Moral conduct differs from immoral conduct in the same manner and in a like degree. The conscientious man is exact in all his transactions. He supplies a precise weight for a specified sum; he gives a definite quality in fulfillment of understanding; he pays the full amount he bargained to do. In times as well as in quantities, his acts answer completely to anticipations. If he has made a business contract he is to the day; if an appointment he is to the minute. Similarly in respect of truth: his statements correspond accurately with the facts. It is thus too in his family life. He maintains marital relations that are definite in contrast with the relations that result from breach of the marriage contract; and as a father, fitting his behavior with care to the nature of each child and to the occasion; he avoids the too much and the too little of praise or blame, reward or penalty. Nor is it otherwise in his miscellaneous acts. To say that he deals equitably with those he employs, whether they behave well or ill, is to say that he adjusts his acts to their deserts; and to say that he is judicious in his charities, is to say that he portions out his aid with discrimination instead of distributing it indiscriminately to good and bad, as do those who have no adequate sense of their social responsibilities. That progress toward rectitude of conduct is progress toward duly-proportioned conduct, and that duly-proportioned conduct is relatively definite, we may see from another point of view. One of the traits of conduct we call immoral, is excess; while moderation habitually characterizes moral conduct. Now excesses imply extreme divergences of actions from some medium, while maintenance of the medium is implied by moderation; whence it follows that actions of the last kind can be defined more nearly than those of the first. Clearly conduct which, being unrestrained, runs into great and incalculable oscillations, therein differs from restrained conduct of which, by implication, the oscillations fall within narrower limits. And falling within narrower limits necessitates relative definiteness of movements. § 27. That throughout the ascending forms of life, along with increasing heterogeneity of structure and function, there goes increasing heterogeneity of conduct--increasing diversity in the sets of external motions and combined sets of such motions--needs not be shown in detail. Nor need it be shown that becoming relatively great in the motions constituting the conduct of the uncivilized man, this heterogeneity has become still greater in those which the civilized man goes through. We may pass at once to that further degree of the like contrast which we see on ascending from the conduct of the immoral to that of the moral.
