To me one man is worth ten thousand if he is first-rate.
Everything flows, nothing stays still.
The nature of things is in the habit of concealing itself.
There is a stability in the Universe because of the orderly and balanced process of change, the same measure coming out as going in, as if reality were a huge fire that inhaled and exhaled equal amounts.
All entities move and nothing remains still.
Most people do not take heed of the things they encounter, nor do they grasp them even when they have learned about them, although they suppose they do.
