In the lower ranks this interchange, which is surprisingly frequent, is coarse and insulting. It is supposed to be a test of character to be able to "stand" these attacks with equanimity and even to join in the laugh against oneself. To "kid" and take "kidding" is thus an important social trait.
Humor is often used to expose the folly of the pretentious. Much of the stock in trade of the humorist lies in his attack on the pedant, the pompous, the great, the new-rich, the over-important of one kind or another. To find them less than they pretend to be gives two especial kinds of pleasure to the audience; the first the stripping away of disguise (Bergson), and the second the relief of our own feeling of inferiority in their presence by showing how inferior they really are.
Since inhibition wears on us, the great inhibitions are directly attacked by the humorist. Thus sex forms one of the great subjects of humor, and from the obscene story told by those on whom the sex inhibitions rest lightly to the joke about clothes, etc., told by those who mock the opposite sex, the whole idea is to bring about pleasure in the release of inhibitton and the play of the mind around the forbidden. Freud has some interesting remarks on this type of humor, which he regards largely as sexual aggression. It is necessary to say that the release of inhibition is always that of an inhibition not too strongly felt or accepted. A really modest person, one to whom the sex code is a sacred thing, does not find pleasure in a crude sex joke.
Similarly with the inhibition surrounding marriage, which is a stock subject of humor. The overearnest person dislikes this type of humor and reacts against it by calling it "in bad taste." In the Middle Ages (and to-day among those opposed to the Catholic church), the priest and nun were slyly or coarsely attacked by the humorist, and in all times those somewhat skeptical find in religion, its ceremonials and customs, a field for joke and satire.
The most interesting of the types of humor flirts with the disagreeable. Man is the only animal foreseeing death and disaster, and he not only quakes in the knowledge of misfortune, but also he jokes about it. It may be that the excitement of approaching in spirit the disagreeable is pleasant, and perhaps there is pleasure in attacking disaster, even in a playful way.
The ability to joke about other people's misfortunes is not, of course, a measure of gallantry or courage and usually indicates a feeling of superiority such as we all tend to feel in the presence of the unfortunate, even where no element of weakness has caused their mishap. But to joke about one's own troubles, danger and disaster at least indicate a sense of proportion, an ability to stand aloof from oneself.
This propensity is remarkably manifest in hospitals, in war and wherever disaster or danger is present. The soldiers nickname in a familiar way all their troubles and all their dangers. The popular phrases for dying illustrate this,--croaked, flew up the spout, turned up the toes, etc. In the war the different kinds of guns and missiles had nicknames, and puns were made on the various dreaded results of injury. It was declared by the soldiers that no missile could injure any man unless it has his name and address on it, which is, of course, a poetical, humorous comparison of the missile to a longed-for letter. I heard a wounded man say the only trouble was that the postoffice department mistook him for another fellow. Grim humor always is evident in grim situations; it is a way of evasion and escape, and also it is a challenge.
When one objectifies himself so that he sees himself, his purposes and his weaknesses in the light in which others might see him and find him "funny," then he has reached the heights in humor. Certain people are notoriously lacking in this quality of detachment, and they cannot laugh at themselves or find any humor in a situation that annoys, mortifies or hurts them. Others have it to a remarkable degree, and if they possess at the same time the art of telling the humorous story about themselves, they become very popular. This popularity accounts for a good deal of seeming modesty and humorous self-depiction; it is a sort of recompense for the self-confessed foible and weakness; it is a way of seeking the good opinion and applause of others and is sometimes sought to a ridiculous extreme.
The character and the state of culture stand revealed in the type of humor enjoyed. If a man laughs heartily at sex jokes, one may at least say, that while he may live up to the conventions in this matter, it is certain that he regards the inhibitions as conventions, even though he give them lip-homage. No one finds much humor in the things he holds as really sacred, and if these are attacked in the joke he may laugh, but he is offended and angry at heart. Any man permits a joke on women in general, but he will not permit an obscene joke about his wife or his mother.
Humor must not arouse the anger of the audience or the reader, and in this it resembles wrestling matches and friendly boxing, which are pleasant as attacks not seriously intended, but the blows must not exceed a certain play limit or war is declared.
To be entertained, to entertain, to escape from fatigue, monotony, inhibition, to seek excitement, to while away the time and thus to escape from failure, regret and sorrow are parts of the life and character of all. They who have nothing else but these activities in their lives are to be pitied, and they are unwise who allow themselves too little amusement and recreation.
