Kierkegaard is arguably the founder of existentialism, insisting on the irreducibility of human choices against Hegel's deterministic arguments. His most noteworthy work is Either/Or a dialogic text which presents an existential choice between differing aesthetic and ethical world views (not entirely unlike Nietzsche's distinction of apollonian and dionysian), though Kierkegaard was later to view despair as the inevitable conclusion of this existential predicament, with religious faith being the only alternative. Kierkegaard took the view that faith could not be guaranteed through human capacity, using the story of Abraham and Isaac as an example of the absurdist supremacy of religion over even moral considerations.
