We must also assume those which are generally consequent and antecedent, for of general problems the syllogism also is from propositions, all or some of which are general, as the conclusion of each syllogism resembles its principles. Lastly, we are not to select things consequent to all, since there will not be composed a syllogism from them, on account of a reason which will appear from what follows.

Chapter 28

Those therefore who desire to confirm any thing of a certain universal, should look to the subject matter of what is confirmed, in respect of which it happens to be predicated; but of whatever ought to be predicated, of this, he should examine the consequents; for if one of these happens to be the same, one must necessarily be in the other. But if (it is to be proved) that a thing is not present universally but particularly, he must examine those which each follows, for if any of these is the same, to be particularly present is
