Book excerpt: Idealism is a family of metaphysical views each of which gives priority to the mental. The best-known forms of idealism in Western philosophy are Berkeleyan idealism, which gives ontological priority to the mental (minds and ideas) over the physical (bodies), and Kantian idealism, which gives a kind of explanatory priority to the mental (the structure of the understanding) over the physical (the structure of the empirical world). Although idealism was once a dominant view in Western philosophy, it has suffered almost total neglect over the last several decades. This book rectifies this situation by bringing together seventeen essays by leading philosophers on the topic of metaphysical idealism. The various essays explain, attack, or defend a variety of idealistic theories, including not only Berkeleyan and Kantian idealisms but also those developed in traditions less familiar to analytic philosophers, including Buddhism and Hassidic Judaism. Although a number of the articles draw on historical sources, all will be of interest to philosophers working in contemporary metaphysics. This volume aims to spark a revival of serious philosophical interest in metaphysical idealism.
