It's in the silences,
The words you never say
I see it in your eyes,
Always starts the same way.
It seems like everyone we know,
Is breaking up
Does anybody ever stay in love, anymore?

(chorus)
I promise you,
From the bottom of my heart
I will love you till death do us part
I promise you as a lover and a friend
I will love you like I never love again
With everything I am

I see you look at me,
When you think I'm not aware
You're searching for clues,
Of just how deep my feelings are.
How do you prove the sky is blue, the ocean's wide?
All I know is what I feel,
When I look into your eyes.

(chorus)

There are no guarantees
That's what you always say to me
But late at night I feel the tremble in your touch
Oh what I'm trying to say to you,
I never said to anyone

(chorus)
(I do my darling I promise you)
(chorus)
(I love you I love you I love you I love you)
I promise you as a lover and a friend
I will love you like I never love again
With everything I am
You're everything I am oh yeah
with everything I am

这首歌高中时候听过，可是一直不知道其中某些语句的
意思，懒得翻译了，呵呵，只把不懂的部分写出来吧...

就是 with everything I am 似乎说不通，google 下没看
见比较官方的解释，暂时理解为 with everything I am to you。
然后 do us part 也很诡异，发现是不是歌词搞错了，也许是
till death do us apart，可是 death 为啥不是 does us apart
呢？但是其实搜到的还都是 death do us part... 诡异啊诡异

孤独，似乎是一个跨越时间和空间的人类共病。

波兰著名导演基耶斯洛夫斯基说，最初，他关注的是
公正和自由，认为这是波兰的首要问题，但他后来明
白，等波兰成为法国那样的国家后，有一个问题仍然
不可逾越，这个问题就是孤独。他发现，不管是欧洲
哪个国家或是美国，到处都弥散着难以穿越的孤独。

美国小说家卡罗琳·帕克丝特则在她的处女作《巴别塔
之犬》中写了一个令人唏嘘不已的故事：一个女人从
树上坠地死亡，她的语言学家丈夫不理解她为什么这
么做，而他们的狗是当时的唯一目击者，所以他想教
会狗说话，好让它告诉自己，当时到底发生了什么，
最后，他没有教会狗说话，但他从对妻子的回忆中发
现，其实妻子一直在对他诉说她的痛苦，而他却一直
忽视。

我最近的一系列文章也在写这样的困境：我们渴望爱，
可我们又都沉浸在自己的小我中，自恋地以为自己是
这个世界的中心，并试图将自己的小我强加到周围的
人身上，而一个人若对我们越重要，我们这种强加的
动力就越强，所以，对爱的渴望反而成了压制彼此的
精神生命。

听上去，这真是令人悲观，看来无论我们怎么努力，
都是碰触不到彼此，而只能陷在小我的幻觉世界中。

但其实，我们又生活在一个心灵感应时刻都在进行着
的世界，我们时时刻刻地在影响着彼此，只是我们意
识不到而已。

继续一篇

名声，或许是比金钱更诱人的东西，因名声不仅可以
间接带来物质利益，还可以带来影响力。

所谓影响力，即我可以将我的小我加诸于多少人之上。

小我，也即我们常说的自我，或心理学说的人格。小
我的核心是自恋，总在幻想自己是世界的中心，可以
左右周围的一切。

因而，影响力就是“小我”的一种根本性欲求了，越有
影响力，就越是证明了自己对周围世界的控制能力，
仿佛以此就可以证明，自己真的在左右着这个世界。

并且，名声是一种不加强迫的影响力。它与权力不同，
权力纵然可以赤裸裸地迫使别人被自己所左右，但别
人的不情愿势必会破坏“我左右着一切”的自恋幻觉。
相比之下，具有很大名声的人就可引诱别人按照自己
的意思去做事了，这种影响力更附和小我的幻觉。

所以，电视剧《乾隆皇帝》中，乾隆对不知道自己是
谁而仍然青睐自己的女子非常在乎，他觉得这是真正
证明了自己的魅力。

一个人青睐自己就这么得意，那些现代的万人迷甚至
亿人迷岂不是更加春风得意？

真正清醒的人应该不会这么看，因为名声本身就是一
个谜局。

关于惧怕的一篇。

孩子怕宠物，或许只是象征意义。

我那几位朋友和这个小女孩神情中有一个很相似的地
方，都是看上去非常依赖的那种。

并且，其中两位朋友和我深聊过，她们知道自己依赖
成性，对自己依赖这一点，她们既觉得这样不好，又
觉得只有这样才能赢得别人的爱，所以她们心情很是
矛盾，平时有点刻意不去看自己这一点。

但是，当毛茸茸的小型宠物突然出现在她们眼前时，
就好像心中那个“依赖的我”戏剧性地跳在她们面前，
迫使她们不得不去面对，她们对自己心中“依赖的我”
非常排斥，这一排斥投射到外部世界，就表现成她们
对仿佛是依赖象征的小型动物的恐惧。

人们对动物的恐惧五花八门，比较一致性的恐惧是恐
惧被袭击，而除此以外的恐惧，则常是被压抑的“我”
的投射，还常是象征性的。

小型宠物是无助、可爱的依赖的象征，对小型宠物的
恐惧则多是我们对自己依赖的一面的排斥的投射。

蜘蛛的网则是无所不在的控制的象征，而对蜘蛛的恐
惧，则常是我们对自己控制一面的排斥的投射。

我和几个有蜘蛛恐怖症的人聊过，最后发现无一例外，
他们真正恐惧的其实是自己的妈妈。他们的妈妈控制
欲望极强，和他们紧紧地黏在一起，生怕他们长大，
生怕他们独立而离开自己，于是用各种办法限制他们
独立，譬如不让他们和别人交往，不让他们去外地读
书，晚上也必须早早回家。但是，另一方面，这些妈
妈也是具有奉献精神的，她们会在物质和时间上牺牲
自己，而对孩子极好。

本来，我们的文化和家庭风格就不允许孩子质疑父母
对自己的爱，而假若父母看起来真的做出了巨大的牺
牲，那么孩子就更不能对父母进行质疑了，他们的父
母不允许，大家族不允许，社会不允许……最终，他
们自己也不允许自己质疑了。

但是，感受一旦产生就不会消失，控制欲望极强的妈
妈会给孩子带来很大的困扰，而他们对这样的妈妈也
会生出排斥心理，如果他们意识上不允许自己表达这
些困扰和对妈妈的负面情绪，那他们的潜意识中就会
埋藏着大量的这类信息，一旦找到一个突破口，便会
喷涌而出。

将控制欲望极强的妈妈比喻成蜘蛛，就是这时候的潜
意识玩的游戏。看起来是对蜘蛛充满恐惧，其实这只
是自己人生处境的一个象征罢了。

并且，如果有一个控制欲望极强的妈妈，那么一个人
的内心就势必会形成一个特定的内在关系模式——“左
右一切的内在的妈妈”和“被左右一切的内在的小孩”。

也就是说，尽管他们作为孩子会讨厌妈妈的控制，但
在其他人际关系中，他们却很容易以“左右一切的内在
的妈妈”自居，而将“被左右一切的内在的小孩”投射到
别人身上，并实施从妈妈那里学来的一切控制手法。
结果，不仅妈妈是只蜘蛛，他们自己也是一只蜘蛛。
他们假若意识上看不到妈妈是只蜘蛛的事实，也一样
会看不到自己是只蜘蛛的事实。

然而，一旦看到一只真正的蜘蛛的存在，这个被压抑
在潜意识中的真相就一下子会被触动，并以“蜘蛛恐
怖症”的形式表达了出来。

另外几句话： 心理学学到最后会失去同情心，便是因为这个道理。
因为同情心总是所谓的强者对弱者的奖励，但实施同
情的，真是强者吗？索取同情的，真是弱者吗？

或者，起码我们会看到，同情心会奖励弱者，而让弱
者一直以弱者自居。

譬如，如果一个心理医生能化解一个依赖成性的来访
者所有的疑问，那么，这个来访者就会对自己的依赖
逻辑——“我越无助别人会越爱我”——就会更执著，
他会认为他的人生答案就在于找到一个好的依赖对象，
而不是他自己。

但是，如果咨询室中出现沉默，这个投射与认同的游
戏就会被打断，当心理医生既不接话茬也不制造话茬
时，来访者投射的内容就会反转到自己身上，从而对
自己投射的内容有了一个觉知的机会。

所以，可以说，心理医生的沉默，反而在咨询室中营
造了一个空间，可以让来访者更好地觉知自己，而这
是最重要的，正如印度哲人克里希那穆提所说——
“唯一重要的是点亮你自己心中的光”。

我爱玩摄影，而资深的摄影爱好者知道，一张好照片
的一个特征便是有“空气感”，要拍出这样的照片，就
需要去注意取景范围中的空间，而不是将注意力全放
在实物上。

并且，想拍出任何一张好照片都需要先腾空自己的脑
袋，也即放下自己的思维，那样才能将注意力投诸在
被拍摄对象上，从而能用心碰触到被拍摄对象的迷人
之处。如果你将注意力放在自己的思维上，不管你怎
么玩，都很难拍出震撼人心的照片。

一张照片并非仅是对拍摄物的表现，一张照片表达的
是一种关系，是你的“真我”与被拍摄物的本真的关系。

一个有趣的现象是，喜欢使用评价的人喜欢确定感，
说起话来斩钉截铁，而富有创造力的人却势必能容忍
甚至喜欢模糊状态。

这是因为，评价源自“小我”，而“小我”无比自恋，真以
为自己知道一切左右一切，所以喜欢评价的人就喜欢
表现“小我”的自恋。相反，富有创造力的人不会急着去
解释，他们知道，所谓的模糊状态，也即自己的“真我”
还没有和事物的本真相遇。这时，假若急着去给予解
释，就是强行将“小我”强加给事物，于是就远离了事
物本质了。所以，容纳模糊状态，也就是他们的“真我”
和事物本真慢慢相遇的过程。

因为，在和苦难抗争的过程中，我们形成了对抗苦难的
武器。但是，如果没有苦难了，武器还有存在的必要吗？

试着去问自己这个问题，你会发现，你很容易会爱上
你发明的武器，你不愿意它被放下、封存甚至销毁，
你无意中渴望它一直发挥作用，这就意味着，它所针
对的痛苦应一直存在下去，否则它就没有存在的意义
了。

本来是用来消灭痛苦的，但最后却出现了相反的结果：
武器的存在需要以痛苦为食。

这种二元对立的现象无处不在。不管在什么地方，当
我们追求这一方向的事情时，相反方向的力量势必会
产生。

这很容易理解，正如一个天平，当我们在这边加砝码
时，那边也得加，否则天平就会失去平衡。

因而，当你追求卓越的程度是10分时，你惧怕失败的
程度也会是10分。

同样，当你追求善良的程度是10分时，你愤恨邪恶的
程度也会是10分。于是，一个绝对的理想主义者一旦
获得权力，他一定会是一个暴徒，因为他会严重排斥
不符合他理想的一切人，并最终对这些人动起杀机。

很遗憾不能回去当面祝福你们了
遥远的祝福你们~

Hinton 大牛看来和俺不是一个星球上的生物...
1 的 tutorial 里面说 SVM：
Vapnik and his co-workers developed a very clever type of perceptron,
called a Support Vector Machine...
最后表扬一番后
But it's just a perceptron and has all the same limitations.

另外对于自己的模型 deep belief nets 大加赞赏之余
也不忘调侃我辈的研究工作，有人可能问 Hinton 大
牛
How many layers should we use and how wide should they be?
大牛说，这和下面的问题等价
How many lines of code should an AI program use and how long should
each line be?
然后說 deep belief nets 给大家的是 freedom，
If freedom scares you, stick to convex optimization of shallow models
that are obviously inadequate for doing artificial intelligence.

orz to death... 是不是应该搞个 Hinton 大牛语录？

究竟有没有神？

如果认为存在神，人对它进行膜拜，领会神的教义，
向神倾诉自己的苦恼，希望得到神的指示，完成对自
身的救赎。但是一旦失败，往往会质疑神。但虔诚的
信徒质疑之后还是通过自己的办法获得解脱。

如果不认为存在神，那么就会认为，神是人所创造出
来的，因此没有必要依照神的旨意行事。所能依靠的
是自己，没有神的倾诉，心灵似乎得不到解脱，因此
完成这一功能的可能是家人是朋友。中国人多数不信
奉神，是不是也因此更加依赖于人与人互相的关系了
呢？

神可以感叹：你们这些人类啊，总是不顾自己有多大
的能力和体力，总是妄想逆天而行，甚至不满神赐给
的大地，把自己的魔掌伸向宇宙，到如今，甚至还敢
像这样和神战斗。你们人类应该对神无比的信仰，而
现在你们却忘记了这种虔诚的精神。与其说你们愚蠢，
不如说你们成了彻底悲哀的存在。

人会反驳，神应该是正义的。

可是对神而言并不存在正义，只存在天意。正义是人
的概念，渴望正义的人不能祈求神给予自己需要的理
想。

固执的神认为，自己高于人一等，人必然是愚蠢的，
因此为了施加自己的教化，强迫人类受苦。

人类说道：一生没有踩死一只昆虫，一生没有摘过一
束花朵，那样的人类不可能存在吧。人类终归不是神，
多么崇高的人类都会偶尔犯下过错，但是这就是生存。
认了终究会因为生存而犯下过错，但是死亡不正是对
这种过错的惩罚吗？无论善人还是恶人，都已各自不
同的死亡偿还了罪孽，他们死后不应享有永远平等的
安详吗？因生前的罪恶而遭受死后的惩罚，这恰恰是
神犯下的错。

人类拥有一个“爱”的东西，在神看来人类可能看来的
确无可救药，可是为了那份爱，人类可以变得无比善
良，也可以变得无比坚强，即便是神，如果不去理解
爱，就没有制裁人类的权利。这就是爱，是从生命的
源泉中涌出的爱的力量，这种力量不会输给任何东西。

哈迪斯告诫雅典娜说道：到最后，人类还是无法取得
完全的胜利，生为女神的你合适才会醒悟，“爱”这种
东西只不过是人类的幻想，是虚无的，看不见又摸不
到的爱，又怎么能够相信？没人会相信啊...

神因为永存而无法体会到人类因为生命的短暂而在生
存的过程中饱受的艰辛，因为人类并不是完全没有良
知，也并不是因为不想使得自己的道德高尚，而是因
为这就是生存。

为了逃避这种状态的生存，人类只能通过死亡。可是
为什么我们却要活着？因为那份看不见摸不着的爱，
因为生命本来就很短暂，也因为我们也仅有这一次的
生命。

这和神存在与否没有任何因果关系。

对 coding theory 熟一点的人都知道 Hamming，这是
他做的一个 talk，摘录一部分，供参考。

One of the characteristics you see, and many people have it
including great scientists, is that usually when they were
young they had independent thoughts and had the courage
to pursue them. For example, Einstein, somewhere around
12 or 14, asked himself the question, ``What would a light
wave look like if I went with the velocity of light to look at it?''
Now he knew that electromagnetic theory says you cannot
have a stationary local maximum. But if he moved along
with the velocity of light, he would see a local maximum.
He could see a contradiction at the age of 12, 14, or
somewhere around there, that everything was not right and
that the velocity of light had something peculiar. Is it luck
that he finally created special relativity? Early on, he had
laid down some of the pieces by thinking of the fragments.
Now that's the necessary but not sufficient condition. All
of these items I will talk about are both luck and not luck.
这部分讲述乐一些 independent thinking 的问题，即越早出现
independent thinking 越容易出结果，另外一点就是对于自己
的想法一定要执着。不要放弃或者忘记。

One of the characteristics of successful scientists is
having courage. Once you get your courage up and believe
that you can do important problems, then you can. If you think
you can't, almost surely you are not going to. Courage is one
of the things that Shannon had supremely. You have only to
think of his major theorem. He wants to create a method of
coding, but he doesn't know what to do so he makes a
random code. Then he is stuck. And then he asks the
impossible question, ``What would the average random code
do?'' He then proves that the average code is arbitrarily good,
and that therefore there must be at least one good code. Who
but a man of infinite courage could have dared to think those
thoughts? That is the characteristic of great scientists; they
have courage. They will go forward under incredible
circumstances; they think and continue to think.
勇气很重要，有时候有了勇气才会想另外的策略来解决目前
的问题。

When you are famous it is hard to work on small problems.
This is what did Shannon in. After information theory, what
do you do for an encore? The great scientists often make
this error. They fail to continue to plant the little acorns from
which the mighty oak trees grow. They try to get the big thing
right off. And that isn't the way things go. So that is another
reason why you find that when you get early recognition it
seems to sterilize you. In fact I will give you my favorite
quotation of many years. The Institute for Advanced Study in
Princeton, in my opinion, has ruined more good scientists
than any institution has created, judged by what they did
before they came and judged by what they did after. Not
that they weren't good afterwards, but they were superb
before they got there and were only good afterwards.
做问题一定要从小的开始，切勿一开始就找一个很大的问题，
Hamming 举的很多成名人士成名后很难做出与之能媲美的结
果的例子。即便我们研究生，做问题的时候也应该注意。

This brings up the subject, out of order perhaps, of working
conditions. What most people think are the best working
conditions, are not. Very clearly they are not because people
are often most productive when working conditions are bad.
One of the better times of the Cambridge Physical
Laboratories was when they had practically shacks - they did
some of the best physics ever.
逆境促人成长。

And there are many other stories of the same kind; Grace
Hopper has similar ones. I think that if you look carefully you
will see that often the great scientists, by turning the problem
around a bit, changed a defect to an asset. For example,
many scientists when they found they couldn't do a problem
finally began to study why not. They then turned it around the
other way and said, ``But of course, this is what it is'' and got
an important result. So ideal working conditions are very
strange. The ones you want aren't always the best ones for
you.
将 defect 变成 asset 的智慧，这是很重要的。

Now for the matter of drive. You observe that most great
scientists have tremendous drive. I worked for ten years
with John Tukey at Bell Labs. He had tremendous drive.
One day about three or four years after I joined, I
discovered that John Tukey was slightly younger than I
was. John was a genius and I clearly was not. Well I went
storming into Bode's office and said, ``How can anybody
my age know as much as John Tukey does?'' He leaned
back in his chair, put his hands behind his head, grinned
slightly, and said, ``You would be surprised Hamming,
how much you would know if you worked as hard as he
did that many years.'' I simply slunk out of the office!
勤奋努力，珍惜时间。为什么别人比自己知道的多，这
是原因啊，可能未来这十年，我必须处于这种紧张的状
态了，以后...

Now again, emotional commitment is not enough. It is
a necessary condition apparently. And I think I can tell
you the reason why. Everybody who has studied
creativity is driven finally to saying, ``creativity comes
out of your subconscious.'' Somehow, suddenly, there
it is. It just appears. Well, we know very little about the
subconscious; but one thing you are pretty well aware
of is that your dreams also come out of your subconscious.
And you're aware your dreams are, to a fair extent, a
reworking of the experiences of the day. If you are deeply
immersed and committed to a topic, day after day after
day, your subconscious has nothing to do but work on
your problem. And so you wake up one morning, or on
some afternoon, and there's the answer. For those who
don't get committed to their current problem, the
subconscious goofs off on other things and doesn't
produce the big result. So the way to manage yourself
is that when you have a real important problem you
don't let anything else get the center of your attention -
you keep your thoughts on the problem. Keep your
subconscious starved so it has to work on your problem,
so you can sleep peacefully and get the answer in the
morning, free.
日思夜想到潜意识都参与进来。

If you do not work on an important problem, it's unlikely
you'll do important work. It's perfectly obvious. Great scientists
have thought through, in a careful way, a number of
important problems in their field, and they keep an eye
on wondering how to attack them. Let me warn you, `important
problem' must be phrased carefully. The three outstanding
problems in physics, in a certain sense, were never worked
on while I was at Bell Labs. By important I mean guaranteed
a Nobel Prize and any sum of money you want to mention.
We didn't work on (1) time travel, (2) teleportation, and (3)
antigravity. They are not important problems because we
do not have an attack. It's not the consequence that makes
a problem important, it is that you have a reasonable attack.
That is what makes a problem important. When I say that
most scientists don't work on important problems, I mean
it in that sense. The average scientist, so far as I can make
out, spends almost all his time working on problems which
he believes will not be important and he also doesn't believe
that they will lead to important problems.
很多时候问题重要并不是由于其结果，而是你有一个解决
的基本想法。

To end this part, I'll remind you, ``It is a poor workman who
blames his tools - the good man gets on with the job, given
what he's got, and gets the best answer he can.'' And I suggest
that by altering the problem, by looking at the thing differently,
you can make a great deal of difference in your final
productivity because you can either do it in such a fashion
that people can indeed build on what you've done, or you can
do it in such a fashion that the next person has to essentially
duplicate again what you've done. It isn't just a matter of the
job, it's the way you write the report, the way you write the
paper, the whole attitude. It's just as easy to do a broad,
general job as one very special case. And it's much more
satisfying and rewarding!
能最大程度利用好现有资源才是好的研究人员。

There are three things you have to do in selling. You have to
learn to write clearly and well so that people will read it, you
must learn to give reasonably formal talks, and you also must
learn to give informal talks. We had a lot of so-called `back
room scientists.' In a conference, they would keep quiet. Three
weeks later after a decision was made they filed a report
saying why you should do so and so. Well, it was too late.
They would not stand up right in the middle of a hot conference,
in the middle of activity, and say, ``We should do this for these
reasons.'' You need to master that form of communication as
well as prepared speeches.
如何 sell 自己的 idea。

You find this happening again and again; good scientists will
fight the system rather than learn to work with the system
and take advantage of all the system has to offer. It has a
lot, if you learn how to use it. It takes patience, but you can
learn how to use the system pretty well, and you can learn
how to get around it. After all, if you want a decision `No', you
just go to your boss and get a `No' easy. If you want to do
something, don't ask, do it. Present him with an accomplished
fact. Don't give him a chance to tell you `No'. But if you want a
`No', it's easy to get a `No'.
利用还是 fight，这个值得思考...

It depends upon the field. I will say this about it. There was a
fellow at Bell Labs, a very, very, smart guy. He was always
in the library; he read everything. If you wanted references, you
went to him and he gave you all kinds of references. But in the
middle of forming these theories, I formed a proposition: there
would be no effect named after him in the long run. He is now
retired from Bell Labs and is an Adjunct Professor. He was
very valuable; I'm not questioning that. He wrote some very
good Physical Review articles; but there's no effect named
after him because he read too much. If you read all the time
what other people have done you will think the way they thought.
If you want to think new thoughts that are different, then do
what a lot of creative people do - get the problem reasonably
clear and then refuse to look at any answers until you've thought
the problem through carefully how you would do it, how you
could slightly change the problem to be the correct one. So
yes, you need to keep up. You need to keep up more to find
out what the problems are than to read to find the solutions.
The reading is necessary to know what is going on and what
is possible. But reading to get the solutions does not seem
to be the way to do great research. So I'll give you two
answers. You read; but it is not the amount, it is the way you
read that counts.
只管读书是没有用的。

You have to change. You get tired after a while; you use up
your originality in one field. You need to get something nearby.
I'm not saying that you shift from music to theoretical physics
to English literature; I mean within your field you should shift
areas so that you don't go stale. You couldn't get away with
forcing a change every seven years, but if you could, I would
require a condition for doing research, being that you will
change your field of research every seven years with a
reasonable definition of what it means, or at the end of 10
years, management has the right to compel you to change.
I would insist on a change because I'm serious. What happens
to the old fellows is that they get a technique going; they
keep on using it. They were marching in that direction which
was right then, but the world changes. There's the new direction;
but the old fellows are still marching in their former direction.
研究必须与时俱进，这点也很重要，不能一棵树上吊死。

一路顺利，相信您在牛棚能够实现真正的梦想！
注意身体，多多保重！
