Bringing together Jacques Lacan and Friedrich Nietzsche, Tim Themi focuses on their conceptions of ethics and on their accounts of the history of ethical thinking in the Western tradition. Nietzsche blames Plato for setting in motion a degenerative process that turned ethics away from nature, the body, and its senses, and thus eventually against our capacities for reason, science, and a creative, flourishing life. Dismissing Plato's Supreme Good as a "mirage," Lacan is very much in sympathy with Nietzsche's reading. Following this premise, Themi shows how Lacan's ethics might build on Nietzsche's work, thus contributing to our understanding of Nietzsche, and also how Nietzsche's critique can strengthen our understanding of Lacan.
