"For those with some grounding in the study of human behaviour, Elster does a remarkable job of bringing together seemingly disparate concerns... [T]his essay (as it effectively is) provides a concise overview of his dominant concerns and a useful introduction to his thought."--Ben Saunders, Political Studies Review "I highly recommend the book, which explains in clear and simple terms the complexity of human behavior and the logic that underlies it."--Aaron Ben-Ze'ev, European Legacy
