Recent neuroscience, in replacing the old model of the brain as a single centralized source of control, has emphasized “plasticity,” the quality by which our brains develop and change throughout the course of our lives. Our brains exist as historical products, developing in interaction with themselves and with their surroundings.

Hence there is a thin line between the organization of the nervous system and the political and social organization that both conditions and is conditioned by human experience. Looking carefully at contemporary neuroscience, it is hard not to notice that the new way of talking about the brain mirrors the management discourse of the neo-liberal capitalist world in which we now live, with its talk of decentralization, networks, and flexibility. Consciously or unconsciously, science cannot but echo the world in which it takes place.

In the neo-liberal world, “plasticity” can be equated with “flexibility”—a term that has become a buzzword in economics and management theory. The plastic brain would thus represent just another style of power, which, although less centralized, is still a means of control.

In this book, Catherine Malabou develops a second, more radical meaning for plasticity. Not only does plasticity allow our brains to adapt to existing circumstances, it opens a margin of freedom to intervene, to change those very circumstances. Such an understanding opens up a newly transformative aspect of the neurosciences.

In insisting on this proximity between the neurosciences and the social sciences, Malabou applies to the brain Marx’s well-known phrase about history: people make their own brains, but they do not know it. This book is a summons to such knowledge.

In the usual order of things, lives run their course and eventually one becomes who one is. Bodily and psychic transformations do nothing but reinforce the permanence of identity. But as a result of serious trauma, or sometimes for no reason at all, a subject's history splits and a new, unprecedented persona comes to live with the former person - an unrecognizable persona whose present comes from no past and whose future harbors nothing to come; an existential improvisation, a form born of the accident and by accident. Out of a deep cut opened in a biography, a new being comes into the world for a second time. 

What is this form? A face? A psychological profile? What ontology can it account for, if ontology has always been attached to the essential, forever blind to the aléa of transformations? What history of being can the plastic power of destruction explain? What can it tell us about the explosive tendency of existence that secretly threatens each one of us? 

Continuing her reflections on destructive plasticity, split identities and the psychic consequences experienced by those who have suffered brain injury or have been traumatized by war and other catastrophes, Catherine Malabou invites us to join her in a philosophic and literary adventure in which Spinoza, Deleuze and Freud cross paths with Proust and Duras.
