The Sophist (Greek: Σοφιστής) is one of the late Dialogues of Plato, which was written much more lately than the Parmenides and the Theaetetus, probably in 360 BC. After he criticized his own Theory of Forms in the Parmenides, Plato proceeds in the Sophist with a new conception of the Forms, more mundane and down-to-earth, and makes clearer the epistemological and metaphysical puzzles of the Parmenides; therefore he is referring to that dialogue between Parmenides and young Socrates, which was written probably much earlier than the Sophist. Furthermore, he shows his expertise in Dialectic, as he applies it in this Dialogue in order to define the Sophist.
