Marcus Aurelius
Meditations 11.7
How plain does it appear that there is not another condition of life so well suited for philosophizing as this in which thou now happenest to be.
Marcus Aurelius, Meditations 11.7, translated by George Long
How clearly is it borne in on thee that there is no other state of life so fitted to call for the exercise of Philosophy as this in which thou now findest thyself.
Marcus Aurelius, Meditations 11.7, translated by C. R. Haines
