Sample text

H e took the first to be true because he used being instead of substance, since what is other t h a n substance is not substance. Because he takes it i n this way he tries to infer that being is one, but the second does not keep being restricted to substance, since it is not true that what is other t h a n substance is nothing. However, t a k i n g the first premiss as what is other t h a n a l l being is a l l * not being, one posits i n addition the second, that not being is nothing; the conclusion w h i c h follows from these premisses t a k e n this way is that what is other t h a n a l l being is a l l * nothing, a n d because of this conclusion it is agreed that there is more t h a n one being since the word 'all' indicates more t h a n one.

Or perhaps he says that it is false that A is predicated of C as equivalent to T o say i n this case that syllogistically A is predicated of C is false'. F o r even i f i t is true i n some other sense, it is false i n terms of being i n a syllogism; for he is not now speaking i n a precise way about the conclusion but is only indicating to us the difference between a n indeterminate and a u n i v e r s a l premiss by t a k i n g it that, although the proposition saying that cultured M i k k a l o s w i l l perish tomorrow is true, the proposition saying that every cultured M i k k a l o s w i l l perish tomorrow is not always true; for the words 'It is not 39 35 352,1 5 10 15 20 Translation universally true that cultured M i k k a l o s w i l l perish tomorrow' mean I t is not true that every cultured M i k k a l o s w i l l perish tomorrow'.

B u t i n the case of the t h i r d figure it is done away w i t h because it is agreed t h a t the conclusion of contingent premisses is contingent. H e recommends that i n setting out the terms i n the analysis of syllogisms of this k i n d we always set out the things corresponding to the states and not the states themselves. It should be pointed out that sometimes a mistake occurs because the middle has not been t a k e n to be the same i n both premisses or because it has been taken to be the same i n name only, for example, if it is assumed that colour of a l l white a n d white of every swan, since colour is not of every swan because a s w a n is not a colour.
