« Aristote: le philosophe et les savoirs », (Seuil, 2002) a collaborative account of Aristotle’s philosophy by two of France’s most respected scholars of Aristotle, is undoubtedly one of the best in-depth interpretations of Aristotle’s way of thinking to have been published in the last two decades. Crubellier and Pellegrin make no apologies for being passionate admirers of Aristotle, and their passion communicates itself to the reader throughout the book. The guiding thread through their exposition of Aristotle’s thought is the question of knowledge. They see the unity of Aristotle’s thought not so much in the elaboration of a system so much as a way of thinking and, above all, as a way of questioning. As they say, for them, « Aristotle is above all the questioner, the man of problems, discussions and attempts. » This is what makes the development of recent research on Aristotle, perhaps more than in any other area of the history of ancient philosophy, take place in close association with the development of modern philosophy, particularly with respect to analytical and phenomenological philosophy. For anyone with an interest in deepening their understanding of Aristotle as the most important and influential founder of the Western tradition of science and philosophy, Crubellier’s and Pellegrin’s book is essential reading.
