 We are back then to the problem of how to make sense of how a state of affairs involves properties and particulars. In order to solve it, we need to find a relation between the state of affairs a’s being F and a and being F that (i) does not make a and being F parts of the state of affairs, (ii) allows one to distinguish between necessarily co-obtaining states of affairs, and (iii) distinguishes the state of affairs a’s being F from other objects that, intuitively speaking, involve a and being F.
