Sorting out the Syllogisms
A syllogism is a three-part logical deduction. one of the simpler kinds of syllogisms called a categorical syllogism; runs as follows:
"All F's are G, x is an F; therefore, x is a G."
Major Premise: "ALL F's are G
Minor Premis: "x is an F"
Conclusion: "x is a G"
Think of an example of a categorical syllogism for each of the following:
1. The major premis is false, but the minor premise and conlcusion are both true.
Example: All (F) men are (G) selfish (FALSE), Mr. Horstman (X) is a man (True), Mr. Horstman is selfish (True)
2. The minor premise is false, but the major premise and conclusion are both true.
Example: All (F) lakes have (G) water (True), the (X) Pacific Ocean is a lake (FALSE), the Pacific Ocean has water. (True)
3. Both the major and minor premises are false, but the conclusion is true.
Example: All (F) reptiles are (G) mammals (False), A (X) Chicken is a reptile (FALSE), a chicken is a mammal (True).
"All F's are G, x is an F; therefore, x is a G."
Major Premise: "ALL F's are G
Minor Premis: "x is an F"
Conclusion: "x is a G"

Imagine that when you die, you will find yourself in a room with two doors, one leading to eternal paradise and teh other leading to eternal damnation. You can choose which door to walk through, but the trouble is that the doors are unmarked.
Each door has a guard, and you can ask each guard one "yes" or "no" question before you make your fateful choice. One of the two guards will always answer truthfully and the other other guard will always lie. Unfortunately, there's no way of knowing which guard is which.
What question should you ask on of the guards to ensure that you wind up in paradise?

Your task is to figure out which switch controls which light bulb. you can spend as much time as you like in the room with the light switches, but eventually you must go into the room with the light bulbs. Once you enter the room with the light bulbs, you can't return to the room with the light switches. What's more, after entering the room with the light bulbs, you have only thirty seconds to figure out which switch controls which bulb.
How do you do it?
