Arthur Schopenhauer, also known as the “Philosopher of Pessimism”, was a German philosopher and writer. He is known for his 1818 work The World as Will and Representation, which characterizes the phenomenal world as the manifestation of a blind and irrational noumenal will. Building on the transcendental idealism of Immanuel Kant, Schopenhauer developed an atheistic, metaphysical and ethical system that rejected the contemporaneous ideas of German idealism.
