Expressivism, Logic, Consistency, and Moral Dilemmas

On an expressivist view, ethical claims are understood as expressions of our attitudes, desires, and feelings. A famous puzzle for this view concerns the use of logic in ethical reasoning, and two standard treatments try to solve the puzzle by explaining logical inconsistency in terms of conflicting attitudes. I argue, however, that this general strategy fails: because we can reason effectively even in the presence of conflicting moral attitudes – in cases of moral dilemmas – avoiding these conflicts cannot be a ground for correct moral reasoning. The result is a dilemma for expressivists: if they take all kinds of attitudes to be under consideration, then conflict cannot play the required role, since attitudes can fail to be compatible in cases of moral conflict. If they restrict attention to ‘all-in attitudes’ or to intentions or plans, then there is an important notion of obligation, used in standard arguments – one for which conflicts are allowed – that they fail to capture. I explain why expressivists should be especially tolerant of conflicting attitudes, and I conclude that they should pursue a different strategy for grounding logical normativity.

Resolute Expressivism

Over the years, we have witnessed the rise of a metaethical cottage industry devoted to claiming that expressivist analyses cannot capture some allegedly important feature of moral language. In this paper, I show how Simon Blackburn's pragmatist method enables him to respond decisively to many of these objections. In doing so, I hope to call into question some prevailing assumptions about the linguistic phenomena that a metaethical theory should be expected to capture.     

Emergence,Supervenience, and Realization

In the first section of this paper, I articulate Jaegwon Kim's argument against emergent down ward causation. In the second section, I canvas four responses to Kim's argument and argue that each fails. In the third section, I show that emergent downward causation does not, contra Kim, entail overdetermination. I argue that supervenience of emergent upon base properties is not sufficient for nomological causal relationsbetween emergent and base properties. What sustains Kim's argument is rather the claim that emergent properties realized by base properties can have no causal powers distinct from those base properties. I argue that this is false.     

Charity, Supervenience, and Skepticism

In a number of articles Donald Davidson has argued that the charitable nature of his method of radical interpretation rules out the possibility of massive error and thus refutes Cartesian skepticism. The diversity of such arguments and the suggestions that are all being made under the name of the principle of charity have prompted a large body of conflicting responses, adding only to the obscurity of the issues that are generally associated with the question of skepticism. In this paper I propose to consider the debate in a new light by reconstruing the principle of charity as a supervenience constraint on belief attribution. This would help explain some of the puzzling features of Davidson's arguments, like the idea of an omniscient interpreter, and the ensuing commentaries. Having provided an analysis of the limitations of Davidson's arguments, I shall then suggest an alternative explanation of the purported necessity of the principle of charity. Finally, having construed the principle of charity as a supervenience constraint, I shall examine what consequences this construal has for the logical status of the principle itself and its alleged epistemic potentials.     

Composition,Contingency, and Local Supervenience

A growing number of philosophers have argued against the orthodoxy that the correct principle of composition will be a metaphysically necessary truth. With contingentism about composition a seemingly viable option, it would appear that would‐be necessitarians shoulder the burden of proof. The aim of this paper is to demonstrate that the contingentist, too, has a significant burden. I argue that nonbrutal principles of composition satisfy a principle according to which facts about whether or not a collection composes supervene on noncomposition facts that are spatiotemporally local to the collection. I further argue that the contingentist has reason to reject both brutal composition and the supervenience principle. This reveals a significant internal tension in the contingentist's position. Unless this tension can be resolved, there will be (defeasible) reason to prefer necessitarianism about composition.     

Perception, Causation, and Supervenience

What relation between an experience and a physical object makes the experience a perception of the object?¹ One common answer is that it is a certain kind of causal relation. The idea is that to perceive an object is just to undergo an experience appropriately caused by the object. This answer is incorrect. The reason is that perceiving an object does not supervene on the causal connection the object bears to the perceiver's experience. Whether or not a person perceives an object depends, in part, on conditions that could obtain or fail to obtain without variation in the causal processes (if any) by which the object causes the person's experience. In what follows, I explain and defend these claims.     

Sincerity and Expressivism

What is it for a speech-act to be sincere? A very tempting answer, defended by John Searle and others, is that a speech-act is sincere just in case the speaker has the state of mind it expresses. I argue that we should instead hold that a speech-act is sincere just in case the speaker believes that she has the state of mind she believes it expresses (Sections 1 and 2). Scenarios in which speakers are deluded about their own states of mind play an important role in arguing for this account. In the course of developing this account I also explore how it might make good use of the often neglected distinction between insincerity and mere non-sincerity (Section 2). After defending and developing my positive proposal, I explore its implications for debates over expressivism in meta-ethics (Sections 3 and 4).     

Representationalism,Symmetrical Supervenience and Identity

According to some representationalists (M. Tye, Ten problems of consciousness, MIT Press, Massachusetts, USA, 1995; W.G. Lycan, Consciousness and experience, MIT Press, Cambridge, Massachusetts, USA, 1996; F. Dretske, Naturalising the mind, MIT Press, Massachusetts, USA 1995), qualia are identical to external environmental states or features. When one perceives a red rose for instance, one is visually representing the actual redness of the rose. The represented redness of the rose is the actual redness of the rose itself. Thus redness is not a property of one’s experience but an externally constituted property of the perceived physical object. In this sense, qualia are out there, in the external world. Here, I argue that the main representationalist arguments to this effect, if successful, establish no more than a symmetrical supervenience relation between representational content and qualia, and that a supervenience relation alone (albeit symmetrical) doesn’t suffice for identity. This supervenience thesis between qualia and representational content leaves open the question as to the essential nature of qualia.

Supervenience,necessary coextension,and reducibility

Conclusion Supervenience in most of its guises entails necessary coextension. Thus theoretical supervenience entails nomically necessary coextension. Kim's result, thus strengthened, has yet to hit home. I suspect that many supervenience enthusiasts would cool at necessary coextension: they didn't mean to be saying anything quite so strong. Furthermore, nomically necessary coextension can be a good reason for property identification, leading to reducibility in principle. This again is more than many supervenience theorists bargained for. They wanted supervenience without reducibility. It is not always available for this mediating role.     

Elaborating Expressivism: Moral judgments,Desires and Motivation

According to expressivism, moral judgments are desire-like states of mind. It is often argued that this view is made implausible because it isn’t consistent with the conceivability of amoralists, i.e., agents who make moral judgments yet lack motivation. In response, expressivists can invoke the distinction between dispositional and occurrent desires. Strandberg (Am Philos Quart 49:81–91, 2012) has recently argued that this distinction does not save expressivism. Indeed, it can be used to argue that expressivism is false. In this paper I argue that expressivism is a much more complex thesis than Strandberg assumes. Once these complexities are acknowledged, Strandberg’s arguments are rendered ineffective and expressivism rendered more plausible.     

Love,Value and Supervenience*

Abstract

People are prone to ascribe value to persons they love. However, the relation between love and value is far from straightforward. This is particularly evident given certain views on the nature of love. Setting out from the idea that what causes us to have an attitude towards an object need not be found in the intentional content of the attitude, this paper depicts love as an attitude that takes non‐fungible persons as intentional objects. Taking this view as a starting point, the paper shows why it is difficult to combine with certain views on value. The main challenge comes from the idea that value judgments are universalizable. This view squares badly with the thought that the people whom we love are irreplaceable. Introducing the idea that properties may have different functions in the intentional content of the attitude, this paper determines what precisely it is about love that makes it hard to combine with universalizability. Moreover, it suggests two ways of meeting this challenge.     

Supervenience and neuroscience

The philosophical technical term “supervenience” is frequently used in the philosophy of mind as a concise way of characterizing the core idea of physicalism in a manner that is neutral with respect to debates between reductive physicalists and nonreductive physicalists. I argue against this alleged neutrality and side with reductive physicalists. I am especially interested here in debates between psychoneural reductionists and nonreductive functionalist physicalists. Central to my arguments will be considerations concerning how best to articulate the spirit of the idea of supervenience. I argue for a version of supervenience, “fine-grained supervenience,” which is the claim that if, at a given time, a single entity instantiates two distinct mental properties, it must do so in virtue of instantiating two distinct physical properties. I argue further that despite initial appearances to the contrary, such a construal of supervenience can be embraced only by reductive physicalists.
