Presentism, Actualism, and Fatalism

In recent papers, Philip Swenson (2016) has argued that presentism is incompatible with the conjunction of libertarianism and divine foreknowledge, and Michael Rea (2006) has argued that presentism is incompatible with the conjunction of libertarianism and bivalence. In this paper, I respond to Swenson’s and Rea’s arguments. In each case, I develop a parody argument that seeks to show that actualism -- the view that everything is actual -- is inconsistent with the conjunction of (in the case of Rea) libertarianism and bivalence and the conjunction of (in the case of Swenson) libertarianism and divine foreknowledge. Seeing how these parody arguments using actualism go wrong helps us see how the arguments using presentism go wrong. I conclude that we have not yet been provided with a sound argument that presentism is inconsistent with the conjunction of libertarianism and bivalence or that presentism is inconsistent with the conjunction of libertarianism and divine foreknowledge.
