Crombie's second volume deals with Plato's epistemology, cosmology and theory of forms. The author attempts to fit Plato "more into the company of Aristotle, Hume, Kant or Russell." He distinguishes Plato the poet from Plato the philosopher, and suggests that it is the poetic aspect of Plato's writings which lend credence to the mystical Plato of Plotinus. The analysis is detailed, sometimes tedious, but also at times quite ingenious.--P. S.
