Lecture notes for a course. As described in the New School course catalog, in this dialogue a student of Parmenides attempts to determine the being of Socrates in relation, on the one hand, to the contemporary sophist and, on the other, to all the philosophers prior to Socrates. Socrates' life on the marketplace looks like a marketing of philosophy and not at all like the speculative practice of the past. The possibility, or rather the necessity, of mistaking Socrates puts the question of likeness at the center of the problem of being and truth. The being and nonbeing of the images involves as well the issue of Plato's representation of Socrates. Titled in the New School course catalog as, Plato's Sophist (core).
