Jaspers, Karl Theodor (1883–1969)

German philosopher, often described as an existentialist. His voluminous writings are filled with highly subjective paraphrases of the great philosophers, followed by appeals to the readers to be concerned with their own existence. He believed that apes are degenerate humans.

Jaspers was born in Oldenburg, studied medicine and psychology, and in 1921 became professor of philosophy at Heidelberg.

His works include General Psychopathology 1913 and Philosophy 1932.
