In this essay on man, Mr. Fuller expresses what may well be his penultimate view of the human condition. Here, in a mood at once philosophical and involved, Mr. Fuller traces man’s intellectual evolution and weighs his capability for survival on this magnificent craft, this Spaceship Earth, this superbly designed sphere almost negligible in dimension compared to the great vastness of space. Mr. Fuller is optimistic that man will survive and, through research and development and increased industrialization, generate wealth so rapidly that he can do very great things. But, he notes, there must be an enormous educational task successfully accomplished right now to convert man’s tendency toward oblivion into a realization of his potential, to a universe-exploring advantage from this Spaceship Earth.
