From what has been said it is evident that competition and coöperation
are twin principles in the evolution of social groups. While competition
characterizes in the main the relation between groups, especially
independent political groups, and while coöperation characterizes in the
main the relation of the members of a given group to one another, still
competition and coöperation are correlatives in practically every phase
of the social life. Some degree of competition, for example, has to be
maintained by every group between its members if it is going to maintain
high standards of efficiency or of loyalty. If there were no competition
with respect to the matters that concern the inner life of groups, it is
evident that the groups would soon lose efficiency in leadership and in
membership and would sooner or later be eliminated. Consequently
society, from certain points of view, presents itself to the student at
the present time as a vast competition, while from other standpoints it
presents itself as a vast coöperation.

It follows from this that competition and coöperation are both equally
important in the life of society. It has been a favorite idea that
competition among human beings should be done away with, and that
coöperation should be substituted to take its place entirely. It is
evident, however, that this idea is impossible of realization. If a
social group were to check all competition between its members, it would
stop thereby the process of natural selection or of the elimination of
the unfit, and, as a consequence, would soon cease to progress. If some
scheme of artificial selection were substituted to take the place of
natural selection, it is evident that competition would still have to be
retained to determine who were the fittest. A society that would give
positions of trust and responsibility to individuals without imposing
some competitive test upon them would be like a ship built partially of
good and partially of rotten wood,--it would soon go to pieces.
