With regard to contradictions, for instance, no one whose mind is free from theological preoccupations can do other than admit the irreconcilable divergences between the synoptists and the author of the Fourth Gospel, and between the synoptists Compared with one another. For us rationalists this is not of much importance; but the orthodox reasoner, compelled to be of opinion that his book is right in every particular, finds himself involved in endless subtleties. Silvestre de Sacy was very much perplexed by the quotations from the Old Testament which are met with in the New. He found it so difficult, with his predilection for accuracy in quotations, to reconcile them that he eventually admitted as a principle that the two Testaments are both infallible of themselves, but that the New Testament is not so when it quotes the Old. Only those who have no sort of experience in the ways of religion will feel any surprise that men of such great powers of application should have clung to such untenable positions. In these shipwrecks of a faith upon which you have centred your life, you cling to the most unlikely means of salvage rather than allow all you cherish to go to the bottom. Men of the world who believe that people are brought to a decision in the choice of their opinions by reasons of sympathy or antipathy will no doubt be surprised at the train of reasoning which alienated me from the Christian faith, to which I had so many motives, both of interest and inclination, for remaining attached. Those who have not the scientific spirit can scarcely understand that one's opinions are formed outside of one by a sort of impersonal concretion of which one is, so to speak, the spectator. In thus letting my course be shaped by the force of events, I believed myself to be conforming to the rules of the seventeenth century school, especially to those of Malebranche, whose first principle is that reason should be contemplated, that man has no part in its procreation, and that his sole duty is to stand before the truth, free from all personal bias, ready to let himself be led whither the balance of demonstration wills it. So far from having at the outset certain results in view, these illustrious thinkers urged in the interests of the truth the obliteration of anything like a wish, a tendency, or a personal attachment. The great reproach of the preachers of the seventeenth century against the libertines was that they had embraced their desires and had adopted irreligious opinions because they wished them to be true.
