Call the epistemological grounds on which we rationally should determine our ontological (or alethiological) commitments regarding an entity its arbiter of existence (or arbiter of truth). It is commonly thought that arbiters of existence and truth can be provided by our practices. This paper argues that such views have several implications: (1) the relation of arbiters to our metaphysical commitments consists in indispensability, (2) realist views about a kind of entity should take the kinds of practices providing that entity’s arbiters to align with respect to their metaphysical dependencies, (3) if realists take a kind of practice to provide grounds on which to affirm the existence of a kind of entity, they should turn to those same grounds when seeking to provide an epistemology of the relevant domain.

L.A. Paul calls “deep” the kind of essentialism according to which the essential properties of objects are determined independently of the context. Deep essentialism opposes “shallow essentialism”, of which David Lewis is said to be a prominent advocate. Paul argues that standard forms of deep essentialism face a range of issues (mainly based on an interpretation of Quinean skepticism) that shallow essentialism does not. However, Paul claims, shallow essentialism eliminates the very heart of what motivates essentialism, so it is better to be deep than shallow. Accordingly, she proposes a very sharp novel account of essentialism, which, while attempting to preserve some of the advantages of shallow essentialism over the classical forms of deep essentialism, can be deemed to be deep. In this paper, I compare Paul’s proposal for a kind of deep essentialism with Lewis’s account, as it is presented by Paul. My aim is to show that the differences between the two approaches are not as significant as Paul takes them to be, and that Paul’s account can be taken to be deeper than Lewis’s only at the cost of sacrificing the very idea at the bottom of deep essentialism. This might be taken to suggest that, if Paul is correct in asserting that shallow essentialism is better equipped to address some skeptical challenges, but it is generally preferable to be deep than shallow, then Lewis’s account should be re-evaluated, since, as shallow as it can be, it might be deeper than it looks.

In this paper, using Mark Schroeder’s (2008a) expressivist semantic framework for normative language as a case study, I will identify difficulties that even an expressivist semantic theory capable of addressing the Frege-Geach problem will encounter in handling the logical possibility of moral dilemmas. To this end, I will draw on a classical puzzle formulated by McConnell (1978) that the logical possibility of moral dilemmas conflicts with some of the prima facie plausible axioms of the standard deontic logic, which include obligation implies permission. On the tentative assumption that proponents of ethical expressivism should be generally committed to securing the logical possibility of moral dilemmas in their semantic theories, I will explore whether and how expressivists can successfully invalidate obligation implies permission within the framework developed by Schroeder. The case study eventually reveals that this can indeed be a hard task for expressivists. Generalizing from the case study, I will suggest that the source of the difficulty ultimately lies in the mentalist assumption of the expressivist semantic project that the logico-semantic relations exhibited by normative sentences should be modeled in terms of the psychological attitudes that speakers express by uttering them. My final goal will be to show that the difficulty expressivists face in dealing with the logical possibility of moral dilemmas is a reflection of the more general problem that their commitment to the mentalist assumption prevents them from flexibly adopting or dropping axioms in their semantic theories to get the right technical results.
