pronounces the style of the 13 chapters to belong to the early
part of the fifth century. Seeing that he is actually engaged in
an attempt to disprove the existence of Sun Wu himself, we may be
sure that he would not have hesitated to assign the work to a
later date had he not honestly believed the contrary. And it is
precisely on such a point that the judgment of an educated
Chinaman will carry most weight. Other internal evidence is not
far to seek. Thus in XIII. ss. 1, there is an unmistakable
allusion to the ancient system of land-tenure which had already
passed away by the time of Mencius, who was anxious to see it
revived in a modified form. [30] The only warfare Sun Tzu knows
is that carried on between the various feudal princes, in which
armored chariots play a large part. Their use seems to have
entirely died out before the end of the Chou dynasty. He speaks
as a man of Wu, a state which ceased to exist as early as 473
B.C. On this I shall touch presently.

But once refer the work to the 5th century or earlier, and
the chances of its being other than a bona fide production are
sensibly diminished. The great age of forgeries did not come
until long after. That it should have been forged in the period
immediately following 473 is particularly unlikely, for no one,
as a rule, hastens to identify himself with a lost cause. As for
Yeh Shui-hsin's theory, that the author was a literary recluse,
that seems to me quite untenable. If one thing is more apparent
than another after reading the maxims of Sun Tzu, it is that
their essence has been distilled from a large store of personal
observation and experience. They reflect the mind not only of a
born strategist, gifted with a rare faculty of generalization,
but also of a practical soldier closely acquainted with the
