Risu inepto res ineptior nulla est.
CATULL., Carm. 39 in Egnat.
Nothing so foolish as the laugh of fools.
Among all kinds of writing, there is none in which authors are more apt to miscarry than in works of humour, as there is none in which they are more ambitious to excel. It is not an imagination that teems with monsters, a head that is filled with extravagant conceptions, which is capable of furnishing the world with diversions of this nature; and yet, if we look into the productions of several writers, who set up for men of humour, what wild, irregular fancies, what unnatural distortions of thought do we meet with? If they speak nonsense, they believe they are talking humour;and when they have drawn together a scheme of absurd, inconsistent ideas, they are not able to read it over to themselves without laughing. These poor gentlemen endeavour to gain themselves the reputation of wits and humorists, by such monstrous conceits as almost qualify them for Bedlam; not considering that humour should always lie under the check of reason, and that it requires the direction of the nicest judgment, by so much the more as it indulges itself in the most boundless freedoms. There is a kind of nature that is to be observed in this sort of compositions, as well as in all other; and a certain regularity of thought which must discover the writer to be a man of sense, at the same time that he appears altogether given up to caprice. For my part, when I read the delirious mirth of an unskilful author, I cannot be so barbarous as to divert myself with it, but am rather apt to pity the man, than to laugh at anything he writes.
The deceased Mr. Shadwell, who had himself a great deal of the talent which I am treating of, represents an empty rake, in one of his plays, as very much surprised to hear one say that breaking of windows was not humour; and I question not but several English readers will be as much startled to hear me affirm, that many of those raving, incoherent pieces, which are often spread among us, under odd chimerical titles, are rather the offsprings of a distempered brain than works of humour.
It is, indeed, much easier to describe what is not humour than what is; and very difficult to define it otherwise than as Cowley has done wit, by negatives. Were I to give my own notions of it, Iwould deliver them after Plato's manner, in a kind of allegory, and, by supposing Humour to be a person, deduce to him all his qualifications, according to the following genealogy. Truth was the founder of the family, and the father of Good Sense. Good Sense was the father of Wit, who married a lady of a collateral line called Mirth, by whom he had issue Humour. Humour therefore being the youngest of this illustrious family, and descended from parents of such different dispositions, is very various and unequal in his temper; sometimes you see him putting on grave looks and a solemn habit, sometimes airy in his behaviour and fantastic in his dress;insomuch that at different times he appears as serious as a judge, and as jocular as a merry-andrew. But, as he has a great deal of the mother in his constitution, whatever mood he is in, he never fails to make his company laugh.
