This paper offers arguments against Francesco Ademollo’s redundancy thesis about the notion of the correctness of names in the Cratylus. The paper distinguishes between two versions of the redundancy thesis and provides arguments against each of them. In addition to supporting the rejection of both versions of the redundancy thesis, the arguments provide new interpretations of important issues inside and outside of the Cratylus. These issues include the philological evidence from the Classical period (e.g. Nicomachean Ethics, VI.9, 1142b6–12, on euboulia (...) as a kind of correctness), the view of correctness expressed by Plato’s Socrates in other dialogues, and Socrates’ initial discussion with Cratylus (in particular 428e–429b).
