In one sense the whole process of development consists of the formation of habits; for knowledge itself, and the powers of thought, as well as the higher elements in the will, all depend upon the establishment of fixed ways of reacting to given stimuli. Consequently, the general laws of habituation underlie the whole of education. But the term habit is more commonly restricted to those established reactions that act with little or no participation of consciousness, or, in other words, mechanically or automatically. Such habits as these begin to form very early, and constitute a kind of supporting framework for the higher elements of character.
