We often fancy that institutions, social custom, collective habit, have been formed by the consolidation of individual habits. In the main this supposition is false to fact. To a considerable extent customs, or wide-spread uniformities of habit, exist because individuals face the same situation and react in like fashion. But to a larger extent customs persist because individuals form their personal habits under conditions set by prior customs. An individual usually acquires the morality as he inherits the speech of his social group. The activities of the group are already there, and some assimilation of his own acts to their pattern is a prerequisite of a share therein, and hence of having any part in what is going on. Each person is born an infant, and every infant is subject from the first breath he draws and the first cry he utters to the attentions and demands of others. These others are not just persons in general with minds in general. They are beings with habits, and beings who upon the whole esteem the habits they have, if for no other reason than that, having them, their imagination is thereby limited. The nature of habit is to be assertive, insistent, self-perpetuating. There is no miracle in the fact that if a child learns any language he learns the language that those about him speak and teach, especially since his ability to speak that language is a pre-condition of his entering into effective connection with them, making wants known and getting them satisfied. Fond parents and relatives frequently pick up a few of the child's spontaneous modes of speech and for a time at least they are portions of the speech of the group. But the ratio which such words bear to the total vocabulary in use gives a fair measure of the part played by purely individual habit in forming custom in comparison with the part played by custom in forming individual habits. Few persons have either the energy or the wealth to build private roads to travel upon. They find it convenient, "natural," to use the roads that are already there; while unless their private roads connect at some point with the high-way they cannot build them even if they would.
