This is the sort of book that many psychologists wish they had written. Wegner's achievement was to collect separate bits of research and put them together in an organized whole, providing impressive support for the notion that the subjective feeling of freely willed actions and thoughts is an illusion. It is an illusion that is constantly with us, and only by examining the research Wegner so brilliantly describes and analyzes, can the illusion be unmasked. Although the book is much admired within psychology currently, over time it will be further recognized as a major achievement. I suspect that these basic ideas will eventually find their way into the public consciousness in some form, where it will have continuing repercussions, including in the literary, visual and performing arts.
