I present and criticise Armstrong's most recent attempt to explain structural properties by means of the identification of universals with types of states of affairs and I state my own solution to the problem by appealing to formal relations holding between particulars.},author = {Joan Pag\`es},volume = {131},pages = {215--221}}@
