Instincts and habits produce impulses. The savage eats as often as he feels like it, if he can find berries or fruit or bring down game; impulse alone governs his conduct. But two other elements enter in to modify impulse, as experience teaches wisdom. The self-indulgent man remembers after a little that indulgence of impulse has resulted sometimes in pain rather than satisfaction, and his imagination pictures a recurrence of the unhappy experience. Feeling becomes a guide to regulate impulse. Feeling in turn compels thought. Presently the individual who is going through the civilizing process formulates a resolve and a theory, a resolve to eat at regular times and to abstain from foods that injure him, a theory that intelligent restraint is better than unregulated indulgence. In a similar way the individual acts with reference to selecting his environment. Instinct and habit act conservatively, impelling the individual to remain in the place where he was born and reared, and to follow the occupation of his father. But he feels the discomforts of the climate or the restrictions of his particular environment, he thinks about it, bringing to bear all the knowledge that he possesses, and he makes his choice between going elsewhere or modifying his present environment. Discovery and invention are both products of such choices as these.

364. Desires and Interests.—These complexes of thinking, feeling, and willing make up the conscious desires and interests that mould the individual life. Through the processes of attention to the stimuli that act upon human nature, discrimination between them, association of impressions and ideas that come from present and past experience, and deliberate judgments of value, the mind moves to action for the satisfaction of personal desires and interests. These desires and interests have been classified in various ways. For our present purpose it is useful to classify them as those that centre in the self, and those that centre in others beyond the self. The primitive desires to get food and drink, to mate, and to engage in muscular activity, all look toward the self-satisfaction which comes from their indulgence. There are various acquired interests that likewise centre in the self. The individual goes to college for the social pleasure that he anticipates, for intellectual satisfaction, or to equip himself with a training that will enable him to win success in the competition of business. In the larger society outside of college the art-lover gathers about him many treasures for his own æsthetic delight, the politician exerts himself for the attainment of power and position, the religious devotee hopes for personal favors from the unseen powers. These are on different planes of value, they are estimated differently by different persons, but they all centre in the individual, and if society benefits it is only indirectly or accidentally.

As the individual rises in the scale of social intelligence, his interests become less self-centred, and as he extends his acquaintance and associations the scope of his interests enlarges. He begins to act with reference to the effect of his actions upon others. He sacrifices his own convenience for his roommate; he restrains his self-indulgence for the sake of the family that he might disgrace; he exerts himself in athletic prowess for the honor of the college to which he belongs; he is willing to risk his life on the battle-field in defense of the nation of which he is a citizen; he consecrates his life to missionary or scientific endeavor in a far land for the sake of humanity's gain. These are the social interests that dominate his activity. Mankind has risen from the brute by the process that leads the individual up from the low level of life moulded by primitive desires to the high plane of a life directed by the broad interests of society at large. It is the task of education to reveal this process, and to provide the stimuli that are needed for its continuance.

365. Personality.—No two persons are actuated alike in daily conduct. The pull of their individual desires is not the same, the influence of the various social interests is not in the same proportion. The situation is complicated by hereditary tendencies, and by physical and social environment. Consequently every human being possesses his own distinctive individuality or personality. Variations of personality can be classified and various persons resemble each other so much that types of personality are distinguished. Thus we distinguish between weak personality and forceful personality, according to the strength of individuation, a narrow or a broad personality according as interests are few and selfish or broadly social, a fixed or a changing personality according to conservatism or unsettled disposition. Personality is a distinction not always appreciated, a distinction that separates man from the brute because of his self-consciousness and power of self-direction by rational processes, and relieves him from the dead level that would exist in society if every individual were made after the same pattern. It is the secret of social as well as individual progress, for it is a great personality that sways the group. It is the great boon of present life and the great promise of continued life hereafter.
