Civilization is a movement and not a condition, a voyage and not a harbor. - Arnold J. Toynbee

On a stationary military frontier between a civilization and a barbarism, time always works in the barbarians' favour; and, besides this, the barbarians' advantages increases in geometrical progression at each arithmetical addition to the length of the line which the defenders of the civilization have to hold

If we are frank with ourselves, we shall admit that we are engaged on a deliberate and sustained and concentrated effort to impose limitations upon the sovereignty and independence of the fifty or sixty local sovereign independent States which at present partition the habitable surface of the earth and divide the political allegiance of mankind.
It is just because we are really attacking the principle of local sovereignty that we keep on protesting our loyalty to it so loudly. The harder we press our attack upon the idol, the more pains we take to keep its priests and devotees in a fool’s paradise—lapped in a false sense of security which will inhibit them from taking up arms in their idol’s defense. The local national state, invested with the attributes of sovereignty — is an abomination of desolation standing in the place where it ought not. It has stood in that place now — demanding and receiving human sacrifices from its poor deluded votaries — for four or five centuries. Our political task in our generation is to cast the abomination out, to cleanse the temple and to restore the worship of the divinity to whom the temple rightfully belongs. In plain terms, we have to re-transfer the prestige and the prerogatives of sovereignty from the fifty or sixty fragments of contemporary society to the whole of contemporary society — from the local national states by which sovereignty has been usurped, with disastrous consequences, for half a millennium, to some institution embodying our society as a whole.
In the world as it is today, this institution can hardly be a universal Church. It is more likely to be something like a League of Nations. I will not prophesy. I will merely repeat that we are at present working, discreetly but with all our might, to wrest this mysterious political force called sovereignty out of the clutches of the local national states of our world. And all the time we are denying with our lips what we are doing with our hands...

Of the twenty or so civilizations known to modern Western historians, all except our own appear to be dead or moribund, and, when we diagnose each case, in extremis or post mortem, we invariably find that the cause of death has been either War or Class or some combination of the two. To date, these two plagues have been deadly enough, in partnership, to kill off nineteen out of twenty representatives of this recently evolved species of human society; but, up to now, the deadliness of these scourges has had a saving limit.
