"I confess, that I do not entirely approve of this Constitution at present; but, Sir, I am not sure I shall never approve it; for, having lived long, I have experienced many instances of being obliged, by better information or fuller consideration, to change my 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 of others. Most men, indeed, as well as most sects in religion, think themselves in possession of all truth, and that whatever others differ from them, it is so far error. Steele, a Protestant, in a dedication, tells the Pope, that the only difference between our two churches in their opinions of the certainty of their doctrine, is, the Romish Church is infallible, and the Church of England is never in the wrong.

...

If every one of us, in returning to our Constituents, were to report the objections he has had to it, and endeavor to gain Partisans in support of them, we might prevent its being generally received, and thereby lose all the salutary effects and great advantages resulting naturally in our favour among foreign nations, as well as among ourselves, from our real or apparent unanimity. Much of the strength and efficiency of any government, in procuring and securing happiness to the people, depends on opinion, on the general opinion of the goodness of that government, as well as of the wisdom and integrity of its governors.

...

On the whole, Sir, I cannot help expressing a wish, that every member of the Convention who may still have objections to it, would with me on this occasion doubt a little of his own infallibility, and, to make manifest our unanimity, put his name to this Instrument."

- Benjamin Franklin, Speech in the Constitutional Convention, at the Conclusion of Its Deliberations - September 17, 1787
