"The World as Will and Idea (Vol. 3 of 3)" by Arthur Schopenhauer is a philosophical work first published in 1818. Building on Kantian idealism, Schopenhauer argues that the world exists as representation dependent on a perceiving mind, while its inner essence is a blind, unconscious will—the source of all suffering. Through four books, he explores epistemology, ontology, aesthetics, and ethics, proposing that aesthetic experience offers brief escape and only ascetic negation of will brings true redemption.
