When we seek one who is the cause of wit in other men we pass by the jovial Falstaff and come to the preternaturally serious Don Quixote. Here we have not the chance outcropping of "the lighter vein," but the mother lode which the humorist finds inexhaustible. Don Quixote, with a lofty gravity which never for an instant relaxes, sets forth upon his mission. His is a soul impenetrable to mirth; but as he rides he enlivens the whole country-side. Everywhere merry eyes are watching him; boisterous laughter comes from the stables of village inns; from castle windows high-born ladies smile upon him; the peasants in the fields stand gaping and holding their sides; the countenances of the priests relax, and even the robbers salute the knight with mock courtesy. The dullest La Manchan is refreshed, and feels that he belongs to a choice coterie of wits.

Cervantes tells us that he intended only a burlesque on the books of chivalry which were in vogue in his day. Had he done no more than he intended, he would have amused his own generation and then have been forgotten. It would be too much to ask that we should read the endless tales about Amadis and Orlando, only that we might appreciate his clever parody of them. A satire lasts no longer than its object. It must shoot folly as it flies. To keep on shooting at a folly after it is dead is unsportsmanlike.

But though we have not read the old books of chivalry, we have all come in contact with Quixotism. I say we have all come in contact with it; but let no selfish, conventional persons be afraid lest they catch it. They are immune. They may do many foolish things, but they cannot possibly be quixotic. Quixotism is a malady possible only to generous minds.

Listen to Don Quixote as he makes his plea before the duke and duchess. "I have redressed grievances, righted the injured, chastised the insolent, vanquished giants. My intentions have all been directed toward virtuous ends and to do good to all mankind. Now judge, most excellent duke and duchess, whether a person who makes it his study to practice all this deserves to be called a fool."

Our first instinct is to answer confidently, "Of course not! Such a character as you describe is what we call a hero or a saint." But the person whose moral enthusiasm has been tempered with a knowledge of the queer combinations of goodness and folly of which human nature is capable is more wary, and answers, "That depends."

In the case of Don Quixote it depends very much on the kind of world he lives in. If it should happen that in this world there are giants standing truculently at their castle doors, and forlorn maidens at every cross-roads waiting to be rescued, we will grant him the laurels that are due to the hero. But if La Mancha should not furnish these materials for his prowess,—then we must take a different view of the case.

The poor gentleman is mad, that is what the curate and the barber say; but when we listen to his conversation we are in doubt. If the curate could discourse half so eloquently he would have been a bishop long before this. The most that can be said is that he has some notions which are not in accordance with the facts, and that he acts accordingly; but if that were a proof of madness there would not be enough sane persons in the world to make strait-jackets for the rest. His chief peculiarity is that he takes himself with a seriousness that is absolute. All of us have thoughts which would not bear the test of strict examination. There are vagrant fancies and random impulses which, fortunately for our reputations, come to nothing. We are just on the verge of doing something absurd when we recognize the character of our proposed action; and our neighbors lose a pleasure. We comfort ourselves by the reflection that their loss is our gain. Don Quixote has no such inhibition; he carries out his own ideas to their logical conclusion.

The hero of Cervantes had muddled his wits by the reading of romances. Almost any kind of printed matter may have the same effect if one is not able to distinguish between what he has read and what he has actually experienced. One may read treatises on political economy until he mistakes the "economic man" who acts only according to the rules of enlightened self-interest for a creature of flesh and blood. One may read so many articles on the Rights of Women that he mistakes a hard-working American citizen who spends his summer in a down-town office, in order that his wife and daughter may go to Europe, for that odious monster the Tyrant Man. It is possible to read the Society columns of the daily newspapers till the reader does not know good society when he sees it. An estimable teacher in the public schools may devote herself so assiduously to pedagogical literature that she mistakes her school-room for a psychological laboratory, with results that are sufficiently tragical. There are excellent divines so learned in the history of the early church that they believe that semi-pelagianism is still the paramount issue. There were few men whose minds were, in general, better balanced than Mr. Gladstone's, yet what a fine example of Quixotism was that suggested by Queen Victoria's remark: "Mr. Gladstone always addresses me as if I were a public meeting." To address a woman as if she were a public meeting is the mistake of one who had devoted himself too much to political speeches.

A thoroughly healthy mind can endure a good deal of reading and a considerable amount of speculation with impunity. It does not take the ideas thus derived too seriously. It is continually making allowances, and every once in a while there is a general clearance. It is like a gun which expels the old cartridge as the new shot is fired. When the delicate mechanism for the expulsion of exploded opinions gets out of order the mind becomes the victim of "fixed ideas." The best idea becomes dangerous when it gets stuck. When the fixed ideas are of a noble and disinterested character we have a situation which excites at once the admiration of the moralist and the apprehension of the alienist. Perhaps this border-land between spiritual reality and intellectual hallucination belongs neither to the moralist nor to the alienist, but to the wise humorist. He laughs, but there is no bitterness or scorn in his laughter. It is mellow and human-hearted.

The world is full of people who have a faculty which enables them to believe whatever they wish. Thought is not, for them, a process which may go on indefinitely, a work in which they are collaborating with the universe. They do it all by themselves. It is the definite transaction of making up their minds. When the mind is made up it closes with a snap. After that, for an unwelcome idea to force an entrance would be a well-nigh impossible feat of intellectual burglary.
