Marcus Aurelius
Meditations 4.51
Always run to the short way; and the short way is the natural: accordingly say and do everything in conformity with the soundest reason. For such a purpose frees a man from trouble, and warfare, and all artifice and ostentatious display.
Marcus Aurelius, Meditations 4.51, translated by George Long
Run ever the short way; and the short way is the way of Nature, that leads to all that is most sound in speech and act. For a resolve such as this is a release from troubles and strife, from all mental reservation and affectation.
Marcus Aurelius, Meditations 4.51, translated by C. R. Haines
