Zhīyī bìbiàn 知醫必辨
Knowing Medicine Demands Discrimination by 李冠仙 Lǐ Guànxiān (hào Rúméi lǎorén 如眉老人; c. 1772 – after 1860; Dāntú / Zhènjiāng, Jiāngsū).
About the work
A one-juǎn polemical-doctrinal essay collection by Lǐ Guànxiān, deliberately biàn (discriminative) in genre — i.e. a clarification-and-rebuttal text aimed at correcting the doctrinal one-sidedness Lǐ saw in contemporary practice. The work is structured as short topical essays in which Lǐ stages himself, a rúshēng (Confucian scholar) only secondarily a physician, as the impartial discriminator between the contending JīnYuán and MíngQīng medical schools. The animating polemic is against the uncritical reception of Zhāng Jǐngyuè 張景岳 (the late-Míng exponent of wēnbǔ warming-and-tonifying) and against the misuse of Wú Yòukě’s 吳又可 Wēnyì lùn 溫疫論 by under-qualified contemporaries. The text is also designed as instruction for Lǐ’s own children and grandchildren — jiāxùn (family instruction) for the literate-medical Lǐ household.
Prefaces
The text opens with two self-prefaces. The first is dated 道光二十八年春三月 (1848 spring), signed “Rúméi lǎorén zìxù yú Hányítáng” 如眉老人自序於含飴堂 (“the Old Man of Rúméi, written in the Hányí Hall”). Lǐ frames the text as one written reluctantly — “Yú qǐ hàobiàn zāi, yú bùdéyǐ yě” 予豈好辨哉，予不得已也! (“Do I love discrimination? — I have no choice in the matter!”), self-consciously echoing Mèngzǐ’s famous “yú qǐ hàobiàn zāi”. The polemical map is laid out: from Wáng Shūhé 王叔和 of the Jìn down, every commentator has had a piān (one-sidedness) — Liú Wánsù (河間) toward liáng (cooling), Zhū Dānxī toward yǎngyīn (yīn-nourishing), Lǐ Dōngyuán toward wēnbǔ (warming-tonifying), Zhāng Jǐngyuè most one-sided of all. A skilful physician, Lǐ argues, draws on each school as the clinical situation requires; the present generation, however, knows of the Jǐngyuè quánshū only by hearsay, extracts two warming-tonifying prescriptions from it, and uses them indiscriminately. The second zìxù records the urging of a visitor that Lǐ expand the collection by ten or twenty more essays for printing, and Lǐ’s refusal — he does not want to be among those who “abuse the pear-and-jujube wood” by publishing for fame.
Abstract
Lǐ Guànxiān (Wénróng 文榮, zì Yúshū 餘墅, hào Guànxiān 冠仙 / Rúméi lǎorén 如眉老人) was a Dāntú 丹徒 (Zhènjiāng) physician and contemporary of 王九峰 Wáng Jiǔfēng in the same locality. The catalog meta gives him as 清; the internal dating of the self-preface is Dàoguāng 28 (1848) and Lǐ continued writing through the 1850s, supporting a composition window 1848–1855 for the present collection.
The work is a key primary source for the mid-19th-century critique of Jǐng-yuè-school wēnbǔ prescribing, which Lǐ frames not as a wholesale rejection of the Jǐngyuè corpus (his polemic is explicitly that the Jǐngyuè quánshū itself uses many other strategies and that the wēnbǔ extraction is the abuse, not the original doctrine) but as an attack on the abuse of one strand of it. The same argument, in a more aggressive register, would reappear in the Wēnbìng synthesis of 王士雄 Wáng Mèngyīng. Lǐ’s parallel critique of Wú Yòukě’s Wēnyì lùn — “běn bù chéng shū” (“not even properly a book”), abused by ignorant practitioners with disastrous results — is unusual among 19th-century yīhuà and worth noting as a counter-current to the dominant Wēnbìng-school reception of Wú. Lǐ’s clinical authority is documented by KR3ep060 Lǐ Guànxiān yīàn, whose case-narratives illustrate the doctrinal positions defended here. Not in CBDB.
