Meditations 7.62

Constantly observe who those are whose approbation thou wishest to have, and what ruling principles they possess. For then thou wilt neither blame those who offend involuntarily, nor wilt thou want their approbation, if thou lookest to the sources of their opinions and appetites.

Marcus Aurelius, Meditations 7.62, translated by George Long

Continually reflect, who they are whose favourable testimony thou desirest, and what their ruling Reason; for thus wilt thou not find fault with those who unintentionally offend, nor wilt thou want their testimony, when thou lookest into the inner springs of their opinions and desires.

Marcus Aurelius, Meditations 7.62, translated by C. R. Haines
