This is a talk given as part of the Ecology, Cosmos & Consciousness series at the October Gallery, London, on 27th October 2009. It coincided with the launch of the book of the same title, which explores the history of the concept of the "Noble Savage", and its role in recent debates about primitive war, conservation among indigenous peoples, and the ways in which "evolutionary" models influence our sense of progress.
