Now I do not wish to imply that I think it was possible to resettle Europe consistently on any one of these principles. I am certain that it was not. The very use of these principles, so pretentious and so absolute, meant that the spirit of accommodation did not prevail and that, therefore, the substance of peace was not there. For the moment you start to discuss factories, mines, mountains, or even political authority, as perfect examples of some eternal principle or other, you are not arguing, you are fighting.
That eternal principle censors out all the objections, isolates the issue from its background and its context, and sets going in you some strong emotion, appropriate enough to the principle, highly inappropriate to the docks, warehouses, and real estate. And having started in that mood you cannot stop.
