A Contemporary ReadingAI-generated

There is a question most people never think to ask, but which sits underneath nearly every modern disagreement: *Where did this thing come from?* More specifically: *Did it come from somewhere else — from something genuinely outside it?*

The Buddhist philosophical tradition has a name for the assumption that yes, it came from somewhere else, from a separate "other" standing outside it and producing it. That name is 他生 (*parata-utpāda*, literally "other-production" or "arising-from-another"). It is one of the most quietly powerful ideas in the entire Buddhist critique of how we think about causation, identity, and responsibility.

In what follows, I want to do four things: explain what 他生 actually means in its classical setting, walk through it in contemporary life where it shows up disguised as something else, say why people living now especially need to know it, and then carefully separate what it actually says from the things it is commonly mistaken to say.


What This Concept Is Saying

The Four-Fold Frame

In the *Mūlamadhyamakakārikā* (《中論》, "Fundamental Verses of the Middle Way"), composed by Nāgārjuna (*Lóngshù*, 龍樹) and translated into Chinese by Kumārajīva (*Jiūmóluóshí*, 鳩摩羅什) as Taishō text 1564, the question of how things arise is set up as four competing views:

1. **自生 (*sva-utpāda*) — arising from itself 2. 他生 (*para-utpāda*) — arising from another 3. 共生 (*dvaya-utpāda*) — arising from both self and other together 4. 無因生 (*ahetu-utpāda*)** — arising without cause

The classical summary verse is one of the most quoted in Buddhist philosophy:

「諸法不自生,亦不從他生,不共不無因,是故知無生。」 *Things do not arise from themselves, nor from another, nor from both, nor without cause; therefore we know there is no arising.*

A second formulation says essentially the same thing in a different shape:

「法不從自生,亦不從他生,不從自他生,云何而有生。」 *A dharma does not arise from itself, does not arise from another, does not arise from self-and-other — how could there be arising?*

The conclusion — 無生 (*anutpāda*, "un-arising" or "no-arising") — is what the whole analysis builds toward. But 無生 is not a fifth option sitting alongside the four; it is the *result* of seeing that none of the four work.

So why does this matter for someone not trained in Buddhist philosophy? Because the question "did this come from something else?" is not just a metaphysical puzzle. It is the grammar behind how we explain our own suffering, our relationships, our identities, our anger, our depression, our success. Almost every modern attribution of cause is, when you look closely, some version of 他生.

The Argument Against 他生 Specifically

The Mūlamadhyamakakārikā dismantles 他生 through five interlocking arguments. Each is worth knowing in its own right; together they show why "it came from somewhere else" — taken in the strong form — does not actually hold up.

1. Self and other are mutually dependent (相待).

The word "other" (他) is not a freestanding designation. It only makes sense relative to a "self" (自). The text puts it sharply:

「自無故,他亦無。何以故?有自故有他。」 *When there is no self, there is no other. Why? Because "other" exists only because "self" exists.*

If the "self" (the supposed product) cannot be established as something with independent nature, then the "other" (the supposed producer) cannot be established either. They rise and fall together.

There is a second version of this same point that is even sharper:

「若法未生則亦無他,無他故不得言從他生。」 *If a dharma has not yet arisen, then there is no "other" for it; without an "other," one cannot say it arises from another.*

Notice what this does to the usual order of explanation. We say: "this thing exists, and it came from something else." But to say it came from something else, that "else" must already be in place to come *from*. The analysis flips the order: the very existence of the supposed product is what allows us to designate its producer. So the producer is not producing anything — the producer is being constituted by our act of designating it.

2. "Other-ness" is "self-ness" from the other side.

This is the argument that confuses people most, and also the most elegant:

「他性於他亦是自性,亦從眾緣生相待故,亦無。無故,云何言諸法從他性生?他性亦是自性故。」 *What is "other-nature" for another is itself "self-nature," and likewise arises from conditions and is dependent; it too is without self-nature. Without it, how can one say things arise from other-nature? Because other-nature is itself self-nature.*

Walk this through slowly. I look at a tree and call the tree "the other" relative to me. But the tree, from the tree's own perspective, is "self." What I have labeled "the other" is, viewed from its own side, just another "self." So if I am using 他生 to explain how the tree causes some change in me, I am in fact relying on a category that, the moment I flip perspectives, becomes 自生. I have not escaped the problem; I have just renamed it.

This is the move that distinguishes Buddhist philosophy from a vague "everything is connected" intuition. It is precise: the alternative to self-nature is not "everything is connected by an Other," but the structural observation that the categories themselves are position-dependent.

3. "Arising" itself has no self-existence yet.

The third argument goes upstream, to the verb itself:

「生未有故,不應從他生。是生無故無自體,自體無故他亦無。」 *Because arising has not yet been established, [a thing] should not be said to arise from another. This arising, without [self-nature], has no self-existence; without self-existence, the "other" is also not established.*

The sutra offers a striking image: just as a fingertip cannot bend around and touch itself, the act of arising cannot arise from itself.

What this argument is doing: even granting (for the sake of discussion) that there is some "other" out there, the very process of "arising" has no fixed self-nature that the "other" could be said to produce. And if "arising" lacks self-nature, then the "other" we were going to use as the producer also lacks the kind of stability required to be a producer. The supposed ground of explanation turns out to need explanation itself.

4. The infinite regress of "producing production."

This is perhaps the most practically visible argument. Suppose someone insists that yes, there is arising, but it needs another "producing" to produce it. Call the original arising 本生 (*muṣmī-utpāda*, the original arising) and the supposed producer 生生 (*utpādaka-utpāda*, producing-arising). The text asks:

「若生生時能生彼,是生誰復能生。」 *If, at the moment of producing-arising, it can produce that [original arising], who then produces that producing?*

And:

「若生更有生,生則無窮。」 *If arising needs further arising, there is no end to arising.*

The regress can also be circular rather than linear:

「是生生從本生生,云何能生本生。」 *If this producing-arising arises from original arising, how can it produce the original arising?*

And:

「若言生時生,是能有所生;何得更有生,而能生是生。」 *If one says that at the time of arising there is arising, and this can produce something, how can there be yet another arising that produces this arising?*

Any attempt to "save" arising by positing another arising as its cause runs into either a circle (each producing the other) or an infinite chain (each arising needs a further arising). Neither delivers what we wanted — a stable, grounded account of how this thing came to be. This is the regress he生 smuggles in every time we say "but what caused *that*?"

5. No findable fruit in the confluence of conditions.

The final argument is the simplest:

「若物無自性,是物終不生。」 *If a thing has no self-nature, then this thing never ultimately arises.*

In the actual flow of causes and conditions, when you look closely, no fixed, independent "effect" or "fruit" can be located as the thing that has arisen. The image in many commentaries is of trying to grab butter from a flame — the harder you reach, the more it eludes you. So even within ordinary causal analysis, the "thing that arose" cannot be pinned down as an independent entity that the "other" produced. The candle flame does produce melting butter, and the butter does melt — but no fixed "butter-with-self-nature" is being deposited onto a fixed "self-existing plate."

Where This Sits in the Whole Path

It is essential to see what the *Mūlamadhyamakakārikā* is doing here. It is *not* trying to deny that things appear, that conditions produce outcomes, or that causes matter. The whole Buddhist path — karma, the four noble truths, dependent origination itself — presupposes that conditions matter.

What is being examined is whether the things we use to explain — the causes, the effects, the producers — can be posited as having fixed, independent self-nature (自性, *svabhāva*). When that reification is seen through, the entire causal framework continues to function — fire still burns, parents still shape children, trauma still leaves marks — but without the metaphysical assumption that there are "self-existing things" being handed from one to another.

This is the move from 緣起 (*pratītyasamutpāda*, dependent origination: things arise in dependence) to 緣起性空 (*pratītyasamutpāda-śūnyatā*, dependent-arising is empty of self-nature). The first is the affirmation; the second is the precise characterization of what is being affirmed. 他生 collapses the moment we stop taking "the other" as a fixed independent producer. This is the same move later celebrated in the *Prajñāpāramitā Hṛdaya Sūtra* (《心經》, Heart Sutra): "照見五蘊皆空,度一切苦厄" — "having seen the five aggregates as empty, [one is freed from] all suffering." The five aggregates are present, functioning, experienced; what is seen through is their presumed self-existence — and the same is being done here to the "other" that supposedly produces them.


Life's Investigation: Walking Through It

Now the question becomes: where does this actually show up in a regular life? The classical arguments are precise; let's run them on the felt experience of an ordinary week.

Scenario 1: The genealogy of suffering.

You are sitting across from a friend, or perhaps in a therapist's office, and you say: "I am the way I am because of my parents." This is 他生 in everyday clothes. The "other" — parents, childhood, the family system — is being posited as the producer of "me" as I currently am.

Run Nāgārjuna's five checks on this:

- *Mutual dependence*: "Parents" only register as my parents relative to me. The very category "my parents" presupposes the "me" that supposedly came from them. - *Other-ness is self-ness from the other side*: My parents, from their own perspective, are not primarily "my parents." They are themselves — with their own childhoods, their own suffering, their own conditioning. The thing I have labeled "the producer" is, viewed from inside, just another "self" with its own lineage of suffering. - *Arising has no self-nature*: Even granting that parents shaped me, the "me" that supposedly arose has no fixed self-existence independent of the very conditions (memory, interpretation, current relationships) we are using to explain it. - *Regress*: If my parents shaped me because of *their* parents, and theirs because of *theirs*, and theirs because of historical conditions, and historical conditions because of further conditions... we have the infinite regress of 生生. - *No findable fruit*: When I look closely at "the way I am," I cannot locate a single fixed thing that was cleanly "produced" and is now sitting inside me. Patterns are real. Influences are real. But no fixed "self" was deposited by a fixed "other."

This does not mean "your parents had nothing to do with it." It means the *form* of the explanation — a producer producing a product with self-nature — is what breaks down. The influences continue to operate; what fails is the reification of both "them" and "you" as independent entities in clean producer-product relation.

Scenario 2: The infinite regress of justification.

You are in a meeting, or a family argument, or an online thread. Someone asks why a decision was made badly. The first person blames the second; the second blames the third; the third blames the system; the system was designed by someone; that someone was trained by someone else...

This is the 生生 regress in plain view. The standard move is to keep finding another "other" to explain the previous "other." The 他生 analysis suggests the regress is built into the assumption that causation requires finding a producer outside the produced. Each new "other" needs its own "other." The chain has no natural stopping point because the form of the question guarantees an endless answer.

Scenario 3: The moment of anger.

You feel a flare of anger at your partner, your child, a stranger on the sidewalk. The automatic interpretation: "They made me angry. They are the cause of this feeling." This is pure 他生 — the "other" is being installed as the producer of an emotion that arises with self-nature in "me."

The classical analysis here is not "you shouldn't feel anger." It is: the "they" that supposedly produced your anger is itself constituted by your interpretation, your expectations, the relational history, your current state — none of which has the fixed self-nature that would let it stand as an independent producer. The anger is occurring. The conditions are real. But no self-existing "they" is depositing a self-existing "anger" into a self-existing "me."

This is where the philosophical analysis lands closest to actual felt experience. The "other" that supposedly made me angry is rarely as solid as the anger suggests. If you pause for even a few seconds, the anger is there, but the producer-as-fixed-entity dissolves almost immediately.

Scenario 4: The First Cause temptation.

You are reasoning about origins — of the universe, of consciousness, of moral order. The natural move is to posit a foundational "other": a First Cause, an unmoved mover, a source that itself does not require a source. This is 他生 at its most ambitious: everything comes from *this one Other*.

The *Mūlamadhyamakakārikā* does not refute this by proving there is no cause. It shows that the category "First Cause" is internally unstable — it is "other" only relative to what it is supposed to produce, and declaring one link "foundational" without further inquiry is not a refutation of the regress, only a refusal to follow it. The 缘起 framing says: there are conditions all the way through; there is no place where a self-existing "other" stands alone outside the chain producing the chain.

Scenario 5: The social-media comparison machine.

You scroll and see someone living a life that looks fuller than yours. A voice says: "Their life is better; that's why I feel small." Here, the "other" — that curated online presence — is doing causal work on your self-feeling.

But what is that "other"? It is a slice of a person chosen by an algorithm responding to your attention patterns. The "they" that supposedly produces your "smallness" is not a stable person; it is a relation between attention, design, lighting, and your own comparison-habit. Calling it a producer already concedes too much. The 他生 analysis is sharpest here: most of the "others" we install as producers of our inner states are not stable, independent entities at all. They are phenomena constituted by the very processes we are trying to use them to explain.


Why Contemporary People Need This

There are at least three reasons this ancient argument is unusually relevant now.

First, we live in a hyper-attributional culture.

Modern discourse — psychological, political, social — runs on attribution. We are constantly being told (and telling ourselves) that X is the cause of Y: genes cause depression, childhood causes patterns, culture causes behavior, the economy causes inequality, the algorithm causes radicalization, the partner causes the divorce.

The 他生 analysis does not deny these correlations. It asks whether the *relata* — "genes," "depression," "childhood," "behavior," "the algorithm" — are the kind of self-existing things that can stand in clean producer-product relations. In most cases, they are not. Genes are not static programs; depression is not a fixed entity deposited into a person; "the algorithm" is itself shaped by the attention it shapes; the partner is shaped by the very marriage that is supposedly being explained by them.

When we treat these as fixed producers producing fixed products, we get both bad explanations and bad interventions. You cannot meaningfully address something you have already reified into a producer.

Second, it offers a non-reactionary response to the question of agency.

One common reading of 他生-denial is: "So nothing is really anyone's fault. We are all just products." That is not what is being said. If "the boss" did not produce "my resignation" as a fixed producer of a fixed product, this does not mean the resignation happened without causes. It means the chain of conditions — including my own formation, including the boss's actions, including the cultural moment — is co-constituted in ways that resist the producer-product grammar.

This matters because the producer-product grammar produces both excessive blame ("They ruined me") and excessive denial ("Nothing to do with me"). The classical view opens a third space: responsibility without reification. Conditions are honored, causation is acknowledged, but neither "I" nor "they" are taken as fixed entities standing outside the process in clean causal relation.

This is closer to how skillful action actually feels in practice: I am not the unmoved source of my choices, nor am I the passive end-product of everything that happened to me. I am part of an unfolding, and the unfolding includes me.

Third, it converges with — but is not identical to — certain moves in contemporary science.

In physics, the notion of an external cause producing a local effect runs into trouble at the quantum level, where the observer and the observed cannot be cleanly separated. In biology, niche construction theory shows that organisms shape the environments that shape them — the "producer" and the "produced" are not cleanly separable. In complex systems theory, causation is often circular and distributed rather than linear and external. In neuroscience, the sense of a unified self doing the producing is increasingly hard to locate in any specific brain region.

The 他生 analysis anticipates these moves with a different vocabulary and a different aim. But — and this is important — it does *not* claim that science "proves" the Buddhist view. The convergences are suggestive, not conclusive. Science has its own open questions, its own unsettled debates, and its own limits of method. Holding the two together requires humility about both: the philosophical argument stands on its own terms, and the science is doing different work than the philosophy. To flatten that difference is to mistake a family resemblance for a proof.


Common Misreadings and Clarifications

Misreading 1: "This says nothing causes anything."

This is the most common error, and it should be met directly. The *Mūlamadhyamakakārikā* does not deny that in conventional terms (世俗諦, *saṃvṛti-satya*) causes produce effects. Fire burns. Parents raise children. Kindness matters. The whole of Buddhist soteriology — karma, the four noble truths, the path itself — depends on causation being real at the level of how we live.

What is denied is that causes, effects, and the act of producing have fixed, independent, self-existent nature. This is a more precise claim, and a much less dramatic one, than "nothing causes anything." Anyone who reads "no arising" as "no causation" has misunderstood what "self-nature" was doing in the original argument.

Misreading 2: "无生 means nothing exists."

無生 (*anutpāda*) does not mean "nothing happens." Things appear, change, cease — all the time. What is denied is arising *with self-nature* — arising in the form of a fixed entity being produced by another fixed entity. Phenomena arise dependently; what fails is the reification of the process into a transfer of independent substances.

A useful image: a wave arises on the ocean. Something happens — the wave is real, it has shape and motion. But the wave was not produced by some other wave that exists independently and was "transferred" into this one. It is a pattern of the whole water. To see the wave as a self-existing thing produced by a self-existing other wave is precisely the mistake.

Misreading 3: "This is just a metaphysical puzzle with no practical import."

It is a metaphysical puzzle, but not only one. Every time we reify "the other" — as the cause of our suffering, the source of our identity, the foundation of the universe — we are using the 他生 grammar. The classical analysis lands on the felt experience of anger, on the felt experience of being shaped, on the felt experience of being wronged. It is not separate from practice; it is part of how practice sees clearly.

If a teaching could not bear any weight on lived experience, the Buddha would not have bothered with it. The fact that this teaching sits at the heart of the *Mūlamadhyamakakārikā* is itself a signal about its practical weight.

Misreading 4: "This denies dependent origination (缘起)."

The opposite is the case. The whole point of refuting 他生 is to clear the ground for 缘起 — the actual, non-reified way things arise in dependence on conditions. 缘起 is the affirmation; 他生 is one of the misreadings of 缘起 that takes "dependent" and turns it into "produced by an independent other."

The relationship is captured in classical formulations: 缘起 (dependent arising) is the surface; 性空 (empty of self-nature) is what 缘起 actually consists in. The four-fold negation is the negative space around which 缘起 becomes visible. To read the negation as a denial of 缘起 is to mistake the framing for the picture.

Misreading 5: "Denying 他生 leads to nihilism or passivity."

This objection appears in the classical commentaries themselves, and the response is already embedded in the tradition: 缘起 is not passivity, because there is no fixed self to be passive or active in the first place. Action occurs within conditions; understanding the conditions clearly is itself part of skillful action.

Nihilism requires fixed existing things to be negated; once those aren't there, nihilism doesn't have its object either. The classical image is of someone who refuses to sit down because they have heard "there is no ground." The teaching is not "there is no ground" — it is "the ground is not what you thought it was." When you actually sit, you find the ground has been there the whole time, just not as a self-existing foundation.


The deepest thing the *Mūlamadhyamakakārikā* is doing with 他生 is not defeating an opponent but loosening a grip. The grip is the one we have on "the other" — the one that did this to me, the one I need to fix, the one I am waiting to be produced by, the one whose existence would explain everything. The analysis does not say the other is not there. It says the other is not the kind of thing that can be the producer of a self-existing product. From there, both the metaphysics and the lived relationship to being-caused-by have to be reorganized around the absence of that fixed producer.

This is why the teaching has lasted. It is not a doctrine to be agreed with. It is a habit of mind to be noticed, tested, and slowly released.

Canonical EntryAI-generated

一、定义与核心要义

「他生」(parata-utpāda)指一法从自身以外的「他者」或「他性」而生。在《中論》(中觀部·《中論》)中,他生并非独立讨论的生起方式,而是与自生、共生及无因生并列的四种生执之一。其总纲为:「诸法不自生,亦不从他生,不共不无因,是故知无生」;另一处又说:「法不从自生,亦不从他生,不从自他生,云何而有生」。因此,《中論》对他生的考察,旨在显示:若把能生的「他」及由他所生的「果」理解为各具自体的实有之法,则其关系不能成立;四种生起方式俱不可得,故说「无生」。

二、主要阐述

首先,《中論》从自、他的相待关系破他生。「他」并非不依任何条件而独立成立,而是相对于「自」才被称为他;故说:「自无故,他亦无。何以故?有自故有他」。当自性不可得时,与之相待而立的他性也无从成立。就尚未生起之法而言,经文又说:「若法未生则亦无他,无他故不得言从他生」。换言之,在所生之法尚未成立时,不能预先确立一个相对于它的「他」,再以此说明它由他而生。

其次,经文指出,他性转换立场后即是自性。某物相对于此法虽名为「他」,但对其自身而言仍是「自」。因此说:「他性于他亦是自性,亦从众缘生相待故,亦无。无故,云何言诸法从他性生?他性亦是自性故」。这里不仅说明自、他名称相待,也说明被称为自性或他性的诸法同样从众缘而起,不能获得不待因缘的固定自体。

再次,《中論》由「生」本身尚未成立来审察他生:「生未有故,不应从他生。是生无故无自体,自体无故他亦无」。若生尚未有,便不能把它说成从某个已经确定的他者生起;若生没有自体,则与它相对的他也不能成立。经文并以「指端不能自触」为喻,表明生不能反过来以自身完成对自身的生起。

又次,经文考察「生生」与「本生」的相互关系。若另立一种「生生」来产生本生,便须追问生生本身由谁而生:「若生生时能生彼,是生谁复能生」。若每一生又须另有一生使之生起,则成为「若生更有生,生则无穷」。若说生生由本生所生,却又说生生能生本生,二者便展转相待,故问:「是生生从本生生,云何能生本生」。同样,若主张在生时另有能生之生,经文诘问:「若言生时生,是能有所生;何得更有生,而能生是生」。这些论述共同显示,不能借助另一个外在的生来确立此生,否则或循环相待,或推至无穷。

最后,《中論》从因缘和合中果不可得的角度破他生。经文说:「若物无自性,是物终不生」。因、缘及其和合之中,若不能取得一个自性成立的果,就不能说有一个实在之果从实在的他缘中生出。因此,缘起并不等于承认诸法以固定自体从他法产生;所谓能生之他、所生之果及生起作用,均须接受自性是否可得的考察。

三、不同部类与译本的表述差异

现有材料仅列《中論》(中觀部·《中論》,龙树造、鸠摩罗什译),未提供其他部类经典或同经异译本,故不能据此列举跨部类或异译本之间的用词分歧。

就《中論》内部而言,相关表达有「他生」「从他生」及「从他性生」。「他生」是与自生、共生、无因生并列的概括名称;「从他生」着重表示从自身之外的他者生起;「从他性生」则把论题落在「他性」能否成立。与之相配的其余三句亦有不同表达:自生又作「从自生」,共生在偈中表述为「从自他生」,即自、他合说;无因生则作「无因」。这些差别属于同一译本中名词式与句式表达的变化,不宜据此另立不同义项。

四、与相关概念的关系

他生与自生相待而立:有自方可说他,自性不成,则他性亦不成。他生与共生的关系在于,共生即从自、他二者而生;当自与他分别不可得时,自他合生也失去成立依据。他生与无因生同属四句所破,但方向不同:他生主张依外在他者而生,无因生则不立原因;《中論》并列遮除二者,不因否定他生便转而承认无因生。

他生也与「生生」「本生」密切相关。另立生生作为本生的生因,仍属于以另一法说明此法之生;但二者若互相产生便成循环,若各须另一生则成无穷。他生最终又关联于无生:无生不是四句之外另立的一种生法,而是经由自生、他生、共生、无因生均不可成立而作的结论,故偈云「是故知无生」。

五、代表性原文引用

「诸法不自生,亦不从他生,不共不无因,是故知无生。」

「法不从自生,亦不从他生,不从自他生,云何而有生。」

「自无故,他亦无。何以故?有自故有他。」

「若法未生则亦无他,无他故不得言从他生。」

「他性于他亦是自性,亦从众缘生相待故,亦无。无故,云何言诸法从他性生?他性亦是自性故。」

「若生更有生,生则无穷。」

入中論善顯密意疏B0044 · 藏傳論典部

《入中論善顯密意疏》所說「他生」,並非泛指一法依另一法而生,而是指有自相、有自性之「他」能生有自相、有自性之果。正文特別辨明,「他生」二字不是聖教名言,而是餘宗名言;其所指為「有自相之他」。若承認此義,即須承認諸法有自性。因此,本論雖於名言中承認因果異體,卻不把這種異體稱為「他生」;所許者只是依眾緣而生,而非四邊生中的他生。

本論以頌文「若謂依他有他生,火燄亦應生黑闇,又應一切生一切,諸非能生他性同」總破他生。其理是:稻種與稻芽若因各具自性而成為「他」,那麼火、炭、麥種等不能生稻芽之物,也同樣是異於稻芽的自性之他。既然二者的「他性」相同,便無法僅憑此種他性區分能生與不能生,遂有火燄應生黑闇、一切因與非因應生一切果與非果的過失。

此處的關鍵不在否定一般差別,而在否定「由自相而成」且彼此無關係的他性。若因果是有自相之他,便不能成立彼此觀待的關係,也不能安立何者具足生果能力、何者不具足。故本論明說,所破不是凡許因果有異便犯過失,而是執其差異為自性成立;未善分辨所破範圍與緣起建立,才會誤解此理。

就前後因果而言,本論以種芽為例:如彌勒與鄔波笈多同時存在,方可互相觀待而見彼此為別法;種與芽卻不同時,種未壞時芽尚未有。因此,種子位中並無一個異於種子的自性之芽,也就不能成立種與芽是自性之他,更不能成立有自性的芽從種而生。這不是在名言中否定種芽有異,而是說二者沒有自性成立的他性。

對於同時因果,本論指出:若眼與眼識、俱有想等被計為有自性之能生因,而果在因位已經存在,則再生全無作用;若為免此過而說因位尚無果,又回到前後法不能成立自性之他的問題。因此,所謂他生僅有其名:或者有「他」而無自性之生,或者有生而無自性之他,皆不能成立自性他生。

本論亦處理世間現見之難。世人雖說「此兒是我生」或「此樹是我所栽」,其意只是父親置入兒身之因、栽種者殖下樹因,並非執種子與兒、樹種與樹為自相成立之他。因此,世俗中可說依此緣而有彼法生,卻仍不許四邊生。正文採用的術語區分十分明確:以「他生」專稱有自性之他所成之生;對名言中因緣生果,則稱「唯眾緣生」、「依此緣有此法生」或「緣起」,不稱為他生。

總結而言,本論由破自生、他生、共生、無因生四邊,成立諸法無自性生;但無自性生並非全無生。依此為緣而有彼果,世俗法即可成立;正因依緣生,故不是自性生。故其對「他生」的核心限定,是「有自性之他生有自性之果」,而不是一般名言中的因果異體或緣起生。

中論T1564 · 中觀部

《中論》對「他生」之論述,以否定「從他生」為核心要義,並由此推導出「無生」之結論。該論兼採偈頌標宗與青目釋文辨析兩種形式,從因緣觀與邏輯推演兩端破斥他生之執。

一、核心偈頌的表述。本經於破生品中以兩首偈頌明示四句之檢討。第一頌云:「諸法不自生,亦不從他生,不共不無因,是故知無生。」 第二頌云:「法不從自生,亦不從他生,不從自他生,云何而有生?」 兩頌均以「不從他生」為四句分別中之第二句,並以此為推導「無生」或「有生不可得」之依據。

二、他生不成立之根本理由:自與他相依。釋文云:「自無故,他亦無。何以故?有自故有他。」 此明「他」以「自」為前提,自體尚不可得,何況依自而立之他體;自他既然俱無,從他而生之說便失所依。

三、就「生」之本身而言,他生亦不可能。釋文云:「從他生亦不然。何以故?生未有故,不應從他生。是生無故無自體,自體無故他亦無,是故從他生亦不然。滅法亦如是,不自相滅、不他相滅。」 此先以「生未有」破「從他生」之可能,復以「自體無故他亦無」重申自他相依之理,並將此理推及於滅相。

四、他生與自生、共生同受遮遣。釋文指出:「若不從自生,亦不從他生,共生則有二過:自生、他生故。若無因而有萬物者,是則為常。是事不然。無因則無果,若無因有果者,布施持戒等應墮地獄、十惡五逆應當生天,以無因故。」 又總結云:「若三種不生,云何從法有法生?」 自生、他生、共生既皆不生,生相便了不可得。

術語方面,本經以「他生」、「從他生」並用,與「自生」、「共生」、「無因」對舉而立為四句分別;復以「自體」、「他」、「自他」之語助其推演。全論貫以因緣無自性之理,徹底遮遣他生之執。

百論T1569 · 中觀部

《百論》對「他生」(主張事物由自身之外的他者所生)之論述,乃以「吉事」是否真實存在為緣起,展開對生起本身的全面破斥。對方主張吉事自生,猶如鹽自性醎能令他物亦醎,又如燈自照亦能照他;內方則依「凡生法三種:自、他、共」之架構,逐一遮破。

關於「他生」的核心遮破,本卷以「自相無故,他相亦無」一句為樞紐:既然自相不可得,他相亦不能成立,故「亦不從他生」。此乃從自他相依之理否定他生——「他」之成立必有待於「自」之先立;若自不可得,則他亦不成。此一相依性論證,是本部否定他生的關鍵論理。

進一步以「無窮過」歸謬遮止他生:若從他生,則所賴之「他」本身亦需從更他之他而生,形成「生更有生」之無窮系列,故他生不可立。

至於「共生」(自他共),內方以「二俱過故」總破——自生、他生既皆被破,共生之兩支皆過,自然不能成立。本卷在結論處明言:「凡生法有三種:自、他、共。是三種中求不可得,是故無吉事」,顯示他生乃與自生、共生並列為破斥對象,三者皆「不可得」。

在破斥之喻方面,內方以鹽喻反破「吉能令他物吉」之執:鹽雖與他物和合,他物不因此而成鹽,因「鹽相鹽中住故」,猶如牛相不為馬相。此喻暗示他物本無鹽性,鹽不能以自身之性注入他物,故「他生」之理不成立。又以燈喻破自他俱照:燈與闇不並故,燈自無闇,「亦無能照」;能照與受照二相皆過,故燈不自照;所照之處亦無闇,故不能照他。此破顯示若燈自身無闇、無能照之性,則不能令本無吉相之物轉吉,吉之他生理同樣不成。

在術語形式上,本卷以「生」與「能生」並舉,點出他生論者所立之二相——所生與能生——本身即構成過失(「亦二相過故」),這是本部用以拆解他生結構的特殊術語。

綜觀此段,《百論》論「他生」之獨特處在於:並非單獨成立他生之議題,而是將他生與自生、共生並列為「凡生法三種」,以「求不可得」之觀察方式總破三種生起;其中他生之破,尤其依「自相無故他相亦無」之相依性論證,與「無窮過」之歸謬而立。
