昨夜于梦中得古诗数句，今朝推敲增删，恰凑得成八韵五古一首。

 

 

春寒梦呓　－　梦成五古八韵注

春寒万籁轻， 月华漫窗棂。 梦浅乡愁近， 顿怜父母情。 十载决然去， 苍鸟飞不停。 书生百无用， 枯坐老一经。 乏力从定远， 报国岂无凭？ 封侯尘土没， 格物释儒倾。 燕雀迷堂构， 鲲鹏探杳冥。 会当答天问， 斗酒祭屈平。

http://www.wanyidun.com/blog_r2u/?p=595 皆谓今人之填词作诗宜多用典，典用则古意盎然，格调高致。余以为不然。非谓典不可用，实须适度为之，若处处寻章摘句，假古人言，则艺文一道何以进步，何以 发展？子云：“《诗》三百，一言以蔽之：思无邪。” 何以思无邪？盖直、真、挚三字而已，岂有他哉？  ”蒹葭苍苍，白露为霜。所谓伊人，在水一方……“ 何其直白，真挚也？若言《诗》乃后世诗词之祖，无典可用，则唐人诗作中可谓 “千古绝句” 者，亦多为不用典者。  “花间一壶酒，独酌无相亲。举杯邀明月，对影成三人……” 何典之有？  “空山新雨后，天气晚来秋。明月松间照，清泉石上流……” 何其直也？ “无边落木萧萧下，不尽长江滚滚来……” 又何典之有欤？仅此一句便可关千古登临之口，几与 “西风残照，汉家陵阙。 “同。“平林漠漠烟如织，寒山一带伤心碧……” 词尝疑为太白所作，非也，实乃宋人托古之计也，然世人信焉。何也？ 盖诗句直白若此又意境高绝者，太白之外实难做第二人想也。又，“长江悲已滞，万里念将归。况属高风晚，山山黄叶飞。” 句，思归之情，跃然纸上，登临之境， 亦不下太白之箫声咽词（注）。

　　语既及王勃，当不可不谈其脍炙人口之《滕王阁序》。《序》可居历代骈文之首，殊无异议，其用典之多，之 精，辞藻之华丽，千载以降，无出其右者；少年意气，英姿勃发，亦鲜有比肩者。将可藉此而鼓吹多用典乎？余谓不可。《序》之如此，其时、其势使然。时骈四俪 六之风盛行，自不必言。其势者，王勃虽少年英才，却也”三尺微命，一介书生“，既是“躬逢盛饯”，敢不为华章以悦宾主乎？况其年少气盛，又才冠当世，能不 旁征博引以惊四座，或有伯乐隐于席间亦未可知？想《序》之洋洋万言、引经据典，吾等好诗文者以为范本，于平日练习时临摹仿效，自是裨益良多，亦可尝以 “无 路请缨，等中军之弱冠；有怀投笔，爱宗悫之长风。” 自励，然若言其中最为千古传颂者何，“落霞与孤鹜齐飞，秋水共长天一色。” 此十四字为当然尔，果不其然乎？后人若以《序》为榜样，以为非这般如此不能为好诗文，然无王勃用典之才而强为者，岂非东施效颦耶？

　　用典有好用替代字者，辟如，言 月不及月，而以飞镜、沉璧、桂华等代之，写桃不语桃，却来红雨，刘郎等代之。观堂有谓：词忌用替代字，其所以然者，非意不足，则语不妙也；意足则不暇代， 语妙则不必带。余深以为然。如非词难达意，造句难至妙境，何必借他人之笔墨欤？无论写景写情，须使人读之若历历在目，感同身受；以童叟皆识之字，造雄苍阔 远之境，抒嵯峨萧瑟之意，言真意切，余味绵绵，令人欲罢不能。反之，纵使句句惊才绝艳，却晦涩不明，读之亦犹如水中观月，美则美矣，却终不可及，恨也！何 不能如温子昇之 “素蝶向林飞， 红花逐风散。 花蝶俱不息， 红素还相乱” ？ 诗人喜用替代字似自宋始，诗词一道亦随之式微，其后虽偶有佳作天成，亦难阻颓势，及至今日，殆矣。而今人欲以用典、托古为作诗填词之大道，反致成句满篇， 几如舍本逐末，何其谬也哉？ 殊不知，今人写景，若得似“大漠孤烟直，长河落日圆。”，写情，若得似“晚来天欲雪，能饮一杯无？”，便真具古风三昧也。

　 　及于此，皆谓诗词之至境所言。然后学末进如我，一味追逐至境，不免画虎不成反类犬，终落末乘。若非天造之诗才，不妨多读书，多读诗，适度用典，成句亦 可，倘心中恒存至境，当为学诗之不二法门也。古有诗云：”谁能思不歌，谁能饥不食？“因思而歌则直、真、挚必达。倘使今人复此境界，则诗道之复兴亦不远 矣。

注：亦指疑为李白所作之《忆秦娥 • 箫声咽》词 “西风残照，汉家陵阙“ 句。
