This celebratory Festschrift dedicated to Charles Kahn comprises some 23 articles by friends, former students and colleagues, many of whom first presented their papers at the international "Presocratics and Plato" Symposium in his honor. The conference was organized and sponsored by the HYELE Institute for Comparative Studies, Parmenides Publishing, and Starcom AG, with endorsements from the International Plato Society, and the Dean of the School of Arts and Sciences, University of Pennsylvania. While Kahn's work reaches far beyond the Presocratics and (...) Plato, it is in these subject areas that the distinction of his scholarship has come to be regarded as virtually unrivaled. The articles contributed to this volume are by some of the most renowned scholars working on these topics today, their breadth and depth bearing witness to his profound impact and influence on the discipline of Ancient Greek Philosophy._ Charles Kahn taught Classics and Philosophy at Columbia University from 1957 to 1965, and has since been teaching in the Philosophy Department of the University of Pennsylvania. He spent a year as Visiting Professor at the American School of Classical Studies in Athens, and had additional Visiting Fellowships at Balliol College, Oxford and Clare Hall, Cambridge, and a term as Visiting Professor at Harvard. He is the recipient of several prestigious research grants, from the American Council of Learned Societies, the National Endowment for the Humanities, and the Guggenheim Foundation. In 2000 he was elected Fellow of the National Academy of Arts and Sciences. He is the author of _Anaximander and the Origins of Greek Cosmology, The Verb “Be” in Ancient Greek, The Art and Thought of Heraclitus, Plato and the Socratic Dialogue, Pythagoras and the Pythagoreans, and Essays on Being_. His latest book,_Plato and the Post-Socratic Dialogue_, is forthcoming from Cambridge University Press. _ Contributors: Julia Annas Sarah Broadie Lesley Brown Tomás Calvo-Martínez Diskin Clay John M.

Philosophos Agonistes: Imagery and Moral Psychology in Plato's Republic RICHARD PATTERSON THE COMPETITIVE IMPULSE in its simplest, first and best expression -- be best and first in everything, as Peleus advised Achilles -- seems foreign to the spirit of philosophy for a number of reasons. The most important of these finds metaphorical expression in a "Pythagorean" gnome of uncertain provenance: "Life, said [Pythagoras], is like a festival; just as some come to the festival to compete, some to ply (...) their trade, but the best people come as spectators, so in life the slavish go hunting for fame or gain, the philosophers for the truth" . Plato's celebrated tripartite soul of the Republic provides a psychological underpinning for these observations about the festival crowd, and in particu- lar the distinction between the agonistes -- the competitor hunting victory and fame -- and the philosophical seeker after truth. Bk. IV distinguishes a reason- ing, a spirited, and an appetitive part or aspect of the soul, each having its own proper function and the three together providing a basis for Socrates' discus- sion of the virtues of wisdom, courage, sophrosyne, and justice. Bk. IX is explicit about all three parts having their own particular and natural pleasures and desires: the two lower parts, "spirit" and "appetite," appear respectively as lovers of victory and glory, on the one hand, and money, food, drink, and sex, on the other;..

Aristotle's Modal Logic, first published in 1995, presents an interpretation of Aristotle's logic by arguing that a proper understanding of the system depends on an appreciation of its connection to the metaphysics. Richard Patterson develops three striking theses in the book. First, there is a fundamental connection between Aristotle's logic of possibility and necessity, and his metaphysics, and that this connection extends far beyond the widely recognised tie to scientific demonstration and relates to the more basic distinction between (...) the essential and accidental properties of a subject. Second, Aristotle's views on modal logic depend in very significant ways on his metaphysics without entailing any sacrifice in rigour. Third, once one has grasped the nature of the relationship, one can understand better certain genuine difficulties in the system of logic and appreciate its strengths in terms of the purposes for which it was created.

Aristotle founds his modal syllogistic, like his plain syllogistic, on a small set of ?perfect? or obviously valid sylligisms. The rest he reduces to those, usually by means of modal conversion principles. These principles are open to more than one reading, however, and they are in fact invalid on one traditional reading (de re), valid on the other (de dicto). It is argued here that this way of framing the contrast is not Aristotelian, and that an interpretation involving modal copulae (...) allows us to see how these principles, and the modal system as a whole, are to be understood in light of close and precise connections to Aristotle's essentialist metaphysics.

The target article makes an impressive case that nested set operations (NS) facilitate probability computations by helping make clear the relevant natural frequency partitions; however, NS can also contribute to common errors. That NS constitute a general reasoning process is supported by their role in deductive, modal, causal, and other reasoning. That NS are solely a rule-based process is problematic.

Contrary to Vaesen's argument that humans are unique with respect to nine cognitive capacities essential for tool use, we suggest that although such cognitive processes contribute to variation in tool use, it does not follow that these capacities arenecessaryfor tool use, nor that tool use shaped cognition per se, given the available data in cognitive neuroscience and behavioral biology.
