If we didn't possess certain beliefs about such things as time, appearance and reality, and how effect follows cause, we wouldn't be able to get out of bed in the morning, let alone read a book about metaphysics, which is the study of our experience and those ideas, or presuppositions, which allow us to make sense of it. Drawing on examples from art, science, and daily life, John Heil shows how metaphysics begins in questioning our everyday assumptions about how the world "works" and ends with speculation on the nature of the universe itself. In chapters that cover the major topics in the academic study of metaphysics, from free will and consciousness to time and objectivity, Heil explains how metaphysical questions underpin everything human beings do. This accessible book will show you how professional philosophers try to categorize and make sense of our world of perception and experience and explains why everyone should take metaphysics seriously.
