George Washington said: “Virtue or morality is a necessary spring of popular government,” and “Human rights can only be assured among a virtuous people.”
Benjamin Franklin said: “Only a virtuous people are capable of freedom.”
James Madison stated: “To suppose that any form of government will secure liberty or happiness without any virtue in the people, is a chimerical [imaginary] idea.”
Thomas Jefferson wrote, “No government can continue good but under the control of the people; and … their minds are to be informed by education what is right and what wrong; to be encouraged in habits of virtue and to be deterred from those of vice … These are the inculcations necessary to render the people a sure basis for the structure and order of government.”
Samuel Adams said: “Neither the wisest constitution nor the wisest laws will secure the liberty and happiness of a people whose manners are universally corrupt. He therefore is the truest friend of the liberty of his country who tries most to promote its virtue.”
Patrick Henry stated that: “A vitiated [impure] state of morals, a corrupted public conscience, is incompatible with freedom.”
John Adams stated: “We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge, or gallantry would break the strongest cords of our constitution as a whale goes through a net. Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.”
Not even the founders of the USA were as delusional as modern political thinkers to think a governmental system could be set without recourse to considering the character and virtue of the constituent population. They were still raving lunatics though.
