Name-calling is an example of this. Some speakers simply avoid facts that have direct bearing on the subject. On the other hand, he may bring in things that have no bearing on the issue. The reader may have seen speakers especially preachers repeat a thing over and over to try to win his point. But repetition is not proof of truth.
Sheer noise is used by some.
Personal attacks rather than attacks on what the other has to say, is still another device. Agreeing with another s conclusion while denying the base of that conclusion, even though it necessarily flows from the premise put forth by the other, is a fallacy. Playing on the imagination and feeling of the listeners by appealing to what may be popular is fallacious. Or, he may knock down an argument that the other has not put forth. We ve seen speakers in debates take advantage of the fact that an audience, or most in the audience, may not have enough knowledge to see that one speaker may be taking advantage of the other, because of the lack of knowledge on the part of the audience on that subject.
