“庸医司性命,俗子议文章”。这两件事,大概在800年前的陆游看来,是最煞风景的荒唐之举。其实,俗子议文章固不可,俗子议历史,则更遗害无穷,非把那本来就不清澈的历史长河搅得更浑更脏不可。鲁迅说:“因为历史结账,不能像数字一般精密,写下许多小数,却只能学粗人算账的四舍五入法门,记下一笔整数。”这就给一些不负责任的人在历史某些枝节上的胡言乱语、胡编乱造以可趁之机。 “Yong doctor’s life, vulgar proposition article.” These two things, probably about 800 years ago, Lu You, is the most ridiculous move of the landscape. As a matter of fact, the vulgar language of the article is irreconcilable, and the vulgar language of the history is even more endangered, not the muddleheadedness of the long history that was not clear. Lu Xun said: “Because the history checkout, can not be as precise as the number, wrote many decimals, but can only learn rough rounding method, write down an integer.” This gives some irresponsible people in the history of some Stubborn section of the nonsense, make up the chaos to take advantage of the machine.
