Soon after its publication, _Readings in Ancient Greek Philosophy_ was hailed as the favorite to become _the 'standard' text for survey courses in ancient philosophy. Nothing on the market touches it for comprehensiveness, accuracy, and readability._* (*APA Newsletter on Teaching Philosophy). Fifteen years on, that prediction has been borne out, and the volume's preeminence as the leading anthology for the teaching of ancient philosophy still stands. The Fourth Edition features a completely revamped and expanded unit on the Presocratics and Sophists that draws on the wealth of new scholarship published on these fascinating thinkers over the past decade or more. At the core of this unit, as ever, are the fragments themselves--but now in thoroughly revised and, in some cases, new translations by Richard McKirahan and Patricia Curd, among them those of the recently published Derveni Papyrus.

This is an investigation of Aristotle's conception of accidental compounds (or "kooky objects," as Gareth Matthews has called them)—entities such as the pale man and the musical man. I begin with Matthews's pioneering work into kooky objects, and argue that they are not so far removed from our ordinary thinking as is commonly supposed. I go on to assess their utility in solving some familiar puzzles involving substitutivity in epistemic contexts, and compare the kooky object approach to more modern approaches involving the notion of referential opacity. I conclude by proposing that Aristotle provides an implicit role for kooky objects in such metaphysical contexts as the Categories and Metaphysics.

This is an examination of Aristotle's notion of an "accidental being" -- something intermediate between a substance and a property. An accidental being (sometimes called "accidental compound" or "kooky object") is an ephemeral object, typically the compound of a substance and a property, that exists for only as long as its components are united. I set out the role that accidental beings play in Aristotle's solutions to several philosophical problems. I also investigate the similarity between these beings and the individual non-substances of Aristotle's Categories. Finally, I propose that accidental beings can be assimilated into a more contemporary conceptual scheme as events -- the states or conditions that substances are in or undergo.

Quine, in an influential passage, characterizes a certain kind of metaphysical view as "Aristotelian essentialism." Recent work on Aristotle suggests that he may not have been an essentialist in Quine's sense. This paper examines the question whether, and to what extent, Aristotle is committed to the kind of essentialism Quine discusses. Various promising areas of Aristotle's thought (alteration vs. coming-to-be and passing-away, kath' hauto predication) are examined and found wanting as sources of essentialism. Instead, Aristotle is found to be committed to essentialism in the hylomorphic conception of substance featured in the late books of the Metaphysics, despite the superficially anti-essentialistic appearance of the conception of matter as the ultimate subject of predication. Essentialism is part and parcel of Aristotle's conception of substances as the basic individuals.

This is a survey of Aristotle's development of the concept of substance in the Categories and Book VII (Zeta) of the Metaphysics. We begin with the Categories conception of a primary substance as that which is not "in a subject" -- i.e., not ontologically dependent on anything else -- and also not "said of a subject" -- i.e., not predicated of any item beneath it in its categorial tree. This gives us the idea of primary substances as ontologically basic individuals, the fundamental subjects of predication and of change. We then examine the conception of substance in Metaphysics Zeta, where Aristotle is interested not just in the question of what the primary substances are, but in the question of what makes them substances, or, as he would put it, what the "substance OF something" is. The conception of substance that Aristotle ends up with seems (as has been frequently noted) to be threatened with inconsistency, in that Aristotle seems to want to maintain, simultaneously, that (i) substance is form, (ii) form is universal, and (iii) no universal is a substance. Two main approaches toward resolving this inconsistency are considered, and a sketch is provided of how one of these approaches might be fleshed out. On the line I propose, the substantial form of a material compound is predicated accidentally and universally of the matter of that compound, but it is not the substance of the matter of which it is predicated. Rather, it is the substance of itself; but since it is the cause of the compound's being essentially the kind of thing that it is, the substantial form is, in a derivative way, the substance of the compound as well.

The first major work in the history of philosophy to bear the title "Metaphysics" was the treatise by Aristotle that we have come to know by that name. But Aristotle himself did not use that title or even describe his field of study as 'metaphysics'; the name was evidently coined by the first century C.E. editor who assembled the treatise we know as Aristotle's Metaphysics out of various smaller selections of Aristotle's works. The title 'metaphysics' -- literally, 'after the Physics' -- very likely indicated the place the topics discussed therein were intended to occupy in the philosophical curriculum. They were to be studied after the treatises dealing with nature (ta phusika). In this entry, we discuss the ideas that are developed in Aristotle's treatise.

The central argument in the Euthyphro is the one Socrates advances against the definition of piety as "what all the gods love." The argument turns on establishing that a loved thing (philoumenon) is 1) a loved thing because it is loved (phileitai), not 2) loved because it is a loved thing. I suggest that this claim can be understood and found acceptable if we take "because" to be used equivocally in it. Despite the equivocation, Socrates' argument is valid, showing that Euthyphro cannot offer this definition consistently with his view that the gods have as a reason for loving pious things that they are pious things.

Aristotle takes up the topic of change (or coming-to-be and ceasing-to-be) in both the Physics and De Generatione et Corruptione. He distinguishes between simple coming-to-be (substantial change), as when something comes into existence, and qualified coming-to-be (accidental change), as when an already existing thing alters, or moves, or changes in some other way. But he also maintains a persistence principle: that in every change, whether simple or qualified, there is something that persists throughout the change. I examine the question of whether this principle threatens the viability of the distinction between substantial and accidental change by comparing what Aristotle has to say about it in the Physics with what he says in GC. In the process, I discuss several recent treatments of the topic as well as some conflicting views about the role, if any, of prime matter in Aristotle's account of substantial change.

Aristotle's claim in Metaphysics Z.6 that "each substance is the same as its essence" has long puzzled commentators. For it seems to conflict with two other Aristotelian theses: (1) primary substances are individuals (e.g., Socrates and Callias), and (2) essences are universals (e.g., Man and Horse). Three traditional solutions to this difficulty are considered and rejected. Instead, to make the Z.6 equation consistent with (1) and (2), I propose that it be interpreted to be making something other than a straightforward identity claim. Callias is the same as his essence in the sense that to be identical to Callias is to be the same man as Callias (where Man is the essence of Callias). In general, x is identical to y if, and only if, x and y are the same E (where E specifies the "what it is to be" for x, i.e., the essence of x). So each of Socrates and Callias is the same as his essence, and Man is that essence, but Socrates and Callias are not identical, for they are not the same man.

It is traditionally maintained that according to Aristotle, matter provides a principle of individuation. Objections of several sorts have been raised against this interpretation. One objection holds that for Aristotle it is form, rather than matter, that individuates. A more radical objection is that Aristotle does not propose any principle of individuation at all. Any adequate discussion of this issue must make clear precisely what problems such a principle is meant to address. This in turn requires that several important distinctions be observed: (1) principles of individuation vs. principles of unity; (2) metaphysical vs. epistemological principles; (3) synchronic vs. diachronic unity and individuation; numerical vs. qualitative identity. After examining the objections in the light of these distinctions, I conclude that the objections cannot be sustained, and that, with appropriate qualifications, the traditional interpretation gives us the right idea about Aristotle.
