"To suppose that many any form of government will secure liberty or happiness without any virtue in the people, is a chimerical idea" James Madison. But John Adams added 'Public Virtue cannot exist in a Nation without private virtue, and public Virtue is the only foundation of a republic."
Explaining more, lets refer to Georges Washington so that to learn: 'Virtue or morality is a necessary spring of popular government, and human rights can only be assured among virtuous people." In a certain sense what also tells Patrick Henry enhance this previous sentence: "A vitiated state of morals, a corrupted public conscience, is incompatible with freedom.". So as warns Benjamin Franklin "Only virtuous people are capable of freedom." Highlighting liberty as a human need, Judge Learned Hand will come to precise that 'Liberty lies in the hearts of men and women. When it dies, no constitution, no law, no court can save it."
If you read all previous quote, why not conclude with Thomas Jeffersonthat " No government can continue good but under the control of the people; and ... theirs minds are to be informed bu education what is right and what is wrong; to be encouraged in habits of virtue and to be deterred from those of vice... These are the inculcation necessary to render the people a sure basis for the structure and order of government.".
However a central point remain Loyalty to the Constitution is stressed by the Preamle stating that "We the people, must seek the blessing of liberty by reverencing the Constitution itself learning and abiding by its precepts of individual self-government and responsibility, being virtuous, and doing good to one another."
