Scientific Metaphysics collects original essays by leading philosophers of science on the question of whether metaphysics can and should be naturalized--that is, conducted as a part of natural science. Some people think the idea of naturalized metaphysics is a contradiction in terms: metaphysics is by definition about matters that transcend the domain of empirical inquiry. Most of the authors here disagree: they argue that if metaphysics is to hold outany prospect of identifying objective truths, it must be continuous with and inspired by science, or even be of some positive use to science. The essays offer various points of view on the relationship between naturalized metaphysics, more traditional forms of metaphysics, and the wider history of philosophy, and draw on examples from physics, biology, economics, psychology. At stake is the question of whether metaphysics should give way to science and disappear from contemporary inquiry, orcontinue as aactivity that unifies the particular sciences into a single naturalistic worldview.
