Whatever is done without ostentation, and without the people being witnesses of it, is, in my opinion, most praiseworthy: not that the public eye should be entirely avoided, for good actions desire to be placed in the light; but notwithstanding this, the greatest theater for virtue is conscience.
Shape clay into a vessel;
It is the space within that makes it useful.
Cut doors and windows for a room;
It is the holes which make it useful.
Therefore benefit comes from what is there;
Usefulness from what is not there.
