predicated as the third thing, then the oppositions are enunciated doubly; I say for instance, "a man is just;" here the word "is," I say, is placed as a third thing, whether noun or verb, in the affirmation, so that on this account, these will be four, of which two will subsist with respect to affirmation and negation, according to the order of consequence, as privations, but two will not. But I say that the word "is," will be added to "just" or to "not just," so that also negation is added, wherefore there will be four. We shall understand, however, what is said from the under-written examples: "A man is just," the negation of this is, "a man is not just;" "he is not a just man," the negative of this is, "he is not not a just man," for here the word "is," and "is not," will be added to the "just" and the "not just," wherefore these things, as we have shown in the Analytics, are thus arranged. The same thing will happen if the affirmation be of a noun taken universally, as for instance, "every man is just;" of this the negation is, "not every man is just," "every man is not just," "not every man is not just," except that it does not similarly happen that those which are diametrically opposed are co-verified; sometimes, however, this does hap-
