"…a valuable addition to Aristotle's scholarship on the science of animals."— CHOICE"In this collection of five essays on topics he considers crucial, Pellegrin presents the results of decades of work on Aristotle's understanding of living things and on Aristotle's place in the history of biological and medical thought from antiquity to the present. With the biological works making up a quarter to a third of the corpus, Pellegrin's interpretations of the language, concepts, and arguments in these works turn out to enlighten the whole. The items covered range from final cause and necessity, in living things and in the cosmos at large—where Pellegrin argues that Aristotle rejects both intentional teleology of the Timaeus variety and an exclusive Presocratic mechanism as instruments for explaining cosmic order—to the relation of the abilities and organs of living things to one another, which Pellegrin finds in Aristotle's treatment of animal and plant life. While keeping the Aristotelian text clearly in focus, the author engages at length with other major figures who have contributed to the biological turn. Preus's readable translation of the author's recent Des animaux dans le monde brings an original and challenging statement of Pellegrin's views to the English-speaking public and will be informative for scholars in the histories of philosophy and science alike." — John J.
