When a train operator tells us that our train will be late ‘because of delays’, their attempt at explanation fails because there is insufficient distance between the explanans and the explanandum. In this paper, I motivate and defend an account of ‘explanatory distance’, based on the idea that explanations give information about dependence. I show that this account offers useful resources for addressing problem cases, including recent debates about grounding explanation, and the historical case of Molière’s dormitive virtue.

Recent metaphysics has turned its focus to two notions that are—as well as having a common Aristotelian pedigree—widely thought to be intimately related: grounding and essence. Yet how, exactly, the two are related remains opaque. We develop a unified and uniform account of grounding and essence, one which understands them both in terms of a generalized notion of identity examined in recent work by Fabrice Correia, Cian Dorr, Agustín Rayo, and others. We argue that the account comports with antecedently plausible (...) principles governing grounding, essence, and identity taken individually, and illuminates how the three interact. We also argue that the account compares favorably to an alternative unification of grounding and essence recently proposed by Kit Fine. (shrink)

This thesis is an exercise in comparative metaontology. I am centrally concerned with how one might choose between competing metaontological theories. To make my project tractable, I compare two contemporary metaontological approaches dominant in the literature: neo-Quineanism (N-Q) and neo-Aristotelianism (N-A). Peter van Inwagen, a representative of N-Q, claims that ontological inquiry should be conducted in the quantifier-variable idiom of first-order predicate logic; to know what exists, or what a theory says exists, we read our commitments off the regimented sentences (...) that we affirm as true. E.J. Lowe, a representative of N-A objects to N-Q and claims that ontology should be done directly; that it is a mostly a priori activity which is the indispensable intellectual foundation for all rational inquiry. Both metaontological accounts are questionable and there seems to be no decisive way to choose between them. I claim, however, that considerations concerning the explanatory nature of ontology is a key and under-studied factor with respect to ontological method, pointing a way to a possible candidate for metaontological theory choice. I conclude that van Inwagen’s N-Q metaontology is wanting in many respects and further, that he does not provide adequate reasons to dispense with explanation as a feature of ontological inquiry. While explanatory considerations are central to Lowe’s N-A metaontology, I claim that the best that can be hoped for with his particular approach is a form of explanatory antirealism. (shrink)

This encyclopedia article provides a procedural account of explication outlining each step that is part of the overall explicative effort (2). It is prefaced by a summary of the historical development of the method (1). The latter part of the article includes a rough structural theory of explication (3) and a detailed presentation of an examplary explication taken from the history of philosophy and the foundations of mathematics (4).
