III. As the last words indicate, application and generalization lie close together. Mechanical skill for further use may be achieved without any explicit recognition of a principle; nay, in routine and narrow technical matters, conscious formulation may be a hindrance. But without recognition of a principle, without generalization, the power gained cannot be transferred to new and dissimilar matters. The inherent significance of generalization is that it frees a meaning from local restrictions; rather, generalization _is_ meaning so freed; it is meaning emancipated from accidental features so as to be available in new cases. The surest test for detecting a spurious generalization (a statement general in verbal form but not accompanied by discernment of meaning), is the failure of the so-called principle spontaneously to extend itself. The essence of the general is application. (_Ante_, p. 29.) [Sidenote: Fossilized _versus_ flexible principles] The true purpose of exercises that apply rules and principles is, then, not so much to drive or drill them in as to give adequate insight into an idea or principle. To treat application as a separate final step is disastrous. In every judgment some meaning is employed as a basis for estimating and interpreting some fact; by this application the meaning is itself enlarged and tested. When the general meaning is regarded as complete in itself, application is treated as an external, non-intellectual use to which, for practical purposes alone, it is advisable to put the meaning. The principle is one self-contained thing; its use is another and independent thing. When this divorce occurs, principles become fossilized and rigid; they lose their inherent vitality, their self-impelling power. [Sidenote: Self-application a mark of genuine principles] A true conception is a _moving_ idea, and it seeks outlet, or application to the interpretation of particulars and the guidance of action, as naturally as water runs downhill. In fine, just as reflective thought requires particular facts of observation and events of action for its origination, so it also requires particular facts and deeds for its own consummation. "Glittering generalities" are inert because they are spurious. Application is as much an intrinsic part of genuine reflective inquiry as is alert observation or reasoning itself. Truly general principles tend to apply themselves. The teacher needs, indeed, to supply conditions favorable to use and exercise; but something is wrong when artificial tasks have arbitrarily to be invented in order to secure application for principles. CHAPTER SIXTEEN SOME GENERAL CONCLUSIONS We shall conclude our survey of how we think and how we should think by presenting some factors of thinking which should balance each other, but which constantly tend to become so isolated that they work against each other instead of cooperating to make reflective inquiry efficient. § 1. _The Unconscious and the Conscious_
