If the philosophers were in a position to discover the truth, who among them would take an interest in it? Each knows well that his system is no better founded that the others. But he maintains it because it is his. There is not a single one of them who, if he came to know the true and the false, would not prefer the lie he has found to the truth discovered by another. Where is the philosopher who would not gladly deceive mankind for his own glory? Where is the one who in the secrecy of his heart sets himself any other goal than that of distinguishing himself? Provided that he raises himself above the vulgar, provided that he dims the brilliance of his competitors, what more does he ask? The essential thing is to think differently from others. Among believers he is an atheist; among atheists he would be a believer.
Rousseau, Emile – Book IV
