It is suggested that before his interview with Ho Lu, Sun Tzu had only written the 13 chapters, but afterwards composed a sort of exegesis in the form of question and answer between himself and the King. Pi I-hsun, the author of the SUN TZU HSU LU, backs this up with a quotation from the WU YUEH CH`UN CH`IU: "The King of Wu summoned Sun Tzu, and asked him questions about the art of war. Each time he set forth a chapter of his work, the King could not find words enough to praise him." As he points out, if the whole work was expounded on the same scale as in the above-mentioned fragments, the total number of chapters could not fail to be considerable. Then the numerous other treatises attributed to Sun Tzu might be included. The fact that the HAN CHIHmentions no work of Sun Tzu except the 82 P`IEN, whereas the Sui and T`ang bibliographies give the titles of others in addition to the "13 chapters," is good proof, Pi I-hsun thinks, that all of these were contained in the 82 P`IEN. Without pinning our faith to the accuracy of details supplied by the WU YUEH CH`UN CH`IU, or admitting the genuineness of any of the treatises cited by Pi I-hsun, we may see in this theory a probable solution of the mystery. Between Ssu-ma Ch`ien and Pan Ku there was plenty of time for a luxuriant crop of forgeries to have grown up under the magic name of Sun Tzu, and the 82 P`IEN may very well represent a collected edition of these lumped together with the original work. It is also possible, though less likely, that some of them existed in the time of the earlier historian and were purposely ignored by him. [16]
Tu Mu's conjecture seems to be based on a passage which states: "Wei Wu Ti strung together Sun Wu's Art of War," which in turn may have resulted from a misunderstanding of the final words of Ts`ao King's preface. This, as Sun Hsing-yen points out, is only a modest way of saying that he made an explanatory paraphrase, or in other words, wrote a commentary on it. On the whole, this theory has met with very little acceptance. Thus, the SSU K`U CH`UAN SHU says: "The mention of the 13 chapters in the SHIH CHI shows that they were in existence before the HANCHIH, and that latter accretions are not to be considered part of the original work. Tu Mu's assertion can certainly not be taken as proof."There is every reason to suppose, then, that the 13 chapters existed in the time of Ssu-ma Ch`ien practically as we have them now. That the work was then well known he tells us in so many words. "Sun Tzu's 13 Chapters and Wu Ch`i's Art of War are the two books that people commonly refer to on the subject of military matters. Both of them are widely distributed, so I will not discuss them here." But as we go further back, serious difficulties begin to arise. The salient fact which has to be faced is that the TSO CHUAN, the greatest contemporary record, makes no mention whatsoever of Sun Wu, either as a general or as a writer. It is natural, in view of this awkward circumstance, that many scholars should not only cast doubt on the story of Sun Wu as given in the SHIH CHI, but even show themselves frankly skeptical as to the existence of the man at all. The most powerful presentment of this side of the case is to be found in the following disposition by Yeh Shui-hsin: [17] --It is stated in Ssu-ma Ch`ien's history that Sun Wu was a native of the Ch`i State, and employed by Wu; and that in the reign of Ho Lu he crushed Ch`u, entered Ying, and was a great general. But in Tso's Commentary no Sun Wu appears at all. It is true that Tso's Commentary need not contain absolutely everything that other histories contain. But Tso has not omitted to mention vulgar plebeians and hireling ruffians such as Ying K`ao-shu, [18] Ts`ao Kuei, [19], Chu Chih-wu and Chuan She-chu [20]. In the case of Sun Wu, whose fame and achievements were so brilliant, the omission is much more glaring. Again, details are given, in their due order, about his contemporaries Wu Yuan and the Minister P`ei. [21]
Is it credible that Sun Wu alone should have been passed over?
In point of literary style, Sun Tzu's work belongs to the same school as KUAN TZU, [22] LIU T`AO, [23] and the YUEHYU [24] and may have been the production of some private scholar living towards the end of the "Spring and Autumn" or the beginning of the "Warring States" period. [25] The story that his precepts were actually applied by the Wu State, is merely the outcome of big talk on the part of his followers.
From the flourishing period of the Chou dynasty [26]
down to the time of the "Spring and Autumn," all military commanders were statesmen as well, and the class of professional generals, for conducting external campaigns, did not then exist. It was not until the period of the "Six States" [27] that this custom changed. Now although Wu was an uncivilized State, it is conceivable that Tso should have left unrecorded the fact that Sun Wu was a great general and yet held no civil office? What we are told, therefore, about Jang-chu [28] and Sun Wu, is not authentic matter, but the reckless fabrication of theorizing pundits. The story of Ho Lu's experiment on the women, in particular, is utterly preposterous and incredible.
Yeh Shui-hsin represents Ssu-ma Ch`ien as having said that Sun Wu crushed Ch`u and entered Ying. This is not quite correct.
No doubt the impression left on the reader's mind is that he at least shared in these exploits. The fact may or may not be significant; but it is nowhere explicitly stated in the SHIH CHIeither that Sun Tzu was general on the occasion of the taking of Ying, or that he even went there at all. Moreover, as we know that Wu Yuan and Po P`ei both took part in the expedition, and also that its success was largely due to the dash and enterprise of Fu Kai, Ho Lu's younger brother, it is not easy to see how yet another general could have played a very prominent part in the same campaign.
