through automatism. At the root of the comic there is a sort of rigidity which compels its victims to keep strictly to one path, to follow it straight along, to shut their ears and refuse to listen. In Molière's plays how many comic scenes can be reduced to this simple type: a character following up his one idea, and continually recurring to it in spite of incessant interruptions! The transition seems to take place imperceptibly from the man who will listen to nothing to the one who will see nothing, and from this latter to the one who sees only what he wants to see. A stubborn spirit ends by adjusting things to its own way of thinking, instead of accommodating its thoughts to the things. So every comic character is on the highroad to the above-mentioned illusion, and Don Quixote furnishes us with the general type of comic absurdity.
Is there a name for this inversion of common sense? Doubtless it may be found, in either an acute or a chronic form, in certain types of insanity. In many of its aspects it resembles a fixed idea. But neither insanity in general, nor fixed ideas in particular, are provocative of laughter: they are diseases, and arouse our pity.
