Aristotle's Philosophy of Science

Aristotle is claiming that there simply is any such thing as knowledge or understanding in the proper sense of accidental features. If hiawatha has a broken toe, for instance, this will not interest the aristotelian giraffologist because, in general, giraffes don't have broken toes. Aristotle encourages us to ignore such exceptions and to study only the generalities of nature. Some even say that the posterior analytics is aristotle's treatise on the philosophy of science.
