65. Voice and Position. The matter of delivery is highly important, and here no man can trust to the light of nature. Any voice can be made to carry further and to be more expressive, and the poorest and thinnest voice can be improved. Every student who has a dream of being a public speaker should take lessons in elocution or in singing or in both. The expressiveness as well as the carrying power and the endurance of a voice depend on a knowledge of how to use the muscles of the chest, throat, and face; and trainers of the voice have worked out methods for the proper use of all these sets of muscles. A man who throws his breath from the top of his chest and does not use the great bellows that reach down to his diaphragm can get little carrying power. So with the throat: if it is stiff and pinched the tones will be high and forced, and listening to them will tire the audience nearly as much as making them will tire the speaker. Finally, the expressiveness of a voice, the thrill that unconsciously but powerfully stirs hearers, is largely a matter of the resonance that comes from the spaces above the mouth and behind the nose. A humorous singing teacher once declared that the soul resides in the bridge of the nose; and the saying is not so paradoxical as it sounds. Lessons in the use of all these parts, and faithful practice in the exercises which go with them, are essential for any man who wishes to make a mark in public speaking.
With the use of the voice, though less essential, goes the position and bearing on the platform. It is not necessary to insist that the more natural this is, the better. If you can wholly forget yourself and think only of your points, the chances are that your attitudes and position will take care of themselves. Only, before thus forgetting yourself, form the habit of talking without putting your hands in your pockets. You ought to need your hands to talk with, if not as much as a Frenchman or an Italian, yet enough to emphasize your points naturally. The mere physical stimulus to the eye of an audience in following your movements will help to keep their attention awake. Every one who has tried lecturing to a large class knows how much easier it is to hold them if he stands up and moves a little from time to time. Learn to stand easily and naturally, with your chest well expanded, and your weight comfortably balanced on your feet. If it comes natural to you, move about the stage slightly from time to time; but be careful not to look each time you move as if a string had been pulled. In attitude and gesture the only profitable council is, Be natural.
For all these matters of preparation, both of what you are going to say, the use of your voice, and your attitude and action on the platform, be prepared for hard practice with competent criticism. It is a good plan to practice talking from your outlines with your watch open, until you can bring your speech to an end in exactly the time allowed you. The gain in confidence when you go to the debate will in itself be worth the time. Again, practice speaking before a glass to make sure that you have no tricks of scowling or of making faces when you talk, and to get used to standing up straight and holding yourself well. What you see for yourself of your own ways will help you more than the advice of a critic.
But in all your preparation think beyond the special debate you are preparing for. What you are or should be aiming at is habit—the instinctive, spontaneous execution of rules which you have forgotten. When the habit is established you can let all these questions of voice, of attitude, of gesture, drop from your mind, and give your whole attention to the ideas you are developing, and the language in which you shall clothe them. Then the tones of your voice will respond to the earnestness of your feeling, and your gestures will be the spontaneous response to the emphasis of your thought. You will not be a perfect debater until all these matters are regulated from the unconscious depths of your mind.
In your attitude towards the debaters on the other side be scrupulously fair and friendly. In class debates the matter is finished when the debate is over; and what you are after is skill, and not beating some one. In interscholastic and intercollegiate debates victory is the end; but even there, after the debate you will often go out to supper with your opponents. Therefore demolish their arguments, but do not smash their makers.
If the first speech falls to you, set forth the facts in such a way that not only your opponents will have no corrections or protests to make, but that they will be wholly willing to make a start from your foundation. Yield all trivial points: it is a waste of your time and proof of an undeveloped sense of proportion to haggle over points that in the end nobody cares about. You have won a point if you can make the audience and the judges feel that you are anxious to allow everything possible to the other side.
If your opponent trips on some small point of fact or reasoning, don't heckle him; let it pass, or, at the most, point it out with some kindly touch of humor. If his facts or his reasoning are wrong on important points, that is your opportunity, and you must make the most of it. Even then, however, stick to the argument, and keep away from any appearance of being personal.
66. The Morals of Debating. There is a moral or ethical side to practice in debating which one cannot ignore. It is dangerous to get into the habit of arguing lightly for things in which one does not believe; and students may be forced into doing this if great care is not taken in the choice of subjects and sides. The remedy lies in using, so far as they can be kept interesting, questions in which there is no moral element; but still better in assigning sides to correspond with the actual views and preferences of the debaters. Where a question of principle is involved no one should ever argue against his beliefs. The better class of lawyers are scrupulous about this: they will not accept a brief which they believe to be in a cause which ought not to win. If you have clearly made up your mind on a question of public policy, you are in a false position if you argue, even for practice, against what you believe to be the right.
The formal debates of school and college are of necessity barren of practical result; yet even here your discussions have a potent effect in molding your opinions. It is a habit of mankind to start idly talking on a subject, and as idly taking sides; then, when the talk grows warmer, in the natural desire to carry a point to talk themselves into belief. This is a human, though not a very reasonable way of framing your views on public questions; and it does not make either for consistency or for usefulness as a voter. It is not good to back one's self into opinions of what makes for the common weal.
Furthermore, debate is something very different from dispute: to talk round and round a subject, contradicting blindly and asserting without bringing forward facts, has its place in our life with our friends, so long as it is good-natured; but it does not bring illumination. The essence of debate, whether in a classroom, in a city council, or in Congress, should be to throw light into dark corners, and to disentangle the view that most makes for the general good. For us in America noblesse oblige applies to every educated man. The graduate of a high school, and, even more, the graduate of a college, has taken exceptional benefits from the community. This obligation he can in part repay by helping all citizens to a better understanding of the issues on which the progress of the nation turns.
