Yet all habit involves mechanization. Habit is impossible without setting up a mechanism of action, physiologically engrained, which operates "spontaneously," automatically, whenever the cue is given. But mechanization is not of necessity _all_ there is to habit. Consider the conditions under which the first serviceable abilities of life are formed. When a child begins to walk he acutely observes, he intently and intensely experiments. He looks to see what is going to happen and he keeps curious watch on every incident. What others do, the assistance they give, the models they set, operate not as limitations but as encouragements to his own acts, reinforcements of personal perception and endeavor. The first toddling is a romantic adventuring into the unknown; and every gained power is a delightful discovery of one's own powers and of the wonders of the world. We may not be able to retain in adult habits this zest of intelligence and this freshness of satisfaction in newly discovered powers. But there is surely a middle term between a normal exercise of power which includes some excursion into the unknown, and a mechanical activity hedged within a drab world. Even in dealing with inanimate machines we rank that invention higher which adapts its movements to varying conditions. All life operates through a mechanism, and the higher the form of life the more complex, sure and flexible the mechanism. This fact alone should save us from opposing life and mechanism, thereby reducing the latter to unintelligent automatism and the former to an aimless splurge. How delicate, prompt, sure and varied are the movements of a violin player or an engraver! How unerringly they phrase every shade of emotion and every turn of idea! Mechanism is indispensable. If each act has to be consciously searched for at the moment and intentionally performed, execution is painful and the product is clumsy and halting. Nevertheless the difference between the artist and the mere technician is unmistakeable. The artist is a masterful technician. The technique or mechanism is fused with thought and feeling. The "mechanical" performer permits the mechanism to dictate the performance. It is absurd to say that the latter exhibits habit and the former not. We are confronted with two kinds of habit, intelligent and routine. All life has its élan, but only the prevalence of dead habits deflects life into mere élan.
