at bay. We begin, then, to become imitable only when we cease to be ourselves. I mean our gestures can only be imitated in their mechanical uniformity, and therefore exactly in what is alien to our living personality. To imitate any one is to bring out the element of automatism he has allowed to creep into his person. And as this is the very essence of the ludicrous, it is no wonder that imitation gives rise to laughter.
Still, if the imitation of gestures is intrinsically laughable, it will become even more so when it busies itself in deflecting them, though without altering their form, towards some mechanical occupation, such as sawing wood, striking on an anvil, or tugging away at an imaginary bell-rope. Not that vulgarity is the essence of the comic,—although certainly it is to some extent an ingredient,—but rather that the incriminated gesture seems more frankly mechanical when it can be connected with a simple operation, as though it were intentionally mechanical. To suggest this mechanical interpretation ought to be one of the favourite devices of parody. We have reached this result through deduction, but I imagine
