In his "Cratylus", Plato gives the etymology of Athena's name, the goddess of wisdom, from "Atheonóa" (Ἀθεονόα) meaning "god's ("theos") mind ("nous")". In his "Phaedo", Plato's teacher Socrates is made to say just before dying that his discovery of Anaxagoras' concept of a cosmic "nous" as the cause of the order of things, was an important turning point for him. But he also expressed disagreement with Anaxagoras' understanding of the implications of his own doctrine, because of Anaxagoras' materialist understanding of causation. Socrates said that Anaxagoras would "give voice and air and hearing and countless other things of the sort as causes for our talking with each other, and should fail to mention the real causes, which are, that the Athenians decided that it was best to condemn me". On the other hand, Socrates seems to suggest that he also failed to develop a fully satisfactory teleological and dualistic understanding of a mind of nature, whose aims represent the Good, which all parts of nature aim at.
