Many of the arguments for and against robust moral realism parallel arguments for and against theism. In this article, I consider one of the shared challenges: the explanatory challenge. The article begins with a presentation of Harman's formulation of the explanatory challenge as applied to moral realism and theism. I then examine two responses offered by robust moral realists to the explanatory challenge, one by Russ Shafer-Landau and another by David Enoch. Shafer-Landau argues that the moral realist can plausibly respond (...) to the challenge in a way unavailable to theists. I argue that Shafer-Landau's response is implausible as it stands and that once revised, it will apply to theism just as well. I then argue that Enoch's response, to the extent that it is plausible, can be used to defend theism as well. (shrink)

Moral judgment commonly depends on intuition. It is also true, though less widely agreed, that ethical theory depends on it. The nature and epistemic status of intuition have long been concerns of philosophy, and, with the increasing importance of ethical intuitionism as a major position in ethics, they are receiving much philosophical attention. There is growing agreement that intuition conceived as a kind of seeming is essential for both the justification of moral judgment and the confirmation of ethical theories. This (...) paper describes several importantly different kinds of intuition, particularly the episodic kinds often called seemings. This is done partly by sketching numerous examples of intuition. Intuitive seemings and moral judgments based on them differ in content, basis, epistemic authority, and phenomenology. The paper explores these four dimensions of intuition and, in doing so, compares moral intuition with moral perception. The overall aim is to clarify moral phenomenology both descriptively and epistemologically and to support the view that intuitions are often discriminative responses to experience and have justificatory power analogous to the power of sense-perceptions.

According to infinitism, all justification comes from an infinite series of reasons. Peter Klein defends infinitism as the correct solution to the regress problem by rejecting two alternative solutions: foundationalism and coherentism. I focus on Klein's argument against foundationalism, which relies on the premise that there is no justification without meta-justification. This premise is incompatible with dogmatic foundationalism as defended by Michael Huemer and Time Pryor. It does not, however, conflict with non-dogmatic foundationalism. Whereas dogmatic foundationalism rejects the need for (...) any form of meta-justification, non-dogmatic foundationalism merely rejects Laurence BonJour's claim that meta-justification must come from beliefs. Unlike its dogmatic counterpart, non-dogmatic foundationalism can allow for basic beliefs to receive meta-justification from non-doxastic sources such as experiences and memories. Construed thus, non-dogmatic foundationalism is compatible with Klein's principle that there is no justification without meta-justification. I conclude that Klein's rejection of foundationalism. fails. Nevertheless, I agree with Klein that when in response to a skeptical challenge we engage in the activity of defending our beliefs, the number of reasons we can give is at least in principle infinite. I argue that this type of infinity is benign because, when we continue to give reasons, we will eventually merely repeat previously stated reasons. Consequently, I reject Klein's claim that the more reasons we give the more we increase the justification of our beliefs. (shrink)

This thesis is set out as a collection of self-standing essays. Throughout these essays, I try to illuminate a number of controversies surrounding the way in which delusions are formed, and relatedly, their nature and epistemic standing. In Chapter 2, after an introductory chapter, I flesh out a new ‘endorsement’ approach to the Capgras delusion, the main idea being that the delusion is formed by endorsing the content of a metaphorical-perceptual state in which a loved one is represented metaphorically as (...) an imposter. In Chapter 3, I take issue with the idea, prevalent in the literature, that Bayesian accounts of inference in delusions are best characterised as versions of ‘explanationism’. Taking one such influential account as a test case, I argue that it is no more or less compatible with the endorsement alternative, which says delusions are acquired non-inferentially from experience. In Chapter 4, I examine a recent critique of predictive processing theories of delusions, according to which such theories suffer two limitations: they fail to explain why an agent believes something delusional as opposed to nothing at all or something else; they fail to explain how delusional hypotheses are generated in the first place. I suggest ways in which these concerns might be addressed. In Chapter 5, I consider how the Spinozan theory of belief fixation can improve the prospects of doxasticism about delusions. Doxasticism has been criticised on the grounds that delusions typically do not abide by rational standards which we expect beliefs to conform to. If belief fixation is Spinozan, I argue, these deviations from rationality are not just compatible with, but supportive of, their status as beliefs. In Chapter 6, I ask whether misidentification delusions formed via endorsement processes have any measure of perceptual justification. To give the best chance of getting a ‘yes’ answer, I address the question from the perspective of perceptual dogmatism, as this appears the best option if we are to grant at least defeasible justifiedness to MDs. I argue that, even so, MDs are completely unjustified. (shrink)

Our main aims in this paper is to discuss and criticise the core thesis of a position that has become known as phenomenal conservatism. According to this thesis, its seeming to one that p provides enough justification for a belief in p to be prima facie justified (a thesis we label Standard Phenomenal Conservatism). This thesis captures the special kind of epistemic import that seemings are claimed to have. To get clearer on this thesis, we embed it, first, in a (...) probabilistic framework in which updating on new evidence happens by Bayesian conditionalization, and second, a framework in which updating happens by Jeffrey conditionalization. We spell out problems for both views, and then generalize some of these to non-probabilistic frameworks. The main theme of our discussion is that the epistemic import of a seeming (or experience) should depend on its content in a plethora of ways that phenomenal conservatism is insensitive to. (shrink)

We can know some things about each others' mental lives. The view that some of this knowledge is genuinely perceptual is getting traction. But the idea that we can see any of each others' mental states themselves - the Simple Perceptual Hypothesis - remains unpopular. Very often the view that we can perceptually know, for example, that James is angry, is thought to depend either on our awareness of James' expression or on the way James appears - versions of what (...) I call the Expressive Hypothesis. The Expressive Hypothesis is intuitive. But in this chapter I argue that it does not allow us to do away with the thought that we sometimes perceive people's mental states. I take my arguments to provide some tentative support for the Simple Perceptual Hypothesis. (shrink)
