[I]n the very first place, Democracy, like Monarchy, like Aristocracy, like any other government, must preserve the national existence. The first necessity of a State is that it should be durable. Among mankind regarded as assemblages of individuals, the gods are said to love those who die young; but nobody has ventured to make such an assertion of States. The prayers of nations to Heaven have been, from the earliest ages, for long national life, life from generation to generation, life prolonged far beyond that of children's children, life like that of the everlasting hills.
...Next perhaps to the paramount duty of maintaining national existence, comes the obligation incumbent on Democracies, as on all governments, of securing the national greatness and dignity. Loss of territory, loss of authority, loss of general respect, loss of self-respect, may be unavoidable evils, but they are terrible evils.
