The attempts to prevent war and unify the nations can meet with no success while we make no attempt to discipline the violent impulses and greedy calculations which cause war. Only when human evolution has gone farther, and the brute's instincts have been sufficiently disciplined in us, shall we drop war. But the clash of egoisms will still remain. Our frictions and battles will continue; their outer form will, however, change for the better and be lifted to a plane more truly human and beyond the merely animal.
