I have never seen one who really loves goodness or one who really hates wickedness. One who really loves goodness will not place anything above it. One who really hates wickedness will practice goodness in such a way that wickedness will have no chance to get at him. Is there anyone who has devoted his whole strength to doing good for even as long as a single day? I have not seen anyone give up such an attempt because he had not the strength to go on. Perhaps there is such a case, but I have never seen it.

The superior man thinks always of virtue; the common man thinks of comfort.

Every truth has four corners: as a teacher I give you one corner, and it is for you to find the other three.

Shall I tell you what knowledge is? It is to know both what one knows and what one does not know.

The main object of conciliation lies in reaching a solution to a case based upon morals and with a warm heart.

The superior man will watch over himself when he is alone. He examines his heart that there may be nothing wrong there, and that he may have no cause of dissatisfaction with himself.

What you do not wish upon yourself, extend not to others.
