Two claims are essential to foundationalist theories of knowledge. First, that there are directly evident propositions; secondly, that, in justifying a particular knowledge claim, one ultimately arrives at a directly evident proposition making another proposition evident. In this dissertation, both claims are being defended. ;In defense of the first claim, a week definition of a proposition's being directly evident is suggested. Any attack against foundationalism rejecting the first claim must show that there are no contingent directly evident propositions in the sense of this definition. According to the thesis of privileged access, what a man believes about his mental states is directly evident, or, according to different versions of this thesis, self-presenting, infallible, self-evident, indubitable, or incorrigible. Rejecting a number of objections to it, the thesis of privileged access in all of its versions is being defended. In defense of the second claim, an account of prima facie evidence is set forth, incorporating definitions of the concepts "e tends to make h evident," "i defeats the evidence e provides for h," and "e makes h prima facie evident for S." It is claimed that, if a proposition p is made prima facie evident for a person S, then there is no ground on which it is reasonable for S to doubt that p is true. ;Furthermore, two epistemic principles are being offered. The first lays down the conditions under which evidence is generated, asserting that evidence is generated in virtue of a person's being in a psychological state. The second lays down the conditions under which evidence is transmitted from a directly to an indirectly evident proposition, asserting that evidence is transmitted from a directly to an indirectly evident proposition if the former bears to the latter the relation of "e making h prima facie evident."

Eleven pairs of newly commissioned essays face off on opposite sides of fundamental problems in current theories of knowledge. Brings together fresh debates on eleven of the most controversial issues in epistemology. Questions addressed include: Is knowledge contextual? Can skepticism be refuted? Can beliefs be justified through coherence alone? Is justified belief responsible belief? Lively debate format sharply defines the issues, and paves the way for further discussion. Will serve as an accessible introduction to the major topics in contemporary epistemology, whilst also capturing the imagination of professional philosophers.

Is it possible to argue that one’s memory is reliable without using one’s memory? I argue that it is not. Since it is not, it is impossible to defend the reliability ofone’s memory without employing reasoning that is epistemically circular. Hence, if epistemic circularity is vicious, it is impossible to succeed in producing a cogent argument for the reliability of one’s memory. The same applies to any other one of one’s cognitive faculties. I further argue that, if epistemic circularity is vicious, it is impossible to produce a cogent argument for the reliability of anything. For example, if epistemic circularity were vicious, a cogent argument for the reliability of one’s car would not be possible. The seeming viciousness of epistemic circularity even threatens, I propose, the possibility of justification and knowledge. Much, therefore, hangs one the question of whether epistemic circularity is indeed bad. I argue that epistemic circularity, or bootstrapping, need not be bad. When we use a crystal ball—a source perspicuously guilty of unreliability—to confirm its own reliability, bootstrapping is foolish. When we attribute reliability to a witness solely because the witness says he is reliable, bootstrapping is dogmatic. Foolish and dogmatic bootstrapping are bad. However, when a witness provides a rich body of testimony, using that testimony to gauge the witness’s reliability need not be a vicious form of circularity. When done critically, I argue, such reasoning exemplifies a form of bootstrapping that is benign.
