我皇上御极五十年，惠政频施，仁风洋溢，民尽雍熙，物无夭札，固无藉于《灵枢》《
素问》之书，而后臻斯世于寿域也。虽然，先文正公有言∶不为良相，当为良医。乃知有圣
君不可无良相，而良医之权又与良相等，医之一道，又岂可忽乎哉！自轩辕、岐伯而下，代
有奇人，惟长沙张仲景为最着。厥后，或刘或李或朱，并能以良医名，然其得力处，不能不
各循一己之见，犹儒者尊陆尊朱，异同之论，纷纷莫一。
越人张景岳，盖医而良者也。天分既高，师古复细，是能融会乎百家，而贯通乎诸子者
，名其书曰“全”，其自负亦可知矣。他不具论，观其《逆数》一篇，逆者得阳，顺者得阴
，降以升为主，此开阴阳之秘，盖医而仙者也。世有以仙为医，而尚不得谓之良哉？而或者
曰∶医，生道也；兵，杀机也。医以阵名，毋乃不伦乎？不知元气盛而外邪不能攻，亦由壁
垒固而侵劫不能犯也。况兵之虚实成败，其机在于俄顷；而医之寒热攻补，其差不容于毫发
，孰谓医与兵之不相通哉？若将不得人，是以兵与敌也；医不得人，是以人试药也。此又景
岳以阵名篇之微意也。
是书为谦庵鲁方伯任粤时所刻，纸贵五都，求者不易。转运使贾君，明于顺逆之道，精
于升降之理，济世情殷，重登梨枣。予于庚寅孟冬，奉天子命，带星就道，未获观其告竣。
阅两月，贾君以札见示，《景岳全书》重刻已成，命予作序。余虽不敏，然以先文正公良医
良相之意广之，安知昔日之张君足为良医，而异日之贾君不为良相，以佐我皇上万寿无疆之
历服耶？故为数语以弁卷首。

我皇上的统治已五十年，仁政频繁施行，仁爱之风洋溢四海，百姓安居乐业，万物不受早夭之灾，这本来就不需要依靠《灵枢》和《素问》这两部医书，就能使这个世界达到长寿的境界。虽然如此，先前的文正公曾说：“如果不能做优秀的宰相，就应当做优秀的医生。”由此可知，有圣明的君主就不能没有优秀的宰相，而优秀医生的权柄又与优秀宰相相当，医学这一门学问，又怎么可以忽视呢！自从轩辕黄帝、岐伯以来，历代都有杰出的人才，只有长沙人张仲景最为著名。此后，无论是刘完素、李东垣还是朱丹溪，都能以优秀医生的名声著称，然而他们得力之处，不能不各自遵循自己的见解，就像儒家学者尊崇陆九渊或朱熹一样，关于异同的争论，纷纷扬扬，没有统一的标准。
越地人张景岳，是位优秀的医生。他天资聪颖，师法古人又细致入微，因此能够融会贯通百家学说，贯通诸子百家的思想，给他的书命名为“全”，他的自负也可以知道了。其他的不详细论述，看他的《逆数》一篇，逆者得阳，顺者得阴，以下降为主但强调上升的作用，这是揭示阴阳的秘密，可以说是医术高超如仙的人。世上有人把仙人当作医生，难道还不能称为优秀吗？或许有人说：医学，是救生的道路；兵法，是杀机的所在。用军队（阵）来命名篇章，岂不是不伦不类吗？不知道元气旺盛则外邪不能侵犯，也如同城墙坚固则侵略劫掠不能犯境。况且兵法的虚实成败，其关键在于瞬间；而医学的寒热攻补，其差错不容许有毫发之差，谁说医学与兵法不相通呢？如果将领不得其人，那就是拿士兵去送死；医生不得其人，那就是拿病人试药。这又是景岳用“阵”来命名篇章的深意啊。
这本书是谦庵鲁方伯在担任广东巡抚时刊刻的，纸张昂贵于五大都市，求书的人不容易得到。转运使贾君，精通顺逆的道理，精于升降的原理，怀着救济世人的殷切心情，再次重新雕版印刷。我在庚寅年孟冬，奉天子之命，带着星夜兼程上路，未能看到它完成。过了两个月，贾君写信给我看，《景岳全书》重刻已经完成，让我作序。我虽然不聪明，但是根据先文正公关于良医良相的意思推广开来，怎知昔日的张君不足以成为良医，而未来的贾君不会成为良相，来辅佐我皇上万寿无疆的历服呢？所以写了几句话放在卷首。
闽浙制使沈阳范时崇撰
The reign of our august sovereign has reached fifty years. Benevolent policies have been frequently implemented, and the wind of benevolence permeates everywhere. The people are living in harmony and prosperity, and all things are free from premature death. Indeed, there is no need to rely on the *Ling Shu* (Spiritual Pivot) and *Su Wen* (Basic Questions) to bring this world to an age of longevity. Nevertheless, as the late Wenzheng Gong once said: "If one cannot be a good prime minister, one should become a good physician." This implies that with a sage ruler, there must be capable ministers; and since the authority of a good physician is comparable to that of a good minister, how can the art of medicine be neglected? Since the times of Xuanyuan (Yellow Emperor) and Qibo, outstanding figures have appeared in every generation, but Zhang Zhongjing of Changsha is the most renowned. Later, whether it was Liu [Wansu], Li [Dongyuan], or Zhu [Danxi], all were famous as good physicians. However, their strengths inevitably stemmed from their own individual perspectives, much like Confucian scholars revering either Lu [Jiuyuan] or Zhu [Xi], leading to endless debates on similarities and differences without a unified standard.
Zhang Jingyue of Yue is a good physician. With high natural endowment and meticulous study of ancient texts, he is able to integrate the teachings of a hundred schools and penetrate the insights of various philosophers. Naming his book "Quan" (Complete/All-Encompassing), his self-confidence is evident. Without discussing other aspects, let us look at his chapter "Ni Shu" (Reverse Numbers). In this context, "reverse" yields Yang, and "smooth" yields Yin; while descending is the norm, ascending is the primary focus. This reveals the secrets of Yin and Yang, making him a physician whose skill is akin to immortality. If one considers such a person a physician, can they not be called "good"? Some might argue: Medicine is the way of life; military strategy is the mechanism of killing. Is it inappropriate to name chapters using military terms like "formation" (Zhen)? One does not realize that when Yuan Qi (Original Qi) is abundant, external pathogens cannot attack, just as fortified walls prevent invasion. Moreover, the success or failure of military formations depends on moments, whereas errors in medical treatment regarding cold, heat, draining, and tonifying allow for no slightest deviation. Who says medicine and military strategy are not connected? If generals are incompetent, soldiers are sent to their deaths; if physicians are incompetent, patients are used as test subjects for drugs. This is the subtle meaning behind Jingyue's use of "formation" to title his chapters.
This book was originally printed by Vice Governor Lu Qian'an during his tenure in Guangdong. It became highly sought after, with paper prices soaring in the five major capitals, making it difficult for seekers to obtain. Transport Commissioner Jia, who understood the principles of smoothness and reversal and mastered the logic of ascending and descending, harbored a sincere desire to benefit the world and thus re-engraved the woodblocks. In the first month of winter in the Gengyin year, I received the Emperor's mandate and departed immediately, unable to witness its completion. Two months later, Commissioner Jia showed me a letter stating that the reprinting of the *Jing Yue Quan Shu* (Complete Works of Zhang Jingyue) was finished and requested a preface. Although I am not talented, extending the intent of the late Wenzheng Gong regarding good physicians and good ministers, who knows that the past Mr. Zhang was not sufficient to be a good physician, and that the future Mr. Jia will not become a good minister to assist our August Sovereign in his boundless longevity? Therefore, I have written these few words to place at the beginning of the volume.
Written by Fan Shichong, Viceroy of Minzhe, from Shenyang.
