Unquestionably the States have the powers and rights reserved to them in and by the National Constitution; but among these surely are not included all conceivable powers, however mischievous or destructive, but at most such only as were known in the world at the time as governmental powers; and certainly a power to destroy the Government itself had never been known as a governmental — as a merely administrative power. This relative matter of national power and State rights, as a principle, is no other than the principle of generality and locality . Whatever concerns the whole should be confided to the whole — to the General Government — while whatever concerns only the State should be left exclusively to the State. This is all there is of original principle about it. Whether the National Constitution in defining boundaries between the two has applied the principle with exact accuracy is not to be questioned. We are all bound by that defining without question.
