“Real knowledge is to know the extent of one's ignorance.”
Confucius (-551–-479 BC) Chinese teacher, editor, politician, and philosopher
“The utmost extent of man's knowledge, is to know that he knows nothing.”
These words, sometimes attributed to Addison, are not found in his works, but in The Spectator, no. 54, he translates the following words of Socrates, as quoted in Plato's Apology: "When I left him, I reasoned thus with myself: I am wiser than this man, for neither of us appears to know anything great and good; but he fancies he knows something, although he knows nothing; whereas I, as I do not know anything, so I do not fancy I do. In this trifling particular, then, I appear to be wiser than he, because I do not fancy I know what I do not know."

The Analects, The Doctrine of the Mean
Context: The way which the superior man pursues, reaches wide and far, and yet is secret. Common men and women, however ignorant, may intermeddle with the knowledge of it; yet in its utmost reaches, there is that which even the sage does not know. Common men and women, however much below the ordinary standard of character, can carry it into practice; yet in its utmost reaches, there is that which even the sage is not able to carry into practice. Great 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.
