The Art of Controversy
1. Carry your opponent’s proposition beyond its natural limits; exaggerate it.
The more general your opponent’s statement becomes, the more objections you can find against it.
The more restricted and narrow your own propositions remain, the easier they are to defend.
2 Use different meanings of your opponent’s words to refute his argument.
Example: Person A says, “You do not understand the mysteries of Kant’s philosophy.”
Person B replies, “Of, if it’s mysteries you’re talking about, I’ll have nothing to do with them.”
3 Ignore your opponent’s proposition, which was intended to refer to some particular thing.
Rather, understand it in some quite different sense, and then refute it.
Attack something different than what was asserted.
4 Hide your conclusion from your opponent until the end.
Mingle your premises here and there in your talk.
Get your opponent to agree to them in no definite order.
By this circuitous route you conceal your goal until you have reached all the admissions necessary to reach your goal.
5 Use your opponent’s beliefs against him.
If your opponent refuses to accept your premises, use his own premises to your advantage.
Example, if the opponent is a member of an organization or a religious sect to which you do not belong, you may employ the declared opinions of this group against the opponent.
6 Confuse the issue by changing your opponent’s words or what he or she seeks to prove.
Example: Call something by a different name: “good repute” instead of “honor,” “virtue” instead of “virginity,” “red-blooded” instead of “vertebrates”.
7 State your proposition and show the truth of it by asking the opponent many questions.
By asking many wide-reaching questions at once, you may hide what you want to get admitted.
Then you quickly propound the argument resulting from the proponent’s admissions.
