This chapter provides a survey of ontology in the analytic tradition with a special focus on the reasons for the reemergence of ontology in the 1970s. Beginning with the ontological views of Frege and Russell, the chapter discusses the origin of some central methodological tendencies in the tradition. The interplay between logical considerations and intuitive or common sense reasoning are discussed in detail. Some discussion of the anti-metaphysical views which figure prominently in the tradition are discussed. The chapter concludes by examining some recent developments.
