I would say well, no the external world is itself Mention the world that we experience every day is that that just is what reality is like a color sounds Taste smells those are real features of the world, right? So that's what I would say and then I guess the second response Which is what I hinted at the in the opening statement, which is of course the problem of uh, I think it was yeah The problem with positive properties, right?
