Pandemonium

E: Can you just, you know, like, just tell me the answer?

J: Sorry?

E: You know, the answer. To everything.

What’s the point of love if it’s just disappear?

There has to be meaning to existence, otherwise the universe is made of pain and I don’t like the thought of that.

So, tell me the answer!

J: The more human I become, the less things make sense.

But that’s part of the fun. Right?

E: What do you mean?

J: If there were an answer I can give you to, how the universe works, it wouldn’t be special. It would be just a machinery fulfilling its cosmic design. It would be just a big, dumb food processor.

But, since nothing seems to make sense, when you find something or someone that does, it’s euphoria.

.

In all of this randomness, in this pandemonium, you and Chidi found each other and you had a life together.

Isn’t that remarkable?

E: Pandemonium is from Paradise Lost. Milton called the center of hell “pandemonium”, meaning “place of all demons”.

I guess all I can do is to embrace the Pandemonium.

Find happiness in the unique insanity of being here, now.

潛行凶間 16.3

Inception 16.3

這段改編自 2010 年 8 月 13 日的對話。

.

怎料,當早所看的電影《潛行凶間》那麼應景,恰巧在主題中有「清醒夢」和「多層夢」。那就是為什麼我剛才說:

《潛行凶間》中的意念,你可以假想,有七成是真的。

知道這些有趣知識——原來世間上,是有「清醒夢」和「多層夢」——是有實質好處的。

例如,你會繼而知道,原來人是有「潛意識」的;而在一些清況下,「潛意識」的智力和能力,多過「顯意識」。但是,「潛潛意識」又再利害過「潛意識」。

再例如:

3. 多重自我

3.1 每一個人,其實有超過一個自我。

3.2 而每一個自我,其實有超過一個層次的意識。

至於在平日,怎樣可以存取到,各個層次的潛意識呢?

有太多的方法,有些是健康的,有些是自殘的,不能盡錄。現在只講一兩點。

健康的方法有,適量的睡眠。睡眠太多或太少,都到身體、顯意識和潛意識有害。睡眠太少的話,你的潛意識,沒有足夠時間,去整理日間接收了的資料。

自殘的方法有,患病。

.

「清醒夢」或「多層夢」,如果自然發生,你可以細心觀察。

但是,千萬不要主動去引發「清醒夢」或「多層夢」。它們時常發生的話,會破壞意識,脫離現實。

33 INT. HOLDING AREA

Quark and Sakonna are sharing the same cell.

QUARK
I hope you’re happy.

SAKONNA
I am a Vulcan. My emotional state is irrelevant.

QUARK
Well I’m a Ferengi. And my emotional state is very relevant. And right now, I’m miserable. And it’s all your fault.

SAKONNA
You were well paid for your assistance.

QUARK
Not well enough. Look, why don’t you just tell them what they want to know?

Sakonna just stares at him.

DEEP SPACE: “The Maquis, II” – 02/17/94 – ACT FOUR 42.

33 CONTINUED:

QUARK
(continuing, talking confidentially) I know the Cardassians can’t be trusted. I know that the Central Command would like nothing better than to destroy the Federation colonies in the Demilitarized Zone.

SAKONNA
Then you agree with our position?

QUARK
Not for a second.

SAKONNA
Why not?

QUARK
Because your position is… (searching for the right word) Illogical.

This takes Sakonna off guard.

SAKONNA
Do you propose to lecture me on logic?

QUARK
I don’t want to, but you leave me no choice. It all comes down to the third Rule of Acquisition.

(off her blank reaction)

You don’t know that one, do you?

SAKONNA
I am not well versed in Ferengi philosophy.

QUARK
Remind me to get you a copy of the Rules. You never know when they’ll come in handy. Now, the third rule clearly states,

Never pay more for an acquisition than you have to.

SAKONNA
Logical. But I fail to see how that applies to my situation.

DEEP SPACE: “The Maquis, II” – 02/17/94 – ACT FOUR 43.

33 CONTINUED: (2)

QUARK
You want to acquire peace. Fine.

Peace is good. But how much are you
willing to pay for it?

SAKONNA
Whatever it costs.

QUARK
That’s the kind of irresponsible spending that causes so many business ventures to fail.

You’re forgetting the third rule. Right now peace could be bought at a bargain price and you don’t even realize it.

SAKONNA
I find this very confusing.

QUARK
Then I’ll make it so simple that even a Vulcan can understand. The Central Command has been caught red-handed smuggling weapons to their settlers. So from now on, every ship approaching the Demilitarized Zone will be searched. Without the support of the Central Command, the Cardassian settlers won’t be so eager to fight.

SAKONNA
You forget the weapons they already have.

QUARK
They have weapons… you have weapons… everyone has weapons. But right now, no one has a clear advantage. So the price of peace is at an all-time low. This is the perfect time to sit down and hammer out an agreement. Don’t you get it… attacking the Cardassians now will only escalate the conflict and make peace more expensive in the long run. Now I ask you, is that logical?

Quark sits down, pleased with his performance.

Inception 16.2

這段改編自 2010 年 8 月 13 日的對話。

又例如:

2. 多層夢

有時,明明已經起了床,關掉了鬧鐘;怎料,「明明已經起了床,關掉了鬧鐘」這劇情,只是另一個夢——我仍然未醒來。結果,要醒了很多次,經歷很多層,才真正醒來。

而對我個人而言,最有趣的地方是,我在看《潛行凶間》之前一晚,正正發了「清醒夢」和「多層夢」。

我在看《潛行凶間》前的那個時期,身體長期不太舒服,可能是傷風或者感冒,導致有少許咳嗽。但是,在戲院內咳喇的話,會影響他人,所以可免則免。因此,在前一晚,因為知道明早要去看電影,我的潛意識對身體下令,要立即康復。那樣,一來令我腦部活躍,二來令我身體病發,引發了我的「清醒多層夢」。

怎料,當早所看的電影《潛行凶間》那麼應景,恰巧在主題中有「清醒夢」和「多層夢」。那就是為什麼我剛才說:

《潛行凶間》中的意念,你可以假想,有七成是真的。

On Lisp

paulgraham_2202_3475946

Lisp is an especially good language for writing extensible programs because it is itself an extensible program.

Because Lisp gives you the freedom to define your own operators, you can mold it into just the language you need. If you’re writing a text-editor, you can turn Lisp into a language for writing text-editors. If you’re writing a CAD program, you can turn Lisp into a language for writing CAD programs. And if you’re not sure yet what kind of program you’re writing, it’s a safe bet to write it in Lisp. Whatever kind of program yours turns out to be, Lisp will, during the writing of it, have evolved into a language for writing that kind of program.

Inception 16

這段改編自 2010 年 8 月 13 日的對話。

d_2018_02_18__19_10_12_PM_

這幾個月來,我跟一位來自大學時代的朋友,討論一些較為深刻精采,一般人也不會討論的話題。怎料,《潛行凶間》竟然囊括那些深刻精采話題,之中的一大部分。

在我朋友的同意和鼓勵下,我把那些對話錄了音,再化成文字。那就彷彿是把那些意念,由氣體凝結成液體。怎料,該電影卻把那些意念,再由液體凝固成固體。

我把對話化成文字,莫非都是為了避免,同一堆說話,再講一次。同一堆說話講第二次,並不是一個快樂的過程。有了文字版後,當有其他朋友需要那些意念時,我就可以引述我的文章,從而開發下一個層次的話題。

但是,有了《潛行凶間》這電影後,凡是之中有的意念,我的相關文章,都可以一概置之不理;因為,我只要介紹該電影,給對那些意念,有興趣的朋友就可以。

電影內,有太多超凡的意念,不能一次過講得完。你們可以分開幾次來問我,例如:

1. 清醒夢

1.1 有些人在某些時候,在夢知道自己在發夢,卻又可以保持住,發夢的狀態。

1.2 那些人之中的部分人,在那些清醒夢時候的部分時候,甚至可以控制著,那些夢境的劇情演變。

你有沒有試過,在夢裡面,知道自己在發夢?

(CPK:未。不過,我的姐姐試過。)

我中學時代,有一次清醒夢時,刻意留意一棵樹。

我發現,原來夢中的東西,不只有黑白色。我不單看到,那棵樹的葉是綠色的,而且,還可以見到,那些樹葉中的每一塊。

《潛行凶間》中的意念,你可以假想,有七成是真的。

又例如:

2. 多層夢

有時,明明已經起了床,關掉了鬧鐘;怎料,「明明已經起了床,關掉了鬧鐘」這劇情,只是另一個夢 — 我仍然未醒來。

3. 多重自我

3.1 每一個人,其實有超過一個自我。

3.2 而每一個自我,其實有超過一個層次的意識。

Intellectual Headaches

Game design

They got the key, and then some other stuff happened, and then they reached the door, and were able to open it; but “acquiring the key” and “opening the door” were stored as two separate, disconnected events in the player’s mind.

If the player had encountered the locked door first, tried to open it, been unable to, and then found the key and used it to open the door, the causal link would be unmistakable. You use the key to open the locked door, because you can’t open the locked door without the key.

Math education

I’ve drawn parallels between game design and education before, but it still took me a while to realize that problem-solution ordering issues crop up just as often in the classroom as they do in games.

Remember how, in high school math class, a lot of the work you were doing felt really, really pointless?

Consider Dan Meyer’s question for math educators: if math is the aspirin, then how do you create the headache?

In other words: if you introduce the solution (in this case, a new kind of math) before introducing the kind of problems that it’s meant to solve, the solution is likely to come across as pointless and arbitrary. But if you first let students try to tackle these problems with the math they already understand, they’re likely to come away with a kind of intellectual “headache” – and, therefore, to better understand the purpose of the “aspirin” you’re trying to sell.

If you have an apple and I have an apple, and we exchange apples, we both still only have one apple. But if you have an idea and I have an idea, and we exchange ideas, we each now have two ideas.

— George Bernard Shaw

.

. . . it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. Its peculiar character, too, is that no one possesses the less, because every other possesses the whole of it. He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.

That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, …
