天 真 与 经 验

作者：梁遇春

天真和经验好象是水火不相容的东西。我们常以为只有什么经验也没有的小孩子才拥有天真，他那位饱历沧桑的爸爸是得到经验，而失掉天真了。可是，天真和经验实在并没有这样子不共戴天，它们俩倒经常是聚首一堂。英国最伟大的神秘诗人布莱来克著有《天真与经验之歌》。 在“天真之歌”里，他无忧无虑地信口唱出晶莹甜蜜的诗句，他简直是天真的化身，好象不晓得世上是有龌龊的事情的。然而在“经验之歌”里，他把人情事故用简单的辞句表现出来，真是找不出一个比他更世故的人了。他将伦敦城里扫烟囱小孩子的穷苦、娼妓的厄运说得辛酸凄迷，可说是看尽人间世的烦恼。可是他始终是那么天真，还常常亲眼看见天使。

也许有人会说，这班诗人们的天真是装出来的，最少总有点做作的痕迹，不能象小孩子的天真那么浑朴自然，毫无心机。但是，我觉得小孩子的天真是靠不住的，好象是很脆的东西，经不起现实的接触。并且当他们发现人情的险诈和世路的崎岖时，他们会非常震惊，因此神经过敏地以为世上除开计较得失利害外是没有别的东西，柔嫩的心或者就这么麻木下去，变成个所谓值得父兄赞美的少年老成的人了。他们从前的天真是出于无知，不值得去赞          美的，更值不得我们欣羡。

至于那班已坠世网的人们的天真就大不同了。 他们阅历尽人世间的纷扰，经过了许多得失哀乐，因为看穿了鸡虫得失的无谓，又知道在太阳底下是难逢笑口的，所以肯将一切利害的观念丢开，来任口说去，任性做去，任情去欣赏自然界的快乐。他们以为这样子痛快地活着才是值得的。他们把心机看做是无谓的虚耗，自然而然会走到忘我的境界了。他们的天真可说是被经验锻炼过了，仿佛在八卦炉里蹲过，炼成了火眼金睛的孙悟空。人世的波涛再也不能将他们的天真卷去，他们真是“世路如今已惯，此心到处悠然”，这种悠然的心境既然成为习惯，习惯又成天然，所以他们的天真也是浑然一气，没有刀笔的痕迹的。这个建在理智上面的天真绝非无知的天真所可比拟的，从无知的天真走到这个超然物外的天真，这就全靠着个人的生活艺术了。

小题1:概括地说，作者所欣赏的是怎样的天真？

小题2:在现实面前，小孩子的天真和已坠世网的人们的天真，有何不同表现？（各用一句话概括）
