Metaphysics: The Fundamentals presents readers with a systematic, comprehensive introductory overview of modern analytic metaphysics. This accessible, up-to-date, and broad-ranging survey of one of the most dynamic and often daunting sub-fields in contemporary philosophy introduces key thinkers such as Descartes, Leibniz, Russell, David Lewis, Alvin Plantinga, Kit Fine, Peter van Inwagen, John Hawthorne, and many others. The book explores fundamental questions while identifying important assumptions, axioms, and methodological principles. It addresses topics in ontology, modality, causality, universals, material composition, persistence, space, and time.
