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.

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.

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.

Chris Frith’s target chapters contain a wealth of interesting experiments and striking theoretical claims. In these comments I begin by drawing out some of the key themes in his discussion of action and the sense of agency. Frith’s central claim about conscious action is that what we are primarily conscious of in acting is our own agency. I will review some of the experimental evidence that he interprets in support of this claim and then explore the following three questions about the awareness of agency: Should we locate the phenomena that Frith describes as awareness of agency at the personal level or at the subpersonal level? If we are indeed operating at the personal level, then should we think about awareness of agency as something we experience, or as something that we believe? If awareness of agency is to be understood experientially, is there what some authors have called “a sense of agency”, where this is understood to be a distinctive type of experience that accompanies agentive behaviors but is absent in behaviors that are not under the control of the agent? In what follows I argue that awareness of agency should be located at the personal level, and that we should think of it as something we experience. But I will reject the claim that there is a distinctive sense of agency.

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.

The existence of structures with non-trivial authomorphisms (such as the automorphism of the field of complex numbers onto itself that swaps the two roots of – 1) has been held by Burgess and others to pose a serious difficulty for mathematical structuralism. This paper proposes a model-theoretic solution to the problem. It suggests that mathematical structuralists identify the “position” of an n-tuple in a mathematical structure with the type of that n-tuple in the expansion of the structure that has a name for every element in it.

In this paper I explore a justification for transcendental idealism that emerges from the dialogue with philosophical scepticism in which Kant is on and off engaged throughout the Critique of Pure Reason. Many commentators, most prominently Strawson, have claimed that transcend‐ ental idealism is an unfortunate addition to the Critique, one that can profitably be excised in the interests of clarity and coherence. Against this general picture I urge that transcendental idealism is in fact a very natural consequence of some of the central doctrines of the Critical Philosophy. It is in the context of Kant's debate with scepticism that this emerges most clearly. Nonetheless, I argue that Kant's employment of transcendental idealism against the sceptic is seriously compromised by his postulating the existence of unknowable things‐in‐themselves. As long as he maintains that there are unknowable things‐in‐themselves which are responsible for our having the experience that we do have, his position seems to collapse into sceptical idealism. In the final section of the paper I suggest that the only possible escape from this difficulty would be to rule out the possibility of affirming that unknowable things‐in‐themselves exist. I also suggest that an argument to this effect exists in the Critique and that Kant's position would be more consistent had he adhered to it

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.

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.

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.

[Phenomenology of Bodily Perception] Since this is colloquium on phenomenological and experimental approaches to cognition I’d like to set up te problem I want to address in terms of two of the different strands that we find in Merleau-Ponty’s thinking about the phenomenology of the body. One of these strands is profoundly insightful. The other one, however, seems to me to be lacking in plausibility – or rather, to put it less confrontationally and more in keeping with the spirit of the colloquium, the second strand seems to stand in the way of there being a certain type of fruitful interaction between phenomenological and experimental approaches to cognition.

A number of authors have noted that the key steps in Fitch’s argument are not intuitionistically valid, and some have proposed this as a reason for an anti-realist to accept intuitionistic logic (e.g. Williamson 1982, 1988). This line of reasoning rests upon two assumptions. The first is that the premises of Fitch’s argument make sense from an anti-realist point of view – and in particular, that an anti-realist can and should maintain the principle that all truths are knowable. The second is that we have some independent reason for thinking that classical logic is not appropriate in this area. This paper explores these two assumptions in the context of Michael Dummett’s version of anti-realism, with particular reference to the argument from indefinite extensibility developed at various points in Dummett’s writings (e.g. Dummett 1991 Ch. 24). Dummett argues that certain concepts, the indefinitely extensible concepts, are such that we cannot form a clear and determinate conception of all the objects that fall under them. The most familiar examples of indefinitely extensible concepts are mathematical. Dummett discusses the concepts ordinal number, real number, and natural number, which are indefinitely extensible because any conception that one might form of their complete extension can be extended to a more inclusive conception (as, for example, in Cantor’s proof of the non-denumerability of the set of real numbers). This paper argues that the concept of a truth is indefinitely extensible. This gives a Dummettian anti-realist an independent motivation for rejecting the classical understanding of the quantifiers in this area. At the same time, however, it places in doubt the admissibility of the knowability principle, which seems to involve quantification over the “totality” of truths. As Dummett is at pains to point out (1991: 316), some sentences that purport to quantify over the extension of an indefinitely extensible concept plainly have a truth-value (we can truly say, for example, that every ordinal number has a successor, even though when we say that we are not quantifying over the set of all ordinals). But is the knowability principle one of these sentences?
