"Metaphysics or Ontology? masterfully treats not only the history of the controversy, but also many important metaphysical questions that have been raised over the centuries. What is at stake are the most fundamental and important questions philosophers can ask such as (1) How should we understand being—as real or possible?, (2) How should we understand existence—as actuality or as a mode of essence?, and (3) What has priority, essence or existence? This is a book that will reward the reader with new insights each time it is read; it deserves the special attention of scholars and philosophers for decades to come."Robert Anthony Delfino, St. John’s University, New York
