In this ambitious and deeply thoughtful work, psychiatrist Christiaan D van der Velde argues that our sense of knowing may be an epiphenomenon of cerebrally produced internal images. Using this concept of cognition as a basis, van der Velde goes on to show its implications for such complex cerebral functions as memory, language, dreaming, body images, the formation of personality, and the encounter of the self with others. He also discusses the challenges of psychopathology and psychotherapy. This cogent, incisive analysis by a leading psychotherapist and researcher in cognition provides much to ponder and many insights into the nature of the brain.
