The chapter rehearses the main outlines of gatekeeping contextualism—the view that it is central to the concept of knowledge that attributions of knowledge function in a kind of epistemic gatekeeping for contextually salient communities. The case for gatekeeping contextualism is clarified within an extended discussion of the character of philosophical reflection. The chapter argues that normatively valenced, evaluative concepts constitute a broad class of concepts for which a sociolinguistic point or purpose may be readily sensed—and for which the intimate connection between point/purpose and the concept itself is readily understandable. Commonly at the inception of philosophical reflection one’s sense for the point or purpose of a specific concept is seldom highly articulate. The chapter argues that this does not prevent one’s grasp of point/purpose from doing real work in philosophical reflection.

We argue, primarily by appeal to phenomenological considerations related to the experiential aspects of agency, that belief fixation is broadly agentive; although it is rarely voluntary, nonetheless, it is phenomenologically agentive because of its significant phenomenological similarities to voluntary-agency experience. An important consequence is that epistemic rationality, as a central feature of belief fixation, is an agentive notion. This enables us to introduce and develop a distinction between core and ancillary epistemic virtues. Core epistemic virtues involve several inter-related kinds of epistemic rationality in belief fixation. Other “habits of mind” pertinent to belief fixation constitute ancillary epistemic virtues. Finally, we discuss the relationship between both kinds of virtues, offering a unified account of epistemic virtuousness.

Moral judgments are typically experienced as being categorically authoritative – i.e. as having a prescriptive force that is motivationally gripping independently of both conventional norms and one's pre-existing desires, and justificationally trumps both conventional norms and one's pre-existing desires. We argue that this key feature is best accommodated by the meta-ethical position we call ‘cognitivist expressivism’, which construes moral judgments as sui generis psychological states whose distinctive phenomenological character includes categorical authoritativeness. Traditional versions of expressivism cannot easily accommodate the justificationally trumping aspect of categorical authoritativeness, because they construe moral judgments as fundamentally desire-like. Moral realism cannot easily accommodate the aspect of inherent motivational grip, because realism construes moral judgments as a species of factual belief.

© Mind Association 2018Gila Sher’s Epistemic Friction is a bold and ambitious book, with many interesting things to say not only about knowledge, truth, and logic but also about matters ontological. It often requires the reader to construe it hermeneutically, but repays the effort of doing so.She coins the expression ‘epistemic friction’ to refer to constraints on a system of knowledge, coming from both the world and the mind. She says, ‘The world as the object or target of our theories restricts what we can truly say about it, and the mind restricts our theories both voluntarily and involuntarily’. Borrowing terminology from Shapiro, she describes her project as foundation without foundationalism. ‘The key idea’, she says, ‘… is that there is no inherent connection between grounding our system of knowledge in reality and...

Two philosophical questions arise about rationality in centipede games that are logically prior to attempts to apply the formal tools of game theory to this topic. First, given that the players have common knowledge of mutual rationality and common knowledge that they are each motivated solely to maximize their own profits, is there a backwards-induction argument that employs only familiar non-technical concepts about rationality, leads to the conclusion that the first player is rationally obligated to end the game at the first step, is deductively valid, employs premises all of which are prima facie highly plausible, and is prima facie sound and )? Second, if there is such an argument, then is it actually sound, or is it instead defective somehow despite being prima facie sound? Addressing these two questions is our project. We present a backwards-induction argument that is prima facie sound; we argue that it is an instance of the notorious sorites paradox, and hence that the concepts of rational obligatoriness and rational permissibility are vague; and we briefly address the potential consequences of all this for the foundations of game theory and decision theory.

I raise skeptical doubts about the prospects of Bayesian formal epistemology for providing an adequate general normative model of epistemic rationality. The notion of credence, I argue, embodies a very dubious psychological myth, viz., that for virtually any proposition p that one can entertain and understand, one has some quantitatively precise, 0-to-1 ratio-scale, doxastic attitude toward p. The concept of credence faces further serious problems as well—different ones depending on whether credence 1 is construed as full belief (the limit case of so-called partial belief) or instead is construed as absolute certainty. I argue that the notion of an “ideal Bayesian reasoner” cannot serve as a normative ideal that actual human agents should seek to emulate as closely as they can, because different such reasoners who all have the same evidence as oneself—no single one them being uniquely psychologically most similar to oneself—will differ from one another in their credences (e.g., because they commence from different prior credences). I argue that epistemic probability, properly understood, is quantitative degree of evidential support relative to one’s evidence, and that principled epistemic probabilities arise only under quite special evidential circumstances—which means that epistemic probability is ill suited to figure centrally within general norms of human epistemic rationality.

In the formation of epistemically justified beliefs, what is the role of attention, and what is the role (if any) of non-attentional aspects of cognition? We will here argue that there is an essential role for certain nonattentional aspects. These involve epistemically relevant background information that is implicit in the standing structure of an epistemic agent’s cognitive architecture and that does not get explicitly represented during belief-forming cognitive processing. Since such “morphological content” (as we call it) does not become explicit during belief formation, it cannot be information that is within the scope of attention. Nevertheless,it does exert a subtle influence on the character of conscious experience, rather than operating in a purely unconscious way.

In his 2013 Theoria article, “Unreliable Intuitions: A New Reply to the Moral Twin-Earth Argument,” Jorn Sonderholm attempts to undermine our moral twin earth argument against Richard Boyd's moral semantics by debunking the semantic intuitions that are prompted by reflection on the thought experiment featured in the MTE argument. We divide our reply into three main sections. In section 1, we briefly review Boyd's moral semantics and our MTE argument against this view. In section 2, we set forth what we take to be Sonderholm's master debunking argument, along with his proposed Boydian explanation of the semantic intuitions he seeks to debunk. Then in section 3, we mount our defence of the semantic intuitions under scrutiny, arguing on abductive grounds that, contrary to Sonderholm, the semantic intuitions generated by reflection on MTE scenarios are to be trusted in evaluating the plausibility of Boydian moral semantics. Section 4 is our summary and conclusion

For three decades the writings of Jaegwon Kim have had a major influence in philosophy of mind and in metaphysics. Sixteen of his philosophical papers, together with several new postscripts, are collected in Kim [1993]. The publication of this collection prompts the present essay. After some preliminary remarks in the opening section, in Section 2 I will briefly describe Kim's philosophical 'big picture' about the relation between the mental and the physical. In Section 3 I will situate Kim's approach on the larger philosophical landscape, vis-à-vis various other approaches frequently discussed in contemporary philosophy of mind. This comparative discussion will further illuminate Kim's own position, and also will serve as groundwork for subsequent discussion. In Section 4 I will point out certain persistent internal tensions in Kim's philosophical position on the mind--body problem, tensions that emerge especially clearly against the backdrop of Section 3's comparative discussion of Kim's position relative to various competing positions. In the remainder of the paper I will focus on two issues at the heart of his position, with particular attention to what he says about them in some of the more recent papers and the postscripts in Kim [1993]. First, how should a materialist understand the notion that the mental is 'determined' by the physical? More specifically, what role, if any, should be played by the concept of supervenience in explicating this kind of determination relation? Kim's views on this matter have recently changed, and I will discuss the issue with particular attention to his own latest remarks on it. This is the business of Section 5. Second, need a viable materialism assert that mentalistic psychology is reducible to neurobiology (and ultimately to physics)? More specifically, should a materialist insist on reducibility, despite the currently influential line of argument used by non-reductive materialists, the 'multiple realization' argument? On this matter too, Kim's views have changed somewhat; again, I will discuss the issue with particular attention to his recent thinking. This is the business of Section 6

Is conceptual relativity a genuine phenomenon? If so, how is it properly understood? And if it does occur, does it undermine metaphysical realism? These are the questions we propose to address. We will argue that conceptual relativity is indeed a genuine phenomenon, albeit an extremely puzzling one. We will offer an account of it. And we will argue that it is entirely compatible with metaphysical realism. Metaphysical realism is the view that there is a world of objects and properties that is independent of our thought and discourse (including our schemes of concepts) about such a world. Hilary Putnam, a former proponent of metaphysical realism, later gave it up largely because of the alleged phenomenon that he himself has given the label ‘conceptual relativity’. One of the key ideas of conceptual relativity is that certain concepts—including such fundamental concepts as object, entity, and existence—have a multiplicity of different and incompatible uses (Putnam 1987, p. 19; 1988, pp. 110 14). According to Putnam, once we recognize the phenomenon of conceptual relativity we must reject metaphysical realism: The suggestion . . . is that what is (by commonsense standards) the same situation can be described in many different ways, depending on how we use the words. The situation does not itself legislate how words like “object,” “entity,” and “exist” must be used. What is wrong with the notion of objects existing “independently” of conceptual schemes is that there are no standards for the use of even the logical notions apart from conceptual choices.” (Putnam 1988, p. 114) Putnam’s intriguing reasoning in this passage is difficult to evaluate directly, because conceptual [1] relativity is philosophically perplexing and in general is not well understood. In this paper we propose a construal of conceptual relativity that clarifies it considerably and explains how it is possible despite its initial air of paradox. We then draw upon this construal to explain why, contrary to Putnam and others, conceptual relativity does not conflict with metaphysical realism, but in fact comports well with it..

In Chapters 4 and 5 of his 1998 book From Metaphysics to Ethics: A Defence of Conceptual Analysis, Frank Jackson propounds and defends a form of moral realism that he calls both ‘moral functionalism’ and ‘analytical descriptivism’. Here we argue that this metaethical position, which we will henceforth call ‘analytical moral functionalism’, is untenable. We do so by applying a generic thought-experimental deconstructive recipe that we have used before against other views that posit moral properties and identify them with certain natural properties, a recipe that we believe is applicable to virtually any metaphysically naturalist version of moral realism. The recipe deploys a scenario we call Moral Twin Earth.

Inspired and informed by the work of Russ Hurlburt and Eric Schwitzgebel in their 'Describing Inner Experience', we do two things in this commentary. First, we discuss the degree of reliability that introspective methods might be expected to deliver across a range of types of experience. Second, we explore the phenomenology of agency as it bears on the topic of free will. We pose a number of poten-tial problems for attempts to use introspective methods to answer var-ious questions about the phenomenology of free-will experience -- questions such as this: does such experience have metaphysical-liber-tarian satisfaction conditions? We then discuss the prospects for over-coming some of these problems via approaches such as Hurlburt's DES methodology, the so-called 'talk aloud' protocol, and forms of abduction that combine introspection with non-introspection-based forms of evidence
