有趣的詭辯例子

節錄自 於惠棠 之 《故事裡的詭辯術》

好讀網站 見到這本書(連結),例子很有趣,和大家分享分享。



麵條我沒有吃

某公擅長詭辯,又喜歡佔小便宜。有一次他去飯館吃飯,先要的是麵條,服務員端來的是辣麵,他不想吃 ,就讓服務員換了一盤包子,吃過之後不付款就走。

服務員對他說:「您吃的包子還沒有交錢呢!」

此人 說:「我吃的包子是用麵條換的。」

服務員說:「麵條你也沒有交錢。」

此人又說:「麵條我沒有吃呀! 」氣得服務員一時說不出話來。


一個人有三個頭

某甲對某乙說:「我能證明『一個人有三個頭』。」

乙說:「願聞高見。」

甲說:「每個人有一個頭,沒有人有兩個頭,一個人比沒有人多一個頭,所以,一個人有三個頭。」

乙雖然知道甲的論證是錯誤的,但不能指出錯在何處。



大膽刁民,本官何曾虧了你

從前有一個縣官要買金錠,店家遵命送來兩隻金錠。縣官問:「這兩隻金錠要多少錢?」店家答:「太爺 要買,小人只按半價出售。」縣官收下一隻,還給店家一隻。

過了許多日子,他不還帳,店家便說:「請太爺賞給小人金錠價款。」縣官裝作不解的樣子說:「不是早 已給了你嗎?」店家說:「小人從沒有拿到啊!」縣官拍案大怒道:「大膽刁民,本官要你兩隻金錠,你說只收半價,我已把一隻還給了你,就折合那一半的價錢,本官何曾虧了你!」

店家聽罷,苦不堪言。


你現在不是也在講話嗎

一個電影院裡正在放電影,觀眾席上有幾個人高聲說話,旁邊的一位觀眾勸他們說:「請你們不要講話,好嗎?」其中一個小伙子倒打一耙說:「嘿嘿,你現在不是也在講話嗎?」



快把飯錢算給巴依

在《阿凡提的故事》一書中,講了一個《飯錢》的故事:

有一個窮人找到阿凡提說:「咱們窮人真是難啊!昨天我在巴依(即財主)開的一家飯館門口站了一站,巴依說我聞了他飯館裡的飯菜的香味,叫我付錢,我當然不給。他就到喀孜(即宗教法官)跟前告了我。喀孜決定今天判決。你能幫我說幾句公道話嗎?」

「行,行!」阿凡提一口答應下來,就陪著窮人去見喀孜。

巴依早就到了,正和喀孜談得高興。

喀孜一看見窮人,不由分說就罵道:「真不要臉!你聞了巴依飯菜的香氣,怎麼敢不付錢!快把飯錢算給巴依!」

「慢著,喀孜!」阿凡提走上前來,行了個禮,說道,「這人是我的兄長,他沒有錢,飯錢由我付給巴依好了。」

阿凡提一邊說一邊從腰裡掏出一個裝銅錢的小口袋,舉到巴依耳朵旁邊搖了幾搖,一問巴依道:「巴依,你聽見口袋裡響亮的聲音嗎?」

「什麼?哦,聽到了!聽到了!」巴依說。

「好,他聞了你飯萊的香氣,你聽到了我的錢的聲音,咱們的帳算清了。」

阿凡提說完,拉著窮人的手,大搖大擺地走了。


空酒瓶等於裝滿酒的瓶

小趙、小錢、小孫、小李四人是同學,他們常聚在一起討論問題。有一天四人同桌吃飯,為桌上的半瓶酒爭論起來。

小趙說:這瓶子一半是空的。

小錢說:這瓶子一半是滿的。

小孫說:這有什麼好爭的,半空的酒瓶就等於半滿的酒瓶。

小李說:不對。如果「半空的酒瓶等於半滿的酒瓶」這個等式能夠成立,那麼我們把等式兩邊都乘以二:

半空的瓶乘以二,等於兩個半空的瓶,而兩個半空的瓶就是一個空瓶;半滿的瓶乘以二,等於兩個半滿的瓶,而兩個半滿的瓶就是一個裝滿酒的瓶。這樣,豈不是一個空酒瓶等於一個裝滿酒的酒瓶嗎?


父在母先亡

一個有迷信思想的人,請算命先生算一下自己的父母的享壽情況。

算命先生照例先問了一遍來人及其父母的出生年月日,然後裝模作樣地屈指掐算了一會兒,於是回答說:

「父在母先亡。」

這個人聽了以後沉思片刻,付錢而去。

為什麼求卜者對算命先生的話不懷疑,付錢而去呢?這是因為「父在母先亡」這句話有歧義,人們對它可以有不同的理解,或者說它可以表達不同的判斷:

父親尚在,母親已經去世;
父親先於母親而亡,即母親尚在,父親已經去世。

而且這兩種解釋不僅適用於現在,也適用於過去和將來。

我吸煙時從不工作

某工廠的一位車間主任看見工人小王上班對在車間裡吸煙,就批評他說:「廠裡有規定,工作時禁止吸煙!」

小王漫不經心地回答說:「當然,我吸煙時從不工作。」

誓聯

清人黃圖珌編過一則《誓聯》的笑話。說的是有個縣官上任伊始,便在堂上高懸一副對聯:

得一文,天誅地滅;
徇一情,男盜女娼。

但是,實際上他卻貪贓枉法。有人指責他言行不一,忘記了誓聯。

縣官辯解道:「我沒有違背誓言啊,因為我得到的不是一文錢,受賄徇情也不是一次啊!」

「靠得住」嗎

魯迅先生在一篇雜文中講了這樣一件事:

A: B,我們當你是一個可靠的人,所以幾種關於革命的事情,都沒有瞞著你。你怎麼竟向敵人告密去了?

B: 豈有此理!怎麼是告密!我說出來,是因為他們問了我呀。

A: 你不能推說不知道嗎?

B: 什麼話!我一生沒有說過謊。我不是這種靠不住的人!(《且介亭雜文末編》:「半夏小集」(五),第一零七頁)

這場官司要不要打

古希臘著名哲學家、詭辯家普羅塔哥拉曾公開設館教人辯論之術。他收了一個想當律師的學生,名叫愛瓦梯勒士。師生簽訂合同:學生先交一半學費,另一半學費待學生畢業後第一次出庭為人打官司勝訴後交付 ;如果官司敗訴就毋須再交這一半學費。

愛瓦梯勒士畢業後並未從事律師職業,也不交那一半學費。老師等得不耐煩,就向學生索取,學生執意不給,師生要訴諸法庭解決。老師對學生說,這官司打起來對你沒有好處。因為:如果我打贏了,根據法庭判決,你必須給我學費;如果我打輸了也就是你打贏了,根據當初簽訂的合同,你也必須給我學費(合同規定,愛瓦梯勒士第一次打贏官司應交學費);或者我打贏了,或者我打輸了;所以,你都必須給我學費。

愛瓦梯勒士聽後不甘示弱,他對老師說,我看這官司打起來實際上對你不利。因為:如果我打贏了,根據法庭判決,我當然不給你學費;如果我打輸了,根據當切簽訂的合同,我無須再交學費(合同規定,愛瓦梯勒士第一次打輸了官司,就不要交另一半學費);或者我打贏了,或者我打輸了;所以,我都不應付給你學費。

這就是邏輯史上著名的「半費之訟」。

How I Trade and Invest In Stocks and Bonds (Richard D. Wyckoff)



Wyckoff 是某天在聽香港電台《投資新世代》時經濟日報的石鏡泉介紹的,看看維基百科(link),才知Wyckoff是20世紀初的財經名人!

在網上尋找他的文章,好好彩,仍找到很多,加上迎來買了部Kindle 3,所以閱讀電子書更加方便。

首先看的是”How I Trade and Invest In Stocks and Bonds”(Internet Archive有免費copy,1924年版,見link),雖然是scanned pdf,不過有OCR,所以可以search,很方便。

雖然沒有技術分析,Richard在書中詳細講他1的投資(或投機)心法,最重要是這些論據沒有因時間而變成失效,以下是我在本書的一些jottings,希望同大家分享:

頁17
All he asks is to be told "something good." That is not speculation, it is gambling...

頁34
I found that most of (the people) wanted to lean - not to learn. They just drifted along, guided by hope of profit and pursued by fear of loss.

頁45
Before I go any further, let me say that not every man is adapted to trading in stocks. In fact, very few are fitted for the work if it is undertaken as an art, a business, a profession, or whatever else you wish to call it.

頁75
Never get married to a security.

頁88
It is poor policy, I find, to wait for Opportunity to knock at your door.

頁143
These points are about equally divided between investment and speculation, but it is so difficult to determine which one begins and the other ends that in many cases I shall be obliged to treat them in combination.

頁144
IF ONE IS NOT ADAPTED TO TRADING HE SHOULD PROVE IT TO HIS OWN SATISFACTION AND THEN ABANDON THE BUSINESS. - He should then attempt to become an intelligent and successful investor. Failing of this, he should turn to savings banks and mortgages or other non-fluctuating mediums for the investment of his funds.

Kindle 2011 Hong Kong Calendar

I have brought the Kindle 3. The advantages of Kindle 3 over previous version is:
  • it is much cheaper (the Wifi version is only US$139!)
  • it natively supports Simplified and Traditional Chinese without any additional hacking
After reading many "free" e-books found on internet, I must say I am very satisfied with my new toy so far, thanks to its appropriate footprint and long battery life.

I then start to explore whether I can create a Kindle ebook myself.

I am not a writer and therefore have no content to share. But why not make a Kindle app? Franking speaking I am not using KDK (Kindle Development Kit). But using the built-in annotation and indexing mechanism of the Kindle mobi format, I find I can make a calendar.


If you have interest, please install a copy yourself:

(1) save the attached prc file (link) using "Save Link As"
(2) transfer the prc file to your Kindle document folder via USB or your Kindle email account

Since I have added the Lunar Calendar, it has Traditional Chinese characters. But I have not tested the compatibility on older Kindle models.

You can create your Appointments as follows:
  • press the 5-way as usual to your target date (similar to creating notes)
  • enter your appointment details


Afterward, your schedule will be shown on the date with a superscript note-mark as follows:



(the yellow-highlight is added by me to draw your attention - Kindle does not support color display yet!)

Hope you like it.

Composing a HTML table in Gmail

In Hotmail, I can directly edit the html codes during composing an email. However, in Gmail, I cannot have this feature.

Moreover, Gmail does not have the built-in function to compose a table.

Recently, I accidentally find that the copy-and-paste feature in the Gmail preserves the formatting. So following the track, I find I can actually create a table simply by copy-and-paste an empty table from another editor (like Word)!

Though I cannot do further formatting (like column width adjustment), I find I already overcome one of the greatest deficiencies.

My Facebook Friends' Profile

My original aim to us Facebook is to make reunion to my old school-mates and friends. It works (though I find some of my friends are very reluctant to open a Facebook account).

Now, I nearly log on Facebook every day. I find that my friends' activities are quite "strange":

- a few (less than 10%) are very active and makes postings every day
- many behave like a whale (surfacing to water a moment, makes comments) and disappear for months
- half of them actively play FB games (though I never try one)

Somehow, to my disappointment, I find that the posting on FB is just on acquaintance level and the communication level is very superficial.

Creating Scrolling Banner using Gimp

This is my second Gimp script. (The first is 'Gimp Polaroid Filter' published in Dec 2009

Why I write this second script is triggered by my another very recent blog 'Scrolling Banner using CSS', in which I mentioned I have previously used animated GIF to give scrolling banner effect.

Yes, creating animated GIF is very tedious previously. But I can write Gimp Script-fu. Why not automate the process? So, I write my second Gimp script using the Scheme language.

Script filename: scroller.scm (the zipped form can be downloaded from here

Installation Steps: In my Windows environment, you can simply unzip the file and move it to 'C:\Program Files\Gimp-2.0\share\gimp\2.0\scripts'

Example of using the script:

I first create a new image with a 'Hello' text. The new script is accessible via Filter | Animation | Scroller.



In the screen dump above, you can see the Scroller item. But it is still dimmed because Gimp does not like the text layer. You need to flatten the image first.



The Scroller Script-Fu dialogue has the following options:

  • Work on Copy: If checked, the script will duplicate the image file so that you think it is safer. Anyway, even you do not check this box, you can still use Gimp's undo feature to roll back
  • Scrolling Vertical: If unchecked, the scrolling direction will be horizontal
  • Scrolling Up /Left: If unchecked, the scrolling direction will be scrolling down or right
  • Flatten image: This check box is useful in case your image has multiple layers before



After exaction of the script, you can see Gimp has created many layers (as down in the Layer Dock above



You can use Gimp's Playback feature to preview the effect as in the above menu.



If you are satisfied with the result, you can export the result to a GIF file. Please remember to select 'Save as Animation' (highlighted option)



For the frame disposal option, I recommend to select 'One frame per layer (replace) because in my script, each new layer is a full size layer. I find the delay per frame at 100 ms is usually acceptable. (By the way, sending a too low value may not be effective in many web browsers).

The following is final result (displayed as GIF)

IT consumer or IT producer

Sometime ago, I read an article on notebook PC product positioning. The product manager mentioned something like they have a series of notebook PC's for a wide spectrum of users - from consumers to producers. They think IT consumers takes activities like web surfing, video watching etc, while IT producers need more powerful PC for content generation etc etc.

I cannot totally agree with this simple demarcation because I think some gamers' PC configurations are even more powerful than some servers nowadays (e.g. in terms of graphical processing power, Hard disk capacity, etc) and they are still though at consumer - am I right?

But this division of consumer vs. producer let me recall my old memories of economy classes. Consumer and Producers only appears in different context. For example:
A factory worker of course is a producer in the conventional context. But during his/her course of manufacturing, he/she will also consume some raw materials, although we can argue that the 'net' economic value of his final product should be greater than the raw materials.

From another point of view, a factory worker, after taking his salary, will consume on food, entertainment and other services, which are provided by other so caller producers.

Okay, back to the IT world. In fact, I find actually the majority of the users are just consumers. Take Facebook as example. Facebook is a collaboration platform, in which users should contribute the contents symmetrically. However, in my groups of friends, more than 80% the content generated are created by less than 20% of my friends (so-called 80-20 rule). I also found that many of my friends has logged on (from the on-line status) but never says a word on the wall or comment other's status.

I have also an IT acquaintance, who is very good at IT skills, never joined any forum, Facebook groups etc. He will visit forums every night to see others' postings and blogs. He just remains as a silent user! He has many excuses - web security, political audit, etc etc. But I just see these are excuses.

Scrolling Banner using CSS

I used to create animated GIF for scrolling web banners. However, this is very time-consuming.

Yes, I know there are the following alternatives:

  • commercial GIF creator with canned animation effect (but I do not want to pay)
  • free JavaScripts using CSS (My personal principle is "Simple is beautiful and while my understanding on the complicated codes is limited and I cannot be sure the compatibility of various browser versions. A final word, I do not like a white-out effect, which is a limitation I observe in many, if not all, of these JavaScripts.)

Therefore I start to resort to CSS and JavaScript.

My aim is very simple:
  • - the scrolling banner can be in either vertical or horizontal direction
  • - the codes (CSS or JavaScript) should be in a few lines only
  • - the scrolling should be repeating and there is no blank instance

I nearly forgot to tell one limitation of my solutions is that the banner content is in graphical (i.e. not text) format.

Implementation Procedure
(1) Create a graphical banner. My preference is GIF format because its lossless pixel compression (though color depth compression is lossy - but this is not a big problem because the banner is more poster like and should have not many colors.). Another advantage of GIF is its support of transparent color.

(2) In your html codes, insert a <div> like
<div id="'scroll_div'" style="display: block; width: 400px; height: 20px; background: url(banner.gif) repeat-y 0 0px;"></div>
Remarks:
  • scroll_div is the DIV id for subsequent JavaScript manipulation
  • width and height are the associated dimension of the graphical banner
  • banner.gif is the filename of the graphical banner
  • repeat-y: this attribute is very important, because, as I said before, I like the banners to scroll with continuous repeating pattern.

(3) Create the following JavaScripts
var cur_ypos;
var div_height;
function init_scroll(){
cur_ypos = 0;
div_height = parseInt(document.getElementById("scroll_div").style.height);
div_bgr_pos = document.getElementById("scroll_div").style.backgroundPosition;
window.setInterval('scroll_banner()', 150);
}
function scroll_banner() {
cur_ypos++;
if (cur_ypos == div_height) cur_ypos = 0;
document.getElementById("scroll_div").style.backgroundPosition = '0 -' + cur_ypos + 'px';
}
Remarks:
  • The variable div_height is just implemented for the sake of efficiency because I do not want to evaluate the division height on each call
  • The key scrolling mechanism is to modify the CSS vertical background-position by one pixel
  • The scrolling speed can be modified by changing the timer value (the example here is 150 mill-seconds). Please note that there is no point to set a too small values because most JavaScript implementation cannot afford a too short timer.

(4) Start the script using the Body onload
<body onload="init_scroll();">

Demonstration:
Sorry that I cannot demonstrate the effect in Blogspot because I find I cannot manipulate ad hoc JavaScript in the Blogspot environment. So, I use again animinated GIF for demonstration:

大師,點解我每次感冒…我都會咳?

這個成藥廣告,是繼《你值得擁有》(見我另一編Blog)我最覺得反感的!由於主角引用宿命論云云,所以每次在電視看到這個廣告,我都會自己加插以下旁白:

大師,點解我每天吃飽飯後,都要上廁所?
點解我心情緊張,都會手心出汗?
點解我每次消化不良,都要放屁?
等等…
大師,這是不是宿命呀?

人就是這樣,對於一些生命常態,但自己主觀不能接受的,就抱怨是宿命,將自己在事件上的角色和責任抹掉。

相反,對於一些自己「有利」的現象,就歸功於自己的力量。

「宿命」真是這樣的嗎?

塔勒布 在 【黑天鵝】的名句

舊年(2009)在深圳書城買了本"THE BLACK SWAN: The Impact of the Highly Improbable"中譯本,發覺題材非常新鮮,有很多發人心醒的內容。但由於是中譯本,始終不知原著的語句。

上星期,終於在圖書館借到原英文本(2007年版),現節錄一些我覺得非常有意思的內容,和大家分享:

Page xviii
Black Swan is an event with the following three attributes:

  1. Rarity – It lies outside the realm of regular expectations
  2. Extreme Impact – It carries an extreme impact
  3. Retrospective predictability – Human nature makes us concoct explanations for its occurrence after the fact, making it explainable and predictable.
Page xix
Black Swan logic makes what you don't know far more relevant than what you do know.

Why does reading the newspaper actually decrease our knowledge of the world?

Life is the cumulative effect of a handful of significant shocks.

Page xx
Our inability to predict in environments subjected to the Black Swan, coupled with a general lack of the awareness of this stage of affairs, means that certain professionals, while believing they are experts, are in fact not.

Page xxvii
You need a story to displace a story.

Ideas comes and go, stories stay.


Page 3
History doesn't crawl; it jumps.

Page 8
The human mind suffers from three ailments as it comes into contact with history, what I call the triplets of opacity. They are:

  1. the illusion of understanding, or how everyone thinks he knows what is going on in a world that is more complicated (or random) then the realize;
  2. the retrospective distortion, or how we can assess matters only after the fact, as if they were in a rearview mirror (history seems clearer and more organized in history books than in empirical reality); and
  3. the curse of learning - the overvaluation of factual information and the handicap of authoritative and learned people, particularly when they create categories - when they "Platonifiy."
Page 10
These events were unexplainable, but intelligent people thought they were capable of providing convincing explanations for them – after the fact. Furthermore, the more intelligent the person, the better sounding the explanation.

Page 21
(Financial) independence is person-specific: I have always taken aback at the high number of people in whom an astonishingly high income led to additional sycophancy as they became more dependent on their clients and employers and more addicted to making even more money.

Page 25
Publishers now have a theory that "truck drivers who read books do not read books written for truck drivers"
香港有沒有這些出版商呢?

Page 40
The uberphilosopher Bertrand Russell presents a particularly toxic variant of my surprise jolt in his illustration of what people in his line of business call the Problem of Induction.

Page 54
An acronym used in the medical literature is NED, which stands for No Evidence of Disease. There is no such thing as END, Evidence of No Disease. Yet my experience discussing this matter with plenty of doctors even those who publish papers on their results, is that many slip into the round-trip fallacy during conversation.

Page 59 footnote
Once your mind is inhabited with a certain view of the world, you will tend to only consider instances proving you to be right. Paradoxically, the more information you have , the more justified you will feel in your views.

Page 80
One death is a tragedy; a million is a statistics.

Page 96
Some people are like the turkey, exposed to a major blowup without being aware of it, while others play reverse turkey, prepared for big events that might surprise others.

Page 111
Recall the confirmation fallacy: governments are great at telling you what they did, but not what they did not do. In fact, they engage in what can be labeled as phony "philanthropy," the activity of helping people in a visual and sensational way without taking into account the unseen cemetery of invisible consequences.
咁似香港D區議員!

Page 112
Our neglect of silent evidence kills people daily. Assume that a drug saves many people from a potentially dangerous ailment, but runs the risk of killing a few, with a net benefit to society. Would a doctor prescribe it? He has no incentive to do so... A life saved is a statistics; a person hurt is an anecdote.

Page 120
My biggest problem with the educational system lies precisely in that forces students to squeeze explanations out of subject matters and shames them for withholding judgment, for uttering that "I don't know."

Page 152
We humans are the victims of an asymmetry in the perception of random events. We attribute our success to our skills, and out failures to external events outside our control, namely to randomness.

Page 181
The only criticism one might have of Hayek is that he makes a hard and qualitative distinction between social sciences and physics. He shows that the methods of physics do not translate to its social science siblings, and he blames the engineering-oriented mentality for this. But he was writing at the time when physics, the queen of sciences, seemed to zoom into our world. It turns out that even the natural sciences are far more complicated than that. He was right about the social sciences, he is certainly right in trusting hard scientists more than social theorizers, but what he said about the weaknesses of social knowledge applies to all knowledge. All knowledge.

Page 198
Randomness, in the end, is just unknowledge. The world is opaque and appearances fool us.
好有佛理!

Page 222
Luck is the grand equalizer, because almost everyone can benefit from it.

Page 225 footnote
The giant firm J.P. Morgan put the entire world at risk by introducing in the nineties RiskMetrics, a phony method aiming at managing people's risk, causing the generalized use of the ludic fallacy.

Page 226
True, we now have fewer failures, but when they occur...I shiver at the thought. I rephrase here: we will have fewer but more severe crises. The rarer the event, the less we know about its odds. It means that we know less and less about the possibilities of a crisis.

希望大家有同感!

不是小兒科的數字

近期在新聞報導常常聽到一些很大的數字,如多少百億興建高鐵,金融海嘯有關的天文數字等,令我覺得其實有多少人知道其真正「份量」?

有次在街上,聽到一母親教她的兒子數十進制:個、十、百、千、萬、十萬、百萬、千萬、億萬...我覺得愕然,為何會由千萬特跳到億萬呢?難怪現在的小孩不識理財了,因為連數數字也不懂!

我小學時學的,中國單位以萬為分位,西方則以千為分位,所以:

千萬以後是:萬萬(即億),十億,百億、千億、萬億、十萬億,百萬億、千萬億...

講起數數字,順便講一講「兆」。

中學時學十進制,知道兆是一百萬,所以電台FM頻道的兆赫是百萬Hertz。

但是台灣仍治用兆是萬億(即1012)(見維基百科 )

新聞報導員沒有加上附註,容易做成混亂!
