Logic Puzzle - Raymond Smullyan

This quote ble lagt til av user71700
There is a question I could ask you that has a definite correct answer - either yes or no - but it is logically impossible for you to give the correct answer. You might know what the correct answer is, but you cannot give it. Anybody other than you might possibly be able to give the correct answer, but you cannot! Can you figure out what question I could have in mind?

My favorite logic puzzle is one from Knot Theory. It was effectively solved by an impetuos young man named Alexander from Macedonia.

Self-reference is in a way, a proof of life. I think Godel said that.

Self-referential statements ruin logic. It's not interesting, though.

@Hunterz1200, you understood my answer?

bvw, on the other hand, perhaps people should answer, because most people don't scroll to the comments if they know they'll see what they don't want to see.

Can you not answer this question, please? Let folks think about it by themselves.
