Why should a man marry and have children, study and build a career; why should he invent new techniques, build new institutions, and develop new ideas--when he doubts if there will be a tomorrow which can guarantee the value of human effort? Crucial here for nuclear man is the lack of a sense of continuity, which is so vital for a creative life. He finds himself part of a nonhistory in which only the sharp moment of the here and now is valuable. For nuclear man life easily becomes a bow whose string is broken and from which no arrow can fly. In his dislocated state he becomes paralyzed. His reactions are not anxiety and joy, which were so much a part of existential man, but apathy and boredom.
