The Realm of Reason develops a new, general theory of what it is for a thinker to be entitled to form a given belief. The theory locates entitlement in the nexus of relations between truth, content, and understanding. Peacocke formulates three principles of rationalism that articulate this conception. The principles imply that all entitlement has a component that is justificationally independent of experience. The resulting position is thus a form of rationalism, generalized to all kinds of content. To show how (...) these principles are realized in specific domains, Peacocke applies the theory in detail to several classical problems of philosophy, including the nature of perceptual entitlement, induction, and the status of moral thought. These discussions involve an elaboration of the structure of entitlement in ways that have applications in many other areas of philosophy. He also relates the theory to classical and recent rationalist thought, and to current issues in the theory of meaning, reference and explanation. In the course of these discussions, he proposes a general theory of the a priori. The focus of the work lies in the intersection of epistemology, metaphysics, and the theory of meaning, and will be of interest both to students and researchers in these areas, and to anyone concerned with the idea of rationality.

Being Known is a response to a philosophical challenge which arises for every area of thought: to reconcile a plausible account of what is involved in the truth of statements in a given area with a credible account of how we can know those statements. Christopher Peacocke presents a framework for addressing the challenge, a framework which links both the theory of knowledge and the theory of truth with the theory of concept-possession.

A stellar line-up of leading philosophers from around the world offer new treatments of a topic which has long been central to philosophical debate, and in ...

This paper is built around a single, simple idea. It is widely agreed that there is a distinctive kind of awareness each of us has of his own bodily actions. This action-awareness is different from any perceptual awareness a subject may have of his own actions; it can exist in the absence of such perceptual awareness. The single, simple idea around which this paper is built is that the distinctive awareness that subjects have of their own mental actions is a (...) form of action-awareness. Subjects’ awareness of their own mental actions is a species of the same genus that also includes the distinctive awareness of bodily actions. More specifically, I claim. (shrink)

What is involved in the consciousness of a conscious, "occurrent" propositional attitude, such as a thought, a sudden conjecture or a conscious decision? And what is the relation of such consciousness to attention? I hope the intrinsic interest of these questions provides sufficient motivation to allow me to start by addressing them. We will not have a full understanding either of consciousness in general, nor of attention in general, until we have answers to these questions. I think there are constitutive (...) features of these states which can be identified by broadly philosophical investigation, and in the early part of this paper I will try to do some of that identification. -/- Beyond the intrinsic interest of the topic, the nature of such conscious attitudes is highly pertinent to a philosophical account of psychological self-knowledge. So I will also say something about the significance of the constitutive features of these conscious attitudes for a philosophical account of how it can be that a thinker has a distinctive kind of knowledge of some of his mental states. The general challenge in this area is to find anything intermediate between the unexceptionable but uninformative, on the one hand, and the absolutely unbelievable on the other. (shrink)

This note aims to clarify which arguments do, and which arguments do not, tell against Conceptualism, the thesis that the representational content of experience is exclusively conceptual. Contrary to Sean Kelly’s position, conceptualism has no difficulty accommodating the phenomena of color constancy and of situation-dependence. Acknowledgment of nonconceptual content is also consistent with holding that experiences have nonrepresentational subjective features. The crucial arguments against conceptualism stem from animal perception, and from a distinction, elaborated in the final section of the paper, (...) between content which is objective and content which is also conceived of by its subject as objective.

The subjective properties of an experience are those which specify what having the experience is like for its subject. The sensational properties of an experience are those of its subjective properties that it does not possess in virtue of features of the way the experience represents the world as being (its representational content). Perhaps no topic in the philosophy of mind has been more vigorously debated in the past quarter-century than whether there are any sensational properties, so conceived. The existence (...) or otherwise of sensational properties is pivotal in assessing functionalism, representationalism, and many other conceptions of mental states and the nature of our ability to think about them. Instead of engaging in extended sentence- by-sentence dissection of these many discussions, I hope that the theses I formulate will, taken together, comprise a positive conception of sensational properties that can be drawn upon in assessing those debates. My main aim is to articulate that conception. (shrink)

I am going to argue for a robust realism about magnitudes, as irreducible elements in our ontology. This realistic attitude, I will argue, gives a better metaphysics than the alternatives. It suggests some new options in the philosophy of science. It also provides the materials for a better account of the mind’s relation to the world, in particular its perceptual relations.

Christopher Peacocke presents a new theory of subjects of consciousness, together with a theory of the nature of first person representation. He identifies three sorts of self-consciousness--perspectival, reflective, and interpersonal--and argues that they are key to explaining features of our knowledge, social relations, and emotional lives.

INTRODUCTION The philosophy of action and the philosophy of space and time may well seem to be unconnected areas. I will argue that in each of these areas ...

The openness of joint awareness between two or more subjects is a perceptual phenomenon. It involves a certain mutual awareness between the subjects, an awareness that makes reference to that very awareness itself. Properly characterized, such awareness can generate iterated awareness ‘x is aware that y is aware that x is aware...’ to whatever level the subjects can sustain. The openness should not be characterized in terms of Lewis–Schiffer common knowledge, the conditions for which are not met in many basic (...) cases of joint attention. A range of phenomena, including linguistic communication and other interpersonal relations, that have previously been described in terms of common knowledge should rather be seen as involving open joint awareness. An Appendix to this chapter discusses the relations of this approach to Barwise's discussions, and disputes the claim that these mental phenomena require the postulation of self-involving situations.

We often know what we are judging, what we are deciding, what problem we are trying to solve. We know not only the contents of our judgements, decidings and tryings; we also know that it is judgement, decision and attempted problem-solving in which we are engaged. How do we know these things?

Drawing upon a conception of the metaphysics of conscious states and of first-person content, we can argue that Descartes's transition ‘Cogito ergo sum’ is both sound and one he is entitled to make. We can nevertheless formulate a version of Lichtenberg's objection that can still be raised after Bernard Williams's discussion. I argue that this form of Lichtenberg's revenge can also be undermined. In doing so it helps to compare the metaphysics of subjects, worlds and times. The arguments also apply (...) to Descartes's ‘second Cogito’, that it is one and the same subject that thinks, wills, imagines. (shrink)

It seems to be an obvious truth that There could be something that doesn't actually exist. That is, it seems to be obiously true that ◊∃×). It is sufficient for the truth of that there could be more people, or trees, or cars, than there actually are. It is also sufficient for the truth of that there could be some pepole, or trees, or cars that are distinct from all those that actually exist. Do and suchlike statements involve a commitment (...) to possibilia, to things that possibly exist, but do not actually exist? If not, why not? And if so, what is the nature of the possibilia to which and its ilk commit us? These simple little questions are at the tip of an iceberg. (shrink)

Is there any good reason for thinking that a concept is individuated by the condition for a thinker to possess it? Why is that approach superior to alternative accounts of the individuation of concepts? These are amongst the fundamental questions raised by Wayne Davis.

If one were to write a book titled TheVarieties of Self-Consciousness, one would start off with some distinctions. It will help to locate my topic in relation to those distinctions.The first distinction concerns that kind of self-consciousness which involves only the minimal ability on the part of a subject to self-represent, to be in mental states with first person content, be it conceptual or nonconceptual. This minimal ability involves very little as compared with the more sophisticated states of which humans (...) are capable. First person content can be present in the perceptual states of a creature capable of representing only some of its physical states and its relations to the physical environment, and not capable of representing anything beyond that. So the first distinction is between this minimal case, and richer varieties of self-consciousness. Some writers use ‘self-conscious’ to apply to a subject who is in any mental state involving first person content, and so they would appl. (shrink)

This paper begins by considering Dummett's justificationist treatment of statements about the past in his book Truth and the Past (2004). Contrary to Dummett's position, there is no way of applying the intuitionistic distinction in the arithmetical case between direct and indirect methods of establishing a content to the case of past-tense statements. Attempts to do so either give the wrong truth conditions, or rely on notions not available to a justificationist position. A better, realistic treatment makes ineliminable use of (...) identity of state in its positive account of understanding of the past tense; this account can also be applied to other subject matters besides the past. A theory is developed of how realists should conceive of the relation between meaning and evidence. Points from this discussion are used in criticism of Wright's minimalist conception of truth. Three grades of possible involvement of truth and reference in a substantive theory of intentional content are distinguished, and reasons are given for thinking that a range of contents involve the highest degree of involvement of reference and truth in their substantive individuation.

Only computational explanations of a content‐involving sort can answer certain ‘how’‐questions; can support content‐involving counterfactuals; and have the generality characteristic of psychological explanations. Purely formal characteriza‐tions of computations have none of these properties, and do not determine content. These points apply not only to psychological explanation, but to Turing machines themselves. Computational explanations which involve content are not opposed to naturalism. They are also required if we are to explain the content‐involving properties of mental states.
