Brouwer's philosophy of mathematics is usually regarded as an intra-subjective, even solipsistic approach, an approach that also underlies his mathematical intuitionism, as he strived to create a mathematics that develops out of something inner and a-linguistic. Thus, points of connection between Brouwer's mathematical views and his views about and the social world seem improbable and are rarely mentioned in the literature. The current paper aims to challenge and change that. The paper employs a socially oriented prism to examine Brouwer's views (...) on the construction, use, and practice of mathematics. It focuses on Brouwer's views on language, his social interactions, and the importance of group context as they appear in the significs dialogues. It does so by exploring the establishment and dissolution of the significs movement, focusing on Gerrit Mannoury's influence and relationship with Brouwer and analyzing several fragments from the significs dialogues while emphasizing the role Brouwer ascribed to groups in forming and sharing new ideas. The paper concludes by raising two questions that challenge common historical and philosophical readings of intuitionism. (shrink)

The translation of the book of Hering comes to take from oblivion this important work, filling another hole in the history of phenomenology. Jean Héring (1890-1960), one of the influential thinkers of the earliest period of the phenomenology, as a member of the Göttingen circle created by Edmund Husserl. He was the first to present and popularize phenomenology in France. of particular signifance is his influence on Emmanuel Levinas, who came to the University of Strasbourg in 1923. There Hering (...) introduced him to phenomenology and then sent him to Husserl in Freiburg. Hering's book "Phénomenologie et Philosophie religieuse. Étude sur la théorie de la Connaissance religieuse" presents a specific phenomenological mode of analysis in the area of religious experience and religious knowledge. In it, Hering represented the viewpoint of the early Husserl's understanding of the tasks and purposes of the phenomenology. (shrink)

The notion of signification is an important part of Hobbes's philosophy of language. It also has broader relevance, as Hobbes argues that key terms used by his opponents are insignificant. However Hobbes's talk about names' signification is puzzling, as he appears to have advocated conflicting views. This paper argues that Hobbes endorsed two different views of names' signification in two different contexts. When stating his theoretical views about signification, Hobbes claimed that names signify ideas. Elsewhere he talked as if words (...) signified the things they named. Seeing this does not just resolve a puzzle about Hobbes's statements about signification. It also helps us to understand how Hobbes's arguments about insignificant speech work. With one important exception, they depend on the view that names signify things, not on Hobbes's stated theory that words signify ideas. The paper concludes by discussing whether arguments about insignificant speech can provide independent support for Hobbes's views about other issues, such as materialism. (shrink)

Moral circles help define the boundaries of one’s moral consideration. One’s moral circle may provide insight into how one perceives or treats other entities. A data-driven model exploration was conducted to explore predictors and prediction models. Candidate predictors were built upon past research using moral foundations and political orientation. Moreover, we also employed additional moral psychological indicators, i.e., moral reasoning, moral identity, and empathy, based on prior research in moral development and education. We used model exploration methods, i.e., Bayesian (...) model exploration, Bayesian model averaging, and elastic-net regression. The study successfully replicated past research supporting the relationship between moral foundations, political orientation, and the moral circle. Additional moral psychological constructs, such as post-conventional moral reasoning and moral identity, significantly predicted the moral circle width. The identified components of the moral circle were conceptually related to phronesis, i.e., practical wisdom. We discussed the educational implications of the findings, particularly those related to moral education focusing on phronesis cultivation, multiculturalism and global citizenship, and climate justice.

Roughly put, explanatory circles — if any exist — would be propositions such that (i) each explains the next, and (ii) the last explains the first. In this paper, I give two arguments for the view that there are explanatory circles. The first argument appeals to general relativistic worlds in which time is circular. The second argument appeals to special science theories that describe feedback loops. In addition, I show that three standard arguments against explanatory circles are unsuccessful.

Friedrich Nietzsche was among the figures from the history of nineteenth century philosophy that, perhaps surprisingly, some of the Vienna Circle’s members had presented as one of their predecessors. While, primarily for political reasons, most Anglophone figures in the history of analytic philosophy had taken a dim view of Nietzsche, the Vienna Circle’s leader Moritz Schlick admired and praised Nietzsche, rejecting what he saw as a misinterpretation of Nietzsche as a militarist or proto-fascist. Schlick, Frank, Neurath, and Carnap (...) were in different ways committed to the view that Nietzsche made a significant contribution to the overcoming of metaphysics. Some of these philosophers praised the intimate connection Nietzsche drew between his philosophical outlook and empirical studies in psychology and physiology. In his 1912 lectures on Nietzsche, Schlick maintained that Nietzsche overcame an initial Schopenhauerian metaphysical-artistic phase in his thinking, and subsequently remained a positivist until his last writings. Frank and Neurath made the weaker claim that Nietzsche contributed to the development of a positivistic or scientific conception of the world. Schlick and Frank took a further step in seeing the mature Nietzsche as an Enlightenment thinker. (shrink)

The history of early analytic philosophy, and especially the work of the logical empiricists, has often been seen as involving antagonisms with rival schools. Though recent scholarship has interrogated the Vienna Circle’s relations with e.g. phenomenology and Neo-Kantianism, important works by some of its leading members are involved in responding to the rising tide of Lebensphilosophie. This paper will explore Carnap’s configuration of the relation between Lebensphilosophie and the overcoming of metaphysics, Schlick’s responses to Schopenhauer and Nietzsche, and Neurath’s (...) reaction against Spengler.

Hermeneutic studies of science locate a circle at the heart of scientific practice: scientists only gain knowledge of what they, in some sense, already know. This may seem to threaten the rational validity of science, but one can argue that this circle is a virtuous rather than a vicious one. A virtuous circle is one in which research conclusions are already present in the premises, but only in an indeterminate and underdeveloped way. In order to defend the (...) validity of science, the hermeneuticist must describe a method by which a vague and confused initial knowledge of nature gets transformed into a clear and determinate knowledge of nature. I consider three such methods. The first is regressus demonstrativa, favoured by the physicians of Padua during the fifteenth and sixteenth centuries. The second is mathēsis, introduced by Martin Heidegger in his discussion of seventeenth-century science. The third is Denkstil, a key concept in Ludwik Fleck’s history of syphilology. I conclude by listing three desiderata for a hermeneutic science studies: that it be anti-metaphysical, historical, and sociological. --- Reprinted in: Erich Otto Graf, Martin Schmid & Johannes Fehr (eds.), Fleck and the Hermeneutics of Science (Collegium Helveticum Heft 14) (Zürich, 2016), pp. 85-93.

In two recent papers, Michael Della Rocca accuses Descartes of reasoning circularly in the Fourth Meditation. This alleged new circle is distinct from, and more vicious than, the traditional Cartesian Circle arising in the Third Meditation. We explain Della Rocca’s reasons for this accusation, showing that his argument is invalid.

This article is intended as a contribution to the current debates about the relationship between politics and the philosophy of science in the Vienna Circle. I reconsider this issue by shifting the focus from philosophy of science as theory to philosophy of science as practice. From this perspective I take as a starting point the Vienna Circle’s scientific world-conception and emphasize its practical nature: I reinterpret its tenets as a set of recommendations that express the particular epistemological attitude (...) in which both the Vienna Circle’s (doing) philosophy of science and its political engagement were rooted. -/- Regarding politics, and referring to new primary sources, I reconstruct how the scientific world-conception placed the Vienna Circle within a neoliberal-socialist political network that pursued concrete political aims. In light of my reconstruction I shall argue that neither the Vienna Circle’s alleged ethical noncognitivism nor its alleged adhesion to the Weberian ideal of a value-free science rules out the possibility of ascribing to the Vienna Circle a politically engaged philosophy of science: the case of the Vienna Circle shows how philosophy of science, as a public activity, can itself become a form of political engagement, even without necessarily entailing a theory of objective values.

The apparently circular arguments in Descartes’s Meditations should be read as analytic arguments, as Descartes himself suggested. This both explains and excuses the appearance of circularity. Analysis “digs out” what is already present in the meditator’s mind but not yet “expressly known”. Once this is achieved, the meditator may take the result of analysis as an epistemic starting point independent of the original argument. That is, analytic arguments may be reversed to yield demonstrative proofs that follow an already worked-out order (...) of ideas. The “Cartesian Circle,” for example, is circular only when Descartes’s original analytic argument is mistaken for the demonstration that it enables. This approach to Cartesian Circles is unlike the standard approach, which attempts to show that Descartes’s original arguments do work as demonstrations after all. (shrink)

Hobbes repeatedly expressed concerns about moral and political language, e.g., about the bad consequences of various uses and misuses of language. He did not simply focus on the consequences though. He also attempted to understand the problems, using the central semantic notion in his philosophy of language, signification. Hobbes, in both the Elements of Law and Leviathan, argues that a wide variety of terms – including ‘good’, ‘bad’, and the names of virtues and vices – have a double and inconstant (...) signification. This paper explores and explains that theory of Hobbes's. (In the course of the discussion, two other interpretations of Hobbes's claims are discussed: Pettit’s discussion in terms of indexicals, and Alexandra’s in terms of sense and reference.) This phenomenon is, Hobbes thinks, pervasive in our use of moral and political language. Indeed he says his analysis applies to all “names of such things as affect us, that is, which please, and displease us” (Leviathan 4.24), which seems a very broad category indeed. This inconstancy of signification has considerable potential to cause confusion and conflict. Given those practical consequences, it is of some importance for Hobbes to find a solution to this problem. The paper examines several possible Hobbesian solutions to the problem. There is, however, reason to think that these suggested solutions cannot completely solve the problem. The paper concludes, then, by arguing that double and inconstant signification would always be a danger, even in a properly constituted Hobbesian commonwealth. (shrink)

What is attention? On one influential position, attention constitutively is the selection of some stimulus for coupling with a response. Wayne Wu has proposed a master argument for this position that relies on the claim that cognitive science commits to an empirical sufficient condition (ESC), according to which, if a subject S perceptually selects (or response-couples) X to guide performance of some experimental task T, she therein attends to X. In this paper I show that this claim about cognitive science (...) is false. Cognitive science allows for inattentive selection-for-task, or inattentive response-coupling. This means that Wu’s account is without independent support. (shrink)

Quoique l'on ne trouve qu'un nombre limité de références à Nicod dans les manuscrits de la période dite « intermédiaire » de Wittgenstein, une lecture attentive de La Géométrie dans le monde sensible s'avère pourtant décisive pour comprendre la nature du projet phénoménologique de Wittgenstein de la fin des années vingt. Nous nous proposons de montrer que la prise en compte ainsi que la reformulation du problème posé par Nicod en 1924, celui de la nature de la relation d'inclusion spatiale, (...) conduit Wittgenstein à remplacer dès 1929 l'ancien critère logique du simple et du complexe (celui du Tractatus logico-philosophicus) par un critère phénoménologico-grammatical inédit et désabsolutisé applicable à toute donnée visuelle quelle qu'elle soit. Plus généralement, la priorité donnée par Wittgenstein au visuel dans son « investigation phénoménologique des impressions sensorielles » trouve sa meilleure justification dans l'esquisse par Nicod d'une géométrie de la vision à la fois complète et indépendante. Nous montrons en particulier que les propriétés structurales du champ visuel mises au jour par Nicod dans sa construction (diversité et simultanéité des places sensibles, coloréité) sont tacitement utilisées par Wittgenstein pour justifier la possibilité d'une description phénoménologique conçue, précisément, comme description des places ou « localités » constitutives de cet espace perceptif.

Consequentialism is a state of affairs centered moral theory that finds support in state of affairs centered views of value, reason, action, and desire/preference. Together these views form a mutually reinforcing circle. I map an exit route out of this circle by distinguishing between two different senses in which actions can be understood as bringing about states of affairs. All actions, reasons, desires, and values involve bringing about in the first, deflationary sense, but only some appear to involve (...) bringing about in a second, rationalizing sense. I demonstrate that the views making up this circle hold, implausibly, that all reasons, values, desires, and actions involve bringing about in both senses, and that failure to distinguish these senses obscures the implausibility of these views as a set. I demonstrate, in addition, that the distinction blocks two common arguments that otherwise threaten to leverage us back in to the consequentialist circle. (shrink)

In this paper I attempt to trace some entanglements of an event documented in my PhD research, which contests dominant modes of enquiry. This research takes place with a group of Grade 2 learners in a government school in Cape Town, South Africa. It is experimental research which resists the human subject as the most important aspect of research, the only one with agency or intentionality. In particular, the analysis focuses on the process of the making of the circle, (...) and how integral it is in contributing to building the Community of Enquiry, the pedagogy of Philosophy with Children. A critical posthuman analysis is offered which engages with the material-discursive entanglements of the making of the circle. Also, how this making of a circle can be a democratising practice, by including in the concept of democracy, the more-than-human. The analysis also focuses on the placing of the chairs by the children, as a deliberate pedagogical practice, and how this works to disrupt the adult /child binary. There is a move beyond the linguistic turn by paying attention to not only the discursive in the transcriptions but also the intra-actions in between human and more-than-human, the circle, the chairs and the materiality of place.

What might it mean to say that there is such a thing as a hermeneutic circle in the social sciences? A consideration of some remarks by Charles Taylor and others and an interpretive reconstruction, and assessment, of the idea of such a circle.

How can a business institution function as an ethical institution within a wider system if the context of the wider system is inherently unethical? If the primary goal of an institution, no matter how ethical it sets out to be, is to function successfully within a market system, how can it reconcile making a profit and keeping its ethical goals intact? While it has been argued that some ethical businesses do exist, e.g., Johnson and Johnson, the argument I would like (...) to put forth is that no matter how ethical a business institution is, or how ethical its goals are, its capacity to act in an ethical manner is restricted by the wider system in which it must operate, the market system. Unless there is a fundamental change in the notion of the market system itself, the capacity for individual businesses to act in an ethical manner will always be restricted. My argument is divided into two parts. The first part is to show the inherent bias towards unethical outcomes that is inherent in the market system. The second part is to suggest how to reorient the general economic framework in order to make ethical institutions more possible. The question then becomes, how to define economic behavior in terms other than competition for profit. (shrink)

In theological sources, many symbols are used to explain the transcendent truths of existence. Among the shapes, the circle has the most use of a symbol which is important for Religious, philosophers, and mystics. However, what is refer mostly to the shape of a circle is the rotation of a circular line that begins at a point on a surface and ends at the same point; then, the most superficial and intermediate symbols of facts are explained with it. (...) Contrary, the present article proposes a novel way of drawing a circle, and with this approach, examines some philosophical concepts. We call this drawing "Boiling Circle", because, the rays are coming out boiling from the center. We also have analyzed and introduced a unique example of a mystical-philosophical-religious Architectural building, during which a circular spring has been built. Its water comes out boiling of the center and fills the five circles within itself and twelve eyes around it. This article begins with the drawing of a boiling circle, continues with explaining the philosophical symbols of the boiling circle and boiling spring according to Islamic mysticism, and ends with comparing and expressing the differences between the symbols of the two circles.

I consider recent strategies proposed by econometricians for extrapolating causal effects from experimental to target populations. I argue that these strategies fall prey to the extrapolator’s circle: they require so much knowledge about the target population that the causal effects to be extrapolated can be identified from information about the target alone. I then consider comparative process tracing as a potential remedy. Although specifically designed to evade the extrapolator’s circle, I argue that CPT is unlikely to facilitate extrapolation (...) in typical econometrics and evidence-based policy applications. To argue this, I offer a distinction between two kinds of extrapolation, attributive and predictive, the latter being prevalent in econometrics and evidence-based policy. I argue that CPT is not helpful for predictive extrapolation when using the kinds of evidence that econometricians and evidence-based policy researchers prefer. I suggest that econometricians may need to consider qualitative evidence to overcome this problem. (shrink)

Aristotle’s points about circle and vicious circle are as follows: 1. Aristotle criticizes some thinkers because ‘they see no difficulty in holding that all truths are demonstrated, on the ground that demonstration may be circular and reciprocal.’ (PsA., A, 3, 72b16-18) 2. ‘Not all knowledge is demonstrative’ and ‘knowledge of the immediate premises is independent of demonstration.’ Aristotle brings two reasons for this: ‘Since we must know the prior premises from which the demonstration is drawn, and since the (...) regress must end in immediate truths, those truths must be indemonstrable.’ (PsA., A, 3, 72b18-22) 3. Demonstration in the unqualified sense cannot be circular: ‘Demonstration must be based on premises prior to and better known than the conclusion; and the same things cannot simultaneously be both prior and posterior to one another: so circular demonstration is clearly not possible in the unqualified sense of demonstration, but only possible if ‘demonstration be extended to include that other method of argument which rests on a distinction between truths prior to us and truths without qualification prior, i.e. the method by which induction produces knowledge. But if we accept this extension of meaning, our definition of unqualified knowledge will prove faulty; for there seem to be two kinds of it. Perhaps, however, the second form of demonstration, that which proceeds from truths better known to us, is not demonstration in the unqualified sense of the term.’ (PsA., A, 3, 72b23-32) 4. The theory of circular demonstration ‘reduces to the mere statement that if a thing exists, then it does exist- an easy way of providing anything.’ (psA., A, 3, 72b32-34) 5. ‘To constitute the circle it makes no difference whether many terms or few or even only one is taken. Thus by direct proof, if A is, B must be; if B is, C must be; therefore, if A is, C must be. Since then- by the circular proof- if A is, B must be, and if B is, A must be. A may be substituted for C above. Then ‘if B is, A must be’ = ‘if B is, C must be.’ But C and A have been identified. Consequently, the upholders of circular demonstration are in the position of saying that if A is, A must be- a simple way of proving anything. Moreover, even such circular demonstration is impossible except in the case of attributes that imply one another, viz. ‘peculiar’ properties.’ (PsA, A, 3, 72b34-73a7) . (shrink)

Descartes has been accused of reasoning in a circle since the publication of the Meditations. The Circle is easy to point out: it seems that Descartes employs clear and distinct perceptions to demonstrate God’s existence and benevolence, and the latter, in turn, validates the use of clear and distinct perceptions. But is Descartes really guilty of fallacious argument, or can we break the arc somehow?

This paper attempts to demonstrate that the logical problematic of signification, has a very dangerous socio-political effect due to the ontological implication that is connected to the signification of terms in logic. It expounds the notion of signification in Formal Logic as exposed by William of Ockham. It thus, employs this notion of signification of terms, to discuss the term “Fulani”, to show the danger potent in distorting the signification of the term “Fulani” as in every conventional and connotative terms. (...) This work claims that as a result of the connection between logic and ontology, conceptualization and perception, names and reality, the distortion of terms, which are the building blocks of propositions in logic could lead to a dangerous cognition and perception of ontological realities. To this end, it posits a critique on the dangerous change in the signification of the term “Fulani”, in the conceptualization and perception of present day Nigeria people, of West Africa. A dangerous change, as this paper claims, if not speedily reconstructed and re-conceptualized, could lead to a disastrous situation in the socio-political reality of the Nigerian State. (shrink)

This chapter explores the opportunities and limitations of the ideal of transparency in responsible innovation, by consulting the virtual case of "The Circle", a company which appears in Dave Eggers' novel The Circle. The Circle is a high-tech company with the main purpose of being responsive to societal needs. They want to eradicate unethical behaviour in society, enhance public health and make a positive impact on the environment. The ultimate goal of The Circle is to reach (...) 100% full transparency in the world, which is impossible without any societal desirability. In first instance, it is free choice of people to accept and embrace the products and services of The Circle, who invest resources in keeping customers happy and in raising awareness about the dangers of privacy. The chapter concludes that The Circle meets the requirements regarding the outcomes of responsible innovation, at least to a certain extent, while at the same time, one feels unease about certain activities they undertake.

The Vienna Circle was an influential group of philosophers in the early 20th century. Its members were dedicated to do philosophy and to conduct research in accordance with the guidelines of the scientific world-conception. For some of them, Oswald Spengler was a dangerous antagonist due to the success and influence of his metaphysical philosophy of history in Der Untergang des Abendlandes and other works. In this paper, I will explore systematically the Circle’s critical reception of Spengler regarding his (...) methodological approaches, ontological positions, and political philosophy. I will, thereby, also evaluate the criticism brought forth against Spengler. (shrink)

The Berlin Group was an equal partner with the Vienna Circle as a school of scientific philosophy, albeit one that pursued an itinerary of its own. But while the latter presented its defining projects in readily discernible terms and became immediately popular, the Berlin Group, whose project was at least as sig-nificant as that of its Austrian counterpart, remained largely unrecognized. The task of this chapter is to distinguish the Berliners’ work from that of the Vienna Circle and (...) to bring to light its impact in the history of scientific philosophy. (shrink)

A. J. Ayer’s Language, Truth, and Logic had been responsible for introducing the Vienna Circle’s ideas, developed within a Germanophone framework, to an Anglophone readership. Inevitably, this migration from one context to another resulted in the alteration of some of the concepts being transmitted. Such alterations have served to facilitate a number of false impressions of Logical Empiricism from which recent scholarship still tries to recover. In this paper, I will attempt to point to the ways in which LTL (...) has helped to foster the various mistaken stereotypes about Logical Empiricism which were combined into the received view. I will begin by examining Ayer’s all too brief presentation of an Anglocentric lineage for his ideas. This lineage, as we shall see, simply omits the major 19th century Germanophone influences on the rise of analytic philosophy. The Germanophone ideas he presents are selectively introduced into an Anglophone context, and directed towards various concerns that arose within that context. I will focus on the differences between Carnap’s version of the overcoming of metaphysics, and Ayer’s reconfiguration into what he calls the elimination of metaphysics. Having discussed the above, I will very briefly outline the consequences that Ayer’s radicalisation of the Vienna Circle’s doctrines had on the subsequent Anglophone reception of Logical Empiricism.

This contribution aims at providing a more concrete and accurate understanding of Doughnut economics, its model, and its ideas. In doing so, it provides a comprehensive description of the Doughnut and its connection with the Sustainable Development Goals. Then, it inquires into the philosophical background of Doughnut economics, elucidating its existential rationale that relies on human dignity. Further, examples of four AI applications are used to showcase how the Doughnut model would address their use and challenges that arise thereof. From (...) this testing exercise transpires the understanding that another limitation is required in the Doughnut model, pursuant to its philosophical background. Therefore, besides economic activities that may breach the ecological ceiling or the social foundation, activities that infringe human dignity, without breaching any of the boundaries, are also incompatible with the Doughnut model. This complementing proposal is conceptually represented within the model of Doughnut economics. (shrink)

A widespread assumption in current philosophy of mind is that a conscious state’s phenomenal properties vary with its representational contents. In this paper, I present (rather dogmatically) an alternative picture that recognizes two kinds of phenomenal properties that do not vary concomitantly with content. First, it admits phenomenal properties that vary rather with attitude: what it is like for me to see rain is phenomenally different from what it is like for me to remember (indistinguishable) rain, which is different again (...) from what it is like for me to visualize (indistinguishable) rain – where these differences cannot be traced back to variations in content. Secondly, there is a kind of phenomenal property that varies neither with content nor with attitude but is altogether invariant across all conscious states: a substantive phenomenal commonality among what it is like for me to see, remember, and visualize rain, cats, or dogs. This substantive commonality, I will suggest, is the for-me-ness component of what it is like for me to have any of these experiences. I will close by discussing the interrelations among these three concentric layers of phenomenality: content-based, attitude-based, and for-me-ness. (shrink)

The hermeneutic circle serves as a standard argument for all those who raise a claim to the autonomy of the human sciences. The proponents of an alternative methodology for the human sciences present the hermeneutic circle either as an ontological problem or as a specific methodological problem in the social sciences and the humanities. This paper checks the soundness of the argument by sketching out three variations of the problem and critically discussing them.

Rhythm is generally taken to refer to a temporal pattern of events. Yet in recent years, across diverse fields in the arts, humanities, and social sciences, it has come to serve as the conceptual marker for a wide range of new approaches to understanding relations and relationality, following most explicitly from the late work of Henri Lefebvre. This article explores the temporal aspect of such relational thinking, in particular asking how time is implicated in relations, and how it can be (...) meaningful in those relations. The sense of time is surveyed from the perspectives of both cognition and metaphysics as well as with reference to music scholarship and social theory, and key threads are drawn, from the writings of Gaston Bachelard and Charles Sanders Peirce in particular, in order to suggest that time can be a sign, and that the signifying properties of rhythm have critical social consequences.

Judith Butler’s seminal book, Gender Trouble, categorizes drag performance as indicative example of gender performance. In it, they categorize drag performance along binary lines of gender “opposites”. I argue that Butler’s theory does not hold if the nuance inherent to drag performance is taken into consideration. In examining its complexity, I establish that the artform and its performers are politicized. Through this politicization, I explore how drag performers and drag performance are signified and are able to be understood hermeneutically as (...) a way to expand Butler’s initial theory. (shrink)

The traditional picture of the development of analytical philosophy, represented especially by such thinkers as G. Frege, G. E. Moore, B. Russell or R. Carnap, whose attitude was generally anti-metaphysical, can, on closer study, be shown to be incomplete. This article treats of the Cracow circle – a group of Polish philosophers among whom are, above all, to be counted J. Salamucha, J. M. Bocheński, J. F. Drewnowski, and B. Sobociński, who were, at the beginning of the twentieth century, (...) fascinated by the development of modern formal logic and its application to philosophical thinking. They also attempted to apply it to Catholic philosophy. The result of their endeavours were many remarkable works introducing not only a defence of the use of modern philosophical approaches in Christian thought, but also the reconstruction, by means of formal logic, of significant proofs given by Scholastic authors.

In 1682, Leibniz published an essay containing his solution to the classic problem of squaring the circle: the alternating converg-ing series that now bears his name. Yet his attempts to disseminate his quadrature results began seven years earlier and included four distinct approaches: the conventional (journal article), the grand (treatise), the impostrous (pseudepigraphia), and the extravagant (medals).

By examining oft-ignored writings, as well as unpublished manuscripts, this paper answers (...) the question of how one of the greatest mathematicians sought to introduce his first great geometrical discovery to the world.

Much contemporary political philosophy claims to be Kant-inspired, but its aims and method differ from Kant's own. In his recent book, Force and Freedom, Arthur Ripstein advocates a more orthodox Kantian outlook, presenting it as superior to dominant (Kant-inspired) views. The most striking feature of this outlook is its attempt to ground the whole of political morality in one right: the right to freedom, understood as the right to be independent of others’ choices. Is Ripstein's Kantian project successful? In this (...) research note I argue that it is not. First, I suggest that Ripstein's notion of freedom is viciously circular. It is meant to ground all rights, but in fact it presupposes an account of those rights. Second, I show that—independently of its inability to ground a whole political morality—such a moralized understanding of freedom is normatively unappealing. (shrink)

Epicurean ethics has been subject to withering ancient and contemporary criticism for the supposed irreconcilability of Epicurus’s emphatic endorsement of friendship and his equally clear and striking ethical egoism. Recently, Matthew Evans (2004) has suggested that the key to a plausible Epicurean response to these criticisms must begin by understanding why friendship is valuable for Epicurus. In the first section of this paper I develop Evans’ suggestion further. I argue that a shared conception of the human telos and of what (...) is required to attain it structures the confidence that characterizes friendship. In the second part of the paper I return to two contemporary criticisms of Epicurean friendship. The first criticism focuses on the problem of free riders. The second criticism points to a seeming inconsistency in Epicurean doctrine. I suggest that both criticisms can be adequately addressed once we understand Epicurean friendship in greater depth.

Discussions of the relation between pragmatism and logical empiricism tend to focus on the period when the logical empiricists found themselves in exile, mostly in the United States, and then attempt to gauge the actual extent of their convergence.

I argue for a substantially (...) qualified affirmative answer. (shrink)

An underappreciated fact in the history of analytic philosophy is that American pragmatism had an early and strong influence on the Vienna Circle. The path of that influence goes from Charles Peirce to Frank Ramsey to Ludwig Wittgenstein to Moritz Schlick. That path is traced in this paper, and along the way some standard understandings of Ramsey and Wittgenstein, especially, are radically altered.

A review of the recent exhibition of Wassily Kandinsky's artworks at the Guggenheim Museum, with interest in Kandinsky's career-wide separation of form from content.
