We may say generally that any fresh acquisition of knowledge destroys one source of amusement and opens another. But if our mental powers were to become perfect, which they never will, we should cease to laugh at all. Wisdom or knowledge—the study of our own thoughts or of those of others—has a tendency to alter our general views, and affects our appreciation of humour, even where it affords no special information on the subject before us. Upon given premises the conclusions of the highly cultivated are different from those of others; and intellectual humour is that which generally they enjoy most—finding more pleasure in thought than in emotion. No doubt they sometimes appreciate what is lighter, especially when a reaction taking place after severe study, they feel like children let out to play. But ordinarily they certainly appreciate most that rare and subtle humour which inferior minds cannot understand. Herbert Spencer is probably correct that "we enjoy that humour most at which we laugh least." But we must not conclude from this rule that we can at will by repressing our laughter increase our pleasure. The statement refers to the cases of different persons or of the same person under different circumstances. Rude and uneducated people would little feel the humour at which they could not laugh, and some grave people entirely miss much that is amusing. "The nervous energy," he says, "which would have caused muscular action, is discharged in thought," but this presupposes a very sensitive mental organization into which the discharge can be made. Where this does not exist, laughter accompanies the appreciation of humour, and in silence there would be little pleasure. The cause of mirth also differs as the persons affected, and the farce which creates a roar in the pit will often not raise a smile in the boxes. Swift writes—"Bombast and buffoonery, by nature lofty and light, soar highest of all in the theatre, and would be lost in the roof, if the prudent architect had not contrived for them a fourth place called the twelvepenny gallery and there planted a suitable colony." That emotionable ebullition affords a lower class less enjoyment than intellectual action gives a higher order of mind, must be somewhat uncertain. A thoughtful nature is probably happier than an emotional, but it is difficult to compare the pleasure derived from intellectual, moral, and sensuous feelings.

It is a common saying that "there is no disputing taste," and in this respect we allow every man a certain range. But when he transgresses this limit he often becomes ludicrous, especially to those whose tastes rather tend in the opposite direction. The strange figure and accoutrements of Don Quixote raised great laughter among the gay ladies at the inn, and induced the puissant knight-errant to administer to them the rebuke "Excessive laughter without cause denotes folly."

A friend of mine, desirous of giving an intellectual treat to the rustics in the neighbourhood, announced that a reading of Shakespeare would be given in the village schoolroom by a celebrated elocutionist. The villagers, attracted by the name, came in large numbers, and laughed vociferously at all the pathetic parts, but looked grave at the humour. This was, no doubt, partly owing to their habits of life, as well as to a want of taste and information. Taste for music, and familiarity with the traditional style of the Opera, enable us to enjoy dialogues in recitative, but were a man in ordinary conversation to deliver himself in musical cadences, or even in rhyme, we should consider him supremely ridiculous.

Translations have often exhibited very strange vagaries of taste. Thus, Castalio's rendering of "The Song of Solomon" is ludicrous from the use of diminutives.

"Mea columbula, ostende mihi tuum vulticulum.
Cerviculam habes Davidicæ turris similem—Cervicula quasi eburnea turricula, &c."

Beattie is severe upon Dryden's obtuseness in his translation of the "Iliad." "Homer," he says, "has been blamed for degrading his gods into mortals, but Dryden has made them blackguards.... If we were to judge of the poet by the translator, we should imagine the Iliad to have been partly designed for a satire upon the clergy."

Addison observes that the Ancients were not particular about the bearing of their similes. "Homer likens one of his heroes, tossing to and fro in his bed and burning with resentment, to a piece of flesh broiled on the coals." "The present Emperor of Persia," he continues, "conformable to the Eastern way of thinking, amidst a great many pompous titles, denominates himself the 'Son of Glory,' and 'Nutmeg of Delight.'" Eastern nations indulge in this kind of hyperbole, which seems to us rather to overstep the sublime, but we cannot be astonished when we read in the Zgand-Savai (Golden Tulip) of China, that "no one can be a great poet, unless he have the majestic carriage of the elephant, the bright eyes of the partridge, the agility of the antelope, and a face rivalling the radiance of the full moon."

Reflection is generally antagonistic to humour, just as abstraction of mind will prevent our feeling our hands being tickled. Often what was intended to amuse, merely produces thought on some social or physical question. But the variability of our appreciation of humour, is most commonly recognised in the differences of moral feeling. We have often heard people say that it is wrong for people to jest on this or that subject, or that they will not laugh at such ribaldry. The excitement necessary for the enjoyment of humour is then neutralized by deeper feelings, and they are perhaps more inclined to sigh than to laugh, or the nervous action being entirely dormant, they remain unaffected. But not only do people's feelings on various subjects differ in kind and in amount, but also in result. The same idea produces different emotions in different men, and the same emotion different effects. One man will regard an event as insignificant, and will not laugh at it; another will consider it important, but still will be unable to keep his countenance, where most men would be grave. The experience of daily life teaches us that different men act very differently under the same kind of emotion. The Ancients laughed at calamities, which would call forth our commiseration, their consideration for others not being so great, nor their appreciation of suffering so acute. But in the cases of some few individuals, and of barbarous nations, we sometimes find at the present day instances of the ludicrous seasoned with considerable hostility. Flögel tells us that he knew a man in Germany who took especial delight in witnessing tortures and executions, and related the circumstances attending them with the greatest enjoyment and laughter. In "Two Years in Fiji," we read, "Among the appliances which I had brought with me to Fiji, from Sydney, were a stethoscope and a scarifier. Nothing was considered more witty by those in the secret than to place this apparently harmless instrument on the back of some unsuspecting native, and touch the spring. In an instant twelve lancets would plunge into the swarthy flesh. Then would follow a long-drawn cry, scarcely audible amidst peals of laughter from the bystanders."

It has been said that our non-appreciation of hostile humour is much owing to the suppression of feeling in conventional society, but I think that there is also an influence in civilization, which subdues and directs our emotions. A certain difference in this respect can be traced in the higher and lower classes of the population. This, and the difference in reasoning power, have led to the observation that "the last thing in which a cultivated man can have community with the vulgar is in jocularity."

Jesting on religious subjects, has generally arisen from scepticism, deficiency in taste, or disbelief in the injurious consequences of the practice. Some consider that levity is likely to bring any subject it touches into contempt, or is only fitly used in connection with light subjects; while others regard it as merely a source of harmless pleasure, and can even laugh at a joke against themselves. In like manner some consider it inconsistent with the profession of religion to attend balls, races, or theatres, or even to wear gay-coloured clothes. Congreve has been blamed even for calling a coachman a "Jehu." On the other hand, at the beginning of this century, "a man of quality" could scarcely get through a sentence without some profane expletive. Sir Walter Scott makes a highwayman lament that, although he could "swear as round an oath as any man," he could never do it "like a gentleman." Lord Melbourne was so accustomed to garnish his conversation in this way that Sydney Smith once said to him, "We will take it for granted that everybody is damned, and now proceed with the subject." In former times, and even sometimes in our own day, the most eminent Christians have occasionally indulged in jest. At the time of the Reformation, a martyr comforted a fellow-sufferer, Philpot, by telling him he was a "pot filled with the most precious liquor;" and Latimer called bad passions "Turks," and bade his hearers play at "Christian Cards." "Now turn up your trump—hearts are trumps." Robert Hall, a most pious Christian, was constantly transgressing in this direction, and I have heard Mr. Moody raise a roar of laughter while preaching.
