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)

Descartes claims that God is both incomprehensible and yet clearly and distinctly understood. This paper argues that Descartes’s development of the contrast between comprehension and understanding makes the role of God in his epistemology more interesting than is commonly thought. Section one examines the historical context of sceptical arguments about the difficulty of knowing God. Descartes describes the recognition of our inability to comprehend God as itself a source of knowledge of him; section two aims to explain how recognizing limits (...) to our cognitive powers is supposed to yield knowledge of anything other than ourselves. Section three aims to give a partial account of the role that awareness of the limitations of our cognitive powers is supposed to play in anchoring our knowledge of other things, and to show how such an approach to knowledge could still contribute to the development of a response to scepticism in the contemporary context.

Jessica Wilson has recently offered a more sophisticated version of the self-defeat objection to Cartesian scepicism. She argues that the assertion of Cartesian scepticism results in an unstable vicious regress. The way out of the regress is to not engage with the Cartesian sceptic at all, to stop the regress before it starts, at the warranted assertion that the external world exists. We offer three reasons why this objection fails: first, the sceptic need not accept Wilson’s (...) characterization of the sceptical thesis and thus need not start her regress; second, even if she did commit to the regress, it would not undermine scepticism in the way Wilson envisages; and third, the appeal to mental state scepticism which is necessary to generate the second and subsequent steps in the regress is not justified.

This article explores the relationship between epistemic relativism and Pyrrhonian scepticism. It is argued that a fundamental argument for contemporary epistemic relativism derives from the Pyrrhonian problem of the criterion. Pyrrhonian scepticism is compared and contrasted with Cartesian scepticism about the external world and Humean scepticism about induction. Epistemic relativism is characterized as relativism due to the variation of epistemic norms, and is contrasted with other forms of cognitive relativism, such as truth relativism, conceptual relativism (...) and ontological relativism. An argument from the Pyrrhonian problem of the criterion to epistemic relativism is presented, and is contrasted with three other arguments for epistemic relativism. It is argued that the argument from the criterion is the most fundamental argument for epistemic relativism. Finally, it is noted how the argument of the present paper fits with the author’s previous suggestion that a particularist response to the Pyrrhonian sceptic may be combined with a naturalistic view of epistemic warrant to meet the challenge of epistemic relativism.

The relation of scepticism to infallibilism and fallibilism is a contested issue. In this paper I argue that Cartesian sceptical arguments, i.e. sceptical arguments resting on sceptical scenarios, are neither tied to infallibilism nor collapse into fallibilism. I interpret the distinction between scepticism and fallibilism as a scope distinction. According to fallibilism, each belief could be false, but according to scepticism all beliefs could be false at the same time. However, to put this distinction to work (...) sceptical scenarios have to be understood as ignorance-possibilities, not as error-possibilities. To show that scepticism is not tied to infallibilism I reject the principle of unrestricted relevance according to which any error- or ignorance-possibility whatsoever is relevant. Instead I argue that the sceptic should distinguish between local and global ignorance-possibilities. Global ignorance-possibilities are relevant even though not all ignorance-possibilities are relevant. The result is a refined version of the Cartesian sceptical argument that avoids two traps other versions do not avoid. (shrink)

I focus on a key argument for global external world scepticism resting on the underdetermination thesis: the argument according to which we cannot know any proposition about our physical environment because sense evidence for it equally justifies some sceptical alternative (e.g. the Cartesian demon conjecture). I contend that the underdetermination argument can go through only if the controversial thesis that conceivability is per se a source of evidence for metaphysical possibility is true. I also suggest a reason to (...) doubt that conceivability is per se a source of evidence for metaphysical possibility, and thus to doubt the underdetermination argument. (shrink)

According to the standard view, Montaigne’s Pyrrhonian doubts would be in the origin of Descartes’ radical Sceptical challenges and his cogito argument. Although this paper does not deny this influence, its aim is to reconsider it from a different perspective, by acknowledging that it was not Montaigne’s Scepticism, but his Stoicism, which played the decisive role in the birth of the modern internalist conception of subjectivity. Cartesian need for certitude is to be better understood as an effect of (...) the Stoic model of wisdom, which urges the sage to build an inner space for self-sufficiency and absolute freedom. (shrink)

The Socratic Paradox (that only Socrates is wise, and only because only he recognizes our lack of wisdom) is explained, elaborated and defended. His philosophical scepticism is distinguished from others (Pyrrhonian, Cartesian, Humean, Kripkean Wittgenstein, etc.): the doubt concerns our understanding of our beliefs, not our justification for them; the doubt is a posteriori and inductive, not a priori. Post-Socratic philosophy confirms this scepticism: contra-Descartes, our ideas are not transparent to us; contra-Verificationism, no criterion distinguishes sense from (...) nonsense. The import of this scepticism for professional ethicists is examined. (shrink)

While the Academic sceptics followed the plausible as a criterion of truth and guided their practice by a doxastic norm, so thinking that agential performances are actions for which the agent assumes responsibility, the Pyrrhonists did not accept rational belief-management, dispensing with judgment in empirical matters. In this sense, the Pyrrhonian Sceptic described himself as not acting in any robust sense of the notion, or as ‘acting’ out of sub-personal and social mechanisms. The important point is that the Pyrrhonian advocacy (...) of a minimal conception of ‘belief’ was motivated by ethical concerns: avoiding any sort of commitment, he attempted to preserve his peace of mind. In this article, I argue for a Cartesian model of rational guidance that, in line with some current versions of an agential virtue epistemology, does involve judgment and risk, and thus which is true both to our rational constitution and to our finite and fallible nature. Insofar as epistemic humility is a virtue of rational agents that recognise the limits of their judgments, Pyrrhonian scepticism, and a fortiori any variety of naturalism, is unable to accommodate this virtue. This means that, in contrast to the Cartesian model, the Pyrrhonist does not provide a satisfactory answer to the problem of cognitive disintegration. The Pyrrhonist thus becomes a social rebel, one that violates the norm of serious personal assent that enables the flourishing of a collaborative and social species which depends on agents that, however fallible, are accountable for their actions and judgments.

In this essay I argue that Berkeley is proto-phenomenologist. The term phenomenology will chiefly be understood in terms of the approach of Edmund Husserl. Berkeley is attentive to the correct use of significations in philosophical exposition, the subjective character of experience, the motility of the perceiver and the transcendence of things. Like the phenomenologists he rejects materialism, naturalism and scepticism. He seeks to preserve the evidences of ordinary perception, setting out an account of scientific theory that can cohere with (...) them. In the first part of this essay I go through some of the more clear-cut ways in which Berkeley anticipates Husserl and some of the latter’s successors. In the second part I lay out their criticisms of Berkeley, also indicating what they hold in common. In the third and final part I consider some of the ways in which Berkeley can meet these criticisms, either readily or through certain qualifications, and I bring out his most significant contributions as a proto-phenomenologist. My aim is to show there are more than traces of the phenomenological attitude in Berkeley. In his efforts to save the appearances, he goes back to that world in which we live and breathe, if not quite have our being. (shrink)

The external world sceptic tells some familiar narratives involving massive deception. Perhaps we are brains in vats. Perhaps we are the victim of a deceitful demon. You know the drill. The sceptic proceeds by observing first that victims of such deceptions know nothing about their external environment and that second, since we cannot rule out being a victim of such deceptions our- selves, our own external world beliefs fail to attain the status of knowledge. Discussions of global external world (...) class='Hi'>scepticism tend to focus on the second step, where a number of well-known lines of resistance have been offered. But there has been little attention to the first, seemingly innocuous step. That will be the focus of this paper. Part one – sections 1, 2, and 3 – will explain why these standard narratives are not convincing examples of cases where there is no knowledge of the external world. In part two – section 4 – we shall undertake a useful case study. David Lewis’s ‘Elusive Knowledge’ is often thought of as presenting an epistemological vision that is somewhat friendly to external world scepticism: as Lewis himself presents things, there are contexts where external world knowledge ascriptions are uniformly false, and where true knowledge ascriptions are limited to either axiomatic truths or truths about our inner life. We examine his discussion in the light of the preceding reflections and show that the framework he presents is not so concessionary to global external world scepticism after all. (shrink)

A general trend in recent philosophical and empirical work aims to undermine various traditional claims regarding the distinctive nature of self-knowledge. So far, however, this work has not seriously threatened the Cartesian claim that (at least some) self-knowledge is immune to the sort of sceptical problem that seems to afflict our knowledge of the external world. In this paper I carry this trend further by arguing that the Cartesian claim is false. This is done by showing that a (...) familiar sceptical argument that targets my knowledge of the external world can be adapted to target my belief that I exist, along with any of my self-knowledge that I know entails my own existence. Thus, my self-knowledge and my knowledge of the external world are subject to the same sort of sceptical problem. (shrink)

Descartes has been accused of reasoning in a circle since the publication of the Meditations. The Circle is easy to point out: it seems that Descartes employs clear and distinct perceptions to demonstrate God’s existence and benevolence, and the latter, in turn, validates the use of clear and distinct perceptions. But is Descartes really guilty of fallacious argument, or can we break the arc somehow?

Stroud has argued for many years that skepticism is conditionally correct. We cannot, he claims, both undergo a Cartesian-style examination of the extent of our knowledge as well as avoid skepticism. One reason Stroud's position appears quite plausible is the so-called "totality condition" imposed for this kind of examination: as inquiring philosophers we are called upon to assess all of our knowledge, all at once. However, in this paper I argue that Stroud's apparent understanding of the totality condition is (...) mistaken. Evidently, Stroud thinks that honoring the totality condition amounts to imposing the strong requirement that we initially assume that we don't know anything about external reality. However, there is a weaker requirement available: that we initially not assume that we know anything about external reality. I argue i) that the weaker conception of the totality condition is most suitable for the kind of philosophical examination that Stroud seems to have in mind; and ii) that according to this same conception skepticism is not conditionally correct.

I am aware of the tree and its leaves, but am I aware of my awareness of these things? When I try to introspect my awareness, I just find myself attending to objects and their properties. This observation is known as the ‘transparency of experience’. On the other hand, I seem to directly know that I am aware. Given the first observation, it is not clear how I know that I am aware. Fred Dretske thought that the problem was so (...) acute that he issued the challenge of answering ‘How do you know that you are not a zombie?’ I propose that a view found in the Advaita Vedanta, that awareness is self luminous, reconciles these two observations. I understand self-luminosity as the thesis that: (1) I am implicitly aware of my awareness and (2) I am phenomenally aware of a distinct phenomenal character of my awareness. In support of the first claim, that I apparently only attend to objects in the world when introspecting perceptual experience, suggests that I do not know my awareness explicitly, but rather that I must know it implicitly. In support of the second claim, I argue that the mere fact that I am perceptually conscious is not sufficient to allow me to know that I am perceptually conscious. In particular, the qualities I am perceptually aware of do not tell me that I aware of them, rather they just seem to be properties of objects. I also assess whether strategies for responding to Cartesian sceptical scenarios can be employed against Dretske’s consciousness scepticism. I argue that these strategies either fail to distinguish me from a zombie or they do not adequately describe my epistemic situation. By contrast to other accounts, if awareness has its own distinct phenomenal character, then it cannot be considered to be a prima facie property of the world, hence the self-luminosity of awareness provides a plausible account of how I know that I’m not a zombie.

Imagine two urns, each with a thousand beads - in one all the beads are blue while in the other only one of the thousand is blue. If one of these urns is pushed forward (based on the toss of a fair coin) and the single bead then randomly drawn from it is blue, we must infer that it is a thousand times more probable that the urn pushed forward is the purely blue one. The hypothesis that this was instead (...) the urn with only one blue bead would require that the occurrence of the evidence, the blue bead being drawn, was something improbable - and it is improbable that something improbable is what has occurred. Next consider an example of only one urn with no prior description. By the same reasoning as above, if all the first beads randomly drawn are blue, it is becoming more and more probable that the beads in the urn are generally blue. (Otherwise something improbable would be happening in another colour not appearing; and what’s improbable is improbable.) It is therefore probable also that the next bead drawn will be blue. This is induction. As Hume would have said, we could not know a priori, given this evidence, that the next bead will be blue. But, as he overlooked, we can know a priori, given this evidence, that it is probable that the next bead will be blue. In neither urn example has the belief regarding the beads been formed as a Humean habit of expectation after many observations of beads. (In the first case there is only one observation. The second could be modified to have all the beads drawn out at once.) Rather the belief is a product of a priori reasoning about probability. Next imagine that a coin has been tossed a thousand times and landed heads every time. There was a fair and a loaded coin. According to the same reasoning, it is overwhelmingly more probable that the coin used was the loaded one. For that the fair coin had so landed is most improbable. The hypothesis that there is no external world makes the orderliness in my current experience improbable - much like getting all heads with a fair coin. (Uncaused sensation would most probably be chaotic.) The most probable hypothesis is that of things like those we believe in causing this orderliness - as the coin’s being loaded would have caused all heads. The hypothesis that my experience has been made to take this pattern by a Cartesian malicious demon or by scientists controlling my brain in a vat can only falsely seem to make the character of the experience probable by sneaking in an inherently improbable ad hoc specification that this sort of pattern of experience was that which they were aiming at producing - like an ad hoc specification that the fair coin was one that by chance landed heads all thousand times. We may thus reject such hypotheses as improbable. So this is the problem of induction solved and scepticism answered through a priori reasoning. (shrink)

Davidson’s antisceptical considerations, like Putnam’s, are transcendental in character: they start from facts that the sceptic has to accept, and are intended to show that those facts would not be such if the sceptical hypotheses were true. It is doubtful that these considerations are finally successful. However, I do not think that Davidson was really interested in a detailed refutation of scepticism. His interest focused instead on the context which gives rise to it: the Cartesian image of the (...) relationships between subjectivity, intersubjectivity, and objectivity. Correspondingly, the true value of Davidson’s antisceptical reflections lies in the alternative image that inspires them, in the light of which scepticism no longer appears as an urgent and interesting problem.

While philosophers have worried about mental causation for centuries, worries about the causal relevance of conscious phenomena are also increasingly featuring in neuroscientific literature. Neuroscientists have regarded the threat of epiphenomenalism as interesting primarily because they have supposed that it entails free will scepticism. However, the steps that get us from a premise about the causal irrelevance of conscious phenomena to a conclusion about free will are not entirely clear. In fact, if we examine popular philosophical accounts of free (...) will, we find, for the most part, nothing to suggest that free will is inconsistent with the presence of unconscious neural precursors to choices. It is only if we adopt highly non-naturalistic assumptions about the mind (e.g. if we embrace Cartesian dualism and locate free choice in the non-physical realm) that it seems plausible to suppose that the neuroscientific data generates a threat to free will.

This paper brings new work to bear on the perennial question about Hobbes's atheism to show that as a debate about scepticism it is falsely framed. Hobbes, like fellow members of the Mersenne circle, Descartes and Gassendi, was no sceptic, but rather concerned to rescue physics and metaphysics from radical scepticism by exploring corporealism. In his early letter of November 1640, Hobbes had issued a provocative challenge to Descartes to abandon metaphysical dualism and subscribe to a ?corporeal God?; (...) a provocation to which the Frenchman angrily responded, but was perhaps importantly influenced. Hobbes's minimal realism was consonant with atheism, to which Descartes felt he was being forced. Moreover, Hobbes was unrelenting in his battle against Cartesian dualism, for which he saw Robert Boyle's experimental science as a surrogate. (shrink)

The familiar Cartesian sceptical arguments all involve an explanation of our experiences. An account of the persuasive power of the sceptical arguments should explain why this is so. This supports a diagnosis of the error in Cartesian sceptical arguments according to which they mislead us into regarding our perceptual beliefs as if they were justified as inferences to the best explanation. I argue that they have instead a perceptual justification that does not involve inference to the best explanation (...) and that should not be put in doubt by the sceptical hypotheses. (shrink)

The first article of the cycle “The role of skeptical evidence in the First and Second ‘Meditations’” compares the Cartesian and Sextus Empiricus’ concepts of doubt in, respectively, “Metaphysical meditations” and “Outlines of Pyrrhonism”. The article starts with the current state of the problem “Descartes and skepticism” and admits the existence of consensus about Cartesian perception of skeptical tradition: Cartesius (1) was influenced by all skeptical movements, known in his time, and (2) created a generalized notion that contains (...) elements of both Academic and Pyrrhonian origin. This consensus is the source of many contemporary studies on how different skeptical doctrines influenced certain parts of Cartesian philosophy. This article attempts to analyze possible Descartes’ use of Sextus Empiricus’ notion of phenomenon. Sextus clearly states in “Outlines of Pyrrhonism” that one cannot doubt phenomenon as something perceived directly. The article proves that (a) Sextus’ thesis about the “sensory” nature of phenomenon is metaphorical, so far as it includes (without distinction) both sensuality and the experience of thinking; (b) the phenomenon is realized through a wide range of passive states of mind that all have irresistible force of influence; (c) the impact of phenomena is always mediated by our self, because all skeptical phrases are strictly correlated with the first person singular. Some researchers distinguish Sextus’ isostenia, as one of such insurmountable states, from Cartesian doubt at the First Meditation, which is allegedly based on a purely volitional decision. The article proved that this argument is artificial, since Descartes’ volitional decision is caused by initial inability to take the dubious as if it were certain. Thus, Cartesian approach can be considered a specific kind of isostenia. Such parallelism is a reason to assume a key role of Sextus’ understanding of insurmountable power of phenomena in Cartesian anti-sceptical argumentation. This assumption will be tested in the following articles of the cycle. (shrink)

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 in this paper that philosophers have not clearly introduced the concept of a body in terms of which the problem of other minds and its solutions have been traditionally stated; that one can raise fatal objections to attempts to introduce this concept; and that the particular form of the problem of other minds which is stated in terms of the concept is confused and requires no solution. The concept of a "body" which may or may not be the (...) body of a person, which is required to state the traditional problem, is, on close examination, incoherent and cannot be introduced into a reasonable philosophical discussion.

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative (...) ought judgments bring with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

The classical arguments for scepticism about the external world are defended, especially the symmetry argument: that there is no reason to prefer the realist hypothesis to, say, the deceitful demon hypothesis. This argument is defended against the various standard objections, such as that the demon hypothesis is only a bare possibility, does not lead to pragmatic success, lacks coherence or simplicity, is ad hoc or parasitic, makes impossible demands for certainty, or contravenes some basic standards for a conceptual or (...) linguistic scheme. Since the conclusion of the sceptical argument is not true, it is concluded that one can only escape the force of the argument through some large premise, such as an aptitude of the intellect for truth, if necessary divinely supported.

The present research (total N = 2,057) tested whether people’s folk conception of consciousness aligns with the notion of a “Cartesian Theater” (Dennett, 1991). More precisely, we tested the hypotheses that people believe that consciousness happens in a single, confined area (vs. multiple dispersed areas) in the human brain, and that it (partly) happens after the brain finished analyzing all available information. Further, we investigated how these beliefs arerelated to participants’ neuroscientific knowledge as well as their reliance on intuition, (...) and which rationale they use to explain their responses. Using a computer-administered drawing task, we found that participants located consciousness, but not unrelated neurological processes (Studies 1a & 1b) or unconscious thinking (Study 2) in a single, confined area in the prefrontal cortex, and that they considered most of the brain not involved in consciousness. Participants mostly relied on their intuitions when responding, and they were not affected by prior knowledge about the brain. Additionally, they considered the conscious experience of sensory stimuli to happen in a spatially more confined area than the corresponding computational analysis of these stimuli (Study 3). Furthermore, participants’ explicit beliefs about spatial and temporal localization of consciousness (i.e., consciousness happening after the computational analysis of sensory information is completed) are independent, yet positively correlated beliefs (Study 4). Using a more elaborate measure for temporal localization of conscious experience, our final study confirmed that people believe consciousness to partly happen even after information processing is done (Study 5).

I advocate scepticism about epistemic blame; the view that we have good reason to think there is no distinctively epistemic form of blame. Epistemologists often find it useful to draw a distinction between blameless and blameworthy norm violation. In recent years, this has led several writers to develop theories of ‘epistemic blame.’ I present two challenges against the very idea of epistemic blame. First, everything that is supposedly done by epistemic blame is done by epistemic evaluation, at least according (...) to a prominent view about the social role of epistemic evaluation. Parsimony considerations count against introducing an idle mechanism that does the same work as an existing one. Second, no current theory of epistemic blame includes a plausible account of the force of epistemic blame or the practices that could express it. I conclude that we should give up the notion of epistemic blame. (shrink)

This paper presents a particularist and naturalist response to epistemic relativism. The response is based on an analysis of the source of epistemic relativism, according to which epistemic relativism is closely related to Pyrrhonian scepticism. The paper starts with a characterization of epistemic relativism. Such relativism is explicitly distinguished from epistemological contextualism. Next the paper presents an argument for epistemic relativism that is based on the Pyrrhonian problem of the criterion. It then considers a response to the problem of (...) the criterion proposed by Roderick Chisholm, which is based on epistemological particularism. After sketching Chisholm’s approach, a response to epistemic relativism is presented which combines Chisholm’s particularism with epistemic naturalism and reliabilism. A number of objections to the position are then considered. The paper ends with remarks about the relationship between particularism and the naturalistic response proposed to epistemic relativism.

In this paper, we develop a novel response to counterfactual scepticism, the thesis that most ordinary counterfactual claims are false. In the process we aim to shed light on the relationship between debates in the philosophy of science and debates concerning the semantics and pragmatics of counterfactuals. We argue that science is concerned with many domains of inquiry, each with its own characteristic entities and regularities; moreover, statements of scientific law often include an implicit ceteris paribus clause that restricts (...) the scope of the associated regularity to circumstances that are ‘fitting’ to the domain in question. This observation reveals a way of responding to scepticism while, at the same time, doing justice both to the role of counterfactuals in science and to the complexities inherent in ordinary counterfactual discourse and reasoning.

While there seems to be much evidence that perceptual states can occur without being conscious, some theorists recently express scepticism about unconscious perception. We explore here two kinds of such scepticism: Megan Peters and Hakwan Lau's experimental work regarding the well-known problem of the criterion -- which seems to show that many purported instances of unconscious perception go unreported but are weakly conscious -- and Ian Phillips' theoretical consideration, which he calls the 'problem of attribution' -- the worry (...) that many purported examples of unconscious perception are not perceptual, but rather merely informational and subpersonal. We argue that these concerns do not undermine the evidence for unconscious perception and that this sceptical approach results in a dilemma for the sceptic, who must either deny that there is unconscious mentality generally or explain why perceptual states are unique in the mind such that they cannot occur unconsciously. Both options, we argue, are problematic. (shrink)

This paper deals with the philosophical problems concerned with research in the field of artificial intelligence (AI), in particular with problems arising out of claims that AI exhibits ‘consciousness’, ‘thinking’ and other ‘inner’ processes and that they simulate human intelligence and cognitive processes in general. The argument is to show how Cartesian mind is non-mechanical. Descartes’ concept of ‘I think’ presupposes subjective experience, because it is ‘I’ who experiences the world. Likewise, Descartes’ notion of ‘I’ negates the notion of (...) computationality of the mind. The essence of mind is thought and the acts of thoughts are identified with the acts of consciousness. Therefore, it follows that cognitive acts are conscious acts, but not computational acts. Thus, for Descartes, one of the most important aspects of cognitive states and processes is their phenomenality, because our judgments, understanding, etc. can be defined and explained only in relation to consciousness and not in relation to computationality. We can only find computationality in machines and not in the mind, which wills, understands and judges. (shrink)

To what extent are the answers to theological questions knowable? And if the relevant answers are knowable, which sorts of inquirers are in a position to know them? In this chapter we shall not answer these questions directly but instead supply a range of tools that may help us make progress here. The tools consist of plausible structural constraints on knowledge. After articulating them, we shall go on to indicate some ways in which they interact with theological scepticism. In (...) some cases the structural constraints bear directly on whether one can know answers to theological questions. But the structural considerations are related to theological scepticism in other interesting ways as well; for instance we will also be using them to explore the significance of scepticism, by addressing questions such as ‘To what extent does it matter whether or not we can know the answer to theological questions?’.

If it works, I can use Putnam’s vat argument to show that I have not always been a brain-in-a-vat. It is widely thought that the vat argument is of no use against closure scepticism – that is, scepticism motivated by arguments that appeal to a closure principle. This is because, even if I can use the vat argument to show that I have not always been a BIV, I cannot use it to show that I was not recently (...) envatted, and it is thought that the claim that I am not justified in thinking that I was not recently envatted is all that the closure sceptic requires. In this paper I first argue that scenarios in which I have been recently envatted are inadequate for the sceptic’s purposes, and so the standard argument that the vat argument is of no use against closure scepticism fails. I then argue that it is not possible to revise the standard argument to meet my objection. I conclude that, if it works, I can use the vat argument as a defence against closure scepticism. (shrink)

This paper evaluates an argument according to which many anthropologists commit themselves to Cartesian dualism, when they talk about meanings. This kind of dualism, it is argued, makes it impossible for anthropologists to adequately attend to material artefacts. The argument is very original, but it is also vulnerable to a range of objections.

The puzzle that concerns me is whether it is possible to establish a substantive difference between photographic images and other kinds of visual image, which can explain the special epistemic and aesthetic qualities of photographs, without giving way to scepticism about photographic art. In this essay I offer a philosophical account of the photographic process which is able to resolve this tension. I use this account to argue that, while some photographs are mind independent, mind independence is not a (...) defining feature of all photographs. My account is substantive because it distinctively distinguishes the photographic process from other image-making processes and is able to explain the special qualities of photographs. It is also schematic, because it covers the fullest range of photographic technologies across a comprehensive range of applications. Finally, it is clarificatory because it is able to clear up misunderstandings and resolve philosophical problems. Beyond these theoretical aims, my broader purpose is to provide an account that has applicability for a wide range of art history cases and, furthermore, is acceptable to photographic practitioners. The paper was first presented at the Stockholm Museum of Modern Art, in an interdisciplinary symposium. (shrink)

The irreducibility thesis of phenomenal consciousness can only succeed against the sceptical attack and avoid solipsism iff it can coherently establish the transition from subjective certainty to the objectivity of knowledge. The sceptical attack on the relationship between the phenomenal qualitative character of experience about the subjects own mental fact and the awareness of the qualitative properties of the phenomenal object can be avoided through establishing the immediacy of experience. The phenomenal realist become successful in establishing the subjective certainty about (...) the knowledge of phenomenal consciousness, however, has been failed in establishing objective certainty of knowledge, which leads to several epistemological problems (i.e., scepticism about the independent existence of external world, knowledge about the external reality and the existence of other mind; popularly known as the harder problem of consciousness) in philosophy of mind. In this paper, my objective is to reveal the undesirable consequences of representationalism. Representationalism is not an ideal option for responding to the sceptical attack against the other minds and the reality of the external world. It always leaves an open question for us about the relation between the representation of the object of experience and consciousness. Representationalistic theories of experience violates the principles of phenomenality by rejecting the immediacy of experience and has been committing the pragmatic contradiction by reducing the phenomenal properties to representational properties. The categorization of knowledge about phenomenality as inferential knowledge by representationalist leave no room for foundational knowledge about phenomenality. (shrink)

In this paper, I propose to analyse two objections raised by Turner Jr in his paper “On Two Reasons Christian Theologians Should Reject The Intermediate State” in order to show that the intermediate state is an incoherent theory.

Consequently, I shall defend an Intermediate State and I shall propose briefly one metaphysical conception of the human being able to reply to Turner (...) Jr’s objections. (shrink)

Justin Garson introduces the distinction between two views on Madness we encounter again and again throughout history: Madness as dysfunction, and Madness as strategy. On the latter view, Madness serves some purpose for the person experiencing it, even if it’s simultaneously harmful. The strategy view makes intelligible why Madness often holds a certain allure – even when it’s prima facie terrifying. Moreover, if Madness is a strategy in Garson’s metaphorical sense – if it serves a purpose – it makes sense (...) to use consciously chosen strategies for living with Madness that doesn’t necessarily aim to annihilate or repress it as far as possible. In this paper, we use our own respective stories as case studies. We have both struggled to resist the allure of Madness, and both ended up embracing a kind of Pyrrhonian scepticism about reality instead of clinging to sane reality. (shrink)

While many have argued that moral disagreement poses a challenge to moral knowledge, the precise nature of this challenge is controversial. Indeed, in the moral epistemology literature, there are many different versions of ‘the’ argument from moral disagreement to moral scepticism. This paper contributes to this vast literature on moral disagreement by arguing for two theses: 1. All (or nearly all) moral disagreement arguments share an underlying structure; and, 2. All moral disagreement arguments that satisfy this underlying structure cannot (...) establish moral scepticism because this underlying structure leads to a previously unrecognized reductio ad absurdum. In short, I argue that this reductio argument (very likely) refutes all versions of the moral disagreement to moral scepticism argument in one fell swoop. (shrink)

Abstract: Scepticism has only two moves to make and each is indefensible.

The first part of this paper will provide a reconstruction of Francis Bacon’s interpretation of Academic scepticism, Pyrrhonism, and Dogmatism, and its sources throughout his large corpus. It shall also analyze Bacon’s approach against the background of his intellectual milieu, looking particularly at Renaissance readings of scepticism as developed by Guillaume Salluste du Bartas, Pierre de la Primaudaye, Fulke Greville, and John Davies. It shall show that although Bacon made more references to Academic than to Pyrrhonian Scepticism, (...) like most of his contemporaries, he often misrepresented and mixed the doctrinal components of both currents. The second part of the paper shall offer a complete chronological survey of Bacon’s assessment of scepticism throughout his writings. Following the lead of previous studies by other scholars, I shall support the view that, while he approved of the state of doubt and the suspension of judgment as a provisional necessary stage in the pursuit of knowledge, he rejected the notion of acatalepsia. To this received reading, I shall add the suggestion that Bacon’s criticism of acatalepsia ultimately depends on his view of the historical conditions that surround human nature. I deal with this last point in the third part of the paper, where I shall argue that Bacon’s evaluation of scepticism relied on his adoption of a Protestant and Augustinian view of human nature that informed his overall interpretation of the history of humanity and nature, including the sceptical schools.

A common objection to Sosa’s epistemology is that it countenances, in an objectionable way, unsafe knowledge. This objection, under closer inspection, turns out to be in far worse shape than Sosa’s critics have realised. Sosa and his defenders have offered two central response types to the idea that allowing unsafe knowledge is problematic: one response type adverts to the animal/reflective knowledge distinction that is characteristic of bi-level virtue epistemology. The other less-discussed response type appeals to the threat of dream (...) class='Hi'>scepticism, and in particular, to the idea that many of our everyday perceptual beliefs are unsafe through the nearness of the dream possibility. The latter dreaming response to the safety objection to Sosa’s virtue epistemology has largely flown under the radar in contemporary discussions of safety and knowledge. We think that, suitably articulated in view of research in the philosophy and science of dreaming, it has much more going for it than has been appreciated. This paper further develops, beyond what Sosa does himself, the dreaming argument in response to those who think safety (as traditionally understood) is a condition on knowledge and who object to Sosa’s account on the grounds that it fails this condition. The payoffs of further developing this argument will be not only a better understanding of the importance of insights about dreaming against safety as a condition on knowledge, but also some reason to think a weaker safety condition, one that is relativised to SSS (i.e., skill/shape/situation) conditions for competence exercise, gets better results all things considered as an anti-luck codicil on knowledge.

This essay examines Descartes’s impact on medical faculties in the German Reformed context, focusing on the case of the Marburg physician Johann Jakob Waldschmidt (1644–89). It first surveys the wider backdrop of Descartes-reception in German universities, and highlights its generally conciliatory character. Waldschmidt appears as a counterpoint to this tendency. The essay then situates Waldschmidt’s work in the context of confessional politics at the University of Marburg, and specifically of the heightened controversy in Hesse around the teaching of Descartes in (...) the last years of Waldschmidt’s life. The second half of the essay details Waldschmidt’s ambitious program to reform medicine along Cartesian lines, in physiology, pathology, and therapy, and evaluates its merits and limits. (shrink)

This paper explicates Descartes’ theory of intuition (intuitus). Departing from certain commentators, I argue that intuition, for Descartes, is a form of clear and distinct intellectual perception. Because it is clear and distinct, it is indubitable, infallible, and provides a grade of certain knowledge he calls ‘cognitio’. I pay special attention to why he treats intuition as a form of perception, and what he means when he says it is ‘clear and distinct’. Finally, I situate his view in relation to (...) those of his Scholastic predecessors on one hand and current theories on the other. His view anticipates the contemporary ‘perceptual model of intuition’, though it is much bolder with its promise of certainty. (shrink)

Kant's response to scepticism in the Critique of Pure Reason is complex and remarkably nuanced, although it is rarely recognized as such. In this paper, I argue that recent attempts to flesh out the details of this response by Paul Guyer and Michael Forster do not go far enough. Although they are right to draw a distinction between Humean and Pyrrhonian scepticism and locate Kant's response to the latter in the Transcendental Dialectic, their accounts fail to capture two (...) important aspects of this response. The first is that Kant's response to Pyrrhonian scepticism is also a response to Hume. The second is that aspects of this response are decidedly positive. In particular, I argue (1) that Kant believed Hume's scepticism manifested important elements of Pyrrhonian scepticism and (2) that both Pyrrhonian scepticism and Hume had a significant positive influence on the development of the Transcendental Dialectic.

Crispin Wright maintains that the architecture of perceptual justification is such that we can acquire justification for our perceptual beliefs only if we have antecedent justification for ruling out any sceptical alternative. Wright contends that this principle doesn’t elicit scepticism, for we are non-evidentially entitled to accept the negation of any sceptical alternative. Sebastiano Moruzzi has challenged Wright’s contention by arguing that since our non-evidential entitlements don’t remove the epistemic risk of our perceptual beliefs, they don’t actually enable us (...) to acquire justification for these beliefs. In this paper I show that Wright’s responses to Moruzzi are ineffective and that Moruzzi’s argument is validated by probabilistic reasoning. I also suggest that Wright cannot answer Moruzzi’s challenge without weakening the support available for his conception of the architecture of perceptual justification. (shrink)

Interpreters of Hume on causation consider that an advantage of the ‘quasi-realist’ reading is that it does not commit him to scepticism or to an error theory about causal reasoning. It is unique to quasi-realism that it maintains this positive epistemic result together with a rejection of metaphysical realism about causation: the quasi-realist supplies an appropriate semantic theory in order to justify the practice of talking ‘as if’ there were causal powers in the world. In this paper, I problematise (...) the quasi-realist reading of Hume on causation by showing how quasi-realism does not speak to inductive scepticism. I also offer evidence that Hume takes inductive scepticism to result from his theory of causation, and that his scepticism is tied to his rejection of metaphysical causal realism. (shrink)
