It depends on what you understand by "pantheism." Maybe that's the wrong term, if it implies a personal deity. I'm not saying that nature's alive, intelligent, or benevolent. On the contrary, I say that nature's creativity is monstrous because it's impersonal.

But I don't see any way to deny the logic that if everything's natural, and there's plainly much order in nature, natural forces, elements, systems, cycles, and so on are supremely creative (since they produced that order). It's trivially true since nature would have no rivals (apart from us, in a non-metaphysical sense, in that our artificial creations conflict with nature in the sense of the wilderness).
