Chapter 71 Dyer
Knowing ignorance is strength.
Ignoring knowledge is sickness.
Only when we are sick of our sickness shall we cease to be sick.
The sage is not sick but is sick of sickness.
This is the secret of health.
Chapter 71 Henricks
1. To know you don't know is best.
2. Not to know you [don't] know is a flaw.
3. Therefore, the Sage's not being flawed
4. Stems from his recognizing a flaw as a flaw.
5. Therefore, he is flawless.
Chapter 71 Lau
To know yet to think that one does not know is best;
Not to know yet to think that one knows will lead to difficulty.
It is by being alive to difficulty that one can avoid it.
The sage meets with no difficulty.
It is because he is alive to it that he meets with no difficulty.
Chapter 71 Wu
To realize that our knowledge is ignorance,
This is a noble insight.
To regard our ignorance as knowledge,
This is mental sickness.
Only when we are sick of our sickness
Shall we cease to be sick.
The Sage is not sick, being sick of sickness;
This is the secret of health.
