Arthur Schopenhauer (; German: [ˈaɐ̯tʊɐ̯ ˈʃoːpm̩ˌhaʊ̯ɐ]; 22 February 1788 – 21 September 1860) was a German philosopher. He is best known for his 1818 work The World as Will and Representation (expanded in 1844), wherein he characterizes the phenomenal world as the product of a blind and insatiable metaphysical will. Proceeding from the transcendental idealism of Immanuel Kant, Schopenhauer developed an atheistic metaphysical and ethical system that has been described as an exemplary manifestation of philosophical pessimism, rejecting the contemporaneous post-Kantian philosophies of German idealism. Schopenhauer was among the first thinkers in Western philosophy to share and affirm significant tenets of Eastern philosophy (e.g., asceticism, the world-as-appearance), having initially arrived at similar conclusions as the result of his own philosophical work.

The world is full of hundreds of beautiful things we can never possibly have time to discover, and there is no time to be unkind or envious or ungenerous, and no sense in enslaving the mind to the trivialities of the moment. For you can be equal to the greatness of life only by marching with it; not by seeking love but by giving it, nor seeking to be understood but learning to understand. And when it is all over, there will be an agony of remorse because one spared the effort and did not make more of that little span of opportunity; and knowing reality at last, who knows but that one will look back with unassuageable regret upon one's pitiful little faith.
