halts, never repeats itself. It must be changing every moment, for to cease to change would be to cease to live. Then let gesture display a like animation! Let it accept the fundamental law of life, which is the complete negation of repetition! But I find that a certain movement of head or arm, a movement always the same, seems to return at regular intervals. If I notice it and it succeeds in diverting my attention, if I wait for it to occur and it occurs when I expect it, then involuntarily I laugh. Why? Because I now have before me a machine that works automatically. This is no longer life, it is automatism established in life and imitating it. It belongs to the comic.
This is also the reason why gestures, at which we never dreamt of laughing, become laughable when imitated by another individual. The most elaborate explanations have been offered for this extremely simple fact. A little reflection, however, will show that our mental state is ever changing, and that if our gestures faithfully followed these inner movements, if they were as fully alive as we, they would never repeat themselves, and so would keep imitation
