Highlights the relevance of Nietzsche's thinking about human nature for contemporary debates in biopolitics and posthumanism Nietzsche coins the enigmatic term homo natura to capture his understanding of the human being as a creature of nature and tasks philosophy with the renaturalisation of humanity. Following Foucault's critique of the human sciences, Vanessa Lemm discusses the reception of Nietzsche's naturalism in philosophical anthropology, psychoanalysis and gender studies. She offers an original reading of homo natura that brings back the ancient Greek idea of nature and sexuality as creative chaos and of the philosophical life as outspoken and embodied truth, perhaps best exemplified by the Cynics' embrace of social and cultural transformation. Vanessa Lemm is Professor of Philosophy, Vice President and Executive Dean at the College of Humanities, Arts and Social Sciences at Flinders University, Australia.
