In this fascinating and bold discussion, a renowned neurobiologist serves as guide to the most complex physical object in the living world: the human brain. Taking into account the newest brain research--morphological, physiological, chemical, genetic--and placing these findings in the context of psychology, philosophy, art, and literature, Changeux ventures into the unexplored territories where these diverse disciplines intersect.

Changeux's book draws on Plato's notion that the Good, the True, and the Beautiful are celestial essences or ideas, independent but so intertwined as to be inseparable. Placing these essences within the characteristic features of the human brain's neuronal organization, the author addresses unsolved questions in neuroscience today. With imagination and deep insight, Changeux illuminates the evolution of the brain and deciphers what new developments in neuroscience may portend for the future of humanity.
