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

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

This paper explores a position that combines contextualism regarding knowledge with the idea that the central point or purpose of the concept of knowledge is to feature in attributions that keep epistemic gate for contextually salient communities. After highlighting the main outlines and virtues of the suggested gate-keeping contextualism, two issues are pursued. First, the motivation for the view is clarified in a discussion of the relation between evaluative concepts and the purposes they serve. This clarifies why one's sense for the point of an evaluative concept ought to constrain and inform one's understanding of the concept. Second, the paper explores ways of avoiding a problem in the author's earlier development of gate-keeping contextualism. The initial development of the view opened the door to a form of skepticism that would hobble an important facet of our social-epistemic lives

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.

Alvin Goldman’s contributions to contemporary epistemology are impressive—few epistemologists have provided others so many occasions for reflecting on the fundamental character of their discipline and its concepts. His work has informed the way epistemological questions have changed (and remained consistent) over the last two decades. We (the authors of this paper) can perhaps best suggest our indebtedness by noting that there is probably no paper on epistemology that either of us individually or jointly have produced that does not in its notes and references bear clear testimony to the influence of Professor Goldman’s arguments. The present paper is no exception (and this would be a particularly inapt place to break with our tradition of indebtedness). Professor Goldman has produced a series of discussions that we find particularly important for coming to terms with the venerable idea that there may be truths that can be known a priori (Goldman 1992a, 1992b, 1999). We do not altogether follow his lead, while he draws on the idea that a priori justification has something to do with innateness or processess, we prefer to accentuate the idea that a priori justification turns on a conceptually grounded truths and access via acquired conceptual competence (at least in many significant philosophical cases). Still, in developing our understanding we have been aided by much that Professor Goldman says regarding concepts, conceptual competence, and related psychological processes. The influences should become progressively clear, particularly in the later sections of this paper. What would it take for there to be a priori knowledge or justification? We can begin by reflecting on a widely agreed on answer to this question—one that purports to identify something that would at least be adequate for a priori justification. The answer will then serve as one anchor for the present investigation, a bit of shared ground on which empiricists and rationalists can, and typically do, agree..

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

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.

The doctrine is familiar. In a sentence, a priori truths are those that are knowable on the basis of reflection alone (independent of experience) by anyone who has acquired the relevant concepts. This expresses the classical conception of the a priori. Of course, there are those who despair of finding any truths that fully meet these demands. Some of the doubters are convinced, however, that the demands, are somewhat inflated by an epistemological tradition that was nevertheless on to something of importance. These thinkers would then seek to reconceive the a priori somewhat--accommodating some of the classical demands within a "retentive analysis." Ultimately, we will urge a place for both the classical conception and a complementary revisionary but retentive conception as well.

Contemporary accounts of what it is for an agent to be justified in holding a given belief commonly carry substantive commitments concerning what cognitive processes can and should be like. In this paper, we argue that concern for the plausiblity of such psychological commitments leads to significant epistemological results. In particular, it leads to a multi-faceted epistemology in which elements of traditionally conflicting epistemologies are vindicated within a single epistemological account. We suggest thinking of the epistemologically relevant cognitive processes in terms of the metaphor of an iceberg--the accessible and articulable states that have been the exclusive focus of much epistemology must, for reasons that we explain, comprise only a proper subset of epistemologically relevant processing, even as only a part of an iceburg is exposed to view. When one focuses on the interaction of accessible states and articulable information, the structure of epistemic justification looks rather like what has been called structural contextualism (Timmons 1993, Henderson 1994b). It might also be called quasi-foundationalist. Yet, given the sort of creatures we are, in attending to our epistemological tasks we must rely on processing that is sensitive to information that we could not articulate, that is not accessible in the standard internalist sense. When one focuses on the full range of epistemologically important processes, the structure of what makes for justification may be rather more like that envisioned by some coherentists.

It seems that hope springs eternal for the cherished idea that norms (or normativeprinciples) explain actions or regularities in actions. But it also seems thatthere are many ways of going wrong when taking norms and normative principlesas explanatory. The author argues that neither norms nor normative principles—insofar as they are the sort of things with normative force—is explanatoryof what is done. He considers the matter using both erotetic and ontic models ofexplanation. He further considers various understandings of norms. Key Words: explanation • norms • social science • rationality.

In What Philosophers Know, Gary Gutting provides an epistemology of philosophical reflection. This paper focuses on the roles that various intuitive inputs are said to play in philosophical thought. Gutting argues that philosophers are defeasibly entitled to believe some of these, prior to the outcome of the philosophical reflection, and that they then rightly serve as significant (again defeasible) anchors on reflection. This paper develops a view of epistemic entitlement and applies it to argue that many prephilosophical convictions of the kind Gutting discusses would be just the sort of belief for which entitlement would plausibly be defeated from the start. They then could not properly play the role in philosophical reflection that Gutting envisions for them
