succeeded well. It does not show why some races have
the wit to change to a better environment or transform the old
environment.

There seems to be a great persistency of individual traits, of family
traits, and, in a still larger generalization, of racial traits which
culture fails to obliterate. As these differences of traits seem to be
universal, it appears that the particular combination which gives motor
power may also be a differentiation. At least, as all races have had
the same earth, why, if they are so equal in the beginning, would they
not achieve? Had they no inventive power? Also, when these so-called
retarded races came in contact with the more advanced races who were
superior in arts and industries, why did they not borrow, adapt, and
utilize these productions? There must have been something vitally
lacking which neither the qualities of the individual nor the stimulus
of his surroundings could overcome. Some have deteriorated, others
have perished; some have reached a stationary existence, while others
have advanced. Through hereditary changes, nature played the {26} game
in her own way with the leading cards in her own hand, and some races
lost. Hence so with races, so with individuals.

_Progress Is Enhanced by the Interaction of Groups and Races_.--The
accumulation of civilization and the state of progress may be much
determined by the interaction of races and groups. Just as individual
personality is developed by contact with others, so the actions and
reactions of tribes and races in contact bring into play the utility of
discoveries and inventions. Thus, knowledge of any kind may by
diffusion become a heritage of all races. If one tribe should acquire
the art of making implements by chipping flint in a certain way, other
tribes with which it comes in contact might borrow the idea and extend
it, and thus it becomes spread over a wide area. However, if the
original discoverer used the chipped flint for skinning animals, the
one who would borrow the idea might use it to make implements of
warfare.

Thus, through borrowing, progress may be a co-operative process. The
reference to people in any community reveals the fact that there are
few that lead and many that follow; that there is but one Edison, but
there are millions that follow Edison. Even in the educational world
there are few inventors and many followers. This is evidence of the
large power of imitation and adaptation and o
