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

I am deeply indebted to Alex Byrne, Jonathan Cohen and Matthew McGrath for their careful, constructive, and penetrating comments on The Unity of Perception and I am grateful for the opportunity to clarify my view further.

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.

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)

Tyler Burge notably offers a truth‐first account of perceptual entitlement in terms of a priori necessary representational functions and norms: on his account, epistemic normativity turns on natural norms, which turn on representational functions. This paper has two aims: first, it criticises Tyler Burge's truth‐first a priori derivation on functionalist and value‐theoretic grounds. Second, it develops a novel, knowledge‐first a priori derivation of perceptual entitlement. According to the view developed here, it is a priori that we are entitled to believe (...) the deliverances of our perceptual belief formation system, in virtue of the latter's constitutive function of generating knowledge.

According to Schellenberg’s capacitism, perception is constituted by employing perceptual capacities to discriminate and single out particulars, including objects, events and property instances. To say that perception is so constituted, for her, is to say that perceptual states have the content, phenomenal character, and evidential force they do in virtue of the fact that they are yielded by employing perceptual capacities.1 1.

Representationalist theories of experience face the problem that two sets of compelling intuitions seem to support the contrary conclusions that we should ascribe, respectively, singular contents and general contents to experience. Susanna Schellenberg has, in a series of articles, argued that we can conserve both sets of intuitions if we award a central explanatory role to the notions of gappy-contents and content-schemas in our theory of experience. I argue that there is difficulty in seeing how gappy-contents and content-schemas can fulfil (...) the explanatory role envisioned for them by Schellenberg. The central problem is that both gappy-contents and contentschemas lack truth-conditions. Schellenberg attempts to support her view by suggesting an analogy between the role of content-schemas in our account of experience and the role of Kaplan’s notion of character in our account of demonstrative statements. However, I show that this analogy breaks down at crucial places when it is explored in detail. Hence, gappy-contents and content-schemas cannot fill the explanatory roles that the representationalist awards to fully truth-evaluable contents. Therefore, Schellenberg’s theory provides no way for the representationalist to conserve both sets of competing intuitions. (shrink)
