and the fiercest races of fighters would be just the ones to survive and
perpetuate their kind. Those most successful primitive men, from whom
civilized peoples are descended, must have excelled in treachery and
cruelty, as in quickness of wit and strength of will. That moral sense
which makes it seem wicked to steal and murder was scarcely more
developed in them than in tigers or wolves. But to all this there was
one exception. The family supplied motives for peaceful coöperation.[12]
Within the family limits fidelity and forbearance had their uses, for
events could not have been long in showing that the most coherent
families would prevail over their less coherent rivals. Observation of
the most savage races agrees with the comparative study of the
institutions of civilized peoples, in proving that the only bond of
political union recognized among primitive men, or conceivable by them,
was the physical fact of blood-relationship. Illustrations of this are
found in plenty far within the historic period. The very township, which
under one name or another has formed the unit of political society among
all civilized peoples, was originally the stockaded dwelling-place of a
clan which traced its blood to a common ancestor. In such a condition of
things the nearest approach ever made to peace was a state of armed
truce; and while the simple rules of morality were recognized, they were
only regarded as binding within the limits of the clan. There was no
recognition of the wickedness of robbery and murder in general.

This state of things, as above hinted, could not come to an end as long
as men obtained food by seizing upon edible objects already in
existence. The supply of fish, game, or fruit being strictly limited,
men must ordinarily fight under penalty of starvation. If we could put a
moral interpretation upon events which antedated morality as we
understand it, we should say it was their duty to fight; and the
reverence accorded to the chieftain who murdered most successfully in
