Søren Kierkegaard is one of the key figures of nineteenth century thought, whose influence on subsequent philosophy, theology and literature is both extensive and profound. Fear and Trembling, which investigates the nature of faith through an exploration of the story of Abraham and Isaac, is one of Kierkegaard’s most compelling and widely read works. It combines an arresting narrative, an unorthodox literary structure and a fascinating account of faith and its relation to ‘the ethical’.
