How should one react when one has a belief, but knows that other people—who have roughly the same evidence as one has, and seem roughly as likely to react to it correctly—disagree? This paper argues that the disagreement of other competent inquirers often requires one to be much less confident in one’s opinions than one would otherwise be.

It is sometimes suggested that there are two kinds of reasoning: inferential reasoning and non-inferential reasoning. However, it is not entirely clear what the difference between these two kinds of reasoning is. In this paper, I try to answer the question what this difference is. I first discuss three answers to this question that I argue are unsatisfactory. I then give a different answer to this question, and I argue that this answer is satisfactory. I end by showing that this (...) answer can help to resolve some disagreements in which the difference between inferential and noninferential reasoning plays a role. (shrink)

It is a commonplace belief that many beliefs, e.g. religious convictions, are a purely private matter, and this is meant in some way to serve as a defense against certain forms of criticism. In this paper it is argued that this thesis is false, and that belief is really often a public matter. This argument, the publicity of belief argument, depends on one of the most compelling and central thesis of Peircean pragmatism. This crucial thesis is that bona fide belief (...) cannot be separated from action. It is then also suggested that we should accept a form of W. K. Clifford's evidentialism. When these theses are jointly accepted in conjunction with the basic principle of ethics that it is prima facie wrong to act in such a way that may subject others to serious but unnecessary and avoidable harm, it follows that many beliefs are morally wrong.

Reformed epistemology, roughly, is the thesis that religious belief can be rational without argument. After providing some background, I present Plantinga’s defense of reformed epistemology and its influence on religious debunking arguments. I then discuss three objections to Plantinga’s arguments that arise from the following topics: skeptical theism, cognitive science of religion, and basicality. I then show how reformed epistemology has recently been undergirded by a number of epistemological theories, including phenomenal conservatism and virtue epistemology. I end by noting that (...) a good objection to reformed epistemology must criticize either a substantive epistemological theory or the application of that theory to religious belief; I also show that the famous Great Pumpkin Objection is an example of the former.

This paper defends the view that philosophical propositions are merely relatively true, i.e. true relative to a doxastic perspective defined at least in part by a non-inferential belief-acquiring method. Here is the strategy: first, the primary way that contemporary philosophers defend their views is through the use of rational intuition, and this method delivers non-inferential, basic beliefs which are then systematized and brought into reflective equilibrium. Second, Christian theologians use exactly the same methodology, only replacing intuition with revelation. Third, intuition (...) and revelation yield frequently inconsistent output beliefs. Fourth, there is no defensible reason to prefer the dictates of intuition to those of Christian revelation. Fifth, the resulting dilemma means that there are true philosophical propositions, but we can't know them (scepticism), or there are no philosophical propositions and the naturalists are right (nihilism), or relativism is true. I suggest that relativism is the most palatable of these alternatives. (shrink)

Resolving religious disagreements is difficult, for beliefs about religion tend to come with strong biases against other views and the people who hold them. Evidence can help, but there is no agreed-upon policy for weighting it, and moreover bias affects the content of our evidence itself. Another complicating factor is that some biases are reliable and others unreliable. What we need is an evidence-weighting policy geared toward negotiating the effects of bias. I consider three evidence-weighting policies in the philosophy of (...) religion and advocate one of them as the best for promoting the resolution of religious disagreements. (shrink)

Thomas Aquinas has long been understood to have reconciled faith and reason. Typically, he is understood as having provided justification for faith by means of proof, particularly, that the Five Ways prove the existence of God. Under this interpretation, faith becomes a species of justified belief, and the justification for faith rests upon the success of the Five Ways . In this dissertation, I argue that Aquinas' account of faith is not one of justified belief, at least as it is (...) understood in contemporary philosophy. Instead, I argue, faith has its own basis for epistemic "reasonableness"---a reasonableness that does not derive from ordinary evidence nor proof. Rather than requiring evidence accessible to the natural light of reason, Aquinas holds that faith has its own sort of "evidence"---that which results from the light of faith. Aquinas "Aristotelianizes" faith and argues that faith has the Aristotelian epistemic virtue of certitude, and in so doing reconciles faith and Aristotelian reason, at least as Aristotle was understood by Medieval philosophers. This reconciliation resolves important tensions between Aristotelian science and Christian doctrine. Further, I examine three contemporary accounts of what counts as an epistemically "responsible" belief and argue that under Aquinas' account, faith should be counted as rational, and in an important, though modified sense, as justified.

Belief is a familiar attitude: taking something to be the case or regarding it as true. But we are more confident in some of our beliefs than in others. For this reason, many epistemologists appeal to a second attitude, called credence, similar to a degree of confidence. This raises the question: how do belief and credence relate to each other? On a belief-first view, beliefs are more fundamental and credences are a species of beliefs, e.g. beliefs about probabilities. On a (...) credence-first view, credences are more fundamental and beliefs are a species of credence, e.g. credence above some threshold. In this thesis, I develop and defend a third view that I call belief-credence dualism. On this view, belief and credence are independent, equally fundamental attitudes, and neither reduces to the other. I begin by motivating the project: why should we care about the relationship between belief and credence? I argue it has broad implications for many debates in epistemology and beyond. Then, I defend dualism, arguing that it can explain features of our mental lives that a credence-first view and a belief-first view cannot. I also argue that dualism has attractive, interesting implications when applied to the pragmatic encroachment debate. Finally, I explore implications of dualism, both for the nature of evidence and how faith might go beyond the evidence but nonetheless be epistemically rational. I conclude that the human mind is, in some ways, complex, but we should be happy with this conclusion also long as each mental state we posit has a clear role to play. (shrink)
