In Praise of Slow – How a Worldwide Movement is Challenging the Cult of Speed


People who know me say that I am a passionately fast person. That is why when I saw this book in the bookstore; I was attracted by both the title and the illustration on the cover. I bought it just to see how the writer argues his case.

Busy people like me are always on the run for more time but God is fair. We all have only 24 hours. To make the best of time, we rush and multi-task and feel proud of ourselves for being efficient. We are fervent worshippers of the Cult of Speed. But every now and then as things become quieter, there is deep down from the bottom of my heart a fear, fear that I am stretching myself too far, fear that I am burning the candle at both ends and the ultimate fear that I would any minute drop dead. Is that what life is supposed to be? There are so many places I would love to visit, grandchildren I would love to see them grow up and the list does not end here. I have to slow down. This book has given me all the good reasons to take life easy.

The writer, Carl Honore, emphasizes right at that his book is not a declaration against speed since we owe so much to speed which “has helped to remake our world in ways that are wonderful and liberating.” He says that all he wants us to stop and think is that “some things cannot, should not, be sped up.” When we force speed, “there is a price to pay.” In fact, there is a Chinese idiom epitomizing the same message: the desire to speed things up ends in not achieving anything at all.

When we examine our own life, this does bring an echo. How many times in the morning when we boot our computer, we are impatient and keep clicking the cursor and the computer is down? How often do we see people getting choked because they are swallowing too fast? Have ever slipped and fallen because we are rushing? These are but “cheap” prices we are paying for being fast. Think of the higher costs we might have to pay because of the fast life we have. Drivers cut lane and tail the car in the front in order to arrive faster. But such kind of road manner is the cause of most traffic accidents. Instead of enjoying our food at the table, we gobble our lunch washing it down with a coke. All these are absolutely “dehumanizing” for we feel a sense of guilt when we wind down and at a loss when we have time in hand to kill.

The book points out in greater details how the Cult of Speed is bringing devastating repercussions on the environment. When farmers do not have the patience to see their chickens or corn grow naturally, they start feeding them with pills. We desire to look physically fit and yet feel annoyed to work out for it. We only want quick fix and so take slimming pills or undergo plastic surgery and we suffer fatal effects.

The book makes us think. There is no urgency to finish it at one go. Just savour one or two chapters when you have time. Take it slowly. After all, that is what the book is about.

"Why I am not a Christian: and Other Essays on Religion and Related Subjects" recommended by Mr. Chan


羅素(Bertrand Russell)是二十世紀最具影響力的哲學家之一,也是我最敬重的數學家之一。最先聽到他的名字是在高中數學課,數學老師是位數學痴,動不動就跟我們說數學如何奧妙。不過對同學來說,數學最奧妙的地方可能是考得好就能在大學選讀較好的科目。畢竟開展人生要比展開多頂式實際得多。那時自己對數學的認識也就是學校教的那些,談不上有什麼興趣,甚至功課交不足,課也沒心聽。但老師說的羅素悖論,第三次數學危機等,卻漸引起我的興趣。自己看書,漸漸知道數學基礎在上世紀初對哲學影響甚深,大大促進了分析哲學和數理邏輯的發展,而羅素正是當中的重要人物。從數學中看到豐富的哲學問題,加上老師不住勸導,我才不致荒廢學業。說起來,羅素和那位老師正是令我選擇讀數學的人。

羅素是哲學家,其數學知識其實還未達大師境界。不過這個數理邏輯學家卻憑獨到的觀察,發現集合論竟暗含自相矛盾的「羅素悖論」,對數學的影響力比一般數學家還大。集合論仍數學的基石,集合論有矛盾即表示一向被視為最可靠的數學竟暗含自打嘴巴的恆錯命題。可貴的是羅素不同一般大數學家般留在象牙塔,用「只替不替自己理髮的人理髮的理髮師」來向大眾解釋「羅素悖論」;又用鞋和襪的分別來解釋何為「選擇公理」。這個百科全書式學者震動完數學和哲學界,轉頭還拿了個諾貝爾文學獎。

喜歡羅素,除了因為他的學養,也因為他的魅力。沒有魅力的學者對其伴侶而言就是家中的一部發聲百科全書再加送排泄物。有次羅素接受電視台訪問,主持請他預先看看將會問他的問題,讓他準備一下。羅素拒絕,稱他不是演員,不需要這樣。急才和自信故然重要,但我認為真正原因其實隱藏在他的智慧回答裡。羅素是理性主義的代表,一心要對抗迷信,說話大膽,不會因為怕誰而繞圈子說話,所以因此得罪了不少保守的政客,讓他多受冤屈。一個坐牢也不怕的頂天立地的人,會為了取悅電視觀眾而改變回答內容嗎?

羅素的大謄言論可在Why I am not a Christian: and Other Essays on Religion and Related Subjects 看到。幾十年前寫的書,現在社會上仍有那些問題。當年看的是同學父親送的中文版,現在英文版大書局一定有,中文版則很難找到。家中的那本,願送贈有心(有心看)人。其實羅素大概是眾文學獎得主文字寫得最淺白的一位,大家不妨看原文。

宋瑾瑜老師為你紹介《訓練思考能力的數學書》


書名: 《訓練思考能力的數學書》
作者: 岡部恆治
出版社: 究竟出版

內容簡介:
數學是一種思考訓練的教育,不只告訴學生某件事是這樣,而是讓學生研究為什麼是這樣,更重要的把一串一串的事件連成途徑去思考,去推理。

此書透過日常小問題的解決,籍以探討出數學的本質。可讀性相當高。

稍微動動腦,就可以化繁為簡。一本幫助你拋開繁雜的計算和公式背誦,從思考入手的「聰明式數學」。

在日本出版後引起教育界與媒體熱烈討論,2002年日本最暢銷的數學書。

數學是一門化繁為簡的知識;而數學性的思考能力,可以幫助我們學習「什麼是問題核心,什麼是可忽略的」,藉以掌握事物的本質。在現代生活中,這種洞察本質的能力愈形重要,而數學是少數能夠對此加強訓練、建立邏輯來對應的學問。
本書透過高斯、費瑪與阿基米德等偉大數學家的思考法,與日常生活中的智慧相互輝映,讓讀者在提昇思考力的同時,也能認識數學的本質及美感。

Book Recommendation – Cheung Chun Miu


The book I am recommending is called “Who moved my cheese”. It is a parable written by Dr. Spencer Johnson. In reality, the society is often changing, thus we need to face changes from time to time. The way we deal with changes usually determines whether we’ll succeed. As a result, learning to face changes is a really important part of our life. The story “Who moved my cheese” talks about four characters, representing four kinds of people, pursuing cheese in a maze, dealing with changes of the environment. It finally comes to a conclusion that we should always prepare ourselves to adapt to a new environment in order to succeed. I recommend this book to all students since it’s a meaningful book and the language used is not difficult that all students can understand it.
