enunciations sentences, as that the diameter of a square is incommensurate with its side. Besides, of which there is a two-fold opinion as to truth, in these, by transferring the names, a person would especially escape detection, for from its being doubtful in what way the truth subsists, he will not appear sophistically to cavil, and from there, being opinions on both sides, he will not seem to answer falsely, for the transition will render his answer incapable of confutation by an elenchus.
Further, those interrogations which a person foresees, must be previously objected to and declared, for thus especially he will impede the inquirer.
Chapter 18
Since however a right solution is the detection of a false syllogism, (showing) by what interrogation the falsity occurs; but a syllogism is called false in two ways, (either if it is falsely concluded, or if not being a syllogism, it seems to be one,) what is now said to be a solution will be a correction of an apparent syllogism, (showing) from what interrogation it is apparent. Hence, it happens that those arguments which conclude by syllogism, are solved by negation, but apparent ones by distinction. Again, since some of the arguments syllogistically concluded are true, but others have a false conclusion; those which are false, according to the conclusion, we may solve in two ways, by taking away some one of the interrogations, and by showing that the conclusion does not thus subsist; but those (which are false), according to the propositions, by taking away some
