Question:

Can you explain the following sentence?

"This sentence is a lie."

True or false, and why?


Best Answer - Chosen by Asker: If "this sentence is a lie" is TRUE, then the sentence IS a lie. Since the sentence is a lie, it is wrong, so the sentence IS NOT a lie. This is impossible, it contradicts itself, so the statement cannot be true.

If "this sentence is a lie" is FALSE, then the sentence IS NOT a lie, making "this sentence is a lie" true. If it is true than the sentence IS a lie. So it contradicts itself once again.

The sentence is neither true or false, either way it contradicts itself.
