Berkeley's Idealism

[Jackalope]

You claimed an observer, now provide it, don't wriggle, don't shift the burden of proof, don't change the subject.

All I am saying is that we share the burden of proof. You must prove the existence of a physical reality independent of a mind that observes it. I must prove the existence of a mind independent of physical reality. Since neither of us can do that both of our ontological claims are equally valid.

By that reasoning, my ontological claim to being the Great Old One Cthulhu is equally valid as well.
