oferece aos animais pertencentes à classe biológica dos mamíferos a vantagem de alimentar as suas crias para assegurar a sua sobrevivência durante as primeiras fases do seu desenvolvimento e, portanto, a continuidade da espécie. A lactação constitui um dos processos fisiológicos mais complexos em consequência do grande número de hormonas que, segregadas de forma coordenada, controlam as diferentes fases pelo que atravessa este processo: I) mamogênese ou desenvolvimento dos dutos e estruturas lóbulo-alveolares durante a gestação; 2) lactogênese ou síntese láctea por células epiteliais e sua secreção para a luz alveolar coincidindo com o parto, e 3) galactopoiese ou manutenção da síntese e secreção do leite como consequência da sua extração da glândula mamária seja pela sucção da cria ou pela ordenha. -/- Emanuel Isaque Cordeiro da Silva – Departamento de Zootecnia da UFRPE.
