This paper makes three points: First, empiricism as a stance is problematic unless criteria for evaluating the stance are provided. Second, Van Fraassen conceives of the empiricist stance as receiving its content, at least in part, from the rejection of metaphysics. But the rejection of metaphysics seems to presuppose for its justification the very empiricist doctrine Van Fraassen intends to replace with the empiricist stance. Third, while I agree with Van Fraassen’s endorsement of voluntarism, I raise doubts about the possibility of defending voluntarism without engaging in the kind of metaphysics Van Fraassen rejects.

Defeaters can prevent a perceptual belief from being justified. For example, when you know that red light is shining at the table before you, you would typically not be justified in believing that the table is red. However, can defeaters also destroy a perceptual experience as a source of justification? If the answer is ‘no’, the red light defeater blocks doxastic justification without destroying propositional justification. You have some-things-considered, but not all-things-considered, justification for believing that the table is red. If the answer is ‘yes’, the red light defeater blocks doxastic justification by destroying propositional justification. You have neither all-things-considered nor some-things-considered justification for believing that the table is red. According to dogmatism, the justificational force of perceptual experiences is indestructible. According to conservatism about sense experience, a perceptual experience ceases to have justificational force if there is evidence against its reliability. Finally, according to meta-evidentialism, a perceptual experience is blocked from being a source of justification is there is no evidence of its reliability. I argue that, of these three theories, meta-evidentialism is the most plausible.

I propose a version of foundationaUsm with the following distinctive features. First, it includes in the class of basic beliefs ordinary beliefs about physical objects. This makes it unrestricted. Second, it assigns the role of ultimate justifiers to A-states: states of being appeared to in various ways. Such states have propositional content, and are justifiers if they are presumptively reliable. The beliefs A-states justify are basic if they are non-inferential. In the last three sections of the paper, I defend this version of foundationalism against Sellars's famous anti-foundationalist dilemma, according to which sense-experiential states can't be justifiers ifthey lack propositional content, and can't terminate the justificatory regress if they have propositional content. I argue that the latter of these two claims is false. A-states can play the role of justifiers because they have propositional content, and they can terminate the justificatory regress because they themselves are capable of neither being true or false, nor being justified or unjustified.

When I take a sip from the coffee in my cup, I can taste that it is sweet. When I hold the cup with my hands, I can feel that it is hot. Why does the experience of feeling that the cup is hot give me justification for believing that the cup is hot?And why does the experience of tasting that the coffee is sweet give me justification for believing that the coffee is sweet?In general terms: Why is it that a sense experience that P is a source of justification—a reason—for believing that P? Call this the Question. I will discuss various answers to the Question, and defend the one I myself favor.

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification
