It is a bad plan that admits of no modification.
— Publilius Syrus

I know of nothing sublime which is not some modification of power.
Edmund Burke modification quote

Republics abound in young civilians who believe that the laws make the city, that grave modifications of the policy and modes of living and employments of the population, that commerce, education and religion may be voted in or out; and that any measure, though it were absurd, may be imposed on a people if only you can get sufficient voices to make it a law. But the wise know that foolish legislation is a rope of sand which perishes in the twisting; that the State must follow and not lead the character and progress of the citizen; that the form of government which prevails is the expression of what cultivation exists in the population which permits it. The law is only a memorandum.
— Ralph Waldo Emerson

If in the opinion of the People, the distribution or modification of the Constitutional powers be in any particular wrong, let it be corrected by an amendment in the way which the Constitution designates. But let there be no change by usurpation; for though this, in one instance, may be the instrument of good, it is the customary weapon by which free governments are destroyed.
— George Washington

Common sense is only a modification of talent. Genius is an exaltation of it. The difference is, therefore, in degree, not nature.
