Nyskick. Nature into departments for the convenience of study, has been one of the chief conditions of scientific progress. It is true that such separation is made for our convenience and does not exist in Nature. Yet it has been the means of revealing the unity of Nature, the connection of facts, the harmony of laws: analysis has been the necessary preliminary to an intelligent synthesis. No further apology need be offered for the separation of Logic in the present volume, from all other studies, and especially from Psychology and Metaphysics, with greater vigour than has been usual in logical treatises :carrying out the plan that elsewhere has always proved advantageous. The instructed reader will easily see that I have been chiefly indebted to Mills System of Logic, Professor Bain's Logic, Dr. Venn's Empirical Logic, and Dr. Keyne's Formal Logic. Whatever is due to other authors has been acknowledged as occasion arose. In every case I have tried to make the property conveyed my own: an excuse for theft that must seem odd to a lawyer, but is well recognised in the courts of literature.
