Philosophers who advocate an ontology without events must show how sentences containing apparent reference to events can be systematically paraphrased, or "regimented," into sentences which avoid ontological commitment to these putative entities. Two alternative proposals are set forth for regimenting statements containing putatively event-denoting definite descriptions. Both proposals eliminate the apparent reference to events, while still preserving the validity of inferences sanctioned by the surface grammar of the regimented sentences.

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.

The philosophical account of vagueness I call "transvaluationism" makes three fundamental claims. First, vagueness is logically incoherent in a certain way: it essentially involves mutually unsatisfiable requirements that govern vague language, vague thought-content, and putative vague objects and properties. Second, vagueness in language and thought (i.e., semantic vagueness) is a genuine phenomenon despite possessing this form of incoherence—and is viable, legitimate, and indeed indispensable. Third, vagueness as a feature of objects, properties, or relations (i.e., ontological vagueness) is impossible, because of the mutually unsatisfiable conditions that such putative items would have to meet. In this paper I set forth the core claims of transvaluationism in a way that acknowledges and explicitly addresses a challenging critique by Timothy Williamson of my prior attempts to articulate and defend this approach to vagueness. I sketch my favored approach to truth and ontological commitment, and I explain how it accommodates the impossibility of ontological vagueness. I argue that any approach to the logic and semantics of vagueness that both (i) eschews epistemicism and (ii) thoroughly avoids positing any arbitrary sharp boundaries (either first-order or higher-order) will have to be not an alternative to transvaluationism but an implementation of it. I sketch my reasons for repudiating epistemicism. I briefly describe my current thinking about how to accommodate intentional mental properties with vague content within an ontology that eschews ontological vagueness. And I revisit the idea, which played a key role in my earlier articulations of transvaluationism, that moral conflicts provide an illuminating model for understanding vagueness.

In “Generalized Conditionalization and the Sleeping Beauty Problem,” Anna Mahtani and I offer a new argument for thirdism that relies on what we call “generalized conditionalization.” Generalized conditionalization goes beyond conventional conditionalization in two respects: first, by sometimes deploying a space of synchronic, essentially temporal, candidate-possibilities that are not “prior” possibilities; and second, by allowing for the use of preliminary probabilities that arise by first bracketing, and then conditionalizing upon, “old evidence.” In “Beauty and Conditionalization: Reply to Horgan and Mahtani,” Joel Pust replies to the Horgan/mahtani argument, raising several objections. In my view his objections do not undermine the argument, but they do reveal a need to provide several further elaborations of it—elaborations that I think are independently plausible. In this paper I will address his objections, by providing the elaborations that I think they prompt.

Existence monism is defended against priority monism. Schaffer's arguments for priority monism and against pluralism are reviewed, such as the argument from gunk. The whole does not require parts. Ontological vagueness is impossible. If ordinary objects are in the right ontology then they are vague. So ordinary objects are not included in the right ontology; and hence thought and talk about them cannot be accommodated via fully ontological vindication. Partially ontological vindication is not viable. Semantical theorizing outside the ontology room and semantical theorizing in the doorway. Existence monism is theoretically preferable to priority monism.

Moral phenomenology is concerned with the elements of one's moral experiences that are generally available to introspection. Some philosophers argue that one's moral experiences, such as experiencing oneself as being morally obligated to perform some action on some occasion, contain elements that (1) are available to introspection and (2) carry ontological objectivist purportargument from phenomenological introspection.neutrality thesisthe phenomenological data regarding one's moral experiences that is available to introspection is neutral with respect to the issue of whether such experiences carry ontological objectivist purport

A provocative ontological-cum-semantic position asserting that the right ontology is austere in its exclusion of numerous common-sense and scientific posits and that many statements employing such posits are nonetheless true. The authors of Austere Realism describe and defend a provocative ontological-cum-semantic position, asserting that the right ontology is minimal or austere, in that it excludes numerous common-sense posits, and that statements employing such posits are nonetheless true, when truth is understood to be semantic correctness under contextually operative semantic standards. Terence Horgan and Matjaz Potrc argue that austere realism emerges naturally from consideration of the deep problems within the naive common-sense approach to truth and ontology. They offer an account of truth that confronts these deep internal problems and is independently plausible: contextual semantics, which asserts that truth is semantically correct affirmability. Under contextual semantics, much ordinary and scientific thought and discourse is true because its truth is indirect correspondence to the world. After offering further arguments for austere realism and addressing objections to it, Horgan and Potrc consider various alternative austere ontologies. They advance a specific version they call "blobjectivism"--the view that the right ontology includes only one concrete particular, the entire cosmos, which, although it has enormous local spatiotemporal variability, does not have any proper parts. The arguments in Austere Realism are powerfully made and concisely and lucidly set out. The authors' contentions and their methodological approach--products of a decade-long collaboration--will generate lively debate among scholars in metaphysics, ontology, and philosophy.
