The fallacy in these versions of the same idea is perhaps the most pervasive of all fallacies in philosophy. So common is it that one questions whether it might not be called the philosophical fallacy. It consists in the supposition that whatever is found true under certain conditions may forthwith be asserted universally or without limits and conditions. Because a thirsty man gets satisfaction in drinking water, bliss consists in being drowned. Because the success of any particular struggle is measured by reaching a point of frictionless action, therefore there is such a thing as an all-inclusive end of effortless smooth activity endlessly maintained. It is forgotten that success is success of a specific effort, and satisfaction the fulfilment of a specific demand, so that success and satisfaction become meaningless when severed from the wants and struggles whose consummations they are, or when taken universally. The philosophy of Nirvana comes the closest to admission of this fact, but even it holds Nirvana to be desirable.
Habit is however more than a restriction of thought. Habits become negative limits because they are first positive agencies. The more numerous our habits the wider the field of possible observation and foretelling. The more flexible they are, the more refined is perception in its discrimination and the more delicate the presentation evoked by imagination. The sailor is intellectually at home on the sea, the hunter in the forest, the painter in his studio, the man of science in his laboratory. These commonplaces are universally recognized in the concrete; but their significance is obscured and their truth denied in the current general theory of mind. For they mean nothing more or less than that habits formed in process of exercising biological aptitudes are the sole agents of observation, recollection, foresight and judgment: a mind or consciousness or soul in general which performs these operations is a myth.
The doctrine of a single, simple and indissoluble soul was the cause and the effect of failure to recognize that concrete habits are the means of knowledge and thought. Many who think themselves scientifically emancipated and who freely advertise the soul for a superstition, perpetuate a false notion of what knows, that is, of a separate knower. Nowadays they usually fix upon consciousness in general, as a stream or process or entity; or else, more specifically upon sensations and images as the tools of intellect. Or sometimes they think they have scaled the last heights of realism by adverting grandiosely to a formal knower in general who serves as one term in the knowing relation; by dismissing psychology as irrelevant to knowledge and logic, they think to conceal the psychological monster they have conjured up.
Now it is dogmatically stated that no such conceptions of the seat, agent or vehicle will go psychologically at the present time. Concrete habits do all the perceiving, recognizing, imagining, recalling, judging, conceiving and reasoning that is done. “Consciousness,” whether as a stream or as special sensations and images, expresses functions of habits, phenomena of their formation, operation, their interruption and reorganization.
Yet habit does not, of itself, know, for it does not of itself stop to think, observe or remember. Neither does impulse of itself engage in reflection or contemplation. It just lets go. Habits by themselves are too organized, too insistent and determinate to need to indulge in inquiry or imagination. And impulses are too chaotic, tumultuous and confused to be able to know even if they wanted to. Habit as such is too definitely adapted to an environment to survey or analyze it, and impulse is too indeterminately related to the environment to be capable of reporting anything about it. Habit incorporates, enacts or overrides objects, but it doesn’t know them. Impulse scatters and obliterates them with its restless stir. A certain delicate combination of habit and impulse is requisite for observation, memory and judgment. Knowledge which is not projected against the black unknown lives in the muscles, not in consciousness.
We may, indeed, be said to know how by means of our habits. And a sensible intimation of the practical function of knowledge has led men to identify all acquired practical skill, or even the instinct of animals, with knowledge. We walk and read aloud, we get off and on street cars, we dress and undress, and do a thousand useful acts without thinking of them. We know something, namely, how to do them. Bergson’s philosophy of intuition is hardly more than an elaborately documented commentary on the popular conception that by instinct a bird knows how to build a nest and a spider to weave a web. But after all, this practical work done by habit and instinct in securing prompt and exact adjustment to the environment is not knowledge, except by courtesy. Or, if we choose to call it knowledge—and no one has the right to issue an ukase to the contrary—then other things also called knowledge, knowledge of and about things, knowledge that things are thus and so,
