seems' so: for in that way one avoids the impression of being either



refuted or paradoxical。 Since it is clear what is meant by 'begging



the original question'; and people think that they must at all costs



overthrow the premisses that lie near the conclusion; and plead in



excuse for refusing to grant him some of them that he is begging the



original question; so whenever any one claims from us a point such



as is bound to follow as a consequence from our thesis; but is false



or paradoxical; we must plead the same: for the necessary consequences



are generally held to be a part of the thesis itself。 Moreover;



whenever the universal has been secured not under a definite name; but



by a comparison of instances; one should say that the questioner



assumes it not in the sense in which it was granted nor in which he



proposed it in the premiss: for this too is a point upon which a



refutation often depends。



  If one is debarred from these defences one must pass to the argument



that the conclusion has not been properly shown; approaching it in the



light of the aforesaid distinction between the different kinds of



fallacy。



  In the case; then; of names that are used literally one is bound



to answer either simply or by drawing a distinction: the tacit



understandings implied in our statements; e。g。 in answer to



questions that are not put clearly but elliptically…it is upon this



that the consequent refutation depends。 For example; 'Is what



belongs to Athenians the property of Athenians?' Yes。 'And so it is



likewise in other cases。 But observe; man belongs to the animal



kingdom; doesn't he?' Yes。 'Then man is the property of the animal



kingdom。' But this is a fallacy: for we say that man 'belongs to'



the animal kingdom because he is an animal; just as we say that



Lysander 'belongs to' the Spartans; because he is a Spartan。 It is



evident; then; that where the premiss put forward is not clear; one



must not grant it simply。



  Whenever of two things it is generally thought that if the one is



true the other is true of necessity; whereas; if the other is true;



the first is not true of necessity; one should; if asked which of them



is true; grant the smaller one: for the larger the number of



premisses; the harder it is to draw a conclusion from them。 If; again;



the sophist tries to secure that has a contrary while B has not;



suppose what he says is true; you should say that each has a contrary;



only for the one there is no established name。



  Since; again; in regard to some of the views they express; most



people would say that any one who did not admit them was telling a



falsehood; while they would not say this in regard to some; e。g。 to



any matters whereon opinion is divided (for most people have no



distinct view whether the soul of animals is destructible or



immortal); accordingly (1) it is uncertain in which of two senses



the premiss proposed is usually meant…whether as maxims are (for



people call by the name of 'maxims' both true opinions and general



assertions) or like the doctrine 'the diagonal of a square is



incommensurate with its side': and moreover (2) whenever opinions



are divided as to the truth; we then have subjects of which it is very



easy to change the terminology undetected。 For because of the



uncertainty in which of the two senses the premiss contains the truth;



one will not be thought to be playing any trick; while because of



the division of opinion; one will not be thought to be telling a



falsehood。 Change the terminology therefore; for the change will



make the position irrefutable。



  Moreover; whenever one foresees any question coming; one should



put in one's objection and have one's say beforehand: for by doing



so one is likely to embarrass the questioner most effectually。







                                18







  Inasmuch as a proper solution is an exposure of false reasoning;



showing on what kind of question the falsity depends; and whereas



'false reasoning' has a double meaning…for it is used either if a



false conclusion has been proved; or if there is only an apparent



proof and no real one…there must be both the kind of solution just



described;' and also the correction of a merely apparent proof; so



as to show upon which of the questions the appearance depends。 Thus it



comes about that one solves arguments that are properly reasoned by



demolishing them; whereas one solves merely apparent arguments by



drawing distinctions。 Again; inasmuch as of arguments that are



properly reasoned some have a true and others a false conclusion;



those that are false in respect of their conclusion it is possible



to solve in two ways; for it is possible both by demolishing one of



the premisses asked; and by showing that the conclusion is not the



real state of the case: those; on the other hand; that are false in



respect of the premisses can be solved only by a demolition of one



of them; for the conclusion is true。 So that those who wish to solve



an argument should in the first place look and see if it is properly



reasoned; or is unreasoned; and next; whether the conclusion be true



or false; in order that we may effect the solution either by drawing



some distinction or by demolishing something; and demolishing it



either in this way or in that; as was laid down before。 There is a



very great deal of difference between solving an argument when being



subjected to questions and when not: for to foresee traps is



difficult; whereas to see them at one's leisure is easier。







                                19







  Of the refutations; then; that depend upon ambiguity and amphiboly



some contain some question with more than one meaning; while others



contain a conclusion bearing a number of senses: e。g。 in the proof



that 'speaking of the silent' is possible; the conclusion has a double



meaning; while in the proof that 'he who knows does not understand



what he knows' one of the questions contains an amphiboly。 Also the



double…edged saying is true in one context but not in another: it



means something that is and something that is not。



  Whenever; then; the many senses lie in the conclusion no



refutation takes place unless the sophist secures as well the



contradiction of the conclusion he means to prove; e。g。 in the proof



that 'seeing of the blind' is possible: for without the



contradiction there was no refutation。 Whenever; on the other hand;



the many senses lie in the questions; there is no necessity to begin



by denying the double…edged premiss: for this was not the goal of



the argument but only its support。 At the start; then; one should



reply with regard to an ambiguity; whether of a term or of a phrase;



in this manner; that 'in one sense it is so; and in another not so';



as e。g。 that 'speaking of the silent' is in one sense possible but



in another not possible: also that in one sense 'one should do what



must needs be done'; but not in another: for 'what must needs be'



bears a number of senses。 If; however; the ambiguity escapes one;



one should correct it at the end by making an addition to the



question: 'Is speaking of the silent possible?' 'No; but to speak of



while he is silent is possible。' Also; in cases which contain the



ambiguity in their premisses; one should reply in like manner: 'Do



people…then not understand what they know? 〃Yes; but not those who



know it in the manner described': for it is not the same thing to



say that 'those who know cannot understand what they know'; and to say



that 'those who know something in this particular manner cannot do



so'。 In general; too; even though he draws his conclusion in a quite



unambiguous manner; one should contend that what he has negated is not



the fact which one has asserted but only its name; and that



therefore there is no refutation。







                                20







  It is evident also how one should solve those refutations that



depend upon the division and combination of words: for if the



expression means something different when divided and when combined;



as soon as one's opponent draws his conclusion one should take the



expression in the contrary way。 All such expressions as the



following depend upon the combination or division of the words: 'Was X



being beaten with that with which you saw him being beaten?' and



'Did you see him being beaten with that with which he was being



beaten?' This fallacy has also in it an element of amphiboly in the



questions; but it really depends upon combination。 For the meaning



that depends upon the division of the words is not really a double



meaning (for the expression when divided is not the same); unless also



the word that is pronounced; according to its breathing; as eros and



eros is a case of
