　　古大将之才，类出天授。然其临敌制胜也，要皆先识兵势虚实，而以避实击虚为百战百胜之法。文士家作文，亦何独不然？盖意乘间则巧，笔翻空则奇，局逆振则险，词旁搜曲引则畅。虽古今名作如林，亦断无攻坚摭实硬铺直写而其文得佳者。故一题到手，必静相其神理所起止。由实字勘到虚字，更由有字句处勘到无字句处。既入其中，复周索之上下四旁焉，而题无余蕴矣。及其取于心而注于手也，务于他人所数十百言未尽者，予以数言了之，及其幅穷墨止，反觉有数十百言在其笔下。又于他人数言可了者，予更以数十百言，排荡摇曳而出之，及其幅穷墨止，反觉纸上不多一字。如是又何虑文之不理明辞达、神完气足也哉！此则所谓避实击虚之法也。大 * * 得之以用兵，文人得之以作文，纵横天下，有余力矣。
