Schopenhauer's Prize Essay is widely regarded as one of the most brilliant and elegant treatments of free will and determinism. He distinguishes the freedom of acting from the freedom of willing, affirming the former while denying the latter. This volume offers the text in a previously unpublished translation by Eric F.J. Payne, the leading twentieth-century translator of Schopenhauer into English, together with a historical and philosophical introduction by GUnter Zoller.
