With shame I confess it, Dr. Young's "Night Thoughts" have given me as many hearty laughs as any humorous book I ever read.

Men of one idea,—that is, who have one idea at a time,—men who accomplish great results, men of action, reformers, saints, martyrs, are inevitably destitute of humor; and if the idea that inspires them be great and noble, they are impervious to it. But through the perversity of human affairs it not infrequently happens that men are possessed by a single idea, and that a small and rickety one—some seven months' child of thought—that maintains a querulous struggle for life, sometimes to the disquieting of a whole neighborhood. These last commonly need no satirist, but, to use a common phrase, make themselves absurd, as if Nature intended them for parodies on some of her graver productions. For example, how could the attempt to make application of mystical prophecy to current events be rendered more ridiculous than when we read that two hundred years ago it was a leading point in the teaching of Lodowick Muggleton, a noted heresiarch, "that one John Robins was the last great antichrist and son of perdition spoken of by the Apostle in Thessalonians"? I remember also an eloquent and distinguished person who, beginning with the axiom that all the disorders of this microcosm, the body, had their origin in diseases of the soul, carried his doctrine to the extent of affirming that all derangements of the macrocosm likewise were due to the same cause. Hearing him discourse, you would have been well-nigh persuaded that you had a kind of complicity in the spots upon the sun, had he not one day condensed his doctrine into an epigram which made it instantly ludicrous. "I consider myself," exclaimed he, "personally responsible for the obliquity of the earth's axis." A prominent Come-outer once told me, with a look of indescribable satisfaction, that he had just been kicked out of a Quaker meeting. "I have had," he said, "Calvinistic kicks and Unitarian kicks, Congregational, Presbyterian, and Episcopalian kicks, but I never succeeded in getting a Quaker kick before." Could the fanaticism of the collectors of worthless rarities be more admirably caricatured than thus unconsciously by our passive enthusiast?

I think no one can go through a museum of natural curiosities, or see certain animals, without a feeling that Nature herself has a sense of the comic. There are some donkeys that one can scarce look at without laughing (perhaps on Cicero's principle of the haruspex haruspicem) and feeling inclined to say, "My good fellow, if you will keep my secret I will keep yours." In human nature, the sense of the comic seems to be implanted to keep man sane, and preserve a healthy balance between body and soul. But for this, the sorcerer Imagination or the witch Enthusiasm would lead us an endless dance.

The advantage of the humorist is that he cannot be a man of one idea—for the essence of humor lies in the contrast of two. He is the universal disenchanter. He makes himself quite as much the subject of ironical study as his neighbor. Is he inclined to fancy himself a great poet, or an original thinker, he remembers the man who dared not sit down because a certain part of him was made of glass, and muses smilingly, "There are many forms of hypochondria." This duality in his mind which constitutes his intellectual advantage is the defect of his character. He is futile in action because in every path he is confronted by the horns of an eternal dilemma, and is apt to come to the conclusion that nothing is very much worth the while. If he be independent of exertion, his life commonly runs to waste. If he turn author, it is commonly from necessity; Fielding wrote for money, and "Don Quixote" was the fruit of a debtors' prison.

It seems to be an instinct of human nature to analyze, to define, and to classify. We like to have things conveniently labelled and laid away in the mind, and feel as if we knew them better when we have named them. And so to a certain extent we do. The mere naming of things by their appearance is science; the knowing them by their qualities is wisdom; and the being able to express them by some intense phrase which combines appearance and quality as they affect the imagination through the senses by impression, is poetry. A great part of criticism is scientific, but as the laws of art are only echoes of the laws of nature, it is possible in this direction also to arrive at real knowledge, or, if not so far as that, at some kind of classification that may help us toward that excellent property—compactness of mind.

Addison has given the pedigree of humor: the union of truth and goodness produces wit; that of wit with wrath produces humor. We should say that this was rather a pedigree of satire. For what trace of wrath is there in the humor of Chaucer, Shakespeare, Rabelais, Cervantes, Sterne, Fielding, or Thackeray? The absence of wrath is the characteristic of all of them. Ben Jonson says that

When some one peculiar quality
Doth so possess a man that it doth draw
All his affects, his spirits, and his powers
In their constructions all to run one way,
This may be truly said to be a humor.

But this, again, is the definition of a humorous character,—of a good subject for the humorist,—such as Don Quixote, for example.

Humor—taken in the sense of the faculty to perceive what is humorous, and to give it expression—seems to be greatly a matter of temperament. Hence, probably, its name. It is something quite indefinable, diffused through the whole nature of the man; so that it is related of the great comic actors that the audience begin to laugh as soon as they show their faces, or before they have spoken a word.

The sense of the humorous is certainly closely allied with the understanding, and no race has shown so much of it on the whole as the English, and next to them the Spanish—both inclined to gravity. Let us not be ashamed to confess that, if we find the tragedy a bore, we take the profoundest satisfaction in the farce. It is a mark of sanity. Humor, in its highest level, is the sense of comic contradiction which arises from the perpetual comment which the understanding makes upon the impressions received through the imagination. Richter, himself, a great humorist, defines it thus:
