Habit is the mainspring of human action, and habits are formed for the most part under the influence of the customs of a group. The organic structure of man entails the formation of habit, for, whether we wish it or not, whether we are aware of it or not, every act effects a modification of attitude and set which directs future behavior. The dependence of habit-forming upon those habits of a group which constitute customs and institutions is a natural consequence of the helplessness of infancy. The social consequences of habit have been stated once for all by James: “Habit is the enormous fly-wheel of society, its most precious conservative influence. It alone is what keeps us within the bounds of ordinance, and saves the children of fortune from the uprisings of the poor. It alone prevents the hardest and most repulsive walks of life from being deserted by those brought up to tread therein. It keeps the fisherman and the deck-hand at sea through the winter; it holds the miner in his darkness, and nails the country-man to his log cabin and his lonely farm through all the months of snow; it protects us from invasion by the natives of the desert and the frozen zone. It dooms us all to fight out the battle of life upon the lines of our nurture or our early choice, and to make the best of a pursuit that disagrees, because there is no other for which we are fitted and it is too late to begin again. It keeps different social strata from mixing.” The influence of habit is decisive because all distinctively human action has to be learned, and the very heart, blood and sinews of learning is creation of habitudes. Habits bind us to orderly and established ways of action because they generate ease, skill and interest in things to which we have grown used and because they instigate fear to walk in different ways, and because they leave us incapacitated for the trial of them. Habit does not preclude the use of thought, but it determines the channels within which it operates. Thinking is secreted in the interstices of habits. The sailor, miner, fisherman and farmer think, but their thoughts fall within the framework of accustomed occupations and relationships. We dream beyond the limits of use and wont, but only rarely does revery become a source of acts which break bounds; so rarely that we name those in whom it happens demonic geniuses and marvel at the spectacle. Thinking itself becomes habitual along certain lines; a specialized occupation. Scientific men, philosophers, literary persons, are not men and women who have so broken the bonds of habits that pure reason and emotion undefiled by use and wont speak through them. They are persons of a specialized infrequent habit. Hence the idea that men are moved by an intelligent and calculated regard for their own good is pure mythology. Even if the principle of self-love actuated behavior, it would still be true that the _objects_ in which men find their love manifested, the
