Moral expressivism and sentential negation

This paper advances three necessary conditions on a successful account of sentential negation. First, the ability to explain the constancy of sentential meaning across negated and unnegated contexts (the Fregean Condition). Second, the ability to explain why sentences and their negations are inconsistent, and inconsistent in virtue of the meaning of negation (the Semantic Condition). Third, the ability of the account to generalize regardless of the topic of the negated sentence (the Generality Condition). The paper discusses three accounts of negation available to moral expressivists. The first—the dominant commitment account—fails to meet the Fregean Condition. The two remaining accounts—commitment semantics and the expression account—satisfy all three conditions. A recent argument that the dominant commitment account is the only option available to expressivists is considered and rejected.     

Moderate epistemic expressivism

The present paper argues that there are at least two equally plausible yet mutually incompatible answers to the question of what is of non-instrumental epistemic value. The hypothesis invoked to explain how this can be so—moderate epistemic expressivism—holds that (a) claims about epistemic value express nothing but commitments to particular goals of inquiry, and (b) there are at least two viable conceptions of those goals. It is shown that such expressivism survives recent arguments against a more radical form of epistemic expressivism, as well as two further arguments, framed in terms of the two most promising attempts to ground claims about epistemic value in something other than commitments to particular conceptions of inquiry. While this does not establish that moderate epistemic expressivism is true, its ability to explain a significant but puzzling axiological datum, as well as withstand strong counterarguments, makes clear that it is a theory to be reckoned with.     

Epistemic expressivism and the argument from motivation

This paper explores in detail an argument for epistemic expressivism, what we call the Argument from Motivation. While the Argument from Motivation has sometimes been anticipated, it has never been set out in detail. The argument has three premises, roughly, that certain judgments expressed in attributions of knowledge are intrinsically motivating in a distinct way (P1); that motivation for action requires desire-like states or conative attitudes (HTM); and that the semantic content of knowledge attributions cannot be specified without reference to the intrinsically motivating judgments that such attributions express (P2). We argue that these premises entail a version of ecumenical expressivism. Since the argument from motivation has not been explicitly stated before, there is no current discussion of the argument. In this paper we therefore consider and reject various objections that one might propose to the argument, including some that stem from the idea that knowledge is factive, or that knowledge involves evidence that rules out relevant alternatives. Other objections to (P1) specifically might be derived from cases of apparent lack of epistemic motivation considered in in Kvanvig (The value of knowledge and the pursuit of understanding, 2003) and Brown (Nous 42(2):167–189, 2008), as well as from general forms of externalism about epistemic motivation. We consider these and find them wanting. Finally, the paper offers some critical remarks about the prospect of denying (P2).     

Minimalist surface-colour matching

Some theories of surface-colour perception assume that observers estimate the illuminant on a scene so that its effects can be discounted. A critical test of this interpretation of colour constancy is whether surface-colour matching is worse when the number of surfaces in a scene is so small that any illuminant estimate is unreliable. In the experiment reported here, observers made asymmetric colour matches between pairs of simultaneously presented Mondrian-like patterns under different daylights. The patterns had either 49 surfaces or a minimal 2 surfaces. No significant effect of number was found, suggesting that illuminant estimates are unnecessary for surface-colour matching.     

Epistemology shmepistemology: moral error theory and epistemic expressivism

Some philosophers object to moral error theory by arguing that there a parity between moral and epistemic normativity. They maintain that moral and epistemic error theory stand or fall together, that epistemic error theory falls, and that moral error theory thus falls too. This paper offers a response to this objection on behalf of moral error theorists. I defend the view that moral and epistemic error theory do not stand or fall together by arguing that moral error theory can be sustained alongside epistemic expressivism. This unusual combination of theories can be underpinned by differences in the foundational norms that guide moral and epistemic inquiry. I conclude that the problem of epistemic normativity fails to show that it is compulsory for us to reject moral error theory.     

The meta-ethical dimension of the problem of evil

Conclusion In addition to complexity deriving from the notion of the possibility of a better world, the anti-theist argument from evils may possess the appearance of greater effectiveness than critical analysis should recognize it. If the moral language employed in the argument is accepted according to some forms of emotive, intuitive or theonomous interpretations, the so-called problem will vanish - and the question of the existence or nonexistence of God (so far as it is thought to depend on this argument) will be found to be settled, or at least appear settled, on the grounds simply of the usages involved. If it is stated in utilitarian language, on the other hand, the problem of evil has the logical status of a genuine problem. Since we are to affirm that the question: Is it evil that there are evils? is a legitimate question, we shall do best, I believe, to interpret the question in utilitarian language. So interpreted, the problem is such that both the theist and anti-theist should have to work at proving their respective claims regarding the evils in the world. Whether either should ever succeed, it seems that the meta-ethician will profit by analyzing the language in which the attempt (more strenuous for the theist, I should think) will be made.     

Logical expressivism,logical theory and the critique of inferences

Synthese - The basic idea of logical expressivism in the Brandomian tradition is that logic makes inferential relations explicit and thereby accessible to critical discussion. But expressivists...     

The meta-ethical significance of experiments about folk moral objectivism

The meta-ethical commitments of folk respondents – specifically their commitment to the objectivity of moral claims – have recently become subject to empirical scrutiny. Experimental findings suggest that people are meta-ethical pluralists: There is both inter- and intrapersonal variation with regard to people’s objectivist commitments. What meta-ethical implications, if any, do these findings have? I point out that current research does not directly address traditional meta-ethical questions: The methods used and distinctions drawn by experimenters do not perfectly match those of meta-ethicists. However, I go on to argue that, in spite of this mismatch, the research findings should be of interest to moral philosophers, including meta-ethicists. Not only do these findings extend the field of moral psychology with new data and hypotheses, but they also provide tentative evidence that touches on the adequacy of theses in moral semantics and moral metaphysics. Specifically, they put pressure on arguments in support of moral realism.

A Minimalist Theory of Truth

This article, after briefly discussing Alfred Tarski's influential theory of truth, turns to a more recent theory of truth, a deflationary, or minimalist, theory. One of the chief elements of a deflationary, or minimalist, theory of truth is that it replaces the question of what truth is with the question of what “true” does. After setting out the central features of the minimalist theory of truth, the article explains the motivation for opting for such a position. In addition, it provides some reasons for thinking that such a theory of truth is “minimal” or “deflationary” in the way that contemporary truth theorists have claimed it to be.
