Rectification of names
"If language is not correct, then what is said is not what is meant;
if what is said is not what is meant, then what must be done remains undone;
if this remains undone, morals and art will deteriorate;
if justice goes astray, the people will stand about in helpless confusion.
Hence there must be no arbitrariness in what is said.
This matters above everything."
Confucius
