ABSTRACT
Naturalism, reductionism, monism Nietzsche’s project during his mature period is to ‘translat[e] man back into nature’ (Nietzsche 1886: 230). As one part of this project, he eliminates entire categories of metaphysical entities, such as substances, souls and egos. As another part, he replaces philosophical explanations of phenomena with psychological or physiological explanations of those phenomena.
