Strong Imagination

About this book

Madness is the central mystery of the human psyche. Our minds evolved to give us a faithful understanding of reality, to allow us to integrate into our communities, and to help us adapt our behaviour to our environment. Yet in serious mental illness, the mind does exactly the opposite of these things. The sufferer builds castles of imaginative delusion, fails to adapt, and becomes a stranger among his own people. Yet mental illness is no marginal phenomenon: it is found in all societies and all historical epochs, and the genes that underlie it are quite common. Furthermore, the traits that identify the madman are found in attenuated form in normal thinking and feeling. The persistence of madness, then, is a terrible puzzle from both an evolutionary and a human point of view. In Strong Imagination, Daniel Nettle explores the nature of mental illness, the biological mechanisms that underlie it, and its link to creative genius. He goes on to consider the place of both madness and creative imagination in the evolution of our species. - Jacket flap.
