能跑的才叫车,能实践的才叫思想

Filed under: 言论 — gcd0318 @ 02:34

中国的传统学问一向重视实践,所谓的“直指世道人心”,所有的思想都要有用。这种风气不只存在于哲学和思想领域,还影响到了几乎所有的学科,比如研究诗是为了写诗,研究数学是为了分田,总之只研究有用的,数学里的几何和数值计算最能直接应用,所以中国的这两方面就非常发达,而且保留下来的数学书也几乎都是应用题和解决步骤,描述一个实际的场景,然后按照几步走下去,就一定可以得到答案——吴文俊教授说中国古代的数学就是算法,是计算机的数学,道理也就在此——至于为什么可以这样做,怎么保证得到的就是答案,以及对应用的抽象,则几乎没有讨论,因为这些东西都“没用”,所以不去研究
有人说中国这种“没用的就不研究”的态度很不好,导致中国一直都只有技术而没有科学,尤其没有纯科学,艺术理论也不纯粹,思想也难以进化提升到哲学的高度,只能是朴素的,零碎的。不过我倒是觉得这才是中国传统学术的优越性得以体现的地方:能实践,才能知道好歹,才能比较优劣,就好像斫轮解牛,只要让轮子转起来,把牛肉切出来,一看就知高下。而不能实践的思想,弊病也就在此,就像两套屠龙之技无法比较一样,不能用实践来验证
倘若不能实践,那么大家就只好在理论上去谈。但是无论怎么谈,最终也都是纸上谈兵,说不清楚。既然说不清楚,那就可以继续去说,永远说不清楚,因此永远的说——看看如今西式体制下的这些学院里的专家教授学者们,很多人就是靠发论文来提职称赚稿费养家糊口,顺便尽情挥洒着它们那本来也毫无用处的青春——这也算是“无用之用方为大用”了
当然了,还有些人对这种“一切都要实践”的观点有看法,是因为它们认为这种观点把“思想”给庸俗化了,不纯粹,认为思想不是为了用,思想本身就是目的
这种人当然没有前面那些人那么阴暗,但是也好不到哪去,甚至还可能更糟糕。这种对实践的不参与,其实恰好可以给别有用心者留下生存的空间。这些人也许有真懂行的人,但是却不去做实践,于是就导致了“真佛不下凡,人间处处野狐禅”的可怕局面,让谬种流传,劣币逐良币,搞的人间只认假货不认真货了。于是,真正懂昆曲的人不包装,反倒成全了白先勇,真正懂中医的人不坐堂,反倒成全了张悟本,真正懂艺术的人不创作,反倒成全了798。就如我在老帖里多次强调过的,不能因为没有真货就容忍冒牌,不能因为没有米面就开水煮石头,不能因为缺爹少妈就看谁都叫爸爸,不能因为没有秧苗就让地上长草,空地上播种就可以耕耘收获,要是长满了杂草,那就消耗了土地的养分,再要播种的时候还要多一道除草的手续——我估计许悦看到这个说法,又要和我掰扯了,嘿嘿
其实还要说明的一点就是,我并不反对搞理论,闭门造车不是问题,问题在于,造车的人即使闭门,也要脑子里有路,要明白车最终还是要在路上跑的,倘若是忘记了这个,那就是在瞎折腾了

  1. 以前研究数论的人,心里想的可能就是纯粹的数字,也一直觉得在现实中毫无用处;谁知道现在会有用了呢。况且即便永远没有用,数论本身的价值还是在那里的。

  2. 也就是说,最终数论还是有了用处,没错吧?包括线形代数,黎曼几何,当初都是为了好玩才弄出来,但是最终,都还是有用的

  21. I’ve created inside of a previous put up which you cannot expect the typical voter to browse the WSJ editorial webpage, Nationwide Review, Commentary as well as the academic papers of the University of Chicago’s economics department. Simply because they do not, and therefore may well not be influenced by conservative/libertarian ideas, does not necessarily mean the public is silly. I’m a cynical, critical guy, but when it will come towards the public’s decisions-disagree with them as I do-I give them a pass. To believe that the public is stupid will be to drop in the trap of pandering and avoiding discussing the truth in direct, hard-hitting formulations. In other terms, doing exactly what the Republicans did inside their conference and exactly how Romney is working his campaign.

  27. I needed to draft you that little observation so as to thank you so much once again considering the stunning basics you’ve shown here. It is so unbelievably open-handed with you to grant publicly precisely what a few people would’ve marketed for an e-book to end up making some bucks on their own, even more so given that you might well have tried it in case you wanted. Those techniques likewise acted like the easy way to fully grasp the rest have the identical dreams much like mine to know very much more regarding this issue. I think there are a lot more enjoyable instances up front for individuals that see your blog post.
