68:1.4

Primitive human beings early learned that groups are vastly greater and stronger than the mere sum of their individual units. One hundred men united and working in unison can move a great stone; a score of well-trained guardians of the peace can restrain an angry mob. And so society was born, not of mere association of numbers, but rather as a result of the organization of intelligent co-operators. But co-operation is not a natural trait of man; he learns to co-operate first through fear and then later because he discovers it is most beneficial in meeting the difficulties of time and guarding against the supposed perils of eternity.
