Liar or not? (Posted on 2002-11-12) Difficulty: 3 of 5
A man walks up to you and says:
"Everything I say to you is a lie."

Is he telling you the truth or is he lying?

let's say he is lying.
so the statement "everything i(ie he) say to you is a lie" is a lie.the opposite of this must me the truth.consider the most general opposite of this statement.it is "not everything i say to you is a lie". this allows the possibility that this particular statement is a lie and solves the paradox {this type of paradox is known as loop hole paradox. a much tougher one is"i am lying"}
