So that they who desire to solve an argument, should first consider if it is conclusive or inconclusive; next, whether the conclusion is true or false, that we may solve it either by division or subversion, and subverting it either in this or that way, as was observed before. Still, it makes a great difference whether a person, being interrogated or not, solves the argument, since to foresee is difficult, but to consider at leisure is easy.
Chapter 19
