For having lived long, I have experienced many instances of being obliged by better information, or fuller consideration, to change opinions even on important subjects, which I once thought right, but found to be otherwise. It is therefore that the older I grow, the more apt I am to doubt my own judgment, and to pay more respect to the judgment of others. Most men indeed as well as most sects in Religion, think themselves in possession of all truth, and that wherever others differ from them it is so far error… But though many private persons think almost as highly of their own infallibility as of that of their sect, few express it so naturally as a certain French lady, who in a dispute with her sister, said “I don’t know how it happens, Sister but I meet with no body but myself, that’s always in the right — Il n’y a que moi qui a toujours raison.
In these sentiments, Sir, I agree to this Constitution with all its faults, if they are such; because I think a general Government necessary for us, and there is no form of Government but what may be a blessing to the people if well administered, and believe farther that this is likely to be well administered for a course of years, and can only end in Despotism, as other forms have done before it, when the people shall become so corrupted as to need despotic Government, being incapable of any other.
—Benjamin Franklin, Speech before the Constitutional Convention, Sept. 17, 1787, recorded by James Madison, Debates in the Federal Convention of 1787
