Expressivism's problem in solving the Frege/Geach problem concerning unasserted contexts is evaluated in the light of Blackburn's own methodological commitment to assessing philosophical theories in terms of costs and benefits, notably quasi-realism's aim of minimising the ontological commitments of a broadly naturalistic worldview. The problem emerges when a competitor theory can explain the same phenomena at lower cost: the minimalist about truth has no problem with unasserted contexts whereas the quasi-realist/expressivist package does. However, this form of projectivism is supposed to be a local and contrastive thesis or the central metaphor of projection makes no sense. So in competition with minimalism, projectivism must - at least for non-contested areas of thought and language - presuppose non-minimal truth. This casts new light on Blackburn's proposal globally to revise the relations between logic and truth so as to model ethical discourse as tracking a notion of commitment to contents that can be either attitudinal or truh evaluable. Why globally revise logic, in order solely to explain the problem of unasserted contexts, when a rival view can do so much better according to the standards set by the quasi-realist? Why do so when a notion of non-minimal truth and a classical explanation of logic are already available to you, given the local and contrastive claims of quasi-realism?

This paper is a reply to Michael Lynch's "Truth, Value and Epistemic Expressivism" in Philosophy and Phenomenological Research for 2009. It argues that Lynch's argument against expressivism fails because of an ambiguity in the employed notion of an 'epistemically disengaged standpoint'.

Minimalism, Paul Horwich’s deflationary conception of truth, has recently received a makeover in form of the second edition of Horwich’s highly stimulating book Truth1. I wish to use this occasion to explore a thesis vital to Minimalism: that the minimal theory of truth provides an adequate explanation of the facts about truth. I will indicate why the thesis is vital to Minimalism. Then I will argue that it can be saved from objections only by tampering with the standards of adequate explanation —a move that deprives it from giving support to Minimalism. At the heart of Minimalism lies a theory of truth for propositions. It is called the minimal theory, or MT for short. It consists of a collection of axioms. Each axiom is a proposition of the form..

James Dreier (Philos Perspect 18:23–44, 2004) states what he calls the “Problem of Creeping Minimalism”: that metaethical Expressivists can accept a series of claims about meaning, under which all of the sentences that Realists can accept are consistent with Expressivism. This would allow Expressivists to accept all of the Realist’s sentences, and as Dreier points out, make it difficult to say what the difference between the two views is. That Expressivists can accept these claims about meaning has been suggested by Simon Blackburn on behalf of his “quasi-realist”. I argue against the assumption that there is a way to interpret the Realist’s sentences in a way that renders them consistent with Expressivism.

In this paper I will be concerned with the question as to whether expressivist theories of meaning can coherently be combined with deflationist theories of truth. After outlining what I take expressivism to be and what I take deflationism about truth to be, I’ll explain why I don’t take the general version of this question to be very hard, and why the answer is ‘yes’. Having settled that, I’ll move on to what I take to be a more pressing and interesting version of the question, arising from a prima facie tension between deflationism about truth and the motivations underlying expressivism for what I take to be two of its most promising applications: to indicative conditionals and epistemic modals. Here I’ll argue that the challenge is substantive, but that there is no conceptual obstacle to its being met, provided that one’s expressivism takes the right form.

My main task here is first to distinguish, and then to map out possibilities. I won’t be concerned to argue for a certain position as much as to argue that various combinations of positions are consistent. In particular, I want to argue that a commitment to minimalism about truth does not bring an automatic commitment to what has been called a minimalist theory of truth-aptitude: the claim that every assertoric sentence which is used in a systematic way will be either true or false. Nor does minimalism about truth bring a commitment to what has been called minimalism about reference: the claim that every word used in a systematic way will refer.

Expressivism and truth have had a rocky relationship; this paper is a move toward reconciliation. I’ll show how to give a semantics for ‘true’ and ‘false’ in the most promising expressivist framework I know of1, and explain how the resulting marriage can benefit both parties. This is because expressivists need an account of truth, and expressivism about truth itself has certain attractions in its own right. In particular, I’ll show in a rigorous way how expressivists can make good on the idea that valid arguments are truth-preserving, shed some light on the idea that truth is not a property, and explore an application to the paradox of the liar. But first, I need to explain what an expressivist semantics involves, and some of the background underlying the version of the view that I will depend on, here. The digression will take a while, but I promise a payoff at the end.

In this paper I explore why one might hope to, and how to begin to, develop an expressivist account of truth – that is, a semantics for ‘true’ and ‘false’ within an expressivist framework. I do so for a few reasons: because certain features of deflationism seem to me to require some sort of nondescriptivist semantics, because of all nondescriptivist semantic frameworks which are capable of yielding definite predictions rather than consisting merely of hand-waving, expressivism is that with which I am most familiar, and because I believe that certain problems about truth and particularly about paradox seem to me to look different, when seen through the lens of an expressivist theory. I don’t mean to defend such a theory in this paper, and indeed I have cast doubts on the ultimate prospects of the framework I will be employing here elsewhere.1 But I do think that seeing what an expressivist theory of truth would look like helps to shed light on both expressivism and on truth.

Minimalism is currently the received deflationary theory of truth. On minimalism, truth is a transparent concept and a deflated property of truth bearers. In this paper, I situate minimalism within current deflationary debate about truth by contrasting it with its main alternative―the redundancy theory of truth (according to which truth is a transparent concept but not a property). I also outline three of the primary challenges facing minimalism, its formulation, explanatory adequacy and stability, and draw some lessons for the soundness of its conception of truth.

Minimalism about truth-aptitude, if correct, would undercut expressivism about moral discourse. Indeed, it would undercut nonfactualism about any area of discourse. But it cannot be correct, for there are areas, about which people hold beliefs and make statements, to which nonfactualism uncontroversially applies. Or so I will argue. I will be thereby challenging John Divers and Alexander Miller’s [3] appeal to minimalism about truth-aptitude in defending a certain argument against expressivism about value. But I will not be defending expressivism. For what is wrong with minimalism about truth-aptitude is, in my view, also what is wrong with expressivism: both mistakenly assume that for an utterance to qualify as a statement or a psychological state as a belief, it must be capable of being true or false.
