In 1851, Herbert Spencer Wrote:

Morality knows nothing of geographical boundaries, or distinctions of race. You may put men on opposite sides of a river or a chain of mountains; may else part them by a tract of salt water; may give them, if you like, distinct languages; and may even colour their skins differently; but you cannot change their fundamental relationships. Originating as these do in the facts of man’s constitution, they are unalterable by the accidents of external condition. The moral law is cosmopolite – is no respecter of nationalities: and between men who are the antipodes of each other, either in locality or anything else, there must still exist the same balance of rights as though they were next-door neighbours in all things.
