The government of a people by itself has a meaning and a reality, but such a thing as government of one people by another does not and can not exist.

Context

“Responsibility to an authority which has gone through none of the labor, acquired none of the capacity, and for the most part is not even aware that either, in any peculiar degree, is required, can not be regarded as a very effectual expedient for accomplishing these ends. The government of a people by itself has a meaning and a reality, but such a thing as government of one people by another does not and can not exist. One people may keep another as a warren or preserve for its own use, a place to make money in, a human-cattle farm to be worked for the profit of its own inhabitants; but if the good of the governed is the proper business of a government, it is utterly impossible that a people should directly attend to it.” source
