On June 12, 1816, Thomas Jefferson wrote a long letter to Samuel Kercheval in response to a letter from Kercheval.
In the letter, Jefferson starts out saying the original Constitution does not form a truly republican form of government because there are too many situations in which the people are not equally represented. He said the House of Representatives is only elected by half the people, the Senate is not proportionate to population, the President is elected by electors or the House Of Representatives, the President’s cabinet is elected by no one, and the judges of the Supreme Court are not elected by the people.
“Where then is our republicanism to be found? Not in our constitution certainly, but merely in the spirit of our people. That would oblige even a despot to govern us republicanly. Owing to this spirit, and to nothing in the form of our constitution, all things have gone well. But this fact, so triumphantly misquoted by the enemies of reformation, is not the fruit of our constitution, but has prevailed in spite of it. Our functionaries have done well, because generally honest men. If any were not so, they feared to show it.”
“The sum of these amendments is, 1. General Suffrage. 2. Equal representation in the legislature. 3. An executive chosen by the people. 4. Judges elective or amovable. 5. Justices, jurors, and sheriffs elective. 6. Ward divisions. And 7. Periodical amendments of the constitution.”
"Some men look at constitutions with sanctimonious reverence, and deem them like the arc 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. I knew that age well; I belonged to it, and labored with it. It deserved well of its country. It was very like the present, but without the experience of the present; and forty years of experience in government is worth a century of book-reading; and this they would say themselves, were they to rise from the dead. I am certainly not an advocate for frequent and untried changes in laws and constitutions. I think moderate imperfections had better be borne with; because, when once known, we accommodate ourselves to them, and find practical means of correcting their ill effects. But I know also, that laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths disclosed, and manners and opinions change with the change of circumstances, institutions must advance also, and keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy, as civilized society to remain ever under the regimen of their barbarous ancestors. It is this preposterous idea which has lately deluged Europe in blood….Let us, as our sister States have done, avail ourselves of our reason and experience, to correct the crude essays of our first and unexperienced, although wise, virtuous, and well-meaning councils. And lastly, let us provide in our constitution for its revision at stated periods. What these periods should be, nature herself indicates. By the European tables of mortality, of the adults living at any one moment of time, a majority will be dead in about nineteen years. At the end of that period, then, a new majority is come into place; or, in other words, a new generation. Each generation is as independent as 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; consequently, to accommodate to the circumstances in which it finds itself, that received from its predecessors; and it is for the peace and good of mankind, that a solemn opportunity of doing this every nineteen or twenty years, should be provided by the constitution; so that it may be handed on, with periodical repairs, from generation to generation, to the end of time, if anything human can so long endure.”
