The basis of stoic determinism (a) : everything has a cause -- The basis of stoic determinism (b) : causation is necessitating -- The threat of external determination -- Reflection and responsibility -- The three compatibilist theories of Chrysippus -- Epictetus on responsibility for unreflective action.

This is a collective study, in nine new essays, of the close connection between theology and cosmology in Stoic philosophy.

In this paper, I explore the Presocratic antecedents of the Stoic theory of conflagration and argue that, even though three central theses of this theory have solid antecedents in Presocratic physics, the logical connection between them is a Stoic innovation. I label the Presocratics who hold these theses ‘Anaximandreans’ and include in this group Anaximander himself, Heraclitus and Diogenes of Apollonia, and reveal that Anaximenes, Democritus and Antiphon share with them central meteorological and cosmological assumptions.

Este artigo apresenta a teoria supervalorativista da vagueza e discute a objecção, que frequentemente lhe é dirigida, segundo a qual essa teoria não consegue dar conta do fenómeno da vagueza de ordem superior.

It is agreed by most scholars that the Stoics were compatibilists regarding the relation between responsibility and determinism. On this view, the Stoics depart from two other positions. Unlike some eliminative determinists — labelled in modern discussions “hard-determinists”, but already active in Antiquity — they assert that, despite determinism, there are things that “depend on us”, or are : things for which we are genuinely responsible and for which, therefore, we may justifiably be praised or blamed. But the Stoics also (...) depart from the libertarian or “anti-determinist” 2 a position championed by the Epicureans in the early Hellenistic period and by Alexander of Aphrodisias on behalf of the Peripatetics, towards the end of the second century AD. Unlike the libertarian, who agrees on the incompatibility alleged by the hard-determinist, but preserves responsibility by rejectin necessitation, the Stoics preserve both responsibility and necessitation.

The semantic paradoxes are a family of arguments – including the liar paradox, Curry’s paradox, Grelling’s paradox of heterologicality, Richard’s and Berry’s paradoxes of definability, and others – which have two things in common: first, they make an essential use of such semantic concepts as those of truth, satisfaction, reference, definition, etc.; second, they seem to be very good arguments until we see that their conclusions are contradictory or absurd. These arguments raise serious doubts concerning the coherence of the concepts (...) involved. This article will offer an introduction to some of the main theories that have been proposed to solve the paradoxes and avert those doubts. Included is also a brief history of the semantic paradoxes from Eubulides to Tarski and Curry. (shrink)

The ´, or world's con flagration, followed by the restoration of an identical world seems to go against the rationality of the Stoic god. The aim of this paper is to show that Cleanthes, the second head of the School, can avoid this paradox. According to Cleanthes, the con flagration is an inevitable side-effect of the necessary means used by god to sustain the world. Given that this side-effect is contrary to god's sustaining activity, but unavoidable, god's rationality requires the (...) restoration of an identical world once the con flagration subsides. The paper also deals with the relation between Cleanthes and other early Stoics on the topic of con flagration. In particular, Cleanthes' position seems to diff er from Chrysippus'. For in contrast with the Cleanthean god, who causes the con flagration as a side-effect only, the Chrysippean god, according to an in fluential interpretation put forward by Jaap Mansfeld, causes the con flagration as his ultimate cosmological goal.

In this article we will argue that given certain conditions for the evolution of bi- ological controllers, these will necessarily evolve in the direction of incorporating consciousness capabilities. We will also see what are the necessary mechanics for the provision of these capabilities and extrapolate this vision to the world of artifi- cial systems postulating seven design principles for conscious systems. This article was published in the journal Neural Networks special issue on brain and conscious- ness.

The present paper studies a family of Stoic proofs of the intelligence of the cosmos, i. e. of the thesis that the cosmos is intelligent in the strong sense that it is, as a whole, something that thinks. This family, ‘F2’, goes back to a proof, ‘XP’, found in Philebus 29a9–30 a8 and Xenophon Mem. 1.4.8. F2 infers the intelligence of the cosmos, as XP does, from the general idea that our intelligence proceeds from the cosmos, which is the ultimate (...) cause of why we are intelligent, and the further claim that, since this is so, the cosmos itself must be intelligent. They differ from one another, however, in how they account for. In this paper, I present a new reason for why the accounts are different, that complements those given by David Sedley in a recent and important study of Stoic cosmology. Based on the analogy between intelligence and the four elements, XP puts forward the idea that the intelligence currently present in us is a portion of cosmic intelligence that has separated from it at some point in the past, and that has travelled from the outside cosmos to us. In contrast, the theory used by F2 to explain the generation of human intelligence is grounded not in the notions of separation and locomotion, but in that of transmission of a state. As I argue in some detail, the separation-locomotion model and the transmission model are not only different from each other, but also logically independent from one another: in general terms, neither entails the other. This transmission model used by the Stoics in a proof of the intelligence of the cosmos, I submit, is a major innovation in ancient cosmological and metaphysical thinking. (shrink)

Most words in natural language are vague, that is to say, they lack sharp boundaries and, hence, they have (actual or potential) borderline cases, where the word in question neither definitely applies nor definitely fails to apply. Vagueness gives rise to paradoxes, the best known of which is the sorites (concerned with how many grains of sand are needed to make a heap). Besides offering a solution to such paradoxes, a theory of vagueness should systematically describe how the truth conditions (...) of sentences with vague terms are determined; and it should also define the right logical principles for reasoning with such sentences. This article offers an introduction to the main theories of vagueness and to the problems they have to face. (shrink)

El objetivo de este trabajo es, por una parte, ofrecer una nueva interpretación de la teoría estoica de los universales a la luz del debate entre nominalismo, conceptualismo y realismo, y, por otra, desentrañar un paralelismo entre el análisis propuesto por los estoicos de enunciados cuyo sujeto gramatical son términos genéricos, y el análisis propuesto por Russell de enunciados como "El actual rey de Francia es calvo". Al final del trabajo se estudian las bases metafísicas de la teoría estoica de (...) los universales y se señala una posible tensión en su interior. The aim of this paper is to offer a new interpretation of the Stoic theory of universals in the light of the debate between nominalism, conceptualism and realism, and to bring out a parallel between the analysis proposed by the Stoic Chrysippus of statements whose grammatical subject is a generic term, and the analysis developed by Russell of statements such as "The current King of France is bald". At the end of the paper, the metaphysical basis of the Stoic theory of universals is examined and a possible contradiction in it is brought out. (shrink)

Challenging the notion of theory as white and experience as black, Lewis Gordon here offers a philosophical portrait of the thought and life of the Martinican-turned-Algerian revolutionary psychiatrist and philosopher Frantz Fanon as an example of "living thought" against the legacies of colonialism and racism, and thereby shows the continued relevance and importance of his ideas.

In this paper, I argue that the cleavage between the theory of reference and the theory of meaning, which under the influence of Quine has dominated a large part of the philosophy of language of the last fifty years, is based on a misrepresentation of Tarski's achievement and on an overestimation of the scope and value of disquotation. In particular, I show that, if we accept Davidson's critique of disquotation, the same kind of reasons that Quine offered in opposition to (...) the Carnapian theory of meaning also apply, mutatis mutandis, to the Tarskian theory of reference.

Este trabajo discute la interpretación de Marcelo Boeri sobre el compatibilismo estoico; esto es, la tesis de que es compatible con el determinismo que rige al mundo natural el que podamos ser genuinamente responsables de nuestras acciones. Según Boeri, los estoicos intentaron conciliar las dos cosas abriendo un margen de indeterminación gracias al cual nuestras acciones no están sujetas a la necesidad que domina los demás fenómenos naturales. La discusión que se ofrece aquí se basa en un análisis del concepto (...) antiguo de lo que depende de nosotros y de los conceptos estoicos de determinismo y modalidad. /// This paper discusses Marcelo Boeri's interpretation of Stoic compatibilism, the thesis that natural determinism does not rule out that we can genuinely be responsible for our actions. According to Boeri, the Stoic hold that this is so because our actions are to a great extent free from determination. The discussion of this interpretation is based on an analysis of the ancient concept of what depends on us and of Stoic concepts of determinism and modality. (shrink)

Leading figures in ancient philosophy present nineteen original papers on three key themes in the work of Richard Sorabji. The papers dealing with Metaphysics range from Democritus to Numenius on basic questions about the structure and nature of reality: necessitation, properties, and time. The section on Soul includes one paper on the individuation of souls in Plato and five papers on Aristotle's and Aristotelian theories of cognition, with a special emphasis on perception. The section devoted to Ethics concentrates upon Stoicism (...) and the complex views the Stoics held on such topics as motivation, akrasia, oikeitsis, and the emotions. It also includes one paper on the influence of Greek ethics in Modern Philosophy. The volume also contains a fascinating "intellectual autobiography" by Sorabji himself, and a full Bibliography of his works. (shrink)

En este trabajo discuto el argumento de Crisipo a favor de la indestructibilidad del cosmos que aparece en Eusebio, Praeparatio Evangelica 15.18.1-3. Este argumento complementa al que aparece en Plutarco, De Stoicorum Repugnantiis1052C, pero descansa sobre una base distinta, a saber, la teoría de la disolución de los cuerpos complejos en los cuatro elementos y la teoría sobre cómo estos últimos se transforman los unos en los otros. Según veremos, existen antecedentes importantes de estas teorías en Anaxímenes y su teoría (...) del cambio. Al final, me ocupo de dos objeciones que los propios estoicos formularon en contra del argumento de Crisipo. (shrink)

This chapter discusses the theory of determinism put forward by the ancient Stoics and its theory for rational action and moral responsibility. The Stoic argument for determinism is presented in Section 1. Stoic determinism implies fatalism. The first problem, studied in Section 2, is whether it is rational to be motivated to do anything if one believes in fatalism. A second problem is that determinism seems to imply that everything people do is fully determined by external causes alone. This problem, (...) and the solution proposed by the Stoics, are studied in Section 3. A third problem, discussed in Section 4, is whether moral responsibility is compatible or incompatible with the possibility of alternate actions. The chapter discusses two objections raised by incompatibilists, which relate to the notion of agency and freedom from external force. The chapter briefly considers one possible counter‐objection to Chrysippus, the third head of the Stoic school. (shrink)

As the first book to analyze the work of Fanon as an existential-phenomenological of human sciences and liberation philosopher, Gordon deploys Fanon's work to illuminate how the "bad faith" of European science and civilization have philosophically stymied the project of liberation. Fanon's body of work serves as a critique of European science and society, and shows the ways in which the project of "truth" is compromised by Eurocentric artificially narrowed scope of humanity--a circumstance to which he refers as the crisis (...) of European Man. In his examination of the roots of this crisis, Gordon explores the problems of historical salvation and the dynamics of oppression, the motivation behind contemporary European obstruction of the advancement of a racially just world, the forms of anonymity that pervade racist theorizing and contribute to "seen invisibility," and the reasons behind the impossibility of a nonviolent transition from colonialism and neocolonialism to post colonialism.

Este artículo ofrece un análisis tentativo de los argumentos estoicos a favor de la racionalidad del cosmos agrupándolos en cuatro familias distintas e intentado rastrear sus antecedentes en Platón. La diferencia entre las familias radica en que los argumentos de cada una son lógicamente independientes de los de las otras. Los de las dos primeras descansan en la teleología estoica y en su teoría embriológica. Los de las otras dos, en cambio, recurren a ideas acerca de los componentes básicos del (...) cosmos y acerca de su estructura orgánica. Los antecedentes platónicos de estas familias de argumentos no se limitan a la cosmología de Platón, sino que se encuentran también en principios clave de su metafísica. (shrink)

The intellectual history of the last quarter of this century has been marked by the growing influence of Africana thought--an area of philosophy that focuses on issues raised by the struggle over ideas in African cultures and their hybrid forms in Europe, the Americas, and the Caribbean. Existentia Africana is an engaging and highly readable introduction to the field of Africana philosophy and will help to define this rapidly growing field. Lewis R. Gordon clearly explains Africana existential thought to a (...) general audience, covering a wide range of both classic and contemporary thinkers--from Douglass and DuBois to Fanon, Davis and Zack.

Title in English: "Being a certain way without being definitely that way: a problem for supervaluationism". I argue that the supervaluationist theory of vagueness, in its most common version, is committed to a thesis – viz., the incompatibility between being-F and not-being-definitely-F – which is doubtful, unjustified and in conflict with the definition of super-truth as truth in all admissible precisifications of a vague language.

Her Majesty's Children reveals not only a deeply personal account of the experience of racism but is also a revolutionary work that asks us to reconsider our ordinary practices and lives to recognize and resist the traces of a colonial age of racism that so many claim is only part of our past.

Science fiction has been an inexhaustible source for the creation of technoscientific imaginary that has marked certain historical periods and influenced the production of subjectivity. This imaginary evokes complex ontological, epistemological, political, social, environmental and existential questions on the present and the future. The aim of this study was to identify and characterize the cultural productions accessed by the public to form an opinion about the genetic manipulation of human beings. A survey about sources of information that influence opinions on (...) the genetic manipulation of human beings was applied to 360 medical students (70.8% female). Movies were the most commonly mentioned source of information, followed by books, documentaries, news programs, television series, informational videos, soap operas and videogames. Science fiction was the most frequent genre and dystopian views of the future of humanity predominated. (shrink)

In this chapter, the author presents and develops his views on the philosophy of action. One main theme is the problem of acrasia: how is it possible that a person sometimes acts freely and intentionally against his own better judgement? The author criticizes Donald Davidson’s solution to this problem for being unrealistic and exaggerating the rationality of the agent. He also presents his original way of reading Aristotle’s most famous text on this subject, in Ethica Nicomachea VII 3. The role (...) of desires and reasons in the motivation of action, the individuation of actions, and the possibility of mental causation are also discussed. (shrink)

In the first part of De Interpretatione 9, Aristotle introduces an argument for fatalism that he obviously does not subscribe to. Readers of the chapter wonder how Aristotle replies to that argument. In this paper I claim that the main basis of his reply is the principle of equimodality stated in 19a33 (“statements are true in the same way as the actual things are”). I defend that this principle should be interpreted in the most straightforward way, as saying that the (...) modality with which any statement is true is the same as the modality with which the actual things referred to in the statement are what they are. This entails that something is (or will be) necessarily such and such only if the statement saying that it is (or will be) such and such is necessarily true. By applying this principle to Aristotle’s distinction between two kinds of non-necessary things – those that happen as chance has it and those that happen for the most part (hôs epi to poly) in one way rather than another –, one should conclude that, because these things are contingent, statements about them can only be contingently true.

After introducing Fitch’s paradox of knowability and the knower paradox, the paper critically discusses the dialetheist unified solution to both problems that Beall and Priest have proposed. It is first argued that the dialetheist approach to the knower paradox can withstand the main objections against it, these being that the approach entails an understanding of negation that is intolerably weak and that it commits dialetheists to jointly accept and reject the same thing. The lesson of the knower paradox, according to (...) dialetheism, is that human knowledge is inconsistent. The paper also argues that this inconsistency has not been shown by dialetheists to be wide enough in its scope to justify their approach to Fitch’s problem. The connection between the two problems is superficial and therefore the proposed unified solution fails. (shrink)

This collection of new essays by an international group of scholars closely examine the works of Aristotle's Organon. The Organon is the general title given to the collection of Aristotle's logical works: Categories, De Interpretatione, Prior Analytics, Posterior Analytics, Topics and Sophistical Refutations. This extremely influential collection gave Aristotle the reputation of being the founder of logic, and has helped shaped the development of logic for over two millennia. The chapters in this volume cover topics pertaining to each of the (...) six works traditionally included in the Organon as well as its manuscript tradition. In addition, a comprehensive introduction by the editors discusses Aristotle and logic, the composition and order of the Organon, and the authenticity, title, and chronology of the treatises that make up these works New Essays on Aristotle's Organon offers a valuable insight into this collection for students and scholars working on Aristotle, the works of the Organon, or the philosophy of logic more broadly.

The aim of this paper is to present, in a clear and accessible way, Donald Davidson's anomalous monism. I stress that what distinguishes Davidson's monism from other identity theories of the mind is the conjunction of an identity thesis (viz. the thesis that every mental event is a physical event) with an anti-reductionist argument, according to which there are no strict psychophysical laws.
