“A foolish consistency is the hobgoblin of little minds, adored by little statesman and philosophers and divines. With consistency a great soul has simply nothing to do. Speak what you think now in hard words and tomorrow speak what tomorrow thinks in hard words, though it contradict everything you think today. ” Emerson, Self-Reliance

“Ah, you’re trying to refute me by quoting things I’ve said or written myself. But I live from one day to the next! If something strikes me as probable, I say it; and that is how, unlike everyone else, I remain a free agent.” Cicero, Discussions at Tusculum

I don’t think there is a more impressive thing to do intellectually than turn over a long-held a opinion in light of new evidence. And maybe free agency isn’t the right metaphor any longer because what I really think he’s talking about is having a higher loyalty. That is, being ok with the embarrassment contradicting yourself in exchange for working towards the truth. Being consistently inaccurate to be constantly accurate.
