Diverse Populations are Conflated with Heterogeneous Collectives

The concept of difference has a long and important research tradition. We identify and explicate a heretofore overlooked distinction in the meaning and measurement of two different meanings of 'difference': 'diversity' and 'heterogeneity'. We argue that ‘diversity’ can describe a population well enough but does not describe a collective well. In contrast, ‘heterogeneity’ describes a collective better than a population and therefore ought to describe a collective. We argue that ignoring these distinctions can lead to a surprising and disturbing conflict between diversity and heterogeneity. In particular, focusing on the 'diversity' of human communities can be self-defeating for those who truly care about the importance of diversity, inclusion, and belonging.

The Defective Character Solution to the Non-identity Problem

The non-identity problem is that some actions seem morally wrong even though, by affecting future people’s identities, they are worse for nobody. In this paper, I further develop and defend a lesser-known solution to the problem, one according to which when such actions are wrong, it is not because of what they do or produce, but rather just because of why they were performed. In particular, I argue that the actions in non-identity cases are wrong just when and because they result from, or reflect in those who have performed them, a morally dubious character trait.

Against Schmought

Matti Eklund has argued that a new problem in metanormative theory arises when we consider the possibility of "normative counterparts"—normative concepts with the same normative roles as OUGHT and RIGHT (for instance), but with different extensions. I distinguish two versions of the problem, and propose a solution: when we attend to the attitudinal commitments involved in the possession and application of some normative concepts, we find that tolerance for the possibility of normative counterparts is rationally ruled out.

Putting I-Thoughts to Work

A traditional view holds that the self-concept is essentially indexical. In a highly influential article, Ruth Millikan famously held that the self-concept should be understood as a Millian name with a sui generis functional role. This article presents a novel explanatory argument against the Millian view and in favor of the indexical view. The argument starts from a characterization of the self-concept as a device of information integration. It then shows that the indexical view yields a better explanation of the integration function than the Millian view. The resulting account can rebut Millikan’s objections and it has broader implications for the debate on the essential indexical.

Quality-Space Functionalism about Color

I motivate and defend a previously underdeveloped functionalist account of the metaphysics of color, a view that I call ‘quality-space functionalism’ about color. Although other theorists have proposed varieties of color functionalism, this view differs from such accounts insofar as it identifies and individuates colors by their relative locations within a particular kind of so-called ‘quality space’ that reflects creatures’ capacities to discriminate visually among stimuli. My arguments for this view of color are abductive: I propose that quality-space functionalism best captures our commonsense conception of color, fits with many experimental findings, coheres with the phenomenology of color experience, and avoids many issues for standard theories of color such as color physicalism and color relationalism.

How Strong Is a Counterfactual?

The literature on counterfactuals is dominated by strict accounts (SA) and variably strict accounts (VSA). Counterexamples to the principle of Antecedent Strengthening were thought to be fatal to SA; but it has been shown that by adding dynamic resources to the view, such examples can be accounted for. We broaden the debate between VSA and SA by focusing on a new strengthening principle, Strengthening with a Possibility. We show dynamic SA classically validates this principle. We give a counterexample to it and show that extra dynamic resources cannot help SA. We then show VSA accounts for the counterexample if it allows for orderings on worlds that are not almost-connected, and that such an ordering naturally falls out of a Kratzerian ordering source semantics. We conclude that the failure of Strengthening with a Possibility tells strongly against Dynamic SA and in favor of an ordering source-based version of VSA.

On Meaning without Use

This paper defends the use-based metasemantic project against the problem of meaning without use, which allegedly shows the predictions of use-based metasemantic accounts to be indeterminate with respect to unusably long or complex expressions. This criticism is commonly taken to be decisive, prompting various retreats and contributing to the project’s eventual decline. Using metasemantic conventionalism as a case study, I argue the following: either such expressions do not belong to used languages or their meanings are uniquely determined by use. Thus, the alleged problem of meaning without use offers no challenge to the use-based metasemantic project generally, nor to conventionalism in particular.

A Sideways Look at Faithfulness for Quantum Correlations

Despite attempts to apply causal modeling techniques to quantum systems, Wood and Spekkens argue that any causal model purporting to explain quantum correlations must be fine tuned; it must violate the assumption of faithfulness. This paper is an attempt to undermine the reasonableness of the assumption of faithfulness in the quantum context. Employing a symmetry relation between an entangled quantum system and a “sideways” quantum system consisting of a single photon passing sequentially through two polarizers, I argue that Wood and Spekkens’s analysis applies equally to this sideways system also. As a result, we must either reject a causal explanation in this single photon system, or the sideways system must be fine tuned. If the latter, a violation of faithfulness in the ordinary entangled system may be more tolerable than first thought. Thus, extending the classical “no fine-tuning” principle of parsimony to the quantum realm may be too hasty.

Drifting and Directed Minds: The Significance of Mind-Wandering for Mental Agency

Perhaps the central question in action theory is this: what ingredient of bodily action is missing in mere behavior? But what is an analogous question for mental action? I ask this: what ingredient of active, goal-directed thought is missing in mind-wandering? My answer: attentional guidance. Attention is guided when you would feel pulled back from distractions. In contrast, mind-wandering drifts between topics unchecked. My unique starting point motivates new accounts of four central topics about mental action. First, its causal basis. Mind-wandering is a case study that allows us to tease apart two causes of mental action––guidance and motivation. Second, its experiential character. Goals are rarely the objects of awareness; rather, goals are “phenomenological frames” that carve experience into felt distractions and relevant information. Third, its scope. Intentional mind-wandering is a limit case of action where one actively cultivates passivity. Fourth, my theory offers a novel response to mental action skeptics like Strawson.
