The Philosopher's Secret Fire: A History of the Imagination;

The visionary tradition of spirits, gods, and demons continues to subvert our rational universe, erupting from the shadows in times of intense religious and philosophical transition. In this dazzling history, Patrick Harpur links together fields as far apart as Greek philosophy and depth psychology, Renaissance magic and tribal ritual, Romantic poetry and the ecstasy of the shaman, to trace how societies have used myths to make sense of the world.
