Because of the lack of archaeological evidence, there is no consensus among modern scholars concerning the date that The
Wuzi was composed, and/or last modified. A work known as
Wuzi was one of the most widely referenced books on military strategy among the records that existed in the
Warring States period. (Notable contemporary records mentioning the
Wuzi are the
Spring and Autumn Annals and the
Han Feizi.)
Sima Qian, in his
Shiji, equates the popularity of the
Wuzi, in both the
Warring States and the
Han dynasty, with that of
Sun Tzu's Art of War. There is evidence that, in the
Warring States, two different texts titled "
Wuzi" existed, but (at least) one of them has been lost. The fact that large portions of the text seem to have been either lost or deliberately excised from surviving editions makes the dating of the work more challenging. There is evidence both supporting the theory that much of the present text was authored in the mid-
Warring States, and that it was modified after this date. The most systematic study of the ''Wuzi's'' date of composition and authorship, based on historical references and the book's content, concludes that the core of the work was likely authored by Wu Qi himself, but was likely subject to serious losses of content, revisions, and accretions after his lifetime. This theory assumes that Wu Qi's disciples initially continued amending the text, but cannot account for some content that seems to have been inserted as late as the Han dynasty (possibly in an effort to "update" the work). The following five points summarize this study's conclusions regarding the
Wuzi's date of composition.
Historical references The writings of Wu Qi were known to be in wide circulation by the late
Warring States period. The assertion of the book's early popularity is based on the comment, from the
Han Feizi, that "Within the borders everyone speaks about warfare, and everywhere households secretly store away the books of Sun and Wu." The
Shiji corroborates this information. The
Wuzi continued to be studied both by famous
Han dynasty figures, and by those in the
Three Kingdoms period. The record of continuous attention supports the view that was continuously transmitted from the
Warring States until at least the
Three Kingdoms period.
Shared passages between contemporary works The
Wuzi shares both concepts and whole passages with other works dated more conclusively to the
Warring States period. (The texts with which the
Wuzi shares the greatest resemblance are the
Wei Liaozi,
Sun Bin's Art of War, and the
Six Secret Teachings.) The close similarities that the
Wuzi shares with other works from the
Warring States period suggest that the
Wuzi predates these other works, largely because
Sun Bin's Art of War had been lost for two thousand years, so passages from
Sun Bin's work could not have been lifted to forge the
Wuzi (just prior to the
Tang dynasty, as was claimed in later Chinese history.)
Perspective / occupation of writer Wu Qi was both a civil and military leader, and excelled in both occupations. This dual role was common until the early
Warring States period, but disappeared in later Chinese history. The fact that the
Wuzi was written from the perspective of an official with both civil and martial responsibilities supports the theory that it dates from the early
Warring States.
Archaeological support Qing scholastic criticism discounted the possible authenticity of the text based on its mention of military practices then considered anachronous to the
Warring States period. The list of items (then) considered anachronous includes: playing pipes in camp; the inclusion of terms not otherwise known to have been invented until after the
Warring States; and, the appearance of certain astrological banners used by different units. Because recent archeological discoveries have confirmed that all of these "anachronous" practices existed by the
Warring States, this Qing-era evidence for the
Wuzi's forgery is not valid.
Remaining criticisms Remaining criticisms which the defenders of the
Wuzi's authenticity cannot account for center on the book's description of cavalry as a major, important branch of the military. Because the use of cavalry (presumably) did not become important until the (very) late-
Warring States period, the text's emphasis on cavalry implies that present editions must have been edited after Wu Qi's death (unless cavalry became important in central China much earlier than presently believed). Unless evidence is found that cavalry became important in China before c. 300 BC (the date modern scholars generally assume Cavalry became important), then either parts of the
Wuzi, or the entire text, must be attributed either to the late
Warring States or the early
Han dynasty. Modern scholars conclude that the most satisfying conclusion, accounting for the above facts, is that the text was substantially created by "
Wu Qi himself, but that in the course of transmission and revision, later Warring States strategists (and probably Han students)... added passages on cavalry and otherwise emended some of the terminology." By being a work which was the product of a famous historical figure, but amended by future generations of strategists, the
Wuzi's composition is very similar to most of the other
Seven Military Classics. ==See also==
