This chapter discusses the first part of Aristotle's Posterior Analytics A-33, 88b30-89a10. I claim that Aristotle is not concerned with an epistemological distinction between knowledge and belief in general. He is rather making a contrast between scientific knowledge (which is equivalent to explanation by the primarily appropriate cause) and some explanatory beliefs that falls short of capturing the primarily appropriate cause.

This paper argues that Socrates does not claim to be a political expert at Gorgias 521d6-8, as many scholars say. Still, Socrates does claim a special grasp of true politics. His special grasp (i) results from divine dispensation; (ii) is coherent true belief about politics; and (iii) also is Socratic wisdom about his own epistemic shortcomings. This condition falls short of expertise in two ways: Socrates sometimes lacks fully determinate answers to political questions, and he does not grasp the first (...) principles of politics. (shrink)

One over Many: The Unitary Pluralism of Plato’s World is a tightly integrated collection of essays by the author, some newly drafted for the present work, some previously published as journal articles, all conceived and developed in pursuit of corrective intervention in Plato’s metaphysics. The book replaces the standard view of Plato as a metaphysical dualist with an alternative interpretation providing greater explanatory power through the paradigm of unitary pluralism in a single reality built on ontological diversity.

Desperately difficult texts inevitably elicit desperate hermeneutical measures. Aristotle's De Anima, book three, chapter five, is evidently one such text. At least since the time of Alexander of Aphrodisias, scholars have felt compelled to draw some remarkable conclusions regarding Aristotle's brief remarks in this passage regarding intellect. One such claim is that in chapter five, Aristotle introduces a second intellect, the so-called 'agent intellect', an intellect distinct from the 'passive intellect', the supposed focus of discussion up until this passage.1 This (...) view is a direct descendent of the view of Alexander himself, who identified the agent intellect with the divine intellect.2 Even the staunchest defender of such a view is typically at a loss to give a plausible explanation of why the divine intellect pops into and then out of the picture in the intense and closely argued discussion of the human intellect that goes from chapter four through to the end of chapter seven.3 Revolting against an extravagant postulation of entities, Michael Wedin, for example, has argued with considerable subtlety and ingenuity that there is in fact only one intellect discussed in De Anima.4 This unified intellect is fully capable of being integrated into Aristotle's hylomorphic psychology. In order to make his case, though, Wedin is himself forced (1) to discount the importance of some texts and (2) to interpret others in a way that strains credulity. (shrink)

This paper builds a dialectical system of explanation with speech act rules that define the kinds of moves allowed, like requesting and offering an explanation. Pre and post-condition rules for the speech acts determine when a particular speech act can be put forward as a move in the dialogue, and what type of move or moves must follow it. A successful explanation has been achieved when there has been a transfer of understanding from the party giving the explanation to the (...) party asking for it. The dialogue has an opening stage, an explanation stage and a closing stage. Whether a transfer of understanding has taken place is tested by a dialectical shift to an examination dialogue. (shrink)

_ Source: _Volume 60, Issue 1, pp 3 - 39 This paper pursues a new approach to the problem of the relation between Alētheia and Doxa. It investigates as interrelated matters Parmenides’ impetus for developing and including Doxa, his conception of the mortal epistemic agent in relation both to Doxa’s investigations and to those in Alētheia, and the relation between mortal and divine in his poem. Parmenides, it is argued, maintained that Doxastic cognition is an ineluctable and even appropriate aspect (...) of mortal life. The mortal agent, however, is nonetheless capable of sustaining the cognition of Alētheia by momentarily coming to think with—or as—his divine soul. (shrink)

The focus of this essay is on Xenophanes’ criticism of anthropomorphic representation of the gods, famously sounding like a declaration of war against a constituent part of the Greek religion, and adopting terms and a tone that are unequalled amongst “pre-Socratic” authors for their directness and explicitness. While the main features of Xenophanes’ polemic are well known thanks to some of the most studied fragments of the pre-Socratic tradition, a different line of enquiry from the usual one is attempted by (...) considering the multi-layered background of the religious beliefs revolving around the idea that the gods have human form as outlined in the tradition of epic poetry or represented in cult statues: in the light of this consideration Xenophanes’ text can take on some new characteristics. In the second part of the article, emphasis is put on the importance of the correlation Xenophanes established between the issue of the appearance of the gods and that of the certainty of knowledge, in terms that have exerted tremendous influence on later thought, most notably on Plato in the Timaeus.

> καὶ πῶς τις ἀνάξει αὐτοὺς εἰς φῶς, ὥσπερ > > ἐξ Ἅιδου λέγονται δή τινες εἰς θεοὺς ἀνελθεῖν; > > Plato Republic 521c This study reconstructs Empedocles’ eschatology and cosmology, arguing that they presuppose one another. Part one surveys body and soul in Empedocles and argues that the transmigrating daimon is a long-lived compound made of the elements air and fire. Part two shows that Empedocles situates our current life in Hades, then considers the testimonies concerning different cosmic levels (...) in Empedocles and compares them with the afterlife schemes in Pindar’s Second Olympian Ode and Plato’s Phaedo myth. Part three offers a new edition of section d lines 5–10 of the Strasbourg papyrus of Empedocles that reinforces the connection between transmigration and different cosmic locations for souls. Part four reconstructs Empedocles’ cosmology, identifies three different levels or habitats of soul, and, more tentatively, suggests that Empedoclean “long-lived gods” are best understood as stars.

This article offers a study of the early formation and development of the ideal of harmony in ancient Chinese philosophy and ancient Greek philosophy. It shows that, unlike the Pythagorean notion of harmony, which is primarily based on a linear progressive model with a pre-set order, the ancient Chinese concept of harmony is best understood as a comprehensive process of harmonization. It encompasses spatial as well as temporal dimensions, metaphysical as well as moral and aesthetical dimensions. It is a fundamentally (...) open notion in the sense that it does not aim to conform to any pre-set order. This broader, richer, and more liberal understanding of harmony has had a profound influence on Chinese culture as whole in its long history. (shrink)

Xenophanes of Colophon was a philosophically-minded poet who lived in various parts of the ancient Greek world during the late 6th and early 5th centuries BC. He is best remembered for a novel critique of anthropomorphism in religion, a partial advance toward monotheism, and some pioneering reflections on the conditions of knowledge. Many later writers, perhaps influenced by two brief characterizations of Xenophanes by Plato (Sophist 242c-d) and Aristotle (Metaphysics 986b18-27) identified him as the founder of Eleatic philosophy (the view (...) that despite appearances, what there is is a changeless, motionless, and eternal ‘one’. In fact, the Xenophanes who emerges from the surviving fragments defies simple classification. He was a traveling rhapsode who criticized the stories about the gods told by the poets, and he defended a novel conception of the divine nature. But he was also a reflective observer of the human condition, a practitioner of the special form of inquiry introduced by the Milesians philosopher-scientists, and a civic counselor who encouraged his fellow citizens to respect the gods and work to safeguard the well-being of their city.

According to current interpretations of Parmenides, he either embraces a token-monism of things, or a type-monism of the nature of each kind of thing, or a generous monism, accepting a token-monism of things of a specific type, necessary being. These interpretations share a common flaw: they fail to secure commensurability between Parmenides’ alētheia and doxa. We effect this by arguing that Parmenides champions a metaphysically refined form of material monism, a type-monism of things; that light and night are allomorphs of (...) what-is ; and that the key features of what-is are entailed by the theory of material monism.

The Evolutionary Synthesis is often seen as a unification process in evolutionary biology, one which provided this research area with a solid common theoretical foundation. As such, neo-Darwinism is believed to constitute from this time onward a single, coherent, and unified movement offering research guidelines for investigations. While this may be true if evolutionary biology is solely understood as centred around evolutionary mechanisms, an entirely different picture emerges once other aspects of the founding neo-Darwinists’ views are taken into consideration, aspects (...) potentially relevant to the elaboration of an evolutionary worldview: the tree of life, the ontological distinctions of the main cosmic entities , the inherent properties of self-organizing matter, evolutionary ethics, and so on. Profound tensions and inconsistencies are immediately revealed in the neo-Darwinian movement once this broader perspective is adopted. This pluralism is such that it is possible to identify at least three distinct and quasi-incommensurable epistemological/metaphysical frameworks as providing a proper foundation for neo-Darwinism. The analysis of the views of Theodosius Dobzhansky, Bernhard Rensch, and Ernst Mayr will illustrate this untenable pluralism, one which requires us to conceive of the neo-Darwinian research agenda as being conducted in more than one research programme or research tradition at the same time.

In this paper, I investigate how Xenophanes was ‘eleaticised’, i.e. attributed theses and arguments that belong to Parmenides and Melissus. I examine texts of Plato, Aristotle and Theophrastus in order to determine if they considered Xenophanes as a philosopher and a monist. I show that neither Plato nor Aristotle regarded him as a philosopher, but rather as a pantheist poet who claimed, in a vague way, that everything is one. But Theophrastus interpreted too literally Aristotle’s claims and was the first (...) to make Xenophanes a proper monist philosopher. (shrink)

This paper argues that the hypothesis proposed in the Meno is the proposition ‘virtue is good’ alone, and that its epistemic nature is essentially insecure. It has been an object of huge scholarly debate which other hypothesis Socrates posited with regard to the relationship between virtue and knowledge. This debate is, however, misleading in the sense of making us believe that the hypothesis that virtue is good is regarded as a truism in the light of the process of positing a (...) higher hypothesis described in the Phaedo and the Republic. I argue that the hypothesis in question is presented as a result of the earlier discussion of Meno's third definition of virtue, which implies the consequence that morally correct actions are beneficial whether or not accompanied by conventional goods such as wealth and honour. The underlying role of presenting it as a hypothesis is therefore to postpone demonstrating the truth of a controversial thesis which needs a substantial justification. In conclusion, I s...

Tem-se analisado, recorrentemente, a influência de Homero e de Hesíodo no proêmio do poema de Parmênides. As possíveis influências da poesia órfica tem sido apenas consideradas. Todavia, diversas descobertas de textos órficos aconselham voltar a analisar os vestígios da tradição mistérica, em geral, e órfica, em particular, no poema do filósofo de Eléia, sem minimizar, com isso, as outras influências já postas em relevo. O autor assinalou, em um trabalho anterior, algumas conexões entre Parmênides e os textos órficos; neste artigo, (...) a análise se centra nos pontos de contato com ideias e imagens literárias dos Mistérios que se encontram no proêmio. Não se trata de determinar as crenças do filósofo, senão de situar, no âmbito da tradição, os conteúdos doutrinais e/ou poéticos expressados nesta parte fundamental do seu poema, para fazer ver o que têm de poderosamente originais e, em consequência, tratar de determinar o significado do proêmio no conjunto da obra.

ArgumentThis article presents ancient documents on the subject of homeomeric lines. On the basis of such documents, the article reconstructs a definition of the notion as well as a proof of the result, which is left unproved in extant sources, that there are only three homeomeric lines: the straight line, the circumference, and the cylindrical helix. A point of particular historiographic interest is that homeomeric lines were the only class of lines defined directly as the extension of a mathematical property, (...) a move that is unparalleled in Greek mathematics. The far-reaching connections between mathematical homeomery and key issues in the ancient cosmological debate are extensively discussed here. An analysis of its relevance as a foundational theme will be presented in a companion paper in a future issue of Science in Context. (shrink)

En este artículo se discute la relación entre silogismo y demostración con respecto al concepto aristotélico del conocimiento científico formulado en los Analíticos segundos. La argumentación sigue tres líneas principales: (i) se ofrecen razones para rechazar la relegación de la sistematización silogística a la instancia postrera de justificación y exposición didáctica del conocimiento previamente adquirido. Como respuesta alternativa, (ii) se muestra que una explicación aristotélica necesita la silogística en virtud del papel que desempeña la causa como término medio silogístico. En (...) consecuencia, debería estar en condiciones de (iii) sostener que no resulta factible establecer firmemente los principios propios como premisas explicativas sin construir silogismos. This article focuses on the relation between syllogism and demonstration, as related to Aristotle's concept of scientific knowledge in his Posterior Analytics. Three main lines of argumentation are followed: (i) reasons are given to reject that syllogistic systematization plays a unique role as a skill for justification and didactic proof of a body of knowledge previously acquired. Alternatively, (ii) it is showed that an Aristotelian explanation requires syllogistic as to the role of cause as middle syllogistic term. Thus, it should be feasible (iii) to sustain that it is not possible to firmly establish proper principles as explanative premises without constructing syllogisms. (shrink)

This article questions the place of negative Forms in Plato’s ontology. And it does so against appearances to the contrary, given that Plato himself seems to acknowledge both positive Forms and negative Forms, that is to say, both good ones and bad ones. He may not say so outright, but he invokes both and rejects neither. The apparent finality of this impression is so strong that it creates a lack of direct interest in the subject: Plato scholars do not give (...) negative Forms much thought except where the prospect relates to something else they happen to be doing. Yet when they do give the matter any thought at all, typically for the sake of a prior concern, they try either to support the textual evidence or to contradict it, indicating that the evidence does not stand on its own. The aim of this article is to determine why they tend to affirm or deny the obvious, how they try to confirm or dispute it, and what this says about Plato’s position. The strategic vehicle is a comparative case study. The confirmation comes from Debra Nails (2013), who needs to embrace negative Forms to demonstrate that the unhypothetical first principle of everything is not identical to the Form of the Good, something she cannot do unless Plato recognizes negative Forms. The contradiction comes from Holger Thesleff (2013), who needs to reject negative (Ideal) Forms because the defining feature of his (Ideal) Forms is the possession of positive intrinsic value, which cannot be predicated of anything negative. Despite defending opposite views, or perhaps because of this, they jointly make up for any lack of interest in the scholarly community. I appreciate both yet side with Thesleff. (shrink)

Cicero, Lucullus 38: ‘…non potest animal ullum non adpetere id quod accommodatum ad naturam adpareat …’ From earliest childhood every man wants to possess something. One man collects horses. Another wants gold. Socrates has a passion for companions. He would rather have a good friend than a quail or a rooster. In this way, Socrates begins his interrogation of Menexenus. He then congratulates Menexenus and Lysis for each having what he himself still does not possess. How is it that one (...) gets a friend, Socrates asks? Since the nineteenth century many who have read these lines have found them repulsive. Scholars have damned the Lysis for its selfish egoism, for regarding persons as personal belongings. At the turn of the century some sought to discredit the dialogue as a forgery and a calumny. Others debated the dating of the dialogue as Socratic or Platonic, seeking whom to blame rather than whom to credit. And those who have regarded the dialogue as Platonic have tried to redeem it by detecting hints of Plato's theory of Forms. A few have attempted to salvage reputations by understanding the argument of the Lysis as a reductio of egoism, or else by invoking the loyalty of Socrates' friends and the history of Plato's friendship for Dion of Syracuse to speak up for their defence. Guthrie has condemned the dialogue as a failure of method and presentation , and Vlastos has pronounced it a failure of love: ‘The lover Socrates has in view seems positively incapable of loving others for their own sake, else why must he feel no affection for anyone whose good-producing qualities he did not happen to need?’ The Lysis appears to make no positive contribution to the Greek tradition on friendship when compared to the Symposium or the Phaedrus. And in the subsequent tradition, whatever Aristotle might have borrowed from the dialogue he uses for his own purposes. Aristotle too is quite critical of specific points raised in the Lysis. Now it might seem that Aristotle made a place for the selfish love of the Lysis in his own theory, as an inferior grade of utility love. But even this cannot be so, if we are to agree with recent studies of Aristotle's ethics. According to Aristotle, if a client is friendly to his benefactor because of the latter's usefulness, this utilitarian motive must accompany a genuine concern for the benefactor's own interest in that relation, if they are to be friends. Inferior and genuine friendship may differ in purpose but not in regard for the well-being of the beloved. This respect for the object of one's love has no parallel in the Lysis, according to the standard reading of the dialogue. (shrink)

Democritus is generally understood to have anticipated the seventeenthcentury distinction between primary and secondary qualities. I argue that this is not the case, and that instead for Democritus all sensible qualities are conventional.

There is an apparent tension in Laozi 老子 between his denial of the adequacy of positive theoretical formulations and his concomitant endorsement of certain kinds of practical action over others. Laozi writes, for example, “Where they all know the good as good, there is evil, Therefore Being and non-being produce each other” (Laozi 2.3–5), which suggests that good and evil produce each other the way being and non-being produce each other; in which case to do good will lead to evil (...) and to do evil will lead to good. The result threatens to become moral paralysis. I argue that this destabilization of moral concepts does not amount to a moral relativism, but leaves us with a consistent moral point of view in its own way. (shrink)

For many of the ancient Greek philosophers, the ethical life was understood to be closely tied up with important notions like rational integrity, self-control, self-sufficiency, and so on. Because of this, feeling or passion (pathos), and in particular, pleasure, was viewed with suspicion. There was a general insistence on drawing up a sharp contrast between a life of virtue on the one hand and one of pleasure on the other. While virtue was regarded as rational and as integral to advancing (...) one’s well-being or happiness and safeguarding one’s autonomy, pleasure was viewed as largely irrational and as something that usually undermines a life of reason, self-control and self-sufficiency. I want to try to show that the hedonist Aristippus of Cyrene, a student and contemporary of Socrates, was unique in not drawing up such a sharp contrast. Aristippus, I argue, might be seen to be challenging the conception of passion and pleasure connected to loss of self-control and hubristic behavior. Not only do I try to show that pleasure according to Aristippus is much more comprehensive or inclusive than it is usually taken to be, but that a certain kind of control and self-possession actually play an important part in his conception of pleasure and in his hedonism as a whole.

I argue that these inconsistencies in wording and practice reflect the existence of two distinct Aristotelian views of inquiry, one peculiar to the Posterior Analytics and the other put forward in the Physics and practiced in the Physics and in other treatises. Although the two views overlap to some degree (e.g. both regard a rudimentary understanding of the subject as an essential first stage), the view of the syllogism as the workhorse of scientific investigation and the related view of inquiry (...) as a search for the ‘missing middle terms’ turn out to be ideas peculiar to the Analytics. Conversely, the techniques of analysis and differentiation highlighted in the Physics account receive only cursory attention in the Analytics. However, when we consider the character of Aristotle’s own inquiries, on both scientific and philosophical topics, it becomes clear that it is the Physics rather than the Posterior Analytics that gives us Aristotle’s considered view the path to knowledge.

Can the physicalist consistently hold that representational content is all there is to sensory experience and yet that two perceivers could have inverted phenomenal spectra? Yes, if he holds that the phenomenal properties the inverts experience are dummy properties, not instantiated in the physical objects being perceived nor in the perceivers.

I advocate an ad hominem reading of the hedonism that appears in the final argument of the Protagoras. I that attribute hedonism both to the Many and to Protagoras, but my focus is on the latter. I argue that the Protagoras in various ways reflects Plato’s view that the sophist is an inevitable advocate for, and himself implicitly inclined toward, hedonism, and I show that the text aims through that characterization to undermine Protagoras’ status as an educator. One of my (...) objectives in the course of my arguments is to explore connections between the final argument of the Protagoras and the Man-Measure Doctrine as it is developed in the Theaetetus.

In Philolaus’ cosmology, the earth revolves around a central fire along with the other heavenly bodies, including a planet called the counter-earth which orbits below the earth. His theory can account for most astronomical phenomena. A common criticism of his theory since ancient times is that his counter-earth does no work in the system. Yet ancient sources say the planet was supposed to account for some lunar eclipses. A reconstruction of Philolaus’ cosmology shows how lunar eclipses occurring at certain times (...) of day cannot be explained by earth blocking the sun’s light. The counter-earth could explain these eclipses. (shrink)

Recent research on “psychotherapy” in Greek philosophy has not been fully integrated into thinking about philosophy as a way of life molded by personal relationships. This article focuses on how the enigma of Socratic eros sustains a network of thought experiments in the fourth century BCE about interpersonal dynamics and psychical transformation. It supplements existing work on Plato's Symposium and Phaedrus with comparative material from Aeschines of Sphettus, Xenophon, and the dubiously Platonic Alcibiades I and Theages. In order to select (...) and illuminate commonalities among all of these, it also draws critically upon Jacques Lacan's psychoanalytic technique and his numerous comparisons between Socrates and psychoanalysts. What emerges is a more complex and qualified but no less sincere appreciation for the ideal of reflective, cooperative aspiration toward Beauty portrayed in Plato's dialogues. (shrink)

Scholarship on Aristotle’s NICOMACHEAN ETHICS (hereafter “the Ethics”) flourishes in an almost unprecedented fashion. In the last ten years, universities in North America have produced on average over ten doctoral dissertations a year that discuss the practical philosophy that Aristotle espouses in his Nicomachean Ethics, Eudemian Ethics, and Politics. Since the beginning of the millennium there have been three new translations of the entire Ethics into English alone, several more that translate parts of the work into English and other modern (...) languages, and half a dozen collections of new articles discussing Aristotle’s Ethics. Such an outpouring of scholarship has produced an almost unmanageable wave of books, articles, and reviews. Through my topical bibliography, I seek to organize this wealth of scholarly writing so as to make it manageable both to scholars working across the disciplines of philosophy, classics, history, and politics, and to scholars pursuing theses on specific topics within the Ethics. The bibliography takes as its model and is much indebted to that compiled by Barnes, Schofield, and Sorabji in their Articles on Aristotle, Volume 2: Ethics and Politics (1977), which was further updated and incorporated into the complete bibliography to all of Aristotle’s writings in Barnes’s Cambridge Companion to Aristotle (1995). Although I have taken guidance from their model, my bibliography differs in one main respect. Whereas Barnes et al. were more selective and annotated their bibliography, I have been more comprehensive in my inclusion of items. I have sought to include all books and journal articles concerned with the Ethics written in English over the last 120 years; additionally, I have sought to include representative and central works of scholarship written on the Ethics in French, German, and Italian during the same period of time.

This study focuses on the origin of life as presented in the thought of Anaximander of Miletus but also points to some parallel motifs found in much later conceptions of both the pre-Darwinian German romantic science and post-Darwinian biology. According to Anaximander, life originated in the moisture associated with earth (mud). This moist environment hosted the first living creatures that later populated the dry land. In these descriptions, one can trace the earliest hints of the notion of environmental adaptation. The (...) origin of humans was seen as connected in some way with fish: ancient humans were supposed to have developed inside fish-like animals. Anaximander took into account changes in the development of living creatures (adaptations) and speculated on the origins of humans. Similar ideas are found also in the writings of much later, eighteenth and nineteenth century authors who were close to the tradition of German romantic science. We do not argue that these later concepts are in any way directly linked with those of the pre-Socratics, but they show surprising parallels in, e.g., the hypothesis that life originated in a moist environment or the supposition that human developed from fish-like ancestors. These transformations are seen as a consequence of timeless logic rather than as evolution in historical terms. Despite the accent on the origin of living things, both Anaximander and the later Naturphilosophen lack in their notions the element most characteristic of Darwin’s thought, that is, the emphasis on historicity and uniqueness of all that comes into being.

Any comprehensive interpretation of the "Theaetetus" has to provide answers to, among others, two very general questions concerning that dialogue: "What is Plato's relation to the problems faced in the "Theaetetus"?" and "What is the significance of the absence of the Forms from the discussion of the "Theaetetus", given their undoubted relevance to the topic of the dialogue, i.e. knowledge?" Predominantly, the answer given to the first question in the literature has been that the problems are those that Plato is (...) trying to tackle and the one to the second question, when it has been addressed at all, that the Forms are left out of the discussion because Plato no longer thought them relevant, either for having abandoned or seriously revised them, by the time of writing the "Theaetetus". In this study of the Wax Block and the Aviary models of judgment that occur in the second part of the "Theaetetus" as part of its discussion of the problem of false judgment, I argue that the problems faced there actually arise because of the neglect of Forms. The discussion of the second part is, I contend, carried out on a materialist ontology, an ontology assumed because it suits the definition of knowledge as true judgment which inaugurates that part of the dialogue, an ontology in no way subscribed to by Plato. The Wax Block is, I explain, a materialist model and fails in the case of judgments about numbers for treating them on a par with material subjects, ignoring their intelligible status. In particular, it fails to distinguish judging 5 and 7 to be 11 from judging 12 to be 11 because of its neglect of Forms; Plato would distinguish those judgments by distinguishing 5 and 7 from 12 with help from his part-whole analysis, to which the Forms are essential.

The purpose of this paper is to give an account and a rational reconstruction of the heuristic advice provided by Aristotle in the Topics and Prior Analytics in regard to the difficulty or ease of strategic planning in the context of a dialectical dialogue. The general idea is that a Questioner can foresee what his refutational syllogism would have to look like given the character of the thesis defended by the Answerer, and therefore plan accordingly. A rational reconstruction of this (...) advice will be attempted from three perspectives: strategic planning based on the acceptability of Answerer’s thesis, strategic planning based on the predicational form of the thesis, strategic planning based on the logical form of the thesis. In addition, we will provide an illustration of the potential of this heuristic advice as we apply it to the interpretation of a fragment from Plato, presuming that, in a similar way, a reading of this kind might be more generally applicable in the interpretation of the Platonic dialogues.

According to Hippolytus of Rome, Heraclitus claimed (on one plausible translation) that ‘The teacher of most people is Hesiod. They know (epistantai) he knows (eidenai) the most, he who did not know (ouk eginôsken) day and night; i.e. that they are one thing’ (DK 22 B57). The remark gives rise to three questions: (1) In what manner did Hesiod reveal his ignorance of the unity of day and night? (2) Why did Heraclitus use three different verbs for knowing when one (...) might have sufficed? And (3) How could Heraclitus have consistently asserted that most people know that Hesiod knows the most things while identifying one fundamental truth Hesiod failed to know? I argue that each of the verbs for knowing Heraclitus used in B57 (epistasthai, eidenai, and gignôskein) had a distinctive meaning, and that by using all three, he was able to consistently and accurately characterize the prevailing epistemological situation.

This paper examines al-Fārābī's logical thought within its Arabico-Islamic historical background and attempts to conceptualize what this background contributes to his logic. After a brief exposition of al-Fārābī's main problems and goals, I shall attempt to reformulate the formal structure of Arabic linguistics (AL) in terms of the ontological and formal characteristics that Arabic logic is built upon. Having discussed the competence of al-Fārābī in the history of AL, I will further propose three interrelated theses about al-Fārābī's logic, in terms (...) of which I will attempt to redefine it: the logico-linguistic conception, the project of logicization, and nuclear logic. The final question that will arise is how Aristotle's logic could be built upon AL, which has a nature contrary to logic. The present paper also contributes to examining our traditional research habits in Arabic studies. (shrink)

This paper explores the role the Panhellenic centers played in facilitating the circulation of wisdom in ancient Greece. It argues that there are substantial thematic overlaps among practitioners of wisdom , who are typically understood as belonging to different categories . By focusing on the presence of σοφοί at the Panhellenic centers in general, and Delphi in particular, we can acquire a more accurate picture of the particular expertise they possessed, and of the range of meanings the Greeks attributed to (...) the word σοφία. This approach seeks to challenge the conventional categories of modern scholarship and to offer a broader and more inclusive interpretive framework in its stead. One such thematic overlap is the way in which many σοφοί are described as exerting an almost uncanny, yet highly conventional ability to attract listeners and enchant them with their verbal performances. There is plenty of material to support the view that σοφοό, through tapping into the repository of σοφία that Delphi constituted and by aligning themselves with its authority, were seen as themselves being a conduit for a similar type of charismatic speech.

The symbolism introduced earlier provides a convenient vehicle for examining the status and consistency of Aristotle's three diverse justifications and for explaining how he means to avoid Protagorean relativism without embracing Platonic absolutism. When the variables ‘ x ’ and ‘ y ’ are allowed to range over the groups of free men in a given polis as well as over individual free men, the formula for the Aristotelian conception of justice expresses the major premiss of Aristotle's three justifications: (1) (...) (∀ x )(∀ y ) (P(x)·W(x)/P(y)·W(y)=V(T(x))/V(T(y)))Democracy is justified by adding a minor premiss to the effect that as a group the many ( m ) are superior (>) in virtue and wealth to the few best men ( f ): 85 (2 d ) (P(m) · W(m)) > (P(f) · W(f)) (3 d ) V(T(m))>V(T(f))Absolute kingship is justified when a godlike man ( g ) appears in a polis who is incommensurably superior (≫) in virtue and wealth to all the remaining free men ( r ): (2 k ) (P(g) · W(g)) ≫ (P(r) · W(r)) (3 k ) V(T(g)) ≫ V(T(r))True aristocracy requires a more complex justification, which was symbolized in Section 4. These justifications are compatible with each other since they apply to different situations. The polises where democracy and true aristocracy are justified contain no godlike men, and the polis in which democracy is justified differs from that in which true aristocracy is justified in containing a large group of free men who individually have little virtue ( Pol. III.11.1281b23-25, 1282a25-26). Each of the justifications is a valid deductive argument. Aristotle affirms the major premiss they share on the basis of a twofold appeal to nature. The principle of distributive justice, the concept as distinguished from the various conceptions of distributive justice, is itself according to nature ( Pol. VII.3.1325b7-10) and so too is one particular standard of worth, the standard of the best polis. Consequently, the question of the status of these three justifications, whether they are purely hypothetical or not, is a question about the minor premiss or premisses of each. In the case of the democratic premiss Aristotle's answer is straightforward: it is sometimes but not always true ( Pol. III.11.1281bl5-21). Hence the justification of democracy is not purely hypothetical. Nor is the justification of absolute kingship. The man who is “like a god among men” ( Pol. III.13.1284a10-11) would be a man of heroic virtue (see VII.14.1332bl6-27); and such a man, Aristotle says, is “rare” ( σπávιoη ) (not nonexistent) ( E.N. VII.1.1145a27-28). The minor premisses of the aristocratic argument describe a situation where all of the free men in a given polis have sufficient wealth for the exercise of the moral and intellectual virtues and where all of the older free men of the polis are men of practical wisdom. In the Politics Aristotle makes only the modest claim that such a situation is possible: It is not possible for the best constitution to come into being without appropriate equipment [that is, the appropriate quality and quantity of territory and of citizens and noncitizens]. Hence one must presuppose many things as one would wish them to be, though none of them must be impossible ( Pol. VII.4.1325b37-38; see also II.6.1265al7-18). But Aristotle appears to subscribe to the principle that every possibility is realized at some moment of time ( Top. 11.11.115bl7-18, Met. Θ.4.1047b3-6, N.2.1088b23-25). This principle together with the claim that the situation described is possible entails that the situation sometimes occurs. Thus even Aristotle's justification of true aristocracy is not purely hypothetical. The final question is Aristotle's way of avoiding Protagorean relativism without embracing Platonic absolutism. The relativist, along with everyone else ( E.N. V.3.1131a13-14, Pol. III.12.1282bl8), can accept the principle of distributive justice: Q(x)/Q(y) = V(T(x))/V(T(y)) And he can concede that particular instances of this principle, particular conceptions of justice, accurately describe the modes of distributing political authority that appear just to particular polises and to particular philosophers. What he denies is that there is any basis for ranking these various conceptions of justice or for singling one out as the best (Plato, Theaet. 172A-B). Aristotle, following in Plato's track ( Laws X.888D7-890D8), maintains against the relativist that nature provides such a basis. But he departs from Plato in his conception of nature. For Plato “the just by nature” ( τó ρυσει δίκ↑oν }) ( Rep. VI.501B2) is the Form of justice, an incorporeal entity ( Phdo. 65D4-5, Soph. 246B8) that exists beyond time and space ( Tim. 37C6-38C3, 51E6-52B2), whereas for Aristotle the sensible world is the realm of nature ( Met. A.1.1069a30-b2). Thus in appealing to nature Aristotle does not appeal to a transcendent standard. Nor does he appeal to his main criterion of the natural, namely, happening always or for the most part. Aristotle's theory of justice is anchored to nature by means of the polis described in Politics VII and VIII, and he regards this polis as natural because it fosters the true end of human life and because its social and political structure reflects the natural hierarchy of human beings and the natural stages of life. Thus the nature that Aristotle's theory of justice is ultimately founded on is human nature. (shrink)

The text of Sophist 237-9 is aporetic and shares with many other dialogues this structure: A question is asked and an answer, given in a single sentence, is reached and accepted by the interlocutor. The the interlocutor is examined further and his assent undermined. I argue that the Stranger does not share Theaetetus' perplexity and holds the rejected answer. I explain the Stranger's behavior by appealing to his pedagogy.

In his accounts of plant and animal generation Pierre Gassendi offers a mechanist story of how organisms create offspring to whom they pass on their traits. Development of the new organism is directed by a material “soul” or animula bearing ontogenetic information. Where reproduction is sexual, two sets of material semina and corresponding animulae meet and jointly determine the division, differentiation, and development of matter in the new organism. The determination of inherited traits requires a means of combining or choosing (...) among each parent's contributions, and towards this end, Gassendi outlines the nature of competition and dominance among animulae. Unlike his fellow mechanists, Gassendi can extend his mechanism to his heredity account, because his proposed vehicle for ontogenetic transmission is material. That proposal in turn relies on his atomist hypothesis. The relative uniformity of atoms allows animulae to operate equivalently across different modes of generation, spontaneous or otherwise. Further, his molecular model of atomic structures allows a material means of storing ontogenetic information received from the souls of parent organisms. These accounts—flawed and sketchy—unsurprisingly fail to specify how hereditary information might be borne physically, and in any case do not meet Gassendi's own empiricist standards. Yet this generation theory with pretensions to a materialist mechanism establishes Gassendi's firm commitment to a unity of the sciences through an atomist ontology that underlies all physical phenomena, including the organic.
