Alice: Assume P Bob: P is False, there's no point Alice: It's just a starting point for my argument Bob: And what are you trying to go with your argument? Alice: A proof by contradiction Bob: A proof by contradiction assumes not(X), shows that it leads to a contradiction, therefore proving not(X) is false, and X is true. In this case assuming P to perform proof by contradiction means you will prove P is False. If that's all you want to do, there is no need as I am already in agreement that P is false. |

There's a difference between believing something is true and having a proof.
