Book I Chaptert 33

We must also observe that of all the arguments aforesaid it is easier with some to see why and where the reasoning leads the hearer astray, while with others it is more difficult, though often they are the same arguments as the former. For we must call an argument the same if it depends upon the same point; but the same argument is apt to be thought by some to depend on diction, by others on accident, and by others on something else, because each of them, when worked with different terms, is not so clear as it was. Accordingly, just as in fallacies that depend on ambiguity¹, which are generally thought to be the silliest form of fallacy, some are clear even to the man in the street (for humorous phrases nearly all depend on diction; e.g. ‘The man got the cart down from the stand’; and ‘Where are you bound?’ ‘To the yard arm’; and ‘Which cow will calve afore?’ ‘Neither, but both behind;’ and ‘Is the North wind clear?’ ‘No, indeed; for it has murdered the beggar and the merchant.” Is he a Good enough-King?’ ‘No, indeed; a Rob-son’: and so with the great majority of the rest as well), while others appear to elude² the most expert (and it is a symptom of this that they often fight about their terms, e.g. whether the meaning of ‘Being’ and ‘One’ is the same in all their applications or different; for some think that ‘Being’ and ‘One’ mean the same; while others solve the argument of Zeno and Parmenides by asserting that ‘One’ and ‘Being’ are used in a number of senses), likewise also as regards fallacies of Accident and each of the other types, some of the arguments will be easier to see while others are more difficult; also to grasp to which class a fallacy belongs, and whether it is a refutation or not a refutation, is not equally easy in all cases.

An incisive³ argument is one which produces the greatest perplexity: for this is the one with the sharpest fang⁴. Now perplexity is twofold, one which occurs in reasoned arguments, respecting which of the propositions asked one is to demolish⁵, and the other in contentious⁶ arguments, respecting the manner in which one is to assent⁷ to what is propounded⁸. Therefore it is in syllogistic⁹ arguments that the more incisive ones produce the keenest heart-searching. Now a syllogistic argument is most incisive if from premisses that are as generally accepted as possible it demolishes¹⁰ a conclusion that is accepted as generally as possible. For the one argument, if the contradictory¹¹ is changed about, makes all the resulting syllogisms alike in character: for always from premisses that are generally accepted it will prove a conclusion, negative or positive as the case may be, that is just as generally accepted; and therefore one is bound to feel perplexed¹². An argument, then, of this kind is the most incisive, viz. the one that puts its conclusion on all fours with the propositions asked; and second comes the one that argues from premisses, all of which are equally convincing: for this will produce an equal perplexity as to what kind of premiss, of those asked, one should demolish. Herein is a difficulty: for one must demolish something, but what one must demolish is uncertain. Of contentious arguments, on the other hand, the most incisive is the one which, in the first place, is characterized by an initial uncertainty¹³ whether it has been properly reasoned or not; and also whether the solution depends on a false premiss or on the drawing of a distinction; while, of the rest, the second place is held by that whose solution clearly depends upon a distinction or a demolition¹⁴, and yet it does not reveal clearly which it is of the premisses asked, whose demolition, or the drawing of a distinction within it, will bring the solution about, but even leaves it vague whether it is on the conclusion or on one of the premisses that the deception¹⁵ depends.

Now sometimes an argument which has not been properly reasoned is silly, supposing the assumptions required to be extremely contrary to the general view or false; but sometimes it ought not to be held in contempt. For whenever some question is left out, of the kind that concerns both the subject and the nerve of the argument, the reasoning that has both failed to secure this as well, and also failed to reason properly, is silly; but when what is omitted is some extraneous¹⁶ question, then it is by no means to be lightly despised, but the argument is quite respectable, though the questioner has not put his questions well.

Just as it is possible to bring a solution sometimes against the argument, at others against the questioner and his mode of questioning, and at others against neither of these, likewise also it is possible to marshal one’s questions and reasoning both against the thesis, and against the answerer and against the time, whenever the solution requires a longer time to examine than the period available.
