If the first stroke was intended to provoke the adversary to strike, the second will lead to the third, while if the challenge be repeated it will lead to the fourth stroke, so that there will be two parries and two attacks. And tile process may be prolonged still further.
But refutation also includes that simple form of proof, which I described above, [*](v. xii. 12.) based on an appeal to the emotions and mere assertion; for an example see the words of Scaurus which I have already quoted. [*](v. xii. 10.) Nay, I am not sure that this form of proof is not actually of more frequent occurrence when something is denied.
