• The question of what exists is often seen as one of the metaphysician’s primary concerns—an ontological stance is a central and basic component of a great many positions in metaphysics. Consider, in particular, the debate surrounding the metaphysics of time: the question of whether non-present entities exist is typically thought of as one of the fundamental issues at stake in the debate, with each position on the nature of time consisting in part of an answer to this question of ontology.

  • Difference-making grounds
    Stephan Krämer and Stefan Roski
    Philosophical Studies 174 (5): 1191-1215. 2017.
    We define a notion of difference-making for partial grounds of a fact in rough analogy to existing notions of difference-making for causes of an event. Using orthodox assumptions about ground, we show that it induces a non-trivial division with examples of partial grounds on both sides. We then demonstrate the theoretical fruitfulness of the notion by applying it to the analysis of a certain kind of putative counter-example to the transitivity of ground recently described by Jonathan Schaffer. F…Read more
  • Against explanatory realism
    Philosophical Studies 175 (1): 197-219. 2018.
    Explanatory realism is the position that all explanations give information about whatever metaphysically determines the explanandum. This view is popular and plays a central role in metaphysics, but in this paper I argue that explanatory realism is false. In Sect. 1 I introduce explanatory realism in its weak and strong versions, and discuss the argumentative work that explanatory realism is used for in contemporary metaphysics. In Sect. 2 I present a series of problem cases for explanatory real…Read more
  • Grounding and Metaphysical Explanation
    Proceedings of the Aristotelian Society 116 (3): 395-402. 2016.
    Attempts to elucidate grounding are often made by connecting grounding to metaphysical explanation, but the notion of metaphysical explanation is itself opaque, and has received little attention in the literature. We can appeal to theories of explanation in the philosophy of science to give us a characterization of metaphysical explanation, but this reveals a tension between three theses: that grounding relations are objective and mind-independent; that there are pragmatic elements to metaphysic…Read more
  • The Metaphysics of Identity: Is Identity Fundamental?
    Philosophy Compass 12 (1): 1-13. 2017.
    Identity and distinctness facts are ones like “The Eiffel Tower is identical to the Eiffel Tower,” and “The Eiffel Tower is distinct from the Louvre.” This paper concerns one question in the metaphysics of identity: Are identity and distinctness facts metaphysically fundamental or are they nonfundamental? I provide an overview of answers to this question.
  • Laws of Nature, Explanation, and Semantic Circularity
    Shumener Erica
    British Journal for the Philosophy of Science. 2017.
    Humeans and anti-Humeans agree that laws of nature should explain scientifically particular matters of fact. One objection to Humean accounts of laws contends that Humean laws cannot explain particular matters of fact because their explanations are harmfully circular. This article distinguishes between metaphysical and semantic characterizations of the circularity and argues for a new semantic version of the circularity objection. The new formulation suggests that Humean explanations are harmful…Read more
