Through a reading of Nietzsche's texts, primarily of Thus Spoke Zarathustra, this article develops a phenomenological description of the variety of intoxication exemplified in conditions of drunkenness, or in states of emotional excess. It treats Thus Spoke Zarathustra as a literary expression of such intoxication, arguing against attempts to find a coherent narrative structure and clear authorial voice behind this text's apparent disorder. Having isolated the intoxicated characteristics of Thus Spoke Zarathustra - its hyperbolic rhetoric and emotions, its lack of (...) balance, its injustice, its shifting and conflicting moods, and its self-contradictions - I then offer an interpretation of the work, and by extension of intoxication itself, in terms of Nietzsche's model of the self as a dynamic multiplicity of forces. At the same time, I argue for a multiple and dynamic conception of personality in general. (shrink)
