For any activity is original when it first occurs. As conditions are continually changing, new and _primitive_ activities are continually occurring. The traditional psychology of instincts obscures recognition of this fact. It sets up a hard-and-fast preordained class under which specific acts are subsumed, so that their own quality and originality are lost from view. This is why the novelist and dramatist are so much more illuminating as well as more interesting commentators on conduct than the schematizing psychologist. The artist makes perceptible individual responses and thus displays a new phase of human nature evoked in new situations. In putting the case visibly and dramatically he reveals vital actualities. The scientific systematizer treats each act as merely another sample of some old principle, or as a mechanical combination of elements drawn from a ready-made inventory. When we recognize the diversity of native activities and the varied ways in which they are modified through interactions with one another in response to different conditions, we are able to understand moral phenomena otherwise baffling. In the career of any impulse activity there are speaking generally three possibilities. It may find a surging, explosive discharge--blind, unintelligent. It may be sublimated--that is, become a factor coordinated intelligently with others in a continuing course of action. Thus a gust of anger may, because of its dynamic incorporation into disposition, be converted into an abiding conviction of social injustice to be remedied, and furnish the dynamic to carry the conviction into execution. Or an excitation of sexual attraction may reappear in art or in tranquil domestic attachments and services. Such an outcome represents the normal or desirable functioning of impulse; in which, to use our previous language, the impulse operates as a pivot, or reorganization of habit. Or again a released impulsive activity may be neither immediately expressed in isolated spasmodic action, nor indirectly employed in an enduring interest. It may be "suppressed."
