Question Not so fast | Comment 2 of 46 |
Considering the statement, "Mohammad and I are both liars," the obvious line of logic is as follows:
  • If the statement is true, then Drew is a liar, which is a contradiction
  • Therefore Drew is a liar
  • If Drew is a liar and his statement is a lie, then Mohammad must not be a liar
But consider this line of reasoning: Instead of Mohammad, consider someone you know personally, in real life, who you know to be a liar. While thinking of that person, say "That person and I are both liars." Now, did your statement cause that person to suddenly not be a liar?
