were embryonic scientific specialists, it is questionable whether this is the most effective procedure. Considering that the great majority are concerned with the study of sciences only for its effect upon their mental habits--in making them more alert, more open-minded, more inclined to tentative acceptance and to testing of ideas propounded or suggested,--and for achieving a better understanding of their daily environment, it is certainly ill-advised. Too often the pupil comes out with a smattering which is too superficial to be scientific and too technical to be applicable to ordinary affairs. The utilization of ordinary experience to secure an advance into scientific material and method, while keeping the latter connected with familiar human interests, is easier to-day than it ever was before. The usual experience of all persons in civilized communities to-day is intimately associated with industrial processes and results. These in turn are so many cases of science in action. The stationary and traction steam engine, gasoline engine, automobile, telegraph and telephone, the electric motor enter directly into the lives of most individuals. Pupils at an early age are practically acquainted with these things. Not only does the business occupation of their parents depend upon scientific applications, but household pursuits, the maintenance of health, the sights seen upon the streets, embody scientific achievements and stimulate interest in the connected scientific principles. The obvious pedagogical starting point of scientific instruction is not to teach things labeled science, but to utilize the familiar occupations and appliances to direct observation and experiment, until pupils have arrived at a knowledge of some fundamental principles by understanding them in their familiar practical workings. The opinion sometimes advanced that it is a derogation from the "purity" of science to study it in its active incarnation, instead of in theoretical abstraction, rests upon a misunderstanding. AS matter of fact, any subject is cultural in the degree in which it is apprehended in its widest possible range of meanings. Perception of meanings depends upon perception of connections, of context. To see a scientific fact or law in its human as well as in its physical and technical context is to enlarge its significance and give it increased cultural value. Its direct economic application, if by economic is meant something having money worth, is incidental and secondary, but a part of its actual connections. The important thing is that the fact be grasped in its social connections--its function in life.
