Many of our beliefs are acquired online. Online epistemic environments are replete with fake news, fake science, fake photographs and videos, and fake people in the form of trolls and social bots. The purpose of this paper is to investigate the threat that such online fakes pose to the acquisition of knowledge. I argue that fakes can interfere with one or more of the truth, belief, and warrant conditions on knowledge. I devote most of my attention to the effects of (...) online fakes on satisfaction of the warrant condition, as these have received comparatively little attention. I consider three accounts of the conditions under which fakes compromise the warrant condition. I argue for the third of these accounts, according to which the propensity of fakes to exist in an environment threatens warrant acquisition in that environment. Finally, I consider some limitations on the epistemic threat of fakes and suggest some strategies by which this threat can be mitigated. (shrink)

Two of the most orthodox ideas in epistemology are fallibilism and purism. According to the fallibilist, one can know that a particular claim is true even though one’s justification for that claim is less than fully conclusive. According to the purist, knowledge does not depend on practical factors. Fallibilism and purism are widely assumed to be compatible; in fact, the combination of these views has been called the ‘ho-hum,’ obvious, traditional view of knowledge. But I will argue that fallibilism and (...) purism are incompatible. The best explanation for fallibilism requires one to reject purism, while maintaining purism should lead one to reject fallibilism. It follows that the orthodox view of knowledge is deeply mistaken.

There is a widespread assumption that ordinary language philosophy was killed off sometime in the 1960s or 70s by a combination of Gricean pragmatics and the rapid development of systematic semantic theory. Contrary to that widespread assumption, however, contemporary versions of ordinary language philosophy are alive and flourishing, but going by various aliases—in particular (some versions of) "contextualism" and (some versions of) "experimental philosophy". And a growing group of contemporary philosophers are explicitly embracing the methods as well as the title (...) of ordinary language philosophy and arguing that it has been unfairly maligned and was never decisively refuted. In this overview, I will outline the main projects and arguments employed by contemporary ordinary language philosophers, and make the case that updated versions of the arguments made by ordinary language philosophers in the middle of the twentieth century are attracting renewed attention.

In his early essay, “Must We Mean What We Say”, Cavell argues that the claims of ordinary language philosophers regarding “what we say when” are not empirical generalizations about a given group of speakers but are rather to be understood as measuring the limits of what counts as a coherent act of thinking and speaking. Cavell’s charge against the skeptic about the external world is that he seeks to think and speak beyond these limits. In this paper I compare Cavell’s (...) response to the skeptic to Davidson’s. Both base their responses on a broadly Kantian approach that appeals to the conditions under which thinking or speaking about objects is possible. On this approach the skeptic isn’t giving a false answer to an intelligible question, but rather, the question to which the skeptic is giving an answer is shown to be in some way unintelligible. But while Davidson’s critique of the skeptic is based on the conditions of ascribing meaning to one’s words, and contents to one’s beliefs, Cavell’s critique is based on the failure of the skeptic to mean the words he uses in the way that he needs. This difference expresses an underlying disagreement about the meaning of “meaning”: for Davidson the world comes into view through the meaning of our words and concepts, through the contents of our beliefs; for Cavell, the world comes into view through the agreement in “criteria” that are a condition of applying words and concepts to the world. This difference illuminates what Cavell calls “the truth of skepticism”: the idea that “my relation to the world and to others in general is not one of knowing”. (shrink)

Descartes’s Evil Demon argument has been the subject of many reconstructions in recent analytic debates. Some have proposed a reconstruction with a principle of Infallibility, others with a principle of Closure of Knowledge, others with more original principles. In this paper, I propose a new reconstruction, which relies on the combination of two principles, namely the Meta-Coherence principle and the principle of Closure of Justification. I argue that the argument construed in this way is the best interpretation of what is (...) really at play in the Evil Demon intuition, and also that this argument is dialectically much stronger than previous reconstructions. If this is right, then the “Closure plus Meta-Coherence” argument is what anti-sceptics should really be attacking. (shrink)

In this paper I will try to defend a quasi-naturalistic interpretation of J.L. Austin’s work. I will rely on P. Kitcher’s 1992 paper “The Naturalists Return” to compile four general criteria by which a philosopher can be called a naturalist. Then I will turn to Austin’s work and examine whether he meets these criteria. I will try to claim that versions of such naturalistic elements can be found in his work.

En este artículo analizo las críticas recientes de Judith Butler al escepticismo cartesiano y al constructivismo posmoderno, para explicar el distanciamiento de Butler respecto de posturas constructivistas y, al mismo tiempo, como un argumento para afirmar la dimensión ética y con pretensión de universalidad de su defensa de las vidas precarias.

Skeptical problems arising for Kant's version of transcendental idealism have been raised from Kant's own time to the present day. By focussing on how such problems originally arose in the wake of Kant's work, and on the first formulations of absolute idealism by Schelling, I argue that the skeptical problems in question ultimately depend on fundamental features of Kant's philosophy of natural science. As a result, Naturphilosophie and the organic conception of nature cannot easily be separated from the deep and (...) insightful response to these problems offered by absolute idealism. (shrink)

In this article, I am intent on rehabilitating Strawson's overall anti-sceptical strategy. First, I focus on his earlier attempt, which ignited the debate about the adequacy of transcendental arguments against the sceptic. I present Stroud's main reservation that Strawson's viewpoint is unworkable because it does not take into consideration the view of the external world upon which the sceptic is based in order to challenge our knowledge claims. I then focus on Strawson's later attempt, which is based upon a Humean-like (...) naturalistic strategy. I show that his naturalism is intractable for two reasons: first because it reproduces the proof structure of transcendental arguments and ends up employing a rational proof to counter rational proofs; and second, because it matches the sceptic's advice that we should live according to our natural inclinations without ever trying to justify our beliefs. In the last section, I claim that it is possible to rehabilitate transcendental arguments as sound anti-sceptical proofs if we argue for the senselessness of the idea of thing in itself completely apart from our powers of conceptualisation.

Contemporary science seems to be caught in a strange predicament. On the one hand, it holds a firm and reasonable commitment to a healthy naturalistic methodology, according to which explanations of natural phenomena should never overstep the limits of the natural itself. On the other hand, contemporary science is also inextricably and now inevitably dependent on ever more complex technologies, especially Information and Communication Technologies, which it exploits as well as fosters. Yet such technologies are increasingly “artificialising” or “denaturalising” the (...) world, human experiences and interactions, as well as what qualifies as real. So the search for the ultimate explanation of the natural seems to rely upon, and promote, the development of the artificial, seen here as an instantiation of the non-natural. In this article, I would like to try and find a way out of this apparently strange predicament. I shall argue that the naturalisation of our knowledge of the world is either philosophically trivial, or mistaken. First, I shall distinguish between different kinds of naturalism. Second, I shall remind the reader that the kinds of naturalism that are justified today need to be protected and supported pragmatically, but they are no longer very interesting conceptually. We know how to win the argument. We just have to keep winning it. Whereas the kind of naturalism that is still interesting today is now in need of revision in order to remain acceptable. Such a kind of naturalism may be revised on the basis of a realistic philosophy of information, according to which knowing is a constructive activity, through which we do not merely represent the phenomena we investigate passively, but create more or less correct informational models of them, proactively and interactively. I shall conclude that the natural is in itself artefactual, and that the information revolution is disclosing a tension not between the natural and the non-natural, but a deeper one between a user’s and a producer’s interpretation of knowledge. The outcome is a philosophical view of knowledge and science in the information age that may be called constructionist and a revival of philosophy as a classic, foundationalist enterprise. (shrink)

In the last decade, some feminist epistemologists have suggested that the global scepticism which results from the Cartesian dream argument is the product of a self‐consciously masculine modern era, whose philosophy gave pride of place to the individual cognizer, disconnected from the object of knowledge, from other knowers, indeed from his own body. Lorraine Code claims that under a conception of a cognizer as an essentially social being, Cartesian scepticism would not arise. I argue that this is false: an argument (...) parallel in structure, and as well supported as the first‐person Cartesian dream argument, could arise in an epistemology which recognizes the social nature of human life and knowledge. Against Code, it is not the first‐personhood of Cartesianism which generates scepticism. A second‐person scepticism could emerge in a socially conscious epistemology. (shrink)

The Duhem-Quine Thesis is the claim that it is impossible to test a scientific hypothesis in isolation because any empirical test requires assuming the truth of one or more auxiliary hypotheses. This is taken by many philosophers, and is assumed here, to support the further thesis that theory choice is underdetermined by empirical evidence. This inquiry is focused strictly on the axiological commitments engendered in solutions to underdetermination, specifically those of Pierre Duhem and W. V. Quine. Duhem resolves underdetermination by (...) appealing to a cluster of virtues called 'good sense', and it has recently been argued by Stump (Stud Hist Philos Biol Biomed Sei, 18(1):149-159,2007) that good sense is a form of virtue epistemology. This paper considers whether Quine, who's philosophy is heavily influenced by the very thesis that led Duhem to the virtues, is also led to a virtue epistemology in the face of underdetermination. Various sources of Quinian epistemic normativity are considered, and it is argued that, in conjunction with other normative commitments, Quine's sectarian solution to underdetermination amounts to a skills based virtue epistemology. The paper also sketches formal features of the novel form of virtue epistemology common to Duhem and Quine that challenges the adequacy of epistemic value truth-monism and blocks any imperialist naturalization of virtue epistemology, as the epistemic virtues are essential to the success of the sciences themselves.

Skeptics try to persuade us of our ignorance with arguments like the following: 1. I don’t know that I am not a handless brain-in-a-vat [BIV]. 2. If I don’t know that I am not a handless BIV, then I don’t know that I have hands. Therefore, 3. I don’t know that I have hands. The BIV argument is valid, its premises are intuitively compelling, and yet, its conclusion strikes us as absurd. Something has to go, but what? Contextualists contend that (...) an adequate solution to the skeptical problem must: (i) retain epistemic closure, (ii) explain the intuitive force of skeptical arguments by explaining why their premises initially seem so compelling, and (iii) account for the truth of our commonsense judgment that we do possess lots of ordinary knowledge. Contextualists maintain that the key to such a solution is recognizing that the semantic standards for ‘knows’ vary from context to context such that in skeptical contexts the skeptic’s premises are true and so is her conclusion; but in ordinary contexts, her conclusion is false and so is her first premise. Despite its initial attractiveness, the contextualist solution comes at a significant cost, for contextualism has many counterintuitive results. After presenting the contextualist solution, I identify a number of these costs. I then offer a noncontextualist solution that meets the adequacy constraint identified above, while avoiding the costs associated with contextualism. Hence, one of the principal reasons offered for adopting a contextualist theory of knowledge–its supposedly unique ability to adequately resolve the skeptical problem – is undermined. (shrink)

This paper defends a conceptualist answer to the question how objects come by their modal properties. It isolates the controversial metaphysical assumptions that are needed to get ontological conceptualism off the ground, outlines the conceptualist answer to the question and shows that conceptualism is not in as bad a shape as some critics have maintained.

Some philosophical positions maintain that some aspect of reality depends on human practices, cognitive attitudes or sentiments. This paper presents a framework for understanding such positions in a way that renders them immune to a number of natural but allegedly devastating objections.

Radical skepticism relies on the hypothesis that one could be completely cut off from the external world. In this paper, I argue that this hypothesis can be rationally motivated by means of a conceivability argument. Subsequently, I submit that this conceivability argument does not furnish a good reason to believe that one could be completely cut off from the external world. To this end, I show that we cannot adequately conceive scenarios that verify the radical skeptical hypothesis. Attempts to do (...) so fall prey to one or another of three pitfalls: they end up incomplete, reveal a deep contradiction or recreate a non-skeptical hypothesis. I use these results to improve upon Pritchard’s recent attempt at undercutting radical skepticism. (shrink)

Review of Penelope Maddy, What Do Philosophers Do? Skepticism and the Practice of Philosophy (Oxford University Press, Oxford, 2017, 248 pp.).

According to epistemological disjunctivism (ED), in paradigmatic cases of perceptual knowledge, a subject, S, has perceptual knowledge that p in virtue of being in possession of reasons for her belief that p which are both factive and reflectively accessible to S. It has been argued that ED is better placed than both knowledge internalism and knowledge externalism to undercut underdetermination-based skepticism. I identify several principles that must be true if ED is to be uniquely placed to attain this goal. After (...) that, I use those principles to formulate a diachronic skeptical argument. This argument yields the counterintuitive conclusion that understanding a global skeptical hypothesis is all it takes for a rational subject to lose all her perceptual knowledge of the world. Next, I show that a popular Austinian move must reject one or another of the principles that underlie ED. I close by delineating a novel strategy that can block the diachronic skeptical argument while preserving all the principles. The key idea is that perceptual knowledge is grounded in primitive, perceptual and recognitional abilities. This view sheds new light on some puzzling features of global skepticism that have been noted by Descartes and Hume, among others. (shrink)

A theory of reasoned knowledge is presented by developing and demonstrating the methodology of a novel skeptical critique designed to extend the epistemological practice of belief justification to an epistemological practice of reason justification. Analyses of the reasoning found in the theorizations of certain seminal philosophers and leading scientists will reveal how the absence of the epistemic justification of reason defaults to the use of an unjustified form of reason that runs the play of an unrecognized and unchecked dialectic between (...) epistemology and science. An alternative form of reason will be logically outlined and tested against the formalized skeptical critique in order for the newly recognized dialectic to be checked over reason with provisional epistemic justification. Zeno’s paradox and Green’s and Sellars’ critique of givenness are employed as argument functionaries of the reasoned knowledge theory. (shrink)

I develop a new version of the ordinary language response to skepticism. My version is based on premises about the practical functions served by our epistemic words. I end by exploring how my argument against skepticism is interestingly non-circular and philosophically valuable.

Cartesian skepticism about epistemic justification (‘skepticism’) is the view that many of our beliefs about the external world – e.g., my current belief that I have hands – aren’t justified. I examine the two most influential arguments for skepticism – the Closure Argument and the Underdetermination Argument – from an evidentialist perspective. For both arguments it is clear which premise the anti-skeptic must deny. The Closure Argument, I argue, is the better argument in that its key premise is weaker than (...) the Underdetermination Argument’s key premise. However, it’s also likely that the motivation for accepting both key premises is exactly the same. So there may be a sense in which both arguments provide exactly the same motivation for skepticism. Then I argue that if I I’m right about what the motivation for accepting the arguments’ key premises is, then neither argument succeeds in providing a good reason to accept skepticism. I conclude by explaining why I think epistemologists are right to expend a lot of time and effort on refuting these arguments, even if neither argument provides any motivation for skepticism.

The Didascalicon of Hugh of St. Victor encourages the study of many disciplines in order for the soul to acquire knowledge that aids in the restoration of human nature. However, according to Hugh's epistemology much of the acquired knowledge depends upon sensory qualities internalized as images which distract the soul and cause it to degenerate from its original unity. This essay explores the tension between Hugh's educational optimism and Hugh's epistemological pessimism. After considering and rejecting two unsuccessful strategies the soul (...) might pursue for avoiding degeneration and distraction, we shall utilize Hugh's non-representational conception of cognition to develop a plausible intellectual strategy. We shall also build upon some of Hugh's remarks about music to sketch a model of self-knowledge as a kind of proportionality in the soul. (shrink)

Kant’s Refutation targets what he calls the problematic idealist. This is understood by the mainstream of Kantian scholarship as the global skeptic that Descartes briefly adumbrated in his first Meditation. The widespread view in the literature is that the fate of the Refutation is tied to its success as an argument against this Cartesian global skepticism. This consensus is what I want to question in this paper. I argue that Kant’s opponent – the problematic idealist – is not the Cartesian (...) global skeptic but rather what I prefer to call here the Cartesian problematic external-world idealist. According to Cartesian global skepticism, we cannot know whether our commonsensical beliefs are true until we rule out that the skeptical hypotheses are false. In contrast, the Cartesian external-world idealist sees as problematic the assumption that the underlying nature of outer things of which we have ideas is mind-independent rather than caused by our own thinking. My aim here is to disentangle Cartesian global skepticism from Cartesian problematic external-word idealism and show that, if measured against global skepticism, Kant’s Refutation is doomed to fail, while against problematic idealism, it is at least a promising argument.

Skeptical invariantism isn’t a popular view about the semantics of knowledge attributions. But what, exactly, is wrong with it? The basic problem is that it seems to run foul of the fact that we know quite a lot of things. I agree that it is a key desideratum for an account of knowledge that it accommodate the fact that we know a lot of things. But what sorts of things should a plausible theory of knowledge say that we know? In (...) this paper I sketch an answer to this question and then apply it to skeptical invariantism. I start by distinguishing between a “radical” skeptical invariantist position (on which the standards for knowing are so high that we rarely if ever satisfy them) and a more “moderate” skeptical invariantist position (on which the standards are very hard, but not impossible, to satisfy). I then argue that, while radical forms of skeptical invariantism are clearly not going to do a good job of satisfying the key desideratum, more moderate forms can do quite well with respect to it. In particular, I argue the version of moderate skeptical invariantism defended by Davide Fassio can plausibly satisfy it. (shrink)

Recent developments of transcendental arguments reflect the struggle to accommodate Stroud’s devastating objection by giving up on failed expectations in providing proof of what the external-world skeptic calls into question: knowledge of the existence of the outside world. Since Strawson's capitulation in 1984, the truth-direct transcendental arguments have given way to modest belief-direct transcendental arguments that concede that truth-direct transcendental arguments are doomed to fail to establish ambitious conclusions about reality but at the same time hold that they can nonetheless (...) successfully establish modest conceptual connection between the major beliefs within our conceptual scheme. This article seeks the “reactionary” rehabilitation of the old hubris: a new defense of the truth-direct transcendental argument. I set forth a new reconstruction of Kant’s Refutation as a successful truth-directed transcendental argument that meets Stroud’s objection. As with several papers and books about the theme, this article is of a systematic and a historical nature by connecting the contemporary debate about transcendental argument with Kant’s philosophy.

Kant was never satisfied with the version of his “Refu- tation” published in 1787 (KrV, B 275-279). His dissatisfaction is already evident in the footnote added to the preface of the second edition of the Critique in 1787. As a matter of fact, Kant continued to rework his argument for at least six years after 1787. The main exegetical problem is to figure out who is the target of the “Refutation”: a non-skeptic idealist, a global skeptic of Cartesian provenance or (...) both. In this last case, the related problem is to know whether either of them is the Cartesian skeptic of the first Meditation, the idealist skeptic of the second Meditation and first part of the third Meditation, or some other non-skeptic idealist. I present and defend a new reconstruction of Kant’s “Refu- tation” as a successful argument against Mendelssohnian idealism of Cartesian provenance. This defense is based on a simple logical sketch of the proof provided by Dicker but essentially modified in light of Dyck’s insight about Kant’s opponent. How shall I support my reading? First, by appealing to overwhelming textual evidence according to which the proof is of the existence of mind-independent things, showing that Kant’s main opponent is Mendelssohn’s idealism of Cartesian provenance. Finally, I support my reading by showing that Kant’s “Refutation” is doomed to fail against all forms of global skepticism but is quite successful against Mendelssohn’s idealism. (shrink)

I argue that my non-dual epistemic-phenomenalist view is the one that best harmonises my interpretation of the Fourth Paralogism with the widely shared reading of the Refutation of Idealism that I sketched and defended above. The bottom line of my view is a clear distinction between the metaphysical and epistemological sides of Kantian idealism. Again, according to my non-dual-epistemic-phenomenalism, the mundus sensibilis and mundus intelligibilis are epistemologically distinct ways of considering the metaphysically identical outside world. Appearances are nothing but the (...) way the things in themselves appear or exist inside our sensible minds as mere representations. In this sense, I reject both the two-world view, the two-aspect view, and Allais’s deflationary anti- phenomenalist reading. (shrink)

The aim of this paper is to present a novel reading of Kantian idealism. In want of a better name, I call my interpretation “one-object-plus-epistemic phenomenalism”. I partially endorse Allison’s celebrated position, namely his rejection of metaphysical world-dualism. Yet, I reject Allison’s deflationary two-aspect view. I argue that Kantian idealism is also metaphysically committed to an ontological noumenalism (one-object), namely the claim that the ultimate nature of reality is made up of unknown things in themselves (substantia noumena). Natural sciences can (...) only reveal the relational/structural properties of things as they appear rather than the intrinsic properties of substantia noumena in the negative sense. My anti-deflationary reading is similar to Allais’s, and my agnostic monism to Hanna’s. However, against both, I hold that appearances are not the accusative objects of our sensible representations, but rather, as Kant repeatedly states: “mere representations”. The accusative objects of our senses are substantia noumena in the negative sense. Moreover, my view is also similar to Langton’s. Again, against Langton, I hold that appearances are not merely relational properties of substantia noumena but the way that such substantia noumena exist inside our mind as “mere representations”. In this regard, I also partially endorse Guyer’s and Van Cleve’s phenomenalist reading because these substantia noumena in the negative sense can only be cognized mind-dependently, namely as appearances. However, against Guyer and Van Cleve, I hold that the phenomenalist side of Kantian idealism is purely epistemological rather than ontological: what Kant calls the necessary unity of representations according to categories is not a logical construction of objects out of representations, that is, an ontological reduction of noumena to appearances, but rather the way we sense-independently cognize mind-independent noumena.

From time to time philosophers and scientists have made sensational, provocative claims that certain things do not exist or never happen that, in everyday life, we unquestioningly take for granted as existing or happening. These claims have included denying the existence of matter, space, time, the self, free will, and other sturdy and basic elements of our common-sense or naïve world-view. Around the middle of the twentieth century an argument was developed that can be used to challenge many such skeptical (...) claims based on linguistic considerations, which came to be known as the Paradigm Case Argument ...

My focus here will be Rudolf Carnap’s views on ontology, as these are presented in the seminal “Empiricism, Semantics and Ontology” (1950). I will first describe how I think Carnap’s distinction between external and internal questions is best understood. Then I will turn to broader issues regarding Carnap’s views on ontology. With certain reservations, I will ascribe to Carnap an ontological pluralist position roughly similar to the positions of Eli Hirsch and the later Hilary Putnam. Then I turn to some (...) interrelated arguments against the pluralist view. The arguments are not demonstrative. Some possible escape routes for the pluralist are outlined. But I think the arguments constitute a formidable challenge. There should be serious doubt as to whether the pluralist view, as it emerges after discussion of these arguments, will be worth defending. Moreover, there is an alternative ontological view which equally well subserves the motivations underlying ontological pluralism. (shrink)

The main aim of this paper is to investigate what becomes of normativity in naturalistic epistemologies. What particular stand a given naturalistic epistemology takes on normativity will depend both on what it thinks is wrong with traditional epistemology and on what level of normativity is at stake. I propose a tentative typology of possible attitudes towards normativity from within naturalistic epistemology. In section I, I give a brief presentation of traditional epistemology, stressing the dimensions of this approach that may appear (...) problematic to naturalists. In section II, I present and discuss the naturalist project in its radical form, as personified by Quine, who questions not only the way in which traditional epistemology proceeds in order to attain its objectives, but also the validity of these objectives. The last two sections concentrate on more moderate versions of naturalism. Section III investigates the various possible roles that may be assigned to psychology in these moderate forms of naturalism and the ensuingconsequences vis-a-vis the problem of normativity. In section IV, I distinguish between two levels of normativity in epistemology, what I call the normativity of means and the normativity of ends and I discuss the prospects of a naturalization of epistemic ends.

Is ruling out the possibility that one is dreaming a requirement for a knowledge claim? In “Philosophical Scepticism and Everyday Life” (1984), Barry Stroud defends that it is. In “Others Minds” (1970), John Austin says it is not. In his defense, Stroud appeals to a conception of objectivity deeply rooted in us and with which our concept of knowledge is intertwined. Austin appeals to a detailed account of our scientific and everyday practices of knowledge attribution. Stroud responds that what Austin (...) says about those practices is correct in relation to the appropriateness of making knowledge claims, but that the skeptic is interested in the truth of those claims. In this paper, we argue that Stroud’s defense of the alleged requirement smuggles in a commitment to a kind of internalism, which asserts that the perceptual justification available to us can be characterized independently of the circumstances in which we find ourselves. In our reading of Austin, especially of Sense & Sensibilia, he rejects that kind of internalism by an implicit commitment to what is called today a “disjunctive” view of perception. Austin says that objectivity is an aspect of knowledge, and his disjunctivism is part of an explanation of why the alleged requirement is not necessary for a knowledge claim. Since both Stroud and Austin are committed to the objectivity of knowledge, Stroud may ask which view of perceptual knowledge is correct, whether the internalist or the disjunctive. We argue that by paying closer attention to what Austin says about our practices of knowledge attribution, one can see more clearly that it is grounded not only on a conception of objectivity, but also on a conception of ourselves as information agents, a conception that is as deeply rooted as that of the objectivity of knowledge. This gives us moral and practical reasons to favor the disjunctive view of perception. (shrink)

This chapter considers the encounter of skepticism with the Kantian and post-Kantian philosophical enterprise and focuses on the intriguing feature whereby it is assimilated into this enterprise. In this period, skepticism becomes interchangeable with its other, which helps understand the proliferation of many kinds of views under its name and which forms the background for transforming skepticism into an anonymous, routine practice of raising objections and counter-objections to one’s own view. German philosophers of this era counterpose skepticism to dogmatism and (...) criticism, ancient to modern skepticism, and, importantly, conceptualize the transitions from one form to another, which forms the conceptual matrix in which new disciplinary forms, such as psychology, anthropology, and historicism contend for cultural-intellectual standing beside philosophy. I present this assimilationist trajectory by reviewing three well-known moments of this encounter of skepticism and idealism: (1) Kant’s idealization of skepticism as a floating position amidst various philosophical positions through the dialectic, polemics, systematics, and history of pure reason; (2) Fichte’s schematic conception of skepticism as a dispute of systems in the early Wissenschaftslehre following his review of the skeptic G. E. Schulze’s attacks on Critical philosophy; (3) Hegel’s historicizing conception of skepticism in the context of differences between subjective idealism and speculative thought and his early Jena review of another work by the same skeptic Schulze.

Thesis (Ph. D.)--University of Hawaii at Manoa, 1991.

This is an updated version of an essay originally written for a special issue of Philosophical Topics on the links between Kant and analytic philosophy. It explores these links by focusing on: Wittgenstein’s Tractatus; the logical positivism endorsed by Ayer; and the (very different) variation on that theme endorsed by Quine. The claim defended is that in all three cases we see analytic philosophers trying to attain and express a general philosophical understanding of why the bounds of sense should be (...) drawn where they should—but thereby confronting the aporia, which Kant too confronted, that it is impossible to do this without transgressing those very bounds. The paper closes by suggesting that the problem is in trying to attain and express such an understanding; in other words, that such an understanding is attainable, but not expressible. (shrink)

The epistemological problem of the external world asks: (1) “How is knowledge of the external world possible given certain obstacles which make it look impossible?” This is a “how-possible?” question: it asks how something is possible given certain obstacles which make it look impossible (cf. Cassam 2007; Nozick 1981; Stroud 1984). Now consider the following question, which asks: (2) “How is a philosophically satisfying answer to (1) possible?” Skepticism is the thesis that knowledge of the external world is impossible. It (...) therefore represents a negative answer to the first question. Meta-epistemological skepticism is the thesis that a satisfying philosophical explanation of how our knowledge of the external world is possible is itself impossible. It therefore represents a negative answer to the second question. In this thesis, I explore the prospects of meta-epistemological skepticism. In particular, I structure the thesis around two master arguments from for meta-epistemological skepticism. The first argument is that skepticism represents a kind of paradox which requires dispensing with a plausible principle or belief, or even 'platitude', which means that there's no philosophically satisfying response to the paradox (see, e.g., Stroud 1984), and the second argument is “Stroud’s dilemma” (cf. Cassam 2009), that either we explain how external world knowledge is possible by reference to what external world knowledge we have, thereby failing to answer the philosophical question adequately, or else we don't, but then we succumb to first-order skepticism. I argue that the first argument fails to provide adequate support for meta-epistemological skepticism. However, the second argument, Stroud’s dilemma, is plausible and withstands serious objections (e.g., from Sosa 1994, Williams 1996, and Cassam 2009). In short, while the worry emerging out of the 'skeptical paradox' view fails to adequately support meta-epistemological skepticism, Stroud’s dilemma succeeds. Fortunately, it doesn't show that we lack external world knowledge; we rather just can't explain, philosophically, how it's possible. We may have first-order knowledge without understanding how it's possible. This thesis therefore represents a partial defense of meta-epistemological skepticism. Meta-epistemological skepticism is a live option in epistemology. (shrink)

This thesis is, in part, a defence of a broad-based approach to epistemology. We should be wary of taking too narrow a focus and thus neglecting important aspects of knowledge. If we are too focused on one methodology then we are likely to miss insights that can come about from a different perspective. With this in mind, I investigate two particular methodologies in detail: Kornblith’s naturalism and Craig’s ‘genealogical’ approach. Kornblith emphasises the importance of looking at knowledge in the context (...) of the natural world, thus stressing the continuity between animal and human knowledge. Craig, on the other hand, focuses on a distinctly human aspect of knowledge: the importance of enquiry and the sharing of information. As such, the two theories of knowledge that are developed have different emphases. I argue that by bringing them together we can better understand what knowledge is. This leads us to the other main contribution of this thesis, which is a defence of the role of reflection in epistemology. This has often been neglected in contemporary epistemology, primarily because of the effectiveness of externalist theories of knowledge. The focus on externalism has lead to reflection being sidelined. I do not argue that reflection is necessary for knowledge, but rather want to bring back attention to the important role that it plays in human life. Reflectively accessible justification is necessary for our knowledge claims and therefore plays a vital role in enquiry. If we add reflectively accessible justification to knowledge then it is both more stable and more valuable. Even if it is not necessary for knowledge, reflection should not be neglected. (shrink)

In questo articolo parlo della influenza di Einstein su Wittgenstein a partire da alcuni problemi che si pongono all’olismo. L’olismo è stato spesso collegato a Wittgenstein, almeno in forma di “olismo locale”. L’olismo è però soggetto a due tipi di paradossi: il paradosso della comunicazione per l’olismo semantico e il paradosso del relativismo concettuale per l’olismo epistemologico. Dopo aver presentato brevemente i due paradossi, confronto le risposte di Davidson, in difesa dell’olismo, con quelle di Wittgenstein (o di tipo wittgensteiniano). Da (...) questo confronto nasce un problema nell’interpretazione di Wittgenstein. Infatti, dalle sue risposte ai due paradossi emerge una tensione nella sua visione dei giochi linguistici e in particolare nei suoi esperimenti mentali, che sono stati tradizionalmente interpretati in modi contrapposti. La mia proposta è che una rilettura di alcune riflessioni di Wittgenstein su Einstein e la relatività può aiutare a cogliere meglio il significato di questa tensione. (shrink)

 ’ The Significance of Philosophical Scepticism has been widely read and discussed by philosophers who are interested in skepticism about our knowledge of the external world.1 Some of his later writings on the topic (such as Stroud (1989) and (1994)) are considered essential reading too. This does not, however, mean that what Stroud says about skepticism2 has as much impact on the discussion of skepticism as it deserves. It seems that his insights into the nature of skepticism have been (...) largely misunderstood or missed. Although Stroud has never argued for skepticism or claimed that skepticism is true, he has been ” ( 2001 37)  The Significance of Philosophical Scepticism is, as the title says so clearly, that skepticism is philosophically significant and should be considered seriously, but skepticism is still felt by most philosophers.

There is a well-known line of thought, associated with Donald Davidson, that connects the notion of a perceptual given—of non-linguistic or non-conceptual experience of the world—with skepticism. Against this, I argue that the notion of what is given in perception leads to skepticism only on certain interpretations. I argue, in fact, that there must be perceptual experience such that there is “something it is like” to have it, or that would provide the subject of a phenomenological analysis, if we are (...) to block skepticism in its most radical forms. In particular, I claim that there is a distinctive phenomenology of the experience of agency. These phenomenological claims are conclusions of a transcendental argument according to which our having such experience is a condition of our having a meaningful language. Moreover, the same transcendental argument is sufficient to show the incoherence of radical skepticism about the external world. And I argue that the proper understanding of perceptual experience—as object involving—renders the standard objections to transcendental arguments ineffective. (shrink)
