Besides this, there are a thousand activities and modes of thought that constitute our daily life,—of which we are not conscious at all until we come into contact with other types of life, or until we are prevented from acting according to our custom,—that cannot in any way be claimed to be more reasonable than others, and to which, nevertheless, we cling. These, it would seem, are hardly less numerous in civilized than in primitive culture, because they constitute the whole series of well-established habits according to which the necessary actions of ordinary every-day life are performed, and which are learned less by instruction than by imitation. We may also express these conclusions in another form. While in the logical processes of the mind we find a decided tendency, with the development of civilization, to eliminate traditional elements, no such marked decrease in the force of traditional elements can be found in our activities. These are controlled by custom almost as much among ourselves as they are among primitive man. We have seen why this must be the case. The mental processes which enter into the development of judgments are based largely upon associations with previous judgments. This process of association is the same among primitive men as among civilized men, and the difference consists largely in the modification of the traditional material with which our new perceptions amalgamate. In the case of activities, the conditions are somewhat different. Here tradition manifests itself in an action performed by the individual. The more frequently this action is repeated, the more firmly it will become established, and the less will be the conscious equivalent accompanying the action; so that customary actions which are of very frequent repetition become entirely unconscious. Hand in hand with this decrease of consciousness goes an increase in the emotional value of the omission of such activities, and still more of the performance of actions contrary to custom. A greater will-power is required to inhibit an action which has become well established; and combined with this effort of the will-power are feelings of intense displeasure. Thus an important change from primitive culture to civilization seems to consist in the gradual elimination of what might be called the social associations of sense-impressions and of activities, for which intellectual associations are gradually substituted. This process is accompanied by a loss of conservatism, which, however, does not extend over the field of habitual activities that do not come into consciousness, and only to a slight extent over those generalizations which are the foundation of all knowledge imparted in the course of education. ----- Footnote 8:
