Since minds have properties natural objects lack, how can minds be a part of nature?
This is a philosophical “problem” which is just an artifact of dualism. Once you’ve conceived of “mind” and “natural objects” as being separate domains, such questions seem to make sense. But in fact, you never actually find any such “natural objects” independent of mind — what you always find is mind participating in any and all perceptions, conceptions, experiences… so the notion of “natural objects” as something existing independently of mind is a disconnected abstraction with no meaning except as a logical toy for mind to play with when having mind games with itself. In short, the question arises from an illusion that mind is something separate from reality. It’s like asking where the boundary of mind is — you have to conceive of mind as separate from the rest of reality for such a question to make any sense, but in fact no such boundary can be located.
