 Consider the ways in which causal and constitutive claims might pull apart in a case of a socially produced artifact. Representations expressing the concept watch are normally causally necessary for some materials to come to have the intrinsic features of a watch, but they are not metaphysically necessary. It is metaphysically possible, however unlikely, that we could walk across a heath and find (something with the intrinsic features of) a watch that had “always been there.”
