What This Concept Is Saying

非缘 (apratyaya) is, on the surface, the most counter-intuitive member of a pair you have probably never consciously noticed: *缘* (pratyaya, condition) and *非缘* (apratyaya, "non-condition"). To understand why it has to exist at all, we have to start from the problem it is built to address — and that problem is one you and I commit dozens of times before breakfast.

The problem: "Conditions" feel like real things

When something happens, we almost involuntarily ask: *what caused it?* and *what conditions brought it about?* We treat conditions (缘) as identifiable objects in the world — discrete, nameable entities that produce other entities. The seed is the condition for the sprout. The rain is the condition for the wet street. The childhood pattern is the condition for the adult reaction. This seems so obvious it doesn't even look like a philosophical position. That is exactly why the Madhyamaka (中观, "Middle Way") tradition puts it on the operating table.

In 《中論·破因緣品》 (*Mūlamadhyamakakārikā*, "Examination of Causes and Conditions"), Nāgārjuna (龍樹) and the commentator Piṅgala (青目) take up the question of whether *pratyaya* (缘) — the conditioning factors in dependent origination — can be pinned down as a thing with self-nature (svabhāva, 自性). The chapter's argument produces *apratyaya* (非缘) along the way, but produces it for one reason only: to dissolve the very reification that gave it birth.

The rhetorical setup: how 非缘 is introduced

The chapter opens with a deceptively simple challenge recorded in the verses:

「因是法生果,是法名為緣;若是果未生,何不名非緣?」 "It is because a dharma gives rise to a fruit that it is called a 'condition'; if the fruit has not yet arisen, why not simply call it a 'non-condition'?"

This is a *vighraha* — a precision-engineered interrogation. The challenger is not asking us to invent a new metaphysical category. The challenger is asking us to notice that the label *condition* is bestowed *after the fact*, once a fruit has already appeared. So before the fruit appears, the so-called condition is not yet in possession of the very property that would make it a condition. If we are honest about this, then what we are calling *non-condition* is just the same thing, looked at from a slightly different angle.

Piṅgala's commentary makes the point with the example of a clay pot (瓶). We call water, clay, and fire "conditions of the pot" because we have *seen* a pot arise from their combination. That naming is a *post-hoc* designation (施設, *prajñapti*) — a label laid down after the event, not a property stamped into the things beforehand. So in the moment before a pot has appeared, water and clay do not "pre-know" that they are conditions; they certainly do not "pre-know" that they are non-conditions. The challenger was right to ask the question, and Piṅgala's answer is to expose how thin the category *condition* actually is.

This is the first lesson about 非缘: it is not the name of a thing. It is the name of a question that has been successfully raised against our habit of naming things as conditions.

The three-fold negation: the death of the fruit-in-the-condition

The chapter then refuses to let us retreat to a simpler position. The fruit (果, *phala*) — the supposed thing that conditions produce — must exist in the condition in one of three ways:

「若果非有生,亦復非無生,亦非有無生,何得言有緣?」 "If the fruit is not produced as already-existing, nor as non-existing, nor as both — how can one say there are conditions?"

Piṅgala walks through each:

1. 先有 (already-existing): If the fruit were already sitting inside the condition, then producing it would be redundant — the seed would already contain the sprout. This is the absurdity of "the acorn is already an oak tree." 2. 先無 (non-existing): If the fruit is wholly absent before production, then how does a nothing, taken in hand by a condition, become a definite *something*? Nothing does not turn into something by being touched by another nothing — that is just two nothings. 3. 有無並存 (both): This is supposed to be the safe middle, but it inherits all the problems of the first two and adds the problem of self-contradiction.

Once we cannot locate the fruit in the condition as either pre-existing, absent, or both, the *condition* (缘) loses the very thing that made it a condition — its relation to a determinate fruit. So *pratyaya* (缘) cannot be established as a self-natured entity.

Piṅgala extends the same logic to 十二因緣 (the Twelve Links of Dependent Origination, dvādaśāṅga pratītyasamutpāda) and to 增上緣 (the dominant condition, *adhipati-pratyaya*). He notes that all dharmas are "自無定性" — without fixed nature — and that the classic formula "是事有故是事有" ("because this exists, that exists") is offered in accommodation to ordinary conceptualization (隨順分別). It is *a way of speaking*, not a proof that the related dharmas possess any fixed, self-existent character.

The concluding verse: where 非缘 does its final work

The chapter gathers itself into a single, devastating verse:

「果不從緣生,不從非緣生,以果無有故,緣非緣亦無。」 "The fruit is not produced from conditions, nor from non-conditions; because the fruit is ungraspable, conditions and non-conditions are both ungraspable."

And Piṅgala's gloss on the second half is the most important sentence in this whole chapter for understanding 非缘:

「不從非緣生者,破緣故說非緣。實無非緣法,是故不從非緣生。若不從二生,是則無果。無果故,緣非緣亦無。」 "'Not produced from non-conditions' is said because *non-condition* is itself posited only in order to refute *condition*. In reality there is no *non-condition dharma*, and therefore one cannot be produced from it. If [the fruit] is not produced from either, then there is no fruit. Because there is no fruit, *condition* and *non-condition* are both ungraspable."

This is the heart of the matter. **非缘 is not an entity. It is a negating instrument (遮遣, *apavāda*). It is brought onto the stage for one purpose: to demonstrate that 缘 cannot sustain its own claim to self-nature. Once that demonstration is complete, 非缘 walks off the stage too.** The final scene is empty: no fruit, no condition, no non-condition.

The chapter seals this with one more elegant turn:

「若眾緣和合,是中無果者;是則眾因緣,與非因緣同。」 "If in the assembly of conditions there is no fruit, then the so-called causes-and-conditions are no different from non-causes-and-non-conditions."

This is not to say "nothing matters" or "everything is arbitrary." It is to say that the *distinction* between a cause-condition (因缘, *hetu-pratyaya*) and a non-cause-condition (非因缘) was being held up by our confidence that we knew where the fruit was. When that confidence collapses, the distinction collapses with it — not because reality has become chaotic, but because the distinction was always a matter of conceptual designation.

The place of 非缘 in the larger path

It helps to see where this argument sits in the overall structure of Buddhist liberation.

- Dependent Origination (缘起, pratītyasamutpāda) is the Buddha's teaching that phenomena arise in dependence on conditions. It is the central, celebrated doctrine. - Emptiness (空, śūnyatā) is the further insight, articulated above all by Nāgārjuna, that dependent origination means *nothing arises with self-nature* — nothing has an independent, fixed essence. - 非缘 (apratyaya) is the surgical tool used inside that insight. It does not deny dependent origination; that would be 断见 (uccheda-dṛṣṭi), the nihilistic view. It interrogates our *grasp* on conditions as if they were self-existing causes. That grasp is the 常见 (śāśvata-dṛṣṭi), the eternalistic view.

So 非缘 lives in the narrow, precise zone between denying causation (nihilism) and reifying causation (eternalism). It is the conceptual scalpel that lets the Middle Way (中道, madhyamā pratipad) operate without tipping into either side.

Nāgārjuna's own famous verse — "Whatever is dependently originated, that I declare to be empty" (眾因緣生法,我說即是空) — sits exactly here. 非缘 is one of the specific technical moves that make that verse true without making it nihilistic.


Walking It Through in Daily Life

Let's take the conceptual architecture above — the post-hoc naming of conditions, the three-fold negation of the fruit, the collapse of the cause/non-cause boundary — and walk it through a few scenes you will recognize.

Scene 1: The argument with your partner

You had an argument. Afterward, you think: *"The cause was that comment he made at dinner."* The comment, in your mind, is now *the condition*. Before dinner, was that comment already a condition of the fight? Of course not — it was just a sentence. We only named it "the cause" once the fight had already happened. This is Piṅgala's pot: the cause-label is bestowed after the fruit. It is 施設 (post-hoc designation).

Now let's run the three-fold check on "the comment":

- *先有*: Was the fight already sitting inside the comment, waiting? If so, every time he said anything similar, the fight would have to happen — clearly it doesn't. So the fight was not pre-existing in the comment. - *先無*: Was the fight wholly absent before dinner, and then appeared out of nothing? But you also feel it wasn't nothing — your body had been tenser for two days, sleep was bad, work was piling up. The fight feels overdetermined, not conjured from a void. So the "wholly absent" reading doesn't capture what you experienced either. - *兩者並存*: Were the fight both pre-existing and absent? This is the mental move of saying "it was latent." But "latent" is just a softer way of smuggling 先有 back in — you're positing a hidden version of the fight sitting somewhere, waiting to emerge.

Now here's where 非缘 appears. You might next say, *"OK, then the real cause was NOT the comment — the real cause was my tiredness."* You have just invented *non-condition* (apratyaya). You have moved the cause-label from one place to another in order to preserve the *category* of cause. But Piṅgala's point is that this move does not save the category — it just demonstrates how thoroughly you need a category to be saved. There was no self-natured "tiredness" sitting in your body producing a self-natured "fight." There was a tangle (众缘和合, the assembly of conditions): the comment, the tiredness, the history, the sleep debt, the hunger, the tone of voice. And if you can't locate the fight in any one of them — neither pre-existing nor absent nor both — then the tidy binary of *cause / not-cause* quietly loses its grip. The 因缘 (cause-condition) and 非因缘 (non-cause-condition) become indistinguishable, not because reality is mush, but because the distinction was always a conceptual overlay.

The practical upshot is not "nothing caused anything" but rather: *you don't have to pick one*. The reification of cause is what makes the argument continue — because once you've named "the cause," you also implicitly named who's to blame. Releasing the grip on that reification can, paradoxically, make the conversation easier. You can still see what happened. You just don't have to nail it to a cross.

Scene 2: The late-night phone and the algorithm

You're scrolling at 1 a.m., and afterward you think, *"The algorithm made me do it."* The algorithm is now *the condition* — your non-condition candidate would be "my own willpower" or "real me." This is a contemporary case of the same move. The screen shows you content; afterward you call it the cause. Before the next scroll session, was the algorithm already a cause of your insomnia? It was just code.

Now run the three-fold check on the algorithm-as-cause:

- *先有*: Was the 2 a.m. wakefulness already written into the recommendation algorithm? In a literal sense, *somewhat* — the algorithm was designed to maximize engagement, and engagement includes late-night use. So there's something here that looks like 先有. - *But here's the catch*: the algorithm doesn't operate in a vacuum. It is conditioned by your prior clicks, your data, the time of day, your current mood, the phone's battery. The "algorithm-as-cause" was never sitting there as a sealed object. It was already a tangle (众缘和合). - *先無*: But the late-night wakefulness is also not pure nothing. Your nervous system has states. You weren't equally likely to scroll at 1 p.m. as at 1 a.m. — though sometimes you do scroll at 1 p.m., so even "the time" isn't a sealed cause.

Now the 非缘 move would say: *"OK, so the cause wasn't the algorithm — the cause was my anxiety."* Same structure. You've swapped one cause for another to preserve the *category*. The Madhyamaka reading would not deny that scrolling happened, that algorithms shape behavior, or that anxiety is real. It would simply point out that *pratyaya* (condition) is not the kind of thing that can be definitively pinned down, and that the oscillation between "it was the algorithm" and "it was me" is itself a symptom of the reification.

This is also where contemporary brain science and AI discussions can offer a useful mirror, without claiming they prove the dharma. Modern reinforcement-learning models describe behavior as emerging from the interaction of policies, reward signals, environmental affordances, and prior states — *not* from a single identifiable "cause." Causation in these systems is distributed, context-dependent, and counterfactually fragile (change one small input and the entire trajectory shifts). Cognitive science has long abandoned the idea that there is "a place" in the brain where a decision lives. This distributed, non-local picture of causation in complex systems is strikingly congenial to what the Madhyamaka analysis is pointing at — though we should be careful: the Madhyamaka is not making a neuroscientific claim; it is making an ontological one. Neuroscience can describe how causal attribution operates; it cannot, by itself, settle the question of whether causation has self-nature.

Scene 3: The job offer and the "right path"

You are weighing whether to take a job offer. You think: *"The right conditions lined up — this is the condition for my flourishing."* You have named the offer as 缘. Months later, if the job doesn't work out, you may say, *"That wasn't the right condition after all — the real condition would have been the other offer I turned down."* That "real condition" is your 非缘 candidate.

The Madhyamaka move is not to tell you that choices don't matter. It is to notice how thoroughly we depend on the *concept* of "the right condition" to feel that our lives have direction. When the right-condition object is taken away, we instantly posit it elsewhere — sometimes in the past (a missed chance), sometimes in the future (a hoped-for opening). The named condition and the named non-condition are both facilities we use to keep the *category* of "the right path" intact.

What 非缘 exposes is that the category itself is what needs examining — not in order to paralyze you, but so that you can act *without the underlying terror that you must have picked the right cause for your life to be valid*.

Where the mapping most often goes wrong

Three common misreadings of the daily-life application:

1. Mapping 非缘 onto "the algorithm / external cause" alone. In the argument above, the algorithm was offered as the *condition*, and your "real willpower" as the *non-condition*. But the analysis targets *both* the algorithm and the willpower — both are facilities of reification. Modern people often feel they are being very sophisticated when they say "the algorithm did it," and imagine this is the Madhyamaka view. It usually isn't — it is just swapping one condition for another.

2. Mapping the three-fold negation onto a single cause. People often hear "the fruit isn't in the cause" and think this means *some other cause* must be the fruit's location. But the negation is not pointing toward a better candidate; it is pointing at the *operation of positing candidates at all*.

3. Treating 非缘 as a synonym for "nihilism about causation." This is the error the text most carefully avoids. Non-condition is not the absence of condition; it is the *unavailability of condition as a self-existent category*. This is the precise distinction Nāgārjuna is trying to hold.


Why Contemporary People Need This

There are at least three pressures that make this ancient analysis newly urgent.

First, the cult of attribution. Contemporary life runs on attribution. We are surrounded by dashboards, attribution models, postmortems, root-cause analyses, therapy frameworks that hunt for "the origin" of a pattern, news cycles that demand "who is to blame." In every one of these, we operate on the implicit conviction that there is *a thing called the cause* and that finding it is the goal. The Madhyamaka analysis suggests that this confidence is doing a lot of unexamined work — and that the *category of cause* is what most needs examining, not just this or that candidate cause.

Second, the cognitive overload of distributed causation. Our actual lived environment is full of complex, distributed causal systems — social-media feedback loops, market dynamics, climate cascades, neurochemistry, interpersonal histories. The naive view of "a cause" is increasingly difficult to defend empirically even before we get to philosophy. Yet people keep reaching for it, because the alternative feels like vertigo. 非缘 offers a way to *hold the actual complexity* without falling into either rigid determinism ("the algorithm made me") or its reactive counterpart ("I made me, alone, by sheer will"). Both are reifications; both can be loosened without denying that things happen.

Third, the ethical and existential payoff. When we stop trying to nail causation down to a single, blame-worthy, praise-worthy *thing*, something relaxes. We can still see what contributed. We can still act skillfully. We can still hold people (including ourselves) responsible in the conventional sense — because responsibility is a *prajñapti*, a workable designation within the world of dependent origination, and the Madhyamaka never asks us to abandon that. What we release is the underlying conviction that the conventional designation corresponds to a fixed, self-existent *cause* in the world. That release is, practically, a form of freedom.


Common Misreadings and Clarifications

Misreading 1: 非缘 means "uncaused" or "anti-cause"

The most common Western misreading is to translate *apratyaya* as "anti-cause" or "uncaused" and so place it in the lineage of Nietzsche or of certain existentialist critiques of causation. But Piṅgala is explicit: "實無非緣法" — *there is in reality no non-condition dharma*. 非缘 is not a competing metaphysical entity. It is a negating instrument whose entire work is to expose that 缘 cannot sustain itself as an entity. Reading it as "uncaused" mistakes the scalpel for a position.

Misreading 2: 非缘 entails nihilism about karma or causation

Because 非缘 dismantles the reification of 缘, some readers assume the Madhyamaka is denying karma, moral responsibility, or practical causation. This is the 断见 (nihilistic view) the tradition most carefully avoids. The collapse of *pratyaya as self-natured entity* does not collapse *pratyaya as conventionally functional designation*. Karma works within dependent origination; dependent origination is empty of self-nature; non-emptiness of self-nature and emptiness of self-nature are not the same thing. 非缘 is on the side of the second, not on the side of denying the first. As Nāgārjuna famously frames it, the Buddha's teaching of dependent origination is precisely what allows him to refute both eternalism and nihilism — and 非缘 is one of the technical tools that does this.

Misreading 3: 非缘 is "the opposite of 缘"

The two are sometimes presented as a symmetrical pair: 缘 = cause, 非缘 = non-cause, like day and night. The text resists this. *Non-condition* exists *only in relation to* *condition*, and only as a device for undoing the reification of *condition*. There is no independent *apratyaya* that could be opposed to an independent *pratyaya*. The pair is asymmetric on purpose: 非缘 is the shadow thrown by the interrogation of 缘, and when the interrogation is complete, the shadow has no substance either.

Misreading 4: Confusing 缘 (pratyaya) with 因 (cause) in the Aristotelian sense

Western readers often map 缘 onto "cause" in the Greek or modern sense, and then non-condition onto "non-cause." But 因缘 (hetu-pratyaya) in Buddhist philosophy is a wider, more relational category than the Western notion of efficient cause. It includes conditions that are not causes in the strict sense — the *adhipati-pratyaya* (dominant condition), the *anantara-pratyaya* (immediately preceding condition), and the various links of *pratītyasamutpāda*. The Madhyamaka analysis of 缘 is therefore not just about "causes" but about the whole network of conditioning relations through which phenomena appear. 非缘 destabilizes that whole network as a self-existent object — not just "efficient causes."

Misreading 5: Treating 非缘 as a "deeper" cause or hidden mechanism

Some readers, especially those influenced by depth-psychology framings, hear 非缘 and imagine it as a *deeper, more hidden* condition — the "real" condition behind the obvious one. This is precisely the move the text refuses. 非缘 is not a deeper cause. It is the dissolution of the depth-model of causation. There is no hidden layer being revealed; there is the undoing of the conviction that any layer, surface or hidden, contains a self-existent cause.

Misreading 6: Treating this as pure word-game or "just philosophy"

It is tempting to file 非缘 under "academic Madhyamaka" and assume it has no bearing on lived experience. But the whole structure of the argument — the post-hoc naming of conditions, the three-fold failure of the fruit to be located in the condition, the collapse of the 因缘 / 非因缘 boundary — maps onto the daily-life scenes above with uncomfortable precision. The text is not asking us to play a language game. It is asking us to notice how thoroughly our suffering depends on the reification of conditions, and to experience what relaxes when that reification loosens.


Closing Note

非缘 is, in the end, a strange and almost paradoxical concept: it is most itself when it has disappeared. It is the philosophical equivalent of a ladder that you use to climb to a place from which the ladder is no longer needed. Piṅgala's line — "破緣故說非緣。實無非緣法" — is the precise statement of this: non-condition is said in order to refute condition; in reality, there is no non-condition dharma. The chapter does not leave you holding a new thing called 非缘. It leaves you holding *less*: less confidence in the reified category of cause, less grip on the demand that the world hand you *the* cause of what happened, and — if the analysis has done its work — a slightly lighter way of walking through a world in which things genuinely do arise in dependence on conditions, but in which no condition is, has ever been, or could ever be, a self-existent thing.

Canonical EntryAI-generated

1. 定义与核心要义

“非缘”(apratyaya)在《中論·破因緣品》中,主要是与“缘”相对而说的遮遣性概念。它并不指一种独立存在、能够与“缘”并列的法,也不是另一类可以产生果的原因;其提出,是为了反问并破除对“缘”具有确定自性的执著。青目释明确说:“破緣故說非緣。實無非緣法。” 因而,从本品的论证次第看,“非缘”虽在言说中与“缘”相对,但这种对立只是随破随立的设施;当“缘”不可得时,“非缘”也不可能作为实有范畴保留下来。

其核心要义可概括为:若果与缘之间的关系无法被确定为果先有、先无或有无并存,则所谓“缘”无从成立;而“非缘”只是因破斥“缘”而暂时说出的反面名称。既然果不从缘生,也不从非缘生,最终便是果、缘与非缘皆不可得,而非另立一种“非缘生”的理论。

2. 主要阐述

首先,本品从“缘”如何得名的问题切入。设难者提出:“因是法生果,是法名為緣;若是果未生,何不名非緣?” 这一反问指出:如果某法必须在果已经由它产生之后才被称为“缘”,那么在果尚未产生时,它似乎尚不具有“缘”的资格,因而也可能被称为“非缘”。问题的重点不在于确立“非缘”的实体,而在于揭示“缘”的名称依赖于果的出现,并无预先固定的性质。

青目以瓶为例说明,水、土等之所以被称为瓶的缘,是因为人们见到瓶从这些条件而生,遂依所见安立其名;这种称名属于因果出现之后的设施。 但果未生时,也不能因此断定水、土等就是具有确定性质的“非缘”。所以,无论预先将某法定为缘,还是反过来定为非缘,都会把依待而立的名称误认为法自身固有的规定。

其次,本品从果在缘中究竟以何种方式存在展开否定:“若果非有生,亦復非無生,亦非有無生,何得言有緣?” 若说果在缘中先已有,则再生没有意义;若说果先前全无,则“无”如何由缘转成确定的果仍不能成立;若说果既有且无,又同时包含前两者的问题。果既不能被规定为从这三种情形而生,作为生果条件的“缘”也就无从获得确定性。

这一论证亦涉及十二因缘及增上缘。青目释指出,诸法“自無定性”,故“無有有相”;经中所说“是事有故是事有”,是随顺凡夫分别而作的言说,并不表示相关诸法具有固定不变的有性。 因此,因缘关系虽可在分别和言说中建立,却不能据此证明“缘”是具有自性的实法。

本品最后以偈颂总收:“果不從緣生,不從非緣生,以果無有故,緣非緣亦無。” 此处同时否定从缘生与从非缘生。青目进一步解释,“不从非缘生”是因为“破缘故说非缘”,事实上并没有一种“非缘法”可供果从中产生;果既不从二者而生,便无可得之果,果不可得,缘与非缘亦皆不可得。 因而,“非缘”只完成破除“缘”之定执的作用,不能被转化为新的生果根据。

此外,本论又从众缘和合中有无果的问题指出:“若眾緣和合,是中無果者;是則眾因緣,與非因緣同。” 如果众缘和合之中并没有果,那么这些所谓因缘便不能凭借“其中有果”而区别于非因缘。此说进一步动摇因缘与非因缘的固定界限,显示二者之别同样依赖于对果及其生起的分别。

3. 不同部类与译本的表述差异

现有材料仅列中观部《中論》(《中論》)及青目释,未提供其他部类经典或本论异译本,因而不能据此列举跨部类、跨译本的术语分歧。就本论内部而言,基本对举是“緣”与“非緣”;讨论具体因果关系时,又使用“因緣”“眾因緣”与“非因緣”。 论及缘的类别或教说时,材料还出现“十二因緣”“增上緣”“次第緣”等名称,其中关于诸法无定性的说明涉及十二因缘及增上缘。

“非缘”与“非因缘”在本论中的出现方式略有不同:“非緣”主要用于“果不從非緣生”以及“緣非緣亦無”的成对遮遣;“非因緣”则见于众因缘与非因缘相同的比较。现有材料未见“非缘”的其他异名,也未显示同经异译以另一术语对应 apratyaya,故不宜增列原文未载的译名。

4. 与相关概念的关系

“缘”是“非缘”直接破斥和依待的对象。没有对“缘”的定性,就不会相对地提出“非缘”;而“缘”一旦被证明无固定自性,“非缘”也随之失去成立的依据。因此,两者并不是两个各有自体的相反事物。

“果”是缘与非缘能否安立的关键。法因生果而被称为缘,故果未生时便引出“何不名非缘”的诘问。 进一步说,果既不能被确定为有生、无生或有无生,缘便不可得;果若不可得,则缘与非缘皆不可得。

“因缘”与“非因缘”的关系,是“缘”与“非缘”关系的另一种表述角度。众缘和合中若无果,众因缘即无法凭借果来显示其因缘性,因而被说成“与非因缘同”。 这并非把因缘断定为另一种实有的非因缘,而是取消二者固定不变的界线。

“十二因缘”“增上缘”等,则属于本品所检视的缘法言说。材料指出,相关表述建立在诸法无定性之上;“是事有故是事有”可以随顺分别而说,却不能据此建立具有自性的“有相”。

5. 代表性原文引用

“因是法生果,是法名為緣;若是果未生,何不名非緣?”

“若果非有生,亦復非無生,亦非有無生,何得言有緣?”

“果不從緣生,不從非緣生,以果無有故,緣非緣亦無。”

“不從非緣生者,破緣故說非緣。實無非緣法,是故不從非緣生。若不從二生,是則無果。無果故,緣非緣亦無。”

“若眾緣和合,是中無果者;是則眾因緣,與非因緣同。”

中論T1564 · 中觀部

《中論》對「非緣」的論述,主要透過破斥緣的實在性來顯示非緣亦無自性,並未將非緣視為與緣並列的另一類實在法。

一、質疑緣與非緣的分判 論文以反問揭示緣的定義並無決定性:「因是法生果,是法名為緣;若是果未生,何不名非緣?」既然某法能生果才被稱為緣,那麼果尚未生時,何不徑直將水土等稱為非緣?青目釋文進一步說明,緣之所以被稱為緣,端因後來見有果從之而生;若果未生,水土等根本無由被安立為緣。緣的成立完全依賴果的後起,而非緣的成立則預設果的未生,這個分判本身已暴露緣的無決定性。

二、緣中無果,緣義不成 論文承接此意,在緣中觀察有無果體:「緣中先非有果、非無果。若先有果,不名為緣,果先有故。若先無果,亦不名為緣,不生餘物故。」緣既不能先有果亦不能先無果,緣的自性便不可得,由此非緣亦無從安立。

三、以無自性遮遣緣與非緣 核心論證在於:果從眾緣生,而眾緣本無自性;無自性即無法,無法即不能生,故果不從緣生。同段論文又云:「不從非緣生者,破緣故說非緣。實無非緣法,是故不從非緣生。」這是《中論》處理非緣一詞最關鍵的語句——非緣並非指異於緣的另一實在之物,而是為了破斥緣的實在性所施設的遮遣語。實際上並無實在的非緣法,故亦談不上從非緣生。若果不從緣生、不從非緣生,則無果可說;無果故,緣與非緣俱泯。

四、因緣非因緣等同 又一偈總結此義:「若眾緣和合,是中無果者;是則眾因緣,與非因緣同。」若眾因緣和合而中無果,則因緣與非因緣無有差別,從反面顯示非緣並非獨立存在之法,而是緣之實在被破除後所顯的等同境界。

此外,論文亦順帶論及次第緣與增上緣皆不可得,皆因諸法從眾緣生、無有定性,緣既不成立,依緣而施設的非緣亦無從安立。

總之,《中論》以「非緣」一詞,僅作為破遣緣的遮破之語,並未賦予其獨立的實在義;非緣之所以被說,正是為了顯示緣與非緣俱畢竟空。

十二門論T1568 · 中觀部

《十二門論》對「非緣」之論述,係由破「緣能生果」之執而顯發,可分三層:

一、先列四緣之名,逐一觀察果之所在。經中立「因緣、次第緣、緣緣、增上緣」四緣:因緣者,隨所從生法,已從生、今從生、當從生;次第緣者,前法已滅次第生;緣緣者,隨所念法,若起身業、口業、心心數法,是名緣緣;增上緣者,以有此法故彼法得生。此處「緣緣」一詞,與常見之「所緣緣」用詞有別,本經未加「所」字而徑稱「緣緣」,當留意此特別譯名。經云「如是四緣,皆因中無果」,又云「一一中無、和合中亦無」,以總破緣中有果。

二、以因中求果、緣中求果之雙向推求,否定緣能生果。若因中有果,應離諸緣而有果,而實離緣無果;若緣中有果,應離因而有果,而實離因無果;若於緣及因有果,以理推求應可得而實不可得,故二處俱無。是故經結云「云何得言果從緣生」,正式逼出詰問。

三、由是進一步提出「非緣」之難,以顯緣生之無據。經云:「若果緣中無,而從緣中出,是果何不從非緣中而出?」意謂:若果本不存在於緣中,竟能從緣而生,則依同等道理,此果亦應能從非緣而生。既不能說非緣能生果,則言緣能生果便毫無正當性。此段開篇一句「諸法緣不成,何以故」,即為本段破斥之綱領。

整體而言,《十二門論》論「非緣」,並非主張非緣能生,而是以「若緣中無果猶可生果,則非緣亦應生果」之反詰,照出緣生說之顛倒;此以非緣顯緣生之過,乃本經獨到之論證側面,非另立非緣為一新生起因。
