§75M. Bayle continues thus: 'Every philosophical dispute assumes that the disputant parties agree on certain definitions' (This would be desirable, but usually it is only in the dispute itself that one reaches such a point, if the necessity arises.) 'and that they admit the rules of Syllogisms, and the signs for the recognition of bad arguments. After that everything lies in the investigation as to whether a thesis conforms mediately or immediately to the principles one is agreed upon' (which is done by means of the syllogisms of him who makes objections); 'whether the premisses of a proof (advanced by the opposer) 'are true; whether the conclusion is properly drawn; whether a four-term Syllogism has been employed; whether some aphorism of the chapter de oppositis or de sophisticis elenchis, etc., has not been violated.' (It is enough, putting it briefly, to deny some premiss or some conclusion, or finally to explain or get explained some ambiguous term.) 'One comes off victorious either by showing that the subject of dispute has no connexion with the principles which had been agreed upon' (that is to say, by showing that the objection proves nothing, and then the defender wins the case), 'or by reducing the defender to absurdity' (when all the premisses and all the conclusions are well proved). 'Now one can reduce him to that point either by showing him that the conclusions of his thesis are "yes" and "no" at once, or by constraining him to say only intelligible things in answer.' (This last embarrassment he can always avoid, because he has no need to advance new theses.) 'The aim in disputes of this kind is to throw light upon obscurities and to arrive at self-evidence.' (It is the aim of the opposer, for he wishes to demonstrate that the Mystery is false; but this cannot here be the aim of the defender, for in admitting Mystery he agrees that one cannot demonstrate it.) 'This leads to the opinion that during the course of the proceedings victory sides more or less with the defender or with the opposer, according to whether there is more or less clarity in the propositions of the one than in the propositions of the other.' (That [117] is speaking as if the defender and the opposer were equally unprotected; but the defender is like a besieged commander, covered by his defence works, and it is for the attacker to destroy them. The defender has no need here of self-evidence, and he seeks it not: but it is for the opposer to find it against him, and to break through with his batteries in order that the defender may be no longer protected.)

76. 'Finally, it is judged that victory goes against him whose answers are such that one comprehends nothing in them,' (It is a very equivocal sign of victory: for then one must needs ask the audience if they comprehend anything in what has been said, and often their opinions would be divided. The order of formal disputes is to proceed by arguments in due form and to answer them by denying or making a distinction.) 'and who confesses that they are incomprehensible.' (It is permitted to him who maintains the truth of a Mystery to confess that this mystery is incomprehensible; and if this confession were sufficient for declaring him vanquished there would be no need of objection. It will be possible for a truth to be incomprehensible, but never so far as to justify the statement that one comprehends nothing at all therein. It would be in that case what the ancient Schools called Scindapsus or Blityri (Clem. Alex., Stromateis, 8), that is, words devoid of meaning.) 'He is condemned thenceforth by the rules for awarding victory; and even when he cannot be pursued in the mist wherewith he has covered himself, and which forms a kind of abyss between him and his antagonists, he is believed to be utterly defeated, and is compared to an army which, having lost the battle, steals away from the pursuit of the victor only under cover of night.' (Matching allegory with allegory, I will say that the defender is not vanquished so long as he remains protected by his entrenchments; and if he risks some sortie beyond his need, it is permitted to him to withdraw within his fort, without being open to blame for that.)

§77I was especially at pains to analyse this long passage where M. Bayle has put down his strongest and most skilfully reasoned statements in support of his opinion: and I hope that I have shown clearly how this excellent man has been misled. That happens all too easily to the ablest and shrewdest persons when they give free rein to their wit without exercising the patience necessary for delving down to the very foundations of their systems. The details we have entered into here will serve as [118] answer to some other arguments upon the subject which are dispersed through the works of M. Bayle, as for instance when he says in his Reply to the Questions of a Provincial (vol. III, ch. 133, p. 685): 'To prove that one has brought reason and religion into harmony one must show not only that one has philosophic maxims favourable to our faith, but also that the particular maxims cast up against us as not being consistent with our Catechism are in reality consistent with it in a clearly conceived way.' I do not see that one has need of all that, unless one aspire to press reasoning as far as the how of the Mystery. When one is content to uphold its truth, without attempting to render it comprehensible, one has no need to resort to philosophic maxims, general or particular, for the proof; and when another brings up some philosophic maxims against us, it is not for us to prove clearly and distinctly that these maxims are consistent with our dogma, but it is for our opponent to prove that they are contrary thereto.

§78M. Bayle continues thus in the same passage: 'For this result we need an answer as clearly evident as the objection.' I have already shown that it is obtained when one denies the premisses, but that for the rest it is not necessary for him who maintains the truth of the Mystery always to advance evident propositions, since the principal thesis concerning the Mystery itself is not evident. He adds further: 'If we must make reply and rejoinder, we must never rest in our positions, nor claim that we have accomplished our design, so long as our opponent shall make answer with things as evident as our reasons can be.' But it is not for the defender to adduce reasons; it is enough for him to answer those of his opponent.

§79Finally the author draws the conclusion: 'If it were claimed that, on making an evident objection, a man has to be satisfied with an answer which we can only state as a thing possible though incomprehensible to us, that would be unfair.' He repeats this in the posthumous Dialogues, against M. Jacquelot, p. 69. I am not of this opinion. If the objection were completely evident, it would triumph, and the thesis would be overthrown. But when the objection is only founded on appearances or on instances of the most frequent occurrence, and when he who makes it desires to draw from it a universal and certain conclusion, he who upholds the Mystery may answer with the instance of a bare possibility. For such an instance [119] suffices to show that what one wished to infer from the premisses, is neither certain nor general; and it suffices for him who upholds the Mystery to maintain that it is possible, without having to maintain that it is probable. For, as I have often said, it is agreed that the Mysteries are against appearances. He who upholds the Mystery need not even adduce such an instance; and should he adduce it, it were indeed a work of supererogation, or else an instrument of greater confusion to the adversary.

§80There are passages of M. Bayle in the posthumous reply that he made to M. Jacquelot which seem to me still worthy of scrutiny. 'M. Bayle' (according to pp. 36, 37) 'constantly asserts in his Dictionary, whenever the subject allows, that our reason is more capable of refuting and destroying than of proving and building; that there is scarcely any philosophical or theological matter in respect of which it does not create great difficulties. Thus', he says, 'if one desired to follow it in a disputatious spirit, as far as it can go, one would often be reduced to a state of troublesome perplexity; and in fine, there are doctrines certainly true, which it disputes with insoluble objections.' I think that what is said here in reproach of reason is to its advantage. When it overthrows some thesis, it builds up the opposing thesis. And when it seems to be overthrowing the two opposing theses at the same time, it is then that it promises us something profound, provided that we follow it as far as it can go, not in a disputatious spirit but with an ardent desire to search out and discover the truth, which will always be recompensed with a great measure of success.
