"[This] book is well written in a no-nonsense style. First Rate." (The Philosophical Quarterly)"An exceptionally good introduction and tour through central topics in contemporary metaphysics. The book could easily be used alone for an upper level course in metaphysics or as a commentary alongside original articles. It is written clearly, with illuminating examples and engaging discussion." (Review of Metaphysics)"Macdonald's Varieties of Things: Foundations of Contemporary Metaphysics is an excellent study in ontology. It provides a descriptive metaphysical account of the ontology of material substances, persons, events, and universals. While the book provides a sophisticated account of the issues, it is written in a way that makes it accessible to an advanced undergraduate student audience. And given its novel defenses of some positions, it will also be of considerable interest to professional philosophers working on the issues" —Brian McLaughlin, Rutgers University"Amongst the book’s most notable virtues are its clarity and the author’s careful attention to detail in setting out arguments and counter-arguments for various positions. The opening chapters on the nature of metaphysics are excellent. The later chapters on material substances, persons, events, and universals are thorough, closely argued and well informed."—Jonathan Lowe, University of Durham
