The three centuries which follow the downfall of the empire of
Charlemagne laid the foundations of modern Europe, and made of it a
world wholly different, politically, socially, and religiously, from
that which had preceded it. In the careers of Greece and Rome we saw
exemplified the results of two sharply opposing tendencies of the Aryan
mind, the one toward individualism and separation, the other toward
self-subordination and union.

In the time of Charlemagne's splendid successes it appeared settled that
the second of these tendencies was to guide the Teutonic Aryans, that
the Europe of the future was to be a single empire, ever pushing out its
borders as Rome had done, ever subduing its weaker neighbors, until the
"Teutonic peace" should be substituted for the shattered "Roman peace,"
soldiers should be needed only for the duties of police, and a whole
civilized world again obey the rule of a single man.

Instead of this, the race has since followed a destiny of separation.
Europe is divided into many countries, each of them a vast camp
bristling with armies and arsenals. Civilization has continued
hag-ridden by war even to our own day, and, during at least seven
hundred of the years that followed Charlemagne, mankind made no greater
progress in the arts and sciences than the ancients had sometimes
achieved in a single century. We do indeed believe that at last we have
entered on an age of rapid advance, that individualism has justified
itself. The wider personal liberty of to-day is worth all that the race
has suffered for it. Yet the retardation of wellnigh a thousand years
has surely been a giant price to pay.
