The Anatomies of Thought What do squid think about ?
When we watch a squid facing up to a predator, we see it recoil, agitate the tentacles, spray a jet of ink, and then make use of the temporary blindness of the predator in order to escape to a safe hiding place. Are we able to say what it is thinking ? Evidently, we know that this behaviour is not the result of a reflex unleashed by the sight of an enemy. The mollusc is not however conscious of its acts, at least not in the sense that we, as human beings, understand this term. It is true that we are the product of a evolution of species, and that, although this may not be welcome news for everyone, we share a common ancestry with the octopus, or even the fly. Even if the structure of our cortex, and the invention of language allows us to write about octopuses (or flies), and not the other way round, the fact remains that these evolutive roots, in the same way as other animal species, including invertebrates, have something to teach us about the nature of our thoughts.

Biology in the Bedroom
Inspiring himself from La Philosophie dans le boudoir by Sade and the major philosophical works of the 18th century, Alain Prochiantz, who is a neurobiologist, explains by means of a dialogue, the progress of embryology and neurobiology and gives us the elements so that we can understand and measure the stakes of the recent discovery of the genes of development. Alain Prochiantz heads the Laboratory for the Development and Evolution of the Nervous System at the École normale supérieure. He is notably the author of Strategies of the Embryo, and Claude Bernard, the Physiological Revolution.
