Ordinarily when someone tells us something about her beliefs, desires or intentions, we presume she is right. According to standard views, this deferential trust is justified on the basis of certain epistemic properties of her assertion. In this paper, I offer a non-epistemic account of deference. I first motivate the account by noting two asymmetries between the kind of deference we show psychological self-ascriptions and the kind we grant to epistemic experts more generally. I then propose a novel agency-based account (...) of deference. Drawing on recent work on self-knowledge, I argue that a person normally has a distinctive type of cognitive agency; specifically she is able to constitute her psychological attitudes by making judgments about what they ought to be. I then argue that a speaker expresses this agentive authority when she self-ascribes a psychological attitude and this is what justifies deferentially trusting what she says. Because the notion of expression plays a central role in this account, I contrast it with recent neo-expressivist theories. (shrink)

The Capgras delusion is a condition in which a person believes that an imposter has replaced some close friend or relative. Recent theorists have appealed to Bayesianism to help explain both why a subject with the Capgras delusion adopts this delusional belief and why it persists despite counter-evidence. The Bayesian approach is useful for addressing these questions; however, the main proposal of this essay is that Capgras subjects also have a delusional conception of epistemic possibility, more specifically, they think more (...) things are possible, given what is known, than non-delusional subjects do. I argue that this is a central way in which their thinking departs from ordinary cognition and that it cannot be characterized in Bayesian terms. Thus, in order to fully understand the cognitive processing involved in the Capgras delusion, we must move beyond Bayesianism. 1 The Simple Bayesian Model2 Anomalous Evidence and the Capgras Delusion3 Impaired Reasoning4 Setting Priors5 Epistemic Modality6 Delusions of Possibility7 Delusions of Possibility in Different Contexts8 How Many Factors?

In a recent paper, Gray, Knickman, and Wegner present three experiments which they take to show that people perceive patients in a persistent vegetative state to have less mentality than the dead. Following on from Gomes and Parrott, we provide evidence to show that participants' responses in the initial experiments are an artifact of the questions posed. Results from two experiments show that, once the questions have been clarified, people do not ascribe more mental capacity to the dead than to (...) PVS patients. There is no reason to think that people perceive PVS patients as more dead than dead. (shrink)

Internalism and externalism disagree about whether agents who are internally the same can differ in their mental states. But what is it for two agents to be internally the same? Standard formulations take agents to be internally the same in virtue of some metaphysical fact, for example, that they share intrinsic physical properties. Our aim in this chapter is to argue that such formulations should be rejected. We provide the outlines of an alternative formulation on which agents are internally the (...) same in virtue of facts about their epistemic capacities. The resulting formulation is one on which internalism and externalism are views about the extent to which an agent’s mental states can vary independently of the capacity for introspective discrimination. We suggest that this epistemic formulation of internalism and externalism picks out a substantive disagreement in philosophical theorizing about the nature of the mind. (shrink)

In a recent paper, Gray, Knickman, and Wegner present three experiments which they take to show that people judge patients in a persistent vegetative state to have less mental capacity than the dead. They explain this result by claiming that people have implicit dualist or afterlife beliefs. This essay critically evaluates their experimental findings and their proposed explanation. We argue first that the experiments do not support the conclusion that people intuitively think PVS patients have less mentality than the dead. (...) And second, we provide an alternative explanation of our ascriptions of mentality to the dead and PVS patients, one which turns on Epicurean considerations about the nature of death. (shrink)
