Chapter 71: Knowing What You Do Not Know
Chapter 71 is Laozi's compact meditation on epistemic humility. The real illness is not ignorance itself but false certainty about what one does not understand.
📖 Definition
Chapter 71 says the highest knowledge includes knowing what you do not know. The deeper sickness is false certainty, not simple ignorance.

Original Chinese
知不知，上；
不知知，病。
夫唯病病，是以不病。
聖人不病，以其病病，是以不病。
English Rendering
To know what you do not know is best.
Not to know, yet think you know, is sickness.
Only by recognizing sickness as sickness can one be free of sickness.
The sage is free of sickness because the sage recognizes sickness as sickness and so is not sick.
The Best Kind of Knowing
知不知，上 — “To know what you do not know is best.”
Laozi treats humility not as weakness but as a superior form of intelligence.
The Illness of False Knowledge
不知知，病 — “Not to know, yet think you know, is sickness.”
This is worse than ordinary ignorance because it hides from correction.
Why Recognition Heals
Only by recognizing the sickness for what it is can one stop being ruled by it. Clarity begins with accurate diagnosis.
The Sage Is Not Sick
The sage is not magically immune to error. The sage is free because the tendency toward false certainty is seen early and not protected.
Key Takeaways
- Humility is treated as a higher form of knowledge
- The real illness is false certainty, not mere ignorance
- Accurate diagnosis is already part of healing

Laozi describes the Tao as vague and unclear, yet containing form, substance, and essence. True virtue follows the Tao alone, not intellectual understanding.
- Chapter 28Chapter 28: Knowing the Male
Chapter 28 is a chapter of reversals: know strength but keep to receptivity, know brightness but keep to obscurity, know honor but keep to humility. Laozi's ideal is not ignorance but disciplined refusal of self-exaltation.
- Chapter 39Chapter 39: The Unity of Things
Chapter 39 links cosmic order and political order through 'the One.' Everything stands only because it rests on a prior unity, which is why Laozi says the high must take the low as its foundation.
