On the Parts of Animals

Aristotle is without question the founder of the science of biology. In his treatise On the Parts of Animals, he develops his systematic principles for biological investigation, and explanation, and applies those principles to explain why the different animal kinds have the different parts that they do. It is one of the greatest achievements in the history of science. This new translation from the Greek aims to reflect the subtlety and detail of Aristotle's reasoning. The commentary provides help in understanding each argument as well as an integrated account of the goals and methods of the work taken as a whole.
