Thus Spoke Zarathustra is Nietzsche's most problematic text. There appears to be no thematic connection between its four Parts and numerous sections. To make it even worse, the book contains a number of thematic contradictions. The standard approach has been a method of selective reading, that is, most critics select a few brilliant passages for edification and ignore the rest. This approach has turned Nietzsche's text into a collection of disjointed fragments. Going against this prevalent approach, T.K. Seung presents the first unified reading of the whole book. He reads it as the record of Zarathustra's epic journey to find spiritual values in the secular world. The alleged thematic contradictions of the text are shown to indicate the turns and twists that are dictated by the hero's epic battle against his formidable opponent. His heroic struggle is eventually resolved by the power of a pantheistic nature-religion. Thus Nietzsche's ostensibly atheistic work turns out to be a highly religious text. The author uncovers this epic plot by reading Nietzsche's text as a baffling series of riddles and puzzles. Hence his reading is not only edifying but also breathtaking. In this unprecedented enterprise, the author takes a complex interdisciplinary approach, engaging the five disciplines of philosophy, psychology, religious studies, literary analysis, and cultural history.
