Raymond Ruyer’s writings are quietly astounding provocations for a more careful understanding of morphogenesis, not only of living beings, but of the almost magical, elusive processes by which such beings form themselves. This book makes us rethink the relations between philosophy, biology, science and technology by insisting on the self-orienting forces that make and direct life.

At long last Ruyer’s essential text is available in English. Thanks to Roffe and de Weydenthal’s graceful and reliable translation, Anglophone readers will now know why Deleuze and many other French thinkers have found Ruyer such an innovative and provocative figure in the philosophy of biology.

It is because Ruyer understands machines very well that he is able to clarify the confusion often arising between machines and life forms. His critique of misplaced vitalism is as perceptive as that of misplaced mechanism. This is why his philosophy of biology is becoming even more relevant today when we have to understand Earth as an entanglement of life forms and machines.
