Makes sense that the document should change as the world changes.
“Some men look at constitutions with sanctimonious reverence, and deem them like the ark of the covenant, too sacred to be touched. They ascribe to the men of the preceding age a wisdom more than human, and suppose what they did to be beyond amendment… Each generation is as independent of the one preceding, as that was of all which had gone before. It has then, like them, a right to choose for itself the form of government it believes most promotive of its own happiness… It is now forty years since the constitution of Virginia was formed. The same tables inform us, that, within that period, two-thirds of the adults then living are now dead. Have then the remaining third, even if they had the wish, the right to hold in obedience to their will, and to laws heretofore made by them, the other two-thirds, who, with themselves, compose the present mass of adults? … That majority, then, has a right to depute representatives to a convention, and to make the constitution what they think will be the best for themselves.” ~ Thomas Jefferson
