Barbarians always think of themselves as the bringers of civilization.

Has it struck you that the music which is regarded as the most sublime in western civilization, which is the music of Bach, is called baroque?

By the middle twentieth century, few European nation-states had not at one time or another figured themselves as 'the outpost of Western Christian civilisation': France, imperial Germany, the Habsburg Reich, Poland with its self-image as przedmurze (bastion), even tsarist Russia. Each of these nation-state myths identified "barbarism" as the condition or ethic of their immediate eastward neighbour: for the French, the Germans were barbarous, for the Germans it was the Slavs, for the Poles the Russians, for the Russians the Mongol and Turkic peoples of Central Asia and eventually the Chinese.

There is always a city. There is always a civilization. There is always a barbarian with a pickaxe. Sometimes you are the city, sometimes you are the civilization, but to become that city, that civilization, you once took a pickaxe and destroyed what you hated, and what you hated is what you did not understand.

Take a sound from whatever source, a note on a violin, a scream, a moan, a creaking door, and there is always this symmetry between the sound basis, which is complex and has numerous characteristics which emerge through a process of comparison within our perception.

The Barbarian hopes — and that is the mark of him, that he can have his cake and eat it too.He will consume what civilization has slowly produced after generations of selection and effort, but he will not be at pains to replace such goods, nor indeed has he a comprehension of the virtue that has brought them into being. Discipline seems to him irrational, on which account he is ever marvelling that civilization, should have offended him with priests and soldiers.... In a word, the Barbarian is discoverable everywhere in this, that he cannot make: that he can befog and destroy but that he cannot sustain; and of every Barbarian in the decline or peril of every civilization exactly that has been true.

We sit by and watch the barbarian. We tolerate him in the long stretches of peace, we are not afraid. We are tickled by his irreverence; his comic inversion of our old certitudes and our fixed creed refreshes us; we laugh. But as we laugh we are watched by large and awful faces from beyond, and on these faces there are no smiles.
