Natural philosophy or philosophy of nature (from Latin philosophia naturalis) was the philosophical study of nature and the physical universe that was dominant before the development of modern science. It is considered to be the precursor of natural science. / Natural philosophy, as distinguished from metaphysics and mathematics, is traditionally understood to encompass a wide range of subjects which Aristotle included in the physical sciences.
