This book argues that Hume is a radical epistemic skeptic who gives only practical reasons for retaining belief in sensory beliefs and the deliverances of reason. He advises us to take a moderate approach to the demands of philosophy, since they sometimes diverge from the demands of life.

The aim of this paper is to address the neglected but important problem of differentiating between epistemically beneficial and epistemically detrimental dissent. By “dissent,” we refer to the act of objecting to a particular conclusion, especially one that is widely held. While dissent in science can clearly be beneficial, there might be some instances of dissent that not only fail to contribute to scientific progress, but actually impede it. Potential examples of this include the tobacco industry’s funding of studies (...) that questioned the link between smoking and lung cancer, and the attempt by the petroleum industry and other groups to cast doubt upon the conclusion that human consumption of fossil fuels contributes to global climate change. The problem of distinguishing between good and bad dissent is important because of the growing tendency of some stakeholders to attempt to delay political action by ’manufacturing doubt’. Our discussion in this paper focuses on climate science. This field, in our view, is rife with instances of bad dissent. On the basis of our discussion of climate science, we articulate a set of sufficient conditions for epistemically problematic dissent in general, which we call “the inductive risk account of epistemically detrimental dissent.”.

In this introduction, I motivate the project of examining certain resonances between ancient skeptical positions, especially Pyrrhonism, and positions in contemporary epistemology, with special attention to recent work in the epistemology of science. One such resonance concerns the idea of suspension of judgment or belief in certain contexts or domains of inquiry, and the reasons for (or processes eventuating in) suspension. Another concerns the question of whether suspension of belief in such circumstances is voluntary, in any of the senses (...) discussed in current work on voluntarism in epistemology, which informs recent discussions of how voluntarism regarding epistemic stances may shed light on positions like scientific realism and antirealism. The aim of this special issue is thus to explore certain analogies and disanalogies between ancient and contemporary debates about skepticism, and to consider whether and to what extent the former can provide insight into the latter.

Paul Thagard has recently argued that thought experiments are dangerous and misleading when we try to use them as evidence for claims. This paper refutes his skepticism. Building on Thagard’s own work in cognitive science, I suggest that Thagard has much that is positive to say about how thought experiments work. My last section presents some new directions for research on the intersection between thought experiments and cognitive science.

Nathan Sasser's ‘purely practical reading of Hume’s response to skepticism’ is so natural and compelling that it is almost surprising that his new monograph, Hume and the Demands of Philosophy, offers its first systematic defence. I praise the book's clarity and concision, and then raise concerns about omitted topics, especially concerning Hume's views on the practical value of sceptical philosophy.

Modern science faces a series of problems that undermine confidence in its reliability. To solve these problems, we must reflect on what makes science work and what leads it astray. This book is about Science, its strengths and weaknesses. The papers that scientists write form a vast resource of evidence and theory that is doubling about every ten years, along with the number of scientists. The size of this resource makes it hard for it to be used (...) effectively by scientists, and along with this are growing concerns about its integrity and reliability. This book looks at the scientific method, as currently applied and as understood philosophically by scientists, the social structure of science, and the structure of scientific communication through journals. It includes case studies of controversies, and looks at how fields develop over time. (shrink)

Very little scholarly attention has been devoted to Part 1 of Hume's Dialogues Concerning Natural Religion. This lack has been addressed recently by Tweyman, who argues for the importance of this part in understanding the positions defended by the characters in the remainder of the dialogue, in accordance with the types that Hume discusses in part 12 of the Enquiry concerning Human Understanding—Cleanthes is a philosophical dogmatist who requires the application of excessive skepticism by Philo to turn to the (...) approved position of mitigated skepticism, while Demea is and remains a religious dogmatist. In the present paper I will address the question of why the Dialogues continues beyond Part 1 in the face of the statement by Philo, who is generally considered to be Hume's spokesperson in the dialogue, that the inquiry being undertaken—the investigation into the nature of the Deity—is beyond human reason.

The topic of expertise has become especially lively in recent years in academic discussions and debates about the politics of science. It is easy to understand why the topic holds such strong interest in Science & Technology Studies and related fields. There are at least two basic reasons for such interest. One is that experts are undoubtedly important in modern societies, and the other is that trends in STS research tend to be critical of the cognitive authority associated (...) with the public role of the expert. Putting the two together, STS researchers often align themselves with environmentalist and other movements that question the impartiality of experts and seek to democratize decisions about science and technology. Though such alignment is in many respects laudable, it can also be a source of confusion and misplaced political criticism. Toward the end of this brief synopsis of current STS research and debates on the topic of expertise, I will suggest an alternative agenda for engaging the politics of science and technology.

In this account of the philosophical and scientific pursuits of Pierre Gassendi , I challenge a traditional view which says that the inspiration, motivation, and demonstrative grounds for his physical atomism consist not in his empiricism but in his historicist commitments. Indeed, Gassendi suggests that it's a consequence of our best theory of knowledge and sound scientific method that we get evidence which warrants his microphysical theory. ;The primary novelty of his theory of empirical knowledge is his proposal, against the (...) Stoics and Descartes, that it is not a necessary condition of our knowing some claim that we are certain of it. This move immediately broadens the scope of what we can know through the senses, as does his suggestion that we include among such knowledge claims those assertions about what is hidden to the senses which we legitimately infer from the evidence of the perceptually given. ;On the basis of these epistemological positions, Gassendi develops his views on scientific method according to which we attain and justify our best empirical claims by deduction yet, he believes, these claims are at root probabilistic, and we may maintain hypotheses as the basis of our scientific reasoning so long as there is some empirical evidence for them, however broadly construed. ;Hence Gassendi suggests that his atomism constitutes a 'most likely hypothesis' for which we have empirical evidence--which of necessity is found indirectly in 'indicative' signs, those surface level phenomena for which he takes the existence of atoms to be a sine qua non condition. Perhaps the paramount case of such evidence consists in those microscopic observations of crystalline formation and dissolution that he takes to demonstrate the molecular structure of matter--a key and innovative consequence of his atomism. ;The robust character of Gassendi's method emerges in his appeals to indirect evidence for claims about the unobservable and his willingness to count this as adequate empirical grounds for maintaining an atomist hypothesis. Remarkably, he stands at the dawn of the modern era with at least a proposal as to how to resolve one of empiricism's more vexing difficulties, still with us in some form today. (shrink)

In The Ethics of Ambiguity (herein the Ethics), Simone de Beauvoir declares that science condemns itself to failure if it takes as its task the total disclosure of being (Beauvoir 1948/1976, 130). I suggest that the Ethics actually parallels the spirit of some scientific programs, specifically those that utilize positive skepticism as method. I draw out connections among the Ethics, Maurice Merleau-Ponty's Phenomenology of Perception (Merleau-Ponty 1945/1962) to which Beauvoir's works show much likeness, and Francis Bacon's The New (...) Organon (Bacon 1620/2000), the latter being at once a scientific and a positive skeptical program. Underscoring the ways in which Beauvoir's method of interrogating the being of beings and reality is compatible with some scientific pictures is important. It complicates the usual thought that existentialism is antiscience, problematizes Beauvoir's overly simplistic depiction of science, and nuances her analysis of the existent's experience of itself.

Watkins sets out in this book to provide an answer for Humean scepticism as it affects the philosophy of science. His carefully argued conclusions display the great fruitfulness--and limits--of the basic approach pioneered by Karl Popper. The development here goes well beyond Popper's own work, but is more in tune with it than, say, the latter-day views of Imre Lakatos.

Moral skepticism is at present a vibrant topic of philosophical inquiry. Particularly since the turn of the millennium, the metaethical study of skepticism has profited from advances in general epistemology and findings in empirical sciences, in light of which new arguments for and against moral skepticism have been devised, while the traditional ones have been reexamined. This collection of original essays by leading metaethicists will advance the ongoing debates about various forms of moral skepticism by drawing (...) on recent innovative work on moral disagreement, moral knowledge and justification, moral error theory, moral fictionalism, moral phenomenology, moral psychology, and evolutionary debunking of morality. It will be a valuable resource for professionals and advanced students working in the areas of moral philosophy and moral psychology. (shrink)

We live in a world that is increasingly shaped by and bathed in science, with most scientific progress occurring in the past century, and much of it in the past few decades. Yet, several authors have puz- zled over the observation that modern societies are also characterized by a high degree of belief in a variety of pseudoscientific claims that have been thoroughly debunked or otherwise discarded by scientists (Anonymous, 2001; Ede, 2000).

Radical skepticism endorses the extreme claim that large swaths of our ordinary beliefs, such as those produced by perception or memory, are irrational. The best arguments for such skepticism are, in their essentials, as familiar as a popular science fiction movie and yet even seasoned epistemologists continue to find them strangely seductive. Moreover, although most contemporary philosophers dismiss radical skepticism, they cannot agree on how best to respond to the challenge it presents. In the tradition of (...) the 18th century Scottish philosopher, Thomas Reid, Radical Skepticism and Epistemic Intuition joins this discussion by taking up four main tasks. First, it identifies the strongest arguments for radical skepticism, namely, underdetermination arguments, which emphasize the gap between our evidence and our ordinary beliefs based on that evidence. Second, it rejects all inferential or argument-based responses to radical skepticism, which aim to lay out good noncircular reasoning from the evidence on which we base our ordinary beliefs to the conclusion that those beliefs are probably true. Third, it develops a commonsense noninferential response to radical skepticism with two distinctive features: it consciously and extensively relies on epistemic intuitions, which are seemings about epistemic goods, such as knowledge and rationality, and it can be endorsed without difficulty by both internalists and externalists in epistemology. Fourth, and finally, it defends this commonsense epistemic-intuition-based response to radical skepticism against a variety of objections, including those connected with underdetermination worries, epistemic circularity, disagreement problems, experimental philosophy, and concerns about whether it engages skepticism in a sufficiently serious way.

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

Andreas Christiansen,Karin Jonch-Clausen,Klemens Kappel | : Many instances of new and emerging science and technology are controversial. Although a number of people, including scientific experts, welcome these developments, a considerable skepticism exists among members of the public. The use of genetically modified organisms is a case in point. In science policy and in science communication, it is widely assumed that such controversial science and technology require public participation in the policy-making process. We examine this view, (...) which we call the Public Participation Paradigm, using the case of GMOs as an example. We suggest that a prominent reason behind the call for public participation is the belief that such participation is required for democratic legitimacy. We then show that the most prominent accounts of democratic legitimacy do not, in fact, entail that public participation is required in cases of controversial science in general, or in the case of GMOs in particular. | : Beaucoup d’avancées scientifiques et de technologies émergentes sont controversées. Bien qu’un certain nombre de personnes, incluant des experts scientifiques, sont favorables à ces développements, la population demeure largement sceptique. Le recours aux organismes génétiquement modifiés illustre une telle situation. Dans les politiques et communications scientifiques, il est largement tenu pour acquis que de telles controverses scientifiques et technologiques requièrent la participation publique dans le processus de prise de décision politique. Nous examinons ce point de vue, que nous appelons le paradigme de la participation publique [Public Participation Paradigm], en nous servant du cas des OGM. Nous suggérons qu’une raison centrale en faveur de l’appel à la participation publique se situe dans la croyance qu’une telle participation est requise par la légitimité démocratique. Nous montrons ensuite que la plupart des principales conceptions de la légitimité démocratique n’impliquent pas, en fait, que la participation publique puisse être requise pour les controverses scientifiques en général, et pour les OGM en particulier.

This book develops new techniques in formal epistemology and applies them to the challenge of Cartesian skepticism. It introduces two formats of epistemic evaluation that should be of interest to epistemologists and philosophers of science: the dual-component format, which evaluates a statement on the basis of its safety and informativeness, and the relative-divergence format, which evaluates a probabilistic model on the basis of its complexity and goodness of fit with data. Tomoji Shogenji shows that the former lends support (...) to Cartesian skepticism, but the latter allows us to defeat Cartesian skepticism. Along the way, Shogenji addresses a number of related issues in epistemology and philosophy of science, including epistemic circularity, epistemic closure, and inductive skepticism. (shrink)

In this paper, I examine the epistemological positions of Philo and Cleanthes in the Dialogues. I find that Philo's attitude towards skepticism mirrors that of the first Enquiry, most notably in its endorsement of mitigated skepticism, and its treatment of religious reasoning as distinctly discontinuous with science and philosophy. Meanwhile, Cleanthes's epistemological framework corresponds to that of the Treatise, most notably in its adoption of something like the Title Principle, and its treatment of some forms of religious (...) reasoning as broadly continuous with science and philosophy. It is not merely that the epistemological systems of the Treatise and Enquiry are echoed in Cleanthes's and Philo's positions respectively; these frameworks seem to clarify, provide a substantive basis for, and render more complete their somewhat piecemeal statements on this topic in the Dialogues. Thus, Philo's and Cleanthes's dispute is not limited to the theological, but extends to the epistemological. -/- . (shrink)

Duhem’s problem arises especially in scientific contexts where the tools and procedures of measurement and analysis are numerous and complex. Several philosophers of cognitive science have cited its manifestations in fMRI as grounds for skepticism regarding the epistemic value of neuroimaging. To address these Duhemian arguments for skepticism, I offer an alternative approach based on Deborah Mayo’s error-statistical account in which Duhem's problem is more fruitfully approached in terms of error probabilities. This is illustrated in examples such (...) as the use of probabilistic brain atlases, comparison of different preprocessing protocols with respect to their error characteristics, and statistical modeling of fMRI data. These examples demonstrate the ways in which we can better understand and formulate the general methodological problem and direct the way toward alternative approaches to neuroimaging in philosophy of cognitive science, in which we can be more balanced and productive in our scrutiny of the epistemic value of neuroimaging studies.

In everyday life, we think of skepticism as the position of a stubborn person who has higher epistemic standards than others. Hence, the skeptic is someone who defends extravagant ideas. Some skeptics may deny that climate change is real, while others claim that the first moon landing did not take place. Contemporary philosophers think of skepticism in a different way. In their view, skepticism is the conclusion of a paradoxical argument about epistemic statuses like knowledge and reasons. (...) A paradoxical argument is a logically valid argument that, starting from seemingly plausible premises, reaches an absurd conclusion. We introduce two skeptical arguments. The regress argument purports to show that we lack reasons to believe any claim whatsoever because the search for those reasons inevitably leads to an infinite regress. The underdetermination argument seeks to prove that we lack reasons to believe that there are chairs, trees, other people, and so on; it supports that conclusion by citing skeptical hypotheses, including the idea that we might be dreaming (Descartes 1641) or the suggestion that we could be brains in a vat connected to a supercomputer that mimics the pattern of neural activity that would be produced if we were perceiving external objects (Putnam 1981).

The Science Wars have pitted defenders of science against those accused of attacking it with the weapons of constructivism and relativism. I argue that this defensive stance is in large part a consequence of two other -isms, organized skepticism and naïve methodism, that play a significant, if mostly unconscious, role in how scientists tend to think about science, and suggest that increased awareness of these -isms may help dissipate the perceptions of hostility.

In this book, Henrik Lagerlund offers students, researchers, and advanced general readers the first complete history of what is perhaps the most famous of all philosophical problems: skepticism. As the first of its kind, the book traces the influence of philosophical skepticism from its roots in the Hellenistic schools of Phyrronism and the Middle Academy up to its impact inside and outside of philosophy today. Along the way, it covers skepticism during the Latin, Arabic, and Greek Middle (...) Ages and during the Renaissance before moving on to cover Descartes's methodological skepticism and Pierre Bayle's super-skepticism in the seventeenth century. In the eighteenth century, it deals with Humean skepticism and the anti-skepticism of Reid and Kant, taking care to also include reflections on the connections between idealism and skepticism. The book covers similar themes in a chapter on G.E. Moore and Ludwig Wittgenstein, and then ends its historical overview with a chapter on skepticism in contemporary philosophy. In the final chapter, Lagerlund captures some of skepticism's impact outside of philosophy, highlighting its relation to issues like the replication crisis in science and knowledge resistance.

As a way of participating in the discussion on the disciplinary nature of philosophy of education, this article attempts to find another distinctive way of relating philosophy to education for the studies in philosophy of education. Recasting philosophical skepticism, which has been dismissed by Dewey and Rorty in their critiques of modern epistemology, it explores whether Cavell's romantic interpretation of it can allow us to conceive of skepticism as an exemplary practice of education, especially internal to the learner. (...) This opens up the possibility of viewing the disciplinary nature of philosophy of education as congenial to other humanities like literature or religious studies, rather than to social sciences as usually considered.

This paper challenges “biodiversity skepticism:” an inferential move that acknowledges the proliferation, heterogeneity, and lack of covariance of biodiversity measurements, and concludes that we should doubt the scientific validity of the biodiversity concept. As a way out of skepticism, philosophers have advocated for eliminating “biodiversity” from scientific inquiry, revising it, or deflating its meaning into a single measurable dimension. I present a counterargument to the inferential move of the skeptic by revealing how it stands on two unstated premises, (...) namely a reflective view of measurements and the unidirectional dynamics between definitional and measurement practices, and corollary assumptions. These premises and assumptions are misaligned with a richer theoretical understanding of measurement and are sometimes inconsistent with how science operates. A more nuanced view of measurement could better explain measurement proliferation while being consistent with new ways in which the general biodiversity concept could be useful. To conclude, I urge philosophers of measurement and conceptual engineers to collaborate in tackling the interplay between conceptual change and measurement practices. (shrink)

Ordinary skepticism is based upon some form of certainty. One may be skeptical about the claims of religion because one accepts the certainties of science or some philosophical argument. One may be skeptical about a certain investment strategy because one believes in various proven economic principles. Absoluteskepticism, on the other hand, has no such certainty upon which to rely. Every standpoint, including absolute skepticism itself, is open to doubt. Thus absolute skepticism is not another philosophical position (...) but raises severe doubt about all philosophy and all knowledge. In this paper I will explore some of the implications of absolute skepticism and how Lao Zi and Jiddu Krishnamurti (1895-1986) may serve as possible representatives of absolute skepticism. (shrink)

Kierkegaard's view of science and his rejection of the scientific systems of German idealism can be understood on the basis of his own emphasis on the necessity of a practical—rather than theoretical—comprehension of existence. Following the model of Socratic irony, he suggests that such comprehension rests on a skeptical attitude toward objective knowledge. As soon as skepticism opens up the possibility of an ethical approach to existence, however, the question is raised as to whether ethics itself, conceived of (...) as a form of knowledge, is able to give an account of existence in accordance with the presuppositions of the Christian dogma. Among those presuppositions, the notions of “sin” and “reconciliation” constitute a challenge to both pre‐Christian ethics and the epistemological framework within which this ethics situates itself. The transformation of such a framework would imply the founding of a “new science” able to embrace the idea of transcendence. (shrink)

During a period of great religious upheaval Anglican philosopher and ecclesiastic Henry Longueville Mansel (1820-1871) became famous for his 1858 Bampton Lectures, which sought to defend traditional faith by employing a skeptical philosophy. Understanding Mansel and the passionate debate that surrounded his career provides insight into the current struggle for ancient religions to articulate their traditions in a modern world. In Scripture, Skepticism, and the Character of God Dane Neufeld explores the life and thought of the now forgotten nineteenth-century (...) theologian. Examining the ideological differences between this philosopher and his contemporaries, Neufeld makes a case for the coherence of Mansel's position and traces the vestiges of his thought through the generations that followed him. Mansel found himself at the centre of an explosive debate in the church, concerning the Christian scriptures and the moral character of the God they described. Though the rise of science is often credited with provoking a crisis of doubt in the nineteenth century, shifting ideas about humanity and God were just as central to the spiritual unrest of the era. Mansel's central argument, that the entire Bible must be read as a unified witness to the reality of God, provoked disagreement among theologians, churchmen, and free thinkers alike who were uncomfortable with certain aspects of the scriptural portrayal of God's activity and character. Mansel's attempt to reconcile theological skepticism with scripturalism was misunderstood. He was branded a hopeless fideist by the free thinkers and a dangerous skeptic by high, broad, and evangelical churchmen alike. Many of the controversies in contemporary Christianity concern the collision between modern morality and biblical renderings of God. Neufeld argues that Henry Mansel, while a deeply polarizing figure, brought clarity and precision to this debate by exposing what was at stake for Christian belief and biblical interpretation in the Victorian period.

Naturalism, construed as the idea that philosophy should be continuous with science, is a highly influential view. Its consequences for epistemology, however, are rather odd. Many believe that naturalized epistemology allows eschewing traditional skeptical challenges. This is often seen as an advantage; but it also calls into question its claim of belonging to the philosophical inquiry into knowledge. This paper argues that skeptical challenges can be stated to defy epistemic optimism within naturalized epistemology, and that there are distinctively naturalistic (...) forms of skepticism. To that end, it outlines some assumptions underlying many attempts to naturalize epistemology. It contrasts these approaches to traditional epistemology and identifies the reasons offered by naturalistic epistemologists to dismiss traditional skeptical challenges. Next, it argues that the problem of skepticism can be sensibly stated within a naturalistic setting. Finally, it contends that there are distinctively naturalistic strategies to argue for skepticism and diagnoses the prospects of naturalism vis-à-vis these kinds of skeptical challenges. (shrink)

Dordrecht: Kluwer Academic Publishers, 1998. Pp. xix + 462. Cloth, $150.00.Who could reasonably question the importance of skepticism for the philosophical achievements of the period known as the Enlightenment? Skepticism seems to be the most appropriate means for illuminating a philosophical landscape shrouded in fog. The relatively restrained metaphor of “Aufklären” was used first by German philosophers to describe their project of removing prejudice and obscurity. British philosophers instead used the concept of “improvement,” and in France, the endeavours of the philosophes were largely associated with a determined fight against the dogmatic teachings of an all-powerful church and for religious and political freedom. But not every philosopher who employed skeptical arguments or the method of skepticism was therefore a skeptic, or someone who intended to establish a form of skepticism. And [End Page 171] some who sought to provide philosophy with a firm anti-skeptical foundation found themselves being accused of being skeptics themselves. Berkeley’s dogmatic Immaterialism was accused immediately of leading right away to the most abstruse kind of skepticism ever heard of, and Kant’s critical philosophy was forbidden in Hessia because of its alleged skepticism. Furthermore, many philosophers were indebted to some form of skepticism while not being skeptics themselves. Thus Reid’s common-sense-philosophy owed as much to Hume’s skeptical philosophy as did J. G. Hamann and F. H. Jacobi.Modern skepticism goes back to ancient Academic and Pyrrhonian Skepticism, which many philosophers of the Enlightenment for one reason or another still considered as a live option. But exactly what kind of skepticism their own writings entail and to what extent they were influenced by more modern types of skepticism—like that to be found in the works of Montaigne, Bayle, and others—is not always easy to decide. In addition, skepticism was sometimes viewed as a kind of systematic philosophy and the skeptic was considered to be a specific kind of philosopher, different from a Platonist, Stoic, or Epicurean, as in Hume for instance. But the vast majority of philosophers used skeptical arguments as instruments, or as the first step in laying the foundation for a new philosophical system. Finally, there are many much more subtle traces of skepticism in Enlightenment thought, which cannot always be put together easily in a comprehensive picture. The many-sided history of skepticism in the eighteenth century is accordingly difficult to tell.Richard H. Popkin’s work has been decisive for a further investigation of eighteenth century skepticism. His early “Scepticism in the Enlightenment” (1963) was seminal. Popkin pointed out in this article Hume’s central position. Hume marked the beginning of an increasing debate about different and variable types and contents of Enlightenment skepticism. Scepticism in the Enlightenment contains articles by Popkin himself, as well as articles by the late Giorgio Tonelli, known to many as an expert in Kant’s precritical philosophy, and by the late Ezequiel de Olaso, which were directly or indirectly occasioned by Popkin’s work. Only two of the ten articles are new (de Olaso on “Scepticism Old and New,” and Popkin’s very useful contribution on “Berkeley in the History of Scepticism”). But Tonelli’s “Kant and the Ancient Skeptics,” which appeared in 1967 in German, appears here for the first time in English translation. Although Tonelli’s scholarly article is still of interest today, Hume’s influence on Kant’s thought in the middle of the 1760’s should not be underestimated. Tonelli also seems to be too sceptical about Kant’s first-hand knowledge of ancient skepticism. For instance, Johann Matthias Gesner’s Chrestomathia Graeca (Leipzig, 1731), the school book used in the Greek class Kant attended as a... (shrink)

This chapter offers a new interpretation of Nietzsche’s argument for moral skepticism, an argument that should be of independent philosophical interest as well. On this account, Nietzsche offers a version of the argument from moral disagreement, but, unlike familiar varieties, it does not purport to exploit anthropological reports about the moral views of exotic cultures, or even garden-variety conflicting moral intuitions about concrete cases. Nietzsche, instead, calls attention to the single most important and embarrassing fact about the history of (...) moral theorizing by philosophers over two millennia: namely, that no rational consensus has been secured on any substantive, foundational proposition about morality. Persistent and apparently intractable disagreement on foundational questions, of course, distinguishes moral theory from inquiry in the sciences and mathematics. According to Nietzsche, the best explanation for this disagreement is that, even though moral skepticism is true, philosophers can still construct valid dialectical justifications for moral claims because the premises of different justifications will answer to the psychological needs of at least some philosophers and thus be deemed true by some of them. The chapter concludes by considering various attempts to defuse this abductive argument for scepticism. (shrink)

What chemists take as molecular structure is a theoretical construct based on the concepts of chemical bond, atoms in molecules, etc. and hence it should be distinguished from tangible structures around us. The practical adequacy of it has been demonstrated by the established method of retro-synthetic analysis, for instance. But it is not derived a priori from quantum mechanical treatments of the molecule and criticized for being irrelevant to the reality of the molecule. There is persistent skepticism about it. (...) The present study aims to overcome this skepticism by having recourse to the concepts of affordance and phenomenal field. The basic idea of our approach is suggested by the following statement of Niels Bohr: ‘evidence obtained under different experimental conditions cannot be comprehended within a single picture but must be regarded as complementary in the sense that only the totality of the phenomena exhausts the possible information about the objects’. This implies that we should take account of a context in which the cognition of a fact arises when we think about human activities including science. This can be realized by invoking affordances of a complex such as {agent, devices, methods, substances, surroundings}. That is to say, affordances are context-relative dispositional attributes of {agent-material world} complexes as is asserted by Harré and Llored. The phenomenal field is a conceptual device which schematizes the contextual aspect of affordance and, more importantly, serves as a link between the concept of affordance and Kant’s theory of knowledge, by which alone affordances are realized as the dispositional properties of {agent-material world} complexes. Because affordances become actualized in various phenomenal fields, affordances of one and the same object may well be distinct from one another. In conclusion we can take that molecular structure is the affordance of a complex that includes a chemist who is engaged in organic synthesis, whereas a quantum mechanical picture of the molecule may be one of the possible affordances of a complex that includes a quantum chemist who cares about electronic states of the molecule.

The Zhuangzi text deploys two epistemic themes to accomplish its ends of combatting human pretensions to know the world and to prompting us to rediscover the world through fresh eyes.

To point towards a more constructive relationship with Nature, it articulates the stance of being a mirror to nature. This essay will explain how the text does (...) this and relates its conceptions of skepticism and being as mirror to relevant contemporary science. (shrink)

We know very little about mathematical skepticism in modem times. Imre Lakatos once remarked that “in discussing modem efforts to establish foundations for mathematical knowledge one tends to forget that these are but a chapter in the great effort to overcome skepticism by establishing foundations for knowledge in general." And in a sense he was clearly right: modem thought — with its new discoveries in mathematical sciences, the mathematization of physics, the spreading of Pyrrhonist doctrines, the centrality of (...) epistemological foundationalism and the diffusion of the geometrical method in philosophy — was the most natural arena in which skepticism and mathematics could confront each other. The problem remains, however, that no investigation of the whole topic has yet been attempted. Thus, as far as we know, mathematical certainties should have clashed with skeptical doubts, but whether and to what extent there was indeed a historical debate on mathematical skepticism in modern thought remains to be ascertained.

This paper introduces Matraversian skepticism from aesthetics (i.e., there is no _cognitively_ interesting difference between our engagement with fiction versus our engagement with non-fiction) to debates in psychology and cognitive science on memory processing. I argue that the concept of ‘fiction’ has no place in our cognitive models of memory, neither in a specific category of memory, nor as a fact/fiction dimension. I propose a two-stage model of memory processing and explore the skeptical challenge that it poses to (...) existing accounts of the role of the concept of ‘fiction’ in models of memory. An important element of this challenge is the realization that remembering agents typically recognize a range of different kinds of non-fictional, non-believed memories, e.g., memories originating in lies, trickery, dreams, hallucinations, illusions, etc. (shrink)

Kurtz argues that there are objective standards for judging truth claims in science, ethics, and philosophy. Of special interest is the application of the new skepticism to paranormal claims such as reincarnation and faith healing, and to religious beliefs, ethics and politics.

Taber and Lodge's 2006 paper provides powerful evidence that one's prior beliefs shape one's reception of new evidence in a manner that can best be described as “inadvertently dogmatic.” This is especially true for people who are well informed, which dovetails with findings going back to Converse (1964) showing political beliefs to be ideologically constrained (rigid) among the relatively well informed. What may explain the coincidence of dogmatism and knowledgeability is the very process of learning about politics, which must use (...) theories, schemas, ideologies, or Lippmannesque “stereotypes” to target certain political information as germane by putting it into an interpretive framework. This interpretive process is likely to create for each of us a growing database of information that is congruent with our extant convictions but that excludes incongruent information: in light of the data we have already processed, incongruent information seems increasingly implausible (if not incomprehensible), and is therefore rationally ignored or dismissed. But this does not necessarily mean, as Taber and Lodge follow Robert Abelson in suggesting, that people are “motivated” to be dogmatic rather than being unintentionally closed minded as a result of the plausibility they involuntarily accord to their priors. Recognizing the inadvertent (unmotivated) nature of dogmatism is essential if political science is to take seriously political actors' beliefs—and to assess the gravity of the problem posed by dogmatism.

Both science itself, and the human culture of which it is a part, would benefit from a story of science that encourages wider engagement with and participation in the processes of scientific exploration. Such a story, based on a close analysis of scientific method, is presented here. It is the story of science as story telling and story revising. The story of science as story suggests that science can and should serve three distinctive functions for (...) humanity: providing stories that may increase human well-being, serving as a supportive nexus for human exploration and story telling in general, and exemplifying a commitment to skepticism and a resulting open-ended and continuing exploration of what might yet be. Some practical considerations that would further the development and acceptance of such a story of science as a widely shared nexus of human activity are described. (shrink)
