Designed for students of philosophy who have already done an introductory course in the subject, this volume aims to introduce the main topics of metaphysics while avoiding jargon and technicalities. Topics include the problem of universals, the nature of abstract entries, the problem of individuation, the nature of modality, identity through time, the nature of time, and the realism/antirealism debate. Where possible, the author attempts to relate contemporary views to their classical sources in the history of philosophy.
