Friedrich Wilhelm Nietzsche (Ph.D., Philology, Leipzig University, 1869) was a German philosopher of the late 19th century who challenged the foundations of Christianity and traditional morality. 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. Central to his philosophy is the idea of “life-affirmation,” which involves a questioning of all doctrines that drain life's expansive energies, however socially prevalent those views might be. Often referred to as one of the first existentialist philosophers along with Søren Kierkegaard (1813–1855).

“The worst sickness of men tends to originate in the sentimental way they try to combat their sicknesses. What seems like an easy cure, in the long run produces something worse than what it's supposed to overcome. Fake consolations always have to be paid for with a general and profound worsening of the original complaint.”

“The anthropological criminologists tell us that the typical criminal is ugly: monstrum in fronte, monstrum in animo [monstrous in appearance, monstrous in spirit].”
