淺論新自由主義 (Libertarianism)

新自由主義支持自由市場經濟﹐反對政府用任何理由干預市場﹐或者用公平為名去重新分配資源﹐所以要支持資本主義(Capitalsim)。支持資本主義的人不一定支持新自由主義﹐他們雖然認為資本主義不完美﹐但是這是可以實行的方案中最好的選擇。他們可以用功用主義去作出推論﹐指出資本主義可以生產最多資源﹐最能夠滿足最多人的需要﹐達至功用最大化。他們亦可以從保障人權自由方便入手﹐指出大政府主義權力集中必然會腐化﹐Fedrick Hayek在其著作自由到勞役之路中﹐就說明自由市場對人權的重要性。這兩個支持資本主義的論點﹐是基於通過驗證的基礎上﹐沒有內在的必然性。如果發明新的制度可以讓功用最大化﹐又或者一樣能夠有效保障人權﹐則沒有理由繼續支資本主義。

新自由主義從另一個角度支持自由市場﹐說政府分配資源在本質不對﹐因為這樣做政府就會侵犯人民的權益。每個人有權決定如何使用他擁有的資源﹐政府若用稅收去掠奪人民的資源﹐就等同於強迫人民做奴隸﹐有違人類最基本的道德權益。Robert Nozick提出以下兩個論點﹕

  1. 擁有理論 (Entitlement Theory)
    如果每個人最初公平地擁有資源﹐通過自願合法的市場交易﹐達至一個新的資源分佈﹐則這個新的資源分佈也是同樣公平。如果政府要夾硬重新分配資源﹐則是不公平地影響人民的生活。

這個理論的反對者提出﹐現實中資源最初根本沒有公平分配﹐那就不能推論出其後的分佈也是公平。理論上Nozick支持一次過分配﹐分配過以後不論如何貧富懸殊也是公平。這個理論主要是反對新自由主義中﹐政府要不停地作出資源分配才可以有公平。留意一點是Nozick對公平的定義﹐與Rawls公平的定義不同。Rawls的公平是均分﹐Nozick的公平是擁有權。

  1. 自主理論 (Self-Ownership Argument)
    首先我對自己有主權﹐不是屬於任何人﹐我完全擁有我的材幹﹐所以我擁有用我的材幹生產出來的資源。若政府強制重新分配資源﹐我就要交出我的所有去給其他人﹐那樣我就淪為別人的生財工具。而把人視為只有工具價值不乎合道德﹐所以強制分配資源不道德。

這個理論的最大弱點﹐是忽視單單材幹不足以生產資源﹐還是需要在人身個體以外的產業﹐如土地或生產公具等。要確立這些外在財產的所有權﹐則又回到擁有理論的問題。不過隨著知識型和服務型經濟的發展﹐資源生產對外在產業的需求減少﹐自主理論在某些方便可以成立。

David Gautheir則從社會契約入手﹐去找出支持新自由主義的理據。他與Rawls的社會契約不同之處﹐是他包括人天生材能各有不同這個現實。由於每個人的材能不同﹐每一個人的議價能力也不同。一個有效的契約﹐除了所有人也為自己爭取最大益處外﹐還要可以實行﹐不然就只是紙上談兵。社會契約是基於共同利益﹐自主權衍生資源擁有權對每個人也有益處﹐可是重新分配資源只對小部份人有益處﹐而那些人沒有能力實行資源分配﹐所以他們根本沒有議價能力﹐所以新自由主義是現實中最好的社會契約。

反對者說這個社會契約沒有考慮公義﹐Gautheir回應他們公義的定義有問題。他們的公義憑空變出來無中生有﹐只是他們一廂情願的主觀想法。這已經超出政治哲學笵圍﹐涉及道德理論﹐探討道德從來而來的問題。前者假定公義是客觀的道德標準﹐而後者則假定道德不能違反自然定律。

最後說說七十年代在西方興起﹐九十年代未開始未落的福利主義。自由主義者通常支持福利主義﹐認為資源分配幫助窮人的最好方法。資本主義者也認為要幫助窮人﹐不過他們認為讓窮人自力更生才是最好方法。他們指出福利主義有以下幾個問題﹐養懶人﹐養成窮人依賴福利的習慣﹐政府根本沒有施政能力﹐福利政策設計上嚴重失誤﹐甚至越幫越差。這些問題有現實數據支持﹐自由主義者不能無視福利主義的是否有效的問題。

淺論自由主義 (Liberalism)

自由主義是哲學家John Rawls提出﹐在七十年代興起至今差不多半個世紀﹐一直深受是西方左派社運份子喜愛。他不滿意功用主義與傳統道德理論差太遠﹐可是另一邊廂的道德直覺主義又是一盤散沙﹐有很多互相衡突的道德金科玉律﹐沒有完整系統去制定社會政策﹐於是提出新自由主義填補這個空缺。新自由主義有兩大教條分別是﹕

  1. 一個公義的社會就是公平的社會﹐每個人的基本人權﹐利益受到保障。這項教條本身沒有什麼爭議性﹐與古典自由主義的思想一脈相成﹐第二項教條可是破天荒的新理論﹐改變西方政治理論的討論方向﹐成為學者討論其他理論比較的基準點﹐或曰慘成為天下圍攻的箭靶。

2.資源的分配比需遵守最大化最不幸社群利期的準則。換一句話說﹐公平的定義是資源均分﹐除非不均分配可以讓最差一群人也最受惠。舉個例子﹐上層﹐中產﹐基層有四個資源的分配安案﹐
A. 9, 4, 1
B. 8, 6, 2
C. 5, 4, 4
D. 3, 3, 3
自由主義必需要選擇第三個方案﹐不選擇極不公平的第一個方案原因很明顯。不選第四個方案是因為均貧﹐但反對資源最大化的第二個方案就有待相確了。第二教條一般稱之為不同定律(difference principle)

支持新自由主義的不同定律主要有兩個論點

  1. 社會契約論
    假若每一個人也是自私和理性﹐若果我們投胎前不知道我們在社會上的起點﹐例如不知道父母是否有錢﹐不知道有沒有天賦材能。在沒有任何資訊的情況下﹐選擇新自由主義的不同定律是最好的社會契約。因為跟據風險最小化的推論﹐我們就算不幸生為基層﹐也希望有好日子過﹐所以就要把基層利益最大化了。

當然也有人會批評假設性的社會契約不切實際﹐現實沒可能出現無知的選擇。可是這是一個哲學性的思想實驗﹐理性中的理論不定要從現實出發﹐可以是先得出結果﹐再把現實理朝想方向改造。

最大問題是這個推論有一個盲點﹐忘記了機會率的風險評估和人性的賭徒心理。若選擇基層利益為勉強可以過活﹐就有機會博進入生活中上層享受榮華富貴﹐反正生在上中下三層的機會也是均等的。所以只保障基層的最低生活標準﹐也不失為一個可以接受的社會契約。

  1. 公平推論
    古典自由主義保障基本人權﹐讓人可以在公平的情況下自由競爭。可是由為人生出來就是不平等﹐有些人家境富裕﹐有些人天資聰資﹐在公平競爭下的起步點全靠運氣安排﹐因此社會就要通過資源分配﹐讓所有人在同一的起步點開始競爭﹐所以就支持不同定律了。

這個公平推論看似有效﹐但是必須解答以下這些問題。

命生得好有運氣成份﹐可是成功也要靠運氣。一個出身寒微﹐天資平平的人﹐可以因為後天的努力和機緣巧合﹐成為一個坐擁巨大資源成功的人士﹐在起點公平下﹐他沒有理由要把資源分給其他人﹐所以不同定律就不成立。若一個人可以靠後天的好運氣﹐那不可以靠先天的好運氣就是不公平了。若果要把後天的好運氣的因素也除去﹐一來是實際上不可能做到﹐若要硬實行那人就會變得和機械人就沒有分別﹐所有事情也是整定。

其次就是不同定律沒有指明資源要代代清﹐若一個父母通過自身的努力﹐他們有權決定如何去使用賺取或分配到的資源。他們可以望子成龍的心態﹐希望子女未來有更好的生活﹐犧牲自己的可以享受的資源去裁培兒女。換一句話說強行要把人有起步點拉平﹐就會損害了父母公平使用資源的權利。

要把所有人的起步點拉平聽好像很公平﹐可是卻不切實際的空想。給窮家子弟獎學金升學﹐或為與建方便傷殘人仕的設施沒有大問題。可是對於一些嚴重殘障或弱智人士﹐不論投放多少資源他們也不可能公平競爭。基於不同定律的公平原則下﹐我們要把資源無限地掉入沒有回報黑洞﹐最終只會導至均貧。若把上限定為資源分均﹐則無視不同人有不同需要。若把資源分配與回報掛釣﹐則會變成自由主義所批評的功用主義。

最後就是養懶人的問題﹐基層所以窮有時候不全因為天生不幸﹐不同定律不能解決這個問題﹐因為沒有辨去細分基層的成因﹐這亦是福利主義常被批評的地方。做又三十六﹐唔做又三十六﹐與我們心目中公平的定義不乎。

淺論功用主義 (Utilitariainsim)

很多人對功用主義有錯誤的理解﹐妨忽談功用就好像不道德似的。其實功用主義是眾多道德理論之一﹐主要解釋道德從何而來﹐何謂對何謂錯。哲學家John Stuart Mill所提出的功利主義的吸引力在於沒有既定立場﹐不需要神喻亦不需要無中生有的規條﹐由客觀的事實結果去決定道德立場﹐在一般人眼中功利主義的定義﹐就是要為最多人追求最好的生活。其實這個定義不太準確﹐功利主義可以細分為三個層面。

  1. 何謂好﹐何謂功用
    傳統上功用主義好的定義是快樂﹐認為快樂是人所追求的共同值價。若人生只是追求快樂﹐全人類也吃食了會興奮迷幻藥不就是功用最大化嗎﹖所以人追求的值價很明顯不單只是快樂﹐還有其他的值價如豐富的生命﹐不同的人生經驗﹐甚至有時會是用痛苦辛勞換來的成功感。不過這又衍生出Matrix的問題﹐若單單經驗就是好的話﹐把全人類全捉入虛擬世界不就是功用最大化嗎﹖這不是我們落於見到的事﹐擁有創作一首詩的體驗﹐是等擁有同創作出一首詩這一個成果。

另一派的理論把好定義為人的自由意願﹐功用最大化就是滿足最多人的意願。可是很多人的意願不一定是好﹐甚至對自身有害﹐例如抽煙吸毒嗜賭等﹐滿足最多人的意願不能擔保結果一定是最好。其次意願會受環境因表影響﹐心理上會選擇次一等的意願﹐而不是真正的理想。例如酸葡萄心理作祟﹐生得醜就現實地說自己不希罕當港姐。可是就算每個人是足夠知識和理性﹐在天資家垃大至相若的情況下﹐所選擇的意願也會各不相同。現實上沒有一條公式可以衡量不同的意願的功用﹐更枉論說計算功用最大化。

功用的定義雖然在理論上不完美﹐但在實施中可以用相應的作出補救。加強教育鼓勵知識流通可以讓人作出最佳的理性選擇。不分配直接的意願﹐改為分配可以間接該意願實現的資源﹐就可以繞過量化不同意願的問題。功用主義中好的定義﹐大約可以最多的資源﹐最有效率的生產力去決定。

  1. 何謂對﹐如何最大化
    一件事情是對是錯﹐在功用主義的角度去看是最終的結果決定一切。姑勿論選擇那一個好的定義﹐只要一件事最終可以把功用最大化﹐那就是正確合乎道德的事情。這個推論產生出幾個問題。

很多時候我們根本不可能預知結果﹐事後功用是否最大化也無從考證。

若只是向前看只論結果的話﹐那就會忽略歷史因素的考慮﹐可能以功用最大化為理由﹐違反遵守諾言履行合約等基本道德精神。例如債仔可以對債主說﹐有錢應該不還而要捐給宣明會﹐因為非洲的飢民比債主更需要那筆錢。

若以滿足最多人的意願為前題﹐不能排除有人的意願意明顯有道德問題﹐如種族歧視或虐殺施暴的變態﹐這很明顯與我們的道德相違。例子有古羅馬的奴隸競技遊戲﹐殺幾個奴隸就可以帶給全城歡樂。

最詭異的論點是功用主義的矛盾﹐正因為在應用層面上有這麼多問題﹐不實行功用主義才可以把功用最大化。至少對大部份民眾日常生活而言﹐記著要遵守一套道德規律就足夠了﹐不用凡事也作功用的計算。功用的計算就留給學者去做﹐制定政策推廣那套道德規律。不過這就會成為精英主義﹐像英國在舊殖民地的半愚民政策統治。

  1. 何謂最大化﹐何謂平等
    功用主義的有兩個南轅北轍基礎理論﹐去解釋為什麼我們要支持功用主義。

第一個理論是假定每個人的意願也是平等﹐用邊際效益計算﹐所以每個人的利益要均分﹐得出平等就是等同功用最大化。問題是邊際效益的假設不一定成立﹐每個人的對社會的供獻和需求不同﹐像份餅仔般把資源均分很有可能不是得出資源最大化的結果。

第二個理論從相反的方向入手﹐把對的定義介定為功用最大化的結果﹐不論採用那一個功用的定義﹐資源的分配就是要把功用最大化。資源不一定要平均分配﹐可以是資源集中去提高生產力創造更多資源。問題是這個理論把人平等地視為功用的工具﹐與傳統人本道德理論不乎。不過也有哲學家支持這個想法﹐例如尼采認為創造是最高的道德﹐所以大部份凡人應該支持小部份天材去創新改進社會。

功用主義發源於十八世紀啟蒙改革年代﹐當時的社會由無能的貴族操控﹐以大部份人民利益為出發點的功用主義﹐就很自然成為改革的核心思想。在今天西方民主社會中﹐大部份人民的利益已經受到相當程度的保障﹐課題變成保障小部份不同聲音的利益。由於功用主義在功用的定義很空泛﹐由左至右不同的政治光譜的派系﹐也有其對功用不同的見解﹐得出的最大化的結果也不盡相同。不過各個政治派系有一個共通點﹐就非常強調重視理性的結果論﹐因為結果是檢定該推行什麼政策的唯一方法。

哲學功課﹕ 關你叉事定律 On Liberty – John Stuart Mill

今個長週未我嘔心瀝血地躲在家中寫文﹐原本上星期要交的功課我問教授延期﹐這就是上星期去了夏威夷的代價。橫掂寫好了貼上來﹐雖然也不期望有幾多人會看得明白﹐又或其實大部人見了一大堆雞腸就不會看。

先介紹一下John Stuart Mill吧。此君是第一個提出現在政治法律哲學理念的人。他最出名的理論是“關你叉事定律”﹐說政府只可以應該有權力去防止市民作出傷害他人的行為﹐如果他對自己不好(可能只是主流社會主觀地認為不好)影響不到別人﹐政府就不應干涉他的私人生活。套用俗一點的說法﹐就是 “又影響唔到你﹐老子鐘意點就點﹐關你叉事呀﹗”

這個定律的應用層面很廣﹐由食煙吸毒至搞基信邪教的法例﹐無一不受這個定律影響。我這篇文章是評論他的經典名著On Liberty﹐看看他的關你叉事定律的立論是否合理

On Liberty – John Stuart Mill

Introduction:
In modern political philosophy classics, On Liberty, John Stuart Mill discusses the proper limit of the power the government and society can assert over individuals. He applies the principle of utilitarianism to argue that setting up our legal system based on the harm to other principle is best for the society. In this essay, I will comment Mill’s two arguments supporting his viewpoint in liberty of action by showing their weaknesses. I am not rejecting Mill’s idea on liberty and individual freedom. In the matter of fact, I believe Mill’s work is a corner stone of modern legal systems. I am only demonstrating his arguments are not sufficient to support the conclusion. First I will start by explaining a few definitions in his book to clarity some key ideas.

Definition of terms:
Harm to others principle: The harm to others principle states that the government can only interfere with the actions of its people when the actions are causing harm to others. The government can only punish individuals harming others directly by his action, or indirectly by his inaction through neglecting his duty to the society. The government is not justified to punish people if their action only brings harm to themselves but not others. This principle not only applies to limiting the power of the legal system but also applies to limiting the power of the public opinion, which pressures individuals to conform through moral pressure.

Paternalism: The government and the public opinion acts as the parent of its people, using force to prevent the people harming themselves.

Soft-Paternalism: The government and the public opinion only assert controls on minors or incompetent people who lack rational judgement for their own good. According to Mill, soft-paternalism can also apply to uncivilised races that could not govern themselves.

Hard-Paternalism: The government and the public opinion assert control on adults and component people in the society for their own good.

Enforcement of morality: The government and public opinion interferes self regarding actions of individuals based on morality.

Mill rejects hard-paternalism and enforcement of morality based on the harm to others principle. However he adopts soft-paternalism for obvious practical reasons. Mill has developed two lines of argument to support his view of proper scope of individual liberty of action based on the harm to other principle. In the following paragraphs, I will first outline the arguments, followed by my criticisms to the arguments and Mill’s potential responses. At last I will evaluate whether Mill has successfully defended his view on liberty of action.

Argument from social progress:
Mill first establishes his argument of encouraging individuality will lead to greater good in the society from two sub-arguments: the opposing the despotism of custom and the creation of genius. He thinks allowing individuals to choose his own life will leads to a better life in term of happiness and development. Traditions and custom will limit liberty if they are followed blindly. People should have the right to examine existing customs and decide which one to follow by making rational choices. Mills thinks many people follows customs are merely copying what others do from their experience, without reflecting whether the customs are good or bad. He also thinks geniuses are one of the most important factors in making progress in our society. In other to cultivate geniuses, who are often different from normal people, we need a society with an atmosphere of freedom and variety of situations. He uses examples of collective meritocracy in middle age Europe and eighteen centuries China to support this argument. After his argument for liberty is secured, he further develops his argument that the harm to other principle is necessary to archive this kind of freedom in the society by allowing people to freely express themselves. From the utilitarian perspective, it is beyond dispute that greater good for the society is always desired. Therefore, Mills concludes that we should adopt the harm to others principle for the greater good for the society.

Argument form individual judgement:
Mill starts his argument by defining the difference between self regarding actions and other regarding actions. Our society is formed based on unwritten social contract agreed by all the members. Every individual enjoys the right and benefits being a member of the society in return for bearing his fair share of responsibility. Therefore those who violate the rights of others should be punished by the society, since it is one of its major functions. According to Mills, the society should not interfere with individuals’ self regarding, which only affect the person himself but not others. He states that each rational person has more interest in promoting his own well being than the good for others. He has better knowledge about what is best for himself than anyone one else. Therefore society should not force him to follow the judgement of other people by punishing his wrong doing in the eyes of others. The society may warn him the danger and consequence of his action, but should let him be the final judge. He should bear no more punishment than the natural consequence of his action if that does not affect others. Other people in the society have the right to avoid him or express their distastes towards his action. Mills says the society can only overrule the judgement of individual by legal means if there is a firm ground he is incapable of making the right judgement. Therefore, we should adopt the harm to others principle to respect individual judgements.

Criticism against argument from social progress:
My objection to Mill’s social progress argument is that he assumes tradition and customs are arbitrary rules come from the thin air. He doesn’t realize customs are created to serve the better good for the society in the first place. People follow customs not because they are forced to but because in most of the time custom is the most efficient and convenient way to solve the problems in the society. It is true that when technology progress and situation changes, some customs become out of date and can no longer serve their purpose. Since customs carry their own momentum, the society may take a long to correct itself when customs obsolete. In order to help the society archive higher efficient and progress sooner than later, the society should have the right to uplift those who hang on to old custom through jurisdiction. For example, according to Mill’s argument, we should allow the Amish or Indian reserves continue on their pre-industrial way of living, provided that it is their own choice. It is evidently that the society would progress faster and everyone will lead to a better life if we can modernize the Amish and Native Indians. Therefore, we should only reject the deposition of obsolete and inefficient customs that hinder progress. We should not throw away the baby with bath water by rejecting the deposition of newer and more efficient custom to those who refuse to change.

Defence for argument from social progress:
Mill may attempt to reply my criticism by claiming we are merely flattering ourselves that we are the most progress people who ever lived. He could argue the old customs may better serve the society than the new customs. However, if we study Mill more carefully, we will find that he worries the society will become stagnated if changes are not allowed or too slow. He does not worry about changes happening too fast. In the matter of fact he uses the harm to other principle to encourage changes. I think he may actually agree with my criticism that the harm to others principle is not sufficiently justified by social progress alone. Since he supports soft-paternalism, maybe he can revise his position by stating those who cannot adapt to changes are non-competent people. The enlightened people have the right to impose the new customs on to the losers in the game of social Darwinism.

Criticism against argument from individual judgement:
My object to Mill’s individual argument is that the harm to other principle is self contradictory if we follow the train of thoughts in this argument. According to the harm to other principle, the government only interfere when individuals are causing harm to others. What about individuals interfere with others for good causes out of altruism? According to Mills, the government should not punish those people. Therefore each individual are free to enforce their morality on other as they see fit. For example, a person can take away the cigarette of a smoker because stopping him from smoking is not causing him any harm. A doctor is free to perform blood transfusion on a believer of Jehovah Witness against his will also because it does not cause him any harm. Moreover, Mill agrees that individuals can avoid and openly caution others against those they feel distasted. In a modern society based on division of labour, if the majority are free to isolate the minority, the minority are in effect excommunicated from the society. Put it in another words, Mill’s harm to others principle allows discrimination against the minority. The inaction or avoidance of each individual in the majority group doesn’t violate the harm to others principle. However collectively, the majority can control the actions of the minority through moral coercion of public opinion.

Defence for argument from individual judgement:
Mill may response to my criticism by saying that twisting the harm to other principle against itself violates the spirit of the principle. The principle is intended to protect the liberty of action of the minority from the majority. The majority exploiting the loopholes in the principle will not bring the society any good. Granted, he is right to condemn those abusing the principle based on the utilitarian argument. However Mill has no choice but patch the harm to other principle to avoid such undesired consequences. He may add further constraint to the principle by including more actions besides those causing harm to others or adding secondary principle to seal up the loopholes. I think no matter which solution he picks, he nullifies the argument from individual judgement in its original form.

Conclusion:
In conclusion, I think my criticism on Mill’s view on liberty of action is in good faith. I have no intention to reject the fundamental idea of Mill’s political philosophy on individual freedom. By pointing out the inconsistency in Mill’s theory, I helped discover some potential problem in the implementation of the harm to others principle. Although Mill’s response to my criticism cannot defence his original argument for the principle, he may addressing those issues with a revised version of principle. I think my criticisms have no negative effects on Mill’s place in modern political philosophy. Instead my criticisms strengthen Mill’s position on liberty and power of the government.

PHIL203 Metaphysics 形上學

Metaphysics 這個學期我修讀的是形上學(Metaphysics)﹐這課本來不是我的首選。一來上學期讀完Hume大肆批評形上學廢﹐二來上課時間在中午很不方便。不過晚上那班倫理進階滿額了﹐加上哲學部門的指導教授說我的根基未穩﹐建議我先在二年級的課中打好基礎﹐於我逢星期一三的午飯時間﹐便會從公司開溜回大學上堂﹐成為班中唯一一個邊吃飯盒邊抄筆記的人。

讀形上學的確沒有什麼實際的用途﹐它不像認知論背負起整個現代科學的基礎﹐也不像倫理學般關乎切身的社會問題。形上學研究超越這個世界﹐不在受制於現實的物理層面的東西﹐嚴格來說可以說是純吹水。不過這些看似吹水的題目﹐卻困繞了哲學家二千幾年也找不到答案﹐理論上亦不可能找到答案。形上學的課題主要有﹐體肉和靈魂的關係﹐人有沒有自由意志﹐時間是什麼﹐神存不存在﹐自我的身份問題﹐以及最重要的一個題目﹐人生宇宙的終極意義是什麼。形上學也不是完全沒有用﹐它的最大用途就是當宗教的解毒劑。很多人會往宗教處找這些問題的答案﹐而宗教也提供了一個很方便答案﹐人們也不再深究思考其答案的真偽﹐安心地被宗教利用答案去達到其他目的。

這課的教授很用心授課﹐指定課本只是薄薄的一本作為問題的導讀﹐該書的作者對各問題的答案有既定立場。教授把其他正反相方哲學家的文章﹐結集在比課本還要厚出許多的講義上﹐讓我們能夠更深入了解問題的本質。靈魂肉體問題和自由意志這兩個課題差不多用了半個學期去教﹐深入剖析各正反論點的優劣﹐雖然到最後也沒有一個肯定的答案﹐但正方的理據讓我更加深信靈魂和自由意志的存在。不過也有可能先入為主﹐因從小被灌輸的社會觀念﹐下意識地不斷嘗試推翻反方的論點。

在靈魂問題上最大的難題﹐就是肉體和靈魂的互動介面。不過哲學家對科技總是落後幾步﹐從電腦工程師的角度去看﹐靈魂就好像電腦軟件﹐肉體就是硬件﹐人的意識就是靈魂。我會相信電腦有可能有靈魂﹐但反而接受不到動物有靈魂。自由意志的問題﹐是因為它和理定律的必然性或全知神的屬性有矛盾﹐不過我很自然的引用量子力學中的隨機現像去反駁必然性這點。不過自由意志這個問題申延出的道德問題才是核心所在﹐因為所有的道德理論也是建立在人可自由選擇好壞的基礎上。完全不受控也是沒有自由意志﹐所以隨機論還是解決不了責任的問題。

時間課題給我的感覺是與時代俗節﹐大慨沒有多少人會懷疑時間的真實性。我的第二篇功課特別選了這個題目﹐用霍金的時間簡史和愛因基坦的相對論﹐去逐點反駁主張時間是不真實的上世紀哲學家。 我認為時間和萬有引力般﹐應該從哲學搬家到物理學﹐不用再齋講時間是什麼﹐做實驗去發掘是更好嗎﹖我原本以為神存不存會是個很熱門課題﹐不過竟然只有老掉牙的理論﹐大慨哲學家們對神早已有共識﹐只剩下宗教份子還會喋喋不休地說神。自我身份這個課題很有趣﹐除著科技發達﹐也許在不久的將來﹐我們會有腦袋移植﹐複製人﹐思想拷貝等技術。那候誰才是我的這個問題﹐也許就不再那樣抽像難以捉摸﹐變成和日常生活息息相關的事情了。

形上學最後的一個課題是意義的問題。我曾經和同事玩蘇格拉底式問答﹐用深入淺出的方法去告訴他什麼是形上學。結果最後一定會問到這個問題﹐人生的意義是什麼﹐人為什麼要存在。這個問題的答案是沒有得學﹐每一個人的也不盡相同﹐必需要自己去思索找出心中的那一個答案。不過這個課題不用考試﹐我到現在還沒有時間去好好地思考答案。我以前做過九型人格的心理測試﹐我是很少有的享樂主義者﹐幾十人一起做測試只有我一人。說不定我的人生意義就只是吃喝拉睡﹐說起來其實這也不算太壞。

修讀這課比起哲學入門吃力﹐可能要閱讀比較多的原著﹐加上在日間上堂。分數方便我依然是低空飛過僅僅及格﹐大慨我在文科上沒有什麼天份。寫文章雖然不太在行﹐但我自信可以明白這課中學到的理論的大部份。不過想果當一個哲學家﹐自己明白了問題找到答案是不足夠的。更重要是人家知道你找到答案﹐就算不同意也要至少知道你想講什麼。
