The Foreword to the First Edition of Introduction to Objectivist Epistemology begins like this:
(1) This series of articles is presented by ‘popular demand.’ (2) We have had so many requests for information on Objectivist epistemology that I decided to put on record a summary of one of its cardinal elements—the Objectivist theory of concepts. (3) These articles may be regarded as a preview of my future book on Objectivism, and are offered here for the guidance of philosophy students (p. 1).
Each sentence here—in fact, each clause—tells us something significant about the content of “Objectivism.” I’ve added the reference numbers.
