This suggests, by contrast, the opposite mode of stating the problem of logical theory. Generalization of the nature of the reflective process certainly involves elimination of much of the specific material and contents of the thought-situations of daily life and of critical science. Quite compatible with this, however, is the notion that it seizes upon _certain_ specific conditions and factors, and aims to bring them to clear consciousness--not to abolish them. While eliminating the particular material of particular practical and scientific pursuits, (1) it may strive to hit upon the common denominator in the various situations which are antecedent or primary to thought and which evoke it; (2) it may attempt to show how typical features in the specific antecedents of thought call out to diverse typical modes of thought-reaction; (3) it may attempt to state the nature of the specific consequences in which thought fulfils its career. (1) It does not eliminate dependence upon specific occasions as provocative of thought; but endeavors to define _what_ in the various situations constitutes them thought-provoking. The specific occasion is not eliminated, but insisted upon and brought into the foreground. Consequently psychological considerations are not subsidiary incidents, but of essential importance so far as they enable us to trace the generation of the thought-situation. (2) So from this point of view the various types and modes of conceiving, judging, and inference are treated, not as qualifications of thought per se or at large, but of thought engaged in its specific, most economic, effective response to its own particular occasion; they are adaptations for control of stimuli. The distinctions and classifications that have been accumulated in "formal" logic are relevant data; but they demand interpretation from the standpoint of use as organs of adjustment to material antecedents and stimuli. (3) Finally the question of validity, or ultimate objective of thought, is relevant; but is such as a matter of the specific issue of the specific career of a thought-function. All the typical investigatory and verificatory procedures of the various sciences are inherently concerned as indicating the ways in which thought actually brings itself to its own successful fulfilment in dealing with various types of problems.
