Monday, September 17, 1787, was the last day of the Constitutional Convention.
Pennsylvania delegate Benjamin Franklin, one of the few Americans of the time with international repute, wanted to give a short speech to the Convention prior to the signing of the final draft of the Constitution.
Too weak to actually give the speech himself, he had fellow Pennsylvanian James Wilson deliver thespeech. It is considered amasterpiece:
I confess that there are several parts of this constitution which I do not at present approve, but I am not sure I shall never approve them: 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. Steele a Protestant in a Dedication tells the Pope, that the only difference between our Churches in their opinions of the certainty of their doctrines is, the Church of Rome is infallible and the Church of England is never in the wrong. 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 (“There is only me who is always right.”).”
Seems especially relevant in light of the recent Kim Davis news.
