Civilization being agreement, barbarism has no chance in the long run (41. 67):
41. 76. For barbarism implies not only a quarrel between any barbarist and any civilized man; it also implies a quarrel between anyone barbarist and any other; and that any state of harmony between them is merely this quarrel suspended.
The barbarist is somebody “who imitates the conditions of an uncivilized world” (41. 53); but an actual attempt to bring about those conditions will need cooperation, and this will be a step towards civility. Here perhaps we should distinguish cooperation from the kind of coerced organization seen in a fascist state. Specific examples will be considered in the later chapters of Part IV of the New Leviathan. We are now considering “What Barbarism Is,” in general terms.
