"To be aware of the medium in which social intercourse goes on, and of the means and obstacles to its progressive development is to be in command of a knowledge which is thoroughly humanistic in quality. One who is ignorant of the history of science is ignorant of the struggles by which mankind has passed from routine and caprice, from superstitious subjection to nature, from efforts to use it magically, to intellectual self-possession. That science may be taught as a set of formal and technical exercises is only too true. This happens whenever information about the world is made an end in itself. The failure of such instruction to procure culture is not, however, evidence of the antithesis of natural knowledge to humanistic concern, but evidence of a wrong educational attitude.Dislike to employ scientific knowledge as it functions in men's occupations is itself a survival of an aristocratic culture. The notion that "applied" knowledge is somehow less worthy than "pure" knowledge, was natural to a society in which all useful work was performed by slaves and serfs, and in which industry was controlled by the models set by custom rather than by intelligence. Science, or the highest knowing, was then identified with pure theorizing, apart from all application in the uses of life; and knowledge relating to useful arts suffered the stigma attaching to the classes who engaged in them."
