Many of your preconceptions are widely shared, and many, no doubt, are warranted even though you might not be in a position to vouch for them were you called upon to do so.

      Socrates observed that an unexamined life was not worth living. He did not mean that a life worth living requires having all the answers. He meant that we should recognize what we know and what we only think we know: we should understand our limitations and what these might portend. This is the spirit in which I offer this book. The goal is not to parade a string of metaphysical doctrines past you and declaim their pros and cons. The goal, rather, is to encourage you to reflect on matters that, for most of us, most of the time, remain beneath reflection.

      This book approaches metaphysics, not as an academic subject to be mastered then forgotten, but as a hands-on exercise, the lasting value of which lies in the doing. For this reason, I have not tried to hide my own views, an impossibility in any event. That might be worrisome were it not the case that the views are the vehicles, not the destinations. If I succeed in persuading you that metaphysics, far from being a purely academic pastime, is unavoidable, I will be content. If I leave you better equipped to recognize hidden metaphysical themes for what they are, I will be delighted.

      Although the book presupposes no prior acquaintance with metaphysics, I have tried to steer the conversation in ways that might engage even hardened academic philosophers. If you are among their ranks, you are hereby forewarned not to expect exhaustive treatments of individual metaphysical doctrines. There is a time and a place for everything, and this is neither the time, nor the place, for exhaustive treatments of anything.

      July 2020

      What is Metaphysics? took shape in Melbourne during my tenure as a Fulbright Fellow in the first half of 2020. I am much indebted to the Australian–American Fulbright Commission and to Monash University, my host institution, for their support. The Fellowship, which was meant to run from mid-February through June, was cut short by the onset of the Covid-19 pandemic, but I remained in Australia with my wife, Harrison, and continued working from our adopted home in Caulfield South thanks to the graciousness of Marie-Thérèse Jensen. My stay at Monash would not have been possible without the support of Christina Twomey, Head of the School of Philosophical, Historical, and International Studies; Jakob Hohwy, Head, Department of Philosophy; and Jessica Weijers, School Manager, who deserves a gold parking pass.

      Keith Campbell and John Bigelow, both important figures in Australian philosophy, have continued to exert a powerful gravitational pull on my thoughts, although not always in the same direction. I have also been influenced at close range by Jonathan Bennett, Alex Carruth, Randolph Clarke, Heather Dyke, Anthony Fisher, Frank Jackson, Jaegwon Kim, Anna Marmodoro, Yitzhak Melamed, Elizabeth Miller, Gonzalo Rodriguez-Pereyra, Peter Simons, Roy Sorensen, Galen Strawson, and Peter van Inwagen. I am most grateful to four anonymous readers who provided insightful advice and managed to convince me to temper my worst instincts, and to Ian Tuttle for finding and correcting numerous gaffes and infelicities. Harrison Hagan Heil suffered through successive versions of the book, offered invaluable counsel, and, more than anyone else, helped shape its character.

      Pascal Porcheron, my editor at Polity Press, encouraged me to persevere in the project that resulted in this book. An old adage has it that the best way to learn something is to teach it. To the extent that this is true, it is true because you do not fully understand something until you can explain it to yourself, a prerequisite for teaching it to others. Writing this book afforded me the rare opportunity to do both, and for that I am especially grateful to Pascal and to Polity Press.

       1.0 Metaphysics Is . . . What?

      This book is addressed to readers curious about metaphysics. Today, purveyors of serious metaphysics reside in university philosophy departments, or, at any rate, would have spent time in academic settings. The book’s aim, however, is to convince you that, far from being an effete academic pastime, metaphysics is inevitable. Each of us embraces metaphysical theses, often without recognizing them as such. Philosophers are not the only philosophers. What distinguishes card-carrying, capital-P Philosophers from everyone else is just that the Philosophers embrace metaphysical doctrines self-consciously.

      So conceived, metaphysics has a long history, and a much longer prehistory. This is not a historical survey, however, but a foray into a subject matter that runs the historical gamut. One underlying theme is that, whether anyone likes it or not, metaphysics is pervasive. Self-proclaimed skeptics who dismiss metaphysics as a frivolous waste of time most often do so on the basis of unexamined metaphysical commitments of their own, commitments unlikely to survive honest scrutiny.

      I will try to convince you of metaphysics’ inevitability, not by argument, but, starting with this chapter, by example. Because the book is meant to draw in nonspecialists, its focus will be on broad theses and suggestive arguments, rather than on the fine-grained details of these theses and arguments. This is not a matter of dumbing down the subject. The Devil is in the details, but the chief interest in, and significance of, metaphysics lies less in the details than in the extent to which metaphysics provides satisfying proposals for solutions to issues that lie just below the surface of everyday life, the arts, and the sciences.

      I could tell you that metaphysics is the study of being or the nature of reality, but that does not set metaphysics off from hosts of other subjects including, but not limited to, the sciences. I could tell you that metaphysics provides our most general characterization of what there is, leaving more specific characterizations to the various sciences. But again, this does little to distinguish metaphysics from physics, the most general of the sciences.

      Some suppose that metaphysics is
