This book pretends but little to originality in material. Its aim is to offer the old in a form that shall meet the needs of young students who are beginning work in debate. The effort has been made only to present the elements of forensic work so freed from technicality that they may be apparent to the student with the greatest possible economy of time and the least possible interpretation by the teacher.
It is hoped that the book may serve not only those schools where debating is a part of the regular course, but also those institutions where it is a supplement to the work in English or is encouraged as a "super-curriculum" activity.
Although the general obligation to other writers is obvious, there is no specific indebtedness not elsewhere acknowledged, except to Mr. Arthur Edward Phillips, whose vital principle of "Reference to Experience" has, in a modified form, been made the test for evidence. It is my belief that the use of this principle, rather than the logical and technical forms of proof and evidence, will make the training of debate far more applicable in other forms of public speaking. My special thanks are due to Miss Charlotte Van Der Veen and Miss Elizabeth Barns, whose aid has added technical exactness to almost every page. I wish to thank also Miss Bella Hopper for suggestions in preparing the reference list of Appendix I. Most of all, I am indebted to the students whose interest has been a constant stimulus, and whose needs have been to me, as they are to all who teach, the one sure and constant guide.
L.S.L.
When we pause to look about us and to realize what things are really going on, we discern that everyone is talking and writing. Perhaps we wonder why this is the case. Nature is said to be economical. She would hardly have us make so much effort and use so much energy without some purpose, and some purpose beneficial to us. So we determine that the purpose of using language is to convey meaning, to give ideas that we have to someone else.
As we watch a little more closely, we see that in talking or writing we are not merely talking or writing something. We see that everyone, consciously or unconsciously, clearly or dimly, is always trying to do some definite thing. Let us see what the things are which we may be trying to do.
If you should tell your father, when you return from school, how Columbus discovered America on October 12, 1492, and should try to make him see the scene on shipboard when land was first sighted as clearly as you see it, you would be describing. That kind of discourse would be called description. Its purpose is to make another see in his mind's eye the same image or picture that we have in our own.
On the other hand, if you wished to tell him the story of the discovery of America, you would do something quite different. You would tell him not only of the first sight of land, but of the whole series of incidents which led up to that event. If he could follow you readily, could almost live through the various happenings that you related, you would be telling your story well. That kind of discourse is not description but narration.
Suppose, then, that your father should say: "Now tell me this: What is the difference between the discovery of America and the colonization of America?" You would now have a new task. You would not care to make him see any particular scene or live through the events of discovery but to make him understand something which you understand. You would show him that the discovery of America meant merely the fact that America was found to be here, but that colonization meant the coming, not of the explorers, but of the permanent settlers. This form of discourse which makes clear to someone else an idea that is already clear to us is called exposition.
And now suppose your father should say: "Well, you have told me a great deal which I may say is interesting enough, but it seems to me rather useless. What is the purpose of all this study? Why have you spent so much time learning of this one event?" You would of course answer: "Because the discovery of America was an event of great importance."
He might reply: "I still do not believe that." Then you would say: "I'll prove it to you," or, "I'll convince you of it." You would then have undertaken to do what you are now trying to learn how to do better—to argue. For argumentation is that form of discourse that we use when we attempt to make some one else believe as we wish him to believe. "Argumentation is the art of producing in the mind of someone else a belief in the ideas which the speaker or writer wishes the hearer or reader to accept."[1]
You made use of argumentation when you urged a friend to take the course in chemistry in your school by trying to make him believe it would be beneficial to him. You used argumentation when you urged a friend to join the football squad by trying to make him believe, as you believe, that the exercise would do him good. A minister uses argumentation when he tries to make his congregation believe, as he believes, that ten minutes spent in prayer each morning will make the day's work easier. The salesman uses argumentation to sell his goods. The chance of the merchant to recover a rebate on a bill of goods that he believes are defective depends entirely on his ability to make the seller believe the same thing. On argumentation the lawyer bases his hope of making the jury believe that his client is innocent of crime. All of us every day of our lives, in ordinary conversation, in our letters, and in more formal talks, are trying to make others believe as we wish them to believe. Our success in so doing depends upon our skill in the art of argumentation.
1. Out of your study or reading of the past week, give an illustration of: (1) narration; (2) description; (3) exposition; (4) argumentation.
2. During the past week, on what occasions have you personally made use of: (1) narration; (2) description; (3) exposition; (4) argumentation?
3. Explain carefully the distinction between description and exposition. In explaining this distinction, what form of discourse have you used?
4. Define argumentation.
5. Skill in argumentation is a valuable acquisition for:

Now, since we have decided upon a definition of argumentation, let us see what we mean by the term "debate" as it will be used in this work.
We have said that argumentation is the art of producing in the mind of someone a belief in something in which we wish him to believe.
Now it is obvious that this can be accomplished in different ways. Perhaps the most common method of attempting to bring someone to believe as we wish is the oral method. On your way to school you meet a friend and assert your belief that in the coming football game the home team will win. You continue: "Our team has already beaten teams that have defeated our opponent of next Saturday, and, moreover, our team is stronger than it has been at any time this season." When you finish, your friend replies: "I believe you are right. We shall win."
You have been carrying on oral argumentation.
If, when you had finished, your friend had not agreed with you, your effort would have been none the less argumentation, only it would have been unsuccessful. If you had written the same thing to your friend in a letter, your letter would have been argumentative.
Suppose your father were running for an office and should make a public speech. If he tried to make the audience believe that the best way to secure lower taxes, better water, and improved streets would be through his election, he would be making use of oral argumentation. If he should do the same thing through newspaper editorials, he would be using written argumentation.
Argumentation, then, may be carried on either in writing or orally, and may vary from the informality of an ordinary conversation or a letter to a careful address or thoughtful article.
What, then, is debate as we shall use the word in this work, and what is the relation of argumentation to debate? The term "debate" in its general use has, of course, many senses. You might say: "I had a debate with a friend about the coming football game." Or your father might say: "I heard the great Lincoln and Douglas debates before the Civil War." Although both of you would be using the term as it is generally used, you would not be using it as it will be used in this book, or as it is best that a student of argumentation and debate should use it.
The term "debate," in the sense in which students of these subjects should use it, means oral argumentation carried on by two opposing teams under certain prescribed regulations, and with the expectation of having a decision rendered by judges who are present. This is "debate" used, not generally, as you used it in saying, "I debated with a friend," but technically, as we use it when we refer to the Yale-Harvard debate or the Northern Debating League. In order to keep the meaning of this term clearly in mind, use it only when referring to such contests as these. In speaking of your argumentative conversation with your friend or of the forensic contests between Lincoln and Douglas, use the term "discussion" rather than "debate."
It is true that the controversy between Lincoln and Douglas conformed to our definition of "debate" in being oral; moreover, at least in sense, two teams (of one man each) competed, but there were no judges, and no direct decision was rendered.
Since argumentation, then, is the art of producing in the mind of someone else a belief in the idea or ideas you wish to convey, and debate is an argumentative contest carried on orally under certain conditions, it is clear that argumentation is the broader term of the two and that debate is merely a specialized kind of argumentation. Football is exercise, but there is exercise in many other forms. Debate is argumentation, but one can also find argumentation in many other forms.
The following diagram makes clear the work we have covered thus far. It shows the relation between argumentation and debate, and shows that the specialized term "debate" has the same relation to "discourse" that "football" has to "exercise."
1. Be prepared to explain orally in class, as though to someone who did not know, the difference between "argumentation" and "debate."
2. Set down three conditions that must exist before argumentation becomes debate.
3. Have you ever argued? Orally? In writing?
4. Have you ever debated? Did you win?
5. Which is the broader term, "argumentation," or "debate?" Why?
6. Compose some sentences, illustrating the use of the terms "debate" and "argumentation."
To debate successfully it is necessary to do three things:
Each of these three things is a distinct process, involving several steps. One is as important as another.
It is impossible to prove the issues until we have found them, but equally impossible to show the audience what the issues are until we have shown what the thing is which we wish those issues to support. First, then, let us see what we mean by making perfectly clear what you wish to have the audience believe.
Suppose that you should meet a friend who says to you: "I am going to argue with you about examinations." You might naturally reply: "What examinations?" If he should say, "All examinations: the honor system in all examinations," you might very reasonably still be puzzled and ask if by all examinations he meant examinations of every kind in grade school, high school, and college, as well as the civil service examinations, and what was meant by the honor system.
He would now probably explain to you carefully how several schools have been experimenting with the idea of giving all examinations without the presence of a teacher or monitor of any sort. During these examinations, however, it has been customary to ask the students themselves to report any cheating that they may observe. It is also required that each student state in writing, at the end of his paper, upon honor, that he has neither given nor received aid during the test. "To this method," your friend continues, "has been given the name of the honor system. And I believe that this system should be adopted in all examinations in the Greenburg High School."
He has now stated definitely what he wishes to make you believe, and he has done more; he has explained to you the meaning of the terms that you did not understand. These two things make perfectly clear to you what he wishes you to believe, and he has thus covered the first step in argumentation.
From this illustration, then, several rules can be drawn. In the first place your friend stated that he wished to argue about examinations. Why could he not begin his argument at once? Because he had not yet asked you to believe anything about examinations. He might have said, "I am going to explain examinations," and he could then have told you what examinations were. That would have been exposition. But he could not argue until he had made a definite assertion about the term "examination."
Rule one would then be: State in the form of a definite assertion the matter to be argued.
In order to be suitable for debating, an assertion or, as it is often called, proposition, of this kind should conform to certain conditions:
But you noticed that your friend had not only to state the question definitely, but to explain what the terms of the proposition meant. He had to tell you what the "honor system" was.
Our second rule, then, for making the question clear, is: In the proposition as stated, explain all terms that may not be entirely clear to your audience.
And in explaining or defining these terms, there are certain things that you must do. You must make the definition clear, or it will be no better than the term itself. This is not always easy. In defining "moral force" a gentleman said: "Why, moral force is er—er—moral force." He did not get very far on the way toward making his term clear. Be sure that your definition really explains the term.
Then one must be careful not to define in a circle. Let us take, for example, the assertion or proposition, "The development of labor unions has been beneficial to commerce." If you should attempt to define "development" by saying "development means growth," you would not have made the meaning of the term much clearer; and if in a further attempt to explain it, you could only add "And growth means development," you would be defining in a circle.
There is still another error to be avoided in making your terms clear to your audience. This error is called begging the question. This occurs when a term is defined in such a way that there is nothing left to be argued.
Suppose your friend should say to you: "I wish to make you believe that the honor system should be used in all examinations in the Greenburg High School." You ask him what he means by the "honor system." He replies: "I mean the best system in the world." Is there anything left to argue? Hardly, if his definition of the term honor system is correct, for it would be very irrational indeed to disagree with the assertion that the best system in the world should be adopted in the Greenburg High School.
To summarize: Define terms carefully; make the definition clear; do not define in a circle, and do not beg the question.
As you have already noticed, terms in argumentation, such as "honor system," often consist of more than one word. They sometimes contain several words. "A term [as that word is used in debating and argumentation] may consist of any number of names, substantive or objective, with the articles, prepositions, and conjunctions required to join them together; still it is only one term if it points out or makes us think of only one thing or object or class of objects."[2] In such cases a dictionary is of little use. Take the term "honor system," the meaning of which was not clear to you. A dictionary offers no help. How is the student who wishes to discuss this question to decide upon the meaning of the term? Notice how your friend made it clear to you. He gave a history of the question that he wished to argue. He showed how the term "honor system" came into use and what it means where that system of examinations is in vogue. This, then, is the only method of making sure of the meaning of a term: to study the history of the question and see what the term means in the light of that history. This method has the added advantage that a term defined in this way will not only be entirely clear to your audience, but will also tend to convince them.
A dispute may arise between yourself and an opponent as to the meaning of a term. He may be relying on a dictionary or the statement of a single writer, while you are familiar with the history of the question. Under those circumstances it will be easy for you to show the judges and the audience that, although he may be using the term correctly in a general way, he is quite wrong when the special question under discussion is considered.
To make this more clear, let us take a specific instance. Suppose that you are debating the proposition, "Football Should Be Abolished in This High School." Football, as defined in the dictionary, differs considerably from the game with which every American boy is familiar. Further, the dictionary defines both the English and the American game. If your opponent should take either of these definitions, he would not have much chance of convincing an American audience that it was correct. Or if he should define football according to the rules of the game as it was played five or ten years ago, he would be equally ineffective.
You, on the other hand, announce that in your discussion you will use the term "football" as that game is described in Spaulding's present year's rule book for the American game, and that every reference you make to plays allowed or forbidden will be on the basis of the latest ruling. You then have a definition based on the history of the question. As you can see, the case for or against English football would be different from that of the American game. In the same way the case for or against football as it was played ten years ago would be very different from the case of football as it is played today.
All this does not mean that definitions found in dictionaries or other works of reference are never good; it means simply that such definitions should not be taken as final until the question has been carefully reviewed. Try to think out for yourself the meaning of the question. Decide what it involves and how it has arisen, or could arise in real life. Then, when you do outside reading on the subject, keep this same idea in mind. Keep asking yourself: "How did this question arise? Why is it being discussed?" You will be surprised to find that when you are ready to answer that question you will have most of your reading done, for you will have read most of the arguments upon it. Then you are ready to make it clear to the audience.
When you have thus given a clear and convincing definition of all the terms, it is a good plan to restate the whole question in the light of those definitions.
For instance, notice the question of the "honor system." The original question might have been concisely stated: "All Examinations in the Greenburg High School Should Be Conducted under the Honor System."
After you have made clear what you mean by the "honor system," you will be ready to restate the question as follows: "The question then is this: No Teacher Shall Be Present during Any Examination in the Greenburg High School, and Every Student Shall Be Required to State on Honor That He Has Neither Given Nor Received Aid in the Examinations."
Your hearers will now see clearly what you wish them to believe.
Thus far, then, we have seen that to debate well we should have a question which is of interest to ourselves and to the audience. The first step toward success is to make clear to our hearers the proposition presented for their acceptance. This may be done:
When you have made perfectly clear to your hearers what you wish them to believe, the next step is to show them why they should believe it. The first step in this process, as we saw at the beginning of Lesson III, is to see what points, if proved, will make them believe it.
These points, as we call them, are better known as "issues." The issues are really questions, the basic questions on which your side and the other disagree. The negative would answer "No" to these issues, the affirmative would say "Yes."
The issues when stated in declarative sentences are the fundamental reasons why the affirmative believes its proposition should be believed.
A student might be arguing with himself whether he would study law or medicine. He would say to himself: "These are the issues: For which am I the better adapted? Which requires the more study? Which offers the better promise of reward? In which can I do the more good?"
Should he argue with a friend in order to induce him to give up law and to study medicine, he would use similar issues. He would feel that if he could settle these questions he could convince his friend. Now, however, he would state them as declarative sentences and say: "You are more adapted to the profession of medicine; you can do more good in this field," etc. If the friend should open the question, he would be in the position of a man on the negative side of a debate. He would state the issues negatively as his reasons. He would say: "I am not so well adapted to the study of medicine; it offers less promise of reward," etc.
Each of these would in turn depend upon other reasons, but every proposition will depend for its acceptance on the proof of a few main issues. Perhaps this point can be made clearer by an illustration. Suppose we should take hold of one small rod which we see in the framework of a large truss bridge and should say: "This bridge is strong because this rod is here." Our statement would be only partially true. The rod might be broken, and although the strength of the bridge as a whole might be slightly weakened, it would not fall. But suppose we should say: "This bridge really rests on these four great steel beams which run down to the stone abutment. If I can see that these four steel beams are secure, I can believe in the security of the bridge." So a mechanical engineer shows us that certain rods and bars of the framework hold up one beam, and how similar rods and bars sustain a second, and that yet other rods and bars distribute the weight that would press too heavily on a third, and so at last we are convinced that the bridge is safe. It is not because we have been shown that several of the bolts and braces are strong, but because we have been shown that the four great beams, upon which it rests, are reliable.
Thus it is with everything in which we believe. We do not believe that taxes are just because the government must have money to pay the president or to buy uniforms for the army officers. These things must be done, but they are incidentals. They are facts, but they are like the small braces of the bridge. We believe that taxation is just, because the government must have money for its work. Paying the president and buying uniforms are details of this more fundamental reason.
In the same way we might say: "Athletics should be encouraged in high schools because it will make John Brown, who will participate, more healthy." That is a reason, but again only a small supporting reason. We might rather choose a fundamental reason, which this slight reason would in turn support, and it would be: "Athletics should be encouraged in high schools because they improve the health of the students that participate."
In a recent debate between two large high schools on the proposition: "Resolved, That Contests within High Schools Should Be Substituted for Contests between High Schools," one of the contesting teams took the following as issues:
When these three facts had been demonstrated, there was little left to urge against the claim.
Recently among the universities of a certain section, this question was discussed: "Resolved, That the Federal Government Should Levy a Graduated Income Tax." (Such tax was conceded as constitutional.) One university decided upon these as the issues:
Here again if the debaters favoring a graduated income could show that the government does need the money, that the proposed tax is the best way to get it, and that such a tax would work in practice, they would make the audience believe their proposition. If the speakers on the negative side could show that the income of the federal government is sufficient, that, even if additional revenue is needed, this is a poor way to obtain it, or that this plan, though good in theory, is impracticable, they would have a good case. Thus in every question that is two-sided enough to be a good question for debate, there are certain fundamental issues upon which the disagreement between the affirmative and the negative can be shown to rest. When either side has answered "Yes" or "No" to these issues and has given reasons for its answer that will find acceptance in the minds of the audience and of the judges, it has won the debate. It is easy, then, to see why "determining the issues," and showing the audience what these issues are, is the second step in successful debating.
Although there is no fixed rule or touchstone by which an issue can immediately be determined, there are several rules which will aid in finding them.
With these general rules in mind, think the question over carefully. This process of determing the issues can, and should, go on at the same time as the process of learning what the question means. One helps the other. Having decided what will be the issues of the debate, set those issues down under appropriate heads; such as, "Is desirable," "Is needed," "Would work well," etc. Whenever you think of a reason why a thing is not needed, would not work, etc., put that down in a similar way. Now read more carefully (see "Reading References," Appendix I) on both sides of the question, and, whenever you find a reason for or against the proposition, set it down as above. The best method of doing this is to have a small pack of plain cards, perhaps two and one-half by four inches. Use one for each reason that you put down. As you think and read you will determine many reasons for the truth or falsity of the proposition. Gradually you will see that a great many of them are not so important as others and that they do not bear directly on the question, but in reality support some more important reason that you have set down. As you begin to notice this, go through your pack of cards and arrange them in the order of importance. Begin a new pile with every statement that seems to bear directly upon the proposition and put under it those statements that seem to support it. You will soon find that you have all your cards in two or three piles. Now examine the cards which you have on the top of each pile. See if the proof of these statements would convince any person that you are right. If so you have probably found the issues.
Always think first, then read, then think again.
If you have determined the issues wisely, it will be easy in the debate itself to show the audience and the judges what those issues are. You will have a tremendous advantage over your opponent, who in his haste or laziness may have chosen what are not the real issues of the question. He may present well the material that he has, but if that material does not support the fundamental issues of the question, you are right in calling the attention of the judges to that fact.
Few debates are won on the platform. They are won by thoughtful preparation. Be prepared.
Having determined what the issues are, and having shown the audience why the establishment of these issues should logically win belief in your proposition, all that remains is to prove the issues.
Now it is clear that neither the audience nor the judges can be led to agree with us and to accept our issues as proved, by our telling them that we should like to have them believe in the soundness of our views. Neither can we succeed in convincing them by telling them that they ought to believe as we wish. The modern audience is not to be cajoled or browbeaten into belief. How, then, are we to persuade our hearers to accept our assertions as true? The only method is to give them what they demand—reasons. We must tell why every statement is true. This process of telling why the issues are true so effectively that the audience and judges believe them to be true is called the proof.
Naturally, the reasons that we give in support of the issues will be no better than the issues themselves, unless we know what reasons the audience will believe. And how are we to know what reasons the audience will believe? We can best answer that question by determining why we ourselves believe those things which we accept. Why do we believe anything? We believe that water is wet; the sky, blue; fire, hot; and sugar, sweet, because in our experience we have always found them so. These things we believe because we have experienced them ourselves. There are other things that we believe in a similar way. We believe that not every newspaper report is reliable. We believe that a statement in the Outlook, the Review of Reviews, or the World's Work is likely to be more trustworthy than a yellow headline in the Morning Bugle. Our own experience, plus what we have heard of the experience of others, has led us to this belief. But there are still other things that we believe although we have not experienced them at all. We believe that Columbus visited America in 1492, that Grant was a great general, that Washington was our first president. Directly, these things have never been experienced by us, but indirectly they have. Others, within whose experience these things have fallen, have led us to accept them so thoroughly that they have become our experience second hand.
If we are told that a man who was in the Iroquois Theater fire was seriously burned, it seems reasonable to us because our experience recognizes burning as the result of such a situation. But if we are told that a man who fell into the water emerged dry, or that a general who served under Washington was born in 1830, we discredit it because such statements are not in accord with our experience. We are ready, then, to answer our question: "What reasons will those in the audience believe?" They will believe those statements which harmonize with their own experience, and will discredit those which are at variance with their experience. This experience, as we have seen, may be first hand, or direct; or it may be indirect, or second hand.
In every case, the speaker's argument must base every issue upon reasons that rest on what the hearers believe because of their own direct or indirect experience. Suppose I assert: "John Quinn was a dangerous man." Someone says: "Prove that statement." I answer: "He was a thief." Someone says: "If that is true, he was a bad man, but can you prove him a thief?" Then I produce a copy of a court record which states that, on a certain day, a duly constituted court found John Quinn guilty of robbing a bank. All my hearers now admit, not only that he was a thief, but also that he was a dangerous person. I have given them a reason for my statement, and a reason for that reason, until at last I have shown them that my assertion, that John Quinn is a dangerous citizen, rests on what they themselves believe—that a court record is reliable.
Sometimes an issue cannot be supported by a reason that will come at once within the experience of the audience. It is then necessary to support the first by a second reason that does come within its experience. Remember, then, as the fundamental rule, that the judges and audience will believe the issues of the proposition, and, as a result, the proposition itself, only when we show them, by the standard of their own experience, that we are right.
The reasons that we give in support of the issues are, in debating, called evidence. Evidence is not proof; evidence is the material out of which proof is made. Evidence is like the separate stones of a solid wall: no one alone makes the wall; each one helps make it strong. Evidence is like the small rods and braces of the truss bridge: no one alone supports the weight; each helps to sustain the great beams that are the real support of the bridge.
Suppose we had the proposition: "The Honor System of Examinations Should Be Established in the Greenburg High School." We assert: "There is but one issue: Will the students be honest in the examination?" Now, what evidence shall we use to show that they will be honest? We may turn to the experience of other schools. After a careful investigation we find evidence with which we may support the assertion in the following way:
The Honor System should be established in the Greenburg High School, for:
Here the statements used in support of the issue are evidence. If the evidence is strong enough to bring conviction to the audience to which you are speaking, it is proof.
But notice here an important point. Why should this tend to make those in the audience believe that the honor system should be adopted? Simply because we have shown them that it has worked well elsewhere, and their own experience tells them that what has been a benefit in other schools similar to this will be a benefit here.
And in its final analysis this evidence is no stronger than the words of the men who state that it has worked in schools (X) and (Y).
If the experience of the audience is that these men are untruthful or likely to exaggerate, our evidence will not be good evidence. If the experience of the audience is that these men are capable, honest, and reliable, this evidence will go far toward gaining acceptance of, and belief in, our proposition.
Many attempts have been made to put evidence into different classes and to give tests of good evidence. There is but one rule that the debater needs to use: In judging evidence for a debate consider what the effect will be on the audience and the judges. Will it be convincing to them? In other words, will it make their own experience quickly and strongly support the issues?
Time is always limited in a debate. The wise debater will then choose that evidence which will most quickly make his hearers feel that their own experience proves him right. When the speaker has done this, he has chosen the best evidence and has used enough of it.
In courts of law where witnesses appear in every case and testify as to circumstances that did or did not occur, it is necessary that the jury be able to distinguish carefully between what it should and should not believe. Witnesses often have a keen personal interest in the verdict and, therefore, are inclined to tell less or more than the truth. Sometimes witnesses are relatives of persons who would suffer if the case were decided against them and they have a tendency to give unfair testimony.
In order that the jury may decide as fairly as possible what evidence is sound and what is not, the attorneys on each side of the case make out a copy of what are called instructions. These are given to the judge who, provided he approves of them, reads them to the jury. Usually these instructions urge the jurors to consider four things. They must consider, first, whether or not the statements of the witness are probable; that is, are they consistent with human experience? Do they seem reasonable and natural? A second thing which the jury is told to bear in mind is the opportunity which the witness had of observing the facts of which he speaks. Was he in a position to be familiar with the thing he describes? In this connection, the jury is sometimes instructed to consider the physical and mental qualities of the witness. Is he a man who is physically and mentally able to judge what he observes under such circumstances? A third factor which the jury must consider is the possibility of prejudice on the part of the witness. Has he any reason to feel more favorably toward one side than toward the other? Is the defendant his friend or relative or employer? A final consideration is what is commonly called "interest in the case." It is clear that if the witness will be benefited by a certain verdict, he may be inclined to frame his evidence in such a way that it will tend toward that verdict. All these considerations are based on the rule of referring to experience. What a judge really says in a charge to the jury is this: "Does your experience warn you that the testimony of some of these witnesses is unsound? Determine upon that basis in what respects these witnesses have told the whole truth and in what respects they have not."
To summarize: The issues of a proposition are proved by being supported with evidence. Since evidence is the material with which we build the connection between the issues and the experience of the audience, that evidence will be best which will receive the quickest and strongest support from the experience of the hearers.[3]
