文学在漫长的历史过程中,形成了各种样式和体裁。这绝非偶然,而是客观规律使然。因而,任何一种样式和体裁,必然各有它独具的表现手段,也必然有它的弱点。十八般武器,各有各的长处,不能设想以大刀(或长矛或其他某一种)代替其余十七种。宋代李清照论词,“历评诸公歌词,皆摘其短,无一免者。”其论失之偏颇苛求,不足为训。但其“乃知词别是一家”的观点,实在是可取的。古人讲究诗语不入词,词语不入曲;甚至同样是诗,律诗与古诗的造句要有区别。诗词之间尚且如此,何况大类别之间! Literature in the long history of the process, formed a variety of styles and genres. This is by no means accidental, but an objective law. Therefore, any kind of style and genre necessarily has its own unique means of expression, but also inevitably has its weaknesses. Eighteen weapons, each having its own strengths, can not be imagined to replace the remaining seventeen with a sword (or spear or any other one).

The ancients pay attention to the poetic words, words into the song; even the same poetry, verse and ancient poetry to make a difference. So between poetry, not to mention large categories!
