For I do not think that anybody can give an adequate explanation, though many have attempted to do so, of the cause of laughter, which is excited not merely by words or deeds, but sometimes even by touch. Moreover, there is great variety in the things which raise a laugh, since we laugh not merely at those words or actions which are smart or witty, but also
For, as Cicero [*](De Or. II. lviii. 236. Where? De Or. II. Iviii. 236. ) says,
Laughter has its basis in some kind or other of deformity or ugliness,and whereas, when we point to such a blemish in others, the result is known as wit, it is called folly when the same jest is turned against ourselves. Now, though laughter may be regarded as a trivial matter, and an emotion frequently awakened by buffoons, actors or fools, it has a certain imperious force of its own which it is very hard to resist.
It often breaks out against our will and extorts confession of its power, not merely from our face and voice, but convulses the whole body as well. Again, it frequently turns the scale in matters of great importance, as I have already observed: [*](Where?) for instance, it often dispels hatred or anger.
A proof of this is given by the story of the young men of Tarentum, who had made a number of scurrilous criticisms of Pyrrhus over the dinner table: they were called upon to answer for their statements, and, since the charge was one that admitted neither of denial nor of excuse, they succeeded in escaping, thanks to a happy jest which made the king laugh: for one of the accused said,
Yes, and if the bottle hadn't been empty, we should have killed you!a jest which succeeded in dissipating the animosity which the charge had aroused.
