Even Dr.Wayland considers it not only the right, but the duty of individuals and of society to resort to these means, and to enact these laws for self-protection.

Let us extend the same course of reasoning to the relations of different societies.
We live among nations who frequently wage unjust wars; who, disregarding the rights of others, oppress and rob, and even murder their citizens, in order to reach some unrighteous end.

As individuals, we build fences and walls for the protection of our grounds and our merchandise; so, as a nation, we build ships and forts to protect our commerce, our harbors, and our cities.

But the walls of our houses and stores are useless, unless made so strong and high that the robber cannot break through or scale them without great effort and personal danger; so our national ships and forts would be utterly useless for protection, unless fully armed and equipped.
Further: as individuals and as societies we employ civil officers for the protection of our property and lives, and, when necessary, arm them with the physical means of executing the laws, even though the employment of these means should cost human life.

The prevention and punishment of crime causes much human suffering; nevertheless the good of community requires that crime should be prevented and punished.
