Hilaire Belloc, This and That and the Other

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.

The Barbarian wonders what strange meaning may lurk In that ancient and solemn truth, " Sine Auctoritate nulla vita."

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.

We permit our jaded intellects to play with drugs of novelty for the fresh sensation they arouse, though we know well there is no good in them, but only wasting at the last. Yet there is one real interest in watching the Barbarian and one that is profitable. The real interest of watching the Barbarian is not the amusement derivable from his antics, but the prime doubt whether he will succeed or no, whether he will flourish. He is, I repeat, not an agent, but merely a symptom, yet he should be watched as a symptom. It is not he in his impotence that can discover the power to disintegrate the great and ancient body of Christendom, but if we come to see him triumphant we may be certain that that body, from causes much vaster than such as he could control, is furnishing him with sustenance and forming for him a congenial soil—and that is as much as to say that we are dying.
