While the need of application of ideas gained in study is acknowledged by all the more successful methods of instruction, the exercises in application are sometimes treated as devices for fixing what has already been learned and for getting greater practical skill in its manipulation. These results are genuine and not to be despised. But practice in applying what has been gained in study ought primarily to have an intellectual quality. As we have already seen, thoughts just as thoughts are incomplete. At best they are tentative; they are suggestions, indications. They are standpoints and methods for dealing with situations of experience. Till they are applied in these situations they lack full point and reality. Only application tests them, and only testing confers full meaning and a sense of their reality. Short of use made of them, they tend to segregate into a peculiar world of their own. It may be seriously questioned whether the philosophies (to which reference has been made in section 2 of chapter X) which isolate mind and set it over against the world did not have their origin in the fact that the reflective or theoretical class of men elaborated a large stock of ideas which social conditions did not allow them to act upon and test. Consequently men were thrown back into their own thoughts as ends in themselves. However this may be, there can be no doubt that a peculiar artificiality attaches to much of what is learned in schools. It can hardly be said that many students consciously think of the subject matter as unreal; but it assuredly does not possess for them the kind of reality which the subject matter of their vital experiences possesses. They learn not to expect that sort of reality of it; they become habituated to treating it as having reality for the purposes of recitations, lessons, and examinations. That it should remain inert for the experiences of daily life is more or less a matter of course. The bad effects are twofold. Ordinary experience does not receive the enrichment which it should; it is not fertilized by school learning. And the attitudes which spring from getting used to and accepting half-understood and ill-digested material weaken vigor and efficiency of thought.
