Somebody clever once said, "One can not hypostatize an abstract concept." If you try to you get threads like this one. Isn't there a difference between concrete and abstract concepts? Then why treat them the same way? A man may run swiftly, but not because he has swift. A child can act intellegently, but not because he has intellegence. You can mind your parents but not because you have a mind. A render can be done artfully but not because it is (or is not) "art." Humm?
