This review provides an overview of the ethics of extinctions with a focus on the Western analytical environmental ethics literature. It thereby gives special attention to the possible philosophical grounds for Michael Soulé’s assertion that the untimely ‘extinction of populations and species is bad’. Illustrating such debates in environmental ethics, the guiding question for this review concerns why – or when – anthropogenic extinctions are bad or wrong, which also includes the question of when that might not be the case (...) (i.e. which extinctions are even desirable). After providing an explanation of the disciplinary perspective taken (section “Introduction”), the concept of extinction and its history within that literature are introduced (section “Understanding extinction”). Then, in section “Why (or when) might anthropogenic extinctions be morally problematic?”, different reasons for why anthropogenic extinctions might be morally problematic are presented based on the loss of species’ value, harm to nonhuman individuals, the loss of valuable biological variety and duties to future generations. This section concludes by also considering cases where anthropogenic extinctions might be justified. Section “How to respond to extinctions?” then addresses a selection of topics concerning risks and de-extinction technologies. Finally, the section on “Extinction studies” introduces other viewpoints on the ethics of extinction from the extinction studies literature, followed by the “Conclusion”. (shrink)

Autonomy has been central to moral and political philosophy for millenia, and has been positioned as a critical aspect of both justice and wellbeing. Research in psychology supports this position, providing empirical evidence that autonomy is critical to motivation, personal growth and psychological wellness. Responsible AI will require an understanding of, and ability to effectively design for, human autonomy (rather than just machine autonomy) if it is to genuinely benefit humanity. Yet the effects on human autonomy of digital experiences are (...) neither straightforward nor consistent, and are complicated by commercial interests and tensions around compulsive overuse. This multi-layered reality requires an analysis that is itself multidimensional and that takes into account human experience at various levels of resolution. We borrow from HCI and psychological research to apply a model (“METUX”) that identifies six distinct spheres of technology experience. We demonstrate the value of the model for understanding human autonomy in a technology ethics context at multiple levels by applying it to the real-world case study of an AI-enhanced video recommender system. In the process we argue for the following three claims: 1) There are autonomy-related consequences to algorithms representing the interests of third parties, and they are not impartial and rational extensions of the self, as is often perceived; 2) Designing for autonomy is an ethical imperative critical to the future design of responsible AI; and 3) Autonomy-support must be analysed from at least six spheres of experience in order to approriately capture contradictory and downstream effects.

According to the brain drain argument, there are good reasons for states to limit the exit of their skilled workers (more specifically, healthcare workers), because of the negative impacts this type of migration has for other members of the community from which they migrate. Some theorists criticise this argument as illiberal, while others support it and ground a duty to stay of the skilled workers on rather vague concepts like patriotic virtue, or the legitimate expectations of their state and co-citizens. (...) In this article, on the contrary, we suggest that the liberal conception of states’ legitimate political authority demands, and not just permits, that developing states from which migration of skilled workers occurs set up contractual mechanisms. These mechanisms will ensure that state-funded training in the health sector is provided against a commitment on the part of future professionals to reciprocate with their services for the benefits obtained. If one of the conditions for the state to maintain legitimate political authority is to provide basic services such as healthcare to its subjects (while respecting at the same time their autonomy and freedom), then this is what developing states affected by the brain drain ought to do. What we call the authority-based approach to the brain drain also helps to clarify the obligations that other states have not to interfere with these contractual mechanisms when they exist, and not to profit from their absence. Inspired by FIFA’s legal instruments of training compensation and solidarity mechanism for the transfer of players, we conclude by suggesting a plausible global policy to complement this authority-based approach.

While anthropogenic species extinctions can be considered morally problematic for a range of reasons, they can also be described as a problem of interspecies justice. That is the focus of this paper in which we argue that human-caused species extinctions can be integrated within a non-anthropocentric account of reparative justice that is significantly similar to how reparation is understood within political theory at large. An account such as this faces a series of difficulties, such as how to make right past (...) injustices against victims that do not exist any longer and which belonged to species now extinct. For that purpose, we offer an argument in favour of symbolic forms of reparation in the form of, amongst other things, the preservation and restoration of habitat to materially repair the interspecies justice relationship; as well as monuments and education to honour the nonhuman dead.

A strange dialectical reversal characterizes the oppositions which psychoanalysis posits against philosophy and neuroscience: what psychoanalysis intervenes with as a unique and missing quality of these subjects, reveals itself upon enquiry as already having been a feature of said subjects. This article first discusses the failed intervention of psychoanalysis within the perceived totalities and absolutes of German idealism. Psychoanalysis, founded on an ontological division and internal inconsistency with a retroactive logic, finds this internal contradiction already reflected within the supposed totalities (...) of Schelling and Hegel. Schelling’s “blind act,” a decision with no prior foundation that grounds an abstract identity-in-itself, appears as the counterpart to what Badiou calls the strictly “analytic act.” Hegel’s Science of Logic, in which the inconclusive interpenetration of being and nothing presupposes its own conclusion in the transitions to essence, and in which an internal incompleteness and contradiction are retroactively constitutive of the concept, similarly nullifies the intervention of psychoanalysis. Finally, precisely such a reversal is presented in neuroscience, where the constitutive contradiction of contingently functional neuronal formations in the adaptive “multiple demand” model of executive functioning repeats the contingent and self-contradicting psychoanalytic subject as being its own deference within linguistic, discursive formations.

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

This is a short overview of Plato’s “greatest thing to be learned” or the “greatest lesson” (megiston mathêma) – the Idea of the Good.

We articulate a distinction between ontology, understood as involving existence questions, and metaphysics, understood as either providing for metaphysical profiles of entities or else as dealing with fundamentality and/or grounding and dependence questions. The distinction, we argue, allows a better understanding of the roles of metaontology and metametaphysics when it comes to discussing the relations between ontology and science on the one hand, and metaphysics and science on the other. We argue that while ontology, as understood in this paper, may (...) have reasonable perspectives for naturalization, given its relation to science, the same cannot be said for metaphysics, given that it is typically understood as an additional theoretical layer over science, not participating in the scientific investigation. That may result either in skepticism over metaphysics, or else on accepting that metaphysics is an autonomous branch of investigation, depending on one’s concern for metaphysics. (shrink)

Hegel insists that the category ‘nature’, expressed in relation to the ideal of aesthetic beauty, is not nature as such but a supplementary deviation coloured by the subjective position from which this ‘nature’ is posited. We cannot distinguish nature ‘in itself’ from the ideological-artistic conditions of the distorted ‘use’ of nature. Nature exists to us only by reference to what is subjectively treated as non-natural. A similar relation is posited by Lacan in his famous assertion that ‘there is no sexual (...) relation’. For Freud and Lacan, the ‘all too human’ sexual drive derives from a deviated/distorted enjoyment of the initial failure to enjoy a purely natural sexual relation: an inevitably castrated enjoyment, where ‘natural’ sexuality is revealed as impossible. In other words, sexuality is for Lacan and Freud its own distortion of the category of ‘natural’. Sexuality is a perpetually distorted and abnormal form of enjoyment, for which the alternative is not ‘normal/natural enjoyment’, but rather the negative state of a fundamental lack of any relation. Through Hegel and sexuality, this paper argues that the unavoidable misuse of nature is not caused by improper application/categorisation, but instead reflects an internal incompleteness or indeterminacy in nature as a category.

This paper deals with the deuteros plous, literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s Phaedo, the key passage being Phd. 99e4-100a3. I argue that (a) the ‘flight into the logoi’ can have two different interpretations, a standard one and a non-standard one. The issue is whether at 99e-100a Socrates means that both the student of erga and the student of logoi consider images (‘the standard interpretation’), or the student of logoi does not consider images but (...) that “consistency should suffice for truth” (‘the non-standard interpretation’); (b) the non-standard one implies the problem of the hypothesis, a problem analogous to the problem of the elenchus; (c) there is a structural analogy between Descartes’ ontological argument for the existence of God in his 5th Meditation and the final proof for the immortality of the soul in the Phaedo.

This article considers the historical tension in conceptualising Marx's materialism (dialectical and historical) as either a break from, or a fidelity to, Hegelian dialectics, and the methods by which this tension is itself subsumed under an insistence on vindicating the radical irreducibility of Marxist thought. Ultimately, however, it is argued that the question of whether Marx should or should not be framed alongside Hegel is the wrong question. It is not a question of 'Marx by himself' or 'Marx and... [Hegel]', (...) but rather of 'Marx without himself': as with any radical event in the history of ideas, it is a benefit to Marx's innovativeness that he can be retrospectively articulated according to historical traditions whilst simultaneously breaking from them. -/- .

The article tries to prove that the famous formula "epekeina tês ousias" has to be understood in the sense of being beyond being and not only in the sense of being beyond essence. We make hereby three points: first, since pure textual exegesis of 509b8–10 seems to lead to endless controversy, a formal proof for the metaontological interpretation could be helpful to settle the issue; we try to give such a proof. Second, we offer a corollary of the formal proof, (...) showing that not only self-predication of the form of the Good, but of any form is not possible, that is: no form of F has the form of F. Third, we apply Spinoza’s distinction between an ens imaginarium and a chimaera to Plato’s Idea of the Good. (shrink)

The debate over Plato’s “ so called unwritten doctrines”, which he communicated only to a small circle of trusted disciples, has caused a stir among philosophers in recent decades. Rafael Ferber assumes a differentiated position in this controversy. He is convinced that the unwritten doctrines did exist, but that Plato, for reasons inherent in the process of gaining knowledge, was unable to communicate these doctrines even to his closest disciples. In this book, Ferber outlines the discussion and summarizes the (...) standpoints of greatest interest. Ever since Aristotle, we have known that Plato did not put his most important teachings into writing, but instead communicated them only orally to the inner circle of his disciples. While the extant dialogues merely pass down Plato’s “exoteric” doctrines, his most important “esoteric” insights were not meant for the general public. In the meantime, the contents and the significance of Plato’s “unwritten doctrines” have become the subject of debate in philosophical circles. Fifteen years ago, at the height of the controversy over the “unwritten doctrines”, Rafael Ferber entered the fray with a small book. He proposed that Plato was also unable to communicate the “unwritten doctrines” because the highest principles (i.e. the subject of the unwritten doctrines) cannot be known through logical operations due to an epistemological paradox. Ferber’s differentiated position met with great respect and acceptance, although in individual cases it was also rejected. Ferber’s new book again presents the text of 1991, but significantly expands on it through new perspectives and an outline of the discussion it triggered. In this book, the reader learns what is meant by Plato’s unwritten doctrines and what the controversy is all about. (shrink)

This article asks the question “Why did Plato not write the ‘unwritten doctrine’?” and answers it by citing a combination of two obstacles. The first derives from the limitations of the episteme available to an embodied soul about the essence of the good. Even if the dialectician has access to some kind of knowledge, the mismatch between the unchanging essence of the good and the precarious logoi which aim to identify it (and allow others some measure of access to it) (...) can never fully be overcome. At best, Socrates (or Plato) can lead souls to an incomplete account of it: It is possible that even the most expert dialectician can only have a claim to knowledge, but no absolute certainty. Another obstacle lies in the audience or readership itself: No shortcut to understanding is possible, and yet a mere written presentation, which is all they have, is just such a shortcut, and so represents an empty promise. In memory of Charles H. Kahn (1928–2023), a letter of his from September 5, 1989, concerning the question “Why did Plato not write the ‘unwritten doctrine’?” is published, along with some comments.

In this paper two systems of AGM-like Paraconsistent Belief Revision are overviewed, both defined over Logics of Formal Inconsistency (LFIs) due to the possibility of defining a formal consistency operator within these logics. The AGM° system is strongly based on this operator and internalize the notion of formal consistency in the explicit constructions and postulates. Alternatively, the AGMp system uses the AGM-compliance of LFIs and thus assumes a wider notion of paraconsistency - not necessarily related to the notion of formal (...) consistency. (shrink)

In the whole Corpus Platonicum, we find in principle only one "direct argument" (Charles Kahn) for the existence of the ideas (Tim.51d3-51e6). The purpose of the article is to analyse this argument and to answer the question of why Plato in the Timaeus again defended the existence of the ideas despite the objections in the Parmenides. He defended it again because the latent presupposition of the apories in the Parmenides, the substantial view of sensibles, is removed through the introduction of (...) space as "substantialized extension". First (I) it is shown that Plato remained in dialogues, like the Sophist and Politicus, faithful to the "theory of ideas" despite his criticism in the Parmenides. The common theme in the trilogy of the Theaetetus, Sophist and Politicus is to refute relativism by showing that any relativism presupposes something absolute that is something like the "theory of ideas". The second part of the paper (II) examines closely the logical structure of the argument for the existence of ideas in the Timaeus (51d3-52a7). The third part (III) shows how this argument can avoid the criticism of ideas in the Parmenides. In the Parmenides, sensibles are treated as substantial entities. But, as the Timaeus shows, sensibles are not substantial entities but merely qualities, namely qualities of space, which is the only substance in the sensible world. A shortened English version of the paper appeared in Proceedings of the Fourth Symposium Platonicum, Granada, Selected papers, ed. by T. Calvo/L. Brisson, Academia Verlag, St. Augustin, 1997, 179-186. -/- But the only "direct argument" (Tim.51d3-51e6) seems to be interestingly flawed. Cf. Ferber, Rafael; Hiltbrunner, Thomas, (2005). (shrink)

A similar framing of inarticulable formations, of pure multiplicities, marks the respective projects of Deleuze and Laplanche. The absolute exteriority of a disjunctive multiplicity is re-inscribed as a relativised, interiorised trace. This trace-logic of Deleuze and Laplanche has definitive implications where the psychoanalytic subject and the unconscious is concerned. However, there is a difficulty in this logic of accounting for the unconscious formations enumerated by Freud (slips of the tongue, jokes, symptoms etc.). In turning to Lacan, however, the positions of (...) Deleuze and Laplanche can be illuminated (despite their attempt to ‘move beyond’ him). We see the trace in its material, unconscious substantiality upheld by the function of the big Other as an absent centre to which discourse is referred and through which the speaking subject is revealed as being in a discrepant relation to itself. The big Other, in his function as intimate, yet lacking, alterity, seems to help to resolve the problematic of multiplicity for Deleuze and Laplanche. (shrink)

The paper proposes (1.) a non-standard interpretation of the proverbial expression “deuteros plous” by giving a fresh look to Phaedo, 99c9-d1. Then (2.) it proceeds to the philosophical problem raised in this passage according to this interpretation, that is, the problem of the “hypothesis” or the “unproved principle”. It indicates finally (3.) the kernel of truth contained in the standard Interpretation and it concludes with some remarks on the “weakness of the logoi”.

The analysis of logical predication has long philosophical tradition in which one of the central subjects of study is the analysis of the logical form of the proposition. We contemporaneously can say that the way more well-finished of logic predication is propositional function. Historically, the propositional function arises as a logical analysis of the proposition scheme resulting from the convergence of mathematics and logic between the XIX and XX centuries. Two of the main responsible for this convergence were Gottlob Frege (...) (1848 - 1925) and Bertrand Russell (1872-1970). Influenced by Frege's ideas and direct heir of Russell, having been a disciple of this in Cambridge, Ludwig Wittgenstein (1889 - 1951) has become, in view of the originality of his thought, one of the most discussed and commented thinkers of the twentieth century, especially with the publication of his work entitled "Tractatus Logico-Philosophicus" (1921). It's in this work that Wittgenstein more considers himself debtor from Frege and Russell, having left explicit mention to them. Then the question that guides the development of this thesis is: what is the meaning of the propositional function of Frege and Russell in the Wittgenstein's Tractatus (1921)? Our goal is, in this sense, to investigate the meaning of the concept of propositional function in the Tractatus (1921). Our starting point is to understand the meaning of the propositional function in Frege and Russell to understand its meaning in the Tractatus (1921). We will focus our analysis on what Wittgenstein calls "propositional variable" (Satzvariable), term that best approximates, in our view, of the propositional function of Frege and Russell. In this sense, our interpretative question was formulated as: what is the meaning of the concept of propositional variable in the Tractatus (1921)? We defend the thesis that the role of the propositional function in Frege and Russell corresponds to the role of the propositional variable in Wittgenstein. (shrink)

Este artigo investiga alguns usos da metáfora da linguagem como cálculo em Wittgenstein. A metáfora do cálculo emerge, nos anos 30, numa interlocução com o referencialista, e é ali instrumental na recondução do olhar filosófico para os usos efetivos do simbolismo linguístico. Contudo, foi levada longe demais, ao sugerir uma imagem da linguagem composta apenas de inferências à maneira dos sistemas de regras fechados. Isto embargaria certa expansão pragmática do contexto criterial da análise conceitual. Mas a aplicabilidade do símile do (...) cálculo não é invalidada. A metáfora será reativada em manuscritos posteriores, sempre e quando puder servir aos mesmos propósitos do período intermediário, à medida que o ambiente dialógico convoque novas vozes dogmaticamente referencialistas. Ainda assim, é nos manuscritos intermediários que melhor se esclarece o seu funcionamento. Tal movimento exemplifica, por fim, um método filosófico que não procede por meio da superação de problemas à maneira científica. (shrink)

*Winner of the American Philosophical Association's 2020 Essay Prize in Latin American Thought* This essay offers a novel account of the secularity of Latin American liberation philosophy. It challenges the accepted notion that liberation philosophy applies the methods and approaches of Latin American liberation theology to the philosophical arena, thus putting liberation theology on secular grounds. While this formulation is true insofar as liberation philosophy is not bound by the hermeneutics of any particular religious tradition, this formulation could be misconstrued (...) given that liberation philosophy does not premise such secularization in an undialectical understanding of secularity as secularism that disavows religion. Rather, liberation philosophy’s secularity is dialectical in that it requires constant engagement with re-ligion, not in the hermeneutics of any specific tradition but with “the traditional question of the Absolute.” Due to this often-misunderstood element of liberation philosophy, it has frequently been “ghettoized and relegated to the ‘safe’ area of theological studies,” as Eduardo Mendieta argues. However, I contend that liberation philosophy’s secular grounds offer an original contribution to philosophy as a decolonial and postsecularist liberation philosophy, one that conceives of secularism as an aspect of coloniality to be overcome, an obstacle rather than a benefit for Latin American philosophers seeking to gain a better understanding of our historical conditions.

A Revisão de Crenças estuda como agentes racionais mudam suas crenças ao receberem novas informações. O sistema AGM, trabalho mais influente desta área apresentado por Alchourrón, Gärdenfos e Makinson, postula critérios de racionalidade para os diferentes tipos de mudança de crenças e oferece construções explícitas para tais - a equivalência entre os postulados e operações é chamado de teroema da representação. Trabalhos recentes mostram como o paradigma AGM pode ser compatível com diferentes lógicas não-clássicas, o que é chamado de AGM-compatibilidade (...) - este é o caso da família de lógicas paraconsistentes que analisamos, as Lógicas da Inconsistência Formal (LFIs, da sigla em inglês). A despeito da AGM-compatibilidade, ao se partir de uma nova lógica sua racionalidade subjacente deve ser entendida e sua linguagem deve ser efetivamente usada. Propomos assim novas construções que de fato capturam a intuição presente na LFIs - é o que chamamos de sistema AGMo. Com isso, possibilitamos a estas lógicas uma nova interpretação, na esteira da epistemologia formal. Em uma abordagem alternativa, ao se partir da AGM-compatibilidade os resultados AGM podem ser diretamente aplicados às LFIs - o que chamamos de sistema AGMp. Em ambas abordagens, provamos os respectivos teoremas da representação sempre que necessário. (shrink)

Reasons for action is a widely employed methodology in practical philosophy, and especially in moral philosophy. Reasons are facts that explain and justify actions. But, conceptually, if reasons were causes, incontinent actions would be impossible. When an agent ranks an evaluation about what to do as his best judgement, it entails that he has a reason for acting as that judgement prescribes. But when an agent acts incontinently, he acts in accordance to an intention that is not aligned with his (...) best evaluative judgement. Yet, if the agent’s best evaluative judgement provides him a reason for action, this reason should also be his strongest reason, and therefore, the strongest cause. How then can it be possible that an agent incontinently acts according to a reason of inferior causal strength? In this paper, I analyze how Davidson’s argument for the possibility of incontinent actions interacts with his causal theory of actions. I argue that Davidson’s proposal does not fully respect the two principles of intentional rationality, that he himself claims to be compelling. Lastly, I sketch some initial steps that might be helpful to drawing more precise conceptual distinctions in terms of the rationality of incontinent actions. (shrink)

The article first gives an exegesis of the famous passage in the "Republic", 505d11-506a2. Attention is drawn to the fact that the principle that every soul does everything for the Good can be translated in two ways: Every soul does everything for the sake of the Good, or goes to all lengths for the sake of the Good. Depending on the different translations, we have a different picture of the platonic Socrates in the Republic, an intellectualistic Socrates for whom irrational (...) desires do not exist, or a Socrates who also accepts irrational desires. The article favours the first one. Then it attempts to show that we can elucidate some dark points in the Socratic thesis that the Good is what every soul pursues and for which every soul does everything, with the help of Aquinas’s distinction between it actio hominis and actio humana. Finally, the article outlines three substantive answers to the question “What is the Good?” – the henological, the perfectionist and the structuralist. Instead of advancing a new answer, the article suggests an uncontroversial formal starting point for an answer to this question. (shrink)

Wittgenstein’s mature philosophy offers a therapeutic way out of some conundrums stemming from taxonomic expectations regarding philosophical description of experience in general. The paper asks if this is also true of the facts of aesthetic experience. This possibility is hinted at by examining an application of the notion of certainty to aesthetic experience. Some traits of possible uses of central concepts of the mature Wittgenstein to a philosophical aesthetics inspired by the “new method” are also canvassed.

The anthropologist James Frazer investigates the ritual gesture in search of be- liefs about the physical world by the native. Wittgenstein considers this a case of aspect- blindness, one that is disruptive of the conditions for understanding the native’s most triv- ial gestures. Unable to cast his glance from within the native situation, this methodological view from nowhere has an arresting effect on experience – in particular, the experience of speaking. This interruption is to be examined by means of a (...) thought experiment. Then, through the interplay of the concepts of Spirit and Aspect, a philosophical tool is described to assess the problem that can also serve as practical guide back to ordinary experience. The next step is to examine this way out in a particularly sensitive kind of experience of meaning: the aesthetic experience, also seen as a ritual. We conclude by alluding to a pos- sibly mutual illumination between aesthetic experience, translation studies and a Cavellian take on ordinary language. (shrink)

The article examines the Socratic principle that (1) virtue is knowledge and its corollary that (2) nobody errs voluntarily (nemo sua sponte peccat). It tries to show (I) that both principles are paradoxa, i.e. from a phenomenological point of view, they seem to be false; (II) that nevertheless the platonic Socrates accepts both principles as true; and finally (III) that these principles are analytical truths a priori which can only be understood if a person (soul) finds them in him- or (...) herself.

The paper deals with the "deuteros plous", literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s "Phaedo", the key passage being Phd. 99e4–100a3. The second voyage refers to what Plato’s Socrates calls his “flight into the logoi”. Elaborating on the subject, the author first (I) provides a non-standard interpretation of the passage in question, and then (II) outlines the philosophical problem that it seems to imply, and, finally, (III) tries to apply this philosophical problem to the "ultimate (...) final proof" of immortality and to draw an analogy with the ontological argument for the existence of God, as proposed by Descartes in his 5th "Meditation". The main points are as follows: (a) the “flight into the logoi” can have two different interpretations, a common one and an astonishing one, and (b) there is a structural analogy between Descartes’s ontological argument for the existence of God in his 5th "Meditation" and the "ultimate final proof" for the immortality of the soul in the "Phaedo".

In The moral problem (1994), Michael Smith tries to link three conflicting theories that alone are intuitively plausible, nevertheless, they do not seem to work well together. The first proposes that moral judgments are in fact beliefs about objective matters. The second states the concept of “practicality requirement”. The third is a humean belief-desire psychology, i.e. if a moral judgment is sufficient to explain actions, then it must involve a desire. If that is the case, it cannot be simply a (...) belief. For Smith, any attempt to solve the moral problem must find a way to hold all three doctrines. I will argue that his solution rests on two false assumptions. The first, a rationalist one which supports that what we have reason to do is what we would desire to do if we were fully rational. The second is the internalist thesis about moral motivation according to which a person who believes she is morally required to do something is either necessarily motivated to do it or she is practically irrational. I will base my critics on four objections raised by Copp, Miller, Shafer-Landau, Brink and Sayre-McCord. (shrink)

One core question in contemporary political economy is whether economic liberties should be constitutionally protected as basic rights. In this article I do not provide a positive argument for the view that economic liberties are basic rights. Rather, I seek to provide a reason for not embracing the opposing view, i.e. that economic liberties should not be constitutionally protected as basic rights. Based on Hayek’s theory of price as signal, I argue that price control, a view usually associated with high (...) liberals, and sometimes endorsed by moderate welfarists, is environmentally sub-optimal.

Schelling and Deleuze are polarised respectively as philosopher of identity and philosopher of difference par excellence. Schelling grounds reason in his early Naturphilosophie in the a priori identity deduced from the abstraction of the proposition A=A. Deleuze, however, reworks the Platonic Idea and Nietzsche’s Eternal Return in the service of an a priori ‘problematic being’, an ontological difference-in-itself, which precedes metaphysical identity. Despite their apparently polarised metaphysical groundwork, they stumble across a similar consequence: the distinction between subject and object, and (...) any problematic derived thereof, is in consequence of the ontological constitution of the object itself. The paradox of objectivity as indifference to an a priori difference or identity is presented, and preliminarily suggested to be due to the Deleuze-Schelling opposition not being a difference-identity opposition, but an opposition between difference and a ‘blind act’ which retroactively precedes the making-identical to itself of the one as distinguished from the many.

Plato scholars such as Matthias Baltes (1940-2003) and Luc Brisson have defended the thesis that Plato‘s Idea of the Good is on the one hand beyond being (epekeina tês ousias) in dignity and power, but is nevertheless not transcendent over being. The article gives first (I.), an introduction into the status questionis. Second (II.), it delivers the most important arguments for the thesis of Baltes and Brisson. Third (III.), it gives two counterarguments against the thesis. Fourth (IV), it deals with (...) the translation of L. Brisson "Apollon, quelle merveilleuse emphase" of 509c1-2. Fifth (V.), it concludes with some general questions concerning the deflationist interpetation of Plato‘s Republic, 509b9-10. (shrink)

La questione sulla verità del cristianesimo è fondamentale e ineludibile. In essa si trova uno dei filoni fondamentali del pensiero di Joseph Ratzinger – Benedetto XVI.

Nella visione cristiana ambedue non si contrappongono, ma s’incontrano. La “distinzione mosaica” s’incontra con la “distinzione socratica” . La pretesa di verità del cristianesimo conduce a (...) delle conseguenze sia nell’ambito della religione, sia in quello della filosofia e della morale. Per superare la crisi del cristianesimo abbiamo bisogno di recuperare la fiducia nela ragione e tornare alla ricerca della verità. (shrink)

In his Vermischte Bemerkungen 43, Wittgenstein notices that he was also influenced by Oswald Spengler. The paper deals with the question of in which way Spengler influenced Wittgenstein’s late works and if it really was influence or only a coincidence of ideas. It is put forward that Spengler’s rather unknown philosophy of language influenced Wittgenstein’s philosophy of language, especially the concepts of family resemblance, antiessentialism, and language-game (Sprachspiel). A picture of the famous Neapolitan gesture of “negation” which motivated Wittgenstein to (...) give up the picture theory of language is also shown with an example taken from Andrea de Jorio, La mimica degli antichi investigala nel gestire napoletano, Napoli 1832.

By Belief Revision it is understood a system that logically explains the rational process of changing beliefs by taking into account a new piece of information. The most influential approach in this field of study, the AGM system, proposed by Alchourrón, Gärdenfors, and Makinson, postulates rationality criteria for different types of belief change. In this paper I shall assess the relationship between those criteria and argue for an opposition between the principles of Information Economy and Consistency. Furthermore, I shall argue (...) that Paraconsistent Belief Revision manages to minimise this friction in the best possible way. (shrink)

Conceptual analysis is one of the notions undergoing dramatic changes during Wittgenstein's intermediate period. There's an aspect of such changes which might prove characteristic of the new directions taken by Wittgenstein's thought after 1929: it is the notion of complete analysis. We believe that Wittgenstein's treatment of this notion is also an interesting indication of new concerns generated by the "new method" itself, in terms of its radical openness to dialogism and its anti-dogmatism. Our aim here will be to explore (...) a couple of hints as to why this can be so. (shrink)

A mudança da concepção do critério geral da significação que tinha Wittgenstein no seu período intermediário para a concepção dos critérios de significação do seu período posterior justifica que se fale numa correlativa mudança na aplicabilidade do conceito de ‘uso’. Acompanhar esta mudança é importante para se caracterizar o âmbito do pragmático tal como Wittgenstein o concebe, e bem assim o tipo de investigação sobre os fundamentos do simbolismo linguístico e sobre a ligação entre linguagem e mundo que esse filósofo (...) advoga como adequada. Este artigo pretende circunscrever algumas das novas questões que, no período intermediário de Wittgenstein , conduziriam a tal mudança conceptual. (shrink)

The first part of the paper (p. 10-21) tries to answer the first question of the title and describes a set of seven “knowledge-claims” made by Socrates: 1. There is a distinction between right opinion and knowledge. 2. Virtue is knowledge. 3. Nobody willingly does wrong. 4. To do injustice is the greatest evil for the wrongdoer himself. 5. An even greater evil is if the wrongdoer is not punished. 6. The just person is happy; the unjust person is unhappy. (...) 7. The pleasant is not the good. These claims seem to be the “few” (oliga) (Men. 98 b3) but “very important” (kallista) (Grg. 472 c8) things that Socrates claims to know. The second part (p. 22-39) tries to answer the second question and defends the thesis that the supposed “knowledge” of Socrates is dianoetic, but not noetic. The main new idea of this paperis the comparison of the Socratic knowledge-claims with the upper states of the mind symbolized in theDivided Line, noesis and dianoia (cf. R. 511 d7-e1). Posted.

Revision operation is the consistent expansion of a theory by a new belief-representing sentence. We consider that in a paraconsistent setting this desideratum can be accomplished in at least three distinct ways: the output of a revision operation should be either non-trivial or non-contradictory (in general or relative to the new belief). In this paper those distinctions will be explored in the constructive level by showing how the remainder sets could be refined, capturing the key concepts of paraconsistency in a (...) dynamical scenario. These are preliminaries results of a wider project on Paraconsistent Belief Change conduced by the authors. (shrink)

As the intuitions about moral phenomenology shows the metaphysical distinction between mind-dependent and mind-independent properties has set the metaethical distinction between normativity and objectivity in ethics. Traditionally, many arguments were built in order to show that moral realists cannot account, in naturalist vocabulary, for the process of determining moral reference due to the desiderative disposition taken to be necessarily part of the meaning of moral terms. This dissertation assess some anti-realists arguments like is-ought thesis, the argument from queerness, the argument (...) from relativity and the open question argument. In what follows I propose the semantics elaborated by Cornell realism in order to address these arguments, especially the open question argument. However, as Moral Twin Earth test shows us the semantic proposed by Boyd is incomplete. Therefore I also evaluate a second attempt taken by Cornell realists such as Brink and Copp, based on Putnan's notion of referential intentions. (shrink)

The first chapter, "Der Hintergrund von Gadamers 'Phänomenologischen Interpretationen' in Sein und Zeit" traces the origins of Gadamer’s interpretation of the Philebus in Sein und Zeit. Especially important is that Dasein is, thanks to speech , already outside of itself in the world. The second chapter "Gadamers Dialektische Ethik" gives a short summary of the main points of Gadamer's interpretation of the Philebus. The third chapter "Davidsons reinterpretation of von Gadamer's Dialektischer Ethik" 222-231), points especially to the fact that Davidson (...) sees the "Socrates post Vlastos" in the interpretation of Gadamer at work: Because every man is already in possession of some basic truths, coherence is enough to lead to substantive truths. Davidson concludes that only in “interpersonal communication” "can be thought, a grasping of the fact of an objective, that is, a shared world". Thus, Davidson sees in Gadamer's interpretation of the Philebus his own theory of triangulation anticipated. (shrink)

The article is the revised version of an inaugural lecture given at the University of Lucerne on 8 November 2001. In part (I), I give an interpretation of the first sentence of the Aristotelian Metaphysics: ‘All men desire by nature to know’. In part (II), I show how, for Aristotle, this desire to know constitutes a continuum from knowledge given by sense perception to knowledge of the first principles. In part (III), I compare this Aristotelian conception to Plato’s more ‘existentialist’ (...) approach which implies the turning of a ‘whole soul’ rather than a continuum. Preferring the latter concep- tion, I conclude with some hints of what I plan to do in the next years and give a short overview of the history of universities in Europe and Switzerland, ending with the University of Lucerne.
