of one are made known for the benefit of another, the inventions of one are added to the inventions of another; without intercommunication of ideas the intellect must lie dormant. Thus it is with individuals, and with societies it is the same. Acquisitions are eminently reciprocal. In society, wealth, art, literature, polity, and religion act and react on each other; in science a fusion of antagonistic hypotheses is sure to result in important developments. Before much progress can be made, there must be established a commerce between nations for the interchange of aggregated human experiences, so that the arts and industries acquired by each may become the property of all the rest, and thus knowledge becomes scattered by exchange, in place of each having to work out every problem for himself. Thus viewed, civilization is a partnership entered into for mutual improvement; a joint stock operation, in which the product of every brain contributes to a general fund for the benefit of all. No one can add to his own store of knowledge without adding to the general store; every invention, and discovery, however insignificant, is a contribution to civilization.
In savagism, union and coöperation are imperfectly displayed. The warriors of one tribe unite against the warriors of another; a band will coöperate in pursuing a herd of buffalo; even one nation will sometimes unite with another nation against a third, but such combinations are temporary, and no sooner is the particular object accomplished than the confederation disbands, and every man is again his own master. The moment two or more persons unite for the accomplishment of some purpose which shall tend permanently to meliorate the condition of themselves and others, that moment progress begins. The wild beasts of the forest, acting in unison, were physically able to rise up and extirpate primitive man, but could beasts in reality confederate and do this, such confederation of wild beasts could become civilized.
