"All things are full of jest; nothing that's plain
But may be witty, if thou hast the vein."

But we are not in the vein except sometimes, and under peculiar circumstances, so that, practically, few sayings are humorous.

It is more difficult to assert that there are any jests which would be appreciated by all. The statement that "some phases of life must stir humour in any man of sanity," is probably too wide. There is little of this universality in the ludicrous, but we shall have some reason for thinking that there is a certain constancy in the mental feeling which awakens it. It is also fixed with regard to each individual. If we had sufficient knowledge, we could predict exactly whether a man would be amused at a certain story, and we sometimes say "Tell that to Mr. —— it will amuse him." But if his nature were not so disposed, no exertions on his part or ours could make him enjoy it. The ludicrous is dependent upon feelings or circumstances, but not upon the will. It is peculiarly involuntary as those know who have tried to smother a laugh. The utmost advance we can make towards making ourselves mirthful is by changing our circumstances. It is said that if a man were to look at people dancing with his ears stopped, the figures moving without accompaniment would seem ludicrous to him, but his merriment would not be great because he would know the strangeness he observed was not real but caused by his own intentional act. We may say that for a thing to appear ludicrous to a man which does not seem so at present, he must change the character of his mind.

There is another kind of constancy which should here be noticed. Some humorous sayings survive for long periods, and occasionally are adopted in foreign countries. In some cases they have immortalized a name, in others we know not who originated them, or to whom they first referred. They seem to be the production, as they are the heritage, not of man but of humanity. It is essential to the permanence of humour that it should refer to large classes, and awaken emotions common to many. If Socrates and Xantippe, the philosopher and the shrew, had not represented classes, and an ordinary connection in life, we should have been little amused at their differences.[16]

Having mentioned these few first aspects in which humour is constant, we now come to the wider field of its variation. It may be said to vary with the age, with the century, with classes of society, with the time of life, nay, it has been asserted, with the very hours of the day! The simplest mode in which we can demonstrate this character of humour is to consider some of those things which although amusing to others are not so to us, and those which amuse us, but not others; we sometimes regard as ludicrous what is intended to be humorous, sometimes on the other hand we view as humorous what is seriously meant, and sometimes we take gravely what is intended to be amusing.

A man may make what he thinks to be a jest, and be neither humorous nor ludicrous, and a man may cause others to laugh without being one or the other; for what he says may be amusing, although he does not intend it to be so, or he may be merely relating some actual occurrence. Occasionally, there is some doubt as to whether we regard things as ludicrous or humorous. This is seen in some proverbs.

But the most common and strongly marked instances of variation are where what is seriously taken by one person is regarded as ludicrous by another. Thus the conception of the qualities desirable in public speaking are very different on this side to the Atlantic from what they are on the other, and what appears to us to partake of the ludicrous, seems to them to be only grand, effective, and appropriate. "In patriotic eloquence," says a U.S. journal, "our American stump-speakers beat the world. They don't stand up and prose away so as to put an audience to sleep, after the lazy genteel aristocratic style of British Parliamentary speech-making." This boast is certainly just. There is a vigour about the popular style of American oratory that we are sure has never been equalled in the British Parliament. A paper of the interior in paying a glowing tribute to the eloquence of the Fourth of July orator who officiated in the town where the journal is published, says—"Although he had a platform ten feet square to orate upon, he got so fired up with patriotism that it wasn't half big enough to hold him: his fist collided three times with the President of the day, besides bunging the eye of the reader of the Declaration, and every person on the stage left it limping." Such a style of oratory would leave durable impressions, and be felt as well as heard.

It cannot be doubted that our mental state, whether temporary or habitual, exercises a great influence over us in regard to humour. Temperament must modify all our emotional feelings, some are naturally gay and hilarious, some grave and austere, children laugh from little more than exuberance of spirits, and joyousness causes us to seek pleasure, to notice ludicrous combinations which would otherwise escape us, and renders us sensitive of all humorous impressions. But the cares of life have generally the effect of making men grave even where there is no lack of imagination. Some have been so serious in mood that it has been recorded that they were never known to laugh, as it is said of Philip the Third of Spain that he only did so once—on reading Don Quixote.

How little attempt at humour is there in most of our literary works! True, humour is rather the language of conversation, and we may expect it as little in writing, as we do sentiment in society. But even in its own special province it is lacking, there is generally in our festive gatherings more of what is dull than of what is playful and pleasant. Perhaps our cloudy skies may have some influence—it is impossible to doubt that climate affects the mental disposition of nations. The natives of Tahiti in their soft southern isle are gay and laughter-loving; the Arab of the desert is fierce and warlike, and seldom condescends to smile. Sydney Smith said "it would require a surgical operation to get a joke into the understanding of a Scotchman;" but the Irishman in his mild variable climate is ready to be witty under all circumstances. Flögel, writing in Germany, observes that "humour is not a fruit to be gathered from every bough; you can find a hundred men able to draw tears for every one that can raise a laugh."

There is also a great difference between individuals in this respect. Some are naturally bright and jocund, and others are misanthropic and manufacture out of very trite materials a sort of snap-dragon wit, which flares up in an instant, is as soon out, and generally burns somebody's fingers. It may be urged on the contrary that many celebrated wits as Mathews, Leech, and others, have been melancholy men. But despondency is often found in an excitable temperament which is not unfavourable to humour, for the man who is unduly depressed at one moment is likely to be immoderately elated at another. Old Hobbes was of opinion that laughter arose from pride, upon which Addison remarked that according to that theory, if we heard a man laugh, instead of saying that he was very merry, we should say that he was very proud. We have already observed that some men are disinclined to laugh because they are of an earnest turn of mind, constantly pondering upon their affairs and the possibility of transforming a shilling into a pound. Such are those to whom Carlyle referred when he said that "the man who cannot laugh is only fit for treasons, stratagems and spoils." But there are a few persons who follow Lord Chesterfield in systematically suppressing this kind of demonstration. They think it derogatory, and in them pride is antagonistic to humour. A man who is free and easy and talkative, gains in one direction what he loses in another. We love him as a frank, genial fellow, but can never regard him with any great reverence. Laughter seems to bespeak a simple docile nature, such as those who assume to rule the world are not willing to have the credit of possessing. It belongs more to the fool than to the rogue, to those who follow than to those who lead. Eminent men do not intentionally avoid laughter; they are not inclined to it; and there are some, who, from being generally of a profound and calculating turn of mind are not given to any exhibition of emotion. It has been said that Diogenes never laughed, and the same has been asserted of Swift. And although we may safely conclude that these statements were not literally true, there was probably some foundation for them. No doubt they appreciated humour, but their minds were earnest and ambitious. Moreover, great wits are accustomed to the character of their own humour, and are often merely repeating what they have heard or said frequently.
