Seen as the original Existentialist, Kierkegaard transformed philosophy with his conviction that we must all create our own nature. Fear and Trembling, his great work of religious anxiety portraying Abraham's sacrifice of his son Isaac, argues that true understanding can only be attained by making a personal 'leap of faith'.
Danish-born S ren Kierkegaard (1813-55) wrote on a wide variety of
themes, including religion, psychology, and literature. He is
remembered for his philosophy, which was influential in the
development of 20th century existentialism.
