“Every monumental work of the State is measured by cubits. Every cubit is measured by the length of the Aspect-Emperor’s arm. And the Aspect-Emperor’s arm, they say, stands beyond measure. But I say the Aspect-Emperor’s arm is measured by the length of a cubit, and that all cubits are measured by the works of the State. Not even the All stands beyond measure, for it is more than what lies within it, and “more” is a kind of measure. Even the God has His cubits.”

The quote is widely misattributed to Galilei, but is actually from two French scholars, Antoine-Augustin Cournot and Thomas-Henri Martin.

Golden Sayings of Epictetus
Context: Knowest thou what kind of speck you art in comparison with the Universe?—That is, with respect to the body; since with respect to Reason, thou art not inferior to the Gods, nor less than they. For the greatness of Reason is not measured by length or height, but by the resolves of the mind. Place then thy happiness in that wherein thou art equal to the Gods. (33).

Variant translation: The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa.
