This book explores the Bayesian approach to the logic and epistemology of scientific reasoning. Section 1 introduces the probability calculus as an appealing generalization of classical logic for uncertain reasoning. Section 2 explores some of the vast terrain of Bayesian epistemology. Three epistemological postulates suggested by Thomas Bayes in his seminal work guide the exploration. This section discusses modern developments and defenses of these postulates as well as some important criticisms and complications that lie in wait for the Bayesian epistemologist. Section 3 applies the formal tools and principles of the first two sections to a handful of topics in the epistemology of scientific reasoning: confirmation, explanatory reasoning, evidential diversity and robustness analysis, hypothesis competition, and Ockham's Razor.

This book is a long-awaited major statement by a pre-eminent analytic philosopher, on one of our biggest debates—the compatibility of science and religion. The last twenty years has seen a cottage industry of books on this divide, but with little consensus emerging. This book's author, as a top philosopher but also a proponent of the rationality of religious belief, has a unique contribution to make. The theme of this short book is that the conflict between science and theistic religion is actually superficial, and that at a deeper level they are in concord. The book examines where this conflict is supposed to exist—evolution, evolutionary psychology, analysis of scripture, scientific study of religion—as well as claims by Dan Dennett, Richard Dawkins, and Philip Kitcher that evolution and theistic belief cannot co-exist. The book makes a case that their arguments are not only inconclusive but that the supposed conflicts themselves are superficial, due to the methodological naturalism used by science. On the other hand, science can actually offer support to theistic doctrines, and the text uses the notion of biological and cosmological “fine-tuning” in support of this idea. The book argues that we might think about arguments in science and religion in a new way—as different forms of discourse that try to persuade people to look at questions from a perspective such that they can see that something is true. In this way, there is a deep and massive consonance between theism and the scientific enterprise.

In this book's companion volumes (Warrant: The Current Debate and Warrant and Proper Function), I examined the nature of epistemic warrant, that quantity, enough of which distinguishes knowledge from mere true belief; in this book, I turn to the question of whether Christian belief can be justified, rational, and warranted. Among objections to Christian belief, we can distinguish between de facto objections and de jure objections, i.e., between those that claim that Christian belief is false (de facto objections) and those that claim that Christian belief, whether or not true, is at any rate unjustifiable, or rationally unjustified, or irrational, or not intellectually respectable, or in some other way rationally unacceptable (de jure objections). The main question of this book is the question of whether there are any viable de jure objections to Christian belief; I argue that there are not. In Part I (Chs. 1 and 2), I consider and address an initial objection to my project: the objection that there isn’t really any such thing as Christian belief (or at any rate that Christian belief is incoherent) since human concepts cannot apply to a transcendent God. In Part II, I explore, first, the question of whether a viable de jure objection to Christian belief can be developed in terms of justification or rationality (Chs. 3 and 4); after arguing for a negative answer to that question, I turn to the objections offered by Freud, Marx, and Nietzche, objections best understood as the claim that theistic and Christian belief lack warrant (Ch. 5). In Part III, Ch. 6, I address this claim, doing so by presenting a model of how it is that belief in God can have warrant, and even warrant sufficient for knowledge; I call this model the Aquinas/Calvin (or A/C) model, since it draws on the thought of Thomas Aquinas and John Calvin. In Ch. 7, I consider the noetic effects of sin, and the way in which the existence of sin throws a monkey wrench into the A/C model. In Chs. 8 and 9, I extend the A/C model in such a way as to deal both with sin and with the full panoply of Christian belief (trinity, incarnation, atonement, resurrection, etc.); the extended A/C model shows how full‐blooded Christian belief (not just theistic belief) can have warrant. After dealing with objections to the A/C model in Ch. 10, I turn in Part IV to potential or actual defeaters for Christian belief – possible reasons to give it up or hold it less firmly. The proposed defeaters I examine relate to projection theories of religious belief (Ch. 11), contemporary historical biblical criticism (Ch. 12), postmodernism and religious pluralism (Ch. 13), and the age‐old problem of evil (Ch. 14); none of these, I argue, presents a serious challenge to the warrant Christian belief can enjoy.
