Unlike sculpture’s use of marble or painting’s use of color, poetry, according to Hegel, uses inner images as its material. In using words to evoke these inner images, poetry enables us to recognize them as jointly produced human creations: as having a history, cultural nuances, and evolving social significance. Through poetry, that is, humans can pause to consider their own concepts through the words they themselves jointly invent to signify those concepts. Poetry allows us, then, to become aware of our own minds. Hegel traces the development of poetry and then its evolution into prose. Modern poetry, he suggests, must overcome prose through a combination of word choice, meter, and rhyme scheme. It can fail to be art if it is too didactic or too florid. It also ceases to be art if it becomes too philosophical. At that point, poetry reaches its conceptual end.
