To gain the cohesion of large numbers of men by whom wealth could be
created and sufficient leisure and independence secured for an
intellectual life, not dictated by the necessities of existence, a
special concurrence of favourable physical conditions was required. The
rich and secluded river-basins of many parts of the world provided this,
and in consequence we find similar large communities arising at the end
of the Stone Age in such places as China, Peru, Mexico, and above all in
Mesopotamia and Egypt. The last named derived their special importance
for the sequel from their proximity to the Mediterranean, which was to
act as the great meeting-place and training-school for adventurous
spirits and inquiring minds. From the busy intercourse of these
land-locked waters arose the civilization called Minoan, or Aegean,
centring in Crete, itself to be surpassed by the trading activity of the
Phoenicians and the art and science of the Greeks.

It is with the advent of the Greek that the seal is placed upon the
claim of the Mediterranean to be the birthplace of the highest type of
human civilization, the centre from which a unity of the spirit was to
spread, until, by material force as well as by the conquering mind, the
European or Western man was recognized as in the forefront of the race.
The supremacy of the Greek lay in his achievement in three directions,
as a thinker, as an artist, and as the builder of the city-state. For
our present purpose the first and the last are the most important and
the first the most important of all.

The city-state was important as the first example of a free,
self-governing community in which the individual realized his powers by
living--and dying--with and for his fellows. This new type of human
community was of the highest moment in the sequel. In many points it was
a model to the Romans, and thus became a fulcrum for the upward movement
