Iain McGilchrist is a psychiatrist, neuroscience researcher, philosopher and literary scholar. In 2009 he rose to worldwide fame with his bestselling book “The Master and His Emissary”, in which he provided scientific evidence that the left and right brain hemispheres represent two fundamentally different ways of experiencing the world. Although My Big TOE posits that all cognitive processes take place within consciousness, not the brain, it draws on the “left brain / right brain” metaphor to illustrate the difference between an intellectual-analytic and an intuitive-holistic way of approaching the world.
