The paper deals with a version of the principle that a belief source can be a knowledge source only if the subject knows that it is reliable. I argue that the principle can be saved from the main objections that motivate its widespread rejection: the claim that it leads to skepticism, the claim that it forces us to accept counterintuitive knowledge ascriptions and the claim that it is incompatible with reliabilist accounts of knowledge. I argue that naturalist epistemologists should reject (...) these claims. I introduce my treatment of the principle by considering the analogous situation posed by the closure principle. (shrink)

Internalism restricts justifiers to what is "within" the subject. two main forms of internalism are (1) perspectival internalism (pi), which restricts justifiers to what the subject knows or justifiably believes, and (2) access internalism (ai), which restricts justifiers to what is directly accessible to the subject. the two forms are analyzed and interrelated, and the grounds for each are examined. it is concluded that although pi is both unacceptable and without adequate support, a modest form of ai might be defended.

This paper defends the view that a belief to the effect that the believer is currently in some conscious state is "self-Warranted," in the sense that what warrants it is simply its being a belief of that sort. This position is compared with other views as to the epistemic status of such beliefs--That they are warranted by their truth and that they are warranted by an immediate awareness of their object. In the course of the discussion, Various modes of immediate (...) justification and various types of "epistemic immunities" are distinguished. It is contended that principles of justification are to be evaluated in terms of whether the beliefs they approve are likely to be correct. (shrink)
