'A wonderfully original and masterly overview of how we think about our influence on the world and about how we sometimes develop delusional beliefs about ourselves as agents in the world. Osman is a pioneer in this fast-developing field and has written a clear and lucid book.' - David Shanks, Professor of Psychology, University College London, UK 'An extremely interesting book that conveys some very complex concepts and experiments in a very accessible way. The book is engaging and, unusually for a psychological text, difficult to put down.' - Richard J. Tunney, Associate Professor of Psychology, University of Nottingham, UK
