Nietzsche, Friedrich, Wilhelm.(1844-1900), German philosopher, poet, and classical philologist, who became one of the most provocative and influential thinkers of the 19th century.

His father, a Lutheran minister, died when Nietzsche was five. One of Nietzsche's fundamental contentions was that traditional values (represented primarily by Christianity) had lost their power in the lives of individuals. He expressed this in his proclamation "God is dead." He was convinced that traditional values represented a "slave morality," a morality created by weak and resentful individuals who encouraged such behavior as gentleness and kindness because the behavior served their interests..comprised from Microsoft® Encarta® Encyclopedia 99. © 1993-1998 Microsoft Corporation.
