Disjunctivism about perceptual appearances, as I conceive of it, is a theory which seeks to preserve a naïve realist conception of veridical perception in the light of the challenge from the argument from hallucination. The naïve realist claims that some sensory experiences are relations to mind-independent objects. That is to say, taking experiences to be episodes or events, the naïve realist supposes that some such episodes have as constituents mind-independent objects. In turn, the disjunctivist claims that in a case of (...) veridical perception like this very kind of experience that you now have, the experiential episode you enjoy is of a kind which could not be occurring were you having an hallucination. The common strategy of arguments from hallucination set out to show that certain things are true of hallucinations, and hence must be true of perceptions. For example, it is argued that hallucinations must have non-physical objects of awareness, or that such states are not relations to anything at all, but are at best seeming relations to objects. In insisting that veridical perceptual experience is of a distinct kind from hallucination, the disjunctivist denies that any of these conceptions of hallucination challenges our conception of veridical perceptions as relations to mind-independent objects. More specifically, I assume that the disjunctivist advocates naïve realism because they think that this position best articulates how sensory experience seems to us to be just through reflection. If the disjunctivist is correct in this contention, then anyone who accepts the conclusion of the argument from hallucination must also accept that the nature of sensory experience is other than it seems to us to be. In turn, one may complain that any such error theory is liable to lead to sceptical consequences. A Humean scepticism about the senses launches a challenge about our knowledge of the world through questioning the conception we have of what sense experience is, and how it can provide knowledge of the world.

Against the traditional view, Alvin Goldman argues that logic, probability theory, and linguistic analysis cannot by themselves delineate principles of rationality or justified belief. The mind's operations must be taken into account.

Much as we would like to conceive empirical thought as rationally grounded in experience, pitfalls await anyone who tries to articulate this position, and ...

A disjunctivist conception of acting for reasons is introduced by way of showing that a view of acting for reasons must give a place to knowledge. Two principal claims are made. 1. This conception has a rôle analogous to that of the disjunctive conception that John McDowell recommends in thinking about perception; and when the two disjunctivist conceptions are treated as counterparts, they can be shown to have work to do in combination. 2. This conception of acting for reasons safeguards (...) the connection between considerations that move us to act in particular ways and considerations that favour our acting in particular ways.

A comparison of disjunctive theories of action and perception. The development of a theory of action that warrants the name, a disjunctive theory. On this theory, there is an exclusive disjunction: either an action or an event (in one sense). It follows that in that sense basic actions do not have events intrinsic to them.

Right now, I see a computer in front of me. Now, according to current philosophical orthodoxy, I could have the very same perceptual experience that I’m having right now even if I were not seeing a computer in front of me. Indeed, such orthodoxy tells us, I could have the very same experience that I’m having right now even if I were not seeing anything at all in front of me, but simply suffering from a hallucination. More generally, someone can (...) have the very same perceptual experience no matter whether she is enjoying a veridical perception of some mindindependent object, or merely hallucinating. What differs across these two kinds of case is not the kind of experience that she has, but rather the connections between her experience and the rest of the world. So say most philosophers.

A conception of recognitional abilities and perceptual-discriminative abilities is deployed to make sense of how perceptual experiences enable us to make cognitive contact with objects and facts. It is argued that accepting the emerging view does not commit us to thinking that perceptual experiences are essentially relational, as they are conceived to be in disjunctivist theories. The discussion explores some implications for the theory of knowledge in general and, in particular, for the issue of how we can shed light on (...) the nature of knowledge is if we do not aim to provide conceptual analyses of knowledge in terms of true belief plus something else. Consideration is also given how we can best make sense of the practical value that knowledge has for us. (shrink)

Inspired by the writings of J. M. Hinton (1967a, 1967b, 1973), but ushered into the mainstream by Paul Snowdon (1980–1, 1990–1), John McDowell (1982, 1986), and M. G. F. Martin (2002, 2004, 2006), disjunctivism is currently discussed, advocated, and opposed in the philosophy of perception, the theory of knowledge, the theory of practical reason, and the philosophy of action. But what is disjunctivism?

This essay surveys the varieties of disjunctivism about perceptual experience. Disjunctivism comes in two main flavours, metaphysical and epistemological.

What is the relationship between our perceptions and reality? What is the relationship between the mind and the body? These are questions with which philosophers have grappled for centuries, and they are topics of considerable contemporary debate as well. Hilary Putnam has approached the divisions between perception and reality and between mind and body with great creativity throughout his career. Now, in _The Threefold Cord: Mind, Body, and World,_ he expounds upon these issues, elucidating both the strengths and weaknesses of (...) current schools of thought. With his characteristic wit and acuity, Putnam offers refreshing solutions to some of philosophy's most vexing problems. Putnam first examines the problem of realism: is objective truth possible? He acknowledges the deep impasse between empirical and idealist approaches to this question, critiquing them both, however, by highlighting the false assumption they share, that we cannot perceive the world directly. Drawing on the work of J. L. Austin and William James, Putnam develops a subtle and creative alternative, which he calls "natural realism." The second part of the book explores the mind-body question: is the mind independent of our interactions with the physical world? Again, Putnam critically assesses two sharply antithetical contemporary approaches and finds them both lacking. _The Threefold Cord_ shows the entire mind-body debate to be miscast and draws on the later work of Wittgenstein, once more advancing original views on perception and thought and their relationship with both the body and the external world. Finally, Putnam takes up two related problems--the role of causality in human behavior and whether or not thoughts and sensations have an "existence" all their own. With Putnam's lucid prose and insightful examples, _The Threefold Cord_ loosens the Gordian knots into which philosophy has bound itself over the issue of epistemology. (shrink)

In “Internalism and Externalism,” Laurence BonJour suggests that the contemporary epistemological debate over internalism and externalism concerns the formulation of the justification or warrant condition in an account of knowledge. The internalist requires that for a belief to meet this condition, all of the necessary elements must be cognitively accessible to the believer, whereas the externalist claims that at least some such elements do not need to be accessible to the believer. BonJour gives an overview of this dispute. He suggests (...) that the opposition between the two views is less straightforward than has usually been thought. He proposes, in addition, that each of them has valuable roles to play in major epistemological issues, even though the internalist approach is more fundamental in an important way. (shrink)

Much of the recent debate regarding scepticism has focussed on a certain template sceptical argument and a rather restricted set of proposals concerning how one might deal with that argument. Throughout this debate the ‘Moorean’ response to scepticism is often cited as a paradigm example of how one should not respond to the sceptical argument, so conceived. As I argue in this paper, however, there are ways of resurrecting the Moorean response to the sceptic. In particular, I consider the prospects (...) for three such proposals in this regard: a classical epistemic internalist neo-Mooreanism, a classical epistemic externalist neo-Mooreanism, and a non-classical McDowellian epistemic internalist neo-Mooreanism, and maintain that the last two of these proposals (both of which make appeal to a disjunctivist account of perception, broadly conceived) merit further exploration. Indeed, I claim that a suitably qualified version of neo-Mooreanism would actually sit quite well with the general philosophical motivations behind other key anti-sceptical views and I argue that given this fact neo-Mooreanism is actually at a dialectical advantage relative to other views when it comes to dealing with the sceptical problem as it is typically conceived.

In this paper I argue that McDowell's brand of disjunctivism about perceptual knowledge is ill‐motivated. First, I present a reconstruction of one main motivation for disjunctivism, in the form of an argument that theories that posit a “highest common factor” between veridical and non‐veridical experiences must be wrong. Then I show that the argument owes its plausibility to a failure to distinguish between justification and warrant (where “warrant” is understood as whatever has to be added to true belief to yield (...) knowledge).

I know that the laptop on which I am writing these words is dusty. How do I know? I can see that it is dusty. Seeing that it is dusty is a way of knowing that it is dusty. How come? According to what I’m going to call the entailment view, ‘S sees that P’ entails ‘S knows that P’ and it is only because this is so that seeing that the laptop is dusty qualifies as a way of knowing (...) that it is dusty. Generalizing from this, the entailment view concludes that Φ-ing that P is a way of knowing that P if and only if ‘S Φs that P’ entails ‘S knows that P’. (shrink)

I focus on two questions: what is knowledge, and how is knowledge possible? The latter is an example of a how-possible question. I argue that how-possible questions are obstacle-dependent and that they need to be dealt with at three different levels, the level of means, of obstacle-removal, and of enabling conditions. At the first of these levels the possibility of knowledge is accounted for by identifying means of knowing, and I argue that the identification of such means also contributes to (...) a proper understanding of what knowledge is. (shrink)

An epistemological how-possible question asks how knowledge, or knowledge of some specific kind, is possible. Familiar epistemological how-possible questions include ‘How is knowledge of the external world possible?’, ‘How is knowledge of other minds possible?’ and ‘How is a priori knowledge possible?’ These are the three questions that I tackle in my book. In each case, I explain how and why the question arises and propose a way of answering it. The main negative claim of the book is that transcendental (...) arguments are of little use in answering how-possible questions. A transcendental demonstration of the necessity of a certain kind of knowledge does not amount to an explanation of its possibility. The main positive claim is that such questions call for what I describe as a multi-levels response. I give an account of the multi-levels approach and put it to use in explaining how various kinds of knowledge are possible.Epistemological how-possible questions are not directly concerned with whether knowledge is possible, but if we cannot explain how a certain kind of knowledge is possible then the reality of that kind of knowledge is called into question. How-possible questions are obstacle-dependent. We ask how knowledge …. (shrink)

Bill Brewer presents an original view of the role of conscious experience in the acquisition of empirical knowledge. He argues that perceptual experiences must provide reasons for empirical beliefs if there are to be any determinate beliefs at all about particular objects in the world. This fresh approach to epistemology turns away from the search for necessary and sufficient conditions for knowledge and works instead from a theory of understanding in a particular area.

This paper challenges the standard conception of memory as a form of knowledge. Unlike knowledge, memory implies neither belief nor justification.

Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

The aim of this paper is to sketch a theory of justified belief. What I have in mind is an explanatory theory, one that explains in a general way why certain beliefs are counted as justified and others as unjustified. Unlike some traditional approaches, I do not try to prescribe standards for justification that differ from, or improve upon, our ordinary standards. I merely try to explicate the ordinary standards, which are, I believe, quite different from those of many classical, (...) e. g., ‘Cartesian’, accounts. (shrink)

A central issue in epistemology concerns the connection between truth and justification. The burden of our paper is to explain this connection. Reliabilism, defended by Goldman, assumes that the connection is one of reliability. We argue that this assumption is too strong. We argue that foundational theories, such as those articulated by Pollock and Chisholm fail to elucidate the connection. We consider the potentiality of coherence theories to explain the truth connection by means of higher level convictions about probabilities, which (...) we call doxastic ascent, and defend such a theory. Our defense appeals to the work of Reid and contemporary cognitive psychology in order to account for the psychological reality of higher level evaluations. (shrink)

Disjunctivism is the view that perceptual experience is either constituted by fact in the world or mere appearance. This view is said to be able to guarantee our cognitive contact with the world, and thus remove a crucial “prop” upon which skepticism depends. This paper has two aims. First, it aims to show that disjunctivism is a solution to Cartesian skepticism. Cartesian skepticism is an epistemological thesis, not an ontological one. Therefore, if there is an external world, we may well (...) undergo a veridical experience, and thus we can take advantage of disjunctivism to adopt an anti-evidential-skepticism strategy to counter Cartesian skepticism. Second, this paper argues that disjunctivism fails to solve Pyrrhonian skepticism. To counter Pyrrhonian skepticism, one has to give reasons both for his belief and for his believing. But disjunctivism can only account the former, that is, the reason for the content of perceptual belief. Given that one’s experience in good case and bad case is subjectively indistinguishable, one cannot just use his experience to justify his believing. This shows that disjunctivism cannot meet the requirement to provide an adequate account for reflective knowledge. (shrink)

There is a view abroad on which perceptual experience has representational content in this sense: in it something is represented to the perceiver as so. On the view, a perceptual experience has a face value at which it may be taken, or which may be rejected. This paper argues that that view is mistaken: there is nothing in perceptual experience which makes it so that in it anything is represented as so. In that sense, the senses are silent, or, in (...) Austin's term, dumb. Perceptual experience is not as such either veridical or delusive. It may mislead, but it does not take representation to accomplish that. (shrink)

What modal relation must a fact bear to a belief in order for this belief to constitute knowledge of that fact? Externalists have proposed various answers, including some that combine externalism with contextualism. We shall find that various forms of externalism share a modal conception of “sensitivity” open to serious objections. Fortunately, the undeniable intuitive attractiveness of this conception can be explained through an easily confused but far preferable notion of “safety.” The denouement of our reflections, finally, will be to (...) show how replacing sensitivity with safety makes it possible to defend plain Moorean common sense against the spurious advantages over it claimed by skeptical, tracking, relevant-alternative, and contextualist accounts.

Ernest Sosa's A Virtue Epistemology, Vol. I is arguably the single-most important monograph to be published in analytic epistemology in the last ten years. Sosa, the first in the field to employ the notion of intellectual virtue – in his ground-breaking ‘The Raft and the Pyramid’– is the leading proponent of reliabilist versions of virtue epistemology. In A Virtue Epistemology, he deftly defends an externalist account of animal knowledge as apt belief, argues for a distinction between animal and reflective knowledge, (...) contends that rational intuition is an intellectual virtue ; and offers responses to dream scepticism, the problem of the criterion and the value problem. Nearly all of these arguments are new, albeit consistent with Sosa's earlier work; that is, consistent with two notable exceptions. First, c ontra Sosa's ‘Replies’ in Ernest Sosa and His Critics, A Virtue Epistemology explicitly contends that safety is not required for animal knowledge. Second, unlike Sosa's Knowledge in Perspective, which arguably construes the intellectual virtues as merely instrumentally valuable, A Virtue Epistemology explicitly contends that the intellectual virtues are instrumentally and constitutively valuable. Best read in conjunction with the above monographs and Epistemic Justification, A Virtue Epistemology is mandatory reading for epistemologists and graduate students in the field. It will rightly set the standard for debates in analytic epistemology for years to come.I will summarize and raise objections to two key conclusions that are unique to A Virtue Epistemology: the ‘kaleidoscope-perceiver’ has animal knowledge but lacks reflective knowledge; unlike the k-perceiver, the ordinary perceiver has reflective knowledge. My objections …. (shrink)
