I imagine a man must have a good deal of Vanity who believes, and a good deal of Boldness who affirms, that all the doctrines he holds are true; and all he rejects are false. And perhaps the same may be said of every Sect, Church and Society of men when they assume to themselves that infallibility which they deny to Popes and Councils. I think Opinions should be judged of by their Influences and Effects.
— Benjamin Franklin
