It is a commonplace that things persist, though thinkers disagree over what persistence consist in. Views about time are closely related to views about persistence, though some have questioned the compatibility of certain combinations, such as Jonathan Tallant’s recent argument that presentism is incompatible with all views of persistence, including endurantism. We believe that such arguments can be avoided with neutral definitions of the terms. However, a nearly exhaustive investigation of contemporary literature revealed that, except for two that we could find, all definitions of “persist,” “endure,” and derivatives are incompatible with presentism! And, the exceptions fail to capture endurantist intuitions about endurance. But we believe that present-friendly and intuitive definitions of these concepts can be given. In this paper we offer such definitions. We go on to apply our definitions to two sample cases, showing that if our neutral definitions are used, the arguments in the cases fail.

In chapter 3 of Love Divine, Jordan Wessling argues against glorificationism, the view that God primarily created for the sake of his glory, and for amorism, that God created primarily out of love for creation. His arguments are based in both scripture and natural theology. In this paper, I offer reasons to think that Wessling’s arguments are not successful. I then suggest that we remain agnostic about God’s primary motivation for creating the world while still affirming that he was motivated by both self-glorification and love for creation.

Trenton Merricks holds to a physicalist view of the Incarnation according to which the Son transformed into a physical object at the Incarnation. R. T. Mullins, in “Physicalist Christology and the Two Sons Worry,” claims that Merricks’s account is Nestorian since it entails that it is metaphysically possible for the human nature of Christ to be a person independently of the Son’s incarnation. While I am not a physicalist, in this essay I defend Merricks’s view against Mullins’s claim. I argue that if the Son is numerically identical to the body of Jesus, then it is not possible for the body of Jesus to exist independently of the Son’s incarnation.

In this dissertation, I defend an answer to the following question in the diachronic personal identity debate: what are the necessary and sufficient conditions for our persistence over time? Two popular approaches to answering this question are the psychological and the somatic approach. On the former approach, we persist in virtue of some sort of psychological continuity. So, some proponents of the psychological approach think that we cease to exist if we lose certain features of our psychology such as our memories, beliefs, and rationality. On the latter approach, we persist in virtue of some sort of physical continuity. Eric Olson defends a version of the somatic approach called animalism. On his view, we are numerically identical to biological organisms and we persist if and only if the organisms we are persist. Although Olson’s animalism has some benefits, it also faces some challenges. For example, many people would say that we go wherever our brains go (if we go anywhere at all) because our brains (more specifically, our cerebra) realize the aspects of our psychology traditionally associated with persons, such as memories, beliefs, rationality, and self-awareness. But on Olson’s animalism, our psychology has nothing to do with our persistence and we go wherever our bodies go rather than our cerebra. Following Aristotle and Aquinas, I lay out an animalist view of our persistence called hylomorphic animalism. On this view, we are numerically identical to rational animals, which are living bodies composed of prime matter and a rational soul. Furthermore, we persist if and only if the composite of matter and rational soul persists. I claim that hylomorphic animalism makes better sense of certain contemporary personal identity thought experiments than Olson’s animalism. For example, contra Olson, I argue that our psychology does have something to do with our persistence and that we go wherever our brains go.
