ABSTRACT
This chapter deals with two topics of fundamental importance for theory of knowledge. It explains what the author means by "the problem of the criterion." The chapter argues that one of the tasks of the epistemologist is to find and formulate criteria for the application of epistemic terms such as "evidence" and "knowledge," just as the moral philosopher must try to discover right-making characteristics, wrong-making characteristics, goodmaking characteristics, etc., which are criteria for the application of ethical terms. It formulates a criterion of "appearing" which seems to be characteristic of empiricism in one of its traditional forms, and then argues that this criterion must be supplemented by a criterion of perceptual "taking." The chapter explains the grounds of the author's disagreement in a useful way.
