The great right of migration and the great wisdom of incorporating foreign elements into our body politic, are founded not upon any genealogical or ethnological theory, however learned, but upon the broad fact of a common nature. Man is man the world over. This fact is affirmed and admitted in any effort to deny it. The sentiments we exhibit, whether love or hate, confidence or fear, respect or contempt, will always imply a like humanity. A smile or a tear has no nationality. Joy and sorrow speak alike in all nations, and they above all the confusion of tongues proclaim the brotherhood of man.
