Abstract
This translation of Thomas' paraphrase and analysis of Aristotle's philosophy of science is, unfortunately, mimeographed and bound in a paper cover. It lacks the introductory material which is needed to orient the reader philosophically and to specify the issues at stake; it also lacks notes giving the meanings of technical terms and comparing the exposition to Aristotle's own text. There is, however, a rather extensive index. The publication of this volume intensifies the historical problem whether commentaries such as this accurately represent medieval conceptions of science. Recent volumes, such as A. C. Crombie's on Grosseteste, indicate that some thinkers at least were arriving at a mathematical conception of physical reality, which could not have been derived from exclusive attention to the Aristotelian corpus.--C.
