Brainaddict said:but phil, human beings *are* natural, in that they evolved and develop according to the same rules of the Universe as everyone else. Language and culture *can* be explained by recourse to nature, because when you get down to it, unless you believe in divine intervention theres's nothing *but* nature in existence.
Ideas exist, they're not natural, animals don't have them, we do, there's no need to believe in "divine intervention" to account for them.
