"For he who does not tremble at the sword,
Who quails not with his head upon the block,
Turn but a jest against him, loses heart.
The shafts of wit slip through the stoutest mail;
There is no man alive that can live down
The unextinguishable laughter of mankind."

Aristotle defines the ludicrous to be "a certain error and turpitude unattended with pain, and not destructive," a statement which may refer to moral or physical defects. Cicero and Quintilian, looking probably at satire, consider it to be mostly directed against the shortcomings and offences of men. Bacon in his "Silva Silvarum" says the objects of laughter are deformity, absurdity, and misfortune, in which we trace a certain severity, although he speaks of "jocular arts" as "deceptions of the senses," such as in masks, and other exhibitions, were much in fashion in his day. Descartes says that we only laugh at those whom we deem worthy of reproach; but Marmontel, the celebrated pupil of Voltaire, takes a view which bespeaks greater cultivation and a progress in society. "A fault in manner," he says, "is laughable; a false pretension is ridiculous, a situation which exposes vice to detestation is comic, a bon mot is pleasant."

Dugald Stewart proceeds so far as almost to exclude vice, for he only specifies "slight imperfections in the character and manners, such as do not excite any moral indignation." He says that it is especially excited by affectation, hypocrisy, and vanity.

We trace in these successive opinions of philosophers an improvement in humour, proportionate to the progress of mankind. As men of literature, they drew general conclusions, and from the higher and more cultivated classes, probably much from books. Had they taken a wider range, their catalogues would have been more comprehensive.

But the amelioration we have traced is as much in the general tone of feeling as in humour itself, if not more. Bitter reflections upon the personal or moral defects of others are not so acceptable now as formerly; the "glorying" over the downfall of our neighbours is less common.

Thus we mark an improvement in the sentiments which accompany the ludicrous, and which many philosophers seem to have mistaken for the ludicrous itself. Neither hostility, indelicacy, nor profanity can create the ludicrous, but where they do not disgust they vivify and make it more effective. It will be observed that in all of them there is something we condemn and disapprove. The joy of gain and advantage was in very early times sufficient to quicken humour in that childlike mirth which flowed chiefly from delight and exultation, but the "laughter of pleasure" has passed away, perhaps we require something more keen or subtle in the maturer age of the world. The accessory emotions are not at present either so joyous or so offensive as they were in bygone times. The "faults in manners" of Marmontel, and the "slight imperfections" of Dugald Stewart, showed that the objectionable stimulants of the ludicrous were assuming a much milder form.

From the views of Archbishop Whately set forth in his "Logic," we might suppose that pleasantries, although not devoid of falsity, were usually of a truly innocuous character—"Jests," he writes, "are mock fallacies, i.e. fallacies so palpable as not to be able to deceive anyone, but yet bearing just the resemblance of argument which is calculated to amuse by contrast." Farther on we read again: "There are several different kind of jokes and raillery, which will be found to correspond with the different kinds of fallacy." On this we may observe that some jests, generally of the "manufactured" class, are founded on a false logical process, but in most cases the error arises more from the matter than from the form, and often from mistakes of the senses. Although nearly every misconception may be represented under the form of false ratiocination, the imperfection almost always lies in one of the premises, and it is seldom that there is plainly a fault of argument in humour. If we claim everything as a fallacy of which there is no evidence, though there seems to be some, we shall embrace a large area—part of which is usually assigned to falsity, and if we consider every mistake to come from wrong deduction, we shall convict mankind of being so full of fallacies as not to be a rational, but a most illogical animal. Whately says, "The pun is evidently in most instances a mock argument founded on a palpable equivocation of the middle term—and others in like manner will be found to correspond to the respective fallacies."

A pun is the nearest approach to a mere mock fallacy of form, and we see what poor amusement it generally affords. To feign that because words have the same sound, they convey the same thoughts or meanings is a fiction as transparent as it is preposterous. A word is nothing but an arbitrary sign, and apart from the thought connected with it, it is an empty unmeaning sound. The link is too slight in puns, the disparity between the things they represent as similar, too great—there is too much falsity. The worst kind of them is where the words are unlike in spelling, and even somewhat so in sound, and where the same reference cannot be made to suit both. Such are puns of the "atrocious" or "villainous" class—a fertile source of bad riddles. For instance, "Why is an old shoe like ancient Greece?" "Because it had a sole on (Solon)." Here the words are very dissimilar and the allusion is imperfect—the description of an old shoe being wrong and forced.

The founders of many of our great families have shown how much this kind of humour was once appreciated by using it in their mottoes. Thus Onslow has "Festina lente" and Vernon more happily "Ver non semper floret." Some puns are amusingly ingenious when the reference hinges well on both words, some additional verbal or other connection is shown, and the words are exactly alike. When there are not two words, but one is used in two senses, there is still greater improvement. Thus the Rev. R. S. Hawker—a man of such mediæval tastes that he was claimed, falsely, I believe, as a Roman Catholic—made an apt reply to a nobleman who had told him in the heat of religious controversy that he would not be priest-ridden—

"Priest-ridden thou! it cannot be
By prophet or by priest,
Balaam is dead, and none but he
Would choose thee for his beast!"
