This book offers a novel account of the relationship of experience to knowledge. The account builds on the intuitive idea that our ordinary perceptual judgments are not autonomous, that an interdependence obtains between our view of the world and our perceptual judgments. Anil Gupta shows in this important study that this interdependence is the key to a satisfactory account of experience. He uses tools from logic and the philosophy of language to argue that his account of experience makes available an (...) attractive and feasible empiricism. (shrink)

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.

According to Gupta, there is a difficulty facing any attempt to answer this question. The difficulty has to do with the following phenomenon. The impact that any particular experience has on what the experiencing subject is entitled to believe will depend upon the concepts, conceptions, and beliefs – in short, upon the view – that the experiencing subject is entitled to hold when she has that experience.1 But what view she was entitled to hold when she had that experience depends (...) in turn upon what experiences she had before then. And what view those experiences made her entitled in holding depended, in turn, upon what view she was entitled to hold when she had those experiences, which depended in turn upon what experiences she had had before that, and so on. Given this interdependence, what could make it the case that a creature’s experience makes her entitled simpliciter to hold a view, and not simply entitled to hold a view conditional on having some other entitlements? And, just as puzzling, what could make it the case that a creature’s experience makes her obligated simpliciter to hold a view? It is this latter question that Gupta attempts to answer. (shrink)

Consider the skeptic about the external world. Let’s straightaway concede to such a skeptic that perception gives us no conclusive or certain knowledge about our surroundings. Our perceptual justification for beliefs about our surroundings is always defeasible—there are always possible improvements in our epistemic state which would no longer support those beliefs. Let’s also concede to the skeptic that it’s metaphysically possible for us to have all the experiences we’re now having while all those experiences are false. Some philosophers dispute (...) this, but I do not. The skeptic I want to consider goes beyond these familiar points to the much more radical conclusion that our perceptual experiences can’t give us any knowledge or even justification for believing that our surroundings are one way rather than another.

In this book, Christopher Peacocke proposes a general theory about what it is for a thinker to be entitled to form a given belief. This theory is distinctively rationalist: that is, it gives a large role to the a priori, while insisting that the propositions or contents that can be known a priori are not in any way “true in virtue of meaning” (and without in any other way denigrating these propositions as “trivial”, or as propositions that “tell us nothing (...) about the world”, or the like). Peacocke then applies this theory to several classical problems in epistemology — to the problem of how our sensory experiences can entitle us to form beliefs about the external world, to the problem of induction, and to the problem of what entitles us to form moral beliefs.

Anil Gupta's Empiricism and Experience is a stylish and stimulating contribution to our subject. My expectation is that those who disagree with some of its central theses will, like me, learn greatly from thinking through where and why they part company with Gupta's lucidly presented position. For the purposes of a Symposium, I select three points of disagreement. Each point in one way or another concerns the epistemic role of the content of experience.

This chapter addresses the problem: what is the contribution of experience to knowledge? It argues that the problem is best appreciated by reflection on two commonplace ideas about experience and knowledge—ideas that appear to be in some tension with one another. These ideas are labelled as “Insight of Empiricism” and the “Multiple-Factorizability of Experience”.
