Ipotesi sulla catarsi nella Poetica e nella Politica di Aristotele

In Aristotle's Politics viii 7, 1341b 38-40, there is a reference to some books peri poietikes in which katharsis will be explained more clearly. The future tense of the verb is important and may be the sign of the aristotelian origin of the reference; it would prove in an indisputable way that, when writing Pol. vii-viii , Aristotle thought of a Poetics as the obvious sequel for the discussion about educational problems. So, the logical connection of the argument in Politics and Poetics is in agreement with (and is confirmed by) the famous definition of tragedy in Poet. 6, 1449b 24-28: here Aristotle says that the various items of the definition must be obtained from "the things already said", but the reference is not fully satisfied by Poetics 1-5: in these chapters no mention is made of katharsis, pity and fear. For these items the reference is satisfied only by the text of Politics viii 7, and the two references, Pol. viii 7 to a Poetics, Poet.6 (by implication) to Pol. viii 7, agree about the sequel of the books and strengthen each other. But the topics of katharsis and education never are fully clarified, neither in the Politics, nor in the Poetics.
