“quite the contrary, if he can only get at him, he will run him through with his bayonet. That is the nature of all religious teaching in this country. I do not think that that is a very good way of carrying out the precepts of religion. I think if it is a good thing for a boy to love his enemy, it is good for a grown-up man." "There are in Europe twenty-eight millions of men under arms," says Wilson, "to decide disputes, not by discussion, but by murdering one another. That is the accepted method for deciding disputes among Christian nations.” source
