Friedrich Nietzsche (October 15, 1844–August 25, 1900) was a German philosopher who challenged the foundations of Christianity and traditional morality. His writings on truth, morality, language, aesthetics, cultural theory, history, nihilism, power, consciousness, and the meaning of existence have exerted an enormous influence on Western philosophy and intellectual history.
He was interested in the enhancement of individual and cultural health, and believed in life, creativity, power, and the realities of the world we live in, rather than those situated in a world beyond. His philosophy was one of affirming life, questioning all modes of thought and action that are geared towards wasting life's expansive energies.
Nietzsche's revitalizing philosophy has inspired leading figures in all walks of cultural life, including dancers, poets, novelists, painters, psychologists, philosophers, sociologists and social revolutionaries.
