44. Now we have no need of revealed faith to know that there is such a sole Principle of all things, entirely good and wise. Reason teaches us this by infallible proofs; and in consequence all the objections taken from the course of things, in which we observe imperfections, are only based on false appearances. For, if we were capable of understanding the universal harmony, we should see that what we are tempted to find fault with is connected with the plan most worthy of being chosen; in a word, we _should see_, and should not _believe_ only, that what God has done is the best. I call 'seeing' here what one knows _a priori_ by the causes; and [99] 'believing' what one only judges by the effects, even though the one be as certainly known as the other. And one can apply here too the saying of St. Paul (2 Cor. v. 7), that we walk by _faith_ and not by _sight_. For the infinite wisdom of God being known to us, we conclude that the evils we experience had to be permitted, and this we conclude from the effect or _a posteriori_, that is to say, because they exist. It is what M. Bayle acknowledges; and he ought to content himself with that, and not claim that one must put an end to the false appearances which are contrary thereto. It is as if one asked that there should be no more dreams or optical illusions. 45. And it is not to be doubted that this faith and this confidence in God, who gives us insight into his infinite goodness and prepares us for his love, in spite of the appearances of harshness that may repel us, are an admirable exercise for the virtues of Christian theology, when the divine grace in Jesus Christ arouses these motions within us. That is what Luther aptly observed in opposition to Erasmus, saying that it is love in the highest degree to love him who to flesh and blood appears so unlovable, so harsh toward the unfortunate and so ready to condemn, and to condemn for evils in which he appears to be the cause or accessary, at least in the eyes of those who allow themselves to be dazzled by false reasons. One may therefore say that the triumph of true reason illumined by divine grace is at the same time the triumph of faith and love. 46. M. Bayle appears to have taken the matter quite otherwise: he declares himself against reason, when he might have been content to censure its abuse. He quotes the words of Cotta in Cicero, where he goes so far as to say that if reason were a gift of the gods providence would be to blame for having given it, since it tends to our harm. M. Bayle also thinks that human reason is a source of destruction and not of edification (_Historical and Critical Dictionary_, p. 2026, col. 2), that it is a runner who knows not where to stop, and who, like another Penelope, herself destroys her own work. _Destruit, aedificat, mutat quadrata rotundis._
