“It would be as one-sided to assess the effects of science on society as of society on science.”
Preface
Science in History (1954)
Context: In this science the illustrations and examples are not confined in their effect merely to the practice they afford in the analytical art, but [... ] they also store the mind with independent geometrical and physical knowledge. Besides, it should be considered, that the only effectual method of impressing abstract formulae and rules upon the memory, and, indeed, of making them fully and clearly apprehended by the understanding, is by examples of their practical application.
“There is only one science, physics: everything else is social work.”

Context: … All other languages can be translated into the thing-language, but the thing-language cannot be translated into any other language. Its terms can only be reduced to what are called "ostensive" definitions. These consist merely of pointing or otherwise evoking a direct experience. Hence, the thing-language is absolutely basic. Out of this basic language, we build up the other languages of the sciences, beginning with the language of physics, and proceeding to biology, psychology, and the social sciences.
