By the way, you’re kind of cheating in saying that as soon as a characteristic is attributed to a thing, it ceases to be an externally constructed attribute – i.e. by defining chess as a game with the rules of chess that we know and agree on, or by defining heavy as an internal property of heavy rocks, you’re ignoring the fact that the rules of chess are only as good as the institutionally-led social consensus that underlies them, and that the heaviness of a rock is only as good as the nearby massive object which it attracts and which attracts it.

Just a thought.
