《抱朴子外篇》Vol. 21

Ge Hong (Daoist name Baopuzi) said: People often assume that those with extraordinary courage make great generals, and those who understand governance become capable ministers. Yet consider Zhang Fei and Guan Yu - peerless warriors who ultimately met violent deaths. Scholars like Kong Rong and Bian Rang, though brilliant in writing, failed in practical governance. Conversely, Deng Yu and Ma Yuan were originally field scholars yet excelled in military strategy, while Xiao He and Cao Shen became excellent prime ministers without being classical scholars. This shows how truly difficult it is to judge people's capabilities.

Attempting to test talents through probation risks significant losses, while evaluating through words and appearance may be deceived by superficial impressions. Yet people often oversimplify discernment, believing mere observation suffices - a notion I deeply question. True judgment that distinguishes quality and penetrates appearances requires innate insight beyond forced attainment. Unless one possesses the perceptiveness of sun and moon that hears soundless voices - the clarity of sages - we should employ gradual assessment rather than sudden appointment. Like lending sharp weapons: easy to give, hard to retrieve, with potentially grave consequences. Never assume competence in all matters based on one success.

Those who agree with you may not be useful, while dissenters shouldn't necessarily be ignored. Some counter: Celestial patterns and earthly formations follow discernible rules - mountains and waters reveal their depths, wind and clouds foretell fortune. The wise know jade hides in mountains when trees stay green, and pearls lie beneath unfading shores. Comets foretell sturgeon deaths, eclipses signal qilin battles. We know Hua and Huo mountains' weight without scales, rivers' depth without measurement. A swan's wings and steed's legs promise swiftness before flight; famed swords prove sharpness without use. A calf shows bull-devouring posture, eaglets display sky-conquering stance; lush plants indicate fertile soil, fat fish prove abundant waters. Foxes won't grow tiger tails, nor rats bear elephant tusks. Shuyu's greed manifested at birth, Shiwo's clan-doom appeared in childhood.

This passage explores the difficulty of truly knowing a person, using historical anecdotes and everyday observations to illustrate the limitations of judging people by appearances alone.

Several historical examples are cited: Fan Li (Master Fan) retreated to Lake Tai after recognizing the ominous countenance of King Goujian of Yue; Zhao generals dared not engage in battle against Bai Qi, the famed Qin commander, due to his piercing gaze; King Wen of Zhou determined Jiang Ziya's (Lü Shang) worthiness after a brief conversation beneath a mulberry tree; and Liu Bei (Xuande) immediately confided in Zhuge Liang (Kongming) at their first meeting. The text also mentions Guo Tai, an Eastern Han scholar renowned for accurately assessing people's talents and character.

However, the author (Baopuzi) points out these are exceptional cases. In reality, dignified appearances don't guarantee virtue, frail health doesn't imply stupidity, loud voices don't necessarily indicate courage, and gentle dispositions don't always mean cowardice. External manifestations often contradict inner qualities—just as eyes can see distant stars but not the nape of one's neck, and ears can hear thunder yet miss the footsteps of ants. Even famous ancient physiognomists like Tang Ju, Lü Gong, Fan Kuai, and Xu Fu could only predict lifespan and wealth, failing to discern temperament and aspirations.

The passage concludes by emphasizing that true discernment requires examining not just superficial traits but also speech, conduct, attitudes toward affairs, and views on wealth. Yet even sage rulers struggled to fully understand others—how much more difficult for ordinary people? This discussion reveals the complexity of human nature, warning against simplistic judgments based on appearances.

This passage discusses the difficulty of judging character. Ge Hong (the renowned Daoist scholar known as Baopuzi) uses multiple historical anecdotes to illustrate how even sages often misjudge people.

For instance, a divine archer may pierce the finest autumn hair, yet not always hit the bullseye; though the mother of Shuxiang (a virtuous minister of Jin during the Spring and Autumn period) and the Shen clan had successful cases of discerning character, they couldn’t guarantee accuracy every time. The ancient sage-king Yao (of the Tao-Tang clan), famed for his insight into people, mistakenly employed Gonggong; the Duke of Zhou (Ji Gong), despite his keen perception, misjudged his brother Guanshu; Confucius (Master Ni) could foresee the rise and fall of states yet misread the character of his disciple Tantai Mieming. Jizi of Yanling (Yanzhou) could predict events a thousand years ahead but overlooked extraordinary talents right before his eyes.

Ge Hong particularly admired the method of Guo Tai (styled Linzong), a celebrated Eastern Han scholar, for recognizing talent: he could spot exceptional individuals among ordinary people, like finding a pearl-bearing clam in the depths or identifying luminous jade amidst rubble. For example, Cai Yong (Bojie) could discern that charred paulownia wood was ideal for crafting zithers, while Zhang Heng (Pingzi) recognized that uncarved bamboo could produce exquisite tones. A truly masterful judge of character can penetrate a person’s essence at a glance—whether amid a throng of soldiers or a bustling marketplace—foreseeing their future deeds. This is an ineffable, sublime skill.

If one insists on waiting until a person’s goodness or wickedness is fully manifest, it’s like measuring the length and weight of cloth only after it’s woven—anyone can do that. Why would it require wisdom? Ge Hong emphasizes that true discernment lies in perceiving the subtle to foresee the significant, anticipating development before it takes form.
