1991 0-7734-9916-4 Explores the logic of not-knowing, dramatically presented in the middle-period dialogues of Plato. Contends that Plato first perceived such a logic of not-knowing in the person and behaviour of the man Socrates. Argues that Plato developed the same logic in the literary character Socrates in his dialogues and presented it to his contemporaries as a model of human excellence, as the new arete designed to supplant precedent and then contemporary contenders to model status. Challenges the traditional interpretation of Plato. Offers a new interpretation of Plato as the elaborator of the hypothetical method, termed "Erotic-hypothesizing", which speaks of human possibility and human limitation.
