But just as the original nature with which man is born is modifiable, so are his emotional reactions. Each individual's emotional reactions are peculiar and specific, because of the particular contacts to which they have been exposed, and the organization of instincts and habits which have come to be their more or less fixed character. Any emotional experience consists of an intermingling of many and diverse feelings. And these particular complexes of emotions become for each individual organized about particular persons or objects or situations. The emotional reactions of an individual are, indeed, accurately symptomatic of the character of the individual and the culture of his time. They are aroused, it goes without saying, on very different occasions and by very different objects, among different men and different groups. In the sixteenth century pious persons could watch heretics being burned in oil with a sense of deep religious exaltation. Certain Fijian tribes slaughter their aged parents with the most tender filial devotion. In certain savage communities, to eat in public arouses on the part of the individual a sense of acute shame. Since those emotions are, on the whole, pleasantly toned which accompany the fulfillment of instinctive and habitual impulses, and those unpleasantly toned which accompany their frustration, it becomes, as Aristotle pointed out, of the most "serious importance" early to habituate men to the performance of socially useful actions. If good or useful actions are early made habitual, their performance will bring pleasure, and will thereby be better insured than by any amount of preaching or punishment. If the actions which the group approves are not early made habitual in the younger members of the group, they will not be enforced either through logic or electrocution. It is not enough to give people reasons for doing good, they will only do it consistently if the opposite arouses in them more or less abhorrence. People learn to modify their actions on the basis of the pleasure or pain they find in their performance, and the pleasure or pain they will experience depends on the actions to which they are habituated and the emotions which have come to be their characteristic accompaniments.
