 Facts may be required in the theory of truth-making. States of affairs, by contrast, are supposed to pull their weight in the metaphysics of modality. According to Wittgenstein’s Tractatus Logico-Philosophicus, the totality of states of affairs exhausts the space of possibilities; the totality of states of affairs that obtain are the (actual) world. More recently, Alvin Plantinga (1974, 44) and Pollock (1984, 52) have posited in their metaphysics of possible worlds states of affairs that exists whether they obtain or not.
