From what I can tell about scientific naturalism from Paul Harrison's site, I would have to say that I do not have the emotional constitution to be a scientific pantheist. Just because something is natural doesn't mean it's good. Since you have given some thought to nature and what is natural, I wonder if you could help me get my mind out of this hamster wheel. Beaver's are natural. Dams which beavers build are natural.
Man is natural.
I thought maybe you could help. If by 'natural' you mean an object not designed but occurring as a result of instinct , then the beaver dam is natural but the strip mall is not. If you mean by 'natural' you mean present in nature , then everything is natural, including the strip mall. Just a quick note about St. John's Wort. Sometimes it works, sometimes it's placebo.
