middle is to have milk. Let A, be to be pregnant, B to have milk, C a woman. But that wise men are worthy, for Pittacus is a worthy man, is through the last figure, let A be worthy, B wise men, C Pittacus. It is true then A and B are predicated of C, except that they do not assert the one because they know it, but the other they assume. But that a woman is pregnant because she is pale, would be through the middle figure, for since paleness is a consequence of pregnancy, and also attends this woman, they fancy it proved that she is pregnant. Let A be paleness, to be pregnant B, a woman C. If then one proposition should be enunciated, there is only a sign, but if the other also be assumed, there is a syllogism, as for instance that Pittacus is liberal, for the ambitious are liberal, and Pittacus is ambitious, or again, that the wise are good, for Pittacus is good and also wise. Thus therefore syllogisms are produced, except indeed that the one in the first figure is incontrovertible if it be true, (for it is universal,) but that through the last is controvertible though the conclusion should be true, because the syllogism is not universal, nor to the purpose, for if Pittacus is worthy, it is not necessary that on this account other wise men also should be worthy. But that which is by the middle figure is always and altogether controvertible, for there is never a syllogism, when the terms thus subsist, for it is not necessary, if
