You will do away with the military frontiers, and those economic and commercial barriers which are still worse. Protection introduces violence into the expansion of labor; like militarism, it brings in a fatal absence of balance. You will suppress that which justifies among nations the things which among individuals we call murder, robbery, and unfair competition. You will suppress battles — not nearly so much by the direct measure of supervision and order that you will take as because you will suppress the causes of battle. You will suppress them chiefly because it is you who will do it, by yourself, everywhere, with your invincible strength and the lucid conscience that is free from selfish motives. You will not make war on yourself.
