For one word a man is often deemed to be wise, and for one word he is often deemed to be foolish. We should be careful indeed what we say.
ConfuciusShall I tell you what knowledge is? It is to know both what one knows and what one does not know.
ConfuciusBehave when away from home as though you were in the presence of an honored guest. Employ the people as though you were assisting at an important sacrifice. Do not do to others what you would not like yourself. Then there will be no feelings of opposition to you, whether it is the affairs of a state that you are handling or the affairs of a family.
