It is nearly universally acknowledged among epistemologists that a belief, even if true, cannot count as knowledge if it is somehow largely a matter of luck that the person so arrived at the truth. A striking feature of this literature, however, is that while many epistemologists are busy arguing about which particular technical condition most effectively rules out the offensive presence of luck in true believing, almost no one is asking why it matters so much that knowledge be immune from luck in the first place. I argue that the best explanation for the consensus that luck undermines knowledge is that knowledge is, complications aside, credit-worthy true believing. To make this case, I develop both the notions of luck and credit, and sketch a theory of knowledge in those terms. Furthermore, this account also holds promise for being able to solve the “value problem” for knowledge, and it explains why both internal and external conditions are necessary to turn true belief into knowledge.

We commonly speak of people as being ‘‘justified’’ or ‘‘unjustified’’ in believing as they do. These terms describe a person’s epistemic condition. To be justified in believing as one does is to have a positive epistemic status in virtue of holding one’s belief in a way which fully satisfies the relevant epistemic requirements or norms. This requires something more (or other) than simply believing a proposition whose truth is well-supported by evidence, even by evidence which one possesses oneself, since one could entirely miss the relevance of this evidence and hold the belief as a result of wishful thinking or for some other bad reason. My topic in this paper is the notion of being justified which precludes beliefs flawed in this way. I will take the notion of something’s telling in favor of the truth of a proposition—that is, the notion of evidential support—for granted.

The first sentence in this essay is a lie. There is something odd about saying so, as has been known since ancient times. To see why, remember that all lies are untrue. Is the first sentence true? If it is, then it is a lie, and so it is not true. Conversely, suppose that it is not true. As we (viz., the authors) have said it, presumably with the intention of you believing it when it is not true, it is a lie. But then it is true!

The word 'belief' is ambiguous, referring sometimes to what is believed, sometimes to the act or state of believing it. I believe that as I write this it is sunny outside. This belief is true. What is true is what I believe, namely that it is sunny, not my believing it. On the other hand, my belief that it is sunny is rational and unshakeable, and it played a causal role in my deciding not to wear a coat today. What is rational, unshakeable, and played a causal role is my believing a certain thing, not the thing I believe. I will say that what I believe is an object of belief , and that my believing it is a belief state.

To believe a proposition wishfully is to believe it because one wants to believe it, and not because one has evidence or reason that it is true. Is it wise to be open to believing wishfully? After criticising one popular argument that we ought be closed to believing wishfully, I develop an argument that being closed to believing wishfully is to labour under a debilitating prejudice. As a rule, then, we ought to be open to believing wishfully. I find one and only one exception to this rule. People who value understanding things as they are, and value this more than anything else they value, are wise to be closed to believing wishfully.

I show that van Fraassen's empiricism leads to mutually incompatible claims with regard to empirical theories. He is committed to the claim that reasons for accepting a theory and believing it are always identical, insofar as the theory in question is an empirical theory. He also makes a general claim that reasons for accepting a theory are not always reasons for believing it irrespective of whether the theory is an empirical theory.

The paper considers Renee Descartes’ assertion that believing that God exists because the Bible says so, and believing that what the Bible says is true because God says it, involves circular reasoning. It argues that there is no circularity involved in holding these beliefs, and maintains that the appearance of circularity results from an equivocation. It considers a line of argument that would defend the rationality of holding these beliefs, but does not try to prove its soundness.

Belief is not a unified phenomenon. In this paper I argue, as a number of other riters argue, that one should distinguish a variety of belief-like attitudes: believing proper - a dispositional state which can have degrees - holding true - which can occur without understanding what one believes - and accepting - a practical and contextual attitude that has a role in deliberation and in practical reasoning. Acceptance itself is not a unified attitude. I explore the various relationships and differences between these doxastic attitudes, and claim that although acceptance is distinct from belief, it rests upon it, and is therefore a species of belief.
