This link was mentioned in the blog “Telic Thoughts” recently. I’ve seen many of these tactics in the past, here are some of my favorite entries:

10. If you opponent answers all your questions negatively and refuses to grant you any points, ask him or her to concede the opposite of your premises.

This may confuse the opponent as to which point you actually seek him to concede.

11. If the opponent grants you the truth of some of your premises, refrain from asking him or her to agree to your conclusion.

Later, introduce your conclusions as a settled and admitted fact.

Your opponent and others in attendance may come to believe that your conclusion was admitted.

14. Try to bluff your opponent.

If he or she has answered several of your question without the answers turning out in favor of your conclusion, advance your conclusion triumphantly, even if it does not follow.

If your opponent is shy or stupid, and you yourself possess a great deal of impudence and a good voice, the technique may succeed.

18. If your opponent has taken up a line of argument that will end in your defeat, you must not allow him to carry it to its conclusion.

Interrupt the dispute, break it off altogether, or lead the opponent to a different subject.

28. When the audience consists of individuals (or a person) who is not an expert on a subject, you make an invalid objection to your opponent who seems to be defeated in the eyes of the audience.

This strategy is particularly effective if your objection makes your opponent look ridiculous or if the audience laughs.

If your opponent must make a long, winded and complicated explanation to correct you, the audience will not be disposed to listen to him.

32. A quick way of getting rid of an opponent’s assertion, or of throwing suspicion on it, is by putting it into some odious category.

Example: You can say, “That is fascism” or “Atheism” or “Superstition.”

In making an objection of this kind you take for granted

1)That the assertion or question is identical with, or at least contained in, the category cited;


2)The system referred to has been entirely refuted by the current audience.

38 Become personal, insulting and rude as soon as you perceive that your opponent has the upper hand.

In becoming personal you leave the subject altogether, and turn your attack on the person by remarks of an offensive and spiteful character.
