Arthur Schopenhauer (1788 - 1860) was a German philosopher often called the “philosopher of pessimism". He is known for his 1818 work "The World as Will and Representation" (expanded in 1844), Schopenhauer was among the first philosophers in the Western tradition to share and affirm significant tenets of Indian philosophy, such as asceticism, denial of the self, and the notion of the world-as-appearance. His writings influenced later existential philosophy and Freudian psychology.
