In contemporary debates about ontology, one prominent skeptical view emphasizes the existence of different possible languages for doing ontology. Eli Hirsch, in recent years the most prominent proponent of a view like this, has defended the claim that “many familiar questions about the ontology of physical objects are merely verbal. Nothing is substantively at stake in these questions beyond the correct use of language” and the claim that “quantifier expressions can have different meaning in different languages”.1 Ted Sider, while critical of the type of view Hirsch defends, has in many places prominently singled it out for critical discussion. In his (2001), he associates with Carnap the view that “different frameworks employ different semantic rules for the quantifiers”, and says that a theorist in Carnap’s tradition would say that the stuff-ontologist and the thing-ontologist have different “frameworks” and that “[W]ithin these frameworks there are answers to what there is, but any question about which framework is the right framework is metaphysical in the pejorative sense of being a pseudo-question”.2 In his (forthcoming), Sider discusses at length the view that disputants in ontological disputes use the same sentences with different meaning and hence in fact each speak the truth, and what he describes as the attendant view that “there are multiple candidate meanings for the quantifiers”.3 In his (2005), Cian Dorr critically discusses “the idea that there are many different possible languages which differ systematically in the truth-values they assign to general ontological claims”.4..

We think of the world as consisting of objects, with properties and standing in relations. There are, to be sure, different views on what objects etc. there are, and on what their natures are. And some theorists want to subtract some elements from this picture. For example, the ontological nihilist says that there are no objects. But still, the view described is very much orthodoxy—so much orthodoxy that one may need to be reminded that the view that the world consists of objects, with properties and standing in relations is, precisely, a view. I here investigate the possibility that this view is false: that there is what may be called alien structure. And I investigate the relationship between alien structure and some important themes from the history of analytic philosophy.

Forthcoming in Darren Bradley (ed.), Carnap and Contemporary Philosophy. This paper is centered on Carnap’s views on rationality. More specifically, much of the focus is on a puzzle regarding Carnap’s view on rationality that Florian Steinberger has recently discussed. Not only is Steinberger’s discussion of significant intrinsic interest: his discussion also raises general questions about Carnap interpretation. As I have discussed in earlier work, there are two very different ways of interpreting Carnap’s talk of “frameworks” – and, relatedly, different ways of interpreting Carnap’s principle of tolerance. Carnap can be interpreted as either a relativist or as what I call a language pluralist. Steinberger’s puzzle arises given the relativist interpretation; I believe the language pluralist interpretation is correct. Most of the discussion will concern the correct interpretation of Carnap, and what this means for Steinberger’s puzzle. While I will not here mount a full defense of the language pluralist interpretation, I will pause to discuss Vera Flocke’s recent criticism of it. Towards the end, I will describe a puzzle regarding rationality different from Steinberger’s. The puzzle that I describe does arise already for the language pluralist

In his recent article "Carnapian Frameworks" (Synthese, 2021), Gabriel Broughton criticizes my discussions of Carnap on ontology and puts forward his own interpretation of what Carnap’s external/internal distinction amounts to. I here first argue that Broughton’s main claims about me are based on a misinterpretation. Then I turn to some issues of broader interest. I argue that Broughton’s own, potentially interesting interpretation of Carnap’s external/internal distinction does not work. And in light of Broughton’s discussion I present a sharpened version of what I have earlier said about Carnap’s this distinction.

In recent work, Amie Thomasson has defended what she calls normativism about metaphysical modality. She claims that discourse about metaphysical modality primarily serves a non-descriptive function, and builds a theory of such discourse around this claim. In this text, I critically discuss Thomasson’s view. Chief among the problems I go on to discuss is that Thomasson’s account of the meanings of modal expressions does not solve the problems she intends it to solve (among them solving the Frege-Geach problem), that there is no significant ordinary practice of making metaphysically modal claims in the first place, and that the general problem she identifies and seeks to solve goes beyond discourse about metaphysical modality so a theory focused on metaphysical modal discourse is not general enough to deal with the problem.

Oystein Linnebo's book Thin Objects is partly devoted to defending the view that some objects are “thin” in that their existence does not impose any substantive demands on the world. In this paper, I discuss the concern that the defense relies on there being entities that serve as the referents of predicates. Linnebo thus seems to assume the thinness of those entities. In the course of my discussion, I also discuss what Linnebo says about the role of criteria of identity in his discussion of reference and existence.

In recent work, Bengson, Cuneo, and Shafer‐Landau (2020) develop a new social version of moral intuitionism that promises to explain why our moral intuitions are trustworthy. In this paper, we raise several worries for their account and present some general challenges for the broader class of views we call Social Moral Intuitionism. We close by reflecting on Bengson, Cuneo, and Shafer‐Landau's comparison between what they call the “perceptual practice” and the “moral intuition practice”, which we take to raise some difficult normative and meta‐normative questions for theorists of all stripes.

In part of The Fragmentation of Being, Kris McDaniel discusses the possibility that we—persons—are not fully real, and the normative upshot of this. The broader metaphysical context is a view on which different things have different degrees of being and what is discussed is the possibility that persons do not have the maximal degree of being. McDaniel thinks that this has a problematic normative upshot: we would not matter. I do not agree. Here I go through some reasons for thinking that the possible metaphysical view discussed does not have the normative upshot that McDaniel thinks it has.

The aim of the paper is to bring clarity regarding the doctrine of quantifier variance (due to Eli Hirsch), and two prominent arguments against this doctrine, the collapse argument and the Eklund-Hawthorne argument. Different versions of the doctrine of quantifier variance are distinguished, and it is shown that the effectiveness of the arguments against it depends on what version of the doctrine is at issue. The metaontological significance of the different versions of the doctrine are also assessed. Roughly, quantifier variance concerns there being different possible existential quantifier meanings, and often the doctrine involves a claim to the effect there is no unique “best” quantifier meaning. Much of the discussion in the paper concerns what it is to be an existential quantifier meaning in the sense at issue.

According to a certain pluralist view in philosophy of mathematics, there are as many mathematical objects as there can coherently be. Recently, Justin Clarke-Doane has explored what consequences the analogous view on normative properties would have. What if there is a normative pluriverse? Here I address this same question. The challenge is best seen as a challenge to an important form of normative realism. I criticize the way Clarke-Doane presents the challenge. An improved challenge is presented, and the role of pluralism in this challenge is assessed.

In general, a reasonable method in philosophy is to replace an ordinary concept we actually use with a replacement concept better suited for theoretical purposes. But sometimes, due to features specific to the matter at hand, such replacement strategies are problematic. In this chapter, problems regarding the idea of replacing the concept of truth by an improved concept are discussed. Special attention is paid to the consequences of so‐called inconsistency theories of truth. A number of theorists including this chapter’s author have recently argued that the concept of truth is inconsistent. But considerations are presented here to the effect that even if the concept of truth is inconsistent, the idea of replacing it is not well motivated.

This is a review essay devoted to Pekka Väyrynen’s The Lewd, the Rude and the Nasty. Väyrynen’s book, concerned with thick terms and thick concepts, argues for a pragmatic view on the evaluativeness associated with these terms and concepts. The essay raises a number of critical questions regarding what Väyrynen’s arguments for his view actually show. It deals with, for example, thick properties, the fact-value distinction, what it is for terms and concepts to be (semantically) evaluative, and whether Väyrynen’s arguments generalize to thin evaluative concepts.
