“Nations are represented not merely as self-centered, independent moral systems, but as, in some degree, mutually repellent systems. This notion is partly the product of the false patriotic teaching of our schools and press, which seek to feed our sense of national unity more upon exclusive than inclusive sentiments. Nations are represented as rivals and competitors in some struggle for power, or greatness, or prestige, instead of as coöperators in the general advance of civilization.”
