REBUTTAL SPEECHES. A rebuttal speech usually furnishes an excellent test of a debater's mastery of his subject. It shows whether or not he comprehends the fundamental principles that underly the argument. If he does not understand fundamentals, he cannot distinguish between what is worth answering and what is trivial. If he is not perfectly familiar with the arguments on both sides of the question, his refutation will be scattering; that is, he will rebut only a few of his opponent's headings, those for which, in his scanty preparation, he has discovered some answer. On the other hand, if he really understands the subject, he will deal largely with main ideas; and if his knowledge of the subject is as extensive as it should be, he will almost invariably be able to offer some opposition to every main heading used by the opposition.
When a debate is held between only two contestants, each one has to refute the whole argument of his opponent. In this case there are no complications; but when two teams are debating, the members of each must decide among themselves as to how the rebuttal shall be handled. One way is for each member to refute all he can, working independently of his colleagues. Much better results are secured, however, when a team works systematically. In the first place, a team should always resolve the opposing arguments into a hasty brief. The main points of the opposition can then be assigned for rebuttal to the various members of the team, and each debater can give thorough treatment to his assignment. In this way every point is sure to be covered, and there will be little, if any, duplication of work.
Such a course presupposes very careful preparation on the part of the debaters. It means that each member of the team must have sufficient knowledge and material at his command to oppose with credit any argument that may be advanced. In general, the assignment of headings for rebuttal may be such that each debater will refute those points of which he took an opposite view in his main speech, but as it is usually desirable to rebut arguments in the same order in which they were originally given, no member of the team can afford to shirk mastering each detail that in any way has a vital bearing upon the proposition.
THE LAST REBUTTAL SPEAKER. The work of the last speaker on each side differs somewhat from the work of his colleagues. All the speakers try to overthrow the opposing arguments, and by means of summaries keep their case as a whole before the audience. The last speaker devotes far less time to pure refutation, gives a more detailed summary, and, in addition, compares and contrasts the arguments of his side with the arguments of the opposition. This last process is called "amplifying and diminishing."
It is not always necessary to prove a main heading false in order to destroy its effectiveness. A debater may of necessity have to admit that the opposition has successfully established the points it set out to prove. In such a case, he cannot do better than to acknowledge the correctness of his opponent's proof, and then remembering that an audience awards a decision by a comparison of the relative weight of the proof of each side, amplify the importance of his own arguments, point by point, and diminish the importance of the arguments advanced by the other side.
For instance, in a debate on the question as to whether immigration should be restricted, the affirmative might maintain that unrestricted immigration brings serious political evils, and the negative might show that the policy of nonrestriction greatly increases the wealth of the country. If neither of these contentions be successfully refuted, the favor of the audience will incline towards the affirmative or the negative, as far as those two points are concerned, according as they think that political purity or economic prosperity is the more important. Plainly, it would be for the interest of the affirmative to convince the audience that the preservation of political integrity is of greater moment than any mere material gain.
In many respects the last rebuttal speeches on each side are the most conspicuous and decisive parts of a debate. If the last speech is hesitating and weak, it is liable to ruin all preceding efforts, even though they were of the highest order; if it is enthusiastic and strong, it will often cover up preceding defects, and turn defeat into victory. Because of its importance this portion of the work usually falls to the best debater on the team, and if he is wise he will give it his greatest thought and care. In this speech he should strive in every possible way to attain perfection. His delivery should be emphatic and pleasing; his ideas should be logically arranged; and his knowledge of what he has to say should be so complete that there will be no hesitation, no groping for words. Furthermore, he should introduce an element of persuasion; to reach both the minds and the hearts of his hearers is essential for the greatest success. All this has to be done in a short time, yet to be of a high rank even the shortest closing speeches must contain these characteristics.
SPECIAL FEATURES OF DEBATE.
An argument, like other kinds of composition, should possess the qualities of style known as Clearness, Force, and Elegance, and should in all respects observe the principles of Unity, Selection, Coherence, Proportion, Emphasis, and Variety. Since the student from his study of Rhetoric is already familiar with these matters, it would be superfluous to dwell upon them in this book. A good written argument, however, does not always make a good debate; limited time for speaking, lack of opportunity for the audience to grasp ideas and to reflect upon them, the presence of strong opposing arguments that must be met and overthrown with still stronger arguments,—these conditions render the heightening of certain characteristics indispensable in a debate.
Above all else the successful debater is forceful. He uses every possible device for driving home his arguments. He bends every effort toward making his ideas so plain and so emphatic that the audience will understand them and remember them. Realizing that the audience cannot, like the reader of a written article, peruse the argument a second time, he uses words and expressions that cause his thoughts to stick fast wherever they fall.
