25. But these writers have not denied the possibility of finding thread in the labyrinth; they have recognized the difficulty, but they have surely not turned difficulty into sheer impossibility. As for me, I confess that I cannot agree with those who maintain that a truth can admit of irrefutable objections: for is an objection anything but an argument whose conclusion contradicts our thesis? And is not an irrefutable argument a demonstration? And how can one know the certainty of demonstrations except by examining the argument in detail, the form and the matter, in order to see if the form is good, and then if each premiss is either admitted or proved by another argument of like force, until one is able to make do with admitted premisses alone? Now if there is such an objection against our thesis we must say that the falsity of this thesis is demonstrated, and that it is impossible for us to have reasons sufficient to prove it; otherwise two contradictories would be true at once. One must always yield to proofs, whether they be proposed in positive form or advanced in the shape of objections. And it is wrong and fruitless to try to weaken opponents' proofs, under the pretext that they are only objections, since the opponent can play the same game and can reverse the denominations, exalting his arguments by naming them 'proofs' and sinking ours under the blighting title of 'objections'.
26. It is another question whether we are always obliged to examine the objections we may have to face, and to retain some doubt in respect of our own opinion, or what is called formido oppositi, until this examination has been made. I would venture to say no, for otherwise one would never attain to certainty and our conclusion would be always provisional. I believe that able geometricians will scarce be troubled by the objections of Joseph Scaliger against Archimedes, or by those of Mr. Hobbes against Euclid; but that is because they have fully understood and are sure of the proofs. Nevertheless it is sometimes well to show oneself ready to examine certain objections. On the one hand it may serve to rescue people from their error, while on the other we ourselves may profit by it; for specious fallacies often contain some useful solution and bring about the removal of considerable difficulties. That is why I have always liked ingenious objections made against my own opinions, and I have never examined them without profit: witness those which M. Bayle formerly made against my System of Pre-established Harmony, not to mention those which M. Arnauld, M. l'Abbé Foucher and Father Lami, O.S.B., made to me on the same subject. But to return to the principal question, I conclude from reasons I have just set forth that when an objection is put forward against some truth, it is always possible to answer it satisfactorily.
27. It may be also that M. Bayle does not mean 'insoluble objections' in the sense that I have just explained. I observe that he varies, at least in his expressions: for in his posthumous Reply to M. le Clerc he does not admit that one can bring demonstrations against the truths of faith. It appears therefore that he takes the objections to be insoluble only in respect of our present degree of enlightenment; and in this Reply, p. 35, he even does not despair of the possibility that one day a solution hitherto unknown may be found by someone. Concerning that more will be said later. I hold an opinion, however, that will perchance cause surprise, namely that this solution has been discovered entire, and is not even particularly difficult. Indeed a mediocre intelligence capable of sufficient care, and using correctly the rules of common logic, is in a position to answer the most embarrassing objection made against truth, when the objection is only taken from reason, and when it is claimed to be a 'demonstration'. Whatever scorn the generality of moderns have to-day for the logic of Aristotle, one must acknowledge that it teaches infallible ways of resisting error in these conjunctures. For one has only to examine the argument according to the rules and it will always be possible to see whether it is lacking in form or whether there are premisses such as are not yet proved by a good argument.
28. It is quite another matter when there is only a question of probabilities, for the art of judging from probable reasons is not yet well established; so that our logic in this connexion is still very imperfect, and to this very day we have little beyond the art of judging from demonstrations. But this art is sufficient here: for when it is a question of opposing reason to an article of our faith, one is not disturbed by objections that only attain probability. Everyone agrees that appearances are against Mysteries, and that they are by no means probable when regarded only from the standpoint of reason; but it suffices that they have in them nothing of absurdity. Thus demonstrations are required if they are to be refuted.
29. And doubtless we are so to understand it when Holy Scripture warns us that the wisdom of God is foolishness before men, and when St. Paul observed that the Gospel of Jesus Christ is foolishness unto the Greeks, as well as unto the Jews a stumbling-block. For, after all, one truth cannot contradict another, and the light of reason is no less a gift of God than that of revelation. Also it is a matter of no difficulty among theologians who are expert in their profession, that the motives of credibility justify, once for all, the authority of Holy Scripture before the tribunal of reason, so that reason in consequence gives way before it, as before a new light, and sacrifices thereto all its probabilities. It is more or less as if a new president sent by the prince must show his letters patent in the assembly where he is afterwards to preside. That is the tendency of sundry good books that we have on the truth of religion, such as those of Augustinus Steuchus, of Du Plessis-Mornay or of Grotius: for the true religion must needs have marks that the false religions have not, else would Zoroaster, Brahma, Somonacodom and Mahomet be as worthy of belief as Moses and Jesus Christ. Nevertheless divine faith itself, when it is kindled in the soul, is something more than an opinion, and depends not upon the occasions or the motives that have given it birth; it advances beyond the intellect, and takes possession of the will and of the heart, to make us act with zeal and joyfully as the law of God commands. Then we have no further need to think of reasons or to pause over the difficulties of argument which the mind may anticipate.
30. Thus what we have just said of human reason, which is extolled and decried by turns, and often without rule or measure, may show our lack of exactitude and how much we are accessary to our own errors. Nothing would be so easy to terminate as these disputes on the rights of faith and of reason if men would make use of the commonest rules of logic and reason with even a modicum of attention. Instead of that, they become involved in oblique and ambiguous phrases, which give them a fine field for declamation, to make the most of their wit and their learning. It would seem, indeed, that they have no wish to see the naked truth, peradventure because they fear that it may be more disagreeable than error: for they know not the beauty of the Author of all things, who is the source of truth.
31. This negligence is a general defect of humanity, and one not to be laid to the charge of any particular person. Abundamus dulcibus vitiis, as Quintilian said of the style of Seneca, and we take pleasure in going astray. Exactitude incommodes us and rules we regard as puerilities. Thus it is that common logic (although it is more or less sufficient for the examination of arguments that tend towards certainty) is relegated to schoolboys; and there is not even a thought for a kind of logic which should determine the balance between probabilities, and would be so necessary in deliberations of importance. So true is it that our mistakes for the most part come from scorn or lack of the art of thinking: for nothing is more imperfect than our logic when we pass beyond necessary arguments. The most excellent philosophers of our time, such as the authors of The Art of Thinking, of The Search for Truth and of the Essay concerning Human Understanding, have been very far from indicating to us the true means fitted to assist the faculty whose business it is to make us weigh the probabilities of the true and the false: not to mention the art of discovery, in which success is still more difficult of attainment, and whereof we have nothing beyond very imperfect samples in mathematics.
32. One thing which might have contributed most towards M. Bayle's belief that the difficulties of reason in opposition to faith cannot be obviated is that he seems to demand that God be justified in some such manner as that commonly used for pleading the cause of a man accused before his judge. But he has not remembered
