Abstract
The appearance of nuclear weapons suddenly made the extinction of humanity a distinct possibility. In view of this obverse side of scientific progress, attitudes toward science in the general population became ambivalent, at times bordering on hostility. It is argued that to a great extent the scientists themselves are responsible for the tarnished image of science. Accordingly they should restore science to its role of furthering human welfare and, above all, as a source of enlightenment. In our age enlightenment entails emancipating humanity from superstitions generated by the cooptation of science in the service of power.
