In the last two books of Politics,Aristotle proposes his ideas concerning the best constitution,among which the system of political education is the core issue.In the educational system of the best constitution,musical-poetic education occupies the most important position,because it is through this education that young members of the city acquire the virtues necessary for happiness.Starting from the intrinsic connection between the best constitution and political education,and based on relevant texts of Politics Books VII–VIII and Poetics,this article offers a complete reconstruction of Aristotle’s theory on musical-poetic education.
