The superior man, extensively studying all learning, and keeping himself under the restraint of the rules of propriety, may thus likewise not overstep what is right.
ConfuciusGreat as heaven and earth are, men still find some things in them with which to be dissatisfied. Thus it is that, were the superior man to speak of his way in all its greatness, nothing in the world would be found able to embrace it, and were he to speak of it in its minuteness, nothing in the world would be found able to split it.
Confucius
