Marcus Aurelius
Meditations 7.24
A scowling look is altogether unnatural; when it is often assumed, the result is that all comeliness dies away, and at last is so completely extinguished that it cannot be again lighted up at all. Try to conclude from this very fact that it is contrary to reason. For if even the perception of doing wrong shall depart, what reason is there for living any longer?
Marcus Aurelius, Meditations 7.24, translated by George Long
An angry scowl on the face is beyond measure unnatural, and when it is often seen there, all comeliness begins at once to die away, or in the end is so utterly extinguished that it can never be rekindled at all. From this very fact try to reach the conclusion that it is contrary to reason. The consciousness of wrong-doing once lost, what motive is left for living any more?
Marcus Aurelius, Meditations 7.24, translated by C. R. Haines
