Even if we grant that the “gelasts” are getting reduced to the dimensions of a petty sect, the consideration need not deter us from choosing laughter as our theme. Those who have the perfect ear for music are probably but a tiny portion of the human family; yet nobody has suggested {3} that this is an argument against the writing of books on musical form, the science of thorough bass and the rest. The friends of laughter have, however, always existed, and even in these rather dreary days are perhaps more numerous than is often supposed. In support of this idea one may recall the curious fact that, as the essayist just quoted remarks, we all shrink from the “awful imputation” implied in the words “You have no sense of humour”. This recognition of the capacity for appreciating a joke as a human attribute which it is well not to be without is, of course, very far from being proof of a genuine love of fun in the recognisers themselves. Yet it at least attests the existence of this love in a respectable number of their fellows. Now this true friend of laughter (ὁ φιλόγελως) may urge his own objection to our proposed discussion, an objection less irritating perhaps than that of the zealous laughter-hater and of the indifferent agelast, but on the other hand of a more penetrating thrust. He not unnaturally dislikes the idea of his daily pastime being made the subject of grave inquiry. He feels in its acutest form the resentment of the natural man on seeing his enjoyment brought under the scalpel and lens of the scientific inquirer. He urges with force that the chucklings of humour are the very lightest and flimsiest of human things; and that to try to capture them and subject them to serious investigation looks much like the procedure of the child whose impulsive hand would seize and examine his dainty soap bubbles. To these objections from the true friends of the mirthful god one owes it to reply courteously and at length. Yet the answer cannot well be given at the outset. A discourse on laughter can remove this kind of objection, if at all, only by showing in its own treatment of the subject that serious thought may touch even the gossamer wing of the merry {4} sprite and not destroy; that all things, and so the lightest, are things to be comprehended, if only we can reach the right points of view; and that the problems which rise above the mental horizon, as soon as we begin to think about man’s humorous bent, have a quite peculiar interest, an interest in which all who can both laugh at things and ponder on them may be expected to share.
