experience of various typical interests and occupations with reference to one another. II THOUGHT AND ITS SUBJECT-MATTER: THE ANTECEDENT CONDITIONS AND CUES OF THE THOUGHT-FUNCTION We have discriminated logic in its wider sense, concerned with the sequence of characteristic functions and attitudes in experience, from logic in its stricter meaning, concerned in particular with description and interpretation of the function of reflective thought. We must avoid yielding to the temptation of identifying logic with either of these to the exclusion of the other; or of supposing that it is possible to isolate one finally from the other. The more detailed treatment of the organs and methods of reflection cannot be carried on with security save as we have a correct idea of the historic position of reflection in the evolving of experience. Yet it is impossible to determine this larger placing, save as we have a defined and analytic, as distinct from a merely vague and gross, view of what we mean by reflection--what is its actual constitution. It is necessary to work back and forth between the larger and the narrower fields, transforming every increment upon one side into a method of work upon the other, and thereby testing it. The apparent confusion of existing logical theory, its uncertainty as to its own bounds and limits, its tendency to oscillate from larger questions of the inherent worth of judgment and validity of inference over to details of scientific technique, and to translation of distinctions of formal logic into terms of an investigatory or verificatory process, are indications of the need of this double movement.
