Abstract

This chapter argues for the replacement of the relevant alternatives account of perceptual knowledge with two-tiered view that is cast along the same lines. This two-tiered relevant alternatives theory is very much in accord with commonsense; conforms to the basic thought that underlies the core relevant alternatives intuition, which is that one can have knowledge without having to rule out far-fetched error-possibilities; and accommodates the thought that alternatives can be made relevant in other ways than by one's environment, though it does so in such a way as to keep the demands on our discriminative powers realistic.
