From Observables to Unobservables in Science and Philosophy focuses on knowing unobservable real things or attributes by means of observing real things or attributes, a topic central to twentieth-century scientific philosophy. Engaging both current and perennial issues in metaphysics, epistemology, philosophy of nature and of science, Connell writes from a realist perspective. He adds a cogent, well written, and much needed voice to the current debate over foundationalism from the perspective of the undersubscribed quarter of empirical realism. Principal audiences for this volume will be scholars and graduate students in philosophy, working in the Aristotelian tradition.
