Divine law theories of metaethics claim that moral rightness is grounded in God’s commands, wishes and so forth. Expressivist theories, by contrast, claim that to call something morally right is to express our own attitudes, not to report on God’s. Ostensibly, such views are incompatible. However, we shall argue that a rapprochement is possible and beneficial to both sides. Expressivists need to explain the difference between reporting and expressing an attitude, and to address the Frege-Geach problem. Divine law theorists need to get past the Euthyphro dilemma, and to avoid moral externalism. This paper shows how a combined theory helps us to achieve this.

A difficulty is exposed in Allan Gibbard's solution to the embedding/Frege-Geach problem, namely that the difference between refusing to accept a normative judgement and accepting its negation is ignored. This is shown to undermine the whole solution.

After presenting a simple expressivist account of reports of probabilistic judgments, I explore a classic problem for it, namely the Frege-Geach problem. I argue that is a problem not just for expressivism, but for any reasonable account of ascriptions of graded judgments. I suggest that the problem can be resolved by appropriately modeling imprecise credences.

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?

Aesthetic judgements are autonomous, as many other judgements are not: for the latter, but not the former, it is sometimes justifiable to change one's mind simply because several others share a different opinion. Why is this? One answer is that claims about beauty are not assertions at all, but expressions of aesthetic response. However, to cover more than just some of the explananda, this expressivism needs combining with some analogue of cognitive command, i.e. the idea that disagreements over beuaty can occur, and when they do it is a priori that one side has infringed the norms governing aesthetic discourse. This combination can be achieved by reading Kant’s aesthetic theory in expressivist terms. The resulting view is a form of quasi-realism about beauty. The position has its merits, but cannot ultimately explain the phenomena which motivate it. This conclusion generalises to quasi-realism about other matters.

Expressivists, such as Blackburn, analyse sentences such as 'S thinks that it ought to be the case that p' as S hoorays that p'. A problem is that the former sentence can be negated in three different ways, but the latter in only two. The distinction between refusing to accept a moral judgement and accepting its negation therefore cannot be accounted for. This is shown to undermine Blackburn's solution to the Frege-Geach problem.
