“Many's the man/ who thought himself wise/ but what he needed/ he did not know...”
“He who knows others is wise; he who knows himself is enlightened.”
“The fool doth think he is wise, but the wise man knows himself to be a fool.”
“The wise man is one who, knows, what he does not know.”
“That man is best who sees the truth himself. Good too is he who listens to wise counsel. But who is neither wise himself nor willing to ponder wisdom is not worth a straw.”
“How must he prove himself? What was it they wished to know of him? And what did he know of himself here where loneliness was an unavoidable element of life, and a man must rely solely on himself?”
