The World as Will and Representation (Die Welt als Wille und Vorstellung) is the central work of the German philosopher Arthur Schopenhauer. The first edition was published in 1818/19, the second expanded edition in 1844, and the third expanded edition in 1859. In 1948, an abridged version was edited by Thomas Mann. The development of Schopenhauer's ideas took place very early in his career (1814–1818) and culminated in the publication of the first volume of Will and Representation in 1819. This first volume consisted of four books – covering his epistemology, ontology, aesthetics and ethics, in order. Much later in his life, in 1844, Schopenhauer published a second edition in two volumes, the first a virtual reprint of the original, and the second a new work consisting of clarifications to and additional reflections on the first. His views had not changed substantially. His belated fame after 1851 stimulated renewed interest in his seminal work, and led to a third and final edition with 136 more pages in 1859, one year before his death. In the preface to the latter, Schopenhauer noted: "If I also have at last arrived, and have the satisfaction at the end of my life of seeing the beginning of my influence, it is with the hope that, according to an old rule, it will last longer in proportion to the lateness of its beginning."
