書摘︰《歷史資本主義》


Immanuel Wallerstein (就是在政治經濟學和國際關係裡非常著名的「世界體系理論」的創始人)的小書 "Historical Capitalism" 之前在日本旅行時讀完,書雖小,但理論卻非常宏大。 Wallerstein 雖然深受馬克思的政治經濟學影響,但他的學說對傳統的左
翼理論作出了很多修正,例如他認為過往所發生過的社會主義革命/反體制運動都只左右了國際間的權力平衡,並沒有脫離資本主義這個歷史體系,甚至反而加固了資本主義。我把較重要的修正抄下來,嫌太長的可以根據中文詮腳選段來讀。


(一)帝國主義


對於帝國主義擴張的解釋, Wallerstein 認為一般的說法「過剩商品需要尋找新市場」並不合乎事實,較恰當的解釋是資本家需要開發更廉價的勞動力︰
"Areas external to historical capitalism have on the whole been reluctant purchasers of its products, in part because they didn't 'need' them in terms of their own economic system and in part because they often lacked the relevant wherewithal to purchase them. To be sure there were exceptions. But by and large it was the capitalist world that sought out the products of the external arena and not the other way around. Whenever particular loci were militarily conquered, capitalist entrepreneurs regularly complained of the absence of real markets there and operated through colonial governments to 'create tastes'.

The search for markets as an explanation simply does not hold. A much more plausible explanation is the search for low-cost labour forces. It is historically the case that virtually every new zone incorporated into the world-economy established levels of real remuneration which were at the bottom of the world-system's hierarchy of wage-levels."

(二)資本主義革命

對於由封建主義到資本主義的過渡, Wallerstein 認為是同一個統治階級的內鬥和自我轉型,而並非一個新階級推翻舊階級的過程

"The economic arena of feudal Europe was going through a very fundamental, internally generated, crisis in this period that was shaking its social foundations. Its ruling classes were destroying each other at a great rate, while its land-system (the basis of its economic structure) was coming loose, with considerable reorganization moving in the direction of a far more egalitarian distribution than had been the norm. [...] Things were indeed falling apart. Had Europe continued on the path along which it was going, it is difficult to believe that the patterns of medieval feudal Europe with its highly structured system of 'orders' could have been reconsolidated. Far more probable is that the European feudal social structure would have evolved towards a system of relatively equal small-scale producers, further flattening out the aristocracies and decentralizing the political structures.
... But it is clear that the prospect must have appalled Europe's upper strata --- appalled and frightened them, especially as they felt their ideological armour was disintegrating too. Without suggesting that anyone consciously verbalized any such attempt, we can see by comparing the Europe of 1650 with 1450 that the following things had occurred. By 1650, the basic structures of historical capitalism as a viable social system had been established and consolidated. The trend towards egalitarianization of reward had been drastically reversed. The upper strata were once again in firm control politically and ideologically. There was a reasonably high level of continuity between the families that had been high strata in 1450 and those that were high strata in 1650."

讀者應該會留意到 Wallerstein 比馬克思主義者更強調政治力量的角色,他認為技術的發展並非資本主義的原因而是其結果,是資本主義為發展科技帶來誘因,因為新發明意味著可以獨市的新商品。

Wallerstein 也談到資本家的內鬥會以「民主」、「自由」等口號包裝甚至以「革命」形式呈現︰

"Sometimes, however, they have been over larger 'constitutional' issues which determine the rules governing the conduct of shorter-run struggles, and thus the likelihood of one fraction or another prevailing. Whenever these struggles were 'constitutional' in nature, they required greater ideological mobilization. In these cases, we heard talk of 'revolutions' and 'great reforms' and the losing sides were often given opprobrious (but analytically inappropriate) labels. To the extent that the political struggles for, say, 'democracy' or 'liberty' against 'feudalism' or 'traditon' have not been struggles of the working classes against capitalism, they have been essentially struggles among the accumulators of capital for the accumulation of capital. Such struggles were not the triumph of a 'progressive' bourgeoisie against reactionary strata but intro-bourgeois struggles. 
Of course, using 'universalizing' ideological slogans about progress has been politically useful. It has been a way of associating class struggle mobilization to one side of intra-accumulator struggles. But such ideological advantage has often been a double-edged sword, unleashing passions and weakening repressive restraints in the class struggle."

(三)社會主義革命

他也解釋了在資本主義世界中革命造反為何比在先前的歷史階段更困難︰

"...generally speaking, rebellion as a technique has worked only at the margins of central authority, particularly when central bureaucracies were in phases of disintegration." 
"The fact that states were located in an interstate system meant that the repercussions of rebellions or uprisings were felt, often quite rapidly, beyond the confines of the immediate political jurisdiction within which they occurred. So-called 'outside' forces therefore had strong motives to come to the aid of assailed state-machineries. This made rebellions more difficult. On the other hand, the intrusion of the accumulators of capital, and hence of state-machineries, into the daily life of the work-forces was far more intensive in general under historical capitalism than under previous historical systems."

過往的反體制運動,無論是左翼的工人運動,還是右翼的民族運動,都脫離不了一個基本策略,就是奪取國家櫂力。然而, Wallerstein 認為這種策略不可能達到反體制的目的,而只會令後革命的國家再一次落入世界體系的資本主義分工上

"The key to the problem may in fact lie in the basic strategic decision to make the seizure of state power the pivot of the movement's activities. The strategy had two fundamental consequences. In the phase of mobilization, it pushed each movement towards entering into tactical alliances with groups that were in no way 'anti-systemic' in order to reach its strategic objective. These alliances modified the structure of the anti systemic movements themselves, even in the mobilization stage. Even more importantly, the strategy eventually succeeded in many cases. Many of the movements achieved partial or even total state power. These successful movements were then confronted with the realities of the limitations of state power within the capitalist world-economy. They found that they were constrained by the functioning of the interstate system to exercise their power in ways that muted the 'anti-systemic' objectives that were their raison d'etre."

「革命黨」奪取國家權力,在整個資本主義體系下,代表的是一場改革,而非革命︰

"This seems so obvious that one must then wonder why the movements based their strategy on such a seemingly self-defeating objective. The answer was quite simple: given the political structure of historical capitalism, they had little choice. There seemed to be no more promising alternative strategy. The seizure of state power at least promised to change the balance of power between contending groups somewhat. This is to say, the seizure of power represented a reform of the system. The reforms in fact did improve the situation, but always at the price of also strengthening the system."

又因為所謂的後革命國家無一倖免都跳不出歷史資本主義的體系之外,其結局往往就是重新啟動資本積累的引擊,繼續剝削工人,於是這些所謂革過命的國家,又會重新出現新的反體制運動︰

"...the so-called post-revolutionary regimes continue to function as part of the social division of labour of historical capitalism. They have thereby operated, willy-nilly, under the relentless pressures of the drive for the endless accumulation of capital. The political consequence internally has been the continued exploitation of the labour-force, if in a reduced and ameliorated form in many in stances. This has led to internal tensions paralleling those found in states that were not 'post-revolutionary', and this in turn has bred the emergence of new anti-systemic movements within these states."

對於國家在資本主義的意義,可以如此總結︰"Changes in state structures have altered the politics of accumulation; they have not yet been able to end them."

--

後半本的 "Historical Capitalism" ,主要處理兩個議題︰意識形態和歷史進步論,而我認為後者尤其重要。跟正統的馬克思主義者不同, Wallerstein 懷疑歷史進步論,他質疑進步論中的兩個觀點--(1)歷史資本主義比先前的歷史系統較為進步;(2)歷史資本主義終會被更進步的歷史系統(社會主義)所取代--這兩個觀點彼此相關、互相證成,而 Wallerstein 則透過攻擊觀點(1),解釋進步並非必然,繼而動搖我們對(2)的信仰--我們決不能只坐等資本主義滅亡,在歷史的交叉點上,我們的行動將會影響歷史的走向。

嫌太長的話可以按中文詮腳選段閱讀。

(四)種族主義

Wallerstein 認為前資本主義時代的恐外情緒跟現代的種族主義是不同的東西,種族主義是資本主義底下的意識形態,被用以合理化不平等的經濟分配。

"What we mean by racism has little to do with the xenophobia that existd in various prior historical systems. Xenophobia was literally fear of the 'stranger'. Racism within historical capitalism was the mode by which various segments of the work-force within the same economic structure were constrained to relate to each other. Racism was the ideological justification for the hierarchization of the work-force and its highly unequal distributions of reward." 
"The ideological statements have been in the form of allegations that genetic and/or long-lasting 'cultural' traits of various groups are the major cause of differential allocation to positions in the economic structures. However, the beliefs that certain groups were 'superior' to others in certain characteristics relevant to performance in the economic arena always came into being after, rather than before, the location of these groups in the work-force. Racism has always been post hoc. It has been asserted that those who have been economically and politically oppressed are culturally 'inferior'. If, for any reason, the locus in the economic hierarchy changed, the locus in the social hierarchy tended to follow."

種族主義除了有利規限受害者對階級流動的期待,也有利分化中層和底層的勞動軍,就像利用囚犯來監管囚犯。

"[Racism] has served to socialize groups into their own role in the economy... Racism, just like sexism, functioned as a self-suppressive ideology, fashioning expectations and limiting them." 
"[Racism] served to keep low-ranking groups in line, and utilize middle-ranking groups as the unpaid soldiers of the world police system. In this way, not only were the financial costs of the political structures reduced significantly, but the ability of anti-systemic groups to mobilize wide populations was rendered more difficult, since racism structurally set victims against victims."

(五)普世主義

Wallerstein 認為資本主義中的兩大意識形態︰種族主義和普世主義,看似互相矛盾,但其實都是依資本主義運作的需要在同一個系統下製造出來的。普世主義主要是菁英的信仰,有利於各國的上層及中層階級的整合。

"Work-forces could not be expected to perform efficiently and continuously unless they were managed by cadres. Cadres too have had to be created, socialized, reproduced. The primary ideology that operated to create, socialize, and reproduce them was not the ideology of racism. It was that of universalism."
"Whereas racism served as a mechanism of world-wide control of direct producers, universalism served to direct the activities of the bourgeoisie of other states and various middle strata world-wide into channels that would maximize the close integration of production processes and the smooth operation of the interstate system, thereby facilitating the accumulation of capital."
"Scientific culture... was a form of socialization of the diverse elements that were the cadres of all the institutional structures that were needed. As a language common to cadres but not directly to the labour-force, it became also a means of class cohesion for the upper stratum, limiting the prospects or extent of rebellious activity on the part of cadres who might be so tempted."

(六)歷史進步論

然後 Wallerstein 也討論了歷史進步論這個意識形態,他先指出左翼的歷史進步論合理化了社會主義,但同時也合理化了資本主義。而根據過往幾十年的經驗,比較蘇聯和美國的物質生活水平,唯物主義進步觀也可以反咬「社會主義實驗」一口,這成了當代左翼其中一個意識形態危機。

至於對進步論本身, Wallerstein 持否定的態度,指出它最大的問題在於 "the one-sidedness of all measures proposed" ,並逐一質疑進步論者提出的各種測量指標︰

1) 科學/科技進步 v.s. 被丟失遺忘的傳統知識

"...we never seriously discuss how much knowledge we have lost in the world-wide sweep of the ideology of universalism. Or if we do, we categorize such lost knowledge as mere (?) wisdom. Yet, at the simple technical levels of agricultural productivity and biological wholeness, we have been discovering of late that methods of human action discarded a century or two ago (a process enforced by enlightened elites upon backward masses) often need to be revived because they turn out to be more, not less, efficacious."
2) 生產效率進步 v.s. 工作負擔增加
"Each input of human energy has been rewarded with steadily greater outputs of products, which is surely true as well. But we do not calculate to what degree this has meant that humanity has reduced or increased the total inputs of energy that individuals separately, or all people within the capitalist world-economy collectively, have been called upon to invest, whether per unit of time or per lifetime. Can we be so sure that the world is less burdensome under historical capitalism than under prior systems?"
3) 物質生活提升 v.s 精神生活墜落
"...doubts in this domain have grown steadily throughout the twentieth century, as our now frequent references to 'quality of life' and mounting concern with anomie, alienation, and psychic maladies indicate."
4) 對人類更安全的環境 v.s. 現代戰爭與核威脅
"Once again this is incontestable at a micro level... But has this really been true at a macro level, even up to now, and even omitting the Damoclean sword of nuclear war?"

Wallerstein 更指出,要說今日的世界對比一千年前有更多的自由、平等和友愛,也至少不是不證自明的。但不要搞錯,他並沒有把前現代的生活想像成田園牧歌,它們也是沒有多少自由平等友愛,但問題是在比較之下資本主義世界真的比以前多嗎?還有一個說法就是殘忍行為(Cruelties)的減少, Wallerstein 回應說,即使不考慮歷史上資本主義對窮人的殘酷,二十世紀的歷史也足以顯示今人的 "unusual talents of refinement in these ancient arts."

提出了對進步論的種種質疑後,Wallerstein 打算要為一種少有的說法辯護︰"the absolute (not relative) immiseration of the proletariat" ,今日的資本主義比二百年前的更差,生活相對改善了的工人只是世界人口的一小部份。

"Surely you can't be serious; surely you mean relative immiseration? Is not the industrial worker strikingly better off today than in 1800? The industrial worker, yes, or at least many industrial workers. But industrial workers still comprise a relatively small part of the world's population. 
The overwhelming proportion of the world's work-forces, who lives in rural zones or move between them and urban slums, are worse off than their ancestors five hundred years ago."
"They unquestionably work harder -- more hours per day, per year, per lifetime. And since they do this for less total reward, the rate of exploitation has escalated very sharply."
他也提到資本主義對社區的破壞,小型的社區結構被大型的政治經濟結構取代,名義上的個人主義和自由主義並沒有為鄉區的窮人帶來「解放」,而是更多的操控和壓迫。
"In many areas, and for long periods, the prior role of the community structures has been assumed by 'plantations', that is, by the oppressive control of large-scale politico-economic structures controlled by 'entrepreneurs'. The 'plantations' of the capitalist world-economy -- whether based on slavery, imprisonment, share-cropping (forced or contractual), or wage-labour -- can scarcely be said to have provide more leeway for 'individuality'." 
"Even where one form or another of direct authoritarian control of agricultural activity (what we have just labelled 'plantations') was not substituted for the prior laxer community structure of control, the disintegration of the community structures in rural zones was not experienced as a 'liberation', since it was inevitably accompanied, indeed frequently directly caused, by a constantly growing control by the emergent state structures which increasingly have been unwilling to leave the direct producer to his autonomous, local decision-making processes."
那為什麼活在城市的我們很容易覺得「世界在變好」?那是因為我們都是受惠於資本主義的中層成員︰

"A good deal of the 'progressive' politics of the past several hundred years of historical capitalism has resulted in the steady diminution of the unequal distribution of the world surplus-value among that small group who have shared in it. The shouts of triumph of this 'middle' sector over the reduction of their gap with the upper one per cent have masked the realities of the growing gap between them and the other eighty-five per cent."

(七)革命的問題

進步論的另一個原素,就是認為在歷史的演化當中,一個新的階級會取代一個舊的階級,而正如上回都指出過, Wallerstein 認為正確的歷史圖像是封建時代的貴族地主階級將自己轉化為布爾喬亞(bourgeoisie),這個轉化是為了維持及擴大他們剝削勞動力的能力。

馬克思主義者對「無產階級革命」的想像一直都是建基於歷史上的「布爾喬亞革命」,但由於「布爾喬亞革命」並不是一個階級推倒另一個階級的革命,馬克思主義者的基本戰略就大有問題了。

更重要的是, Wallerstein 雖然同意資本主義會因其內在矛盾而最終解體,但他提醒我們資本主義的滅亡不一定會帶來社會主義,我們的資產階級可能會透過轉化自身來發展出另一種更有效的階級社會(class society)︰

"Progress is not inevitable. We are struggling for it. And the form the struggle is taking is not that of socialism versus capitalism, but that of a transition to a relatively classless society versus a transition to some new class-based mode of production (different from historical capitalism but not necessarily better).
"The choice for the world bourgeoisie is not between maintaining historical capitalism and suicide. It is between on the one hand a 'conservative' stance, which would result in the continued disintegration of the system and its resultant transformation into an uncertain but probably more egalitarian world order; and, on the other hand, a bold attempt to seize control of the process of transition, in which the bourgeoisie itself would assume 'socialist' clothing, and seek to create thereby an alternative historical system which would leave intact the process of exploitation of the world's work-force, to the benefit of a minority."

這一點尤其重要︰一個新的階級社會可以以「社會主義」的裝扮登場,繼續服務於同一批統治階級,抗爭者決不可以因為資本主義被取代就急於慶祝。

在這一節的最後, Wallerstein 提醒我們無論在分析評價各種反體制運動時,不要忘記這些運動,包括「社會主義國家」,都並非外在於歷史資本主義,它們的存在本身就是歷史資本主義的矛盾展現,他們的負面影響應該歸咎於資本主義,而不是一個尚未存在過的社會主義;「社會主義國家」對工人的剝削,也應該歸咎於他們處於世界資本主義分工的邊陲位置,而跟他們是由共產黨還是親資政黨領導,關係較小。

"The first and most important thing to remember in any such assessment is that the world socialist movement, indeed all forms of anti-systemic movements, as well as all revolutionary and/or socialist states, have themselves been integral products of historical capitalism. They were not structures external to the historical system but the excretion of processes internal to it. Hence they have reflected all the contradictions and constraints of the system. They could not and cannot do otherwise.
"Their faults, their limitations, their negative effects are part of the balance-sheet of historical capitalism, not of a hypothetical historical system, of a socialist world-order, that does not yet exist. The intensity of the exploitation of labour in revolutionary and/or socialist states, the denial of political freedoms, the persistence of sexism and racism all have to do far more with the fact that these states continue to be located in peripheral and semi-peripheral zones of the capitalist world-system."
"They can only be sensibly evaluated by asking how much they have contributed to the world-wide struggle to ensure that the transition from capitalism is towards an egalitarian socialist world-order."

(八)資本主義的矛盾與終結


本書的最後一部份-- "Future Prospects" --繼續闡述資本主義的內在矛盾,並嘗試勾劃這個歷史系統的未來。

針對資本主義的內在矛盾, Wallerstein 的分析跟傳統馬克思主義大同小異︰在企業的彼此競爭之下,企業要維持利潤率,就必須降低勞動力成本。但如果降低工人薪資,又會導致市場的消費力減弱,總需求下降。這就是資本主義的內在矛盾之一。 Wallerstein 認為,這矛盾在歷史上的解決方式,是透過地域區隔(geographical disjuncture)來達成的。任何時候,世界體系中受特別思典的地區採取了提升總需求的政治措施(例如定立最低工資、提高福利等),在世界體系的邊陲地區就會同時增加一堆新的廉價勞動力。可以是將更多效區農民轉化為城市工廠工人,也可以是將整個世界資本主義體系擴展到之前所未包括的地方,例如一些自給自足的郊區經濟體。也就是說,企業透過尋找未開拓的地區,將其轉化為廉價勞動力市場,從而降低了生產成本,而又同時能維持到本國消費市場的總需求。

而 Wallerstein 認為,這種策略有其極限︰未被世界
資本主義體系編入的地區有限,而且在不斷縮小。實際上,在八十年代,這個極限已經碰頂,資本家再沒有更廉價的勞動力可供開發,在利潤率下跌的情況下,資本家和國家合力向本國人民開刀︰把國有資產私有化,撤銷本國的福利政策,並透過信貸擴張之類手段維持總需求。 Wallerstein 認為廿一世紀將會見證資本主義的矛盾走到極限,進入系統性危機,政治將變得非常不穩定,並有機會向任何一個方向前進。

這個系統性危機將會以什麼方式呈現呢? Wallerstein 認為其中一個可能,就是來自第三世界的新移民跟核心國家的社會發生「內戰」

"...the massive, relentless drive of households to migrate illegally to wealthier climes, to escape from the South to the North. [...] Over the coming twenty-five years, we may expect enormous numbers to succeed in this South-North migration. The double reality of the material conditions gap and the demographic gap makes it highly improbable that any state policy in the North can be seriously effective in stemming the flow."
"The phenomenon of the 'Third World within' in the core zones of the capitalist world-economy will become massive as the demographic balance shifts. "
"The demographic transformation, caused by weakening state structures, will in turn weaken them further. Social disorder will once again become normal in the core zones. In the last twenty years there has been much discussion on this under the false label of increased crime. What we shall be seeing is increased civil warfare. This is the face of the time of troubles. The scramble for protection has already begun. The states cannot provide it. For one thing they do not have the money; for another they do not have the legitimation. We shall see instead the expansion of private protection armies and police structures, by local communities, by religious bodies, and of course by crime syndicates."

(九)資本主義後的未來

這種情況下,歷史將何去何從? Wallerstein 認為我們頂多可以粗略勾勒出未來的幾種可能性,至於當中的細節,則無從預測。他勾勒了三種可能走向︰

A, 新封建主義

One is a sort of neo-feudalism that would reproduce in a far more equilibrated form the developments of the time of troubles --- a world of parcellized sovereignties, of considerably more autarkic regions, of local hierarchies. This might be made compatible with maintaining (but probably not furthering) the current relatively high level of technology. Endless accumulation of capital could no longer function as the mainspring of such a system, but it would certainly be an inegalitarian system. What would legitimate it? Perhaps a return to a belief in natural hierarchies.
B. 民主法西斯主義
A second formula might be a sort of democratic fascism. Such a formula would involve a caste-like division of the world into two strata, the top one incorporating perhaps a fifth of the world's population. Within this stratum, there could be a high degree of egalitarian distribution. On the basis of such a community of interests within such a large group, they might have the strength to keep the other 80 per cent in the position of a totally disarmed working proletariat.
C. 社會主義
A third formula might be a still more radical worldwide highly decentralized, highly egalitarian world order. [...] The increased political sophistication and technological expertise we now have makes it doable, but not at all certain. It would require accepting certain real limitations in consumption expenditures. But it does not mean merely a socialization of poverty, for then it would be politically impossible to realize.
最後, Wallerstein 提醒我們,歷史還有很多可能,最重要的是我們認清這些可能都存在,而歷史的選擇將會取決於我們未來五十年的集體努力。

新一年,踢走 smart-ass 建築


新年流流,朋友 send 來一篇批評當代建築的好文章(New year's resolutions for architects in 2015),文中記載的其中一件事,就是最近 Zaha Hadid 設計的東京奧運體育場,遭到日本建築師聯合反對,32,000 人聯署要求撤消她的設計,她卻回應說這些當地人只是妒忌她贏出了比賽,指責他們偽善。這件事實在太有象徵意義,我在此也想跟大家分享看法,希望在 2015 年城市人可以重新獲得他們應有的 public space 。

除了些少 David Harvey ,我沒讀過多少建築理論和城市規劃,或許不應在這個題目上發言太多,不過有時有些說話就是要外行人才能講。早兩個禮拜前我才去了金澤 21 世紀美術館,參觀了兩個展覽,一個講日本自戰後到當代的建築發展,另一個講 3.11 大海嘯以來的最新發展。兩個展覽都不約而同地指向同一個思想︰反思現代主義,重拾建築與環境和居民的聯繫。 3.11 大海嘯的發生,迫使了很多日本建築師思考自身專業的意義︰在這種時刻,建築能為社會貢獻什麼?於是有建築師為災區設計了很多簡易搭建的臨時居所,更考慮了如何在空間的設計上同時保障災民的私隱,又鼓勵守望相助的小社區生活。 3.11 之後,更多的日本建築師開始放下自己的身段,走入社區跟居民學習,聆聽他們的聲音,了解他們的困難。更有建築師跟居民組織會議,跟幾十個居民一同討論,建築師在每次會議後會根據居民的意見更改設計,然後再把設計圖呈上會議繼續討論,這樣來來回回,要舉行十幾次,甚至幾十次會議才能最終拍板。私有化的信徒大概又要嚷著說什麼效率不彰,但這樣的民主參與過程本身不也是目的嗎?城市空間的發展是以數十年,甚至以過百年的影響為尺度,難道不值得我們慢慢來嗎? 3.11 之後的日本人,已經懂得反省高速發展的迷思︰發展利及了什麼人?又奪取了什麼人的城市景觀和公共空間?一場大災難讓人看到真正重要的,不是一下就會被摧毀的石屎玻璃,而是人與人的關係。在這個思潮底下,怪不得日本建築師會群起反對 Zaha Hadid 那種不顧社區脈絡的空降怪物。而她只是贏了比賽就傲慢地鄙視當地人的反對聲音,也正好突顯了當代建築界的體制性問題︰這是一個以大型資本和極度個人主義的設計比賽為中心的世界,居民的利益,民主的精神通通都不在主流建築師的意識之中。

有說藝術不能搞民主,聽一大堆外行人的意見,還哪有可能創新?其實我本人也是熱愛著現代主義的,我不在品味原則上反對奇型怪狀的玻璃樓,但現代主義的最核心精神是對藝術媒介自身的反省,對藝術家角色身份的反思︰藝術是為了什麼?在客觀的層面上,藝術家服務了誰的利益?是大資本家的利益,還是大眾的利益?當我代替發展商把越來越多的公共空間收編為嚴密監管的「私有-公共空間」(private-public space)時,我認為我是在藝術上創新,但客觀的層面上我是誰的僕人?當我將大樓分開兩個入口,有錢人用豪華的前門,工人則要用寒酸的後門時,我這個設計者的腦袋是在想什麼?(這些問題上述的文章都有提及)

相對於傳統認為知識份子外在於社會,並能高高在上的引領社會發展的想像,左翼思想家 Antonio Gramsci 提出了「有機知識份子」(organic intellectual)的概念,他首先指出傳統的知識份子以專業為名,往往卻是以教育機構和媒體為手段去代替統治階級操控群眾;而「有機知識份子」則是他提倡的新身份,他指出大眾並非缺乏對其生活經驗的掌握,而只是未必具有把這些經驗充分表達出來的能力,有機知識份子的責任就是游走於普羅大眾之間,跟他們學習,並協助他們清晰表達出自己的經驗。到頭來,誰會比居民自己更清楚日常生活中的需要和不便呢?與其空降,想當然爾地認為自己比居民更了解他們需要什麼,倒不如好好跟他們學習,然後協助他們構想出點子,設計出一個真正屬於他們的空間。

或許現代主義的那種讓個性和想像力奔馳的機會很難叫人割捨,但現代主義決不只是形式創新而已,形式的創新只是對形式的反思的一個表現,真正重要的不是形式,而是批判意識,把自己放在更大的脈絡之中思考。建築不是單純放在白箱子(white cube)的東西,影響的是整個城市,而整個建築界的運作,又要比任何藝術媒介都要受資本操控。當你以為自己是個反叛的藝術家時,你其實也只是在替資本家賺錢而已,個人主義是一種幻覺。真正的反抗,是爭取開放大眾的參與,協助市民重奪規劃城市的權力,反對一少撮人為了一少撮人的利益而把我們的家當成 Sim City 。這才是真正的反叛,真正的批判。

佔領運動的左翼反思

Image: AP PHOTO/ASSOCIATED PRESS
意識形態的定義︰
Emile Durkheim: 'the use of notions to govern the collation of facts rather than deriving notions from them.'
佔領運動開始以來就看見不少(堅持馬列主義正統的)左翼急著以自己常用的理論框架來為佔領運動「定性」,我認為要提醒的一件事,就是我們應先從事實出發,再達至結論,也不要只選擇專注於某些事實而忽略了另一些。一個問題︰

佔領運動的主體是誰?

有些人說運動的主體是親美資產階級,因為整場運動就是由親美右傾媒體在兩年前開始不斷煽風點火的,沒有這些資金,泛民的運動也不可能發酵。但問題是,香港根本不缺親中媒體,如果這群年青人是受親美媒體煽動,為何他們不選擇受親中媒體煽動?這種化約主義讓我們看不清楚媒體和受眾間的複雜互動,媒體可以影響受眾,但受眾也可選擇媒體。

另一些人則說這場運動是中產階級運動,但我在各佔領區都留意到有很多工人的參與,特別是在旺角。當然「反佔中」的群體裡面有很多都是工人,但也不能無視當中也有很多中產階級(如喜記老闆和周融)。雖然階級視野還是很重要,但在廿一世紀,在香港,階級不是鐵板一塊的東西,除了階級之外還有身份認同、職業類型和意識形態,都會左右人們的政治取態。(女性主義運動的主體一向都是中產階級婦女,這是否代表女性主義運動的成果就一定跟工人階級女性的利益不相容?)如果說的是這場運動所要爭取的階級利益,我也看不見工人利益如何會因公民提名和廢除功能組別而受損。正好相反,在目前的議會僵局下很多有利勞工的法例都無法通過,擴大目前議會的代表性確實能提升這些法例通過的機會。要令工人有經濟和精力條件參與政治,提高其階級意識,爭取一些階段性的勞工保障政策是必要的,這也是為了舒緩工人當下的經濟困難,不能說止痛藥無法把病根除,就可以任由病人痛苦下去的。

又有另一種說法認為佔領運動的主體是反中反華、鼓吹排外的本土派,我很懷疑持這種想法的人有沒有到過現場觀察。無錯,確實有一部份年青參與者對大陸人懷有恨意,但他們的排外議程有否騎劫運動本身的議程?他們又佔了運動主體中的多大比例呢?是否落實了雙普選,本土派就能通過所有的排外議案呢?

我看到的是,這場運動中有從左至右各式各樣的人,而且不斷地改變形態,不能簡簡單單地把它套入某個試圖解釋一切的理論框架,把一切跟理論不容的異例恣意地視為「少數例外」或「泛民的假面具」,大洌洌地展示自己的 confirmation bias 。想抓住一個現實,往往要由很多不同的理論角度切入。不要以為政治學史上只有一派人掌握了全部真理,其他思想家都是弱智,他們的理論沒有任何反映真實的成份。持有這種態度的人,只是懶惰而已。

冷戰後的左翼該如何做?

當我們很信仰某種最終的救贖,我們就會對走向救贖途中的苦難麻木起來。所以基督教可以對現世的不公義漠不關心,因為主的國終會降臨;所以為了共產主義理想的實現,蘇聯和中共的工程師可以不顧他們對人民造成的「短期」苦難。意識形態的可怕之處就在於它把理念置於現實之上,把大歷史置於小個體之上。現實不會是 all or nothing ,不能說某某行動並不能解決根本問題就不幹。正如我們需要持續批判慈善工業的偽善,但叫人全部停止捐款只會造成更大的即時災難。我們要有長遠的目標,去改變一些結構性的東西,但也要有即時的行動,去舒緩正在發生中的苦難。爭取到普選之後政府和議會是否會減少向商界的傾斜,退休保障和有關勞工權利的法例能否通過,還是未知之數,但這是目前唯一可見能夠有效大大提高希望的措施,總好過維持於現狀(而這個現狀就是左翼運動持續低落了幾十年的現狀)。

幸福就是相信幸福



先前在 Existential Comics 看了一篇探討何謂幸福的漫畫,覺得頗有深度,所以想撰文為他的論點再作一些延伸討論。

幸福是一種判斷


漫畫作者透過兩個人物的對話來帶出討論,其中一個人說所謂幸福就是 serotonin 和 dopamine ,是來自一些腦內的化學物,產生出快樂的感覺。另一個人反駁說,幸福絕不只是一種感覺而已,他提出了一個思想實驗,假想一個瘋狂科學家把你縛在椅子上,他能透過控制你腦內的化學物分泌來為你製造出最愉悅的感覺,但同時他在你面前把你的家人一個個地殺掉,這樣的情況下,你會說你幸福嗎?

當然不會!這就說明幸福不只是一種內在於我們的感覺而已,它跟我們身處的環境,以及我們對環境的詮釋有關。作者繼續舉出拿破倫以及歷史上眾多堅韌的科學家作例,指出很多超凡的偉人,都不會因自己要面對的艱辛而厭惡人生。生理上的歡悅既不是幸福的充分條件,也非其必要條件。

其實這個說法其實在心理學也可以找到它的對應,two-factor theory of emotion 就認為生理喚起(physiological arousal)要經過主體的詮釋才會成為一種情感(emotion)。這個理論跟著名的吊橋現象有關,在實驗中,心理學家讓男性受試者橫過一條吊橋,到了對岸會有一個漂亮的女實驗員派發問卷和她自己的電話號碼,讓之後對實驗有什麼疑問的受試者查詢。而控制組的受試者則不需要橫過吊橋,而是直接領取問卷和電話號碼。實驗結果發現吊橋組比控制組有更多受試者打電話給女實驗員,希望能跟她約會。這個差異很可能就是來自吊橋組的受試者錯誤地把吊橋引起的緊張感詮釋成對女實驗員的心動感覺,而他們卻完全意識不到吊橋對他們的行為有什麼影響。在這個例子中,橫過吊橋會引起受試者的一些生理喚起,例如心跳加速、冒汗、睪丸素水平提升,但受試者還需要透過他對環境的認知來尋找這些生理喚起的原因,從而詮釋出這是驚恐還是愛。

幸福這回事也很相似,它不是一種客觀的性質,而是一種判斷。判斷是由價值觀、我們對環境和自我的認知、以及我們對環境和自我的詮釋所構成的。所以家人在面前被屠殺時,縱使我的腦被注入很多 dopamine ,我還是絕不會判斷這是幸福,因為我清楚認識到家人被殺以及自己的腦內分泌受操控的事實,我也很清楚這兩個事實對我來講的意義(家人對自己的重大意義;人工製造、自我中心的愉悅感的零意義),還有我有一套價值觀,拒絕接受這種被強加的快樂。

所以,作者借角色之口作出結論︰ "Happiness is believing you are happy" 。由於幸福是一種判斷,這種判斷必定需要根據以上所講的關於事實和價值的信念(belief)作基礎。如果瘋狂科學家告訴我,家人被殺的畫面只是一個幻覺,而我又相信他,那我所受的精神困擾也會減輕很多。又,如果我信奉絕對的利己主義,認定人生的唯一目的就是快樂,那我就可能會覺得家人之死不值得讓我精神受困,倒不如好好享受科學家提供的極致歡悅。隨著人的成長,信念、認知和價值觀有所改變,我們也可能會發現以前認定為幸福的事其實很愚蠢,例如實屬虛榮幻象的名聲。所以,幸福並無其他客觀標準。一些人可以為國家為理想遭受極大的客觀痛苦卻堅持自己是幸福的,而另一些人可以在狂歡的同時感到空虛寂寞,生命了無意義;這些差異都是跟不同人的不同信念,或同一個人在不同時空下的不同信念有關。

自欺與絕望


這個年頭講「信念」,很容易就會聯想起一種「正能量」式的自欺欺人--我只要把自己所面對的所有事都詮釋成好事,或者把所有問題都塞進床底下,那不就沒有煩惱了嗎?這不是不行,但卻有一種危險︰當事情演變到我們無法不作正視的時候,我們就已經無可能挽回了。對 Leo Tolstoy 來說,迫使我們誠實地反思人生的最後一道王牌,就是死亡。他的短篇 The Death of Ivan Illyich 談的就是一個典型的公務員 Ivan ,他以追隨上流社會的生活風尚來引導自己的人生,所以他跟所有人一樣,娶了一個體面的老婆,生了幾個小孩。但有家庭就注定有麻煩,他不想因為家庭而失去他的心境安寧,所以他的解決之道就是借工作為藉口逃避家人。妻子和孩子們抱怨愈多,他對工作就愈投入。這種對工作的投入,也為他贏來他想要的財富和地位,他對一切都非常滿意,人生沒有比這樣更好了。可是,一天他發現了自己患上了不明之症,他的身體告訴他將命不久已,他開始對死亡的未知惶恐起來,卻發現身邊沒有任何人願意分擔他的焦慮。 Ivan 在面對死亡的這幾個月內感到無比孤獨,家人對他因痛苦而發的嚎哭也漸漸變得習以為常, 沒有人願意真的投入到一個瀕死者的內心,更多人為了維持日常生活運轉而假裝他沒有事,職場上認識的人把工作看得重,都不會關心他,而家人的關係本身已很疏離,現在更成了他們的負擔。比起肉體上的痛苦,精神上的痛苦更讓他崩潰。 Ivan 於是被迫思考,究竟是什麼出了錯,讓他那個愜意的人生,會以如此孤獨不安的方式結束?他拼命地回憶,想要搞清楚,而直接臨終的那一天,他才醒悟︰「啊,那種所謂上流社會的生活風尚,會不會其實是錯誤的?」那些表面幸福的在上位者,會不會也是在臨死前才被迫償還借來的快活,才發現自己的錯誤,但那時已經沒有一個人可以傾訴?就在這瀕死的一刻, Ivan 的信念全數被推翻,他發現自己的整個人生都是一場錯誤,但他已經沒有改正的機會了,於是他只好在絕望與孤獨之中死去。

自欺欺人和鴕鳥政策的代價,就是臨終的絕望。

The Death of Ivan Illyich 這則寓言,不能僅當作是 Tolstoy 對上流社會的批判。習染上流社會的市儈俗氣,固然是 Ivan 最後要面對如此強烈的虛無感的原因之一,但即使假設 Ivan 是一個有理想熱血的人,追逐的不是上流社會,而是以傑出運動員為榜樣,一生在體育界上攀爬,會否也有一日因為疾病或其他原因,而後悔他為理想犧牲了跟家人和朋友相處的時間?會不會後悔他所放棄了的青春?又如果他能做到面面俱圓,會不會也有可能最終後悔自己一生平庸,沒有發揮自己的極限?我們總會覺得「不會的,我對自己的生活方式很有信心,我不會後悔的」,但這有可能中了一個認知偏差(cognitive bias)的陷阱︰我們總會高估了自己性情和思想的 constancy ,例如我們會覺得十年後的自己跟現在不會差異很大,但當去回想十年前的自己是如何時,又發現十年間自己變化很大。這就是我們的存在困境︰幸福建立於信念之上,而信念又很容易被推翻。除了我們的性情和價值觀會因時間改變而推翻先前的信念,一些 life events ,例如疾病、死亡、中年危機或原有的生活慣性因突如其來的改變(產子、離婚、失業、家人逝世等)而被打亂,也會令我們不得不反思人生,重新尋找意義。困難就在於,我們很難預測到怎樣才是一個無悔的人生。

自由的代價


存在主義哲學家 Søren Kierkegaard 會說︰無論你如何選擇自己的人生,你也會後悔。一位朋友因不知道應否跟一個女子結婚,於是寫信向 Kierkegaard 請求意見(他真是問對人了), Kierkegaard 如此回應︰
I see it all perfectly; there are two possible situations — one can either do this or that. My honest opinion and my friendly advice is this: do it or do not do it — you will regret both. [1] 
無論你做還是不做,你都會後悔。如果你為了理想而犧牲家庭,當你年老患病最需要家人時卻無法再彌補跟子女的情感疏落,你就會後侮;如果你為了家庭而犧牲理想,當你人生已過一大半時,你又會不甘自己的平庸,你會厭惡不斷重複的日常,你會變得忌恨年青人,你會後悔沒有貫徹理想。 Kierkegaard 說,所謂的畏懼(dread),就是意識到自己有可能亦有自由去進行選擇。正因為我們有自由去選擇自己要追逐理想與否,我們就要對其後果負上責任。意識到自己要為每一個決定負責,這種負擔能使人窒息,遲遲不敢作決定。

我們對自己的信念感到不確定,這個不確定性除了是外在的(我們所不能操控的際遇和運氣),也是內在的,即我們意識到在我們選擇的信念之外,有無限多的其他可能,我們無法避免懷疑自己的選擇是否較好的。所以,要幸福的話,只有信念是不夠的,我們還要把信念轉化為信仰。我們可以把「信仰」(faith)定義為「可能性的持續廢除(continuous annullation of possibilities)」。認定一個人生信仰,例如我要當一個運動員,就要持續地去廢除其他存在的可能性︰我有做個工資可觀的白領的可能;我有成為體育老師,換取安穩生活的可能;我有放棄自己本來的計劃,跟隨被調職的丈夫到外國生活的可能。把一種偶然之下獲取的想法,一種在某個時刻機緣巧合下產生的熱情,一種受成長環境灌輸的價值觀,認定為是必然的,不可更改的,必須服從的人生志業,這就是信仰。所以,宗教是一種信仰,如果我不是生長於基督教家庭而是生長於伊斯蘭教家庭,我就不會信奉基督教,但我既然已經信奉基督教,我要不被這種信念的任意性(arbitrariness)所動搖,我就要把這種偶然認定為必然,把信念化為信仰。[2]愛情也是一種信仰,所謂愛情就是把一個偶然遇到,實際上並非唯一的對象視為唯一。如果我們不持續廢除「我這個伴偶隨時可以由其他人代替」的可能性,我們就無法專一,無法維持任何長久關係。[3]其他的事上,如事業的決定、政治上的抉擇、道德上的選擇,都或多或少依循這個邏輯︰如果我們時刻不忘自己的政治取態在很大程度上是由階級背景、自己所接觸的有限資訊以及種種偶然因素所產生的偏見,那我們就很難在政治上有任何行動。[4]

 Fyodor Dostoevsky 所著的 Notes from Underground 正正是描寫這樣的一個人物,他經常懷疑自己,生怕被自己的大腦所騙,他無法形成任何持久的信念,更不用說有任何信仰,他認為那些能在生活中很主動(active)的人,都是因為不夠清醒(less conscious)和不夠聰明(less intelligent),那些人正是因為不知道如何批判自己、分析自己,才會那麼幼稚地把很多事情視為理所當然。但如此高傲的他卻因自己的懷疑主義而無法投入生活,常為自己失敗的人生感到羞恥。 Dostoevsky 寫這本書的其中一個目的,就是要批判理性主義對傳統信仰的侵蝕,如果每一種實踐(practice)都要求一個理性的辯護(rational justification),那我們最終會發現每一個辯護理由都有合理化(rationalisation)的可疑[5],於是會喪失任何行動的起點,循入虛無主義。傳統和宗教的社會功能就在於給予個人一個既定角色和意義網絡,例如作為新教徒,我的存在意義就是以辛勤的工作來榮耀上帝,無論如何我也不去審問這個教條的基礎,我就能安心地以這個標準來判斷自己的人生成功與否,而不需要因對標準本身產生懷疑而懷疑自己的幸福。有了信仰,我就起碼能有一條通往幸福的路線圖,接下來就是努力向著一個特定終點前進,不為其他可能終點而分心。

可是,正如 Jean-Paul Sartre 指出,接受什麼宗教信仰的指引,歸根究底都是個人自由的選擇,我們無法把責任推卸給教會、家庭或政黨,所以還是要回到那個核心問題︰我們應該如何作出選擇?其實人生信仰的選擇根本沒有理性基礎可言,我們無論怎樣思考都無法有一個確鑿的答案,固此也沒有什麼根據可以讓我們肯定的說「這就幸福。」最普遍的對策是,乾脆假裝幸福不是一種判斷,而是一種感覺︰既然一切都不確定,既然一切都轉眼即逝,既然幹什麼都會後悔,那為什麼不把握當下的快樂,聽任情緒的指揮呢?--諸君,繞了一大個圈,我們還是回到了我們當代的時代精神。

科學光環與科學現實

Albert Einstein in 1921 (Source)


當年讀完廣義相對論(General Relativity)發現竟然沒有一個預測是可以嚴謹地從 Einstein field equations 中直接導出,頓時變得好失望。水星的近日點(perihelion)預測就是其中一個例子,除了需要用一個非常脫離現實的 Schwarzchild solution 去 approximate 之餘,竟然還要用 Newtonian mechanics,ad hoc 的程度非常嚴重[1],理論物理學從此就失去了在我小時候從《時間簡史》
中獲得的完美光環。這倒也不是理論物理的錯,只是我希望越大失望越大而已。不過,這一點就是我經常想跟外人解釋的一件事︰不要依賴科普知識去評價科學的成就,有時所謂預測準確至幾多個 significant figures,可能是 ad hoc approximation 的結果[2],而不是理論原型一出來就這麼準確。和 classical physics 不同,modern physics 中理論與證據之間的邏輯關係,比很多人想像的要稀薄。所以,雖然科學仍是我們最好的知識獲得途徑,但不要把她想得太理想,要真的把握當中的細節和計算才能下一個恰當的評估。

我引一段 
Paul Feyerabend 的講法︰


Ad hoc approximations abound in modern mathematical physics. They play a very important part in the quantum theory of fields and they are an essential ingredient of the correspondence principle [...] ad hoc approximations conceal, and even eliminate, qualitative difficulties. They create a false impression of the excellence of our science. It follows that a philosopher who wants to study the adequacy of science as a picture of the world, or who wants to build up a realistic scientific methodology, must look at modern science with special care. [3]

Feyerabend 的 proposal 很激進[4],放在神棍特別多的廿一世紀並不合時宜,但他的分析確實有很多有見地的地方︰



Modern science has developed mathematical structures which exceed anything that has existed so far in coherence, generality and empirical success. But in order to achieve this miracle all the existing troubles had to be pushed into the relation between theory and fact, and had to be concealed, by ad hoc hypotheses, ad hoc approximations and other procedures.

Feyerabend 舉的例子是 von Neumann 的公理化量子力學,指出公理化量子力學雖然比之前的版本在邏輯上較嚴謹,但代價卻是在計算實際問題時需要動用更多 ad hoc procedure ,例如要任意地修改一些物理定律,以求得到想要的計算結果,甚至需要承認它無法解決一些非常普通的問題如 scattering problem 。


這一個批判也動搖了所謂「數學是宇宙的語言」的流行講法,現實似乎是我們強行迫令具體執行遷就我們的抽象框架,把邏輯上不太說得通的東西都收藏在細節上,使得世界好像完美地跟數學模型重疊。(有一段時間我都非常驚訝,為什麼 Hilbert Space 這種完全獨立地發明出來的數學框架,能完美地套用到量子力學上呢?)如果我們仔細地觀察,就能看出數學與數學應用之間的關係並不直接,然後所謂 "the unreasonable effectiveness of mathematics" 的迷思,也就沒有那麼神秘了。




後記︰

這篇文章其實不是想叫讀者不要看科普書,而是想講透過科普書我們很容易會獲得一種 idealised picture ,從而可能會產生一種過份美化的科學觀。科普書還是很值得讀的,只是要比較小心。(另外,科普書中的科學史也很有誤導性,因為很多時身為科學家的作者都沒有受過史學訓練,寫出來的科學史通常都是一種 Whig history ,這我也是要透過讀科學哲學才能認識到的錯誤)


我受純數的訓練較多,這也可能令我對物理學的 rigor 有較高(審美)要求的原因,我的一些純物理的同學對 ad hoc assumption 就沒有那麼敏感。(習慣哲學思維可能也有關)


--

[1]這一點要 elaborate 一下,我直接用英文比較容易︰The so-called Schwarzchild solution of Einstein's equation is based on a simplified model in which the universe is centrally symmetrical, containing a singularity at the middle and nothing else. This is far from the case with our solar system. If we say the empirical evidences must correspond to the picture as described by GR for GR to be scientifically verified, problems arise as there is never a direct correspondence between the theory of GR and the evidences for it. Their relation is always mediated by various simplification, axillary assumption and ad hoc modification. (One can even say, these procedures constitute a cluster of secondary, ad hoc theories designed specifically for specific evidence to correspond to.) There is no such thing as an universal procedure which brings one from theory to facts or the other way round. Whether the theory per se entails the observable result, or the theory is forced to give the desired result, it is hard to say. Furthermore, Newtonian mechanics is supposed to be "reduced" from GR, but the fact is it is often necessary to presuppose Newtonian mechanics for many actual calculations to be carried out. The idea of increasing generality is thus (once again) shaken.

另外 Feyerabend 自己的解釋也可以貼出來以供參考︰ "[In the case of approximating the perihelion of Mercury,] making the required approximations would mean calculating the full n-body problem relativistically (including long-term resonances between different planetary orbits), omitting magnitudes smaller than the precision of observation reached, and showing that the theory thus curtailed coincides with classical celestial mechanics as corrected by Schwarzschild. This procedure has not been used by anyone simply because the relativistic n-body problem has as yet withstood solution. When the argument started, there were not even approximate solutions for important problems such as, for example, the problem of stability (one of the first great stumbling blocks for Newton's theory). The classical part of the explanations, therefore, did not occur just for convenience, it was absolutely necessary. And the approximations made were not a result of relativistic calculations, they were introduced in order to make relativity fit the case. One may properly call them ad hoc approximations."

當然,這是用一個 rationalism 的標準去看物理學的結果,而其實 Feyerabend 也不是要指責物理學家的邏輯令人失望,而是要說明 rationalist 理想中的 argumentation 並不是放諸四海皆有效的。


[2]關於 ad hoc hypothesis 可看 Wiki


[3]Feyerabend, Against Method, part 5

[4]我的看法是他的分析跟他的 proposal(revival of ancient myths, etc)可以分開考慮,理論上我是認同 methodological pluralism 的,但我認為他對研究資金這回事看得太樂觀,如果隨便什麼新舊理論都可以拿到資金研究,那大學早就破產了。而且科學測量的精確度要得以改進,也需要有 Kuhn 所講的常態科學(normal science)那個階段,這可以當作是權宜之道,但不能簡單視為「霸權」的。

自殺

(原發表於 2014 年 8 月 12 日,本人 facebook)



村上春樹的小說 Norwegian Wood 中,有一個在精神病療養院住了七年的人物的故事讓我特別感觸︰ 

Reiko 自小是音樂天才,她是學院裡的尖子,畢業後就要到德國進修,鋼琴就是她的整個生命。但有一日,剛好在重要的比賽臨近時,她的左手手指突然動不了,據診斷說是心理問題,大概是來自比賽的壓力,醫生告訴她她沒有作為演奏家的精神力量,還是放棄比較好。
"I had started playing when I was four and grew up thinking about the piano and nothing else. I never did housework so as not to injure my fingers. People paid attention to me for that one thing: my talent at the piano. Take the piano away from a girl who's grown up like that, and what's left? So then, snap! My mind became a complete jumble. Total darkness.

"It was as if my life had ended. Here I was in my early twenties and the best part of my life was over. Do you see how terrible that would be? I had such potential, then woke up one day and it had gone. No more applause, no one would make a big fuss over me, no one would tell me how wonderful I was ... I felt so miserable, I cried all the time. To think what I had missed!

"My parents walked around on tiptoe, afraid of hurting me. But I knew how disappointed they were. All of a sudden the daughter they had been so proud of was an ex-mental-patient. They couldn't even marry me off. When you're living with people, you sense what they're feeling, and I hated it. I was afraid to go out, afraid the neighbours were talking about me."

事情就是這樣的︰我們自小就會不斷努力爭取周圍的人對我們的愛和肯定,琴技、美貌、幽默、智識,那些讓我們自豪的特長,慢慢構成了我們人生的意義。但當你失去了你的美貌,你的幽默,或你的才華,你就會感到你喪失了所有價值,整個世界要不是在可憐你就是在嘲笑你,反正沒有人會喜歡你像個廢物般的一面。你感到你辜負了家人,你感到你是多餘的,你不再想見到任何人,你怕他們會談論你,但同時你又會因寂寞而徹夜不眠。最後,你會打算以自殺來結束你對自己的無比厭惡。

七年前,我有一個很要好的朋友自殺身亡,那年他十八歲,我十七歲,我完全無法理解為何身邊一個看似無憂無慮的人會突然自殺,也沒有其他人知道原因。

最後我花了七年時間來理解他。

面目模糊的弱者

印象記得之前有研究說,人們會較容易同情天災或意外的受難者,而較難同情因戰爭或受他人惡意所害的人,因為前者不能避免,而對於後者,我們較容易想像出一些理由去怪責受害者,例如女人被強姦是因為她們穿著不檢點,巴勒斯坦人被屠殺自然也是因為「他們也有錯」。所以相對於每日數以百計地死亡的有「嫌疑」的巴人,我們會遠遠較關心馬航的那些絕對無辜者。

波士頓馬拉松爆炸案可能也是這種邏輯,我們較易想像那些馬拉松選手都是絕對無辜的,而較難去想像活在中東的平民也是絕對無辜的。受傳媒影響,我們的腦自動就把阿拉伯人和極端狂熱份子的形象聯繫起來,因為除了這些新聞上可見的形象,我們就已經沒有更多知識去供我們去想像那些面目模糊的人。但當我們一說美國人,就能立即想起那些我們在電影和電視上見過了具體形象︰熱愛家庭的白人男性、旅行時墮入愛河的金髮美女、災難時勇敢救人的英雄 ......

大概沒有人能有完全平等的愛,但至少我想我們應該要對自己有要求,至少對媒體和娛樂工業的影響有所警覺,並誠實地去了解自己︰愛護弱小不是我們的天性,我們的天性是去愛那些給我們印象親切的人,而能夠控制什麼人能夠經常在媒體、廣告、娛樂產品上出現的,不會是真正的弱小--也可以說,我們的天性是偏愛強者。至少當我們不再偽善時,就有機會憑意志和理性去改造我們的天性,真正地學會不加差別地憐憫弱者。

後記︰看看這段為流浪漢穿上西裝後反而得到更多路人捐助的影片
