CHAP. CHAP. VII. Of the Logic of MATHEMATICS. VERY thing that is the subject of human knowledge belongs either to Mind or Body. The two parts of learning, METAPHYSIC and LOGIC, which have been touched in a fummary way in the preceeding pages, treat more immediately of MIND, its powers and operations, its acts and energies. The former, producing by fpeculation the general Principles of all other parts of knowledge, or at leaft affecting to produce them, is the univerfal Science; and the latter, descending more practically to the particular invefti times before: for it is only by trying many and different roads to Knowledge that men can find out the right one to her temple.

All the other Sciences and Arts, as has been before obferved, apply to particular Subjects, which are of different kinds and various extent. PHYSICS is the Science which treats more immediately of BODY, or matter organized, its properties and affections, its motions and operations, its qualities, and internal struc ture. Between these Sciences of Mind and Body lies one, which is intermediate and which partakes of both, taking its subject from the * See Ariftot. Metaph. lib. iv. cap. 2.
