Abstract

I look at (I) the problem of false speech which Plato faces, (II) the solution he gives in the Sophist, and (III) how that very solution is undermined by the argument of the Theaetetus. I conclude that we ought to see the account of the Theaetetus as overruling the account of the Sophist. On this alternative, Plato holds that false speech and thought really is impossible.
