As a saint, Confucius certainly won't lie-even white lies can have disadvantages.

Confucius said nothing because he was considerate. He should not only deal with existence and non-existence, truth and falsehood, but also deal with good and bad, emotion and reason. He has to make not only factual judgment, but also value judgment, so he refuses to be satisfied with the general factual statement, and also considers the various consequences that may follow after the factual statement.
