In his scientific genius, man has wrought material miracles and has transformed his world. He has harnassed nature and has developed great civilizations.

He has demonstrated little spiritual genius and has made little progress toward the realization of human brotherhood. In the contemporary atomic age, this could prove man's fatal weakness.
