We have, therefore, the result (so unfortunate for logic) that logic is not free to go its own way, but is compromised by the assumption that knowledge goes on not in terms of things (I use "things" in the broadest sense, as equaling _res_, and covering affairs, concerns, acts, as well as "things" in the narrower sense), but in terms of a relation _between_ things and a peculiar existence made up of consciousness, or else between things and functional operations of this existence. If it could be shown that psychology is essentially not a science of states of consciousness, but of behavior, conceived as a process of continuous readjustment, then the undoubted facts which go by the name of sensation, perception, image, emotion, concept, would be interpreted to mean peculiar (i.e., specifically qualitative) epochs, phases, and crises in the scheme of behavior. The supposedly scientific basis for the belief that states of consciousness inherently define a separate type of existence would be done away with. Inferential knowledge, knowledge involving reflection, _psychologically_ viewed, would be assimilated to a certain mode of readaptation of functions, involving shock and the need of control; 'knowledge' in the sense of direct non-reflective presence of things would be identified (psychologically) with relatively stable or completed adjustments. I can not profess to speak for psychologists, but it is an obvious characteristic of the contemporary status of psychology that one school (the so-called functional or dynamic) operates with nothing more than a conventional and perfunctory reference to "states of consciousness"; while the orthodox school makes constant concessions to ideas of the behavior type. It introduces the conceptions of fatigue, practice, and habituation. It makes its fundamental classifications on the basis of physiological distinctions (e.g., the centrally initiated and the peripherally initiated), which, from a biological standpoint, are certainly distinctions of structures involved in the performance of acts.
