This chapter outlines the main themes of the essays that follow. It also occasionally corrects or clarifies them, and sometimes it discusses more recent literature than they do. One central theme is cognitive conditions and their contents. For example, is epistêmê knowledge as it is conceived of nowadays? Are doxa and dogma belief as it is conceived of nowadays? This chapter also asks whether Plato and/or Aristotle countenances some version of a Two Worlds Theory; and whether ancient skeptics countenance subjective states and/or external world skepticism. It also explains some key distinctions used throughout, such as that between concept and conception.
