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. But we have not spoken of pleasure as a whole, pleasure apart from entertainment, play and humor. The satisfaction of any physical desire is pleasant, so that to eat and drink and have sexual relations become great pleasure trends. There are some who live only for these pleasures, ranging from glutton to epicure, from the brutally passionate to the sexual connoisseur. Others whose appetites are hearty subordinate them to the main business of their lives, achievement in some form. There is a whole range of taste in pleasures of this kind that I do not even attempt to analyze at this point, even if it were possible for me to analyze it.
