Of course there's no aesthetic "experience" without a person to experience it. But that doesn't mean the experienced qualities are subjective.

What's objective is creative (and destructive) causality. And where there's creativity, there are aesthetic considerations.

I agree that at some level of analysis we're natural beings. But at another level, we're not: we're autonomous agents and we live in artificial, intelligently-designed refuges away from the wilderness. That's as unnatural as you can get within a natural universe.

Mind you, I'm only exploring these pantheistic and aesthetic ideas. I don't have full confidence in them, but I suspect they may be needed in an elevated secular society.
