limit and imprison it. Their eagerness to acquire knowledges
and enrich the memory was further evident from the following
circumstances: Once, when I was writing something concerning things
to come, and they were at a distance, so that they could not look into

a still greater distance, yet kept stopping, being desirous of knowing
what I had written. Such is their eager desire for knowledges.
