Original Text
Knowing that you still have what you do not know is the best. Not knowing yet thinking you know is truly bad. The person of the Way has no flaws because he treats flaws as flaws; precisely because he treats flaws as flaws, he has no flaws.
Guide
The wise fear not seeing their own flaws; they seek them out and correct them, thus never troubled by them. In contrast, the foolish dread exposing their flaws, spending their days in anxious pretense to cover them up. People should rightly recognize their shortcomings and bravely face their defects.Analysis
In this chapter, Laozi discusses one of the weaknesses of human nature: pretending to know what one does not, which he considers a sickness, manifested as stubborn self-righteousness. In earlier chapters, Laozi proposed the idea that "those who know themselves are enlightened," telling us that truly understanding oneself is the mark of wisdom. Therefore, only by genuinely knowing ourselves can we avoid being opinionated and self-righteous.
Laozi said: "To know that you do not know is superior; to not know but think you know is a disease." In this statement, "knowing that you do not know" means being aware of your own ignorance, while "not knowing but thinking you know" means mistaking ignorance for knowledge. The meaning is that recognizing your own ignorance is wise, while pretending to know what you do not is a flaw. The thought expressed here by Laozi easily reminds us of a saying by the Greek philosopher Socrates: the wisest and most knowledgeable person is the one who admits their own ignorance. Confucius also said: "To know what you know and to know what you do not know—that is true knowledge." This means that both knowing you have knowledge in a certain area and knowing you lack it are forms of knowledge. Whether it is Socrates or Confucius, both emphasize that people must have self-awareness.
After analyzing those who are "unaware of themselves," Laozi presents the sage's "freedom from affliction" before the world as a contrast, making the result self-evident. What about the sage? The following sentence provides us with the answer.
"The sage is not flawed because he sees flaws as flaws. It is precisely because he sees flaws as flaws that he is without flaw." The first "flaw" is a verb, meaning to detest or abhor; the second "flaw" is a noun, originally meaning disease, but here referring to those who are ignorant yet think they know, incorrigibly foolish. Why does Laozi say the sage has no flaws? In his view, the sage is not without shortcomings, but he acknowledges them and strives to correct them, so over time he becomes flawless. This is what Laozi means by "without flaw," which should be understood as being mentally and spiritually unmasked by external things, in other words, able to see through everything. Thus, the sage values self-knowledge and promptly corrects his faults, rather than being self-righteous or obstinate, so his virtue gradually perfects, making him a model for others to emulate.
No one in the world can exist in isolation; everyone inevitably connects with others, society, and nature. Each of us is a part of the whole world. As individuals within this whole, how can we live in harmony with others? The first thing we must do is overcome the weakness of self-righteousness.
If a person fails to position themselves correctly and sets goals that do not suit them, yet still strives to achieve those goals with what they believe is strong willpower, the consequences may be more terrifying than having no goals at all. Stubbornness and lack of self-awareness bring not the happiness of success but the pain of failure, and such blind psychology can exact a heavy price. For example, when pursuing success in career or love, we often charge forward recklessly, which is good in itself, but once we take the wrong path and refuse to listen to good advice, the resulting consequences can be dreadful.
Arrogant people are often reckless, and the reckless frequently unintentionally hurt others' self-esteem, while also getting hurt themselves due to this carelessness. Some people are not necessarily untalented; the reason they cannot display their talents is that they are too arrogant. Few are willing to trust a person who exaggerates, and even fewer are willing to help someone who speaks rudely.
Arrogant people are often rude; rude people are often isolated; isolated people often end in failure. Those with a general's demeanor tend to be humble, while the arrogant always exude a pettiness. The worst are those who are both arrogant and incompetent—arrogance makes them dare anything, incompetence turns everything into chaos. Sometimes, even when the arrogant realize they are wrong, they stubbornly cling to their views and actions, which is what most irritates those around them. Stubbornness is a tool for the arrogant to get what they want—the more others oppose, the more they insist. This stubbornness repels others. Over time, they find everyone avoiding them.
A person who is arrogant and complacent is bound to be stubborn and self-opinionated. Faced with someone who is arrogant and overbearing, we need not argue with them; time will prove their true worth, and facts will punish their ignorance and absurdity.
Whether in personal conduct or in work, we must adhere to the principle that modesty helps one progress, while pride makes one lag behind.
One must understand that everything in the world is in constant flux; only by adjusting one's plans and strategies in accordance with these changes can one seize the initiative at every turn and remain invincible.
Those who are stubborn and self-willed are just the opposite. Their greatest flaw is self-righteousness, believing their own judgments are flawless, thus often acting arrogantly and willfully. They tend to overestimate themselves and underestimate their opponents, making them easily deceived by superficial appearances, leading to misjudgment and failure.
