From the preface of Skinners 1948 (reissued 28 years later) masterpiece:
It is now widely recognized that great changes must be made in the Americain 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 used our knowledge about human behavior to create a social environment in which we shall live productive and creative lives and do so without jeopardizing 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.
