Politically speaking, tribal nationalism [patriotism] always insists that its own people are surrounded by 'a world of enemies' - 'one against all' - and that a fundamental difference exists between this people and all others.

That Hegelian dialectics should provide a wonderful instrument for always being right, because they permit the interpretations of all defeats as the beginning of victory, is obvious.
