"Fear and Trembling is among the best-known and influential works in nineteenth- and twentieth-century philosophic theology and literature . . . The Book on Adler [is] one of the dark jewels in the history of philosophic psychology. As an examiner of the lives of the mind, of the associative pulses of the imagination, Kierkegaard has only two peers. His inquisition into Adler stands beside those descents into the deeps of the human psyche performed by Dostoevsky and by Nietzsche." -from the Introduction by George Steiner
