"What my sect teaches is obscure, I admit it," says a fanatic; "and it is because of this obscurity that it must be believed; for the sect itself says it is full of obscurities. My sect is extravagant, therefore it is divine; for how should what appears so mad have been embraced by so many peoples, if it were not divine?" It is precisely like the Alcoran which the Sonnites say has an angel's face and an animal's snout; be not scandalized by the animal's snout, and worship the angel's face. Thus speaks this insensate fellow. But a fanatic of another sect answers--"It is you who are the animal, and I who am the angel." Well, who shall judge the suit? who shall decide between these two fanatics? The reasonable, impartial man learned in a knowledge that is not that of words; the man free from prejudice and lover of truth and justice; in short, the man who is not the foolish animal, and who does not think he is the angel. SECTION II _Sect_ and _error_ are synonymous. You are Peripatetic and I Platonician; we are therefore both wrong; for you combat Plato only because his fantasies have revolted you, and I am alienated from Aristotle only because it seems to me that he does not know what he is talking about. If one or the other had demonstrated the truth, there would be a sect no longer. To declare oneself for the opinion of the one or the other is to take sides in a civil war. There are no sects in mathematics, in experimental physics. A man who examines the relations between a cone and a sphere is not of the sect of Archimedes: he who sees that the square of the hypotenuse of a right-angled triangle is equal to the square of the two other sides is not of the sect of Pythagoras. When you say that the blood circulates, that the air is heavy, that the sun's rays are pencils of seven refrangible rays, you are not either of the sect of Harvey, or the sect of Torricelli, or the sect of Newton; you agree merely with the truth demonstrated by them, and the entire universe will ever be of your opinion. This is the character of truth; it is of all time; it is for all men; it has only to show itself to be recognized; one cannot argue against it. A long dispute signifies--"Both parties are wrong." FOOTNOTES: [20] Reference to the Abbe Houtteville, author of a book entitled--"The Truth of the Christian Religion, Proved by the Facts." _SELF-ESTEEM_ Nicole in his "Essais de Morale," written after two or three thousand volumes of ethics ("Treatise on Charity," Chap. II), says that "by means of the wheels and gibbets which people establish in common are repressed the tyrannous thoughts and designs of each individual's self-esteem."
