A reprint of the 1976 Macmillan edition. This fictional outline of a modern Utopia has been a centre of controversy ever since its publication in 1948. Set in the United States, it pictures a society in which human problems are solved by a scientific technology of human conduct. FROM THE PREFACE: It is now widely recognised that great changes must be made in the American way of life. Not only can we not face the rest of the world while consuming and polluting as we do, we cannot for long face ourselves while acknowledging the violence and chaos in which we live. The choice is clear: either we do nothing and allow a miserable and probably catastrophic future to overtake us, or we use our knowledge about human behaviour to create a social environment in which we shall live productive and creative lives and do so without jeopardising the chances that those who follow us will be able to do the same. Something like a Walden Two would not be a bad start.

Burrhus Frederic Skinner (1904û1990), regarded by many as the most important and influential psychologist since Freud, earned his doctorate in psychology at Harvard University in 1931. Following appointments at the University of Minnesota and Indiana University, he returned to Harvard in 1948. He remained there for the rest of his career, retiring in 1974 as Edgar Pierce Professor of Psychology.
