Practical Argumentation | Page 3

certain ideas are true, and also (2) to persuade them to act in accordance with the truth presented. Neither conviction nor persuasion can with safety be omitted. An appeal to the intellect alone may demonstrate principles that cannot be refuted; it may prove beyond a doubt that certain theories are logical and right, and ought to be accepted. But this sort of argument is likely to leave the person addressed cold and unmoved and unwilling to give up his former ideas and practices. A purely intellectual discourse upon the evils resulting from a high tariff would scarcely cause a life-long protectionist to change his politics. If, however, some emotion such as duty, public spirit, or patriotism were aroused, the desired action might result. Again it frequently happens that before the arguer can make any appeal to the logical faculties of those he wishes to influence, he will first have to use persuasion in order to gain their attention and to arouse their interest either in himself or in his subject. On the other hand, persuasion alone is undoubtedly of even less value than conviction alone. A purely persuasive argument can never be trusted to produce lasting effects. As soon as the emotions have cooled, if no reasonable conviction remains to guide future thought and action, the plea that at first seemed so powerful is likely to be forgotten. The preacher whose sermons are all persuasion may, for a time, have many converts, but it will take something besides emotional ecstasy to keep them "in good and regular standing."
The proportion of conviction and persuasion to be used in any argumentative effort depends entirely upon the attending circumstances. If the readers or hearers possess a high degree of intelligence and education, conviction should predominate; for it is a generally accepted fact that the higher man rises in the scale of civilization, the less he is moved by emotion. A lawyer's argument before a judge contains little except reasoning; before a jury persuasion plays an important part. In the next place, the arguer must consider the attitude of those whom he would move. If they are favorably disposed, he may devote most of his time to reasoning; if they are hostile, he must use more persuasion. Also the correct proportion varies to some extent according to the amount of action desired. In an intercollegiate debate where little or no action is expected to result, persuasion may almost be neglected; but the political speech or editorial that urges men to follow its instructions usually contains at least as much persuasion as conviction.
The aspirant for distinction in argumentation should study and acquire certain characteristics common to all good arguers. First of all, he should strive to gain the ability to analyze. No satisfactory discussion can ever take place until the contestants have picked the question to pieces and discovered just exactly what it means. The man who does not analyze his subject is likely to seize upon ideas that are merely connected with it, and fail to find just what is involved by the question as a whole. The man skillful in argumentation, however, considers each word of the proposition in the light of its definition, and only after much thought and study decides that he has found the real meaning of the question. But the work of analysis does not end here; every bit of proof connected with the case must be analyzed that its value and its relation to the matter in hand may be determined. Many an argument is filled with what its author thought was proof, but what, upon close inspection, turns out to be mere assertion or fallacious reasoning. This error is surpassed only by the fault of bringing in as proof that which has no direct bearing at all upon the question at issue. Furthermore, the arguer must analyze not only his own side of the discussion but also the work of his opponent, so that with a full knowledge of what is strong and what is weak he may make his attack to the best advantage. Next to the ability to analyze, the most important qualification for an arguer to possess is the faculty of clearly presenting his case. New ideas, new truths are seldom readily accepted, and it is never safe to assume that the hearer or the reader of an argument will laboriously work his way through a mass of obscure reasoning. Absolute clearness of expression is essential. The method of arriving at a conclusion should be so plain that no one can avoid seeing what is proved and how it is proved. Lincoln's great success as a debater was due largely to his clearness of presentation. In the third place, the person who would control his fellow men must assume qualities of leadership. Remembering that
