There never did, there never will, and there never can exist...

There never did, there never will, and there never can exist a parliament, or any description of men, or any generation of men, in any country, possessed of the right or the power of binding and controlling posterity to the 'end of time,' or of commanding for ever how the world shall be governed, or who shall govern it. ... Every age and generation must be as free to act for itself, in all cases, as the ages and generations which preceded it.
