The Original Quote:
子曰：“由，诲汝，知之乎！知之为知之，不知为不知，是知也。”
Zǐ yuē: “Yóu, huì rǔ, zhī zhī hū! Zhī zhī wéi zhī zhī, bù zhī wéi bù zhī, shì zhī yě.”
English Translation:
The Master said: “You, shall I teach you what it means to know? To know that you know when you know, and to know that you do not know when you do not know—this indeed is true knowledge.”
Key Concepts Explained:
- 知 (zhī): Knowledge or wisdom, but here specifically the self-aware recognition of one’s own cognitive boundaries—an epistemological humility central to Confucian learning.
- 诲 (huì): To teach or instruct, emphasizing the pedagogical relationship between master and disciple, a cornerstone of Confucian education.
- 是知也 (shì zhī yě): “This is wisdom”—a definitive assertion that true intelligence lies not in omniscience but in honest self-assessment.
Cultural Context:
This passage from the Analects (Lunyu 2.17) captures Confucius’s core pedagogical principle of 实事求是 (shí shì qiú shì)—seeking truth from facts. Addressed to his impulsive disciple Zilu (子路), it exemplifies Confucius’s method of 因材施教 (yīn cái shī jiào)—teaching according to the student’s character. In ancient Chinese education, intellectual humility was prized over pretense, as scholars believed that only by acknowledging ignorance could one truly learn. This principle resonates across Chinese philosophy, from Zhuangzi’s parables of unknowing to Neo-Confucian debates on the limits of human understanding, and remains a foundational virtue in East Asian educational culture today.
