Are cosmic rays really cosmic, pervading all space; or are they limited to galaxies such as our Milky Way; or do they originate within the solar system? In the August, 1949 issue of Physics Today, Edward Teller favored the latter theory; the author of the present article surveys the situation and comes to a different conclusion.

Caught between an inescapable and growing involvement in social issues of the day and a longstanding tradition of professional isolationism, scientists have come to realize that habits of objective analysis are a blunt tool for attacking problems of social origin. A philosopher of science, the author finds here an analogy between the questings of research and of a society in transition to suggest an ethical conception which has meaning in both. He writes that there is no turning back of the clock; that “science can no longer be free from society; but it can be free along with society.”
