I am a theoretical psychologist based in Cambridge. Over fifty years I have been studying the evolution of intelligence and consciousness. I was the first to demonstrate the existence of "blindsight" after brain damage in monkeys, I did research on mountain gorillas with Dian Fossey in Rwanda, I originated the theory of the "social function of intellect, and I have investigated the evolutionary background of religion, art, healing, death-awareness and suicide. I have been honoured with the Martin Luther King Memorial Prize, the Pufendorf Medal and the International Mind and Brain Prize. My most recent books are Seeing Red, and Soul Dust.
