@HoraceGreenley Ah yes, the epistemological question, how can we truly know anything? Maybe the true reality is that a malevolent demon is creating an artificial reality just for Horace to experience, and nothing else exists.
@HoraceGreenley I'll use Samuel Johnson's proof - drop a heavy rock on your toe, and then tell me that you have no way to verify if it hurts or not. This is evidence from personal experience. Claiming that God exists is not the same thing, unless you personally met him or something.
