What all contemporary so-called aristotelian realists have in common has been identified by David Armstrong as the principle of instantiation. This principle has been put forward in different versions, but all of them have the following simple consequence in common: uninstantiated universals do not exist. Such entities are for the lotus-eating Platonist to countenance, but not for any sort of moderate realist. I shall argue that this principle, in any guise, is not the best way to differentiate aristotelianism from Platonism. (...) In its place, I shall suggest that the best way to differentiate the two versions of realism from each other is by means of a far more powerful idea: naturalism. And the surprising conclusion given this means of differentiation will be that contrary to the usual proclamations, Platonism will be the more naturalistic theory, whereas aristotelianism will come to be seen for what it really is, namely, non-naturalistic.

The article resonates Plato's ideas on education and art. In the Apology, Socrates describes his life's mission of practicing philosophy as aimed at getting the Athenians to care for virtue; in the Gorgias, Plato claims that happiness depends entirely on education and justice; in the Protagoras and the Meno, he puzzles about whether virtue is teachable or how else it might be acquired; in the Phaedrus, he explains that teaching and persuading require knowledge of the soul and its powers, which (...) requires knowledge of what objects the soul may act on and be acted on by which, in turn, requires knowledge of nature. The article also looks at musical and gymnastic education's effects on the soul using images from metallurgy and dyeing wool, saying that prerational souls are “most malleable and take on any pattern one wishes to impress on them.”.

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.
