‘The Routledge Philosophy Companions series has a deserved reputation for impressive scope and scholarly value. This volume is no exception … The editors successfully assemble chapters most relevant to contemporary work in metaphysics, a welcome trend in reference works for the 21st century. Summing Up: Highly recommended. All academic libraries supporting lower-level undergraduates and above.’ - Choice‘The field of metaphysics is flourishing - and with an outstanding cast of contributors, the impressively-broad and satisfyingly-deep Routledge Companion to Metaphysics offers a superb guide to many of its most engaging and perplexing twists and turns, both historical and contemporary.’ - Hud Hudson, Western Washington University, USA‘The Routledge Companion to Metaphysics promises to provide an accessible and historically informed survey of the field. It features over fifty articles, by some of the most prominent contemporary metaphysicians, covering virtually every major topic. Its combination of historical sweep and intellectual breadth set it apart from anything else on the market.’ - Jonathan Schaffer, Australian National University, Australia ‘This monumental volume presents a lively, up-to-date and extremely rich panorama of the present state of metaphysical debate. The 53 fully cross-referenced contributions are both admirably clear and deeply illuminating. It is difficult to imagine anything more useful for a course in metaphysics. This is bound to become a reference work for all scholars and students interested in metaphysics.’ - Andrea Bottani, Bergamo University, Italy
