Civilization is based upon the renunciation of impulse gratification and in turn demands the same renunciation of impulses from every newcomer. During the individual's life a constant change takes place from outer to inner compulsion. The influences of civilization work through the erotic components to bring about the transformation of more and more of the selfish tendencies into altruistic and social tendencies. We may indeed assume that the inner compulsion which makes itself felt in the development of man was originally, that is, in the history of mankind, a purely external compulsion. Today people bring along a certain tendency (disposition) to transform the egotistic into social impulses as a part of their hereditary organization, which then responds to further slight incentives to complete the transformation. A part of this transformation of impulse must also be made during life. In this way the individual man is not only under the influence of his own contemporary cultural _milieu_ but is also subject to the influences of his ancestral civilization. If we call a person's individual capacity for transforming his egotistical impulses under the influence of love his cultural adaptability, we can say that this consists of two parts, one congenital and the other acquired, and we may add that the relation of these two to each other and to the untransformed part of the emotional life is a very variable one. In general we are inclined to rate the congenital part too highly, and are also in danger of over-valuing the whole cultural adaptability in its relation to that part of the impulse life which has remained primitive, that is, we are misled into judging people to be "better" than they really are. For there is another factor which clouds our judgment and falsifies the result in favor of what we are judging. We are of course in no position to observe the impulses of another person. We deduce them from his actions and his conduct, which we trace back to motives springing from his emotional life. In a number of cases such a conclusion is necessarily incorrect. The same actions which are "good" in the civilized sense may sometimes originate in "noble" motives and sometimes not. Students of the theory of ethics call only those acts "good" which are the expression of good impulses and refuse to acknowledge others as such. But society is on the whole guided by practical aims and does not bother about this distinction; it is satisfied if a man adapts his conduct and his actions to the precepts of civilization and asks little about his motives.
