when they have not been frankly antagonistic. But in Biology of Freedom Francois Ansermet and Pierre Magistretti are at last breaking new ground. This fully illustrated account, rigorous yet lucid and entirely accessible, shows how the plasticity of the brain's neural network allows for successive inscriptions, transcriptions, and retranscriptions of experience, leading to the constitution of an inner reality, an unconscious psychic life unique to each individual. In what amounts to a paradigm shift based on the concept of plasticity, this elegant, seamless collaboration of a psychoanalyst and a neuroscientist bridges the gap between disciplines formerly believed to be incompatible. Ansermet and Magistretti have opened up new areas of exploration of the mind/body connection and profoundly new ways in which to understand the bodily underpinnings of personal freedom, identity, and change.
