 The following presentation reviews some of the most central topics we find in the works Aristotle dedicated to (what we call) art. The Poetics is of course our main entry into this, but his published works were actually the only works that were available outside his school throughout antiquity; most probably, non-Aristotelian philosophers from Philodemus to the late neo-Platonists only had access to those works, and not to the Poetics. In modern scholarship, those works are usually marginalized if not dismissed, on the grounds that they do not seem to reflect any deep philosophical insight. And, indeed, they were addressed to a general public. But (as we shall see), nothing indicates that the philosophically less elaborated views of On Poets would have been totally different from those in the Poetics, and in the latter work Aristotle does not hesitate to refer to the former. And the same goes for the Homeric Problems: chapter 25 of the Poetics seems to reformulate in a more abstract way the principles from which Aristotle discussed numerous examples of interpretive problems in that work. It is therefore a plausible hypothesis that Aristotle wanted to provide a broader public an echo of what he was teaching his philosophy students. Aristotle often recommends that we begin with more evident, concrete views before aiming at more sophisticated, deeper insights. Let us follow this methodological recommendation, and begin with the two published works.
