ABSTRACT At the centre of Plato’s Euthydemus lie a series of arguments in which Socrates’ interlocutors, the sophists Euthydemus and Dionysodorus propose a radical account of truth (‘chopped logos’) according to which there is no such thing as falsehood, and no such thing as disagreement (here ‘counter-saying’). This account of truth is not directly refutable; but in response Socrates offers a revised account of ‘saying’ focussed on the different aspects of the verb (perfect and imperfect) to give a rich account (...) of saying, of truth and of knowledge. I argue that Socrates’ response has much to offer, notably in its amplification of the process of saying and cognition, and the development of virtue. (shrink)
