In this paper I develop a novel challenge for sceptical theists. I present a line of reasoning that appeals to sceptical theism to support scepticism about divine assertions. I claim that this reasoning is at least as plausible as one popular sceptical theistic strategy for responding to evidential arguments from evil. Thus, I seek to impale sceptical theists on the horns of a dilemma: concede that either sceptical theism implies scepticism about divine assertions, or the sceptical theistic strategy for responding (...) to evidential arguments from evil fails. An implication of is that sceptical theism is at odds with any religious tradition according to which there are certain claims that we can know to be true solely in virtue of the fact that God has told us that they are true. This result will render conceding unattractive to many sceptical theists. (shrink)

Evolutionary debunkers of morality hold this thesis: If S’s moral belief that P can be given an evolutionary explanation, then S’s moral belief that P is not knowledge. In this paper, I debunk a variety of arguments for this thesis. I first sketch a possible evolutionary explanation for some human moral beliefs. Next, I explain how, given a reliabilist approach to warrant, my account implies that humans possess moral knowledge. Finally, I examine the debunking arguments of Michael Ruse, Sharon Street, (...) and Richard Joyce. I draw on the account of moral knowledge sketched earlier to illustrate how these arguments fail. -/- . (shrink)

Suppose there is no God. This might imply that human life is meaningless, that there are no moral obligations and hence people can do whatever they want, and that the notions of virtue and vice and good and evil have no place. Erik J. Wielenberg believes this view to be mistaken and in this book he explains why. He argues that even if God does not exist, human life can have meaning, we do have moral obligations, and virtue is (...) possible. Naturally, the author sees virtue in a Godless universe as different from virtue in a Christian universe, and he develops naturalistic accounts of humility, charity, and hope. The moral landscape in a Godless universe is different from the moral landscape in a Christian universe, but it does indeed exist. Value and Virtue in a Godless Universe is a tour of some of the central landmarks of this under-explored territory. (shrink)

It is tempting to think that, if a person's beliefs are coherent, they are also likely to be true. This truth conduciveness claim is the cornerstone of the popular coherence theory of knowledge and justification. Erik Olsson's new book is the most extensive and detailed study of coherence and probable truth to date. Setting new standards of precision and clarity, Olsson argues that the value of coherence has been widely overestimated. Provocative and readable, Against Coherence will make stimulating reading (...) for epistemologists and anyone with a serious interest in truth. (shrink)

Many believe that objective morality requires a theistic foundation. I maintain that there are sui generis objective ethical facts that do not reduce to natural or supernatural facts. On my view, objective morality does not require an external foundation of any kind. After explaining my view, I defend it against a variety of objections posed by William Wainwright, William Lane Craig, and J. P. Moreland.

One of the cornerstones of western theology is the doctrine of divine omnipotence. God is traditionally conceived of as an omnipotent or all-powerful being. However, satisfactory analyses of omnipotence are notoriously elusive. In this paper, I first consider some simple attempts to analyze omnipotence, showing how each fails. I then consider two more sophisticated accounts of omnipotence. The first of these is presented by Edward Wierenga; the second by Thomas Flint and Alfred Freddoso. I argue that both of these accounts (...) fail. Finally, I propose and defend a novel account of omnipotence. (shrink)

In a seminal book, Alvin I. Goldman outlines a theory for how to evaluate social practices with respect to their “veritistic value”, i.e., their tendency to promote the acquisition of true beliefs in society. In the same work, Goldman raises a number of serious worries for his account. Two of them concern the possibility of determining the veritistic value of a practice in a concrete case because we often don't know what beliefs are actually true, and even if we did, (...) the task of determining the veritistic value would be computationally extremely difficult. Neither problem is specific to Goldman's theory and both can be expected to arise for just about any account of veritistic value. It is argued here that the first problem does not pose a serious threat to large classes of interesting practices. The bulk of the paper is devoted to the computational problem, which, it is submitted, can be addressed in promising terms by means of computer simulation. In an attempt to add vividness to this proposal, an up-and-running simulation environment is presented and put to some preliminary tests. (shrink)

I challenge a cornerstone of the Gettier debate: that a proposed analysis of the concept of knowledge is inadequate unless it entails that people don’t know in Gettier cases. I do so from the perspective of Carnap’s methodology of explication. It turns out that the Gettier problem per se is not a fatal problem for any account of knowledge, thus understood. It all depends on how the account fares regarding other putative counter examples and the further Carnapian desiderata of exactness, (...) fruitfulness and simplicity. Carnap proposed his methodology more than a decade before Gettier’s seminal paper appeared, making the present solution to the problem a candidate for being the least ad hoc proposal on the market, one whose independent standing cannot be questioned, among solutions that depart from the usual method of revising a theory of knowledge in the light of counterexamples. As an illustration of the method at work, I reconstruct reliabilism as an attempt to provide an explication of the concept of knowledge. (shrink)

The standard way of representing an epistemic state in formal philosophy is in terms of a set of sentences, corresponding to the agent’s beliefs, and an ordering of those sentences, reflecting how well entrenched they are in the agent’s epistemic state. We argue that this wide-spread representational view – a view that we identify as a “Quinean dogma” – is incapable of making certain crucial distinctions. We propose, as a remedy, that any adequate representation of epistemic states must also include (...) the agent’s research agenda, i.e., the list of question that are open or closed at any given point in time. If the argument of the paper is sound, a person’s questions and practical interests, on the one hand, and her beliefs and theoretical values, on the other, are more tightly interwoven than has previously been assumed to be the case in formal epistemology.

Epistemologists can be divided into two camps: those who think that nothing short of certainty or (subjective) probability 1 can warrant assertion and those who disagree with this claim. This paper addressed this issue by inquiring into the problem of setting the probability threshold required for assertion in such a way that that the social epistemic good is maximized, where the latter is taken to be the veritistic value in the sense of Goldman (Knowledge in a social world, 1999). We (...) provide a Bayesian model of a test case involving a community of inquirers in a social network engaged in group deliberation regarding the truth or falsity of a proposition $p.$ p . Results obtained by means of computer simulation indicate that the certainty rule is optimal in the limit of inquiry and communication but that a lower threshold is preferable in less idealized cases.

I present a novel argument for the position that a morally unsurpassable God must create the best world that He has the power to create. I show that grace-based considerations of the sort proposed by Robert Adams neither refute my argument nor establish that a morally unsurpassable God need not create the best. I conclude with a discussion of the implications of my argument for the ‘no-best-world’ response to the problem of evil. (Published Online February 17 2004).

This article redescribes early modern European defenses of private property in terms of a theoretical project of seeking to establish the true or essential nature of property. Most of the scholarly literature has focused on the historical and normative issues relating to the various accounts of original acquisition around which these defenses were organized. However, in my redescription, these so-called “original acquisition stories” appear as methodological devices for an analytic reduction and resolution of property into its fundamental elements and axioms. (...) Through these stories, property is “created” in the form of the classical liberal paradigm of presumptively exclusive, private ownership of material things. The problem is that this project of “creation” is also a project which arbitrarily excludes or marginalizes other forms and systems of property, and especially usufructuary forms of common property. After critically explicating this early modern project of creation, I go on to argue that the classical liberal paradigm and its problems continue to inform property theory and discourse in the late modern era.

There is an emerging consensus in the literature on probabilistic coherence that such coherence cannot be truth conducive unless the information sources providing the cohering information are individually credible and collectively independent. Furthermore, coherence can at best be truth conducive in a ceteris paribus sense. Bovens and Hartmann have argued that there cannot be any measure of coherence that is truth conducive even in this very weak sense. In this paper, I give an alternative impossibility proof. I provide a relatively (...) detailed comparison of the two results, which turn out to be logically unrelated, and argue that my result answers a question raised by Bovens and Hartmann’s study. Finally, I discuss the epistemological ramifications of these findings and try to make plausible that a shift to an explanatory framework such as Thagard’s is unlikely to turn the impossibility into a possibility.

I draw on the literature on skeptical theism to develop an argument against Christian theism based on the widespread existence of suffering that appears to its sufferer to be gratuitous and is combined with the sense that God has abandoned one or never existed in the first place. While the core idea of the argument is hardly novel, key elements of the argument are importantly different from other influential arguments against Christian theism. After explaining that argument, I make the case (...) that the argument is untouched by traditional skeptical theism. I then consider positive skeptical theism, arguing that while DePoe’s view might provide a response to my argument, it entangles the theist in worries about divine deception. Because traditional skeptical theism and DePoe’s positive skeptical theism constitute the most promising extant strategies for answering my argument, the argument constitutes a serious challenge for the Christian theist. My overall aim, then, is to draw on various strands of the skeptical theism literature to present a challenge for all Christian theists, not just those in the skeptical theist camp, while at the same time revealing some important limitations of skeptical theism.

This chapter considers the present account to be a sufficient response to the generality problem as an objection that specifically targets reliabilism. It identifies the main challenge for reliabilism in relation to the typing of belief‐forming processes. The chapter focuses on insights in cognitive science in a way that should make this response attractive to practitioners of naturalized epistemology, including Goldman himself. The most stimulating part of Conee and Feldman's attack can charitably be viewed as targeting the notion that the (...) reliabilist concepts of knowledge and justification are sufficiently similar to their folk counterparts. The chapter focuses for simplicity on the reliabilist theory of justification (RJ) and on Conee and Feldman's criticism as targeting the faithfulness of RJ with regard to everyday concept of justification. For the purposes of neutralizing Conee and Feldman's central challenge it was sufficient to give a purely descriptive account of how people type belief‐forming processes. (shrink)

Gerald Harrison identifies two Euthyphro-related concerns for divine command theories and makes the case that to the extent that these concerns make trouble for divine command theories they also make trouble for non-naturalistic moral realism and naturalistic moral realism. He also offers responses to the two concerns on behalf of divine command theorists. I show here that the parity thesis does not hold for the most commonly discussed version of divine command theory. I further argue that his responses to the (...) two concerns fail. Finally, I draw on some of Harrison’s ideas to identify an advantage that non-naturalistic moral realism has over divine command theories and naturalistic moral realism. (shrink)

A measure of coherence is said to be truth conducive if and only if a higher degree of coherence (as measured) results in a higher likelihood of truth. Recent impossibility results strongly indicate that there are no (non-trivial) probabilistic coherence measures that are truth conducive. Indeed, this holds even if truth conduciveness is understood in a weak ceteris paribus sense (Bovens & Hartmann, 2003, Bayesian epistemology. New York, Oxford: Oxford University Press; Olsson, 2005, Against coherence: Truth probability and justification. Oxford: (...) Oxford University Press). This raises the problem of how coherence could nonetheless be an epistemically important property. Our proposal is that coherence may be linked in a certain way to reliability. We define a measure of coherence to be reliability conducive if and only if a higher degree of coherence (as measured) results in a higher probability that the information sources are reliable. Restricting ourselves to the most basic case, we investigate which coherence measures in the literature are reliability conducive. It turns out that, while a number of measures fail to be reliability conducive, except possibly in a trivial and uninteresting sense, Shogenji’s measure and several measures generated by Douven and Meijs’s recipe are notable exceptions to this rule.

A problem occupying much contemporary epistemology is that of explaining why knowledge is more valuable than mere true belief. This paper provides an overview of this debate, starting with historical figures and early work. The contemporary debate in mainstream epistemology is then surveyed and some recent developments that deserve special attention are highlighted, including mounting doubts about the prospects for virtue epistemology to solve the value problem as well as renewed interest in classical and reliabilist‐externalist responses.

In Robust Ethics, I defend a nontheistic version of moral realism according to which moral properties are sui generis, not reducible to other kinds of properties (e.g., natural properties or supernatural properties) and objective morality requires no foundation external to itself. I seek to provide a plausible account of the metaphysics and epistemology of the robust brand of moral realism I favor that draws on both analytic philosophy and contemporary empirical moral psychology. In this paper, I respond to some objections (...) to my view advanced by William Craig, Mark Murphy, Tyler McNabb, and Adam Johnson. (shrink)

Jonathan Cohen has claimed that in cases of witness agreement there is an inverse relationship between the prior probability and the posterior probability of what is being agreed: the posterior rises as the prior falls. As is demonstrated in this paper, this contention is not generally valid. In fact, in the most straightforward case exactly the opposite is true: a lower prior also means a lower posterior. This notwithstanding, there is a grain of truth to what Cohen is saying, as (...) there are special circumstances under which a thesis similar to his holds good. What characterises these circumstances is that they allow for the fact of agreement to be surprising. In making this precise, I draw on Paul Horwich's probabilistic analysis of surprise. I also consider a related claim made by Cohen concerning the effect of lowering the prior on the strength of corroboration. 1 Introduction 2 Cohen's claim 3 A counterexample 4 A weaker claim 5 A counterexample to the weaker claim 6 The grain of truth in Cohen's claim 7 Prior probability and strength of corroboration 8 Conclusion.

Juan Comesaña and Carolina Sartorio have recently proposed a diagnosis of what goes wrong in apparently illegitimate cases of ‘bootstrapping’ one’s way toexcessively easy knowledge. They argue that in such cases the bootstrapper bases at least one of her beliefs on evidence that does not evidentially support the proposition believed. I explicate the principle that underlies Comesaña and Sartorio’s diagnosis of such cases and show that their account of what goes wrong in such cases is mistaken.

I argue that William Craig’s defence of the moral argument is internally inconsistent. In the course of defending the moral argument, Craig criticizes non-theistic moral realism on the grounds that it posits the existence of certain logically necessary connections but fails to provide an adequate account of why such connections hold. Another component of Craig’s defence of the moral argument is an endorsement of a particular version of the divine command theory. Craig’s version of DCT posits certain logically necessary connections (...) but Craig fails to provide an adequate account of why these connections hold. Thus, Craig’s critique of non-theistic moral realism is at odds with his DCT. Since the critique and DCT are both essential elements of his defence of the moral argument, that defence is internally inconsistent. (shrink)

I argue that the analysis most capable of systematising our intuitions about coherence as a relation is one according to which a set of beliefs, A, coheres with another set, B, if and only if the set-theoretical union of A and B is a coherent set. The second problem I consider is the role of coherence in epistemic justification. I submit that there are severe problems pertaining to the idea, defended most prominently by Keith Lehrer, that justification amounts to coherence (...) with an acceptance system. Instead I advance a more dynamic approach according to which the problem of justification is the problem of how to merge new information with old coherently, a process which is seen to be closely connected with relational coherence.

Alvin Plantinga has famously argued that naturalism is self-defeating. Plantinga's argument is, at its heart, an argument from analogy. Plantinga presents various epistemic situations and claims of each that (i) a person in such a situation has an undefeated defeater for each of his beliefs, and (ii) a reflective naturalist is in a relevantly similar situation. I present various epistemic situations and claim of each that a person in such a situation does not have an undefeated defeater for each of (...) his beliefs. I further claim that at least some of these situations are more relevantly like the situation faced by the reflective naturalist than any of the situations Plantinga describes. Therefore, Plantinga's argument fails to establish that the reflective naturalist has an undefeated defeater for each of his beliefs and hence fails to establish that naturalism is self-defeating.

We reply to Christoph Jäger's criticism of the conditional probability solution (CPS) to the value problem for reliabilism due to Goldman and Olsson (2009). We argue that while Jäger raises some legitimate concerns about the compatibility of CPS with externalist epistemology, his objections do not in the end reduce the plausibility of that solution.

The main issue in the epistemology of peer disagreement is whether known disagreement among those who are in symmetrical epistemic positions undermines the rationality of their maintaining their respective views. Douven and Kelp have argued convincingly that this problem is best understood as being about how to respond to peer disagreement repeatedly over time, and that this diachronic issue can be best approached through computer simulation. However, Douven and Kelp’s favored simulation framework cannot naturally handle Christensen’s famous Mental Math example. (...) As a remedy, I introduce an alternative simulation framework, Laputa, inspired by Alvin Goldman’s seminal work on veritistic social epistemology. I show that Christensen’s conciliatory response, reasonably reconstructed and supplemented, gives rise to an increase in epistemic value only if the peers continue to recheck their mental math; else the peers might as well be steadfast. On a meta-level, the study illustrates the power of Goldman’s approach when combined with simulation techniques for handling the computational issues involved. (shrink)

Hans Rott has argued, most recently in his book Change, Choice and Inference, that certain formal correspondences between belief revision and rational choice have important philosophical implications, claiming that the former strongly indicate the unity of practical and theoretical reason as well as the primacy of practical reason.

My conclusion is that, while Rott's work is indisputable as a formal achievement, the philosophical consequences he wants to draw are not (...) forthcoming. (shrink)

The paper deals mainly with two problems in the epistemology of Frank Plumpton Ramsey. One concerns his account of knowledge, the other his fallibilism. I argue that Ramsey failed to make room for the social aspect of knowledge and, furthermore, that he did not separate the fallibility of our view from its corrigibility. My positive proposal is to combine social reliabilism and corrigibilism with a rejection of fallibilism.

_Kexue_, or science, captured the Chinese imagination in the early twentieth century, promising new knowledge about the world and a dynamic path to prosperity. Chinese Buddhists embraced scientific language and ideas to carve out a place for their religion within a rapidly modernizing society. Examining dozens of previously unstudied writings from the Chinese Buddhist press, this book maps Buddhists' efforts to rethink their traditions through science in the initial decades of the twentieth century. Buddhists believed science offered an exciting, alternative (...) route to knowledge grounded in empirical thought, much like their own. They encouraged young scholars to study subatomic and relativistic physics while still maintaining Buddhism's vital illumination of human nature and its crucial support of an ethical system rooted in radical egalitarianism. Showcasing the rich and progressive steps Chinese religious scholars took in adapting to science's rising authority, this volume offers a key perspective on how a major Eastern power transitioned to modernity in the twentieth century and how its intellectuals anticipated many of the ideas debated by scholars of science and Buddhism today.

My concern in this paper is a debate between Pascal Engel and Richard Rorty documented in the book What’s the Use of Truth? Both Engel and Rorty problematize the natural suggestion that attaining truth is a goal of our inquiries. Where Rorty thinks this means that truth is not something we should aim for at all over and beyond justification, Engel maintains that truth still plays a distinct role in our intellectual and daily lives. Thus, the debate between Engel and (...) Rorty ends in a standoff. In the present paper, I question the claim that truth is not a goal of inquiry. I do so from the point of view of a systematic and general theory of rational goal-setting which has its roots in management science. I argue, in this connection, that Rorty’s central claim rests on a principle of goal-setting rationality that is generally invalid. The bottom line is that the goal of truth, like other visionary goals, is likely to have the positive effect of increasing motivation and effort, and this may offset the drawbacks which Rorty, rightly, calls attention to. In largely following Rorty in this regard, Engel is making one concession too much to his opponent. (shrink)

According to the so?called swamping problem, reliabilist knowledge is no more valuable than mere true belief. In a paper called ?Reliabilism and the value of knowledge?
