Arthur Schopenhauer (22 February 1788 – 21 September 1860) was a German philosopher best known for his book, The World as Will and Representation (German: Die Welt als Wille und Vorstellung), in which he claimed that our world is driven by a continually dissatisfied will, continually seeking satisfaction. Influenced by Eastern philosophy, he maintained that the "truth was recognized by the sages of India"; consequently, his solutions to suffering were similar to those of Vedantic and Buddhist thinkers (i.e., asceticism). His faith in "transcendental ideality" led him to accept atheism.
At age 25, he published his doctoral dissertation, On the Fourfold Root of the Principle of Sufficient Reason, which examined the four distinct aspects of experience in the phenomenal world; consequently, he has been influential in the history of phenomenology. He has influenced many thinkers, including Friedrich Nietzsche, Richard Wagner, Otto Weininger, Ludwig Wittgenstein, Erwin Schrödinger, Albert Einstein, Sigmund Freud, Otto Rank, Carl Jung, Joseph Campbell, Leo Tolstoy, Thomas Mann, Jorge Luis Borges, Mustafa Mahmud and Edouard d'Araille among others.
