Christopher Peacocke

This collection of newly commissioned essays, edited by NYU philosophers Paul Boghossian and Christopher Peacocke, resumes the current surge of interest in the proper explication of the notion of a priori. The authors discuss the relations of the a priori to the notions of definition, meaning, justification, and ontology, explore how the concept figured historically in the philosophies of Leibniz, Kant, Frege, and Wittgenstein, and address its role in the contemporary philosophies of logic, mathematics, mind, and science. The editors’ Introduction familiarizes the reader with the issues that are to be explored in detail in later parts of the anthology.

The question must arise whether a doctrine which is attributed to all of Quine, Putnam, Davidson, Rorty, Gadamer, and Heidegger is possibly a doctrine which comes in more than one version. Even the most ardent taxonomist is likely to draw back from classifying the various actual and possible positions which emerge from the very tangled history of recent discussions of holism. This chapter approaches the matter by addressing a series of questions, starting with those which are most likely to arise in the mind of those philosophers who regard holism with a mixture of fascination and suspicion. It shows whether the Duhem‐Quine Thesis true and it supports meaning holism if it is true. The rational revisability of statements has loomed large in discussions of holism. It is plausible that semantic values are assigned to expressions in such a way that canonical methods involving those expressions are always truth‐preserving.

Normativity is both one of the most important and ubiquitous of phenomena and, despite its historical centrality to philosophy, one of the least understood. The idea that there might be objective, attitude-independent, truths about what we ought to do (morality), what we ought to believe (rationality) or what we ought to appreciate (aesthetics), has always seemed very puzzling to philosophers, even though ordinary thought seems steeped in such judgments. Up until quite recently, the received view was that there was no good way to make sense of such a realistic, objectivist construal of normativity, that we have to make do with one or another anti-realistic alternative, principally, Expressivism, some forms of Constructivism, or Relativism. However, the well-known difficulties with these anti-realist options have motivated philosophers, most especially younger ones, to take a fresh look at Realism and to assess and develop it in new ways. Sometimes the result is that Realism is seen to be better protected against classic objections than had been previously realized; at others, the result seems to be that Realism is even harder to defend, and perhaps even harder to understand, than traditional thinking had allowed. The upshot is a vigorous and stimulating debate that is just beginning to take shape and whose outcome is far from resolved. The main impulse behind the present volume was to commission new work on Normative Realism by a mix of senior and junior scholars to give the philosophical community a useful sense of the current state of play on this central topic. ...

The notion of explanatory priority is clarified. For A to be explanatory prior to B is for the correct account of the individuation of B to mention A, but not conversely. Exploring the relations of explanatory priority between entities does not involve the impossible enterprise of explaining why individuating conditions are as they are. Use-theoretic accounts of meaning and content are consistent with the claims of The Primacy of Metaphysics if they essentially involve a reference relation; and otherwise not. In the case of thought about abstract objects, we must distinguish between the enterprise of defining an expression and individuating an entity. When we do so, Fregean complaints about the project endorsing the principle “Individuation Precedes Representation” evaporate. The treatment of subjects of mental states in The Primacy of Metaphysics does not let in Johnston’s problematic ‘personites’, proper temporal segments of genuine subjects, once we distinguish: between multiplicity over time and multiplicity at a given time; between metaphysical conditions of individuation and merely ‘conceptual connections’; between the conditions under which something comes into existence, and the nature of that thing.

The goal of this paper is to use the dual resources of the contemporary theory of intentional content and the notion of experiencing something metaphorically as something else, which I have defended in my earlier work, to explain the distinctive character of musical experience. These resources are used to explain Felix Mendelssohn’s point that emotional content in music can be more specific than anything capturable in language; to give an account of the role of metaphor in musical experience that does not generate insoluble puzzles; to formulate a Principle of Acquaintance for the content of musical experience; to give a theory of intentional subjects or ‘personae’ in music, and their significance; to explain two ways of hearing action in music; and to elaborate the significance for musical experience of the fact that perception of music is perception of agency.

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.

The principal thesis of A Study of Concepts is that a concept is individuated by its possession condition. Concepts are here understood to be sliced as finely as epistemic possibility. So now and 6 o’clock are different concepts, even if, in context, they pick out the same time; likewise for the observational concept circular and the complex concept locus of coplanar points equidistant from a given point. In the simplest cases, a possession condition is stated by giving a true, individuating statement of the form.
