Shen was known for his cryptic writing style. Because the writings attributed to him appear to be pre-Han dynasty, he is credited with writing a now extinct two chapter text, the ''Shenzi'' (), which is concerned almost exclusively with the philosophy of governmental administration.

says that when Shen Buhai lived, the officials of the state of Han were at cross-purposes and did not know what practices to follow. Though not unifying the laws as

did, what Shen appears to have realized is that the "methods for the control of a bureaucracy" could not be mixed with the survivals of feudal government, or staffed merely by "getting together a group of 'good men'", but rather must be men qualified in their jobs. Unlike Shang Yang, Shen therefore emphasizes the importance of selecting able officials as much as Confucius did, but insists on "constant vigilance over their performance", never mentioning virtue. In comparison with

on the other hand his system required a strong ruler at the center, emphasizing that he trust no one minister. Ideally, Shen Buhai's ruler had the widest possible sovereignty, was intelligent (if not a sage), had to make all crucial decisions himself, and had unlimited control of the bureaucracy - over which, in contrast to Shang Yang, he is simply the head. Championing ''Fa'' (法 "method"), Shen believed that the greatest threat to a ruler's power came from within, and unlike Han Fei, never preaches to his ministers about duty or loyalty. He insisted that the ruler must be fully informed on the state of his realm, but couldn't afford to get caught up in details and was advised to listen to no one - and does not, as

says, have the time to do so. The way to see and hear independently is by grouping particulars into categories through mechanical or operational decision making (Fa or "method"). Shen's doctrines, posthumously referred to by Han Fei as Shu or Techniques (a term Shen does not appear to have used), are described as concerned almost exclusively with the "ruler's role and the methods by which he may control a bureaucracy", that is, its management and personnel control: the selection of capable ministers, their performance, the monopolization of power, and the control of and power relations between ruler and minister which he characterized as

. They can therefore easily be considered the most crucial element in controlling a bureaucracy. More specifically, Shen Buhai's methods (Fa) focused on "scrutinizing achievement and on that ground alone to give rewards, and to bestow office solely on the basis of ability". Liu Xiang wrote that Shen Buhai advised the ruler of men use technique (shu) rather than punishment, relying on persuasion to supervise and hold responsible, though very strictly. Liu considered Shen's "principal tenet" to be (''Xing-Ming'' 刑名).Creel 1970 p.62. What Is Taoism? https://books.google.com/books?id=5p6EBnx4_W0C&pg=PA62 Representing equally applied checks against the power of officials, Xing-Ming seeks the right person for the job through the examination of skill, achievement and (more rarely) seniority.

Rather than having to look for "good" men, Xing-Ming (or ming-shih) can seek the right man for a particular post, though doing so implies a total organizational knowledge of the regime. More simply though, it can allow ministers to come forward with proposals of specific cost and time frame, leaving their definition to competing ministers—the doctrine favored by Han Fei. Preferring exactness, it combats the tendency to promise too much; the correct articulation of Ming is considered crucial to the realization of projects.John Makeham 1994 p.67.

Shen supported reward for visible results, using ming-shih for investigation and appointment, but the legal system of Han was apparently confused, prohibiting uniform reward and punishment. We have no basis to suppose that Shen advocated the doctrine of rewards and punishment (of

. This "conception of the ruler's role as a supreme arbiter, who keeps the essential power firmly in his grasp" while leaving details to ministers, has a "deep influence on the theory and practice of Chinese monarchy." Shen Buhai argued that if the government were organized and supervised relying on proper method (Fa), the ruler need do little—and must do little. Unlike " Legalists"

and Han Fei, Shen did not consider the relationship between ruler and minister antagonistic necessarily. Apparently paraphrasing the

, Shen Buhai's statement that those near him will feel affection, while the far will yearn for him, stands in contrast to Han Fei, who considered the relationship between the ruler and ministers irreconcilable.Pines, Yuri, "Legalism in Chinese Philosophy", The Stanford Encyclopedia of Philosophy (Winter 2014 Edition), Edward N. Zalta (ed.), http://plato.stanford.edu/archives/win2014/entries/chinese-legalism/ However, Shen still believed that the ruler's most able ministers are his greatest danger, and is convinced that it is impossible to make them loyal without techniques.

explains: "The ruler's subjects are so numerous, and so on alert to discover his weaknesses and get the better of him, that it is hopeless for him alone as one man to try to learn their characteristics and control them by his knowledge... the ruler must refrain from taking the initiative, and from making himself conspicuous--and therefore vulnerable--by taking any overt action." Emphasizing the use of administrative methods (Fa) in secrecy, Shen Buhai portrays the ruler as putting up a front to hide his weaknesses and dependence on his advisers. Shen therefore advises the ruler to keep his own counsel, hide his motivations, and conceal his tracks in inaction, availing himself of an appearance of stupidity and insufficiency. Shen says: Acting through administrative method (Fa), the ruler conceals his intentions, likes and dislikes, skills and opinions. Not acting himself, he can avoid being manipulated. The ruler plays no active role in governmental functions. He should not use his talent even if he has it. Not using his own skills, he is better able to secure the services of capable functionaries. Creel argues that not getting involved in details allowed Shen's ruler to "truly rule", because it leaves him free to supervise the government without interfering, maintaining his perspective. Seeing and hearing independently, the ruler is able to make decisions independently, and is, Shen says, able to rule the world thereby. This Wu wei (or nonaction) might be said to end up the political theory of the "Legalists", if not becoming their general term for political strategy, playing a "crucial role in the promotion of the autocratic tradition of the Chinese polity." The (qualified) non-action of the ruler ensures his power and the stability of the polity.

Yin (passive mindfulness)

Adherence to the use of technique in governing requires the ruler not engage in any interference or subjective consideration.Makeham, J. (1990) pp. 90-91.

explains: "assessing words and deeds requires the ruler's dispassionate attention; (yin is) the skill or technique of making one's mind a tabula rasa, non-committaly taking note of all the details of a man's claims and then objectively comparing his achievements of the original claims." A commentary to the Shiji cites a now-lost book as quoting Shen Buhai saying: "By employing (yin), 'passive mindfulness', in overseeing and keeping account of his vassals, accountability is deeply engraved." The Guanzi similarly says: "Yin is the way of non-action. Yin is neither to add to nor to detract from anything. To give something a name strictly on the basis of its form – this is the Method of yin." Yin also aimed at concealing the ruler's intentions, likes and opinions.
