We may be assured by past experience, that such a practice [as some states charging high taxes on goods from other states] would be introduced by future contrivances; and both by that and a common knowledge of human affairs, that it would nourish unceasing animosities, and not improbably terminate in serious interruptions of the public tranquility.

As compacts, charters of government are superior in obligation to all others, because they give effect to all others. As truths, none can be more sacred, because they are bound, on the conscience by the religious sanctions of an oath. As metes and bounds of government, they transcend all other land-marks, because every public usurpation is an encroachment on the private right, not of one, but of all.
