The paper argues that in the Critique of Pure Reason Kant develops two anti-sceptical strategies. In the Fourth Paralogism (CPR A) he believes himself able to refute the sceptic by demonstrating that external perception is immediate. This strategy is rather unconvincing. In the Refutation of Idealism (CPR B) Kant promotes the material dependence of inner sense on outer sense. I show that Kant’s argument for material dependence has been widely overlooked, even though it is the strongest argument against external (...) world scepticism he develops, since it anticipates mental content externalism while preserving transcendental idealism and empirical realism.

Despite Donald Davidson's influential criticism of the very notion of conceptual schemes, the notion continues enjoying its popularity in contemporary philosophy and, accordingly, conceptual relativism is still very much alive. There is one major reason responsible for Davidson's failure which has not been widely recognized: What Davidson attacks fiercely is not the very notion, but a notion of conceptual schemes, namely, the Quinean notion of conceptual schemes and its underlying Kantian scheme-content dualism. However, such a notion simply cannot carry the (...) weight of conceptual relativism for it does not catch the essences of conceptual relativism. Consequently, I argue that the very notion of conceptual schemes and conceptual relativism have survived Davidson's attack. Therefore, the failure of the Quinean notion of conceptual schemes and Kantian scheme-content dualism, even if Davidson can claim victory, does not mark the end of the very notion of conceptual schemes.[ABSTRACT FROM AUTHOR].

Interpreters of Kant’s Refutation of Idealism face a dilemma: it seems to either beg the question against the Cartesian sceptic or else offer a disappointingly Berkeleyan conclusion. In this article I offer an interpretation of the Refutation on which it does not beg the question against the Cartesian sceptic. After defending a principle about question-begging, I identify four premises concerning our representations that there are textual reasons to think Kant might be implicitly assuming. Using those assumptions, I offer (...) a reconstruction of Kant’s Refutation that avoids the interpretative dilemma, though difficult questions about the argument remain. (shrink)

John. R. Searle’s account of perception is often called the intentionality theory of perception (ITP). ITP maintains direct realism. According to direct realism, physical objects are directly perceived. Searle denies Locke's representational theory of perception since the latter is an antithesis of direct realism. Searle's contention is that, first, according to the representational theory of perception, subjective ideas (mind-dependent entities) are the only object of perception, we do not perceive physical objects at all. Second, Searle says that on the face (...) of the resemblance thesis, the representational theory of perception is not secured because the former is insufficient to explain the latter. This paper is an attempt to reflect on these two charges raised by Searle. First, I will try to show how we can conceive physical objects are objects (indirect) of perception within Locke’s representational theory of perception. Then, it will be argued that Locke’s representationalist theory of perception can be upheld without the support of the resemblance thesis. (shrink)

On the basis of Nāgārjuna’s works, especially the Mūlamadhyamakakārikā, this paper proposes a sceptic presupposition as the departure point of Nāgārjuna’s refutations. This presupposition invalidates perceptual knowledge, and thus the identities of existents can only be deemed as referents assumed by concepts. Then the “confinement principle,” a theorem tacitly applied in Nāgārjuna’s arguments, is justified, i.e., any definition or description of a concept would necessarily confine its assumed referent to an invariable and isolated state. This principle enables Nāgārjuna to deduce (...) contradictions between the static and isolated nature of the assumed referent, and the activity in which it must be involved. Notions of both a static identity and its activity are deep-rooted in all referential mental activities of sentient beings. Hence all concepts are found to be self-contradictory and therefore devoid of referents, namely, empty. Thus, Nāgārjuna is refuting the whole intelligible world, and his position can be identified as epistemological nihilism—nothing within our ken can possibly be. (shrink)

In Seeing Things as They Are (Searle 2015), Searle developed a direct realist’s theory of perception. According to direct realism, physical objects are directly and immediately perceived. Searle claims that Berkeley’s theory of perception goes against direct realism. For Searle, Berkeley’s theory suggests that only subjective experiences (ideas) are directly and immediately perceived, not physical objects. Contrary to Searle, G. S. Pappas claims that Berkeley’s theory of perception is consistent with the view that physical objects are immediately perceivable (Pappas 1982; (...) Pappas 1987). Given the conflicting interpretations of Berkeley’s theory of perception, this paper attempts to defend Searle’s position on Berkeley’s theory of perception. It refutes Pappas’ interpretation by arguing that he is inconsistent with Berkeley’s theses of ontological phenomenalism and heterogeneity thesis. (shrink)

Hegel’s Science of Logic is widely acknowledged as one of the greatest works of European philosophy. However, its contribution to arguably the most important philosophical problem, Pyrrhonian scepticism, has never been examined in any detail. Pyrrhonian Scepticism and Hegel's Theory of Judgement fills a great lacuna in Hegel scholarship by convincingly proving that the dialectic of the judgement in Hegel’s Science of Logic successfully refutes this kind of scepticism. Although Ioannis Trisokkas has written the book primarily for (...) those students of philosophy who already have an interest in Hegel’s epistemology and philosophy of language and/or his Science of Logic, it will also appeal to those who investigate the problem of scepticism independently of the Hegel corpus.

This chapter analyzes two short texts in which Peirce sketches out an anti-skeptical argument inspired by Kant’s refutation of idealism. The chapter will first consider why Peirce found Kant’s argument interesting and promising, given that it is often regarded as problematic and unsuccessful. It will then briefly reconstruct Kant’s refutation, highlighting its most problematic passages. Moreover, since Peirce’s own version of the argument relies on Kant’s views regarding the temporal structure of consciousness, the chapter will explain how Peirce (...) tackles this issue in “The Law of Mind.” Finally, the chapter considers Peirce’s own anti-skeptical argument and examines whether and how it can be seen as appropriating Kant’s strategy.

Bub's criticism of Bell's locality postulate is discussed. The locality postulate is explained, and it is shown that Bub is in fact arguing against a class of theories which are subject to stronger restrictions than this postulate, and therefore his “refutation” of the latter is misleading.

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)

This paper comments Susan Haack’s remarks about Twardowski’s criticism of relativism in the theory of truth. The author summarizes Twardowski’s arguments for truth-absolutism and tries to show that that their presentation by Haack is incomplete. The defense of Twardowski’s position in the paper uses ideas developed by Tarski and Kokoszyñska.

This paper examines Hume’s understanding of a third doxastic position distinct from belief and disbelief, arguing that his epistemology presupposes different forms of doxastic neutrality. While Hume does not explicitly discuss this third position, his Treatise of Human Nature and Enquiry concerning Human Understanding offer ideas relevant to contemporary debates on suspension of judgement and inquiry. Hume engaged with Pyrrhonian scepticism, finding its suspension of judgement excessive, yet acknowledging that the Pyrrhonian arguments are theoretically difficult to refute. Based on (...) various interpretations of Hume’s critique of Pyrrhonian ideas, we discuss the relevance of his thoughts on suspension of judgement and inquiry through the lens of modern epistemological discussions.

In a previous article, Professor abelson contended that the mind-Body identity theory was 'mathematically impossible' inasmuch as the number of possible mental states of a finite thinking organism are infinite, While the number of possible bodily states of such an organism are necessarily finite. I argue that this refutation does not succeed because although it is true that a finite brain can have only a finite number of brain states, Abelson had not demonstrated that there was a limitation on (...) what type of brain state could be generated by a finite brain. Thus, For instance, Although the number of natural numbers that such a brain could think of was necessarily finite, This in itself did not militate against the possibility of the brain producing a brain state corresponding to any natural number, Out of a possible infinite set, That can be thought of.

In 1931–1934 Kazimierz Ajdukiewicz formulated two versions of the theory of meaning (A1 and A2). Tarski showed that A2 allows synonymous names to exist with different denotations. Tarski and Ajdukiewicz found that this feature disparages the theory. The force of Tarski’s argument rests on the assumption that none of adequate theories of meaning allow synonymous names to exist with different denotations. In the first part of this paper we present an appropriate fragment of A2 and Tarski’s argument. In the second (...) part we consider an elementary interpreted language in which individual constants occur, but not functional symbols. For such a language we define semantically a relation of synonymity for simple names and show that it fulfills syntactical conditions formulated by Ajdukiewicz in A2 and allows synonymous names to exist with different denotations.

Once, G. E. Moore scorned the “common point of view which takes the world of experience as ultimately real.” The argument Moore followed to this sceptical conclusion in his fledgling 1897 fellowship dissertation was a legacy from Kant's Antinomies. By 1899 Moore had renounced idealist conclusions; he set out both to disengage from Kantian arguments and to reconcile with “the world of experience.” Moore's work for a stable realist basis for knowledge to fulfil both aims occupied his most famous argument, (...) in his 1939 lecture “Proof of an External World.” Moore himself is sometimes supposed to have thought the argument of this masterwork unsatisfactory where it treats a traditional sceptical puzzle posed by dreaming. Critics, including Wittgenstein, have portrayed Moore's best reply to philosophical scepticism as dogmatic mere assertion, unresponsive or as ineffectual as sheer handwaving. However, these critics rate Moore's success against scepticism based on interpretations of “Proof of an External World” that neglect its part in Moore's campaign against Kant. Consequently, some potentially pivotal questions — which in this study I merely broach — remain wide open; for example, why in presenting his famous 1939 proof did Moore state that its purpose was to refute what “Kant declares to be his opinion, that there is only one possible proof of the existence of things outside of us”? And why did Moore explicitly reject the formula for posing philosophical scepticism in which Kant famously proclaimed this problem “a scandal to philosophy”? (shrink)

It is argued that an instrumentalist notion of proof such as that represented in Hilbert's viewpoint is not obligated to satisfy the conservation condition that is generally regarded as a constraint on Hilbert's Program. A more reasonable soundness condition is then considered and shown not to be counter-exemplified by Godel's First Theorem. Finally, attention is given to the question of what a theory is; whether it should be seen as a "list" or corpus of beliefs, or as a method for (...) selecting beliefs. The significance of this question for assessing "intensional" results like Godel's Second Theorem, and their bearing on Hilbert's Program are discussed. (shrink)

Wittgenstein's Über Gewißheit shows his de facto commitment to the Three Condition Theory, according to which a knowledge-attribution implies belief, justification and truth, i.e., one can't be said to know that p unless (a) he believes that p; (b) he is in a position to justify p; and (c) 'p' is true. However, when it comes to tackling the puzzling infinite regress of justifications Wittgenstein's argument becomes entangled in an epistemological circle.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.1 (2004) 105-107 [Access article in PDF] Richard H. Popkin. The History of Scepticism: From Savonarola to Bayle. Revised and Expanded Edition. New York: Oxford University Press, 2003. Pp. xxiv + 415. Cloth, $74.00. Paper, $24.95. Richard Popkin tells the story that once a long time ago when he asked a question at a conference that made reference to late-eighteenth-century skeptics like (...) Maimon and Platner, Myles Burnyeat turned to the audience and asked, "Does anyone else read these people that Popkin reads?" The answer, by the time we get to this, the fourth edition of a book that first appeared in 1960, is that lots of people are reading the people that Popkin reads. Now [End Page 105] Myles Burnyeat is quoted on the cover of this volume for graciously saying "I regard it as one of the seminal books in the history of ideas." In one of the three Festschriften that have been published in Popkin's honor, David Katz even reports that some of those who work in areas Popkin pioneered refer to themselves as "Popkinites" (James E. Force and David S. Katz, eds., Everything Connects [Leiden and Boston: Brill, 1999], ix).Popkin was also founding editor of this journal, and his name has been footnoted in numerous articles over the years, so it will not be unknown to many. But readers will want to know what is new in this latest version of the classic work. For openers, it is roughly fifty percent longer, now 18 chapters instead of the 12 chapters of the last version. The original book was subtitled "From Erasmus to Descartes" and the later California edition subtitle became "From Erasmus to Spinoza." This edition pushes the envelope in both directions: back to Savonarola and forward to Pierre Bayle.The Savonarola connection comes from the unlikely discovery that the famous monk collected manuscripts of Sextus Empiricus and was planning to have them translated as tools for use against pagan philosophy and in favor of revealed religion. This brings out one of Popkin's favorite points: that what we think of as philosophical skepticism was part and parcel of religious debate early on. Among other new findings in this edition, Popkin finds clues that Leone Ebreo (Judah Abravanel) may have helped Gianfrancesco Pico read anti-Aristotelian Hebrew texts. Jews could use this sort of skepticism against the dogmatic Christians who tried to refute them.The religious connection is fundamental throughout the text. In his new introduction, Popkin admits that "I am more in sympathy with those who used the sceptical and fideist views of the nouveaux pyrrhoniens for religious rather than secular purposes" (p. xxiii). He has developed this sympathy into research on millenarianism in volumes such as Popkin and David S. Katz, Messianic Revolution: Radical Religious Politics to the End of the Second Millennium (New York: Hill and Wang, 1998) and Popkin, et al., eds., Millenarianism and Messianism in Early Modern European Culture, 4 vols. (Dordrecht: Kluwer, 2001).Other new materials follow the discussion of Descartes with a chapter on Henry More, Pascal, and the Quietists and another one on Hobbes's political and practical answer to skepticism. There are new chapters on Wilkins, Boyle, and Glanvill of the Royal Society, and on late seventeenth-century metaphysics. New material on Simon Foucher and Pierre-Daniel Huet is followed by the concluding chapter on Pierre Bayle as a "super sceptic."The book has never been uncontroversial. Although they could follow the skeptical undercutting of the Bible in Spinoza, many scholars could not see how the master of the geometrical method in ethics could be anything but a dogmatist in the final analysis. (Popkin has an answer.) The same doubt will now apply to the treatment of Pierre Bayle in this version. To Popkin, as we have seen, Bayle is a "super sceptic" who "carried scepticism to its ultimate extreme" (300); to Gianluca Mori (Bayle philosophe, Paris: Champion, 1999) and others, he is a dogmatic philosophical atheist as well as moral rigorist. To his credit... (shrink)

This paper discusses Wittgenstein's take on the problem of other minds. In opposition to certain widespread views that I collect under the heading of the “No Problem Interpretation,” I argue that Wittgenstein does address some problem of other minds. However, Wittgenstein's problem is not the traditional epistemological problem of other minds; rather, it is more reminiscent of the issue of intersubjectivity as it emerges in the writings of phenomenologists such as Husserl, Merleau-Ponty, and Heidegger. This is one sense in which (...) Wittgenstein's perspective on other minds might be called “phenomenological.” Yet there is another sense as well, in that Wittgenstein's positive views on this issue resemble the views defended by phenomenologists. The key to a proper philosophical grasp of intersubjectivity, on both views, lies in rethinking the mind. If we conceive of minds as essentially embodied we can understand how intersubjectivity is possible. (shrink)

1. Naturalism Naturalism, it has been said, is the distinctive development in philosophy over the last thirty years. There has been a naturalistic turn away from the a priori methods of traditional philosophy to a conception of philosophy as continuous with natural science. The doctrine has been extensively discussed and has won considerable following in the USA. This is, on the whole, not true of Britain and continental Europe, where the pragmatist tradition never took root, and the temptations of scientism (...) in philosophy were less alluring. Contemporary American naturalism originates in the writings of Quine, the metaphysician of twentieth-century science. With extraordinary panache, he painted a largescale picture of human nature, of language and of the web of belief. I believe that in almost every major respect, it is, like the picture painted by Descartes, the great metaphysician of seventeenth-century science, mistaken. But it evidently appeals to the spirit of the times. So it is worthy of critical examination and careful refutation. I shall argue that the naturalistic turn is a cul-de-sac – a turn that is to be passed by if we are to keep to the highroad of good sense. Naturalism, like so many of Quine’s doctrines, was propounded in response to Carnap. As Quine understood matters, Carnap had been persuaded by Russell’s Our Knowledge of the External World that it is the task of philosophy to demonstrate that our knowledge of the external world is a logical construction out of, and hence can be reduced to, elementary experiences. Quine rejected the reductionism of Carnap’s Logischer Aufbau, and found the idealist basis uncongenial to his own dogmatic realist behaviourism, inspired by Watson and later reinforced by Skinner. The rejection of reductionism and ‘unregenerate realism’, Quine averred, were the sources of his naturalism (FME 72). What exactly was this? We can distinguish in Quine between three different but inter-related programmes for future philosophy: epistemological, ontological and philosophical naturalism. Naturalized epistemology is to displace traditional epistemology, transforming the investigation into ‘an enterprise within natural science’ (NNK 68) – a psychological enterprise of investigating how the ‘input’ of radiation, etc., impinging on the nerve endings of human beings can ‘ultimately’ result in an ‘output’ of our theoretical descriptions of the external world.. (shrink)

In this paper, I compare and contrast two kinds of scepticism, Cartesian scepticism about the external world and Quinean scepticism about meaning. I expose Quine's metaphysical claim that there are no facts of the matter about meaning as a sceptical response to a sceptical problem regarding the possibility of our knowledge of meanings. I argue that this sceptical response is overkill; for the sceptical problem about our knowledge of meanings may receive a treatment similar to the naturalistic (...) treatment Quine himself offered for the problem of our knowledge of the external world. Further, I suggest that a naturalistic treatment of Quinean meaning scepticism may fare better than Quine's own naturalistic treatment of external world scepticism. (shrink)

Professor Grayling’s book provides an illuminating and insightful analysis of one variety of epistemological scepticism. It is not a study of scepticism per se; rather, it is an attempt to refute the claim that we can never be satisfactorily justified in our general assertions about the world.

In the Critique of Pure Reason, Kant uses the notion of spontaneity to characterize both the ordinary epistemic activity of the understanding and the kind of causal activity required for transcendentally free agency. In spite of the obvious differences between these two conceptions of spontaneity, at one time Kant virtually identified them, since he licensed the inference from the spontaneity of thought manifest in apperception to the transcendental freedom of the thinker. By the mid-1700s, however, he abandoned that view, affirming (...) instead a sharp distinction between “logical freedom,” which pertains to acts of thought, and “transcendental freedom,” which supposedly pertains to acts of will. This distinction, if not the precise language in which it was originally expressed, remained an integral part of the “critical” philosophy. Moreover, although the topic of freedom is not discussed in the Paralogisms, Kant there insists on the illegitimacy of the attempt to derive any synthetic knowledge regarding the nature of the “thing which thinks” from the ‘I think’.

Peter S. Fosl offers a radical interpretation of Hume as a thoroughgoing sceptic on epistemological, metaphysical and doxastic grounds. He first contextualises Hume's thought in the sceptical tradition and goes on to interpret the conceptual apparatus of his work - including the Treatise, Enquiries, Essays, History, Dialogues and letters.

Is the refutation of scepticism a central objective for Kant? Some commentators have denied that the refutation of either theoretical or moral scepticism was central to Kant's concerns. Thus, in his recent book Kant and the Fate of Autonomy, Karl Ameriks rejects 'taking Kant to be basically a respondent to the skeptic'. According to Ameriks, who here has Kant's theoretical philosophy in mind,What Kant goes on to propose is that, instead of focusing on trying to establish (...) with certainty – against skepticism – that the objects of common sense exist, let alone that they have philosophical dominance, or, in contrast, on explaining that it is only the theoretical discoveries of science that determine what is objective, one can rather work primarily to determine a positive and balanced philosophical relation between the distinct frameworks of our manifest and scientific images.

Galileo's refutation of the speed-distance law of fall in his Two New Sciences is routinely dismissed as a moment of confused argumentation. We urge that Galileo's argument correctly identified why the speed-distance law is untenable, failing only in its very last step. Using an ingenious combination of scaling and self-similarity arguments, Galileo found correctly that bodies, falling from rest according to this law, fall all distances in equal times. What he failed to recognize in the last step is that (...) this time is infinite, the result of an exponential dependence of distance on time. Instead, Galileo conflated it with the other motion that satisfies this ‘equal time’ property, instantaneous motion. (shrink)
