This paper starts by distinguishing three views about the phenomenal character of perceptual experience. ‘Low-level theorists’ argue that perceptual experience is reducible to the experience of low-level properties, ‘high-level theorists’ argue that we have perceptual experiences of high-level properties, while ‘disunified view theorists’ argue that perceptual seemings can present high-level properties. The paper explores how cognitive states can penetrate perceptual experience and provides an interpretation of cognitive penetration that offers some support for the high-level view.

[Significantly updated in Chapter 7 of Awareness and the Substructure of Knowledge] Many have found it plausible that knowledge is a constitutively normative state, i.e. a state that is grounded in the possession of reasons. Many have also found it plausible that certain cases of proprioceptive knowledge, memorial knowledge, and self-evident knowledge are cases of knowledge that are not grounded in the possession of reasons. I refer to these as cases of basic knowledge. The existence of basic knowledge forms a (...) primary objection to the idea that knowledge is a constitutively normative state. In what follows I offer a way through the apparent dilemma of having to choose between either basic knowledge or the normativity of knowledge. The solution involves homing in on a state of awareness (≈non-accidental true representation) that is distinct from knowledge and which in turn grounds the normativity of knowledge in a way that is fully consistent with the existence of basic knowledge. An upshot of this is that externalist theories of knowledge turn out to be fully compatible with the thesis that knowledgeable beliefs are always beliefs that are justified by the reasons one possesses.

I review recent work on Phenomenal Conservatism, the position introduced by Michael Huemer according to which if it seems that P to a subject S, in the absence of defeaters S has thereby some degree of justification for believing P.

A number of philosophers, going back at least to Kierkegaard, argue that to have faith in something is, in part, to have a passion for that thing—to possess a lasting, formative disposition to feel certain positive patterns of emotion towards the object of faith. I propose that (at least some of) the intellectual dimensions of faith can be modeled in much the same way. Having faith in a person involves taking a certain perspective towards the object of faith—in possessing a (...) lasting, formative disposition for things to seem as though the object of faith is worthy of one’s trust. After developing the view, I briefly discuss its epistemic implications. I suggest that, by systematically reorienting how one experiences the world, faith can actually change one’s total body of evidence (or perhaps even how one weighs that evidence), thereby altering what one is justified in believing about the object of faith.

Alvin Plantinga theorizes the existence of a sensus divinitatis – a special cognitive faulty or mechanism dedicated to the production and non-inferential justification of theistic belief. Following Chris Tucker, we offer an evidentialist-friendly model of the sensus divinitatis whereon it produces theistic seemings that non-inferentially justify theistic belief. We suggest that the sensus divinitatis produces these seemings by tacitly grasping support relations between the content of ordinary experiences (in conjunction with our background evidence) and propositions about God. Our model offers (...) advantages such as eliminating the need for a sui generis religious faculty, harmonizing the sensus divinitatis with prominent theories in the cognitive science of religion, and providing a superior account of natural revelation.

The epistemic value of seemings is increasingly debated. Such debates are hindered, however, by a lack of consensus about the nature of seemings. There are four prominent conceptions in the literature, and the plausibility of principles such as phenomenal conservatism, which assign a prominent epistemic role to seemings, varies greatly from one conception to another. It is therefore crucial that we identify the correct conception of seemings. I argue that seemings are best understood as sui generis mental states with propositional (...) content and a distinct phenomenal character. Rival conceptions are shown to succumb to numerous difficulties. (shrink)

Perceptual Dogmatism holds that if it perceptually seems to S that p, then S has immediate prima facie justification for the belief that p. Various philosophers have made the notion of a perceptual seeming more precise by distinguishing perceptual seemings from both sensations and beliefs to accommodate a) the epistemic difference between perceptual judgments of novices and experts, and, b) the problem of the speckled hen. Using somewhat different terminology, perceptual seemings are supposed to be high-level percepts instead of low-level (...) sensations. I argue that although it is right that perceptual seemings should not be identified with sensations, they should also not be identified with percepts. There is no strong reason to assume that sensations and percepts exist as separate conscious states, and it appears therefore best to identify perceptual seemings simply with perceptual experiences interpreted as entities incorporating aspects from both sensations and percepts. However, even with this plausible identification in hand, the speckled hen will remain problematic for PD. (shrink)

It is still a live question in epistemology and philosophy of science as to what exactly evidence is. In my view, evidence consists in experiences called “seemings.” This view is a version of the phenomenal conception of evidence, the position that evidence consists in nonfactive mental states with propositional content. This conception is opposed by sense-data theorists, disjunctivists, and those who think evidence consists in physical objects or publicly observable states of affairs—call it the courtroom conception of evidence. Thomas Kelly (...) has recently argued that the phenomenal conception cannot play all the roles evidence plays and is thus inadequate. Having first explained the nature of seemings, in this essay I utilize Kelly’s own understanding of the four major roles of evidence and argue that the phenomenal conception can play each one. Experience is a good candidate for evidence. (shrink)

Phenomenal conservatives claim that seemings are sui generis mental states and can thus provide foundational non-doxastic justification for beliefs. Many of their critics deny this, claiming, instead, that seemings can be reductively analyzed in terms of other mental states—either beliefs, inclinations to believe, or beliefs about one’s evidence—that cannot provide foundational non-doxastic justification. In this paper, I argue that no tenable semantic reduction of ‘seems’ can be formulated in terms of the three reductive analyses that have been proposed by critics (...) of phenomenal conservatism. This is because Moore-paradoxical statements are generated when each of the reductive analyses is substituted for ‘seems’ in statements like ‘The stick is straight, but it does not seem to me that it’s straight.’ Since the latter statement is not Moore-paradoxical, the three proposed reductive analyses of ‘seems’ are unsuccessful. Absent a successful semantic reduction, however, there is no good reason to think a successful metaphysical reduction of seemings is forthcoming. Thus, there is an additional reason, unnoticed in the existing literature, to think that seemings are sui generis mental states. (shrink)

While there is no shortage of philosophical literature discussing knowledge by acquaintance, there is a surprising dearth of work about theories of epistemic justification based on direct acquaintance. This paper explores a basic framework for a thoroughly general account of epistemic justification by acquaintance. I argue that this approach to epistemic justification satisfies two importance aspects of justification. After sketching how the acquaintance approach can meet both objective and subjective aspects for epistemic justification, I will outline how this general account (...) of justification by acquaintance can be applied to the analysis of justification for many types of beliefs. Finally, some of the objections to the acquaintance approach will be considered and answered. (shrink)

Dogmatists and phenomenal conservatives think that if it perceptually seems to you that p, then you thereby have some prima facie justification for believing that p. Increasingly, writers about these views have argued that perceptual seemings are composed of two other states: a sensation followed by a seeming. In this article we critically examine this movement. First we argue that there are no compelling reasons to think of perceptual seemings as so composed. Second we argue that even if they were (...) so composed, this underlying disunity in metaphysical or psychological structure would fall below the threshold of epistemic significance. (shrink)

According to proper functionalist theories of warrant, a belief is warranted only if it is formed by cognitive faculties that are properly functioning according to a good, truth-aimed design plan, one that is often thought to be specified either by intentional design or by natural selection. A formidable challenge to proper functionalist theories is the Swampman objection, according to which there are scenarios involving creatures who have warranted beliefs but whose cognitive faculties are not properly functioning, or are poorly designed, (...) or are not aimed at truth. In this paper, we draw lessons from cognitive science in order to develop a novel argument for the conclusion that the Swampman objection fails against proper functionalist theories of warrant. Our argument not only shows that the underlying, central intuition motivating Swampman-like scenarios is false but also motivates proper function as a necessary condition for warrant, thereby lending support to the claim that any theory of knowledge that lacks a proper function requirement is false.

These replies to critical comments by Elijah Chudnoff, Noah Lemos, and Kevin McCain on my book Radical Skepticism and Epistemic Intuition begin (after the Introduction) with Section 2, where I address a cluster of complaints from Chudnoff and McCain in connection with skepticism-supporting underdetermination principles. (These principles play a significant role in my portrayal of radical skepticism and in my Reidian response to it.) In Section 3, I reply to some objections from Lemos concerning a claim (from Radical Skepticism and (...) Epistemic Intuition) that I call ‘the Paradigm-case Thesis’. In Section 4, I respond to some concerns that McCain and Lemos raise in connection with my discussion of the rationality of seemings. Lastly, Section 5 covers a few remaining objections from McCain and Lemos having to do with Chisholm’s “Problem of the Criterion,” the comparative strength of seemings, and the challenge of identifying which seemings count as epistemic intuitions.

Religious disagreement is, quite understandably, viewed as a problem for religious belief. In this paper, I consider why religious disagreement is a problem—why it is a potential defeater for religious belief—and I propose a way of dealing with this sort of potential defeater. I begin by focusing elsewhere—on arguments for radical skepticism. In section 1, I consider skeptical arguments proposed as potential defeaters for all of our perceptual and memory beliefs and explain what I think the rational response is to (...) such potential defeaters, emphasizing the way epistemic intuitions are involved in both the skeptical arguments and my recommended response. In section 2, I discuss the way in which peer disagreement—on any topic—is a potential defeater for our beliefs, highlighting the conditions under which recognized disagreement is a successful defeater and those under which it isn't. In the third section, I consider how to use a section-1 type of response to deal with a section-2 type of defeater for religious belief. (shrink)

The on-going debate over the ‘admissible contents of perceptual experience’ concerns the range of properties that human beings are directly acquainted with in perceptual experience. Regarding vision, it is relatively uncontroversial that the following properties can figure in the contents of visual experience: colour, shape, illumination, spatial relations, motion, and texture. The controversy begins when we ask whether any properties besides these figure in visual experience. We argue that ‘ensemble properties’ should be added to the list of visually admissible properties. (...) Ensemble properties are features that belong to a set of perceptible objects as a whole as opposed to the individuals that constitute that set. They include such features as the mean size of an array of shapes or the average emotional expression of an array of faces. Recent work in vision science has yielded compelling evidence that the visual system routinely encodes such properties. We argue that epistemological considerations provide strong reasons to think that these properties figure in visual experience. Judgements about ensemble properties are immediately warranted by our perceptual experience, and the only plausible way that a perceptual experience could confer this warrant is if it confers awareness of ensemble properties.

This paper defends the view that, in certain actual circumstances that aren’t uncommon for educated westerners, an awareness of the facts of religious disagreement doesn’t make theistic belief irrational. The first section makes some general remarks about when discovering disagreement (on any topic) makes it rational to give up your beliefs: it discusses the two main possible outcomes of disagreement (i.e., defeat of one’s disputed belief and demotion of one’s disputant), the main kinds of evidence that are relevant to demoting (...) one’s disputant, and the kinds of epistemic assessment involved in demoting a disputant. The second section argues that in cases of disagreement about theism, the theist’s evidence for theism and for the reliability of her theistic belief is often strong enough to support steadfastness in the face of disagreement. The third section argues that the theist’s evidence for the reliability of her disputant’s atheistic beliefs is often weak enough to allow her to rationally demote her atheist interlocutor and it explains how this demotion can occur in a sensible and appropriate way. The final section focuses on theists whose disagreement-based doubts about theism persist, despite the defenses offered on behalf of theism against such doubts. It concludes that these persistent doubts could in some cases result in defeaters for theistic belief, even if the doubts are irrational, but that the gift of faith can compensate for this. (shrink)

An introductory overview of the main issues in the epistemology of perception.

The epistemological problem of the external world asks: (1) “How is knowledge of the external world possible given certain obstacles which make it look impossible?” This is a “how-possible?” question: it asks how something is possible given certain obstacles which make it look impossible (cf. Cassam 2007; Nozick 1981; Stroud 1984). Now consider the following question, which asks: (2) “How is a philosophically satisfying answer to (1) possible?” Skepticism is the thesis that knowledge of the external world is impossible. It (...) therefore represents a negative answer to the first question. Meta-epistemological skepticism is the thesis that a satisfying philosophical explanation of how our knowledge of the external world is possible is itself impossible. It therefore represents a negative answer to the second question. In this thesis, I explore the prospects of meta-epistemological skepticism. In particular, I structure the thesis around two master arguments from for meta-epistemological skepticism. The first argument is that skepticism represents a kind of paradox which requires dispensing with a plausible principle or belief, or even 'platitude', which means that there's no philosophically satisfying response to the paradox (see, e.g., Stroud 1984), and the second argument is “Stroud’s dilemma” (cf. Cassam 2009), that either we explain how external world knowledge is possible by reference to what external world knowledge we have, thereby failing to answer the philosophical question adequately, or else we don't, but then we succumb to first-order skepticism. I argue that the first argument fails to provide adequate support for meta-epistemological skepticism. However, the second argument, Stroud’s dilemma, is plausible and withstands serious objections (e.g., from Sosa 1994, Williams 1996, and Cassam 2009). In short, while the worry emerging out of the 'skeptical paradox' view fails to adequately support meta-epistemological skepticism, Stroud’s dilemma succeeds. Fortunately, it doesn't show that we lack external world knowledge; we rather just can't explain, philosophically, how it's possible. We may have first-order knowledge without understanding how it's possible. This thesis therefore represents a partial defense of meta-epistemological skepticism. Meta-epistemological skepticism is a live option in epistemology. (shrink)

Philosophers and psychologists often distinguish episodic or personal memory from propositional or semantic memory. A vexed issue concerns the role, if any, of memory “impressions” or “seemings” within the latter. According to an important family of approaches, seemings play a fundamental epistemological role vis-à-vis propositional memory judgments: it is one’s memory seeming that Caesar was murdered, say, that justifies one’s judgment that he was murdered. Yet, it has been convincingly argued that these approaches lead to insurmountable problems and that memory (...) seemings are not wellsuited to play this justifying role. As a result, many contemporary accounts of propositional memory dispense with these seemings altogether. Is the idea that memory seemings play a key role in propositional memory really the result of bad theorizing? My aim is to shed light on this issue, which I will approach as follows. In Section 1, I contrast episodic memory with propositional memory so as to clarify the nature of the latter. According to the account I put forward, episodic memory consists in the preservation of acquaintance with objects and events, whereas propositional memory consists in the preservation of thought contents. In Section 2, I turn my attention to the contrast between propositional memory contents and propositional memory as an attitude. I argue that they play different roles. Memory contents satisfy a past awareness constraint and a causal constraint; the attitude of remembering explains why we are inclined to endorse these contents. This distinction leads me to explore the attitude of remembering, and I argue, in Section 3, that the most appealing account of this attitude is in terms of feelings of familiarity. In Section 4, I turn my attention to the epistemology of propositional memory and revisit the claim that propositional memory judgments are justifi ed by memory seemings. In so doing, I contend that the attitude of remembering plays an exclusively explanatory role and does not contribute to the epistemology of propositional memory judgments. I conclude by drawing a more general lesson regarding the respective roles of attitudes and contents. (shrink)

What we here show is two-fold. First, there is in certain sectors of the legal community a trend to pronounce negatively on the epistemic credentials of religious belief: many hold that religious belief as such is simply irrational. Our second claim is simply that religious belief need not be irrational: it is perfectly possible for religious believers to have epistemically justified religious beliefs. We discuss here several implications of our two-fold claim. The most important of these is simply that religious (...) citizens’ religious beliefs cannot be barred from the public square for any epistemological reason. (shrink)
