Some confusion as to the nature of Humor has been created by the fact that those who have written most eloquently on it have dwelt almost exclusively on its higher forms, and have defined humor in general as the _sympathetic_ presentation of incongruous elements in human nature and life—a definition which only applies to its later development. A great deal of humor may coexist with a great deal of barbarism, as we see in the Middle Ages; but the strongest flavor of the humor in such cases will come, not from sympathy, but more probably from triumphant egoism or intolerance; at best it will be the love of the ludicrous exhibiting itself in illustrations of successful cunning and of the _lex talionis_ as in _Reineke Fuchs_, or shaking off in a holiday mood the yoke of a too exacting faith, as in the old Mysteries. Again, it is impossible to deny a high degree of humor to many practical jokes, but no sympathetic nature can enjoy them. Strange as the genealogy may seem, the original parentage of that wonderful and delicious mixture of fun, fancy, philosophy, and feeling, which constitutes modern humor, was probably the cruel mockery of a savage at the writhings of a suffering enemy—such is the tendency of things toward the good and beautiful on this earth! Probably the reason why high culture demands more complete harmony with its moral sympathies in humor than in wit, is that humor is in its nature more prolix—that it has not the direct and irresistible force of wit. Wit is an electric shock, which takes us by violence, quite independently of our predominant mental disposition; but humor approaches us more deliberately and leaves us masters of ourselves. Hence it is, that while coarse and cruel humor has almost disappeared from contemporary literature, coarse and cruel wit abounds; even refined men cannot help laughing at a coarse _bon mot_ or a lacerating personality, if the “shock” of the witticism is a powerful one; while mere fun will have no power over them if it jar on their moral taste. Hence, too, it is, that while wit is perennial, humor is liable to become superannuated.
