”THIS BOOK is based on two assumptions of ours. One, it seems to us, is indisputable; the other, highly questionable. We refer to the beliefs that (a) in general, the survival of our society is threatened by an increasing number of unprecedented and, to date, insoluble problems; and (b) that something can be done to improve the situation. If you do not know which of these is indisputable and which questionable, you have just finished reading this book.”
