Abstract

Fine has introduced an important distinction between constitutive and consequential essence. The constitutive essence of an object comprises truths directly definitive of the object whereas the consequential essence comprises the class of truths following logically from the directly definitive truths (subject to certain constraints). Essence theorists then face a challenge: how shall we draw the line between the truths directly definitive of an object and those that are mere consequences of them? Fine offers an answer. We start with the object’s consequential essence and then filter out from its consequential essence the propositions that are there on account of being partly grounded in others. The object’s constitutive essence comprises what’s left. I argue against this account by presenting a range of cases where it is clear that certain truths ought to count as constitutively essential for certain objects but where Fine’s account rules them out.
