Actually, I’ve changed my mind. My new “standard refutation” of solipsism is to beat the solipsist to death with a baseball bat while telling them, “This is all in your head!”.
If the solipsist is right, I won’t be able to beat them to death with a baseball bat, because I don’t exist. If I’m right, the solipsist will never bother anyone ever again.
Unfair you say? Not logical you say? Then why didn’t you do a better job when you imagined I said it? You must have one piss-poor imagination if you can’t invent better illusions than me.
