We charge him with having broken his coronation oath; and we are told that he kept his marriage vow! We accuse him of having given up his people to merciless inflictions of the most hot-headed and hard-hearted of prelates; and the defence is, that he took his little son on his knee and kissed him! We censure him for having violated the articles of the Petition of Right, after having, for good and valuable consideration, promised to observe them; and we are informed that he was accustomed to hear prayers at six o'clock in the morning! It is to such considerations as these, together with his Vandyke dress, his handsome face, and his peaked beard, that he owes, we verily believe, most of his popularity with the present generation.
Appealing to Prejudice or Passions. The question is also ignored when the speaker appeals to the prejudices or passions of his audience (argumentum ad populum). Persons of some intellect resent this as almost an insult if they are in the audience, yet it is often resorted to by speakers who would rather produce the effect they desire by the use of any methods, right or wrong. Its use in court by unscrupulous lawyers to win decisions is checked by attempts on the part of judges to counteract it in their charges to the jury, but its influence may still persist. Mark Antony in Shakespere's play, Julius Caesar, used it in his oration over the dead body of Caesar to further his own ends.
Taking Advantage of Ignorance. Just as a speaker may take advantage of the prejudices and passions of an audience, so he may take advantage of their ignorance. Against the blankness of their brains he may hurl unfamiliar names to dazzle them, cite facts of all kinds to impress them, show a wide knowledge of all sorts of things, "play up to them" in every way, until they become so impressed that they are ready to accept as truth anything he chooses to tell them. Any daily paper will provide examples of the sad results of the power of this kind of fallacious reasoning. The get-rich-quick schemes, the worthless stock deals, the patent medicine quacks, the extravagantly worded claims of new religions and faddist movements, all testify to the power this form of seemingly convincing argument has over the great mass of the ignorant.
The Fallacy of Tradition. In discussing the burden of proof it was said that such burden rests upon the advocate of change, or novel introductions, etc. This tendency of the people at large to be rather conservative in practice links with the fallacy of tradition, the belief that whatever is, is right. In many cases such a faith is worse than wrong, it is pernicious. Many of the questions concerning relations of modern society—as capital and labor—are based upon this fallacy. Henry Clay was guilty of it when he announced, "Two hundred years of legislation have sanctioned and sanctified negro slaves as property." The successful way to dispose of such a fallacy is illustrated by William Ellery Channing's treatment of this statement.
But this property, we are told, is not to be questioned on account of its long duration. "Two hundred years of legislation have sanctioned and sanctified negro slaves as property." Nothing but respect for the speaker could repress criticism on this unhappy phraseology. We will trust it escaped him without thought. But to confine ourselves to the argument from duration; how obvious the reply! Is injustice changed into justice by the practice of the ages? Is my victim made a righteous prey because I have bowed him to the earth till he cannot rise? For more than two hundred years heretics were burned, and not by mobs, not by lynch law, but by the decrees of the councils, at the instigation of theologians, and with the sanction of the laws and religions of nations; and was this a reason for keeping up the fires, that they had burned two hundred years? In the Eastern world successive despots, not for two hundred years, but for twice two thousand have claimed the right of life and death over millions, and, with no law but their own will, have beheaded, bowstrung, starved, tortured unhappy men without number who have incurred their wrath; and does the lapse of so many centuries sanctify murder and ferocious power?
Attacking a Speaker's Character or Principles. Sometimes a speaker who finds himself unable to attack the truth of a proposition, or the arguments cited to support it, changes his tactics from the subject-matter to the opponent himself and delivers an attack upon his character, principles, or former beliefs and statements. This is called the argumentum ad hominem. In no sense is it really argument; it is irrelevant attack, and should be answered in a clear accurate demonstration of its unsuitability to the topic under consideration. It is unworthy, of course, but it is a tempting device for the speaker who can combine with it an appeal to the prejudices or passions of his audience.
The author has seen the entire population of Rome agitated because in a Senatorial debate one speaker attacked the family reputation of one of his opponents—a matter which, even if true, certainly had nothing to do with the bill under discussion. Political campaigns used to be disgraced by a prevalence of such appeals for votes. We may pride ourselves upon an advance in such matters, but there is still too much of it to let us congratulate ourselves upon our political good manners. You cannot ascribe bad faith to a man who argues now from a different attitude from the one he formerly supported. Changes of conviction are frequent in all matters. A man must be judged by the reasons he gives for his position at any one time. Many a person, who ten years ago would have argued against it, now believes a League of Nations possible and necessary. Many a person who a few years back could see no advantage in labor organizations is anxious now to join an affiliated union.
If you find the suggestion of such an attack in any of your own speeches, cast it out. If it is ever used against you, refute it by the strength of arguments you deliver in support of your position. Remove all assertions which do not relate to the debated topic. Make your audience sympathize with your repudiation of the remarks of your opponent, even though he has succeeded in delivering them.
Fallacies of Causal Relationship. The various fallacies that may be committed under the relation of cause and effect are many. Just because something happened prior to something else (the effect), the first may be mistakenly quoted as the cause. Or the reverse may be the error—the second may be assumed to be the effect of the first. The way to avoid this fallacy was suggested in the discussion of explanation by means of cause and effect where the statement was made that two events must not be merely sequential, they must be consequential. In argument the slightest gap in the apparent relationship is likely to result in poor reasoning, and the consequent fallacy may be embodied in the speech. When people argue to prove that superstitions have come true, do they present clear reasoning to show conclusively that the alleged cause—such as sitting thirteen at table—actually produced the effect of a death? Do they establish a close causal relationship, or do they merely assert that after a group of thirteen had sat at table some one did die? Mathematically, would the law of chance or probability not indicate that such a thing would happen a little less surely if the number had been twelve, a little more surely if fourteen?
