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.
INSTINCT AND HABIT _VERSUS_ REFLECTION. In the two types of behavior already discussed, man is, as it were, "pushed from behind." In the case of instinct he performs an action simply because he _must_ perform it. Willy-nilly he withdraws his hand from fire, eats when hungry, and sleeps when tired. In the case of habits, once they are acquired, he is also largely dominated by circumstances beyond his own control. The bottle is to the confirmed drunkard almost an irresistible command to drink, the alarm clock to one accustomed to it an equally imperative and not-to-be-disregarded order to arise. The story of the old veteran who was carrying home his dinner and who dropped his hands to his side and his dinner to the gutter when a practical joker called "Attention"; the pathetic plight of the superannuated business man who is totally at a loss away from his familiar duties, are often quoted illustrations of how completely habit may determine a man's actions.
But while in a large portion of our daily duties we are thus at the beck and call of the instincts which are our inheritance and the habits which we have acquired, we may also _control_ our actions. Instead of performing actions as immediate and automatic responses to accustomed stimuli, we may determine our actions, single or consecutive, in the light of absent and future results. To act thus is to act reflectively, and to act reflectively is the only escape from random acts prompted by instinct and routine ones prompted by habit.
