士人读书明理,期于世有所济,立功名以见重当时,此体用兼备之学也。若学成理明,
无意立名,而慈祥之念,无时无地不期于济世,此其品诣不又加人一等乎哉?余观伦声许生
《外科证治》一书而有感焉。伦声少嗜学,经史而外,旁及诸子百家,一名一艺之微,手披
目览,各有所得。山居数十年,怡然自乐,不肯以学自炫。间因良善之家式微,为之指示趋
吉修方。或婴孩疾痛,时医束手,为之施送药饵,无不速效,人始奇之。由是名噪于士大夫
间。延访遂众,辞之不获,已择近地大山水处,始一命驾。人与之款洽,言皆经济文章,绝
不及他事。庚寅春,余遇于皖江郡城,年逾八十,白发萧疏,神明弗衰,非学养之醇耶。
嗣余权篆芜关,通尺素书,邀其掉扁舟冒雪而来,围炉谈论竞日,叩其生平阅历,如郡县学
宫添建文峰高阁,不周岁而人文蔚发,是何神速,伦声则谦未遑。谓吉凶皆盈虚消长自然道
理,一有走避,必干造物之忌。若乃胜地名区,善人多则吉祥自生,趋吉之说,皆事之适然
相合,非尽关人力也。其言似谦,其实有至理存焉。临别检行箧,余见有《外科证治》一书
,则续成其故友毕苍霖未竞之业。其部首分别阴阳证治,其卷末并列急治五条,共书五卷,
自记甚悉,余益叹其品学之优也。书成,不独擅其美,必推善于创始之良友。其所分门列类
者,皆二十余年历试活人无算之实学,非借着书立说以求声誉者比。余将远别数千里外,此
书若仍携归,恐久而失传,为借抄副本付剞劂,以质世之精医理者;虽曰小道,亦足见伦声
所学之绪余,与济人之素心云尔。
生名克昌,和州国学生,伦声其字也。
时道光岁次辛卯夏月督榷使者云梦程怀 书于上海榷署
Scholars study the classics to understand principles, hoping to contribute to society, establish merit and fame to be respected by their contemporaries; this is a learning that integrates substance (Ti) and function (Yong). If one has achieved scholarly success and clarity of principle, yet has no intention of seeking fame, while possessing a compassionate mind that constantly desires to save the world at all times and places, is not such a person's moral attainment even higher than others? I was moved after reading Mr. Lunsheng Xu's book "Waike Zhengzhi" (Surgical Treatment Verification).
Lunsheng loved learning since his youth. Beyond the Classics and History, he extensively studied the Hundred Schools of Thought. Regarding even minor matters of nomenclature or skills, he read them with his own hands and eyes, gaining insights from each. Living in the mountains for decades, he was content and happy, refusing to show off his learning. Occasionally, when virtuous families fell into decline, he would guide them on how to seek auspiciousness and prescribe formulas. When infants suffered from illnesses that contemporary physicians could not treat, he would administer medicines, achieving rapid effects without fail, which led people to marvel at him. Consequently, his reputation spread among the scholar-officials. As invitations for consultation became numerous and he could not refuse, he eventually chose to settle near a large city in a scenic area and agreed to practice medicine. Those who interacted with him discussed essays on statecraft and governance, never mentioning trivial matters.
In the spring of the Gengyin year, I met him in the prefectural city of Wanjiang. He was over eighty years old, with sparse white hair, yet his spirit remained vigorous. Was this not due to his profound cultivation of learning and character? Later, while acting as the supervisor of the Wuguan customs, I corresponded with him via letters, inviting him to travel by boat through the snow. We sat around a stove discussing for the whole day. When I asked about his life experiences, he mentioned that just as adding a high pavilion to the local academy can lead to a flourishing of culture within a year, so too does virtue bring its own rewards. He humbly claimed he had no time for such achievements. He stated that good and bad fortune are natural laws of waxing and waning; attempting to evade fate would offend the Creator. In renowned scenic areas, where there are many virtuous people, auspiciousness arises naturally. Thus, the concept of "seeking auspiciousness" is merely a coincidence of events, not entirely dependent on human effort. His words seemed humble but contained profound truth.
Upon parting, while inspecting his luggage, I saw a copy of "Waike Zhengzhi" (Surgical Treatment Verification), which was actually the completion of the unfinished work of his late friend Bi Canglin. The first section distinguishes Yin and Yang syndromes for treatment, and the final volume lists five emergency treatments. The book consists of five volumes, with detailed self-explanations, further confirming my admiration for his excellent character and scholarship. Upon completing the book, he did not claim sole credit but attributed the merit to his pioneering friend. The categories and classifications he established were based on over twenty years of practical experience saving countless lives, unlike those who write books solely to gain reputation. As I was about to depart for thousands of miles away, fearing the book might be lost if taken back, I borrowed a copy to have it printed, presenting it to experts in medical theory for review. Although surgery is considered a "minor path," it sufficiently demonstrates the remnants of Lunsheng's learning and his original intention to help others.
The gentleman's name was Kechang, a Guosheng (Student of the State Academy) from Hezhou, and Lunsheng was his courtesy name.
