But the great mistake of the whole doctrine creeps out at every page as we go on, and disproves the idea on which the De Oratore is founded. All Cicero's treatises on the subject, and Quintilian's, and those of the pseudo-Tacitus, and of the first Greek from which they have come, fall to the ground as soon as we are told that it must be the purport of the orator to turn the mind of those who hear him either to the right or to the left, in accordance with the drift of the cause.[253] The mind rejects the idea that it can be the part of a perfect man to make another believe that which he believes to be false. If it be necessary that an orator should do so, then must the orator be imperfect. We have the same lesson taught throughout. It is the great gift of the orator, says Antony, to turn the judge's mind so that he shall hate or love, shall fear or hope, shall rejoice or grieve, or desire to pity or desire to punish.[254] No doubt it is a great power. All that is said as to eloquence is true. It may be necessary that to obtain the use of it you shall educate yourself with more precision than for any other purpose. But there will be the danger that they who have fitted the dagger to the hand will use it. It cannot be right to make another man believe that which you think to be false. In the use of raillery in eloquence the Roman seems to have been very backward; so much so that it is only by the examples given of it by themselves as examples that we learn that it existed. They can appall us by the cruelty which they denounce. They can melt us by their appeals to our pity. They can terrify; they can horrify; they can fill us with fear or hope, with anger, with despair, or with rage; but they cannot cause us to laugh. Their attempts at a joke amuse us because we recognize the attempt. Here Caesar is put forward to give us the benefit of his wit. We are lost in surprise when we find how miserable are his jokes, and take a pride in finding that in one line we are the masters of the Romans. I will give an instance, and I pick it out as the best among those selected by Cicero. Nasica goes to call upon Ennius, and is informed by the maid-servant that her master is not at home. Ennius returns the visit, and Nasica halloos out from the window that he is not within. "Not within!" says Ennius; "don't I know your voice?" Upon which Nasica replies, "You are an impudent fellow! I had the grace to believe your maid, and now you will not believe me myself."[255] How this got into a law-case we do not know; it is told, however, just as I have told it. But there are enough of them here to make a small Joe Miller; and yet, in the midst of language that is almost divine in its expressions, they are given as having been worthy of all attention.
