under the pseudonym of 'Johannes de silentio', Kierkegaard expounds his personal view of religion through a discussion of the scene in Genesis in which Abraham prepares to sacrifice his son Isaac at God's command. Believing Abraham's unreserved obedience to be the essential leap of faith needed to make a full commitment to his religion, Kierkegaard himself made great sacrifices in order to dedicate his life entirely to his philosophy and to God. The conviction shown in this religious polemic - that a man can have an exceptional mission in life - informed all Kierkegaard's later writings. His 'teleological suspension of the ethical' challenged the contemporary views of Hegel's universal moral system, and was also hugely influential for both protestant theology and the existentialist movement. Alastair Hannay's introduction evaluates Kierkegaard's philosophy and the ways in which it conflicted with more accepted contemporary views. This edition also includes detailed notes to complement this groundbreaking analysis of religion, and a new chronology. Danish-born Søren Kierkegaard (1813-55) wrote on a wide variety of themes, including religion, psychology, and literature. He is remembered for his philosophy, which pioneered the idea of the Absurd, and was influential in the development of 20th century existentialism. Danish title: 'Frygt og bæven'.
