Full Idea
If a hypothesised natural kind term fails to pick out a natural kind, keeping this theoretical term is likely to prevent the development of a new classification system that would identify the relevant kinds.

A Reaction
I'm persuaded. This is why metaphysicians should stop talking about 'properties'.
