I want to start with two of my favorite quotes from the founding era. Here’s the first and most famous, from Thomas Jefferson:
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.–That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed.
That’s of course the key text of the Declaration of Independence. And then here’s John Adams, in his Letter to the Massachusetts Militia:
We have no Government armed with Power capable of contending with human Passions unbridled by morality and Religion. Avarice, Ambition Revenge or Galantry, 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.
