人之死，误于医家者，十之三；误于病家者，十之三；误于旁人涉独医者，亦十之三；
盖医
之为道，乃通天彻地之学，必全体明，而后可以治一病。若全体不明，而偶得一知半解，举
以试人，轻浅之病，或能得效；至于重大疑难之症，亦以一偏之见，妄议用药，一或有误，
生死立判矣。间或偶然幸中，自以为如此大病，犹能见功，益复自信，以后不拘何病，辄妄
加议论至杀人之后，犹以为病自不治，非我之过，于是终身害人而不悔矣，然病家往往多信
之者，则有故焉。盖病家皆不知医之人，而医者写方即去，见有稍知医理者，议论凿凿，又
关切异常，情面甚重，自然听信。谁知彼乃偶然翻阅及道听途说之谈，彼亦未尝审度，从我
之说，病者如何究竟，而病家已从之矣。又有文人墨客及富贵之人，文理本优，偶尔检点医
书，自以为已有心得。旁人因其平日稍有学问品望，倍加信从；而世之医人，因自己全无根
柢，辨难反出其下，于是深加佩服。彼以为某乃名医，尚不如我，遂肆然为人治病，愈则为
功，死则无罪。更有执一偏之见，恃其文理之长，更着书立说，贻害后世。此等之人，不可
胜数。嗟乎！古之为医者，皆有师承；而又无病不讲，无方不通，一有邪说异论，则引经据
典以折之，又能实有把持，所治必中，故余人不得而矣其末议。今之医者，皆全无本领，一
书不读，故涉猎医书之人，反出而临乎其上，致病家亦鄙薄医者，而反信夫涉猎之人，以致
害人如此。此其咎全在医中之无人，故人人得而操其长短也。然涉猎之人，久而自信益真，
始误他人，继误骨肉，终则自误其身。我见甚多，不可不深省也。
人的死亡，因医生误治而导致的，占十分之三；因家属处理不当而导致的，占十分之三；因旁人在医学上浅尝辄止、妄加议论而导致的，也占十分之三。
大抵医学这门学问，是贯通天地的高深之学，必须全面通晓医理，然后才能治疗一种疾病。如果整体医理不明，只是偶然获得一知半解，就拿来尝试救治病人，对于轻浅的疾病，或许能取得疗效；但对于重大疑难的病症，却以片面的见解，胡乱议论用药，一旦有误，生死立刻就会决定。
偶尔有侥幸成功的，便自以为如此严重的病都能见效，更加自信，以后不管什么病，都随意妄加议论。到了杀人的地步，还认为病是自己无法治愈的，不是我的过错，于是终身害人而不知悔改。然而，病人家属往往多相信这些人，这是有原因的。因为病人家属都是不懂医的人，而医生开完方子就离开了，这时如果有稍微懂点医理的人在旁边，议论得头头是道，又显得非常关切，情面很重，家属自然就会听信。
谁知道那些人不过是偶然翻阅医书或道听途说来的谈资，他们自己也没有审度清楚，听从他们的说法后，病人的最终结果如何，而病人家属就已经盲从了。又有文人墨客以及富贵之人，文章辞藻本优秀，偶尔检阅医书，自以为已有心得。旁人因为他们在平时稍有学问和声望，加倍信任顺从；而世间的医生，因为自己全无根基，辩论反而处于下风，于是深深佩服。那些人便以为某某是名医，还不如我，于是坦然地为人治病，治好了算是功劳，治死了也没有罪责。更有甚者，坚持片面的见解，倚仗自己的文笔长处，更著书立说，贻害后世。这样的人，数不胜数。
唉！古代的行医者，都有师承渊源；而且没有不研究的病，没有不通晓的方剂，一旦遇到邪说异论，就能引经据典来驳斥它，又能切实掌握病情，所治必中，所以其他人不能发表非议。现在的医生，都全无本领，一本书都不读，所以那些涉猎医书的人，反而出来凌驾于他们之上，致使病人家属也鄙薄真正的医生，反而相信那些涉猎之人，导致像这样害人。这其中的过错全在于医学界缺乏真正的人才，所以人人都可以指责其长短。
然而，那些涉猎之人，时间久了自信越发坚定，开始误导他人，接着误导骨肉亲人，最终则误导自身。我见到的例子很多，不可不深刻反省啊。
Of those who die, three-tenths are misled by physicians; three-tenths are misled by the patients' families; and three-tenths are misled by laypeople with superficial medical knowledge.
The practice of medicine is a profound discipline that connects heaven and earth. One must have a comprehensive understanding of the entire system before being able to treat even a single disease. If one lacks a holistic understanding but possesses only fragmentary knowledge, and attempts to use this on patients, it might yield results for mild or superficial conditions. However, for major and difficult cases, relying on a partial perspective to arbitrarily prescribe medication can lead to immediate fatal consequences if an error occurs.
Occasionally, there may be accidental successes, leading individuals to believe that since they could achieve results in such severe cases, their confidence grows. Subsequently, regardless of the condition, they engage in arbitrary speculation. Even after causing death, they maintain that the disease was incurable and not their fault, thus harming others throughout their lives without repentance. Nevertheless, patients' families often trust these individuals due to specific reasons. Since family members typically lack medical knowledge, and physicians leave after prescribing, when someone with slightly more medical theory speaks up with assertive arguments and apparent deep concern, the emotional weight naturally sways them to listen.
Who knows that these individuals merely rely on occasional reading or hearsay? They themselves do not carefully evaluate the ultimate outcome of following their advice, yet the families blindly comply. Furthermore, literati and wealthy individuals, who are already skilled in rhetoric, may occasionally review medical texts and believe they have gained insights. Others, respecting their usual scholarship and reputation, trust them even more. Physicians of the time, lacking any solid foundation, find themselves outmatched in debate and thus deeply admire these amateurs. Believing that even famous physicians are inferior to them, these amateurs freely treat patients, claiming credit for cures and accepting no blame for deaths. Some, clinging to one-sided views and leveraging their literary skills, go so far as to write books and propagate theories, harming future generations. Such people are countless.
Alas! Ancient practitioners all had formal lineages of instruction. They studied every disease and mastered every formula. When confronted with heterodox theories, they would cite classics to refute them. Moreover, they possessed genuine clinical competence, ensuring accurate treatments, which prevented others from offering frivolous criticism. Modern physicians, however, often lack skill and read nothing. Consequently, those with superficial knowledge rise above them, causing families to despise true doctors and instead trust the amateurs, resulting in such widespread harm. The fault lies entirely within the medical profession for lacking competent personnel, allowing anyone to criticize its shortcomings.
However, these amateurs become increasingly confident over time. Initially misleading others, then misleading their own kin, and finally misleading themselves. I have witnessed many such cases and urge deep reflection.
