“The physicist's relativity, which in recent years has changed our whole approach to scientific knowledge, is harder, and therefore easier to understand, than the social scientist's relativity. It is not a slogan, but a fundamental statement about truth to say that no social scientist can completely free himself from the prison of his own culture; he can only interpret what he observes in the scientific framework of his own time. This is true even of the great innovators. They cannot help but translate their revolutionary observations into language and rubrics that have been determined by the progress of science up until their time. Even those discoveries that create new rubrics are relative to the vantage point of their creator.”
