Useful Logic Tricks

[RamistThomist]

Major Premise : Some dogs have spots.
Minor Premise : My dog has spots.
-----------------
My dog is some dog!

Major Premise: Sixty men can do a piece of work sixty times as quickly as one man.
Minor Premise: One man can dig a post hole in sixty seconds.
Conclusion: Sixty men can dig a post hole in one second!

This may be called the syllogism arithmetical, in which, by combining logic and arithmetics, we may gain a double certainty and be twiced blessed.





(this was a joke, btw).

Lewis Carroll - Symbolic Logic

Premise: Babies are illogical;
Premise: Illogical persons are despised.
Premise: No one is despised who can manage a crocodile.

Conclusion: Babies cannot manage crocodiles.

In Symbolic Logic, Carroll wrote a set of puzzles consisting of nonsense statements that had to be put in order and then a conclusion drawn.

Examples can be found here; I think there is some rewording here.

I knew the second blessing weren't logical!
