The capacity for discerning the essential truth, in fact, is as rare among men as it is common among crows, bullfrogs and mackerel. The man who shows it is a man of quite extraordinary quality—perhaps even a man downright diseased. Exhibit a new truth of any natural plausibility before the great masses of men, and not one in ten thousand will suspect its existence, and not one in a hundred thousand will embrace it without a ferocious resistance. All the durable truths that have come into the world within historic times have been opposed as bitterly as if they were so many waves of smallpox, and every individual who has welcomed and advocated them, absolutely without exception, has been denounced and punished as an enemy of the race. Perhaps “absolutely without exception” goes too far. I substitute “with five or six exceptions.” But who were the five or six exceptions? I leave you to think of them; myself, I can’t.... But I think at once of Charles Darwin and his associates, and of how they were reviled in their time. This reviling, of course, is less vociferous than it used to be, chiefly because later victims are in the arena, but the underlying hostility remains. Within the past two years the principal Great Thinker of Britain, George Bernard Shaw, has denounced the hypothesis of natural selection to great applause, and a three-times candidate for the American Presidency, William Jennings Bryan, has publicly advocated prohibiting the teaching of it by law. The great majority of Christian ecclesiastics in both English-speaking countries, and with them the great majority of their catachumens, are still committed to the doctrine that Darwin was a scoundrel, and Herbert Spencer another, and Huxley a third—and that Nietzsche is to the three of them what Beelzebub himself is to a trio of bad boys. This is the reaction of the main body of respectable folk in two puissant and idealistic Christian nations to the men who will live in history as the intellectual leaders of the Nineteenth Century. This is the immemorial attitude of men in the mass, and of their chosen prophets, to whatever is honest, and important, and most probably true.
