The ontological correlates of true law-statements must involve properties. How else can one pick our the uniformities which the law-statements entail?

Without properties we would be unable to express the laws of nature

A Reaction

I'm unconvinced about the 'laws', but I have to admit that it is hard to know how to describe the relevant bits of nature without some family of concepts covered by the word 'property'. I'm in favour of taking some of the family into care, though.
