Argumentum ad absurdum:
Or it is called: reducio ad absurdum.
Try the following logic on your friends, and enemies.
(Your friends may turn to enemies if they are subjected to your razor sharp reason.)
This is an argument that gets the blood flowing in the illogical and emotional when they can't stand your answers, or they have no refutation to what you deduce. Always remember, "The truth will make you odd."
Learn to take the heat when you are right !
The argument we are using is also can be called "reducio ad absurdum." - argument to absurity or to reduce to absurdity.
This argument shows that the doctrine or belief or principle of your opponent neccesarily leads to a contradiction or a ridiculous conclusion.
1. THE SILLY WORD "EXTREME" (as used by some who want to justify what cannot be justified):
They (opponents) use the word "extreme" as a weasle word to set you off balance and for you to let them hold their principle w/out complaint from you while permitting them not to take their belief to its logical conclusion.
Some people say, "Well abortion at 3 months is O.K., but at 6 months or 7 abortion is extreme".. They use the term extreme.. However, if abortion is OK at 3 months, it is logically OK at 6 or 7 months. It's the same being, same baby, not a different being.
If the logical application of the argument is not what the opponent wishes, then so be it.
He does want abortion at 3 months, but not at 6, so he thinks he can get away with his irrational belief by using the term "extreme" instead of recognizing the truth of the logical conclusion of his basic belief.
He can't have his cake and eat it too.
Your opponents may not like it at all when you say this.. So what? Truth is what it is.. Like it or not.
(Socrates had to drink the hemlock for the truth he told.)
2. Example 2 of "extreme" used in phoney way:
Some people will say to you "All morality is subjective".
Then you could logically hold a gun on them and say the following:
"I know it is.. Hand me your money and your car keys. I want a nice car, so I'm taking your Corvette."
The person says, "By subjective I didn't mean that extreme to which you are planning to go!"
You say, "Extreme? I am only being logical, for my subjective morality says for you to hand car and money over to me. Also my subjective morality says I can shoot you if you don't !"
Hopefully this will be enough either to " 1. Make the opponent furious.
2. Pound some sense into his thick head.
