This chapter aims to make Introduction to Objectivist Epistemology (ITOE) more accessible both to students of epistemology without a background in Objectivism and to students of Objectivism without a background in epistemology. It begins with a discussion of some figures and issues in the history of philosophy that helps to appreciate what Ayn Rand meant by the advocacy of reason and why she saw the issue of concepts as central to epistemology. The chapter then considers Rand view of consciousness and (...) sense perception, and also discusses her view of the process by which concepts and a whole system of conceptual knowledge are built upon a perceptual foundation. Next, it looks more closely at Rand's conception of objectivity and how it relates to her theory of concepts. Finally, the chapter considers the standards that follow from Rand's theory for the proper formation and use of concepts. (shrink)
