Pragmatic Replies to Skepticism

This essay extends my side of a discussion begun earlier with Duncan Pritchard, the recent author of Epistemic Luck.Pritchard’s work contributes significantly to improving the “diagnostic appeal” of a neo-Moorean philosophical response to radical scepticism. While agreeing with Pritchard in many respects, the paper questions the need for his concession to the sceptic that the neo-Moorean is capable at best of recovering “‘brute’ externalist knowledge”. The paper discusses and directly responds to a dilemma that Pritchard poses for virtue epistemologies (VE). (...) It also takes issue with Pritchard’s “merely safety-based” alternative. Ultimately, however, the criticisms made here of Pritchard’s dilemma and its underlying contrast of “anti-luck” and “virtue” epistemologies are intended to help realize his own aspirations for a better diagnosis of radical scepticism to inform a still better neo-Moorean response.

In this paper I examine a series of criticisms that have been levelled against Quine's naturalized epistemology, regarding its response to the problem of scepticism. Barry Stroud and Michael Williams, assuming that Quine wishes to refute scepticism, argue that Quine not only fails to undertake this refutation, but is also committed to theses (such as the inscrutability of reference and the underdetermination of theory by evidence) which imply versions of scepticism of their own. In Quine's defence, Roger Gibson argues that (...) Quine can succeed in showing sceptical doubts to be incoherent. But I contend that both parties of this dispute wrongly assume that Quine wishes to defeat the sceptic in a traditional way. Instead, Quine is happy to 'acquiesce' in scepticism about a certain kind of justification. No logical justification of our scientific beliefs is possible on his view. But Quine thinks that pragmatic justification is possible, and acknowledging that this is his view leads to the resolution of a number of interpretive quandaries. (shrink)

One of the many philosophical responses to scepticism is naturalism. It is explored how and to what extent it is successful in discussing these questions as they pertain external world scepticism. One interesting feature of naturalism is that it shares with scepticism the view that we lack proof and knowledge of an external world. The naturalist, however, unlike many sceptics and their more traditional disputants, doesn't think it matters. The first part of the paper contains a description of the naturalistic (...) response with emphasis on so-called frame-judgments. The second part is addressed to criticism of this response and replies to it. (shrink)

We offer an overview of what we take to be the main themes in Annalisa Coliva’s book, Moore and Wittgenstein: Scepticism, Certainty and Common Sense. In particular, we focus on the ‘framework reading’ that she offers of Wittgenstein’s On Certainty and its anti-sceptical implications. While broadly agreeing with the proposal that Coliva puts forward on this score, we do suggest one important supplementation to the view—viz., that this way of dealing with radical scepticism needs to be augmented with an account (...) of the meta-sceptical problem which this proposal generates, which we call epistemic vertigo.

This paper examines the role of ?situations? in John Dewey's philosophy of logic. To do this properly it is necessary to contrast Dewey's conception of experience and mentality with views characteristic of modern epistemology. The primary difference is that, rather than treat experience as peripheral and or external to mental functions (reason, etc.), we should treat experience as a field in and as a part of which thinking takes place. Experience in this broad sense subsumes theory and fact, hypothesis and (...) evidence, reason and observation, thought and perception. Logic in this view is a formal study of the generic features of all possible kinds of experience in this broad (thick, deep, wide, multifaceted) sense. The goal of this paper is to explain what Dewey thinks a situation is in the context of this view of experience, and to argue for the fundamental importance of that idea for logic and philosophy in general.

Even though the lines of thought that support skepticism are extremely compelling, we're inclined to look for ways of blocking them because it appears to be an impossible view to accept, both for intellectual and practical reasons. One goal of this paper is to show that when skepticism is packaged right, it has few problematic implications (or at least fewer than is often assumed). It is, for example, compatible with all the following claims (when these are correctly interpreted).

Feminist claims that scientific activity is intimately involved with the oppression of women, often identify aspects of the epistemology of science, or scientific method, as the primary culprit. In my dissertation I try to persuade my feminist colleagues that despite the important gains we have made through the criticism of science, our fairly recent investment in an epistemological critique is yielding diminishing returns. I begin by examining the epistemological reflections of a number of feminist critics of evolutionary biology, including Ruth (...) Hubbard and Ruth Bleier. I then discuss the more general epistemological approaches of Evelyn Fox Keller, Sandra Harding and Helen Longino. ;There are a number of features of feminist epistemology which make it ineffective as a method for adequately addressing the oppression of women by science. For example, feminist epistemological examinations of science have often involved essentialist claims about "women's" experience, and over-general conceptions of science as an institution. These problems are discussed throughout the dissertation. However, the principal focus involves the philosophical details of the feminist epistemologies themselves. Specifically, I focus on their reliance on a questionable model of human psychology, that I refer to as "representationalism." ;My anti-representationalist approach is inspired by the work of two neo-pragamatist philosophers, Richard Rorty and Donald Davidson. For the purposes of this dissertation, representationalism is the view that beliefs are the subjective, representational end-product of a sensory process, in which the objects of our world are sensed and then screened through our subjective perceptual frameworks . My concern is that the representational conception of beliefs as filtered representations of the world makes coherent a global scepticism about the truth of our beliefs. Since, on this model, beliefs do not arise from direct access to the world, then they can be radically wrong. All of our representations might be completely inaccurate because they are filtered through our perceptual apparatus, language, cultural worldview and/or theory allegiance. Following Rorty and Davidson, I argue that epistemological debates are premised on the coherence of global scepticism, and that, due to the nature of the representationalist model on which the debates are based, the battle with global scepticism is futile. ;Surveying feminist contributions to epistemological debates in science, I show how these contributions invite the coherence of scepticism. In the end, each contribution either accepts scepticism, with relativist resignation, or attempts to defeat it with various claims to objectivity. While the latter response has proven futile, for both feminist and traditional epistemologists alike, the former response is equally problematic. Either way, issues of relativism and scepticism can be used against our well-justified claims that women are being harmed by science. ;In the latter half of my dissertation I offer a pragmatic alternative based on Davidson's philosophy of language. Davidson argues that, on a non-representationalist model of language use, global scepticism is not a coherent option. His views undermine the motivation for participating in the epistemological debates that attempt to address scepticism as a coherent and ever-present concern. By undermining the motivation for these philosophical pursuits I hope to encourage my feminist colleagues to return to their important work in science and science criticism with the assurance that our concepts of "error" and "truth" are not always enemies that need feminist epistemological reconfiguration.

Widely acknowledged as the principal architect of Scottish common sense philosophy, Thomas Reid is increasingly recognized today as one of the finest philosophers of the eighteenth century. Combining a sophisticated response to the skeptical and idealist views of his day, Reid's thought stands as an important alternative to Humean skepticism, Kantian idealism and Cartesian rationalism. This volume is the first comprehensive overview of Reid's output and covers not only his philosophy in detail, but also his scientific work and his extensive (...) historical influence. (shrink)

I will discuss those epistemic accounts of truth that say, roughly and at least, that the truth is what all ideally rational people, with maximum evidence, would in the long run come to believe. They have been defended on the grounds that they can solve sceptical problems that traditional accounts cannot surmount, and that they explain the value of truth in ways that traditional (and particularly, minimal) accounts cannot; they have been attacked on the grounds that they collapse into idealism. (...) I show that all these claims are mistaken. The system of statements accepted by an adherent of an epistemic account who also accepts the equivalence scheme is the same as that accepted by an adherent of a traditional account who also accepts a remarkably strong thesis of epistemic optimism. The singling out of one rather than another claim within this system as defining 'true' cannot make as much difference as to imply idealism or refute scepticism. However, it can make all the difference when it is a matter of explaining the value of truth. For a crucial point in such explanation depends on what can be soundly substituted for what in intensional contexts; above all those governed by such verbs as 'know', 'hope', 'believe', 'value'. That is, it depends on what expressions are intensionally equivalent. And one point of singling out one formulation as definitional can be to settle just this. But though some epistemic theorists have deemed ability to explain the value of truth a merit of their account (and lack of this ability a fatal defect of traditional accounts, of minimal accounts in particular), it turns out that minimal accounts of 'true' fit a sound account of our valuing of truth in a way that epistemic accounts do not. In the course of this argument I rebut related positions: e.g. Dummett's, that minimal definitions fail because they cannot account for the point of having a notion of truth, and that an account of the practice of assertion is what would fill this lacuna. I argue to the contrary that if the point of the notion could not be explained on the basis of a traditional definition, it could not be explained at all. (shrink)

I defend, in this paper, a version of a philosophy of common sense. I have use of some things from Reid's account of these matters, others from Wittgenstein's. Scepticism looms large—as do the questions of arguments for and examples of common sense. At least two different notions of common sense emerge, one of which has often been overlooked by philosophers.

Analytic rejections of extreme traditional views, especially scepticism, as 'absurd' in some sense of violating 'rules' of discourse, arc considered. References to linguistic and pragmatic rules are discussed and found inadequate as bases for rejecting scepticism. References to logical principles alone are found to lead into scepticism. The claim that epistemology and scepticism take for granted an inadequate theory of words like 'know', or 'knowledge', as descriptive predicates, is considered. Alternatives, construing such words as appraisive or performative, are discussed, but (...) are not found to provide any real escape from the traditional epistemological issues, or from scepticism.

Philosophers have often thought that concepts such as ”knowledge” and ”truth” are appropriate objects for theoretical investigation. In a discussion which ranges widely over recent analytical philosophy and radical theory, Philosophy and Its Epistemic Neuroses takes issue with this assumption, arguing that such theoreticism is not the solution but the source of traditional problems in epistemology (How can we have knowledge of the world around us? How can we have knowledge of other minds and cultures? How can we have knowledge (...) of ourselves?) and in the philosophy of language (How can we know what our words refer to?).The author draws on Wittgenstein and recent neo-pragmatists (Putnam, Rorty, Davidson, Williams) to argue that analytical philosophy and radical theory alike stand in an ambivalent relationship with skepticism, which issues forth in varieties of ”epistemic neuroses” - manifested most clearly in the cases of metaphysical realism, relativism and causal theories of reference. Each of these projects is defined in terms possibilities that conflict with its own chances of cognitive success. Hymers explains not only the mainstream analytical philosophy of such figures as Devitt, Quine and Burge, but also structuralism (Althusser, Lacan), feminist theory (Seller, MacKinnon, Lugones) and critical theory (Marcuse), in an attempt to outline a therapeutic alternative to philosophical theoreticism.

This paper elucidates the pragmatist elements of Thomas Reid's approach to the justification of first principles by reference to Charles S. Peirce. Peirce argues that first principles are justified by their surviving a process of ‘self-criticism’, in which we come to appreciate that we cannot bring ourselves to doubt these principles, in addition to the foundational role they play in inquiries. The evidence Reid allows first principles bears resemblance to surviving the process of self-criticism. I then argue that this evidence (...) allows Reid and Peirce a way out of the dilemma between dogmatism and skepticism regarding the justification of such principles, insofar as they are epistemically, and not solely practically, justified.

In the first part of my dissertation I defend a fairly sweeping form of skepticism about the external world: For any significantly informative proposition about the external world we have not the slightest justification for thinking it more likely true than its denial. In defending this thesis, I use a version of the evil demon argument, and I argue that a skeptic need only show the logical possibility of the evil demon; he need not make the demon's existence more plausible (...) than the existence of the everyday world. As part of the overall argument for skepticism, I also offer an analysis of knowledge which I think escapes the Gettier Problem. In Part II, I suggest that while beliefs about the external world cannot be justified as likely true they can be justified because of the pragmatic goals they help us attain. I reject the attempt of the classical pragmatists to equate truth with some pragmatic value, thus my form of pragmatic justification can be called 'non-veridical' justification. I then offer a schema of such a theory in which 'survival', 'manipulation of the ostensible external world', and 'satisfying answers' are the central non-veridical values. One result of the preceding is the discovery of new epistemic relationships which an epistemic agent can have with his beliefs. I call one such relationship 'epistemating' which is the relationship an agent has with beliefs that are part of a 'way of viewing the world' which helps him attain the non-veridical values named above. A second epistemic relationship is called 'scientating' which is the relation a scientist has with a theory that forms part of an alternative 'way of viewing the world' that helps a broad range of ordinary people attain the above named non-veridical values.

The Reason Why by Edo Pivčević is an unconventional philosophy book. The author takes the wind out of the sails of the sceptic’s argument by removing its basis. It is neither epistemology nor ontology; nor does its outcome fall into the usual categories vis à vis the real, including pragmatism. A complete system is developed through a profound examination of explanation, contrasting the conceptual approach with the unbounded naturalistic kind and its dangers, illuminating examples of the latter kind with misunderstandings (...) and abuses in physics, mathematics and computer science; effectively demonstrating the confusions engenderedby varieties of reductionism. The author erects a rational structure of components which are mutually dependent and self-sustaining through the analysis and endorsement of common dualisms, e.g. necessary and contingent truth, self and the world; while distancing causality and determinism.

Can we show that our senses are reliable sources of information about the world? To show this, we need to establish that most of our perceptual judgments have been true. But we cannot determine these inductive instances without relying upon sense perception. Thus, it seems, we cannot establish the reliability of sense perception by means of an argument without falling into epistemic circularity. In this paper, I argue that this consequence is not an epistemological disaster. For this purpose, I defend (...) a normative claim that it is reasonable to accept the general reliability of our perceptual judgments, instead of a factual claim that our perceptual judgments are generally reliable. More specifically, I offer a normative practical argument which explains why it is reasonable to accept the general reliability of our perceptual judgments, even though we cannot establish the general reliability of our perceptual judgments by means of theoretical reasoning.

The paper argues that the relation between the philosophy of common sense and skepticism ought to be perceived of as the relation between the two horns of a dilemma. Each position, it is therefore said, is able to confront the other with a valid objection, something which implies that neither of the two positions are defensible as such. The dilemma is only resolved, it is argued, by the way in which a pragmatic approach to knowledge enables us to incorporate the (...) insights of both common sense and skepticism in a single position.

Even though the philosophy of common sense is not justifi able as such, the assump- tion upon which it rests, namely that there are things which we are not in position to doubt is correct. The reason why Thomas Reid was unable to bring this assumption out in a justifi able manner is that his views, both on knowledge and nature, are to be considered dogmatic. American pragmatists such as Charles Sanders Peirce and John Dewey on the other hand, may (...) be seen as offering us a ‘critical’ and post-Darwinian philosophy of common sense. (shrink)

Philosophical method is itself a branch of philosophy, and does not simply take philosophy as its object. An anti-foundationalist conception of philosophical method can thus be "bootstrapped." The dissertation examines different areas of philosophy which concern inquiry: e.g. , its nature , its object , its medium , finding a pattern of anti-foundationalist argument which extends without paradox to philosophical inquiry and its method. ;The pattern in question has two main aspects. In each context pragmatism occupies a space between two (...) extremes, rejecting their common dualistic premise. For example, without the dualism of subjective and objective, we can see something as partially constituted by our subjectivity without threatening its objectivity. The second main idea is a conception of inquiry as agent-centered. Here pragmatism joins a perspectival conception of objectivity with an infallibilist epistemology, which takes the standard of judgment in a context to be the whole of an inquirer's settled belief. ;In semantics, Donald Davidson criticizes a dualism of conceptual scheme and empirical content, and realigns the Quinean picture of interpretation to refer, in addition to speaker and interpreter, not to sensory stimulation, but to the external, public objects which cause it. This avoids both externalism and Cartesian internalism. Yet in regarding the relation between mind and world as merely causal, he spurns truth as a goal in inquiry. Pragmatists counter that we may reject the dualism while still trying to get the world right. ;Pragmatist metaphysics stands between realism and antirealism. Like Kant, pragmatists reject the Cartesian aim of absolute objectivity, which leads directly to skepticism, while also defending an "empirical realism" opposed to idealism. However, there is another form of skeptical threat opposed to the Cartesian variety. Instead of seeking secure foundations, neo-Pyrrhonian skeptics abandon theoretical understanding of our practices; but when we see knowledge as a standard in inquiry, resulting from critical engagement with the world's causal impacts, we see it as beyond skeptical doubt of any kind. Neo-Pyrrhonists appeal to Wittgenstein's conception of philosophy, but the pragmatist reading places Wittgenstein between "constructive" philosophy and a quietism which sees philosophy as essentially self-undermining.

Edo Pivčević's The Reason Why is a thoroughly admirable book: absolutely straightforward and simple in argument, charmingly written, uncompromisingly legible but widely and tactfully informed, bent on asking and answering a single fundamental question usually cast as "metaphysical" or (after Kant) "epistemological", but, in Pivčević's hands, skillfully turned in what must be called a "pragmatist" direction. Careful readers may find (as I do) that the general lines of the argument are notably congruent with some of Charles Peirce's earliest accounts of (...) the pragmatist treatment of "belief" or "believing-true" meant to displace the entire strategy of "proofs of truth" in the "metaphysical sense of proof" (24) that have been stalemated by the "skeptic's" countermeasures.

This article formulates the grounds on which a pragmatist theory of knowledge may be favored against skepticism and foundationalism without requiring the refutation of skepticism. It explores in considerable detail some of the central positions bearing on the issue, Including views of g e moore, Bertrand russell, Roderick chisholm, Keith lehrer, Leonard nelson. It also provides a fresh characterization of pragmatism and shows the bearing of theories of truth on the justification of knowledge claims.

This article examines how Modern theories of mind remain even in some materialistic and hence ontologically anti-dualistic views; and shows how Dewey, anticipating Merleau-Ponty and 4E cognitive scientists, repudiates these theories. Throughout I place Dewey’s thought in the context of scientific inquiry, both recent and historical and including the cognitive as well as traditional sciences; and I show how he incorporated sciences of his day into his thought, while also anticipating enactive cognitive science. While emphasizing Dewey’s continued relevance, my main (...) goal is to show how his scientifically informed account of perception and cognition combats skepticism propagated by certain scientific visions, exacerbated by commonplace notions about mind, that jointly suggest that human beings lack genuine access to reality.

Coping with everyday life limits the extent of one’s scepticism. It is practically impossible to doubt the existence of the things with which one is immediately engaged and interacting. To doubt that, say, a door exists, is to step back from merely using the door (opening it) and to reflect on it in a detached, theoretical way. It is impossible to simultaneously act and live immersed in situation S while doubting that one is in S. Sceptical doubts—such as ‘Is this (...) really a door?’, ‘Am I really walking?’ — require a reflective withdrawal in thought from the situation at hand. Maintaining sceptical doubt while coping with everyday life requires a split consciousness, a bad faith, with one part of consciousness doubting the existing of things that the other part takes forgranted. For this reason, a sustained lived sceptical doubt is sometimes thought to be impossible. -/- In this article, I examine Wittgenstein's response to scepticism in "On Certainty". I argue that one of his responses is "the response based on action", which is (as other Wittgenstein interpreters have noted) a characteristically pragmatist response. I then evaluate the quality of this pragmatist response to scepticism, noting that actions just as much as representations are susceptible to mis-interpretation. It is argued that despite the insights contained in it, Wittgenstein's contextualism about meaning is inadequate to rescue the Wittgensteinian response to scepticism. (shrink)

Although a huge range of definitions has accumulated in the philosophy, biology and psychology literatures, no consensus has been reached on exactly what innateness amounts to. This has helped fuel an increasing skepticism, one that views the concept as anachronistic and actually harmful to science. Yet it remains central to many life sciences, and to several public policy issues too. So it is correspondingly urgent that its philosophical underpinnings be properly cleaned up. In this paper, I present a new approach (...) that endorses a role in science for innateness while also accommodating many of the skeptical concerns. The key to squaring the circle is to import influential recent work on causal explanation. My thesis is that ascriptions of innateness are best seen as explanatory claims. The account that results has three main original features: 1) Innateness is a pragmatic, relational concept. Every trait may be either innate or non-innate, depending on explanatory context. 2) There is an important distinction between innate traits and innate dispositions. 3) Innateness is useful to science as a higher-level predicate that licenses interventions. It is thereby also clarified what ascriptions of innateness do not tell us. (shrink)

Pragmatist responses to radical skepticism do not receive much attention in contemporary analytic epistemology. This observation is my motivation for undertaking a search for a coherent pragmatist reply to radical doubt, one that can compete, in terms of clarity and sophistication, with the currently most popular approaches, such as contextualism and relevant alternatives theory. As my point of departure I take the texts of C. S. Peirce and William James. The Jamesian response is seen to consist in the application of (...) a wager argument to the skeptical issue in analogy with Pascal's wager. The Peircean strategy, on the other hand, is to attempt a direct rejection of one of the skeptic's main premises: that we do not know we are not deceived. I argue that while the Jamesian attempt is ultimately incoherent, Peirce's argument contains the core of a detailed and characteristically "pragmatic" rebuttal of skepticism, one that deserves to be taken seriously in the contemporary debate.

In this essay I consider the role of authorship in balancing epistemological trust and skepticism in e-science. Drawing on studies of the diagnostic practices of doctors in British breast care units and the gate-keeping practices of a Californian publisher of horticultural works, I suggest that conventions of authorial designation have an important role to play in nurturing the skepticism essential for scientific rigor within the framework of epistemological trust that pragmatism and morality require. In so doing I question the assumption (...) of contemporary scholars that scientific works are determinate in fact, while nonetheless supporting the idea of semi-indeterminate authorship as a goal. I then consider the theoretical and practical consequences of that view with an analysis of the Anglo-American legal constraints on attributions of authorship, and the complex of other relevant interests and rights that may require different models of attribution oriented not around authors themselves, but rather their employer, their manager or supervisor, or some pseudonym deemed to be an appropriate organizing mechanism for the works in question.

This paper examines the relevance of Wittgenstein’s On Certainty to the contemporary debate regarding the problem of radical scepticism. In particular, it considers two accounts in the recent literature which have seen in Wittgenstein’s remarks on “hinge propositions” in On Certainty the basis for a primarily epistemological anti-sceptical thesis—viz., the inferential contextualism offered by Michael Williams and the ‘unearned warrant’ thesis defended by Crispin Wright. Both positions are shown to be problematic, both as interpretations of Wittgenstein and as anti-sceptical theses. (...) Indeed, it is argued that on a reading of On Certainty which has Wittgenstein advancing a primarily epistemological thesis, there is in fact strong evidence to suggest that Wittgenstein thought that no epistemic response to the sceptic was available—at best, it seems, only a pragmatic antisceptical thesis is on offer. Such a conclusion is not without import to the present debate regarding radical scepticism, however, since it poses a general challenge for how the sceptical argument is conceived in the contemporary literature.

The radical skeptic argues that I have no knowledge of things I ordinarily claim to know because I have no evidence for or against the possibility of being systematically fed illusions. Recent years have seen a surge of interest in pragmatic responses to skepticism inspired by C. S. Peirce. This essay challenges one such influential response and presents a better Peircean way to refute the skeptic. The account I develop holds that although I do not know whether the skeptical hypothesis (...) is true, I still know things I ordinarily claim to know. Although it will emerge that this reply appears similar to a classic contextualist response to radical skepticism, it avoids two central problems facing that response. (shrink)

Pragmatic responses to skepticism have been overlooked in recent decades. This paper explores one such response by developing a character called the Pragmatic Skeptic. The Pragmatic Skeptic accepts skeptical arguments for the claim that we lack good evidence for our ordinary beliefs, and that they do not constitute knowledge. However, they do not think we should give up our beliefs in light of these skeptical conclusions. Rather, we should retain them, since we have good practical reasons for doing so. This (...) takes the sting out of skepticism: we can be skeptics, of a kind, without thereby succumbing to practical or intellectual disaster. I respond to objections, and compare the position of the Pragmatic Skeptic to views found in the work of (among others) David Hume, William James, David Lewis, Berislav Marusic, and Robert Pasnau.

This paper defends a principle I call Equal Treatment, according to which the rationality of a belief is determined in precisely the same way as the rationality of any other state. For example, if wearing a raincoat is rational just in case doing so maximizes expected value, then believing some proposition P is rational just in case doing so maximizes expected value. This contrasts with the popular view that the rationality of belief is determined by evidential support. It also contrasts (...) with the common idea that in the case of belief, there are two different incommensurable senses of rationality, one of which is distinctively epistemic. I present considerations that favor Equal Treatment over these two alternatives, reply to objections, and criticize some arguments for Evidentialism. I also show how Equal Treatment opens the door to a distinctive kind of response to skepticism. (shrink)
