The Renwuzhi 人物志 "About human character" is China's oldest book on psychology. It was written by the Three Kingdoms period 三國 (220-280) scholar Liu Shao 劉卲 (182-245 CE). Liu Shao, courtesy name Liu Kongcai 劉孔才, came from Handan 邯鄲 (modern Handan, Hebei) and was a retainer of the Heir Apparent during the Jian'an reign 建安 (196-219). In the early Huangchu reign 黃初 (220-226) he was promoted to gentleman in the Department of State Affairs (shangshu lang 尚書郎), gentleman cavalier attendant (sanji shilang 散騎侍郎), and then. Under the reign of Emperor Ming 魏明帝 (r. 226－239 CE) of the Wei dynasty 曹魏 (220-265) he was appointed governor (taishou 太守) of Chenliu 陳留. Called back into the central government he was made commandant of cavalry (jiduwei 騎都尉) and then rose to the post of cavalier attendant-in-ordinary (sanji changshi 散騎常侍). As a highly educated person he was granted the title of Marquis within the Pass (guanneihou 關內侯) during the Zhengshi reign 正始 (240-248). Liu Shao has written several rhapsodies, namely Zhaodu fu 趙都賦, Xudu fu 許都賦, and Luodu fu 洛都賦, in which he reveils a very critical stance towards the society of his times. Of his other books Huanglan 皇覽, Duguan kaoke 都官考課, Lülüelun 律略論 and Falun 法論, only fragments have survived. Only the treatise Renwuzhi is transmitted in full.
The book is 3 juan "scrolls" long and divided into 12 chapters. During the Tang 唐 (618-907)
and Song periods 宋 (960-1279) it was rated as a treatise of the "school of dialecticians" (mingjia 名家), but the compilers of the imperial collectaneum Siku quanshu 四庫全書 from the Qing period 清 (1644-1911) categorized it as a "miscellaneous" treatise.
Human nature is expressed, according to Liu Shao, in two different ways, namely talent and character. These can be rightly applied for specific use after careful analyis. Talent (cai 材 "matter") can be acquired by learning, yet all humans have also a certain portion of natural talent that is different is each person. Some persons have more of it, others less, some develop it earlier, others later. Human talents can be used for different purposes, and not everyone is able to take over each task. Sparingness, artificial skills, judicial skills, politics, the arts, philosophical talents, literary abilities, rhetorics or a heroic spirit are such talents that are unequally distributed among all people. Character is influenced not only by Yin and Yang 陰陽 and the Five Processes 五行 of which the cosm is composed and to which it is subject, but also by the physical conditions of the body that are related to the Five Processes (wood to the bones, metal to the muscles, fire to the breath, earth to the skin, and water to the blood). There are, accordingly, strong people or weaker ones, audacious or prudent persons, persons with a love for specialized details and others with a broad interest, persons that are lenient and such that are impatient, active and moving people or passive and quiet persons, and people that like opennes and other loving to conceal matters. Similarly, the five constant virtues (wuchang 五常) kindheartedness (ren 仁), righteousness (yi 義), propriety (li 禮), trustworthiness (xin 信) and wisdom (zhi 智) are influenced by nature. These can be perceived in the general appearance, conduct, voice and facial complexion. These natural dispositions of character and talent are one-sidedly inclined (pianzhi zhi xing 偏至之性, pianzhi zhi cai 偏至之材) and cannot be altered. The morally highest character is that of a "central harmony" (zhonghe 中和), in which Yin and Yang are pure and harmonic and the five learnable talents do not need to be adjusted.
Through a careful investigation of human talent and character a ruler will be able to give everyone an appropriate position in the state administration and, in a wider sense, also in society. This is, according to Liu Shao, possible because talent and character can be perceived by certain factors (the jiuzheng 九證 "nine proves") that appear at the surface, namely spirit, wit, the physical condition, breath, colour of the face, comportment, general appearance, and speech. Yet the author also discusses reasons for an eventual failure of such an analyis and the reasons why talent and character are not necessarily apparent from the physical appearance. These are the seven resemblances (qisi 七似) and the seven errors (qimiu 七謬). The methods for analyis are the eight observations (baguan 八觀) and five inspections (wushi 五視).
The method of rating persons and attributing a certain categorical rank to them followed the method during that time to give all important families a certain rank that qualified them for according positions in the state administration. The Confucian concept of the holy man (shengren 聖人), the perfect noble, is explained by the terms youming 有名 "able to become famous" and wuming 無名 "not able to make oneself a name", terms going back to Daoist thought of the activation of the "not" that corresponds to the natural way, the Dao, but also to the idea of a destiny posed upon the life of everyone.
There is a commentary written by Liu Bing 劉昞 (also written 劉昺) during the Northern Wei period 北魏 (386-534). The Renwuzhi was printed during the Song period 宋 (960-1279) by Ruan Yi 阮逸. For a long time it was categorized as a text of the schools of dialecticians (mingjia 名家), and Ruan Yi was the first to see it as a historiographical book. The compilers of the collectaneum Siku quanshu 四庫全書 categorized it as a "miscellaneous treatise". The most common edition is a Ming period 明 (1368-1644) print included in the collectaneum Sibu congkan 四部叢刊.
