" science,” for the Aristotelian, is an organized body of demonstrated truths concerning the things falling within some domain and their causes. Hence, not only physics, chemistry, biology, and the like, but also metaphysics, ethics, natural theology, and indeed the philosophy of nature itself (since, for the Aristotelian-Thomistic thinker, these fields of inquiry rest on rational arguments and analysis no less than physics, chemistry, etc. do) count as sciences.
