" A world made one, by the political union of its parts, would not only require of its citizen a shift of allegiance, but it would deprive him of the enormous personal satisfaction of distrusting what he doesn't know and despising what he has never seen. This would be a severe deprivation, perhaps an intolerable one. The awful truth is, a world government would lack an enemy, and that is a deficiency not to be lightly dismissed. It will take a yet undiscovered vitamin to supply the blood of man with a substitute for national ambition and racial antipathy; but we are discovering new vitamins all the time, and I am aware of that too. "
