I see this as the central issue of our time: how to find a substitute for war in human ingenuity, imagination, courage, sacrifice, patience... War is not inevitable, however persistent it is, however long a history it has in human affairs. It does not come out of some instinctive human need. It is manufactured by political leaders, who then must make a tremendous effort--by enticement, by propaganda, by coercion--to mobilize a normally reluctant population to go to war.
If you remove adversity, you remove ingenuity and creativity with it. There is no need to strive to make something beautiful or better if it already is.
