, V: "Ad Imaginem Dei Creavit Illum," § 3: "Meditation on Meditation":
Man's natural instinct, in fact, is never toward what is sound and true; it is toward what is specious and false. Let any great nation of modern times be confronted by two conflicting propositions, the one grounded upon the utmost probability and reasonableness and the other upon the most glaring error, and it will almost invariably embrace the latter. It is so in politics, which consists wholly of a succession of unintelligent crazes, many of them so idiotic that they exist only as battle-cries and shibboleths and are not reducible to logical statement at all. It is so in religion, which, like poetry, is simply a concerted effort to deny the most obvious
realities. It is so in nearly every field of thought. The ideas that conquer the race most rapidly and arouse the wildest enthusiasm and are held most tenaciously are precisely the ideas that are most insane. This has been true since the first "advanced" gorilla put on underwear, cultivated a frown and began his first lecture tour in the first chautauqua, and it will be so until the high gods, tired of the farce at last, obliterate the race with one great, final blast of fire, mustard gas and streptococci.
Man is the yokel par excellence, the booby unmatchable, the king dupe of the cosmos. He is chronically and inescapably deceived, not only by the other animals and by the delusive face of nature herself, but also and more particularly by himself—by his incomparable talent for searching out and embracing what is false, and for overlooking and denying what is true.
But if truth thus has hard sledding, error is given a loving welcome. The man who invents a new imbecility is hailed gladly, and bidden to make himself at home; he is, to the great masses of men, the beau idéal of mankind. Go back through the history of the past thousand years and you will find that nine-tenths of the popular idols of the world—not the heroes of small sects, but the heroes of mankind in the mass—have been merchants of palpable nonsense. It has been so in politics, it has been so in religion, and it has been so in every other department of human thought. Every such hawker of the not-true has been opposed, in his time, by critics who denounced and refuted him; his contention has been disposed of immediately it was uttered. But on the side of every one there has been the titanic force of human credulity, and it has sufficed in every case to destroy his foes and establish his immortality.
