foundation has been or will be reached except through criticism; and all criticism implies and engenders doubt. A man who has never experienced, nay, I will say who is not constantly reiterating, the process of criticism, is a man who has no right to his enthusiasm. For he has won it at the cost of drugging his mind with passion; and that I maintain is a bad and wrong thing. I maintain it to be bad and wrong in itself, and quite apart from any consequences it may produce; for it is a primary duty to seek what is true and eschew what is false. But even from the secondary point of view of consequences, I have the gravest doubts as to the common assumption that the effects of enthusiasm are always preponderantly if not wholly good. When I consider, for example, the history of religion, I find no warrant for affirming that its services have outweighed its disservices. Jesus Christ, the greatest and, I think, the sanest of enthusiasts, lit the fires of the Inquisition and set up the Pope at Rome. Mahomet deluged the earth with blood, and planted the Turk on the Bosphorus. Saint Frances created a horde of sturdy beggars. Luther declared the Thirty Years War. Criticism would have arrested the course of these men; but would the world have been the worse? I doubt it. There would have been less heat; but there might have been more light. And, for my part, I believe in light. It may, indeed, be true that intellect without passion is barren; but it is certain that passion without intellect is mischievous. And since these powers, which should be united, are, in fact, at war in the great duel which runs through history, I take my stand with the intellect. If I must choose, I would rather be barren than mischievous. But it is my aim to be fruitful and to be fruitful through criticism. That means, I fear, that I am bound to make myself unpleasant to everybody. But I do it, not of malice prepense, but as in duty bound. You will say, perhaps, that that only makes the matter worse. Well, so be it! I will apologize no more, but proceed at once to my disagreeable task.
