Meditations 6.21

If any man is able to convince me and show me that I do not think or act right, I will gladly change; for I seek the truth, by which no man was ever injured. But he is injured who abides in his error and ignorance.

Marcus Aurelius, Meditations 6.21, translated by George Long

If any one can prove and bring home to me that a conception or act of mine is wrong, I will amend it, and be thankful. For I seek the truth, whereby no one was ever harmed. But he is harmed who persists in his own self-deception and ignorance.

Marcus Aurelius, Meditations 6.21, translated by C. R. Haines
