"The Poetic Principle" is an essay by Edgar Allan Poe, written near the end of his life and published posthumously in 1850, the year after his death. It is a work of literary criticism, in which Poe presents his literary theory. It is based on a series of lectures Poe had given late in his lifetime.
The essay argues that a poem should be written "for a poem's sake" and that the ultimate goal of art is aesthetic. He also argues against the concept of a long poem, saying that an epic, if it is to be worth anything, must instead be structured as a collection of shorter pieces, each of which is not too long to be read in a single sitting.
