Aristotle's Poetics aims to give an account of what he calls 'poetry' (covering the lyric, the epos, and the drama). Aristotle attempts to explain 'poetry' through 'first principles' and by discerning its different genres and component elements. His analysis of tragedy constitutes the core of his discussion. Aristotle's Poetics is universally acknowledged in Western critical tradition.
