Are the long, wildly inventive etymologies in Plato’s Cratylus just some kind of joke, or does Plato himself accept them? This standard question misses the most important feature of the etymologies: they are a competitive performance, an agôn by Socrates in which he shows that he can play the game of etymologists like Cratylus better than they can themselves. Such show-off performances are a recurrent feature of Platonic dialogue: they include Socrates’ speeches on eros in the Phaedrus, his rhetorical discourse in the Menexenus, and his literary interpretation in the Protagoras. The paper compares these cases to work out the ground rules, purposes and implications of the Platonic agôn, and the Cratylus etymologies in particular.

This paper explores in detail Gorgias' defense of rhetoric in Plato 's Gorgias, noting its connections to earlier and later texts such as Aristophanes' Clouds, Gorgias' Helen, Isocrates' Nicocles and Antidosis, and Aristotle's Rhetoric. The defense as Plato presents it is transparently inadequate; it reveals a deep inconsistency in Gorgias' conception of rhetoric and functions as a satirical precursor to his refutation by Socrates. Yet Gorgias' defense is appropriated, in a streamlined form, by later defenders of rhetoric such as Isocrates and Aristotle. They present it as an effective reductio against a critique of rhetoric that depends on the "harm criterion." This is puzzling, since Plato 's own critique of rhetoric does not depend on the harm criterion. On the other hand, Plato does seem to embrace the harm criterion as a more general principle—as if pre-emptively embracing the reductio —in his arguments about the good in the Meno and Euthydemus. Nonetheless, Isocrates and Aristotle seem to be deliberately misreading Plato on rhetoric: where he intends to criticize its intrinsic nature, they respond as if he were merely complaining about its contingent effects.

Simplicius’ project of harmonizing previous philosophers deserves to be taken seriously as both a philosophical and an interpretive project. Simplicius follows Aristotle himself in developing charitable interpretations of his predecessors: his distinctive project, in the Neoplatonic context, is the rehabilitation of the Presocratics (especially Parmenides, Anaxagoras and Empedocles) from a Platonic-Aristotelian perspective. Simplicius’ harmonizations involve hermeneutic techniques which are recognisably those of the serious historian of philosophy; and harmonization itself has a distinguished history as a constructive philosophical method.

A generally ignored feature of Aristotle’s famous function argument is its reliance on the claim that practitioners of the crafts (technai) have functions: but this claim does important work. Aristotle is pointing to the fact that we judge everyday rational agency and agents by norms which are independent of their contingent desires: a good doctor is not just one who happens to achieve his personal goals through his work. But, Aristotle argues, such norms can only be binding on individuals if human rational agency as such is governed by objective teleological norms..

The chapter discusses Plato’s oft-repeated assertion that all human desire is for the good. This claim is perplexing in a number of respects. For one thing, it seems to come in two forms, both of them apparently empirically false (and mutually incompatible): (1) all desire is for what the desiring agent views as good (‘the apparent good’) and (2) desire can only be for what really is good. The chapter argues that the thesis amounts to the claim that desire is realist or objectivist in orientation: In desiring, we attempt to respond appropriately to the detection of value in the world. Thus, without being vacuous (for it rules out many alternative conceptions of desire), Plato’s thesis sets no empirically refutable limitations on what objects may be desired. His point is rather that whatever is desired is desired on the basis of an evaluative belief. The tension between the two forms of the thesis is resolved by taking (2) as a clarification of (1), intended to make its realist import explicit: We desire ‘the apparent good’ not under that description, but simply in the sense that we pursue the real good as best we can detect it. The thesis is thus comparable to some epistemological arguments in the Sophist and Cratylus: Plato holds that a certain commitment to realism is built into our everyday cognitive practices, desiring included.

It is very difficult to get a clear picture of how the Stoic is supposed to deliberate. This paper considers a number of possible pictures, which cover such a wide range of options that some look Kantian and others utilitarian. Each has some textual support but is also unworkable in certain ways: there seem to be genuine and unresolved conflicts at the heart of Stoic ethics. And these are apparently due not to developmental changes within the school, but to the Stoics’ having adopted implicitly incompatible solutions in response to different philosophical challenges.
