Perception grounds demonstrative reference, yields singular thoughts, and fixes the reference of singular terms. Moreover, perception provides us with knowledge of particulars in our environment and justifies singular thoughts about particulars. How does perception play these cognitive and epistemic roles in our lives? I address this question by exploring the fundamental nature of perceptual experience. I argue that perceptual states are constituted by particulars and discuss epistemic, ontological, psychologistic, and semantic approaches to account for perceptual particularity.

Perceptions guide our actions and provide us with evidence of the world around us. Illusions and hallucinations can mislead us: they may prompt as to act in ways that do not mesh with the world around us and they may lead us to form false beliefs about that world. The capacity view provides an account of evidence that does justice to these two facts. It shows in virtue of what illusions and hallucinations mislead us and prompt us to act. Moreover, (...) it shows in virtue of what we are in a better epistemic position when we perceive than when we hallucination. In this paper, I develop the capacity view, that is, the view that perceptual experience has epistemic force in virtue of the epistemic and metaphysical primacy of the perceptual capacities employed in perception. By grounding the epistemic force of experience in facts about the metaphysical structure of experience, the capacity view is not only an externalist view, but moreover a naturalistic view of the epistemology of perceptual experience. So it is an externalist and naturalistic alternative to reliabilism. I discuss the repercussions of this view for the justification of beliefs and the epistemic transparency of mental states, as well as, familiar problem cases. (shrink)

I discuss an aspect of the relation between accounts of de se thought and the phenomenon of immunity to error through misidentification. I will argue that a deflationary account of the latter—the Simple Account, due to Evans —will not do; a more robust one based on an account of de se thoughts is required. I will then sketch such an alternative account, based on a more general view on singular thoughts, and show how it can deal with the problems I (...) raise for the Simple Account. (shrink)

This paper defends and develops the capacity view against insightful critiques from Matt McGrath, Adam Pautz, and Ram Neta. In response to Matt McGrath, I show why capacities are essential and cannot simply be replaced with representational content. I argue moreover, that the asymmetry between the employment of perceptual capacities in the good and the bad case is sufficient to account for the epistemic force of perceptual states yielded by the employment of such capacities. In response to Adam Pautz, I (...) show why a perceiver’s belief is better justified than the belief of someone who suffers a subjectively indistinguishable hallucination. I show, moreover, why the capacity view is compatible with standard Bayesian principles and how it accounts for degrees of justification. In response to Ram Neta, I discuss the relationship between evidence and rational confidence, as well as the notion of evidence in light of an externalism about perceptual content. (shrink)

This paper argues for a sufficient evidence condition on knowledge and I argue that there is no belief condition on knowledge.

Are perceptual experiences epistemically appraisable? In this paper, I argue, contra Siegel (Rationality of perception, Oxford 2017) that they are not (§§ 2–3). I also show how the problem of hijacked experience can be solved without endorsing the view that perceptual experience is epistemically appraisable (§§ 4–5). A key idea behind my proposal is a disjunctivist view on rationalising and epistemic powers of perceptual experience.

Critical discussion of Susanna Schellenberg's account of hallucination and perceptual evidence.

I argue that the ground of the epistemic force of perceptual states lies in properties of the perceptual capacities that constitute the relevant perceptual states. I call this view capacitivism, since the notion of a capacity is explanatorily basic: it is because a given subject is employing a mental capacity with a certain nature that her mental states have epistemic force. More specically, I argue that perceptual states have epistemic force due to being systematically linked to mind-independent, environ- mental particulars (...) via the perceptual capacities that constitute the perceptual states. Thus, capacitivism shows how the epistemic force of experience is grounded in metaphysical facts about experience. Capacitivism is a distinctive externalist view of evidence and knowledge that does not invoke reliability, remains stead- fastly naturalistic, and in recognizing a metaphysically substantive common elem- ent between perception and hallucination avoids any commitment to disjunctivism.

In this paper, I argue for phenomenology, Husserlian phenomenology to be precise, as providing a solid paradigm on how to determine and assess hallucination. To be more explicit, in the context of my deliberations, I analyze Susanna Schellenberg’s arguments for “phenomenal” evidence and “factive” evidence, as regards her evidential theory of perception. To pinpoint the inadequacies raised in her account of (the hallucinating) Hallie and (the veridically perceiving) Percy sharing any kind of evidence, I propose Edmund Husserl’s epistemic fulfillment as (...) a detailed epistemological analysis of perception, which takes into consideration the latter’s phenomenological complexity.

There is a recent surge in interest in agential accounts of perception, i.e. accounts where activity plays a central role in accounting for the nature of perceptions. Within this camp, Lisa Miracch...

This paper focuses on Schellenberg’s Capacitism about Phenomenal Evidence, according to which if one is in a phenomenal state constituted by employing perceptual capacities, then one is in a phenomenal state that provides phenomenal evidence. This view offers an attractive explanation of why perceptual experience provides phenomenal evidence, and avoids difficulties faced by its contemporary alternatives. However, in spite of the attractions of this view, it is subject to what I call “the alien experience problem”: some alien experiences (e.g. clairvoyant (...) experience) are constituted by employing perceptual capacities, but they do not provide phenomenal evidence. This point is illustrated by a counterexample which is similar to, but also different in some important respects from, Bonjour’s famous clairvoyant Norman example. At the end of the paper, I sketch a restricted version of Capacitism about Phenomenal Evidence by putting some etiological constraint on the perceptual capacities employed. (shrink)

This article employs a thumbs and thumbnails analysis to analyze the 85 most viewed Asian online porn thumbnails, videos, and their audiences’ comments to argue that cyberspace functions as a space of “affective simulation,” rather than simply as a space of representation. For these online viewers, the performativity of pain by Asian women porn stars functions as an entry point to access and externalize their affective excess.
