Nietzsche's unpublished notes are extraordinary in both volume and interest, and indispensable to a full understanding of his lifelong engagement with the fundamental questions of philosophy. This volume includes an extensive selection of the notes he kept during the early years of his career. They address the philosophy of Schopenhauer, the nature of tragedy, the relationship of language to music, the importance of Classical Greek culture for modern life, and the value of the unfettered pursuit of truth and knowledge which Nietzsche thought was a central feature of western culture since it was first introduced by Plato. They contain startling and original answers to the questions which were to occupy Nietzsche throughout his life and demonstrate the remarkable stability and consistency of his fundamental concerns. They are presented here in a new translation by Landislaus Lob, and an introduction by Alexander Nehamas sets them in their philosophical and historical contexts.
