74. 'Now it is certain', so M. Bayle continues, 'that an objection which is founded on distinct notions remains equally victorious, whether you give to it no answer, or you make an answer where none can comprehend anything. Can the contest be equal between a man who alleges in objection to you that which you and he very clearly conceive, and you, who can only defend yourself by answers wherein neither of you understands anything?' (It is not enough that the objection be founded on quite distinct notions, it is necessary also that one apply it in contradiction of the thesis. And when I answer someone by denying some premiss, in order to compel him to prove it, or some conclusion, to compel him to put it in good form, it cannot be said that I answer nothing or that I answer nothing intelligible. For as it is the doubtful premiss of the adversary that I deny, my denial will be [116] as intelligible as his affirmation. Finally, when I am so obliging as to explain myself by means of some distinction, it suffices that the terms I employ have some meaning, as in the Mystery itself. Thus something in my answer will be comprehended: but one need not of necessity comprehend all that it involves; otherwise one would comprehend the Mystery also.) 75. M. 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,
