"Unless any one who approves of punishment for the promulgation of opinions, flatters himself that he is a wiser and better man than Marcus Aurelius -- more deeply versed in the wisdom of his time, more elevated in his intellect above it -- more earnest in his search for truth, or more single-minded in his devotion to it when found; -- let him abstain from that assumption of the joint infallibility of himself and the multitude, which the great Antoninus made with so unfortunate a result."
- John Stuart Mill
