The Two Truths and the West 二諦與西方哲學

The Buddha said there is no self, and he also said “I” and spoke of persons, their deeds, and their rebirths. The two truths are the tradition’s account of how both can be right. Why Kant’s two standpoints and the physicist’s two tables come close, where each falls short, and how to stop a listener from hearing “conventional” as “false.”
佛陀說沒有我;他也說「我」,也談人、人的行為與人的再生。二諦,就是這個傳統對「兩者怎麼可能都對」的說明。康德的兩個立足點、物理學家的兩張桌子,為什麼很接近?各自差在哪裡?又該怎麼讓聽眾不把「世俗」聽成「假的」?

The verdict · 判定

Closest: Kant, for whom the world of experience is empirically real and not real in itself. Wilfrid Sellars’s two images of the world are closest to the older Buddhist version, in which the chariot is conventional and its parts ultimate. The likeness to Kant ends at the ultimate. For Kant it is a thing in itself that we can never know. For Nāgārjuna the ultimate truth is knowable, and it is nothing over and above the conventional: it is the fact that conventional things are empty.

最接近的是康德:對他來說,經驗的世界在經驗上是真實的,卻不是「本身」真實的。威爾弗里德・塞拉斯的兩幅世界圖像,最接近較早的佛教版本:車是世俗的,它的零件是勝義的。跟康德的相似,到勝義為止。對康德來說,那是我們永遠無法認識的物自身。對龍樹來說,勝義諦是可以認識的;而它並不是世俗之外另有的什麼東西:它就是「世俗的事物是空的」這項事實。

1 · What the Dharma says · 佛法怎麼說

How to say “I” without a self 沒有「我」,怎麼說「我」

The problem appears in the earliest texts. The Buddha taught that no self is to be found, and he went on using the words everyone uses. A deity asked whether a monk who has reached the goal would still say “I speak” and “they speak to me.” He would, the Buddha answered. “Skillful, understanding the world’s labels, they’d use these terms as mere expressions.” Elsewhere, after listing the ordinary names for things, he says: “These are the world’s common usages, definitions, expressions, and descriptions, which the Realized One uses to communicate without getting stuck on them.” The nun Vajirā gave the classic image when Māra tried to unsettle her with questions about who made this being. “When the parts are assembled we use the word ‘chariot’. So too, when the aggregates are present ‘sentient being’ is the convention we use.”

這個問題在最早的經典裡就出現了。佛陀教導說找不到「我」;而他繼續使用人人都在用的字眼。一位天神問:一位已經達到目標的比丘,還會說「我說」與「他們對我說」嗎?佛陀回答:會的。「他善巧,了知世間的名稱;只把這些字眼當作言說來用。」在別處,他列舉了事物尋常的名稱之後說:「這些是世間的通稱、詞語、言說與施設;如來用它們來溝通,而不被它們卡住。」當魔羅用「是誰造了這個眾生」這樣的問題來擾亂金剛比丘尼的時候,她給出了那個經典的意象:「零件湊合起來的時候,我們就用『車』這個字。同樣地,諸蘊在的時候,『眾生』就是我們所用的通稱。」

The early schools turned this into a doctrine of two kinds of statement. Some of the Buddha’s words describe things as they are finally analyzed: aggregates, sense bases, moments of feeling. Others use the names of wholes: a person, a chariot, an army. Statements of the second kind are true by convention. They are useful and correct in their place, and what they name can be resolved into the items of the first kind. The Buddha himself warned against confusing the two registers. A person misrepresents him, he said, who “explains a discourse in need of interpretation as a discourse whose meaning is explicit,” or the reverse. On this version the ultimate is what is left when analysis is finished.

早期的各部派,把這變成了一個關於兩種陳述的學說。佛陀的話,有些描述的是事物被分析到底的樣子:蘊、處、一剎那一剎那的感受。另一些用的是整體的名稱:一個人、一輛車、一支軍隊。第二種陳述,是依世俗而為真的。它們在自己的位置上有用、也正確;而它們所命名的東西,可以被拆解成第一種的項目。佛陀自己警告過,不要把這兩個層次混淆。他說:把「不了義的經說成了義的經」的人,是在誣謗他;反過來也一樣。照這個版本,勝義就是分析做到底之後剩下來的東西。

Nāgārjuna kept the two truths and changed what the second one is. “The Buddhas teach the Dharma by relying on two truths: the conventional truth of the world, and the truth of ultimate meaning. Those who do not understand the distinction between the two truths do not understand the real meaning of the profound teaching.” His analysis did not stop at the parts. The parts are empty too, and no final layer of real things is reached. The ultimate truth about a chariot is that neither it nor its parts have own-nature. So the ultimate is no second world behind this one. It is the way this one is. He added a rule about order: “Without relying on the conventional, the ultimate cannot be attained. Without attaining the ultimate, nirvana cannot be attained.” The commentary gives the reason. The ultimate has to be spoken of, and all speech is conventional.

龍樹保留了二諦,卻改變了第二個諦是什麼。「諸佛依二諦,為眾生說法:一以世俗諦,二第一義諦。若人不能知,分別於二諦,則於深佛法,不知真實義。」他的分析並沒有停在零件上。零件也是空的;並沒有到達任何一層最終的實有之物。關於一輛車的勝義諦,就是:它與它的零件都沒有自性。所以,勝義並不是這個世界背後的第二個世界。它就是這個世界存在的方式。他還加了一條關於次序的規則:「若不依俗諦,不得第一義;不得第一義,則不得涅槃。」長行的解釋給出了理由:「第一義皆因言說,言說是世俗。」

The view it is not · 它不是的那種看法

Plato 柏拉圖c. 375 BCE

The Western tradition’s first and most influential two-level picture is Plato’s. There is the changing world that the senses show us, and there is the world of Forms that reason grasps, and the second is more real. The prisoners in the cave take shadows for things, and the philosopher climbs out to see the originals. Many Western readers assume that the Buddhist two truths are a version of this, with emptiness or nirvana in the place of the Forms and ordinary life as the shadows. The structure is reversed. Plato’s higher level contains the things that most fully exist, and each has a fixed nature. Nāgārjuna’s ultimate truth is that nothing has such a nature, and it is a truth about the things of this world, with no other location. A student who leaves the cave in Plato’s story arrives somewhere else. One who understands the two truths has not gone anywhere.

西方傳統裡第一個、也最有影響的兩層圖像,是柏拉圖的。有感官顯示給我們的那個變動的世界;也有理性所把握的那個理型的世界;而後者更真實。洞穴裡的囚犯把影子當成了東西;哲學家爬出去,看見了原物。許多西方的讀者假定,佛教的二諦是這個圖像的一個版本:空或涅槃在理型的位置上;日常生活則是影子。結構是反過來的。柏拉圖較高的那一層,裝的是存在得最充分的東西;每一樣都有固定的本性。龍樹的勝義諦是:沒有任何東西有那樣的本性;而它是關於這個世界裡的事物的一項真理,並沒有別的所在。在柏拉圖的故事裡,離開洞穴的學生到了另一個地方。懂得二諦的人,哪裡也沒去。

Real in experience, not in itself · 在經驗中真實;本身則不然

Immanuel Kant 康德1781

Kant held that space, time, and the order of causes belong to the way our minds take in the world. Within experience they are fully real. He maintained “the empirical reality of space in regard to all possible external experience, although we must admit its transcendental ideality,” that is, “that it is nothing, so soon as we withdraw the condition upon which the possibility of all experience depends.” This is close to the Madhyamaka formula: conventionally existent, ultimately empty. Both deny that the world as we find it exists in its own right, and both refuse to call it an illusion. They separate over the second level. Kant placed a thing in itself behind appearances and said that its nature “is quite unknown to us.” Nāgārjuna placed nothing behind them. He held that the ultimate can be known directly, and that what is known is the absence of anything standing behind.

康德主張:空間、時間與因果的秩序,屬於我們的心接收世界的方式。在經驗之內,它們是完全真實的。他主張「空間對一切可能的外在經驗而言,有經驗上的實在性;雖然我們必須承認它在先驗上的觀念性」;也就是說,「一旦我們拿掉一切經驗之所以可能的那個條件,它就什麼也不是」。這很接近中觀的公式:世俗上有,勝義上空。兩者都否認我們所見的這個世界是憑自己而存在的;兩者都拒絕把它稱為幻象。兩者在第二層上分開。康德在現象的背後放了一個物自身,並且說它的本性「我們完全不知道」。龍樹在現象的背後什麼也沒放。他主張勝義是可以直接被認識的;而被認識到的,正是「背後沒有站著任何東西」。

Two images of one world · 同一個世界的兩幅圖像

Wilfrid Sellars 塞拉斯1962

The physicist Arthur Eddington began a famous book by saying that he was writing at two tables: the solid, colored one of everyday life and the scientific one, mostly empty space with electric charges rushing about. The American philosopher Wilfrid Sellars made the contrast into a problem for philosophy. We have a manifest image of the world, in which there are persons who think, intend, and are responsible, and a scientific image, in which there are particles and fields. The task is to see how both can be held together. This matches the early Buddhist two truths almost exactly. The chariot and the person belong to the manifest image, and the ultimately real items are the ones a finished analysis would list. Sellars and the Abhidharma also agree that persons belong to the first image, and that this does not make talk of persons dispensable. They differ from Nāgārjuna in the same way. Sellars held that in describing what there is, science is the measure. Nāgārjuna held that the scientific image, like any other, is a conventional truth, and that no description reaches things with own-nature.

物理學家亞瑟・愛丁頓在一本名著的開頭說:他是在兩張桌子上寫作的。一張是日常生活裡那張堅實、有顏色的桌子;另一張是科學的桌子,大部分是空的空間,其中有電荷在疾馳。美國哲學家威爾弗里德・塞拉斯,把這個對比變成了哲學的一個問題。我們有一幅關於世界的「顯見圖像」:其中有會思考、有意圖、要負責的人。我們也有一幅「科學圖像」:其中有粒子與場。任務是看出兩者怎麼能夠並持。這與早期佛教的二諦幾乎完全對應。車與人屬於顯見圖像;而勝義上實有的項目,是一份做到底的分析會列出來的那些。塞拉斯與阿毘達磨也同意:人屬於第一幅圖像;而這並不使「談論人」變得可有可無。他們與龍樹的差別,是同一個。塞拉斯主張:在描述「有什麼」這件事上,科學是尺度。龍樹主張:科學圖像跟任何別的圖像一樣,是世俗諦;沒有任何一種描述,搆得到有自性的東西。

4 · Verdict · 判定

Who is closest, and where the likeness ends 誰最接近,相似到哪裡為止

Two Buddhist doctrines go by the name of the two truths, and each has its own nearest neighbor. The early version, in which wholes are conventional and their final constituents ultimate, is closest to Sellars and to scientific reduction generally. Any modern reader who says that a table is “really” atoms holds a two-truths view of that kind. The Madhyamaka version is closest to Kant, for whom the world is real for experience and not real in itself. Plato, who is usually the first comparison to come to mind, is the furthest of the three.

有兩個佛教的學說都叫作「二諦」;而每一個各有它最近的鄰居。早期的版本,也就是「整體是世俗的,它們最終的成分是勝義的」,最接近塞拉斯,也最接近一般所說的科學化約。任何一位說「桌子『其實』是原子」的現代讀者,持有的就是那一種二諦觀。中觀的版本最接近康德:對他來說,世界對經驗而言是真實的,本身則不是真實的。柏拉圖通常是人們最先想到的比較對象;而他是三者當中最遠的。

The likeness to Kant ends at three points. He has an unknowable something behind appearances, and Nāgārjuna has no such thing. He thinks the human mind is fixed in its forms and cannot see otherwise, and the Buddhist path is a training by which the ultimate comes to be seen. His two standpoints are a result in the theory of knowledge, and the two truths are a teaching device with a use. The Buddha spoke of persons to people who needed to hear about conduct and consequence, and of aggregates and emptiness to those ready to look into what a person is. The purpose of keeping both is that neither nihilism nor attachment to things follows. Kant wanted to show what we can know. Nāgārjuna wanted a way of speaking truthfully to everyone without confirming anyone’s clinging.

跟康德的相似,在三個地方為止。他在現象的背後有一個不可知的某物;龍樹沒有這樣的東西。他認為人心的形式是固定的,無法以別的方式來看;而佛教的道,是一種訓練,經由它,勝義得以被看見。他的兩個立足點,是知識論上的一個結果;二諦則是一件有用途的教學工具。佛陀對那些需要聽「行為與後果」的人談「人」;對那些準備好去探究「人是什麼」的人談蘊與空。同時保留兩者的目的,是使虛無主義與對事物的執著,兩者都推不出來。康德想要顯示我們能知道什麼。龍樹想要的,是一種能對每個人說真話、而又不去印證任何人的執取的說話方式。

5 · The step the Dharma takes further · 佛法多走的一步

No shortcut past the conventional 繞不過世俗

The first further step is the rule of order. Western two-level views generally treat the lower level as something to get beyond: out of the cave, behind the appearances, down to the particles. Nāgārjuna says that the ultimate is reached only by relying on the conventional, and the reason is practical. The path is made of conventional things: words, teachers, precepts, kindness to particular people. A student who announces that conduct is merely conventional and so does not matter has misunderstood both truths at once. The teaching anticipates him. Because actions and results hold conventionally, and conventional holding is the only kind there is, they hold in the fullest sense available. The lessons on emptiness and on the four corners reached the same point by other routes.

多走的第一步,就是那條關於次序的規則。西方的兩層看法,一般把較低的那一層當作要超越的東西:走出洞穴、到現象的背後、往下到粒子。龍樹說:只有依靠世俗,才到得了勝義;而理由是實際的。道,是由世俗的東西構成的:言語、老師、戒條、對特定的人的善意。一位宣稱「行為只是世俗的,所以不要緊」的學生,是把兩個諦一次都誤解了。這個教法早就料到了他。因為行為與結果是依世俗而成立的;而「依世俗而成立」是唯一有的那一種成立;所以它們是在現有的最充分的意義上成立的。講空與講四句的那兩課,從別的路到達了同一點。

The second step is that the two truths collapse the distance between the goal and the starting point. If the ultimate is the emptiness of this world and no other realm, then awakening is a change in how this world is seen. Nāgārjuna states the consequence in a verse that startled his readers: “Between nirvana and the world there is not the slightest difference. Between the world and nirvana there is not the slightest difference.” The commentary explains that both are empty and unarisen, so that no line can be drawn between them. He does not mean that ordinary confusion is already awakening. The Chinese and Japanese schools built much on this verse, and it gave the Mahāyāna its characteristic confidence that practice is done in the middle of ordinary life. It also explains why the bodhisattva does not leave. On Plato’s picture the one who gets out has a reason not to come back. On this one there is nowhere else to be.

第二步是:二諦把目標與起點之間的距離收攏了。如果勝義就是這個世界的空,而不是另一個境域;那麼,覺悟就是「怎麼看這個世界」的一個改變。龍樹用一首使他的讀者吃驚的偈,陳述了這個推論:「涅槃與世間,無有少分別;世間與涅槃,亦無少分別。」長行解釋說:兩者都是空的、不生的;所以在它們之間劃不出一條線。他的意思並不是:尋常的迷惑已經就是覺悟。漢傳與日本的各個宗派,在這首偈上建立了很多東西;而它給了大乘那種特有的信心:修行,就是在日常生活的當中進行的。它也解釋了菩薩為什麼不離開。照柏拉圖的圖像,走出去的那個人有理由不回來。照這個圖像,並沒有別的地方可去。

6 · How to say it to a Western audience · 對西方人怎麼講

Conventional does not mean false 世俗,並不是「假的」

In English “conventional” suggests something arbitrary, and “ultimate” suggests something higher and better. Together they tell the listener that Buddhism has a real truth and a pretend one, and that serious people concern themselves with the first. Start by repairing “conventional.” Money is the best example. A banknote is paper, and its value exists only because people treat it as valuable. No one concludes that money is unreal or that it does not matter whether you have any. Its value is conventional and entirely real in its effects. Persons, promises, and nations are like that. Then say what the ultimate truth is: the fact that this is how such things exist. It is the same things, correctly understood.

在英文裡,conventional 讓人想到某種任意的東西;ultimate 讓人想到某種更高、更好的東西。合在一起,它們告訴聽者:佛教有一個真的真理、一個假裝的真理;而認真的人關心的是前一個。先把 conventional 這個字修好。錢是最好的例子。一張鈔票是紙;它的價值之所以存在,只是因為人們把它當作有價值。沒有人會由此得出結論:錢是不真實的,或者「你有沒有錢」並不要緊。它的價值是約定俗成的;而它的作用完全是真的。人、承諾與國家,都是那樣。然後說出勝義諦是什麼:就是「這類東西是這樣存在的」這項事實。它是同樣的那些東西,被正確地理解了。

Sentences you can use 可以直接用的句子

  1. The Buddha taught that there is no self, and he still said “I.” The two truths explain how both are right.

    佛陀教導說沒有我;而他仍然說「我」。二諦解釋了兩者怎麼都是對的。

  2. Conventional truth is like money: it exists by agreement, and it is completely real in what it does.

    世俗諦就像錢:它靠約定而存在;而它所起的作用是完全真實的。

  3. The ultimate truth is not about another world. It is about how this one exists.

    勝義諦講的不是另一個世界。它講的是這個世界怎麼存在。

  4. Kant said the world is real for experience and not real in itself. Nāgārjuna agreed, and added that nothing is hidden behind it.

    康德說:世界對經驗而言是真實的,本身則不是真實的。龍樹同意;並且補了一句:它的背後並沒有藏著什麼。

  5. Nāgārjuna said that you cannot reach the ultimate without relying on the conventional. Ethics is where the path starts, and it is never left behind.

    龍樹說:不依靠世俗,就到不了勝義。倫理是這條道路開始的地方;而它從來不會被拋在後面。

  6. When someone says “that’s only conventional,” ask what else there is for a thing to be.

    當有人說「那只是世俗的」的時候,問他:一樣東西除此之外還能是什麼?

Phrases to avoid 要避開的說法

“Relative truth and absolute truth.” 「相對的真理與絕對的真理。」

“Absolute” brings in God or a hidden reality. Say “conventional” and “ultimate,” and explain both.

「絕對」把上帝或者某個隱藏的實在帶了進來。要說「世俗」與「勝義」;兩個都要解釋。

“Conventional truth is illusion.” 「世俗諦是幻象。」

Then the precepts are illusion too. Say that it is how things exist and function.

那麼戒也成了幻象。要說:它是事物存在與起作用的方式。

“Ultimately, nothing matters.” 「究竟來說,什麼都不要緊。」

Mixes the two truths. “Mattering” is conventional, and conventionally things matter a great deal.

這是把兩個諦攪在一起了。「要緊」是世俗層次的事;而在世俗上,事情非常要緊。

“Enlightened people are beyond good and evil.” 「覺悟的人超越了善惡。」

The Buddha kept the precepts until he died. Seeing the ultimate does not cancel the conventional.

佛陀持戒直到去世。看見勝義,並不取消世俗。
