The paper begins with a clarification of the notions of intuition (and, in particular, modal intuition), modal error, conceivability, metaphysical possibility, and epistemic possibility. It is argued that two-dimensionalism is the wrong framework for modal epistemology and that a certain nonreductionist approach to the theory of concepts and propositions is required instead. Finally, there is an examination of moderate rationalism’s impact on modal arguments in the philosophy of mind -- for example, Yablo’s disembodiment argument and Chalmers’s zombie argument. A (...) less vulnerable style of modal argument is defended, which nevertheless wins the same anti-materialist conclusions sought by these other arguments. (shrink)

Criticisms of Karl Popper’s critical rationalist epistemology are often confused and misleading. In part that is due to Popper’s somewhat lax use of language, in which technical terms are used in more than one sense. I attempt to clarify Popper’s views by regimenting his terminology. The result is offered as a clear and concise exposition of the main points of Popper’s epistemology. This is an updated version of a paper that was published in Cosmos + Taxis 6 (...) (6+7): 49-54 (2019). (shrink)

A very brief outline of Popper's methodology.

This collection highlights the new trend away from rationalism and toward empiricism in the epistemology of modality. Accordingly, the book represents a wide range of positions on the empirical sources of modal knowledge. Readers will find an introduction that surveys the field and provides a brief overview of the work, which progresses from empirically-sensitive rationalist accounts to fully empiricist accounts of modal knowledge. Early chapters focus on challenges to rationalist theories, essence-based approaches to modal knowledge, and the (...) prospects for naturalizing modal epistemology. The middle chapters present positive accounts that reject rationalism, but which stop short of advocating exclusive appeal to empirical sources of modal knowledge. The final chapters mark a transition toward exclusive reliance on empirical sources of modal knowledge. They explore ways of making similarity-based, analogical, inductive, and abductive arguments for modal claims based on empirical information. Modal epistemology is coming into its own as a field, and this book has the potential to anchor a new research agenda. (shrink)

Has the theory of rationality as ‘openness to criticism’ solved the problem of ‘rational belief in reason’? This is the main question the present article intends to address. I respond to this question by arguing that the justified true belief account of knowledge has prevented Karl Popper’s critical and William Bartley’s pan-critical rationalism from solving the problem of rational belief in reason. To elaborate this response, the article presents its arguments in three stages: First, it argues that the idea of (...) objective knowledge as justified true belief leads to the equation of objective knowledge with justification. Hence, if we base the theory of critical rationalism, as openness to criticism, upon such a conception of knowledge, our theory of rationality involves in infinite regress of proofs. Second, it argues that Popper describes critical rationalism as an ‘irrational attitude’ of openness to criticism because the rationalist cannot justify his belief in reason by argument or experience. Thus, since Popper assumes that ‘a belief in reason’ must be justified in order to be ‘rational’ he cannot lead to a solution for the problem of rational belief in reason. Third, it argues that, like Popper’s critical rationalism, Bartley’s pan-critical rationalism originates in the justified true belief account of knowledge, however, not because Bartley defines critical rationalism as irrational faith in reason, but because his theory does not tell us how an ‘open’ belief in reason is to be refuted logically. The reason for this failure is that Bartley uses Popper’s epistemology of science to define the conception of criticism. While Popper and Bartley are recognized as the non-justificationist philosophers of science and rationality, this article tries to reveal that the idea of objective knowledge as justified true belief has prevented them from showing how ‘a rational belief in reason’ can be defended by argument. The article also briefly shows the consequence of this study for a notable change in the logical foundations of science. (shrink)

This article evaluates Karl Popper's contribution to analytic philosophy, and outlines some of the contradictions in his work which make it difficult to locate in any particular tradition. In particular, the article investigates Popper's own claims to be a member of the rationalist tradition. Although Popper described himself as a member of this tradition, his definition of it diverged quite radically from that offered by other supporters of rationalism, like, for example, Mach, Carnap, and the logical positivists of the (...) Vienna Circle. The reason for this was that Popper believed the rationalist tradition, if it were to remain coherent and relevant, needed to overcome the dilemma posed by Hume's problem of induction. Popper believed that this problem rendered conventional understandings of rationalism, science, and inductive reasoning incoherent. This article suggests that Popper's principal contribution to modern philosophy was to reconfigure the rationalist tradition in such a way as to circumvent the problem of induction while preserving the rationalist commitment to reason, rational debate, and objective knowledge. Popper's reconfiguration of the epistemological bases of the rationalist tradition challenged dominant understandings of rationalist and analytic philosophy, and may be appropriately understood as part of a wider move among philosophers like Quine and Putnam to challenge conventional understandings of analytic philosophy, and of what philosophy itself could and could not achieve. It also informed a vision of social and political life (and of the social and political sciences) as rooted in principles of freedom, equality, and rational debate, but which cannot be fit within the traditional ideological landscape.

This paper takes up an important epistemological challenge to the naturalistic moral realist: that her metaphysical commitments are difficult to square with a plausible rationalist view about the epistemology of morality. The paper begins by clarifying and generalizing this challenge. It then illustrates how the generalized challenge can be answered by a form of naturalistic moral realism that I dub joint-carving moral realism. Both my framing of this challenge and my answer advertise the methodological significance of non-fundamental epistemological (...) theorizing, which defends and deploys epistemological claims without adverting to the most fundamental epistemological facts.

In this paper I argue against rationalist readings of Aristotle's epistemology, on which our scientific understanding is justified on the basis of certain demonstrative first principles that are themselves justified only by some brute form of rational intuition. I then investigate the relationship between our intuition of principles and the broadly perceptual knowledge from which it derives. I argue that, for Aristotle, perceptual knowledge helps justify our intuition of principles, and also serves as an authority against which these (...) principles and their consequences must be assessed. I end by considering how we should understand the justificatory role played by perception, and sketching the nuanced, empirically-minded sort of foundationalism I take Aristotle to endorse. (shrink)

This chapter introduces the rationalist model of delusions. It begins by presenting John Campbell’s seminal proposal that delusions are caused top-down by pathological Wittgensteinian framework or hinge beliefs. After presenting Campbell’s rationalist account of delusions, the chapter raises and examines prominent objections by Tim Bayne & Elisabeth Pacherie as well as by Tim Thornton. The former make an important distinction between the aetiological top-down cognitive part and the epistemological rationalist framework part of Campbell’s account. The thesis that (...) delusions are caused top-down by pathological beliefs is not equivalent to the thesis that delusions are Wittgensteinian framework certainties. This chapter endorses this distinction. While the arguments against the top-down aspect are found to be more convincing – which motivates popular two-factor theories – the rationalist framework model of delusions is defended as an epistemologically promising account of delusion. Finally, this chapter examines a range of developments that have been made taking Campbell’s rationalism as a starting point. Most prominently the section examines Eilan’s early development of rationalism and Rhodes and Gipps’ proposal that delusions are not framework propositions but a product of their absence. (shrink)

In this paper, I discuss the main characteristics of the epistemology of modal rationalism by proceeding from the critical investigation of Peacocke’s theory of modality. I build on arguments by Crispin Wright and Sonia Roca-Royes, which are generalised and supplemented by further analysis, in order to show that principle-based accounts have little prospects of succeeding in their task of providing an integrated account of the metaphysics and the epistemology of modality. I argue that it is unlikely that we (...) will able to develop an exhaustive and accurate principle-based account that discriminates objectively between correct and deviant modal knowledge. Even if such an account can be formulated, a non-circular way of justifying its necessity also seems to be out of our reach. (shrink)

"Certainty" occupies an important place in Wittgenstein’s epistemology: it does not belong to the category of knowledge but constitutes its foundation. In his view, knowledge boils down to language games, and language games are based on indubitable certainties. According to Wittgenstein, scepticism is meaningless, and if there is no certainty, then even doubt would be meaningless. Wittgesntein maintains that [relative] doubt and knowledge are epistemic categories, whereas absolute doubt and certainty are non-epistemic categories. Epistemic categories are meaningful and when (...) expressed by means of statements could be either true or false. In contrast, non-epistemic categories are meaningless and when expressed by means of statements the properties of truth and falsehood do not apply to them. The aim of the present paper is two fold: 1- Providing an explanation of the status of certainty in comparison to categories such as doubt and knowledge in Wittgenstein’s thought; 2- Providing a critical assessment of Wittgenstein's approach to certainty through the prism of critical rationalism. The main arguments of the paper are as follows: 1. Although Wittgenstein considers certainty to be meaningless and therefore not on a par with epistemological categories, he regards it as an objective concept that functions as the foundation upon which all human knowledge is based; 2. Wittgenstein's efforts to show the objectivity of certainty have not been entirely successful, partly due to his reliance on a defective notion of ‘objectivity’ and partly as a result of the prominence he assigns to the category of ‘meaning’ at the expense of the category of ‘truth’.

David Miller elegantly and provocatively reformulates critical rationalism—the revolutionary approach to epistemology advocated by Karl Popper—by answering its most important critics. He argues for an approach to rationality freed from the debilitating authoritarian dependence on reasons and justification. "Miller presents a particularly useful and stimulating account of critical rationalism. His work is both interesting and controversial... of interest to anyone with concerns in epistemology or the philosophy of science." —Canadian Philosophical Reviews.

Rationalism, Platonism and God comprises three main papers on Descartes, Spinoza and Leibniz, with extensive responses. It provides a significant contribution to the exploration of the common ground of the great early-modern Rationalist theories, and an examination of the ways in which the mainstream Platonic tradition permeates these theories. -/- John Cottingham identifies characteristically Platonic themes in Descartes's cosmology and metaphysics, finding them associated with two distinct, even opposed attitudes to nature and the human condition, one ancient and 'contemplative', (...) the other modern and 'controlling'. He finds the same tension in Descartes's moral theory, and believes that it remains unresolved in present-day ethics. -/- Was Spinoza a Neoplatonist theist, critical Cartesian, or naturalistic materialist? Michael Ayers argues that he was all of these. Analysis of his system reveals how Spinoza employed Neoplatonist monism against Descartes's Platonist pluralism. Yet the terminology - like the physics - is Cartesian. And within this Platonic-Cartesian shell Spinoza developed a rigorously naturalistic metaphysics and even, Ayers claims, an effectually empiricist epistemology. -/- Robert Merrihew Adams focuses on the Rationalists' arguments for the Platonist, anti-Empiricist principle of 'the priority of the perfect', i.e. the principle that finite attributes are to be understood through corresponding perfections of God, rather than the reverse. He finds the given arguments unsatisfactory but stimulating, and offers a development of one of Leibniz's for consideration. -/- These papers receive informed and constructive criticism and development at the hands of, respectively, Douglas Hedley, Sarah Hutton and Maria Rosa Antognazza.

The aim of this paper is to consider whether critical rationalism has any ideas which could usefully be applied to the internet. Today we tend to take the internet for granted and it is easy to forget that it was only about two decades ago that it began to be used to any significant extent. Accordingly in section 1 of the paper, there is a brief consideration of the history of the internet. At first sight this makes it looks implausible (...) that any of Popper’s ideas could be applicable to the internet, since Popper died before the internet came into general use. However, section 2 argues that Popper’s theory of World 3 does apply very well to the internet. This application is significant because, as shown in section 3, it leads to the problem of misinformation, which is one of the most significant problems generated by the internet. In section 4 there is an attempt to solve this problem using ideas taken from Popper’s epistemology. It is argued that there should be changes in education designed to prepare students for the internet age. Teaching in the internet age should focus on presenting to the students not just the accepted theories but also the evidence on which they are based. An illustration of how this might be done is given by considering an example from science teaching, namely the teaching of Newtonian mechanics in the last years of school or first years of university.

Modal rationalism includes the thesis that ideal primary positive conceivability entails primary possibility. Modal monism is the thesis that the space of logically possible worlds is coextensive with the space of metaphysically possible worlds. In this paper I explore the relation between the two theses. My aim is to show that the former thesis implies the latter thesis, and that problems with the latter make the former implausible as a complete picture of the epistemology of modality. My argument explores (...) the relation between logical modality and metaphysical modality. (shrink)

This book brings together thirteen articles on the most discussed thinkers in the rationalist movement: Descartes, Spinoza, Leibniz, and Malebranche. These articles address the topics in metaphysics and epistemology that figure most prominently in contemporary work on these philosophers. The articles have all been produced since 1980, and their authors are among the most respected in the field.

In _Realistic Rationalism_, Jerrold J. Katz develops a new philosophical position integrating realism and rationalism. Realism here means that the objects of study in mathematics and other formal sciences are abstract; rationalism means that our knowledge of them is not empirical. Katz uses this position to meet the principal challenges to realism. In exposing the flaws in criticisms of the antirealists, he shows that realists can explain knowledge of abstract objects without supposing we have causal contact with them, that numbers (...) are determinate objects, and that the standard counterexamples to the abstract/concrete distinction have no force. Generalizing the account of knowledge used to meet the challenges to realism, he develops a rationalist and non-naturalist account of philosophical knowledge and argues that it is preferable to contemporary naturalist and empiricist accounts. The book illuminates a wide range of philosophical issues, including the nature of necessity, the distinction between the formal and natural sciences, empiricist holism, the structure of ontology, and philosophical skepticism. Philosophers will use this fresh treatment of realism and rationalism as a starting point for new directions in their own research. (shrink)

Thirty years after the rise of the evidence-based medicine (EBM) movement, formal training in philosophy remains poorly represented among medical students and their educators. In this paper, I argue that EBM’s reception in this context has resulted in a privileging of empiricism over rationalism in clinical reasoning with unintended consequences for medical practice. After a limited review of the history of medical epistemology, I argue that a solution to this problem can be found in the method of the 2nd-century (...) Roman physician Galen, who brought empiricism and rationalism together in a synthesis anticipating the scientific method. Next, I review several of the problems that have been identified as resulting from a staunch commitment to empiricism in medical practice. Finally, I conclude that greater epistemological awareness in the medical community would precipitate a Galenic shift toward a more epistemically balanced, scientific approach to clinical research.

Jerrold Katz develops a new philosophical position integrating realism and rationalism.

It is commonly held that our intuitive judgements about imaginary problem cases are justified a priori, if and when they are justified at all. In this paper I defend this view — ‘rationalism’ — against a recent objection by Timothy Williamson. I argue that his objection fails on multiple grounds, but the reasons why it fails are instructive. Williamson argues from a claim about the semantics of intuitive judgements, to a claim about their psychological underpinnings, to the denial of rationalism. (...) I argue that the psychological claim — that a capacity for mental simulation explains our intuitive judgements — does not, even if true, provide reasons to reject rationalism. (More generally, a simulation hypothesis, about any category of judgements, is very limited in its epistemological implications: it is pitched at a level of explanation that is insensitive to central epistemic distinctions.) I also argue that Williamson’s semantic claim — that intuitive judgements are judgements of counterfactuals — is mistaken; rather, I propose, they are a certain kind of metaphysical possibility judgement. Several other competing proposals are also examined and criticized. (shrink)

Many epistemologists argue that responses to disagreement should exhibit a certain kind of epistemic impartiality. “Strong conciliationists” claim that we ought to give equal weight to the views of those who, judged from a dispute-neutral perspective, appear to be our “epistemic peers” with respect to some disputed matter. Using a Bayesian framework, Chapter 8 considers whether there is a plausible epistemic impartiality principle that would require us to give up confident religious (or irreligious) belief in favor of religious skepticism. It (...) is argued that the strong conciliationist’s epistemic impartiality is untenable, at least in contexts like the religious domain where the primary questions under dispute cannot be cleanly separated from questions about what qualifications are needed to reliably assess those primary questions. The chapter recommends instead a rationalist view on which rational insight can sustain justified confidence even when impartial grounds are lacking. It closes by defending the “religious acceptability” of this rationalist epistemology. (shrink)

In Epistemic Two-Dimensional Semantics, David Chalmers seeks to develop a version of 2-D semantics which can vindicate the rationalist claim that there are constitutive connections between meaning, possibility and a priority. Chalmers lays out different ways of filling in his preferred epistemic approach to 2-D semantics so as to avoid controversial philosophical assumptions. In these comments, however, I argue that there are some distinctively rationalist commitments in Chalmers's epistemic approach to 2-D semantics. I start by explaining why Chalmers's (...) approach requires a canonical language that affords subjects accurate a priori access to the space of possibility. I then argue that traditional worries about rationalism will simply re-emerge as worries about whether there can be a canonical vocabulary and how we could come to recognize one if there were. The moral is that Chalmers's 2-D semantic framework builds in substantive metaphysical and epistemological commitments which stand in need of further defense. (shrink)

This chapter compares rationalist theories of sense perception to previously held theories of perception (especially of vision) and examines rationalist accounts of sensory qualities and sensory representation, of the role of the sense-based passions in guiding behavior, of the epistemological benefits and dangers of sense perception, and of mind–body relations. Each section begins with Descartes, the first major rationalist of the seventeenth century. The other major rationalists, Malebranche, Spinoza, and Leibniz, and also lesser known figures such as (...) Pierre Regis, Jacques Rohault, and Antoine Le Grand, were well acquainted with Descartes' work. Indeed, the first three were each deeply influenced by Descartes in their early years before developing their own philosophical systems, and the latter three were all advocates of Descartes' philosophy (perhaps with slight revision). Each of the major rationalists, while sharing some positions in common, developed a distinctive metaphysics of perception and of the mind–body relation. Earlier sections chart these differences and a final section sums up common features and touches on the continuing significance of their views. (shrink)

‘Post-truth’ has become a buzzword for numerous current crises: the fragmentation of the media landscape, the ongoing debate about ‘fake news’, the loss of trust in science, etc. Although these crises take place in society, it is claimed that the roots of post-truth can be traced back to the history of philosophy. Occasionally, it is asserted that Karl Popper’s critical rationalism gave rise to post-truth: His rejection of verificationism has limited truth claims in the realm of science. Given the absence (...) of infallible evidence and certainty, critical rationalism calls for challenging scientific authority. I argue that post-truth is compatible with critical rationalism from an epistemological point of view, considering that both positions are critical of certainty. However, in critical rationalism, fallibilism, responsibility, and the idea of criticism are combined, and in this respect, it offers a possible way to overcome the problems that are associated with post-truth. This treatment of the problems of post-truth results from the recognition of moral responsibility to take action on the basis of a hypothesis that remains open to revision. (shrink)

Enquiries into the possible nature and scope of innate knowledge never proceed in an empirical vaccuum. Instead, such conjectures are informed by a theory (perhaps only tacitly endorsed) concerning probable representational form. Classical approaches to the nativism debate often assume a quasi-linguistic form of knowledge representation and deliniate a space of options (concerning the nature and extent of innate knowledge) accordingly. Recent connectionist theorizing posits a different kind of represenational form, and thus determines a different picture of the space of (...) possible nativisms. (shrink)

In this chapter, it is suggested that our epistemic access to metaphysical modality generally involves rationalist, a priori elements. However, these a priori elements are much more subtle than ‘traditional’ modal rationalism assumes. In fact, some might even question the ‘apriority’ of these elements, but I should stress that I consider a priori and a posteriori elements especially in our modal inquiry to be so deeply intertwined that it is not easy to tell them apart. Supposed metaphysically necessary identity (...) statements involving natural kind terms are a good example: the fact that empirical input is crucial in establishing their necessity has clouded the role and content of the a priori input, as I have previously argued. For instance, the supposed metaphysically necessary identity statement involving water and its microstructure can only be established with the help of a controversial a priori principle concerning the determination of chemical properties by microstructure. The Kripke-Putnam framework of modal epistemology fails precisely because it is unclear whether the required a priori element is present. My positive proposal builds on E. J. Lowe’s work. Lowe holds that our knowledge of metaphysical modality is based on our knowledge of essence. Lowe’s account strives to offer a uniform picture of modal epistemology: essence is the basis of all our modal knowledge. This is the basis of Lowe’s modal rationalism. I believe that Lowe’s proposal is on the right lines in the case of abstract objects, but I doubt that it can be successfully applied to the case of natural kinds. Accordingly, the case of natural kinds will be my main focus and I will suggest that modal rationalism, at least as it is traditionally understood, falls short of explaining modal knowledge concerning natural kinds. Yet, I think that Lowe has identified something of crucial importance for modal epistemology, namely the essentialist, a priori elements present in our modal inquiry. The upshot is that rather than moving all the way from modal rationalism to modal empiricism, a type of hybrid approach, ‘empirically-informed modal rationalism ’, can be developed. (shrink)

Popper’s Critical Rationalism presents Popper’s views on science, knowledge, and inquiry, and examines the significance and tenability of these in light of recent developments in philosophy of science, philosophy of probability, and epistemology. It develops a fresh and novel philosophical position on science, which employs key insights from Popper while rejecting other elements of his philosophy.

Engineering deals with different problem situations than science, and theories in engineering are different to theories in science. So, the growth of knowledge in engineering is also different to that in science. Nonetheless, methodological issues in engineering epistemology can be explored by adapting frameworks already established in the philosophy of science. In this paper I use critical rationalism and Popper’s three worlds framework to investigate error elimination and the growth of knowledge in engineering. I discuss engineering failure arising from (...) the falsification of engineering theories, and present taxonomies of the sources of falsification and responses to falsification in engineering. From this I discuss contexts of research and design in engineering, ad hoc rescue of engineering theories, and engineering assurance. (shrink)

Although Wes Shrum advertised my critics as representing quite distinct points of view, they nevertheless managed to converge on a set of concerns that revolve around the meanings of "rhetoric," "politics," and "multiculturalism" in the project of social epistemology. Either the critics were not chosen correctly or the book under discussion is quite obviously flawed! Rather than make that Hobson's choice, I will address my critics' concerns in a way that I hope will prove illuminating to other normatively oriented (...) theorists in the social sciences who want to take the challenge of postmodernism seriously but who also realize that postmodernism may soon become the orthodoxy, rather than the challenger, in cultural politics.

_Popper’s Critical Rationalism_ presents Popper’s views on science, knowledge, and inquiry, and examines the significance and tenability of these in light of recent developments in philosophy of science, philosophy of probability, and epistemology. It develops a fresh and novel philosophical position on science, which employs key insights from Popper while rejecting other elements of his philosophy. Central theses include: Crucial questions about scientific method arise at the level of the group, rather than that of the individual. Although criticism is (...) vital for science, dogmatism is important too. Belief in scientific theories is permissible even in the absence of evidence in their favour. The aim of science is to eliminate false theories. Critical rationalism can be understood as a form of virtue epistemology. (shrink)

This chapter contains sections titled: Sense Perception as a Natural Process Metaphysical, Epistemological, and Functional Aspects of Perception Sense, Mind, and Knowledge in Seventeenth‐Century Rationalism.

In these comments I briefly discuss three aspects of the empiricist account of the epistemic role of experience that Anil Gupta develops in his Empiricism and Experience. First, I discuss the motivations Gupta offers for the claim that the given in experience should be regarded as reliable. Second, I discuss two different ways of conceiving of the epistemic significance of the phenomenology of experience. And third, I discuss whether Gupta's account is able to deliver the anti-skeptical results he intends it (...) to. I close by suggesting that, once fully fleshed out, Gupta's account is best understood in terms of the fusion of certain core ideas within both the empiricist and the rationalist traditions.

I present a case for a rapprochement between aspects of rationalism and scientific realism, by way of a general framework employing modal epistemology and elements of 2-dimensional semantics (2DS). My overall argument strategy is meta-inductive: The bulk of this paper establishes a “base case,” i.e., a concretely constructive example by which I demonstrate this linkage. The base case or constructive example acts as the exemplar for generating, in a constructively ‘bottom-up’ fashion, a more generally rigorous case for rationalism-realism qua (...) modal epistemology. The exemple I choose in D. Chalmers’ (2002) modal rationalism and R. Giere’s (1985, 1988) constructive realism. I show by way of a thorough analysis how Giere’s claims concerning modal scope are characterized as instances of Chalmers’ modal rationalism, both weak and strong. In essence, as I demonstrate via Chalmers’ notions, ceteris paribus the constructive realist ultimately opts for a comparatively wider gate, characterized by modal reasoning, to lead from the rooms of conceivability qua thought experiments and models, to the pastures of metaphysical possibility. Chalmers likewise tries to erect such a wider gate, in his general conceivability-possibility theses. Anti-realists, on the other hand, see a narrower passage and my contention herein is that they suffer from modal myopia, which hopefully the ‘corrective vision’ of Chalmers’ modal rationalism can restore. In the introduction and concluding sections I sketch out suggestions of constructing ‘inductive steps’ from my base case, to generate more extensively general claims regarding realism qua rationalism. -/- .

This paper is about three of the most prominent debates in modern epistemology. The conclusion is that three prima facie appealing positions in these debates cannot be held simultaneously. The first debate is scepticism vs anti-scepticism. My conclusions apply to most kinds of debates between sceptics and their opponents, but I will focus on the inductive sceptic, who claims we cannot come to know what will happen in the future by induction. This is a fairly weak kind of scepticism, (...) and I suspect many philosophers who are generally anti-sceptical are attracted by this kind of scepticism. Still, even this kind of scepticism is quite unintuitive. I’m pretty sure I know (1) on the basis of induction. (1) It will snow in Ithaca next winter. Although I am taking a very strong version of anti-scepticism to be intuitively true here, the points I make will generalise to most other versions of scepticism. (Focussing on the inductive sceptic avoids some potential complications that I will note as they arise.) The second debate is a version of rationalism vs empiricism. The kind of rationalist I have in mind accepts that some deeply contingent propositions can be known a priori, and the empiricist I have in mind denies this. Kripke showed that there are contingent propositions that can be known a priori. One example is Water is the watery stuff of our acquaintance. (‘Watery’ is David Chalmers’s nice term for the properties of water by which folk identify it.) All the examples Kripke gave are of propositions that are, to use Gareth Evans’s term, deeply necessary (Evans, 1979). It is a matter of controversy presently just how to analyse Evans’s concepts of deep necessity and contingency, but most of the controversies are over details that are not important right here. I’ll simply adopt Stephen Yablo’s recent suggestion: a proposition is deeply contingent if it could have turned out to be true, and could have turned out to be false (Yablo, 2002)1. Kripke did not provide examples of any deeply contingent propositions knowable a priori, though nothing he showed rules out their existence.. (shrink)

One of the liveliest areas in moral psychology in recent years has been research on the extent to which conscious reasoning leads to the formation of moral judgments. The goal of this chapter is to review and briefly assess three of the leading positions today on this topic - traditional rationalism, social intuitionism, and morphological rationalism - each of which has significant implications for moral epistemology.

The expression “continental rationalism” refers to a set of views more or less shared by a number of philosophers active on the European continent during the latter two thirds of the seventeenth century and the beginning of the eighteenth. Rationalism is most often characterized as an epistemological position. On this view, to be a rationalist requires at least one of the following: (1) a privileging of reason and intuition over sensation and experience, (2) regarding all or most ideas as (...) innate rather than adventitious, (3) an emphasis on certain rather than merely probable knowledge as the goal of enquiry. While all of the continental rationalists meet one or more of these criteria, this is arguably the consequence of a deeper tie that binds them together—that is, a metaphysical commitment to the reality of substance, and, in particular, to substance as an underlying principle of unity.

In his book, Disagreement, Deference, and Religious Commitment, John Pittard presents and critiques what he calls the “master argument for disagreement-motivated religious skepticism.” This argument purports to show, using only higher-order reasoning and facts about religious disagreement, that nobody’s religious outlook is justified (at least, nobody aware of the argument). The master argument presupposes that any attempt to vindicate one’s religious outlook must employ dispute-independent reasons. Pittard objects to this assumption and argues, instead, for rationalist weak conciliationism: the view (...) that partisan justification can be had when (and only when) one has rational insight into the claim in question. In this paper, I raise a challenge for rationalist weak conciliationism; in short, it is difficult to explain why only rational insight provides partisan justification while maintaining that a wide range of beliefs, including religious beliefs, can be justified in a partisan way.

In the last decade, the familiar problem of the regress of reasons has returned to prominent consideration in epistemology. And with the return of the problem, evaluation of the options available for its solution is begun anew. Reason’s regress problem, roughly put, is that if one has good reasons to believe something, one must have good reason to hold those reasons are good. And for those reasons, one must have further reasons to hold they are good, and so a (...) regress of reasons looms. In this new study, Aikin presents a full case for infinitism as a response to the problem of the regress of reasons. Infinitism is the view that one must have a non-terminating chain of reasons in order to be justified. The most defensible form of infinitism, he argues, is that of a mixed theory – that is, epistemic infinitism must be consistent with and integrate other solutions to the regress problem. (shrink)

Several scholars have criticized the histories of early modern philosophy based on the dichotomy of empiricism and rationalism. They view them as overestimating the importance of epistemological issues for early modern philosophers (epistemological bias), portraying Kant's Critical philosophy as a superior alternative to empiricism and rationalism (Kantian bias), and forcing most or all early modern thinkers prior to Kant into the empiricist or rationalist camps (classificatory bias). Kant is often said to be the source of the three biases. Against (...) this criticism, this paper argues that Kant did not have the three biases. However, he promoted a way of writing histories of philosophy from which those biases would naturally flow. (shrink)
