Following the narratives explored in Hominescence, Incandescent and The Bough , Michel Serres continues and concludes his 'grand story' of humanity and humanism. This book weaves together and condenses the overriding philosophical narratives of the previous books and reflects upon Serres' own humanist theoretical system. With characteristic breadth and imagination, in telling the story of humanity, Serres also tells us why Orpheus lost his friend Euridyce; why Eve was really tempted in the garden of Eden, the history of Fetishism and how human being learned to think. The book offers a challenge to the reader: a challenge to live in the fullness of one's humanity.
