Confucius said:
17:2 "By nature close together; through practice set apart."
17:3 "It is only those whose knowledge places them in the highest category or whose ignorance places them in the lowest category who do not change."
15:30 "I have spent an entire day without eating, and an entire night without sleeping, so as to think. It was of no use. It is better to learn."
13:30 "To lead the people to war without having taught them is to throw them away."
12:3 "...when doing it is so difficult, how can one be without caution in speaking about it?"
9:16 Standing by a stream, the Master said, "Passing on like this, it never ceases, night or day."
7:3 "Virtue not being cultivated, learning not being discussed, hearing of rightness without being able to follow it, or of what is not good without being able to change it - these are my sorrows."
2:17 "You, shall I teach you what knowledge is? When you know something, to know that you know it. When you do not know , to know that you do not know it. This is knowledge."
2:15 "To learn without thinking is unavailaing; to think without learning is dangerous."
1:16 "One should not grieve that one is unrecognized by others; rather, one should grieve that one fails to recognize others."
