placed before us is of another sort. The virtues of daring and endurance
will never fail in any vitally progressive community of men, alike in
the causes of war and of peace.[10] But on the one hand we find those
virtues at work in the service of humanity, creating ever new marvels of
science and of art, adding to the store of the precious heirlooms of the
race which are a joy to all mankind. On the other hand, we see these
same virtues in the service of savagery, extinguishing those marvels,
killing their creators, and destroying every precious treasure of
mankind within reach. That--it seems to be one of the chief lessons of
this war--is the choice placed before us who are to-day called upon to
build the world of the future on a firmer foundation than our own world
has been set.

a very late and highly developed stage of Magdalenian culture, there
are indications that human brains were eaten (Zaborowski, _L'Homme
Prehistorique_, p. 86). It is surmised that they were the brains of
enemies killed in battle, but this remains a surmise.
