Pray thee, spare, thyself at times: for it becomes a wise man sometimes to relax the high pressure of his attention to work.

Now this relaxation of the mind from work consists on playful words or deeds. Therefore it becomes a wise and virtuous man to have recourse to such things at times.

A wise man proportions his belief to the evidence.

From the errors of others, a wise man corrects his own.

Knowledge is the treasure of a wise man.

It is best for the wise man not to seem wise.
