A doctrine of war is made up of the principles of war which, having passed through the critical and constructive mind of man, or a number of men, have become a general body of instruction, by the light of which are solved the concrete problems of war.—Unsigned article in Edinburgh Review.
History teaches that war is inevitable. It is the teaching of the Bible, both of the old and new dispensations. From Genesis to Revelations, war is the all-inspiring theme of prophets, priests, and kings. Even He who was no disturber of the people said: "Where a strong man armed keepeth his palace, his goods are in peace; but when a stronger than he come upon him and overcome him, he taketh from him his armor wherein he trusted, and divideth the spoils." It is axiomatic that a nation that will not fight becomes a prey to those that will. "Without the fighting instinct," says one, "men become soft and effeminate." This was the condition of Prussia after Frederick the Great until Waterloo. It was Bismarck who declared that a nation could only be held together by blood and iron and not by declamations and resolutions.
