Abstract
DOES ARISTOTLE’S PHILOSOPHY rule out evolution? The short answer is “Yes, but...!”; the long answer: “No,... however!” Summarizing his excellent account of the reasoning which led Aristotle in book 7 of the Metaphysics to identify substance in the first place with specific form, W. K. C. Guthrie, in the final volume of his monumental history of Greek philosophy, concluded: “Doubtless this is not a satisfactory explanation of reality. For one thing it makes Darwinian evolution impossible.” The matter, needless to say, is not quite so simple. Two questions are immediately raised: Does the doctrine of substantial form necessarily exclude evolution? If so, is this of itself sufficient reason for us to reject form? With these questions in mind, I propose.
