everything in its way and spreading havoc in all directions; he laughs louder than ever when the ball returns to its starting-point after twists and turns and waverings of every kind. In other words, the mechanism just described is laughable even when rectilinear, it is much more so on becoming circular and when every effort the player makes, by a fatal interaction of cause and effect, merely results in bringing it back to the same spot. Now, a considerable number of light comedies revolve round this idea. An Italian straw hat has been eaten up by a horse.2 There is only one other hat like it in the whole of Paris; it MUST be secured regardless of cost. This hat, which always slips away at the moment its capture seems inevitable, keeps the principal character on the run, and through him all the others who hang, so to say, on to his coat tails, like a magnet which, by a successive series of attractions, draws along in its train the grains of iron filings that hang on to each other. And when at last, after all sorts of difficulties, the goal seems in sight, it is found that the hat so ardently sought is precisely the one that has been eaten. The same voyage of discovery is depicted in another equally well-known comedy of Labiche.3 The curtain rises on an old bachelor and an old maid, acquaintances of long standing, at the moment of enjoying their daily rubber. Each of them, unknown to the other, has applied to the same matrimonial agency. Through innumerable difficulties, one mishap following on the heels of another, they hurry along, side by side, right through the play, to the interview which brings them back, purely and simply, into each other's presence. We have the same circular effect, the same return to the starting-point, in a more recent play.4 A henpecked husband imagines he has escaped by divorce from the clutches of his wife and his mother-in-law. He marries again, when, lo and behold, the double combination of marriage and divorce brings back to him his former wife in the aggravated form of a second mother-in-law!
When we think how intense and how common is this type of the comic, we understand why it has fascinated the imagination of certain philosophers. To cover a good deal of ground only to come back unwittingly to the starting-point, is to make a great effort for a result that is nil. So we might be tempted to define the comic in this latter fashion. And such, indeed, seems to be the idea of Herbert Spencer: according to him, laughter is the indication of an effort which suddenly encounters a void. Kant had already said something of the kind: "Laughter is the result of an expectation, which, of a sudden, ends in nothing." No doubt these definitions would apply to the last few examples given, although, even then, the formula needs the addition of sundry limitations, for we often make an ineffectual effort which is in no way provocative of laughter. While, however, the last few examples are illustrations of a great cause resulting in a small effect, we quoted others, immediately before, which might be defined inversely as a great effect springing from a small cause. The truth is, this second definition has scarcely more validity than the first. Lack of proportion between cause and effect, whether appearing in one or in the other, is never the direct source of laughter. What we do laugh at is something that this lack of proportion may in certain cases disclose, namely, a particular mechanical arrangement which it reveals to us, as through a glass, at the back of the series of effects and causes. Disregard this arrangement, and you let go the only clue capable of guiding you through the labyrinth of the comic. Any hypothesis you otherwise would select, while possibly applicable to a few carefully chosen cases, is liable at any moment to be met and overthrown by the first unsuitable instance that comes along.
But why is it we laugh at this mechanical arrangement? It is doubtless strange that the history of a person or of a group should sometimes appear like a game worked by strings, or gearings, or springs; but from what source does the special character of this strangeness arise? What is it that makes it laughable? To this question, which we have already propounded in various forms, our answer must always be the same. The rigid mechanism which we occasionally detect, as a foreign body, in the living continuity of human affairs is of peculiar interest to us as being a kind of ABSENTMINDEDNESS on the part of life. Were events unceasingly mindful of their own course, there would be no coincidences, no conjunctures and no circular series; everything would evolve and progress continuously. And were all men always attentive to life, were we constantly keeping in touch with others as well as with ourselves, nothing within us would ever appear as due to the working of strings or springs. The comic is that side of a person which reveals his likeness to a thing, that aspect of human events which, through its peculiar inelasticity, conveys the impression of pure mechanism, of automatism, of movement without life. Consequently it expresses an individual or collective imperfection which calls for an immediate corrective. This corrective is laughter, a social gesture that singles out and represses a special kind of absentmindedness in men and in events.
But this in turn tempts us to make further investigations. So far, we have spent our time in rediscovering, in the diversions of the grownup man, those mechanical combinations which amused him as a child. Our methods, in fact, have been entirely empirical. Let us now attempt to frame a full and methodical theory, by seeking, as it were, at the fountainhead, the changeless and simple archetypes of the manifold and transient practices of the comic stage. Comedy, we said, combines events so as to introduce mechanism into the outer forms of life. Let us now ascertain in what essential characteristics life, when viewed from without, seems to contrast with mere mechanism. We shall only have, then, to turn to the opposite characteristics, in order to discover the abstract formula, this time a general and complete one, for every real and possible method of comedy.
Life presents itself to us as evolution in time and complexity in space. Regarded in time, it is the continuous evolution of a being ever growing older; it never goes backwards and never repeats anything. Considered in space, it exhibits certain coexisting elements so closely interdependent, so exclusively made for one another, that not one of them could, at the same time, belong to two different organisms: each living being is a closed system of phenomena, incapable of interfering with other systems. A continual change of aspect, the irreversibility of the order of phenomena, the perfect individuality of a perfectly self-contained series: such, then, are the outward characteristics — whether real or apparent is of little moment — which distinguish the living from the merely mechanical. Let us take the counterpart of each of these: we shall obtain three processes which might be called REPETITION, INVERSION, and RECIPROCAL INTERFERENCE OF SERIES. Now, it is easy to see that these are also the methods of light comedy, and that no others are possible.
As a matter of fact, we could discover them, as ingredients of varying importance, in the composition of all the scenes we have just been considering, and, a fortiori, in the children's games, the mechanism of which they reproduce. The requisite analysis would, however, delay us too long, and it is more profitable to study them in their purity by taking fresh examples. Nothing could be easier, for it is in their pure state that they are found both in classic comedy and in contemporary plays.
1. REPETITION.-Our present problem no longer deals, like the preceding one, with a word or a sentence repeated by an individual, but rather with a situation, that is, a combination of circumstances, which recurs several times in its original form and thus contrasts with the changing stream of life. Everyday experience supplies us with this type of the comic, though only in a rudimentary state. Thus, you meet a friend in the street whom you have not seen for an age; there is nothing comic in the situation. If, however, you meet, him again the same day, and then a third and a fourth time, you may laugh at the "coincidence." Now, picture to yourself a series of imaginary events which affords a tolerably fair illusion of life, and within this ever-moving series imagine one and the same scene reproduced either by the same characters or by different ones: again you will have a coincidence, though a far more extraordinary one.
Such are the repetitions produced on the stage. They are the more laughable in proportion as the scene repeated is more complex and more naturally introduced — two conditions which seem mutually exclusive, and which the play-writer must be clever enough to reconcile.
Contemporary light comedy employs this method in every shape and form. One of the best-known examples consists in bringing a group of characters, act after act, into
