Some hold that beliefs arising out of certain sources such as perceptual experience enjoy a kind of entitlement—as one is entitled to believe what is thereby presented as true, at least unless further evidence undermines that entitlement. This is commonly understood to require that default epistemic entitlement is a non-evidential kind of epistemic warrant. Our project here is to challenge this common, non-evidential, conception of epistemic entitlement. We will argue that although there are indeed basic beliefs with default entitlement status, typically the kind of default entitlement they possess is primarily a matter of the evidential support that accrues to them, both synchronically and diachronically, from wider mental states beyond the specific sensory-perceptual experiences that spawn them. We will call this status evidentially embedded epistemic entitlement—as distinct from entitlement as commonly understood in the literature, which we will call evidentially insular. Epistemic entitlement normally is characterized in the manner set forth in the first paragraph above, viz., as a form of default epistemic warrant that a given belief possesses independently of any other beliefs. We suggest that not all evidential support is managed at the level of belief. Thus, leaves room for the possibility of an epistemically embedded kind of entitlement. Here we develop the needed conception of entitlement drawing on Henderson and Horgan’s ideas of a kind of “iceberg epistemology.”

Descriptions of social norms can be explanatory. The erotetic approach to explanation provides a useful framework. I describe one very broad kind of explanation-seeking why-question, a genus that is common to the special sciences, and argue that descriptions of norms can serve as an answer to such why-questions. I draw upon Woodward’s recent discussion of the explanatory role of generalizations with a significant degree of invariance. Descriptions of norms provide what is, in effect, a generalization regarding the kind of historically contingent system— a group or society, a generalization with a significant degree of invariance. Key Words: explanation • invariance • norms • social sciences • erotetic • laws.

The argument I present here is an example of the manner in which naturalizing epistemology can help address fairly traditional epistemological issues. I develop one argument against coherentist epistemologies of empirical knowledge. In doing so, I draw on BonJour (1985), for that account seems to me to indicate the direction in which any plausible coherentist account would need to be developed, at least insofar as such accounts are to conceive of justification in terms of an agent (minimally) possessing articul able reasons and arguments, as is standard. I end by indicating important elements of coherentist epistemology that can be salvaged in the face of my argument, provided we are willing to drop the traditional commitment to characterizing justification in terms of the structure of articulable argument.

Epistemic Evaluation aims to explore and apply a particular methodology in epistemology. The methodology is to consider the point or purpose of our epistemic evaluations, and to pursue epistemological theory in light of such matters. Call this purposeful epistemology. The idea is that considerations about the point and purpose of epistemic evaluation might fruitfully constrain epistemological theory and yield insights for epistemological reflection. Several contributions to this volume explicitly address this general methodology, or some version of it. Others focus on advancing some application of the methodology rather than on theorizing about it. The papers go on to explore the idea that purposes allow one to understand the conceptual demands on knowing, examine how purposeful epistemology might shed light on the debate between internalist and externalist epistemologies, and further develop the idea of purposeful epistemology.

Disagreement affords humans as members of epistemic communities important opportunities for refining or improving their epistemic situations with respect to many of their beliefs. To get such epistemic gains, one needs to explore and gauge one’s own epistemic situation and the epistemic situations of others. Accordingly, a fitting response to disagreement regarding some matter, p, typically will turn on the resolution of two strongly interrelated questions: (1) whether p, and (2) why one’s interlocutor disagrees with oneself about p. When one has high intellectual respect for one’s interlocutor, answering question (2) involves arriving at a sympathetic explanatory understanding of the interlocutor’s own epistemic attitude toward p. Sorting out (2) is an abductive matter. Further, so far as the abductive explanation conditions one’s epistemic take regarding (1), there will be an abductive character to one’s epistemic position with respect to whether p—even where one’s initial purchase on whether p was not an abductive matter. We explain here how this can be managed naturally and tractably.

In our work we have drawn attention to an aspect of conscious experience that we have labeled chromatic illumination, which consists of conscious appreciation of a large body of background information, and of the holistic relevance of this information to a cognitive task that is being consciously undertaken, without that information being represented by any conscious, occurrent, intentional mental state. We have also characterized the prototypical causal role of chromatic-illumination features of conscious intentional states, and we have detailed the specific kind of physical-to-mental supervenience situation that would need to obtain in order for a chromatically illuminated conscious intentional state to figure as a supervenient mental cause of one’s subsequent cognition and behavior. In this paper we answer two residual questions. The first is a “How possible?” question, asking whether such a supervenience scenario is really a coherent conceptual possibility, given that it posits a putative conscious feature of conscious experience that allegedly plays a conscious causal role that supposedly constitutes conscious appreciation of information not being consciously represented. The second is a “How plausible?” question, asking whether the details of such a physical-to-mental supervenience scenario can be spelled out in a way that makes actually plausible the claim that chromatic illumination actually gets physically implemented this way in the human brain. We argue that the supervenient causal efficacy of chromatically illuminated conscious experience is not only a genuine conceptual possibility, but also very plausibly can really occur in humans.

We respond to the central concerns raised by our commentators to our book, The Epistemological Spectrum. Casullo believes that our account of what we term “low-grade a priori” justification provides important clarification of a kind of philosophical reflection. However he objects to calling such reflection a priori. We explain what we think is at stake. Along the way, we comment on his idea of that there may be an epistemic payoff to making a distinction between assumptions and presumptions. In the book, we argued that an epistemically important form of nonaccidental reliability can be understood as a matter of processes being “transglobally reliable under modulational control.” Graham recommends another form of nonaccidental reliability, one rooted in evolutionary etiology. We explain why we think that the reliability of perceptual processes is best understood as turning of the kinds of modulational control that we highlight. We clarify how this approach represents a kind of reasonable epistemic patience—modulational control takes time, as it must turn on agents generating information about their own capacities and foibles. Lyons raises interesting questions regarding how (what we term) morphological content possessed by the agent can do the work that we set for it. We argue that it is necessary in order for agents to accommodate the background information that is relevant to many central problems of belief formation. We clarify how it can be expected to work

Yoshida considers two broad understandings of how social scientists can and should “describe and explain other cultures or their aspects under concepts of rationality” . In the one corner is a family of approaches that Yoshida finds deeply flawed: cultural interpretivist approaches. Five authors representative of this family are given fine chapter length examinations: Winch, Taylor, Geertz, Sahlins, and Obeyesekere. In the other corner is Yoshida’s favored approach: critical rationalism. This approach is associated with the intellectual descendants of Karl Popper—notably Jarvie and Agassi. It is presented in outline and treated as the clear winner. By virtue of not having the defects that are diagnosed in the interpretivist approaches, critical rationalism is presented as the fitting approach in the social sciences. This dialectical structure has two notable weaknesses: First, showing that one item, A, lacks the problems found in another item, B, should not be take ..

Naturalized epistemology is not a recent invention, nor is it a philosophical invention. Rather, it is a cognitive phenomena that is pervasive and desirable in the way of human epistemic engagement with their world. It is a matter of the way that one’s cognitive processes can be modulated by information gotten from those same or wider cognitive processes. Such modulational control enhances the reliability of one’s cognitive processes in many ways ‐ and judgments about objective epistemic justification consistently evince a reasonable demand for it. However, with suitable modulational control in place within an agent or a community of agents, the fitting cognitive processes take time to generate information that then engenders changes in processes and norms. Further, as there are significant historical and biographical contingencies involving trajectories through one’s environment, there are contingencies in the information and modifications that will be engendered by suitable modulational control. As a result, what makes for objectively justified belief at a time will vary ‐ as the fruits of suitable modulational control accrue over time. This is a moderate form of historicism about epistemic justification

We argue that introspection reveals a ubiquitous aspect of conscious experience that hitherto has been largely unappreciated in philosophy of mind and in cognitive science: conscious appreciation of a large body of background information, and of the holistic relevance of this information to a cognitive task that is being consciously undertaken, without that information being represented by any conscious, occurrent, intentional mental state. We call this phenomenon chromatic illumination. We begin with a phenomenological case study, involving an experience of joke-understanding in which the conscious aspect of chromatic illumination is especially vivid. Then we offer an account of the prototypical causal role of conscious intentional states, and we offer a contrasting account of the somewhat different prototypical causal role of conscious chromatic-illumination features of conscious intentional states. Finally, we describe the specific kind of physical-to-mental supervenience situation that needs to obtain in order for a chromatically illuminated conscious intentional state to figure as a supervenient mental cause that exerts both kinds of prototypical, content-appropriate, reasons-guidance vis-a-vis one’s cognition and behavior.

The papers in this issue all concern the normative standards by which we do or should regulate our joint epistemic lives in communities. Plausibly, reflection on how we should regulate ourselves—what one should insist on in one's own practice and that of one's epistemic partners—takes some cues from reflection on what we do insist on. The reverse is plausibly also the case. These papers also, more or less explicitly, suggest that our epistemic sensibilities themselves reflect the demands of epistemic practice within a community of interdependent agents.

On what has become the received view of the principle of charity, it is a fundamental methodological constraint on interpretation that we find peoples’ intentional states patterned in ways that are characterized by norms of rationality. This recommended use of normative principles of rationality to inform intentional description is epistemically unmotivated. To say that the received view lacks epistemic motivation is to say that to interpret as it recommends would be epistemically irresponsible ans, in important respects irrational. On the alternative that I recommend, descriptive psychological generalization are what properly inform interpretation. One can readily understand the epistemic motivations for so interpreting, for they are the familiar reasons for informing description with background descriptive information. No parallel motivations for the received view seems possible.

Rosenberg argues that intentional generalizations in the human sciences cannot be law-like because they are not amenable to significant empirical refinement. This irrefinability is said to result from the principle that supposedly controls in intentional explanation also serving as the standard for successful interpretation. The only credible evidence bearing on such a principle would then need conform to it. I argue that psychological generalizations are refinable and can be nomic. I show how empirical refinement of psychological generalizations is possible by considering concrete cases. A sufficiently detailed view of the role of psychological generalizations in interpretation allows us to find in psychological investigations instances of bootstrap testing.

By a macro-level feature, I understand any feature that supervenes on, and is thus realized in, lower-level features. Recent discussions by Kim have suggested that such features cannot be causally relevant insofar as they are not classically reducible to lower-level features. This seems to render macro-level features causally irrelevant. I defend the causal relevance of some such features. Such features have been thought causally relevant in many examples that have underpinned philosophical work on causality. Additionally, in certain typical biological cases, we conceive of causally relevant features at various compatible levels of analysis. When elaborated, these points make a strong prima facie case for macro-level causal relevance. However, we might abandon both the philosophical guideposts and the corresponding explanatory practice in the special sciences were we convinced that no reflective philosophical account could provide for the causal relevance there supposed. I show that such drastic measures are not necessary, for we can make sense of macro-level causal relevance by drawing on Paul Humphreys' recent work in ways suggested by the concrete examples considered here.
