Essence, Grounding, and Explanation

Chapter 20 David Kovacs’ “Essence, Grounding, and Explanation” sets out four different ways in which essence might be taken to relate to the notion of grounding or metaphysical explanation, i.e., the type of connection that is often expressed by means of non-causal “in virtue of” or “because”-claims: (i) Unity: essence and grounding belong to a unified set of explanatory concepts; (ii) Supplementation: essence and grounding both contribute in their own way to a distinctive type of explanation; (iii) Independence: essence is a sui generis notion with no straightforward conceptual links to grounding; and (iv) Irrelevance: essence is not an explanatory notion at all and therefore should not be viewed as connected to explanatory notions like grounding. As Kovacs brings out in the chapter, a wide variety of attitudes are represented in the literature even among philosophers who are sympathetic to the recent “hyperintensional” turn in metaphysics when it comes to the question of how the notions of essence and grounding interact with one another.
