The essays in this volume investigate the norms of reason--the standards which contribute to determining whether beliefs, inferences, and actions are rational. Nine philosophers and two psychologists discuss what kinds of things these norms are, how they can be situated within the natural world, and what role they play in the psychological explanation of belief and action. Current work in the theory of rationality is subject to very diverse influences ranging from experimental and theoretical psychology, through philosophy of logic and language, to metaethics and the theory of practical reasoning; this range is well represented here.

Marko Jurjako’s article “Self-deception and the selectivity problem” (Jurjako 2013) offers a very interesting discussion of intentionalist approaches to self-deception and in particular the selectivity objection to anti-intentionalism raised in Bermúdez 1997 and 2000. This note responds to Jurjako’s claim that intentionalist models of self-deception face their own version of the selectivity problem, offering an account of how intentions are formed that can explain the selectivity of self-deception, even in the “common or garden” cases that Jurjako emphasizes.

Recent Descartes scholarship has revised the traditional view of the Cartesian project as one of strictly deductive rationalism. This revision has particularly stressed the role of science in Descartes’ thought. The revisionist conception of Descartes also downplays the significance of the sceptical arguments offered in the First Meditation, seeing them as tools for ‘turning the mind away from the senses’ in the interest of Cartesian science, rather than as reflecting genuinely epistemological concerns. This paper takes issue with this aspect of the revisionist reading of Descartes. It argues that seeing scepticism as critically important for Descartes is independent of interpreting him as a canonical rationalist. In fact, it is precisely Descartes’ scientific thought and practice which make scepticism such a problem for him.

My topic in this paper is social understanding. By this I mean the cognitive skills underlying social behaviour and social coordination. Normal, encultured, non-autistic and non-brain-damaged human beings are capable of an impressive degree of social coordination. We navigate the social world with a level of skill and dexterity fully comparable to that which we manifest in navigating the physical world. In neither sphere, one might think, would it be a trivial matter to identify the various competences which underly this impressive level of performance. Nonetheless, at least as far as interpersonal interactions are concerned, philosophers show a rare degree of unanimity. What grounds our success in these interactions is supposed to be our common mastery of folk psychology

Recent work on Descartes has drastically revised the traditional conception of Descartes as a paradigmatic rationalist and foundationalist. The traditional picture, familar from histories of philosophy and introductory lectures, is of a solitary meditator dedicated to the pursuit of certainty in a unified science via a rigourous process of logical deduction from indubitable first principles. But the Descartes that has emerged from recent studies strikes a more subtle balance between metaphysics, physics, epistemology and the philosophy of science. There is much to be praised in this revaluation, but a dangerous amount of over-compensation has gone on, particularly in the reinterpretation of the role of sceptical doubt in Descartes' thought. This reinterpretion plays down the epistemological reasons for worrying about scepticism, suggesting that Cartesian physics is what ultimately drives the introduction of scepticism in the First Meditation.

Frames and framing make one dimension of a decision problem particularly salient. In the simplest case, framesprimeresponses (as in, e.g., the Asian disease paradigm, where the gain frame primes risk-aversion and the loss frame primes risk-seeking). But in more complicated situations frames can function reflectively, by making salient particular reason-giving aspects of a thing, outcome, or action. For Shakespeare's Macbeth, for example, his feudal commitments are salient in one frame, while downplayed in another in favor of his personal ambition. The role of frames in reasoning can give rise torational framing effects. Macbeth can prefer fulfilling his feudal duty to murdering the king, while also preferring bravely taking the throne to fulfilling his feudal duty, knowing full well that bravely taking the throne just is murdering the king. Such patterns ofquasi-cyclicalpreferences can be correct and appropriate from the normative perspective of how one ought to reason. The paper explores three less dramatic types of rational framing effects: (1) Consciously framing and reframing long-term goals and short-term temptations can be important tools for self-control. (2) In the prototypical social interactions modeled by game theory, allowing for rational framing effects solves longstanding problems, such as the equilibrium selection problem and explaining the appeal of non-equilibrium solutions (e.g., the cooperative solution in the Prisoner's Dilemma). (3) Processes for resolving interpersonal conflicts and breaking discursive deadlock, because they involve internalizing multiple and incompatible ways of framing actions and outcomes, in effect create rational framing effects.

This paper assesses Fodor’s well-known argument from multiple realizability to nonreductive physicalism. Recent work has brought out that the empirical case for cross-species multiple realizability is weak at best and so we consider whether the argument can be rebooted using a “thin” notion of intraspecies multiple realizability, taking individual neural firing patterns to be the realizers of mental events. We agree that there are no prospects for reducing mental events to individual neural firing patterns. But there are more plausible candidates for the neural realizers of mental events out there, namely, global neural properties such as the average firing rates of neural populations, or the local field potential. The problem for Fodor’s argument is that those global neural properties point towards reductive versions of physicalism.

Debates about bodily ownership and psychological ownership have typically proceeded independently of each other. This paper explores the relation between them, with particular reference to how each is illuminated by psychopathology. I propose a general framework for studying ownership that is applicable both to bodily ownership and psychological ownership. The framework proposes studying ownership by starting with explicit judgments of ownership and then exploring the bases for those judgments. Section 3 discusses John Campbell’s account of ψ-ownership in the light of that general framework, emphasizing in particular his fractionation of ψ-ownership into two dissociable components. Section 4 briefly presents an account of φ-ownership that I have developed in more detail elsewhere. Section 5 explores the suggestion, originating with Alexandre Billon, that there needs to be an integrated account of φ-ownership and ψ-ownership because depersonalization disorders typically involve breakdowns of both φ-ownership and ψ-ownership. The argument from depersonalization is not compelling, but Section 6 proposes a different way of reaching the same conclusion. Section 7 shows how reflecting on agency and practical reasoning offers a common thread between the models of φ-ownership and ψ-ownership discussed earlier in the paper.

In Bermúdez 2013 I argued against David Lewis’s well-known and widely accepted claim that Newcomb’s problem and the prisoner’s dilemma are really notational variants of a single problem. Mark Walker’s paper in this journal takes issue with my argument. In this note I show how Walker’s criticisms are misplaced. The problems with Walker’s argument point to more general and independently interesting conclusions about, first, the relation between deliberation and decision and, second, the differences between the prisoner’s dilemma, which is a strategic choice problem, and Newcomb’s problem, which is a parametric choice problem.

Victor Verdejo’s paper ‘On Having the Same First Person Thoughts’ introduces an interesting and fruitful framework for applying the type-token distinction to first person thoughts. He draws a three-way distinction between types, instantiable types, and instantiated types, and uses that distinction to open up a conceptual space for the possibility of shareable first person thoughts. This note distinguishes two types of interpersonal shareability and argues that Verdejo’s suggestions about instantiable types can only secure shareability of the first kind, but not the second. The author then shows how his own account of what he terms the token-sense of “I” succeeds in making possible this second type of interpersonal shareability, despite the criticisms in Verdejo’s paper.

Thinking about self-control takes us to the heart of practical decision-making, human agency, motivation, and rational choice. Psychologists, philosophers, and decision theorists have all brought valuable insights and perspectives on how to model self-control, on different mechanisms for achieving and strengthening self-control, and on how self-control fits into the overall cognitive and affective economy. Yet these different literatures have remained relatively insulated from each other. Self-Control, Decision Theory, and Rationality brings them into dialog by focusing on the theme of rationality. It contains eleven newly written essays by a distinguished group of philosophers, psychologists, and decision theorists, together with a substantial introduction, collectively offering state-of-the-art perspectives on the rationality of self-control and the different mechanisms for achieving it.

This paper critically evaluates Jonathan Lowe's arguments for his non-Cartesian substance dualism. Sections 1 and 2 set out the principal claims of NCSD. The unity argument proposed in Lowe is discussed in Section 3. Throughout his career Lowe offered spirited attacks on reductionism about the self. Section 4 evaluates the anti-reductionist argument that Lowe offers in Subjects of Experience, an argument based on the individuation of mental events. Lowe offers an inventive proposal that the semantic distinction between direct and indirect reference delineates the metaphysical boundary between self and world, and uses this as a further argument against reductionism about the self. This proposal is discussed in Sections 5 and 6.

This paper examines and defends the view that the immediate objects of visual perception, or what are often called sense data, are parts of the facing surfaces of physical objects-the naturalized sense data (NSD) theory. Occasionally defended in the literature on the philosophy of perception, most famously by G. E. Moore (1918-1919), it has not proved popular and indeed was abandoned by Moore himself. The contemporary situation in the philosophy of perception seems ripe for a revaluation of the NSD theory. however. The NSD theory allows us to accommodate the very real shortcomings in uncritical direct realism without postulating the existence of non-physical sense data in a way that has seemed to many incompatible with any robust form of philosophical naturalism.The argument to establish the NSD theory proceeds in two stages. In §II I argue against the direct realist that we perceive three-dimensional material objects in virtue of perceiving parts of their surfaces. The argument for this conclusion involves clearly distinguishing (in § I) between two notions that have tended to be run together in discussions of perception---namely, immediate perception and direct perception. In §III I argue against the sense-datum theorist that those parts of the surfaces of those objects are not themselves perceived in virtue of the perception of anything else.

Peter Menzies has developed a novel version of the exclusion principle that he claims to be compatible with the possibility of mental causation. Menzies proposes to frame the exclusion principle in terms of a difference-making account of causation, understood in counterfactual terms. His new exclusion principle appears in two formulations: upwards exclusion — which is the familiar case in which a realizing event causally excludes the event that it realizes — and, more interestingly, downward exclusion, in which an event causally excludes its realizer. This paper shows that one consequence of Menzies’s proposed solution to the problem of mental causation is a ubiquitous violation of the principle of closure — a fact that forces him into a trilemma to which we see no satisfactory response.

In their recent book The Inessential Indexical Herman Cappelen and Josh Dever take issue with what has become close to philosophical orthodoxy – the view, most often associated with John Perry and David Lewis, that psychological explanations are essentially indexical. Cappelen and Dever claim that claims of essential indexicality are typically driven by intuitions rather than supported by arguments. They issue a challenge to supporters of essential indexicality: Produce an argument to back up the intuitions. This paper answers their challenge.
