212 The factor of formulation, of conscious stating, involved in generalization, should also be a constant function, not a single formal act. Definition means essentially the growth of a meaning out of vagueness into definiteness. Such final verbal definition as takes place should be only the culmination of a steady growth in distinctness. In the reaction against ready-made verbal definitions and rules, the pendulum should never swing to the opposite extreme, that of neglecting to summarize the net meaning that emerges from dealing with particular facts. Only as general summaries are made from time to time does the mind reach a conclusion or a resting place; and only as conclusions are reached is there an intellectual deposit available in future understanding.

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.)

The true purpose of exercises that apply rules and principles is, then, not so much to drive or drill them
