As a way through the moral predicament of our time, characterized by its ""moral alienation"", the author proposes an ""Ethics of Possibility"". If the old moralities are not working, he asks, might it not be possible to construct a new morality His purpose, therefore, is to show what is permanent in traditional morality, while distinguishing"" those superfluities which were conditionally a given stage of human evolution."" He applies this program to moral issues ranging from sex to atomic warfare. Philosophically, he draws upon Bergson and to some extent on Teilhard de Chardin, and at the same time brings to bear discussion if it has the reading it deserves. It should make an important contribution to the ""moral breakthrough"" which the author believes our day requires.
