…they have a certain reverence for the old because it is old. They think a man is better for being dead, especially if he has been dead a long time. They think the fathers of their nation were the greatest and best of all mankind. All these things they implicitly believe because it is popular and patriotic, and because they were told so when they were very small, and remember distinctly of hearing mother read it out of a book. It is hard to over-estimate the influence of early training in the direction of superstition. You first teach children that a certain book is true – that it was written by God himself – that to question its truth is a sin, that to deny it is a crime, and that should they die without believing that book they will be forever damned without benefit of clergy. The consequence is, that long before they read that book, they believe it to be true. When they do read it their minds are wholly unfitted to investigate its claims. They accept it as a matter of course.
In this way the reason is overcome, the sweet instincts of humanity are blotted from the heart, and while reading its infamous pages even justice throws aside her scales, shrieking for revenge, and charity, with bloody hands, applauds a deed of murder. In this way we are taught that the revenge of man is the justice of God; that mercy is not the same everywhere. In this way the ideas of our race have been subverted. In this way we have made tyrants, bigots, and inquisitors. In this way the brain of man has become a kind of palimpsest upon which, and over the writings of nature, superstition has scrawled her countless lies. One great trouble is that most teachers are dishonest. They teach as certainties those things concerning which they entertain doubts. They do not say, “We think this is so,” but “We know this is so.” They do not appeal to the reason of the pupil, but they command his faith. They keep all doubts to themselves; they do not explain, they assert. All this is infamous. In this way you may make Christians, but you cannot make men; you cannot make women. You can make followers, but no leaders; disciples, but no Christs. You may promise power, honor, and happiness to all those who will blindly follow, but you cannot keep your promise.
