 Representationalism: there are no possible states of affairs, only representations of possible states of affairs (see Lewis 1986: 146 who ascribes this view to Skyrms). These representations are set-theoretic constructs that contain as their members particulars and universals that occur in some facts. For example, if a’s being F and b’s being G are both facts, but the sentence “a is G” is false, there is no state of affairs a’s being G, but there is an ordered-pair that contains a and being G as its members.
