"Is my understanding equal to this or no? If it is, then I use it for the work, as an instrument put in my hands by the universal nature. If it is not, either I hand over the task to a more skilled labourer,— save only when some further consideration of duty bids me persevere,— or do it as best I may, calling in the aid of one able, with the help of my reason, to effect what is at this juncture opportune and beneficial to the community. For all that I do, whether through my own unaided efforts or with the assistance of another, must tend to this one goal,— the public good and harmony."
Marcus Aurelius, Meditations, VII, 5. (Jackson translation)
Marcus Aurelius Antoninus Augustus was Emperor of Rome, 161-180AD.
