Grounded in evolutionary and behavioral biology, this highly original and compelling book takes the reader on a journey through the neural circuitry of crying, innate knowledge, reinforcement learning, emotional bonding, embodiment, interpersonal perception, and the ineffable feeling of certainty that characterizes faith. Wathey argues that the feeling of God's presence is spawned by innate neural circuitry, similar to the mechanism that compels an infant to cry out for its mother. In an adult, this circuitry can be activated under conditions that mimic the extreme desperation and helplessness of infancy, generating the compelling illusion of the presence of a loving, powerful, and all-knowing savior. When seen from this perspective, the illusion also appears remarkably like one that has long been familiar to neurologists: the phantom limb of the amputee, spawned by the expectation of the patient's brain that the missing limb should still be there. Including a primer on the basic concepts and terminology of neuroscience, The Phantom God details the neural mechanisms behind the illusions and emotions of spiritual experience.
