When people say all things natural are good, I assume they mean, by extension, that all things human are bad. Or that only humans are bad. So they don’t consider humans to be natural, which always kills me.
I think what is really going on is some kind of attempt at understanding the role of morality. The assumption is that animals can’t make moral decisions, but humans can. We can understand the context of what we do, and decide to do an antisocial thing, or not. Animals don’t really have a choice. They just do what it is in their “nature” to do.
So, if I understand this correctly, the underlying issue is whether humans are separated from all other living creatures because of our ability to make moral choices. I guess, by definition, if you are incapable of making moral choices, then we can’t really make a moral judgment about you. So the rest of nature is, by default, good (assuming everything starts from goodness).
Following this, we can see that only humans can descend into badness or immorality. Ok. So what? Is this some discussion about original sin? Is it a discussion of existentialism? Does the fact that other creatures are amoral while humans can be immoral imply anything about how we should relate to the fauna of this world?
I think that people who say this are implying something like inborn amorality is good, and should be given some exalted status. Although for what, I have no idea. I guess it allows human choices to be problematic, but they are that way already. Perhaps it gives people an angle on which to claim humans are bad, or that our behavior is bad, or that if we hurt inborn amoral creatures we are bad.
Honestly, none of these things make sense to me. There has to be something deeper going on. Perhaps something religious? If there is nothing deeper, then this is a lot of fuss over nothing. Anyone have any ideas?
