Abstract

Many critics of Locke have worried that restricting knowledge to relationships among ideas would bar knowledge from extending to the outer reality which "corresponds to" these ideas. The question of how well Locke can answer such concerns leads us into a number of peculiar and intriguing passages on knowledge and the relationships between perception, reality, pain, and pleasure. This chapter examines what John Locke has to say about sensitive knowledge, to investigate several ways in which his remarks on this topic can be reconciled with what he says elsewhere. It also talks about the idea of sensation, and assesses the merits of Locke's conception of sensitive knowledge both as a response to skepticism and as a part of the larger picture of human understanding painted in the Essay. Two passages in the Essay describe sensitive knowledge in some detail, both beginning with a description of the skeptical problem.
