Abstract

During the Middle Ages and Rennaissance, it was commonly believed that Aristotle's biological studies reflected his theory of demonstrative science quite well. By contrast, most commentators in the twentieth century have taken it that this is not the case. This is largely the result of preconceptions about what a natural science modelled after the proposals of Aristotle's Posterior Analytics would look like. I argue that these modern preconceptions are incorrect, and that, while the Analytics leaves a variety of issues unanswered that a practicing biology must have answers to (hence Parts of Animals I), Aristotle's biological practice conforms to the Analytics model. It is further argued that establishing this claim requires reading philosophically through entire biological treatises--that is, one will miss the logical structure by following the usual practice of 'sampling' these treatises rather than reading them systematically.
