Full Idea
I might as well question the laws of logic as the laws of chess. If I change the rules it is a different game and there is an end of it.
Gist of Idea
Laws of logic are like laws of chess - if you change them, it's just a different game

A Reaction
No, that isn't the end of it, because there are meta-criteria for preferring one game to another. Why don't we just give up classical logic? It would be such fun to have a wild wacky logic. We can start with 'tonk'.
