Chapter 18

“According to the doctrine now stated, the highest, or rather the only proper object of physics, is to ascertain those established conjunctions of successive events, which constitute the order of the universe; to record the phenomena which it exhibits to our observations, or which it discloses to our experiments; and to refer these phenomena to their general laws.”—D. STEWART, _Elements of the Philosophy of the Human Mind_, vol. ii. chap. iv. sect. 1.
