There have been times in the history of ethical theory, especially in this century, when moral realism was down, but it was never out. The appeal of this doctrine for many moral philosophers is apparently so strong that there are always supporters in its corner who seek to resuscitate the view. The attraction is obvious: moral realism purports to provide a precious philosophical good, viz., objectivity and all that this involves, including right answers to (most) moral questions, and the possibility of knowing those answers. In the last decade, moral realism has re-entered the philosophical ring in powerful-looking naturalistic form. ln this paper we provide a dialectical overview: we situate the new wave position itself, and also our objections to it, in the context of the evolving program of philosophical naturalism in 20th century analytic philosophy. We seek to show that although this new contender might initially look like championship material, it succumbs to punches surprisingly similar to those that knocked out the old-fashioned versions of naturalist moral realism.

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

David Marr provided an influential account of levels of description in classical cognitive science. In this paper we contrast Marr'ent with some alternatives that are suggested by the recent emergence of connectionism. Marr's account is interesting and important both because of the levels of description it distinguishes, and because of the way his presentation reflects some of the most basic, foundational, assumptions of classical AI-style cognitive science. Thus, by focusing on levels of description, one can sharpen foundational differences between classicism and potential non-classical conceptions of mentality that might emerge under the rubric of connectionism.

In recent years, defenses of moral realism have embraced what we call new wave moral semantics', which construes the semantic workings of moral terms like good' and right' as akin to the semantic workings of natural-kind terms in science and also takes inspiration from functionalist themes in the philosophy of mind. This sort of semantic view which we find in the metaethical views of David Brink, Richard Boyd, Peter Railton, is the crucial semantical underpinning of a naturalistic brand of moral realism that these philosophers favor--a view that promises to deliver a robust form of moral realism. We argue that new wave moral semantics leads, in one way or another, to moral relativism--a view that is incompatible with the kind of moral realism these philosophers aim to defend.

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
