Paraconsistency is the study of logical systems with a non-explosive negation such that a pair of contradictory formulas (with respect to such negation) does not necessarily imply triviality, discordant to what would be expected by contemporary logical orthodoxy. From a purely logical point of view, the significance of paraconsistency relies on the meticulous distinction between the general notions of contradictoriness and triviality of a theory—respectively, the fact that a given theory proves a proposition and its negation, and the fact that (...) a given theory proves any proposition (in the language of its underlying logic). Aside from this simple rationale, the formal techniques and approaches that meet the latter definitional requirement are manifold. Furthermore, it is not solely the logical-mathematical properties of such systems that are open to debate. Rather, there are several foundational and philosophical questions worth studying, including the very question about the nature of the contradictions allowed by paraconsistentists. This entry aims to advance a brief account of some distinct approaches to paraconsistency, providing a panorama on the development of paraconsistent logic. (shrink)

This is a revised 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)

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)

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)

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.

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)

El presente artículo tiene como objetivo determinar el fundamento teológico del concepto de soberanía propuesto por el jurista alemán Carl Schmitt. Según nuestra hipótesis, tal fundamento teológico se encuentra en la filosofía del pensador danés Søren Kierkegaard, quien, en diferentes obras, desarrolló los importantes conceptos de excepción, decisión y suspensión teleológica de la ética en relación a la experiencia religiosa de la repetición. Como veremos, tales conceptos forman parte del fundamento teológico de la famosa definición schmittiana de la soberanía: “soberano (...) es quien decide sobre el estado de excepción”, la cual define el decisionismo del jurista alemán. Así, por medio del concepto de decisión, extraído de la obra kierkegaardiana e introducido en la doctrina de la soberanía, Schmitt logra tres objetivos. Por un lado, no solo inicia la crítica al parlamentarismo liberal y al Estado burgués de Derecho, sino que revela el fundamento teológico-existencial de la unidad política del Estado moderno. En segundo lugar, en el marco jurídico-político, actualiza la teología fideísta desarrollada por Kierkegaard en su obra. Finalmente, en el marco teológico-metafísico, introduce el papel de la decisión como actualizador del rol público de la trascendencia en la modernidad secularizada frente a la reserva escatológica de la teología. Para lograr nuestro objetivo, utilizaremos el método de la analogía conceptual teológico-política creado y aplicado por el mismo Carl Schmitt a la historia de la soberanía europea. (shrink)

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)

At the centre of the monograph (1984, first edition) lies a detailed interpretation and critique of the idea of the Good in the Republic. The main thesis of the interpretation runs as follows: The idea of the Good functions as a third item between thinking and being. The main purpose of the monograph is to introduce the systematic problem of the third item via the historical problem of the idea of the Good. The second, enlarged edition (1989) gives a new (...) reconstruction of an "exasperatingly difficult but ever fascinating topic" (H. Cherniss), that is, of the platonic theory of the ideal numbers and the two principles that were contained in the “so-called unwritten doctrines” (Aristotle). The final chapter gives new information on the reception of Plato's idea of the Good in P. Natorp and M. Heidegger. It also includes an updated bibliography.

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)

The beginning for C. S. Peirce was the reduction of the traditional categories in a list composed of a fundamental triad: quality, respect and representation. Thus, these three would be named as Firstness, Secondness and Thirdness, as well given the ability to degeneration. Here we show how this degeneration categorical is related to mathematical revolution which Peirce family, especially his father Benjamin Peirce, took part: the advent of quaternions by William Rowan Hamilton, a number system that extends the complex numbers, (...) i.e. those numbers which consists of an imaginary unit built by the square root of minus one. This is a debate that can, and should, have contributions that take into account the role that mathematical analysis and linear algebra had in C. S. Peirce’s past. (shrink)

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 proposes a general strategy to overcome normative conflicts, namely, paradoxes represented in Standard Deontic Logic. This solution is based on preference relations between norms that circumvent situations of conflict. Pragmatic justifications of the proposed method are also given.

*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.

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 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 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)

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)

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.

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 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".

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)

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.

Nosso objetivo neste trabalho é apresentar uma proposta de solução a paradoxos relacionados à lógica deôntica presentes na literatura, reunidos sob o que é chamado de dilemas deônticos - situações nas quais duas obrigações conflitantes estão presentes num mesmo sistema normativo.

Nossa proposta baseia-se em relações de preferência que geram uma ferramenta de escolha dentre as duas soluções normativas conflitantes, (...) o que evita a inconsistência e permite o pleno cumprimento do sistema.

Para ilustrar estas dificuldades, abordaremos as propostas de Carlos Alchourrón em artigo de 1975, “Condicionalidad y la representación de las normas jurídicas”. (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.

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)

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.

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)

Despite the fact that Aristotle and Frege/Russell differ in how to understand the ambiguity in the meaning of the word "is", their theories share a common feature: "is" does not have a normative meaning, but a constative meaning. This paper, however, shows (1) that there is a normative meaning of "is" (and correspondingly a constative meaning of the word "ought") and (2) that the ambiguity of "is" is itself ambiguous. Furthermore, the paper proposes (3) a performative criterion for making a (...) distinction between constative and normative "is". Thereby, it is possible to attack Searle's famous argument against Hume's law. (shrink)

La finalidad del presente artículo es descubrir la presencia del concepto de persona en la doctrina de la soberanía de Carl Schmitt. A pesar de que este concepto tuvo un amplio desarrollo metafísico en el seno del pensamiento cristiano durante la antigüedad tardía, jamás pudo desembarazarse de la impronta jurídica de sus creadores los juristas romanos. Por tal razón, sirvió como soporte conceptual para el posterior despliegue de la noción de persona jurídica, sistematizada a lo largo de la modernidad. Para (...) lograr nuestro objetivo, intentaremos rastrear la transformación del concepto de persona a lo largo de la edad media y la modernidad, así como revisar el concepto de soberanía en la teoría política moderna. Por otro lado, estudiaremos la noción de decisión en la obra de Carl Schmitt, noción que el gran jurista alemán utilizó para definir su propia concepción de la soberanía. A partir de estas precisiones, intentaremos establecer la relación existente entre la noción de persona y la de decisión en el seno de la concepción schmittiana de la soberanía tomando como hilo conductor los presupuestos teológicos implícitos en ella. Como veremos, tales presupuestos nos remitirán a la obra del pensador danés Søren Kierkegaard, cuyas doctrinas nos mostrarán todo el alcance del planteamiento schmittiano. De esta manera, podemos concluir que el concepto de persona subyacente al decisionismo schmittiano ha sido transformado, en primer término, en el de existencia política, noción determinada por la relación de enemistad; y, en segundo lugar, en el de unidad de la personalidad, concepto determinado por la actualización de la dimensión espiritual al interior de la condición humana.

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.

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.

The paper gives (I) a short introduction to Aristotle’s theory of the soul in distinction to Plato’s and tries again (II) to answer the question of whether the individual or the general active mind of human beings is immortal by interpreting “When separated (χωρισθεìς)” (de An. III, 5, 430a22) as the decisive argument for the latter view. This strategy of limiting the question has the advantage of avoiding the probably undecidable question of whether this active νοῦς is human or divine. (...) The paper closes with an outlook (III) on the Christian belief in the resurrection of body and soul in a spiritual body (σῶμα πνευματικóν) (1 Corinthians: 15, 44) by accentuating the ethical aspect of the belief in individual immortality as a “need of reason” (Vernunftbedürfnis) (Kant, Critique of Practical Reason, A 256–258).

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)

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

Since 1976, when Thomas A. Szlezák held his inaugural lecture as a private lecturer at the University of Zurich entitled "The Dialogue Form and Esotericism: On the Interpretation of the Platonic Dialogue the Phaedrus", the now-emeritus professor at Tübingen has advocated a particular interpretation of the Platonic dialogues and especially of the Phaedrus: namely, that what is referred to in the latter dialogue—without further explanation—as "more valuable" than what is set down in writing corresponds to Plato's "so called unwritten doctrines", (...) or for Szlezák, "unwritten...

The article first (i) 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 (panta prattei) 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 pure irrational desires do not exist, or a Socrates who also accepts irrational desires. The article favours the first picture. Then it (ii) attempts to show that we can elucidate two 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. Finally, the article (iii) outlines three substantive answers to the question ``What is the Good?'' - the henological, the perfectionist and the structuralist - and shows that these three answers lead into a trilemma. Instead of advancing a new answer, the article suggests an uncontroversial formal starting point for an answer to this question. (shrink)

The article again treats the question of whether ≪the Idea of the Good is a Reality in the Universe, or beyond it. Is it immanent or transcendent?≫. Plato scholars such as Matthias Baltes and Luc Brisson have defended the thesis that Plato’s Idea of the Good is, on the one hand, beyond being in dignity and power, but, on the other, is nevertheless not transcendent over being. The article delivers first the most important arguments for the thesis of Baltes and (...) Brisson. Then, it gives two counterarguments against the thesis. Third, it concludes with some general questions concerning the deflationist interpretation of Plato’s Republic 509b9‑10, and defends again the transcendence of the Idea of the Good. (shrink)

What distinguishes the Socrates of the early from the Socrates of the middle dialogues? According to a well-known opinion, the “dividing line” lies in the difference between the Socratic and the Platonic theory of action. Whereas for the Platonic Socrates of the early dialogues, all desires are good-dependent, for the Platonic Socrates of the middle dialogues, there are good-independent desires. The paper argues first that this “dividing line” is blurred in the "Symposium", and second that we have in the "Symposium" (...) a more distinctive dividing line, namely the introduction of the separate existence of the idea of beauty. This introduction by Diotima/Plato of separate ideas and the lack of understanding of separate ideas – here the idea of beauty – by Socrates may have been the limit not only of the Socrates of the early Platonic dialogues, but of the historical Socrates as well.
