Logical Conundrum


I read somewhere that Bertrand Russell was impressed when an admirer knocked on his door and presented him with a scrap of paper with the words, "The statement on the other side of this paper is false", printed on one side of the paper and "The statement on the other side of this paper is true"

But if this statement is true then it can't be false now, can it?

Aha, the full story is here.
