Me, I would never have said that. "
Trumpsters" seem very sensitive people. Although... perhaps not so much when it comes to spelling.
Just as it goes without saying that this bollocks about only knowing experience assumes Cartesian dualism.
Bollocks.
That we only know our subjective experience doesn't imply that there isn't something we don't know. And what this something could be is anybody's guess, and why not a physical world.
If you don't take the religious position that there is more than one substance then existence of mental events is evidence of the physical events that instantiate them.
No, it's not like that. All we can say is that we have the impression that our perceptions
are a physical world. And we usually take this impression at face value. That would be called, I believe, "
naive realism". That's just... naive. It's also an impression we can't shake however hard we try. That in itself is interesting but it's no evidence of anything. It's merely the suggestion of something.
And, obviously, just admitting to yourself that you don't actually know that there is a physical world could not possibly entail anything as to the existence or otherwise of a physical world and, therefore, could not possibly entail Dualism.
