All theories of the comic were objected to by the critics on the ground that in defining the comic these theories overlooked the essential element of it. This can be seen from the following theories, with their objections. The comic depends on a contrasting idea; yes, in so far as this contrast effects one comically and in no other way. The feeling of the comic results from the dwindling away of an expectation; yes, if the disappointment does not prove to be painful. There is no doubt that these objections are justified, but they are overestimated if one concludes from them that the essential characteristic mark of the comic has hitherto escaped our conception. What depreciates the general validity of these definitions are conditions which are indispensable for the origin of the comic pleasure, but which will be searched in vain for the nature of comic pleasure. The rejection of the objections and the explanations of the contradictions to the definitions of the comic will become easy for us, only after we trace back comic pleasure to the difference resulting from a comparison of two expenditures. Comic pleasure and the effect by which it is recognized—laughter, can originate only when this difference is no longer utilizable and when it is capable of discharge. We gain no pleasurable effect, or at most a flighty feeling of pleasure in which the comic does not appear, if the difference is put to other use as soon as it is recognized. Just as special precautions must be taken in wit, in order to guard against making new use of expenditure recognized as superfluous, so also can comic pleasure originate only under relations which fulfil this latter condition. The cases in which such differences of expenditure originate in our ideational life are therefore uncommonly numerous, while the cases in which the comic originates from them is comparatively very rare. _The Conditions of Isolation of the Comic_ Two observations obtrude themselves upon the observer who reviews even only superficially the origin of comic pleasure from the difference of expenditure; first, that there are cases in which the comic appears regularly and as if necessarily; and, in contrast to these cases, others in which this appearance depends on the conditions of the case and on the viewpoint of the observer; but secondly, that unusually large differences very often triumph over unfavorable conditions, so that the comic feeling originates in spite of it. In reference to the first point one may set up two classes, the inevitable comic and the accidental comic, although one will have to be prepared from the beginning to find exceptions in the first class to the inevitableness of the comic. It would be tempting to follow the conditions which are essential to each class.
