While many people today might turn to ancient Sanskrit philosophers for meditation or yoga, probably few would turn to them for help with difficult contemporary problems, such as what counts as "fake news" or navigating Internet debates. Philosopher Malcolm Keating argues that, in fact, a group of premodern Indian philosophers known as "Nyāya" have important things to say about how we can distinguish truth from falsity and reason well together, both of which are crucial to living a good life. -/- (...) In Reason in an Uncertain World, Keating teaches us what's distinctive in Nyāya approaches to knowledge and discussion, explaining these ideas in relationship to ordinary examples readers can understand. What are the limits of our reasoning? What counts as good evidence for our beliefs? How do we know if someone is a trustworthy source of information? What do we do when we are gripped by doubt? When is a debate with someone worth our time, and how can we discuss contentious topics? The answers to these questions are as relevant today as they were in ancient India. There, they were the focus of Nyāya philosophy, one of the most influential traditions of Indian philosophy, which few outside of scholarly communities have heard of. (shrink)

Arthâpatti is a pervasive form of reasoning investigated by Indian philosophers in order to think about unseen causes and interpret ordinary and religious language. Its nature is a point of controversy among Mimamsa, Nyaya, and Buddhist philosophers, yet, to date, it has received less attention than perception, inference, and testimony. This collection presents a one-of-a-kind reference resource for understanding this form of reasoning studied in Indian philosophy. Assembling translations of central primary texts together with newly-commissioned essays on research (...) topics, it features a significant introductory essay. Readable translations of Sanskrit works are accompanied by critical notes that introduce arthâpatti, offer historical context, and clarify the philosophical debates surrounding it. Showing how arthâpatti is used as a way to reason about the basic unseen causes driving language use, cause-and-effect relationships, as well as to interpret ambiguous or figurative texts, this book demonstrates the importance of this epistemic instrument in both contemporary Anglo-analytic and classical Indian epistemology, language, and logic.

Although there is increasing interest in philosophy of science in transcendental reasoning, there is hardly any discussion about transcendental arguments. Since this might be related to the dominant understanding of transcendental arguments as a tool to defeat epistemological skepticism, and since the power of transcendental arguments to achieve this goal has convincingly been disputed by Barry Stroud, this contribution proposes, first, a new definition of the transcendental argument which allows its presentation in a simple modus ponens and, second, a (...) pragmatist re-interpretation of this argument form that leaves it to the scientific community to debate, criticize, refine, or reaffirm its core claim: a premise which claims that the truth of a certain assumption is a necessary condition for something that is generally accepted. The proposed “logico-pragmatist interpretation” highlights the role of transcendental arguments as a methodological step to move science forward, just as abduction and inference to the best explanation do.

In classical India, debates over rational theology naturally become the occasion for fundamental questions about the scope and power of inference itself. This is well evinced in the classical proofs for God by the Hindu Nyāya tradition and the opposing arguments of classical Buddhists and Mīmāsā philosophers. This paper calls attention to, and provides analysis of, a number of key nodes in these debates, particularly questions of inferential boundaries and whether inductive reasoning has the power to support inferences to (...) wholly unique entities (like God).

Analytic philosophers have, since the pioneering work of B.K. Matilal, emphasized the contributions of Nyāya philosophers to what contemporary philosophy considers epistemology. More recently, scholarly work demonstrates the relevance of their ideas to argumentation theory, an interdisciplinary area of study drawing on epistemology as well as logic, rhetoric, and linguistics. This paper shows how early Nyāya theorizing about argumentation, from Vātsyāyana to Jayanta Bhaṭṭa, can fruitfully be juxtaposed with the pragma-dialectic approach to argumentation pioneered by Frans van Eemeren. I illustrate (...) the implications of this analysis with a case study from Jayanta Bhaṭṭa’s satirical play, Much Ado about Religion (Āgamaḍambara). (shrink)

Science is about evaluation, persuasion and logic. In scientific debate, scientists collectively evaluate theories by persuading each other in regard to epistemological qualities such as deduction and fact. There is, however, a flaw intrinsic to evaluation-by-persuasion: an individual can attempt and even succeed in persuading others by asserting that their reasoning is logical when it is not. This is a problem since, from an epistemological perspective, it is not always transparent nor obvious when a persuasive assertion is actually deductively (...) warranted. Empirical research upon reasoning, indeed, supports the notion that assertions are often strongly persuasive for reasons other than their logic. The unreliability of the link between persuasion and logic raises an important methodological issue: how do scientists debate in a manner such that claimed but false “logical” arguments are ignored, and only warranted arguments get to determine theory preference? This need for soundness in debate is a particularly important epistemological concern in cases where the deductive qualities of persuasive argument are not overt, and so cannot be directly checked --such as when they are founded upon Bayesianism probabilistic coherence. The argument presented here is that scientists make the qualities of probabilistic and nonprobabilistic inference sound (and so warranted) through how they organize their debate. Scientists, I argue, abide by “epistemological quality control practices” that limit the persuasive power of unsound arguments upon theory evaluation. Examples of such debate quality control practices are publicness, clarity, openness to criticism, and the collective promotion of attempts at theory conjecture and refutation. Methodologically, these quality control practices are extralogical since they do not directly provide scientific inferences with additional logical warrantedness. They function instead in science to generate an epistemological evaluative environment in which persuasiveness is due, and only due, to logic (i.e. sound). Their methodological role is therefore to make what is warranted de papyri (in our principles of rationality – epistemologically competence) also what is persuasive in evaluation and debate de cognitio (in our exercise of such principles – epistemologically performance). Several limitations exist upon the soundness of Bayesian inferential coherence – surreptitious revision, logical omniscience, uncertain evidence, old evidence, and new hypotheses. Bayesianism, as a result, can only exist if it is pursued in a debate that is regulated by quality control practices over its inferences (for instance, practices that ensure there is autonomy of inference, diligence of inference, probity of evidence, auditability of inference and assiduousness of conjecture). In this context, one can reinterpret Popper’s concern with criticism, openness, refutation and conjecture, as deriving not (as he thought) directly from the needs of logic, but, indirectly, from the need of scientists to create epistemological soundness.

In his notes, (...) Chakrabarti invites a reply "so that," as he says, "I may know why immaculate perception is needed by Nyāya after all." The following is a response that shows not so much why indeterminate perception is needed by Nyāya but why it is identified as a causal factor necessary to the arising of some (not all) determinate perception defined as "perception of an entity as qualified." Here I follow Gaṅgeśa Upādhyāya, the fourteenth-century founder (with the help of a few less well known predecessors and contemporaries) of "New Logic," Navya Nyāya. Gaṅgeśa devotes an entire section (about one eighteenth) of the perception chapter of his monumental Tattvacintāmaṇi (Jewel of Reflection about Epistemology) to nirvikalpaka pratyaksṣa,1 and he is a chief target of Chakrabarti's chastisement.2Now, first of all, I want to follow Gaṅgeśa's ground rules. The Naiyāyika is not concerned with strategies about how to look good in debates (with Buddhists or anyone else). His attitude is truth-seeking, not eristic, and thus no reply will be given to Chakrabarti's agonizing about how best to show ourselves in controversies with (in particular, Buddhist) adversaries (and Wilfrid Sellars). Gaṅgeśa's reflections are vāda—and the section is rightly titled nirvikalpaka-vāda, vāda being "inquiries among friends"—directed to uncovering real causal factors, not to winning a debate or countering sophisms. Deception, or counter-deception, is sometimes appropriate—for instance, to protect a student or other judge from fallacies advanced by people of bad character. But not here. So I will lay out Gaṅgeśa's argument for identifying nirvikalpaka pratyaksṣa, and then run through Chakrabarti's list of reasons for rejecting it with an eye to the objection's salience to Gaṅgeśa's project.

In this paper, I take up the conciliatory-steadfast debate occurring within social epistemology in regards to the phenomenon of peer disagreement. I will argue, because the conciliatory perspective al-lows us to understand argumentation pragmatically—as a method of problem-solving within a community rather than as a method for obtaining the truth—that in most cases, we should not simply agree to disagree.

The tradition of Nyāya philosophy centers on a dispassionate quest for truth which is simultaneously connected to soteriological and epistemic aims. This article shows how Vācaspati Miśra brings together the soteriological concept of dispassion with the discourse practices of debate, as a response to Buddhist criticisms in Dharmakīrti’s Vādanyāya. He defends the Nyāyasūtra’s stated position that fallacious reasoning is a legitimate means for a debate, under certain circumstances. Dharmakīrti argues that such reasoning is rationally ineffective and indicates unvirtuous (...) qualities. For Vācaspati, fallacies are a way to prevent the spread of morally weighty falsehoods when no other method is available to a debater. After showing textual relationships between Vācaspati’s defense and Dharmakīrti’s earlier criticism, it evaluates their arguments, concluding that Vācaspati’s position involves irresolvable tensions with other Nyāya commitments.

Besides seeing a rabbit or seeing that the rabbit is grayish, do we also sometimes see barely just the particular animal (not as an animal or as anything) or the feature rabbitness or grayness? Such bare, nonverbalizable perception is called "indeterminate perception" (nirvikalpaka pratyakṣa) in Nyāya. Standard Nyāya postulates such pre-predicative bare perception in order to honor the rule that awareness of a qualified entity must be caused by awareness of the qualifier. After connecting this issue with the Western debate (...) concerning the "myth of the given," seven distinct arguments are presented showing that the very notion of such indeterminate perception is epistemically otiose and that the Nyāya theory of perception is better off without it.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Epistemology in Pracīna and Navya NyāyaJonardon GaneriEpistemology in Pracīna and Navya Nyāya. By Sukharanjan Saha. Kolkata: Jadavpur University, 2003. Pp. 166.Epistemology in Pracīna and Navya Nyāya, by Sukharanjan Saha, usefully collates ten previously published essays on Indian epistemology: two longer essays first published in 1986 and a series of more recent shorter pieces. The leading thesis of the book is that the epistemology of the older writers in (...) the tradition of Nyāya-Vaiṣesika is, in important respects, better than the "new epistemology" originating with Gaṅgeśa. Sustained attention is given to the epistemology of the Vaiśeṣika thinker Praśastapāda (ca. A.D. 660), and the first six essays all "seek to show that Praśastapāda's views are more acceptable than those of Gaṅgeśa considered from the point of view of contemporary epistemology" (p. 4). The remaining essays argue in support of a similar conclusion with regard to certain ideas found in the older Nyāya of Gautama and Vātsyāyana. The titles of the essays collected here are: (1) "Epistemology in Pracīna and Navya Nyāya"; (2) "Kindred Points in an Old Epistemology" (1986); (3) "Gaṅgeśa's Reactions to Some Gettier-like Problems" (1986); (4) "The Unestab-lished Reason in Nyāya"; (5) "The Savyabhicāra Hetvābhāsa in Nyāya and Vaiśeṣika Schools"; (6) "The Thesis of Nirvikalpaka in Nyāya and Vaiśeṣika"; (7) "Truth as Avyabhicāritatva"; (8) "A Note on the Definition of Pramā; (9) "Nyāya Theory of Predication"; (10) "The Present and Its Knowledge"; and (11) "Types of Inference in Gautama and Vātsyāyana."Whether or not one finds oneself in agreement with Saha's specific arguments, the general conception of the book seems to me to be laudable. The astonishing [End Page 120] continuity of the Indian philosophical tradition makes it all too easy to survey the history of Indian philosophy and assume that historical development runs in tandem with philosophical progression. It is tempting to think, for example, that Gaṅśa, reviewing the epistemology of the older tradition, and considering the various objections that had been brought against it by external critics like Śrīharṣa and the later Buddhists, produced a new theory that was both an improvement on and a systematization of earlier Nyāya epistemology. To succumb to this temptation would be a mistake, however, for at least two reasons. First, it might be that the discussion of the earlier thinkers was, though less sophisticated, "closer to the ground," so to speak, than that of their successors. The comparative absence of theoretical baggage may have enabled those earlier writers to remain true to the facts, even when they could not easily be explained or systematized. This does indeed seem to be the case with the sūtra texts, and it is also very noticeably the case with Praśastapāda, who exhibited, for instance in his discussion of motion, an openness to the facts rather than closure born of theoretical over-commitment.Second and relatedly, it might be that the earlier thinkers had not yet closed down the range of topics and approaches deemed worthy of philosophical discussion or exploration. Thus, again in the sūtras, we find the beginnings of discussions on an enormous array of issues and hypotheses, not all of which were subsequently picked up or extended in later theory. Saha, for example, argues that Gaṅgeśa committed the later tradition to a rigid causal theory of knowledge, and suggests further that because of this he "failed to appreciate the richness of the philosophical insight of the founders of the system of philosophy to which he owes his allegiance" (p. 69). If this is right, then a return to the earlier strata of the tradition might well lead to an enrichment of our understanding of the range of philosophical possibility. Saha's approach, then, helps to guard the modern student of Indian philosophy from mistakenly thinking that "newer is always better," just as we have learned to be on guard against the older and contrary...

The classical Indian school called Nyāya (literally “logic” or “right reasoning”), is arguably the leading anti-skeptical tradition within all of Indian philosophy. Defending a realist metaphysics and an epistemology of “knowledge sources” (pramāṇa), its responses to skepticism are often appropriated by other schools of thought. This paper examines its responses to skeptical arguments from dreams, from “the three times,” from justificatory regress, and over the problem of induction.

The works of the Tibetan logician Phya pa Chos kyi seng ge (1109–1169) make abundant use of a particular type of argument that I term ‘argument by parallels’. Their main characteristic is that the instigator of the argument, addressing a thesis in a domain A, introduces a parallel thesis in an unrelated domain B. And in the ensuing dialogue, each of the instigator’s statements consists in replicating his interlocutor’s previous assertion, mutatis mutandis, in the other domain (A or B). I (...) show that such a dialogue involves two parallel arguments that develop in an intersecting zigzag pattern, and discuss the principles involved in the establishment of the conclusion from the perspective of parity of reasoning and analogical argument. I examine the overall rhetorical strategy directing the use of arguments by parallels and the pedagogical and explanatory functions they can serve. I also evaluate the plausibility of their use in Phya pa Chos kyi seng ge’s works mirroring a contemporary practice of oral debate, and reflect on the status of such arguments in the framework of Indo-Tibetan logic.

Are humans rational? Various experiments performed over the last several decades have been interpreted as showing that humans are irrational we make significant and consistent errors in logical reasoning, probabilistic reasoning, similarity judgements, and risk-assessment, to name a few areas. But can these experiments establish human irrationality, or is it a conceptual truth that humans must be rational, as various philosophers have argued? In this book, Edward Stein offers a clear critical account of this debate about rationality in (...) philosophy and cognitive science. He discusses concepts of rationality - the pictures of rationality that the debate centres on - and assesses the empirical evidence used to argue that humans are irrational. He concludes that the question of human rationality must be answered not conceptually but empirically, using the full resources of an advanced cognitive science. Furthermore, he extends this conclusion to argue that empirical considerations are also relevant to the theory of knowedge - in other words, that epistemology should be naturalized. from the reviews: 'Stein has done a great service in bringing together all of the important arguments in the human rationality debate and providing a measured critical assessment of them....

Until now, philosophical debate about human embryonic stem cell (hESC) research has largely been limited to its ethical dimensions and implications. Although the importance and urgency of these ethical debates should not be underestimated, the almost undivided attention that mainstream and feminist philosophers have paid to the ethical dimensions of hESC research suggests that the only philosophically interesting questions and concerns about it are by and large ethical in nature. My argument goes some distance to challenge the assumption that ethical (...) considerations alone must be foregrounded in philosophical discussions about hESC research by introducing a critical stance on the epistemological and ontological assumptions that underlie and condition it. A central aim of the paper is to show how Foucault's insights into knowledge-power, taken in combination with Hacking's claims about styles of reasoning, can make these assumptions evident, as well as cast light on their potentially deleterious implications for disabled people. Arguing in this way also enables me to draw out constitutive effects of research on stem cells, that is, to indicate how the discursive practices surrounding research on stem cells, as well as the technology itself, contribute to the constitution of impairment.

The essay examines intellectual virtue in the Summa theologiae, taking it as an interpretative key to the epistemology of the Summa theologiae as a whole. Because Aquinas blurs the line between the acquired and the theological virtues, and between virtues and the gifts of the Spirit, it becomes impossible to maintain the distinction between the realms of nature and grace, or between natural reason and revealed truth: grace permeates the most ordinary activities of human reasoning. This reading of the (...) Summa theologiae raises questions about many contemporary debates, particularly those concerning natural law. (shrink)

The Nyāya school of classical Indian epistemology defended (by today’s standards) a radical version of epistemic externalism. They also gave arguments from their epistemological positions to an early version of disjunctivism about perceptual experience. In this paper I assess the value of such an argument, concluding that a modified version of the Nyāya argument may be defensible.

Although there is increasing recognition that theory and practice in science are often inseparably intertwined, discussions of scientific controversies often continue to focus on theory, and not practice or methodologies. As a contribution to constructing a framework towards understanding controversies linked to scientific practices, we introduce the notion of borrowed epistemic credibility, to describe the situation in which scientists exploit fallacious similarities between accepted tenets in other fields to garner support for a given position in their own field. Our proposal (...) is based on the analysis of a recent controversy in phylogeography, a biological subdiscipline concerned with the study of the historical causes of variation in genetic diversity within species in concrete biogeographical locations. Through a review of the arguments that support the two conflicting phylogeographic schools, we show that ‘theory’ plays essentially no role as a foundation of the controversy, whereas both sides borrow epistemic credibility from sources such as formal logic, similarity of results to those in other scientific areas, the authority of prominent scientists, or the presumed superiority of quantitative vs. verbal reasoning. Our case study underscores the indivisibility of theory and practice and provide a means to re-examine important philosophical issues such as the meaning of inference, rationality, justification, and objectivity in scientific practice.

_ Source: _Volume 7, Issue 2, pp 114 - 135 It is a commonly accepted assumption in contemporary epistemology that we need to find a solution to ‘closure-based’ sceptical arguments and, hence, to the ‘scepticism or closure’ dilemma. In the present paper I argue that this is mistaken, since the closure principle does not, in fact, do real sceptical work. Rather, the decisive, scepticism-friendly moves are made before the closure principle is even brought into play. If we cannot avoid the (...) sceptical conclusion, this is not due to closure’s holding it in place, but because we’ve already been persuaded to accept a certain conception of perceptual reasons, which both issues a standing invitation to radical scepticism and is endemic in the contemporary literature. Once the real villain of the piece is exposed, it will become clear that the closure principle has been cast in the role of scapegoat in this debate. (shrink)

The book records a series of philosophical exchanges between its authors, amounting to a debate extended over more than fifteen years. Its subject matter is the nature and scope of reason. A central case at issue is basic logical knowledge, and the justification for basic deductive inferences, but the arguments range far more widely, at stake the distinctions between analytic and synthetic, and between a priori and a posteriori. The discussion naturally involves problems about the conditions for linguistic understanding and (...) competence, and what it might be to grasp a concept or to have an intuition. Since reason is central to philosophical method, there are associated implications for how philosophy itself works, or should work. In particular, the discussion raises fundamental concerns about how to approach epistemology. -/- . (shrink)

We call beliefs reasonable or unreasonable, justified or unjustified. What does this imply about belief? Does this imply that we are responsible for our beliefs and that we should be blamed for our unreasonable convictions? Or does it imply that we are in control of our beliefs and that what we believe is up to us? Reason Without Freedom argues that the major problems of epistemology have their roots in concerns about our control over and responsibility for belief. David Owens (...) focuses on the arguments of Descartes, Locke and Hume - the founders of epistemology - and presents a critical discussion of the current trends in contemporary epistemology. He proposes that the problems we confront today - scepticism, the analysis of knowlege, and debates on epistemic justification - can be tackled only once we have understood the moral psychology of belief. This can be resolved when we realise that our responsibility for beliefs is profoundly different from our rationality and agency, and that memory and testimony can preserve justified belief without preserving the evidence which might be used to justify it. Reason Without Freedom should be of value to those interested in contemporary epistemology, philosophy of mind and action, ethics, and the history of 17th and 18th century. (shrink)

This book defends a new interpretation of Hegel's theoretical philosophy, according to which Hegel's project in his central Science of Logic has a single organizing focus, provided by taking metaphysics as fundamental to philosophy, rather than any epistemological problem about knowledge or intentionality. Hegel pursues more specifically the metaphysics of reason, concerned with grounds, reasons, or conditions in terms of which things can be explained-and ultimately with the possibility of complete reasons. There is no threat to such metaphysics in epistemological (...) or skeptical worries. The real threat is Kant's Transcendental Dialectic case that metaphysics comes into conflict with itself. But Hegel, despite familiar worries, has a powerful case that Kant's own insights in the Dialectic can be turned to the purpose of constructive metaphysics. And we can understand in these terms the unified focus of the arguments at the conclusion of Hegel's Science of Logic. Hegel defends, first, his general claim that the reasons which explain things are always found in immanent concepts, universals or kinds. And he will argue from here to conclusions which are distinctive in being metaphysically ambitious yet surprisingly distant from any form of metaphysical foundationalism, whether scientistic, theological, or otherwise. Hegel's project, then, turns out neither Kantian nor Spinozist, but more distinctively his own. Finally, we can still learn a great deal from Hegel about ongoing philosophical debates concerning everything from metaphysics, to the philosophy of science, and all the way to the nature of philosophy itself.

In recent years, one of the important issues discussed in epistemology is the problem of disagreement. The epistemology of disagreement is mostly discussed through peer disagreement. The question of whether two epistemic peers should make a change in their beliefs after awareness of the disagreement is important in these discussions. To this question; there are four main answers: conciliationism, steadfastness, total evidence view, and justificationist view. In this thesis, I found these answers insufficient and put forward a new argument, which (...) i named as 'the evidence- based argument in peer disagreement'. Religious disagreements, with some of its cases that fall within the scope of peer disagreement, cause religious diversity. Whether religious diversity itself and religious disagreements will detract from the epistemological status of our religious belief is another matter of debate for religious epistemology. I have demonstrated that our religious belief is rational despite religious diversity and religious disagreements, both by using my argument and by putting forward various epistemological reasons.

Vatsyayana's Commentary on the Nyaya-sutra is one of classical India's most important philosophical works.

This paper argues for two interrelated claims. The first is that the most innovative contribution of Timothy Williamson, Herman Cappelen, and Max Deutsch in the debate about the epistemology of thought experiments is not the denial of intuition and the claim of the irrelevance of experimental philosophy but the claim of epistemological continuity and the rejection of philosophical exceptionalism. The second is that a better way of implementing the claim of epistemological continuity is not Deutsch and Cappelen’s argument view or (...) Williamson’s folk psychological view. This is so because while the argument view makes the basis of the relevant classificational judgement evidentially too demanding; the folk psychological view makes it too weak and error-prone to count as an adequate explanation. Drawing from a certain reading of Aristotle’s Nichomachean Ethics that flowers in Miranda Fricker and John McDowell, I argue for the reason-responsiveness view. Like the extant views, the reason-responsiveness view vindicates the claim of epistemological continuity. But unlike the extant views, it does not share those problematic features. Further, I show that the reason-responsiveness view offers a way for champions of the claim of epistemological continuity to resist Avner Baz’s objection to the claim of epistemological continuity and his objection to the philosophical use of thought experiments while taking on board some attractive elements of his view.

How ought we to go about forming and revising our beliefs, arguing and debating our reasons, and investigating our world? If those questions constitute normative epistemology, then I am interested here in normative metaepistemology: the investigation into how we ought to go about forming and revising our beliefs about how we ought to go about forming and revising our beliefs -- how we ought to argue about how we ought to argue. Such investigations have become urgent of late, for the (...) methodology of epistemology has reached something of a crisis. For analytic epistemology of the last half-century has relied overwhelmingly on intuitions,1 and a growing set of arguments and data has begun to call this reliance on intuition seriously into question (e.g., Weinberg, Nichols, and Stich 2001; Nichols, Stich, and Weinberg 2003; Cummins 1998). Although that method has not been entirely without defenders (BonJour 1998; Bealer 1996; Jackson 1998; Sosa forthcoming; Weatherson 2003), these defenses have not generally risen to the specific challenges leveled by the anti-intuitionist critics. In particular, the critics have attacked specific ways of deploying intuitions, and the defenders have overwhelmingly responded with in-principle defenses of the cogency of appealing to intuition. An analogy here would be someone’s responding to arguments alleging systematic.. (shrink)

Different views on the connection between relativism and feminist epistemologies are often asserted but rarely are these views clearly argued for. This has resulted in a confusingly polarised debate, with some people convinced that feminist epistemologies are committed to relativism (and that this is a reason so be suspicious of them) whilst others make similar criticisms of anti-feminist views and argue that relativism has no place in feminist epistemologies. This chapter is an attempt to clarify this debate. I begin by (...) asking the question “are feminist projects and goals best served by relativism, or by absolutism?” I then sketch out four broad positions one could take on the answer to this question, and evaluate arguments for each one. In the end I conclude that feminist projects can, at least sometimes, be served by relativism, and that the claim they can be served by anti-relativism is under-supported. (shrink)

A long-standing debate surrounds the question as to what justifies memory judgements. According to the Past Reason Theory, these judgements are justified by the reasons we had to make identical judgements in the past, whereas the Present Reason Theory claims that these justifying reasons are to be found at the time we pass the memory judgements. In this paper, I defend the original claim that, far from being exclusive, these two theories should be applied to different kinds of memory judgements. (...) The Past Reason Theory offers the most appealing account of justified propositional memory judgements, while the Present Reason Theory provides the best approach to justified episodic memory judgements. One outcome of my discussion is thus that memory is not epistemologically unified and my argument in favour of this conclusion connects with the issues of internalism, reliabilism and the basing relation.

This essay aims to sharpen debates on the pros and cons of historical epistemology, which is now understood as a novel approach to the study of knowledge, by comparing it with the history of epistemology as traditionally pursued by philosophers. The many versions of both approaches are not always easily discernable. Yet, a reasoned comparison of certain versions can and should be made. In the first section of this article, I argue that the most interesting difference involves neither the subject (...) matter nor goal, but the methods used by the two approaches. In the second section, I ask which of the two approaches or methods is more promising given that both historical epistemologists and historians of epistemology claim to contribute to epistemology simpliciter . Using traditional problems concerning the epistemic role of perception, I argue that the historical epistemologies of Wartofsky and Daston and Galison fail to show that studying practices of perception is philosophically significant. Standard methods from the history of epistemology are more promising, as I show by means of reconstructing arguments in a debate about the relation between perception and judgment in psychological research on the famous moon illusion.

The epistemology of śabda is one of the main themes in Bhaṭṭa Jayanta’s Nyāyamañjarī, and, in the hypotheses explored in this paper, also the conceptual basis of Jayanta’s textual re-use. The sixth chapter of the Nyāyamañjarī contains a debate between Vaiyākaraṇas and Mīmāṃsakas who, respectively, advocated an holistic or atomistic theory of language. Selected Jayanta’s re-uses from Vyākaraṇa, Mīmāṃsā, and Nyāya sources are here surveyed and analyzed, with a focus on their meaning and on the context. The method of analysis (...) is partially following Moravcsik’s scheme for a classification of citations, as well as Small’s classification by symbolic functions. By re-using texts Jayanta not only imparted authority to his own arguments, but also reassessed the relation of his tradition with other ones. Re-used ideas and words stand for symbols of those authors’ tenets, and those authors represent symbols of their respective traditions. Moreover, by quoting a certain author Jayanta often anointed him with a symbolic status of trustworthy authority, and his statement with a status of śabdapramāṇa. (shrink)

Abstract This paper outlines the proposal that narratives can back up the claim that explanations by reasons are causal explanations. While drawing for inspiration on discussions in the philosophy of history, the proposal is here discussed in the context of the classical debate about reasons and causes. The far-reaching agreement of Davidson's causalist theory with an anti-causalist argument is shown to give rise to an epistemological difficulty that is not fixed simply by attending to his understanding of singular causal claims. (...) Elements for the outlined narrativist solution in turn can be discerned in the writings of the anti-causalist opposition and were further developed in the work of a philosopher who turned from anti-causalist to causalist about reasons?albeit not to defend the Davidsonian theory.

Disputants in the debate regarding whether Hume's argument on induction is descriptive or normative have by and large ignored Hume’s positive argument (that custom is what determines inferences to the unobserved), largely confining themselves to intricate debates within the negative argument (that inferences to the unobserved are not founded on reason). I believe that this is a mistake, for I think Hume’s positive argument to have significant implications for the interpretation of his negative argument. In this paper, I will argue (...) that Hume’s positive and negative arguments should be read as addressing the same issues, whether normative or causal. I will then focus on the Enquiry version of Hume’s positive argument, arguing that it carries a significant normative conclusion: there, Hume argues that custom plays a normative role in justifying our inductive inferences. Given that Hume’s positive argument should be read as addressing the same issues as his negative argument, we should correspondingly read Hume’s negative argument in the Enquiry as having a normative conclusion.

What I have tried to do is elicit and disarm the motivations most likely to give rise to the [counterexamples to the principle crucial to Williams' argument]. Only one of these motivations is still viable: the instrumentalist theory of practical reasoning. But because internalism and instrumentalism are, as it has turned out, so very tightly linked, in disarming the motivations for the objection, I have also inventoried, and given reason to reject, what I have found to be the most (...) common conversationally adduced defences of instrumentalism: the appeals to imagination, to dispositional desires, and so on. The issue remaining from the debate over internalism turns out to be whether [instrumentalism is false---i.e. whether] there are patterns of practical inference that are not directed toward the satisfaction of desire.

The Doomsday argument purports to show that the risk of the human species going extinct soon has been systematically underestimated. This argument has something in common with controversial forms of reasoning in other areas, including: game theoretic problems with imperfect recall, the methodology of cosmology, the epistemology of indexical belief, and the debate over so-called fine-tuning arguments for the design hypothesis. The common denominator is a certain premiss: the Self-Sampling Assumption. We present two strands of argument in favor of (...) this assumption. Through a series of thought experiments we then investigate some bizarre prima facie consequences – backward causation, psychic powers, and an apparent conflict with the Principal Principle.

This paper argues that treating James' "The Will to Believe" as a defense of prudential reasoning about belief seriously misrepresents it. Rather than being a precursor to current defenses of prudential arguments, James paper has, if anything, more affinities to certain prominent strains in contemporary naturalized epistemology.

Few, if any, scientific inquiries are conducted against a background of complete knowledge, a background in which inquirers are in possession of the ‘full facts’ that relate to a particular question or issue. More often than not, scientists are compelled to conduct their deliberations in contexts of epistemic uncertainty, in which partial knowledge or even a total absence of knowledge characterise inquiry. Nowhere is this epistemic uncertainty more evident, or indeed more successfully controlled, than in the branch of scientific inquiry (...) called epidemiology. In this paper, I examine how epidemiologists overcome the unique challenges to inquiry that are posed by epistemic uncertainty. In specific terms, I contend that epidemiologists employ analogical reasoning strategies in an attempt to advance their inquiries in situations that are epistemically uncertain. The context for my claims will be the early inquiries that were conducted into the emergence of HIV/AIDS in the United States. I argue that early scientific work in relation to HIV/AIDS was directly premised upon epidemiological investigations in which analogical reasoning with hepatitis B had featured significantly. I conclude that epidemiological investigations of AIDS exemplify the capacity of analogical reasoning to advance inquiry under conditions of epistemic uncertainty. To this extent, analogical reasoning should be a concern both to those who address practical problems of uncertainty management and to those who pursue theoretical debates within argumentation studies and epistemology.

After decades of receiving a lot of attention on the epistemological level, the so-called ‘problem of intuitions’ is now in the center of debates on the metaphilosophical level. One of the reasons for this lies in the unfruitfulness of the epistemological discussions that recently subsided without producing any significant or broadly accepted theory of intuitions. Consequently, the metaphilosophical level of discussion of the ‘problem of intuitions’ inherits the same difficulties of the epistemological level. The significance of Max Deutsch’s book The (...) Myth of the Intuitive is his effort to resolve these problems in a clear and persuasive way. He is not only trying to debunk problems behind the vagueness of the ‘intuition-talk’ by drawing important distinctions that usually go under the radar in the contemporary literature, but also develops his own account of philosophical methodology. In this paper I will present some of his arguments against the traditional view of intuitional methodology, as well as his own solutions to the presented problems. Regardless of Deutsch’s insightful account of the ‘problem of intuitions’, I find that some difficulties in his own proposal are inherited from the unresolved issues of intuitions on the epistemological level.

In this detailed study, Christopher Norris defends the kinds of arguments advanced by the early realist, Hilary Putnam. Norris makes a point of placing Putnam's work in a wider philosophical context, and relating it to various current debates in epistemology and philosophy of science. Much like Putnam, Norris is willing to take full account of opposed viewpoints while maintaining a vigorously argued commitment to the values of debate and enquiry.

After the challenges of the Enlightenment from philosophers such as David Hume, contemporary philosophers of religion tend to think that proof is not possible and that at best humans have arguments for the probability or plausibility of belief in God. But, Christianity maintains that humans should know God. This book explores attempts to respond to the Enlightenment challenges by thinkers at Princeton Theological like Benjamin Warfield. It considers Warfield's view of reason and knowledge of God, his debate with Abraham Kuyper, (...) and the attempt to reconcile differences between these two by Cornelius Van Til. It also considers Reformed Epistemology, which has become popular in recent decades and is credited for a renewed interest in Christian philosophy. (shrink)

A good part of the early literature on deliberative democracy has focused on moral arguments for or against deliberative democracy. These arguments have typically been divided into instrumental and non‐instrumental arguments. More recently, there has been an epistemic turn in the literature on deliberative democracy. The main question under debate is no longer whether we have moral reasons to make our political decisions in deliberative democratic fashion, but whether or not we have epistemic reasons to do so. Epistemic arguments for (...) and against deliberative democracy can also be divided instrumental and non‐instrumental arguments. My chapter on the epistemology of deliberative democracy will give an overview over this new debate. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Epistemology in Pracīna and Navya NyāyaJonardon GaneriEpistemology in Pracīna and Navya Nyāya. By Sukharanjan Saha. Kolkata: Jadavpur University, 2003. Pp. 166.Epistemology in Pracīna and Navya Nyāya, by Sukharanjan Saha, usefully collates ten previously published essays on Indian epistemology: two longer essays first published in 1986 and a series of more recent shorter pieces. The leading thesis of the book is that the epistemology of the older writers in (...) the tradition of Nyāya-Vaiṣesika is, in important respects, better than the "new epistemology" originating with Gaṅgeśa. Sustained attention is given to the epistemology of the Vaiśeṣika thinker Praśastapāda (ca. A.D. 660), and the first six essays all "seek to show that Praśastapāda's views are more acceptable than those of Gaṅgeśa considered from the point of view of contemporary epistemology" (p. 4). The remaining essays argue in support of a similar conclusion with regard to certain ideas found in the older Nyāya of Gautama and Vātsyāyana. The titles of the essays collected here are: (1) "Epistemology in Pracīna and Navya Nyāya"; (2) "Kindred Points in an Old Epistemology" (1986); (3) "Gaṅgeśa's Reactions to Some Gettier-like Problems" (1986); (4) "The Unestab-lished Reason in Nyāya"; (5) "The Savyabhicāra Hetvābhāsa in Nyāya and Vaiśeṣika Schools"; (6) "The Thesis of Nirvikalpaka in Nyāya and Vaiśeṣika"; (7) "Truth as Avyabhicāritatva"; (8) "A Note on the Definition of Pramā; (9) "Nyāya Theory of Predication"; (10) "The Present and Its Knowledge"; and (11) "Types of Inference in Gautama and Vātsyāyana."Whether or not one finds oneself in agreement with Saha's specific arguments, the general conception of the book seems to me to be laudable. The astonishing [End Page 120] continuity of the Indian philosophical tradition makes it all too easy to survey the history of Indian philosophy and assume that historical development runs in tandem with philosophical progression. It is tempting to think, for example, that Gaṅśa, reviewing the epistemology of the older tradition, and considering the various objections that had been brought against it by external critics like Śrīharṣa and the later Buddhists, produced a new theory that was both an improvement on and a systematization of earlier Nyāya epistemology. To succumb to this temptation would be a mistake, however, for at least two reasons. First, it might be that the discussion of the earlier thinkers was, though less sophisticated, "closer to the ground," so to speak, than that of their successors. The comparative absence of theoretical baggage may have enabled those earlier writers to remain true to the facts, even when they could not easily be explained or systematized. This does indeed seem to be the case with the sūtra texts, and it is also very noticeably the case with Praśastapāda, who exhibited, for instance in his discussion of motion, an openness to the facts rather than closure born of theoretical over-commitment.Second and relatedly, it might be that the earlier thinkers had not yet closed down the range of topics and approaches deemed worthy of philosophical discussion or exploration. Thus, again in the sūtras, we find the beginnings of discussions on an enormous array of issues and hypotheses, not all of which were subsequently picked up or extended in later theory. Saha, for example, argues that Gaṅgeśa committed the later tradition to a rigid causal theory of knowledge, and suggests further that because of this he "failed to appreciate the richness of the philosophical insight of the founders of the system of philosophy to which he owes his allegiance" (p. 69). If this is right, then a return to the earlier strata of the tradition might well lead to an enrichment of our understanding of the range of philosophical possibility. Saha's approach, then, helps to guard the modern student of Indian philosophy from mistakenly thinking that "newer is always better," just as we have learned to be on guard against the older and contrary...

Many who take a dismissive attitude towards metaphysics trace their view back to Carnap’s ‘Empiricism, Semantics and Ontology’. But the reason Carnap takes a dismissive attitude to metaphysics is a matter of controversy. I will argue that no reason is given in ‘Empiricism, Semantics and Ontology’, and this is because his reason for rejecting metaphysical debates was given in ‘Pseudo-Problems in Philosophy’. The argument there assumes verificationism, but I will argue that his argument survives the rejection of verificationism. The root (...) of his argument is the claim that metaphysical statements cannot be justified; the point is epistemic, not semantic. I will argue that this remains a powerful challenge to metaphysics that has yet to be adequately answered. (shrink)
