This book treats values as the basis for all of philosophy, an approach distinct from critiquing theories of value and far rarer. “First Philosophy,” the effort to justify the foundations for a system of philosophy, is one of the main issues that divide philosophers today. McDonald’s philosophy of values is a comprehensive attempt to replace philosophies of “existence,” “being,” “experience,” the “subject,” or “language,” with a philosophy that locates value as most basic. This transformation is a radical move within Western philosophy as a whole, since it has never been done in such a thoroughgoing way. Hugh P. McDonald makes a comprehensive case against first philosophy as metaphysical, by mounting a case against all metaphysical systems of philosophy. Radical Axiology: A First Philosophy of Values is a fresh start for a rebirth of philosophy. While other movements debate the “death of philosophy,” this book radically re-evaluates the direction of philosophy by discovering values at the basis of all philosophy. This reorientation addresses the question of what the love of wisdom can mean for us today.
