Confucius
If a man remembers what is right at the sign of profit, is ready to lay down his life in the face of danger, and does not forget sentiments he has repeated all his life when he has been in straitened circumstances for a long time, he may be said to be a complete man.
While you are not able to serve men, how can you serve spirits [of the dead]?...While you do not know life, how can you know about death?
