What This Concept Is About

A Deeper Matter Than "Certainty"

When modern readers encounter the two Chinese characters 決定, their first reaction is usually "certainty," "making up one's mind," or "calling the shots"—but this is precisely the most common misreading. In the *Mūlamadhyamakakārikā* (《中論》, attributed to Nāgārjuna), 決定 is a highly precise philosophical term. It refers to: the intrinsic nature (svabhāva) by which a thing is "originally thus," does not depend on anything else for its arising, and cannot itself be altered.

The commentary by Qingmu (青目) gives a clear definition:

「決定者,名本實有,不因去法生;不決定名本實無,以因去法得名去者。」

*"Decisive existence" means something is originally and truly existent, not arising in dependence on another existent; "non-decisive existence" means something is originally non-existent and is only designated as existent in dependence on another existent.*

In plainer terms: "Decisive" means something that is originally and truly present, that can stand without relying on other conditions, and that does not change; "non-decisive" means something that has no self-nature to begin with and is only provisionally established through dependent relation with causes and conditions.

The treatise itself states it even more directly: "性名決定有,不可變異" — "the term 'nature' means decisively existent and immutable." Here, "nature" (性, svabhāva, "self-nature") and "decisive existence" are the same thing. So translating 決定 into modern Chinese, the closest equivalents would be: "an essential, intrinsic reality," or more clumsily but more accurately—"the unchanging essence behind a thing."

Why Does Nāgārjuna Refute It?

The core concern of Madhyamaka is "the true nature of all dharmas" (諸法實相)—what do things actually are? In ordinary everyday experience, people tend to feel that behind each thing there is an "original self": this table is originally a table, this person is originally this person, this "I" originally has some fixed character, some essence.

Nāgārjuna's point is: this feeling of "originally thus" is itself the deepest layer of attachment. It is not a lighthearted idea but the underlying operating system of the entire cycle of saṃsāra—how you view things, how you cling to self, how you understand causality—all of it grows from here.

Two Metaphors That Preserve the Structure of the Original

The Qingmu commentary employs a matched pair of metaphors to illustrate what 決定 means. These two metaphors are not mere ornament; they are strictly used to clarify the rule that "decisive = immutability":

- True gold cannot be changed: True gold cannot be destroyed by fire, cannot be worn away by grinding. No matter what processing it undergoes, it remains what it is. This is the ideal state of "decisive existence"—a thing's inner essence remains constant and unchanging regardless of how external conditions shift. - The nature of darkness does not become light; the nature of light does not become darkness: The essence of darkness cannot become brightness, and the essence of brightness cannot become darkness. If "darkness could become light," then the darkness in question would not be "true" darkness but something mixed with something else—that would not be a "decisive" darkness.

Stack these two metaphors together: "decisive existence" means: a thing must be thoroughly its own, itself by itself, containing nothing else, and admitting no change whatsoever.

Conversely, everything in reality—tables decay, people change, emotions rise and fall, relationships arise and cease—these phenomena themselves demonstrate: nothing is "decisive." This is not a conclusion requiring complex logic but a fact visible with open eyes.

Four Theoretical Faults of "Decisive Existence"

The *Mūlamadhyamakakārikā* points out from four directions the catastrophic consequences of clinging to "decisive existence":

First, the dilemma of mutual dependence. The chapter on the mover (去品) says: the mover, the act of moving, and the place moved to—these three "all depend on one another"—because there is the act of moving, there is the mover; because there is the mover, there is the act of moving; because there are these two, there is a place moved to. The chapter on the burner and the burning (燃可燃品) goes a step further: "If a dharma is established through dependence, then that dharma in turn becomes the condition of its own condition. Thus, if there were decisive existence, there would be no two things." If burning can only be established through a combustible, and the combustible's establishment in turn requires burning, then each serves as the other's condition—neither can be the "decisive" ground of the other. Decisive existence has no place to stand.

Second, the dilemma of reduction to absurdity. The chapter on the mover says: "決定有去者,不能用三去;不決定去者,亦不用三去" — "If the mover were decisively existent, he could not use any of the three kinds of moving; if the mover were non-decisive, he likewise could not use any of the three kinds of moving." If the mover were decisively and truly existent, he should be able to move without depending on the act of moving—in which case he would be moving eternally, with no moment of stopping. If the mover were entirely non-decisive, he would not exist at all, and there would be no question of where he goes. Both sides fail.

Third, the necessary fall into eternalism or annihilationism. "If a dharma has fixed nature… if it is not non-existent, then it is eternal; what was first existent and is now non-existent—that is annihilation." If a thing has a fixed "essence," then either it exists forever (the eternalist extreme), or something that was "originally thus" later disappears—which is utter annihilation (the nihilist extreme). Neither conclusion matches reality.

Fourth, the rejection of causes and conditions. "If you see dharmas as having decisive nature, then you see dharmas as having no cause and no condition." Once you hold that something has an "originally thus" self-nature, that means its existence requires no conditions whatsoever—this directly demolishes the entire edifice of dependent origination (pratītyasamutpāda). Yet the world is manifestly produced through the concurrence of causes and conditions. An irreconcilable contradiction results.

Finally, the *Mūlamadhyamakakārikā* gives a summarizing verse: "若有決定性,世間種種相,則不生不滅,常住而不壞" — "If there were decisive nature, then the various appearances of the world would neither arise nor cease, but would be permanent and indestructible." If there truly were a "decisive essence," then all phenomena in the world should not arise, should not cease, and should remain there unmoving forever. Yet we plainly see flowers bloom and fall, people gather and part—this itself is the most direct perceptual refutation of "decisive existence."

The Place of "Decisive Existence" in the Entire Path of Liberation

"Decisive existence" is one of the core objects of refutation in Madhyamaka, but it is not an isolated target. It is the most subtle form of the entire "ignorance" (無明, avidyā):

- It is deeper than "clinging to a specific thing"—not clinging to "this table," but clinging to "there being a 'tableness' behind the table." - It is more fundamental than "eternalism" (常見)—eternalism only says "things do not change"; "decisive existence" says "things originally have an unchanging inner essence." - It is the substratum of "self-grasping" (我執, ātmagraha)—the reason "I" appears so real, so unshakable, is precisely because the deepest assumption "there is decisively a self" props it up from beneath.

Thus, refuting "decisive existence" is not a technical exercise in philosophical argumentation but a direct thrust at the deepest point of the saṃsāric view—overturning the underlying assumption that "everything has an original face." Once this layer is overturned, the entire structure of concepts like "self," "dharmas," "causality," and "practice" must be re-understood.


A Walkthrough in Everyday Life

The abstract concept is done. Now let us take this set of ideas into the daily life of contemporary people and see how it "walks."

Scenario One: "I'm Just This Kind of Person"

Situation: A friend urges you to switch to a more suitable career. A thought surfaces in your mind: "But I'm just this kind of person. I'm not suited for that kind of thing."

**Running it through the *Mūlamadhyamakakārikā***:

"I'm this kind of person"—hidden here is an assumption of "decisive existence": I have a fixed "essence" (personality, temperament, endowment), and this essence was there from the beginning and will not change.

How would Nāgārjuna look at this?

- From "mutual dependence": Your current "personality" is the product of the convergence of past causes and conditions—family, education, several relationships, failures, successes. It did not pop out of thin air as a "self-nature." - From the "dilemma": If you were "decisively" this kind of person, you should never do anything inconsistent with the traits of "this kind of person"—but in fact, on some late night, at some turning point, you may have done something utterly unlike "you." This shows that "decisively having a self" does not actually hold. - From "direct perception": The person you were ten years ago and the person you are now already differ in personality, preference, and ability. If "you" were "decisive," these changes should not have occurred.

The most likely point of misprojection here: When many people hear "no decisive nature," their first reaction is panic—"Then I am nothing? Am I still me?" This is understanding "non-decisive" as "completely nonexistent." But Madhyamaka refutes "decisive existence"—it does not say there is no continuity whatsoever, no identifiable traits. On the level of conventional truth (saṃvṛti-satya), you still have your habits, your tendencies, your temperament—only these are not "the real, unchanging essence behind it all." They are results of dependent origination, and they can be recognized, adjusted, and loosened.

Scenario Two: "This Relationship Was Supposed to Be Like This"

Situation: You argue with your partner, and you are inwardly convinced: "This is just our pattern. He/she is just this kind of person. This is the essence of it. It cannot be changed."

**Running it through the *Mūlamadhyamakakārikā***:

"The essence of our relationship"—this is freezing a dynamic relationship, constantly shifting within causes and conditions, into a "decisive" existence.

- From "mutual dependence": This relationship is what it is now because of the respective states of two people, the external environment, past traumas, present pressures—the convergence of these conditions. No single part of it is "originally supposed to be this way." - From the "dilemma of the burner and the burning": You and the other person actually condition each other—you treat him/her that way because he/she first treated you that way; he/she treats you that way because you first did such-and-such… In this loop of mutual shaping, no "decisive" origin point can be found. - From "true gold cannot be changed": If your relationship were "decisively" some pattern, it should always be that way—but you may have had an extremely sweet period before, and now you are draining each other. This shows the relationship changes; it has no "decisive" essence.

The most likely point of misprojection here: Refuting "decisive existence" does not mean "everything is an illusion; nothing need be taken seriously." Relationships have their inertia, their structure, their observable patterns—these are all real things on the level of conventional truth. What Madhyamaka refutes is that "essence behind it all," allowing you to see that relationships are in fact transformable, not locked in place by some "fated essence."

Scenario Three: "This Job / This Achievement Defines Me"

Situation: You lose your job, a project fails, or your career hits a plateau. A voice deep inside says: "I failed. I am 'just' the kind of person who fails."

**Running it through the *Mūlamadhyamakakārikā***:

"My worth is determined by this achievement"—behind this lies the assumption "I have a decisive essence of worth": value is not the convergence of causes and conditions but some inner, fixed "how much I am worth."

- From the "eternalism and annihilationism" angle: If your worth were "decisively" determined by some achievement, then either that achievement lasts forever (impossible), or your worth was "originally present and now absent"—that would be annihilation. But in fact, along other dimensions, you still have value, ability, and dignity. - From "rejection of causes and conditions": The sense of worth arises from causes and conditions—it requires concrete actions, concrete feedback, concrete relationships to support it. Freezing worth into "my essence" amounts to denying all these conditions. And in fact, when the conditions change, the sense of worth changes with them.

The most likely point of misprojection here: "Non-decisive" is not "nothing has meaning." Meaning can still exist—only it is not something radiated from "your inner essence"; it emerges within dependent origination—and therefore, when the conditions change, meaning can re-emerge.

Scenario Four: Scrolling Your Phone—"I Just Love Watching This"

Situation: You have scrolled through short videos for three hours. You put down the phone, feeling a bit guilty, and think: "I'm just weak-willed. I just love watching these."

**Running it through the *Mūlamadhyamakakārikā***:

- From the "dilemma": If you were "decisively" someone who loves watching short videos, this tendency should never change—but there may be moments (for instance, when you are deeply absorbed in something engaging) when you have no desire to watch short videos at all. This shows that "decisively loving short videos" does not hold. - From "true gold cannot be changed": What can change has no "decisive" essence. You love watching today; tomorrow you may not. You love watching this app; switch to another and you may not. There is no "self with the self-nature of loving to scroll"—only various causes and conditions (fatigue, boredom, an ingeniously designed algorithm) pushing you toward this behavior.

The most likely point of misprojection here: Acknowledging "non-decisive" is in fact the beginning of liberation. If "I am decisively this kind of person," then change would be a violation of essence—that is despair. But seeing "there is no decisive person, only various causes and conditions" means change is possible—because conditions can be adjusted.

Scenario Five: Facing Loss—"This Was Supposed to Be Mine"

Situation: A relationship ends, an opportunity is missed, a loved one passes away. Inside you, something churns: "I should not have lost this. This was supposed to belong to me."

**Running it through the *Mūlamadhyamakakārikā***:

- From "decisive existence excludes causes and conditions": If something were "decisively" supposed to be yours, it should not leave. But it has left—this itself shows there is no such thing as "decisively supposed to be yours." - From "direct perceptual refutation": All things are changing. Nothing is "originally supposed" to remain there forever. The assumption of "originally supposed to" is something the mind adds on its own; it is not a property of the thing itself.

The most likely point of misprojection here: Madhyamaka is not cold-blooded—it is not saying "you should not cling to anything." Rather, it is saying: suffering does not arise from the loss itself, but from the fact that on top of the loss you add "this should not have happened," "this should not have changed"—behind this "should not" lies the assumption of "decisive existence." Seeing this assumption, seeing that it is not a property inherent in things, is what loosens the stickiness of suffering.


Why Contemporary People Need It

Treating the Contemporary Disease of Essentialism

Contemporary culture—whether on the left, the right, in psychology circles, or in popular culture—shares one deep assumption: behind every person, every group, every phenomenon, there is a fixed "essence."

- Personality tests (MBTI, the Enneagram) tell you "you are an INFJ," as if this were your "decisive essence." - Identity politics emphasizes "I am a member of group X; this identity determines everything I experience," essentializing complex social situations into a single identity. - Self-help culture encourages you to "find your true self," as if that "true self" were a fixed treasure buried underneath, waiting for you to dig it up.

Madhyamaka's "refutation of decisive existence" directly challenges this entire narrative: there is no "true self" waiting out there for you to find; there is only the present moment of converging causes and conditions, emerging, flowing, and changing at every instant. This is not nihilism—it is loosening "I" from a pinned-down specimen into a living process.

Why This Matters for Mental Health

More and more people in psychotherapy recognize: rigid core beliefs are the root of much suffering. A person deeply convinced that "I am unlovable" will interpret every ripple in every relationship as "see, I really don't deserve it." The structure of this belief is precisely "decisive existence"—"I" have a fixed inner essence of "worthy/unworthy."

The Madhyamaka insight can be connected here: "I" have no "decisive" essence of value; my value emerges within causes and conditions and can change as conditions change. This is not self-comfort but a structural loosening of the concept of "self"—you are not the thing locked in place by an essence; you are a process that can be reshaped by conditions.

Treating the Fear of the Irreversible

At the bottom of much contemporary anxiety is: "This is already decided. It's too late."—Losing a job means it is over forever; divorce means intimate relationship can never happen again; not accomplishing something by a certain age means the opportunity is gone forever. Here, "decided" is in fact clinging to "decisive existence"—taking the conditioned result of a particular moment as an unchangeable "essence."

Madhyamaka says: no present moment is "decisive," because everything is the convergence of causes and conditions, and conditions can change—this is not the cheap chicken-soup consolation of "everything will be fine," but a re-seeing of the actual way things exist.

A Parallel with Contemporary Science (Analogy, Not Equivalence)

Many fields of modern science have, in different directions, run into this wall of "decisive existence":

- Complex systems theory points out that minuscule differences in initial conditions lead to dramatically different outcomes (the "butterfly effect"), meaning that any "decisive prediction" is infeasible in complex systems. - Neuroscience has found that the brain's plasticity far exceeds traditional imagination—neural connections are being reorganized throughout life; a "person" is not "decided" by some neural structure. - Evolutionary biology reveals that traits are not determined by some "essential gene" but are the result of multi-layered causal interaction among genes, epigenetics, environment, and culture.

But it must be clearly stated: these scientific findings do not amount to proving Madhyamaka philosophy. "Decisive existence" in Madhyamaka is a metaphysical-level clinging; science deals with regularities at the phenomenal level—the two are at different levels, speak different languages, and have different aims. But as points of comparison for contemporary experience, they do allow us to feel more directly that clinging to "decisive existence" is not only a philosophical error but also out of step with contemporary people's latest understanding of themselves and of the world.


Common Misreadings and Clarifications

Misreading One: "Decisive" Means "Certain" or "Making Up One's Mind"

This is the most superficial confusion. "Decisive existence" in Madhyamaka is a metaphysical concept referring to "an originally real, unchanging self-nature"—not the everyday sense of "making a decision" or "certainty." What Nāgārjuna refutes is the deeper "essence" behind things; he is not saying people cannot make ordinary daily choices.

Misreading Two: "Refuting Decisive Existence" Means "Everything Is Nothingness"

This is the classic annihilationist view. Refuting "decisive existence" means there is no unchanging essence—not that nothing exists at all. On the level of conventional truth, things still have their characteristics, their functions, their arising and ceasing—only these are not "decisive." The *Mūlamadhyamakakārikā* itself never denies dependent origination; on the contrary, it refutes "decisive existence" precisely in order to rescue dependent origination—because once "decisive existence" is admitted, the entire edifice of causality and dependent origination collapses.

Misreading Three: "Decisive Existence" Equals "Fatalism"

Fatalism says "everything is destined"—this is itself a typical form of "decisive existence": the view that the future has already been determined by some fixed power. Madhyamaka's refutation of "decisive existence" is precisely the refutation of this mode of thinking. Having no "decisive" means nothing is "destined," every moment of dependent origination has its real causal functioning, but no single point is an "immutable essence."

Misreading Four: "Non-Decisive" Means "Nothing Need Be Taken Seriously"

Some people hear "all things are without decisive nature" and think they can drift with the current and indulge themselves. This is degrading a profound philosophical insight into a lazy excuse. Madhyamaka has never said "dependent origination = no responsibility." Quite the opposite—seeing that everything is dependently originated means every one of your actions is real causality, not something pushed along by a "essential you." This actually makes "choice" and "responsibility" more concrete.

Misreading Five: "No Decisive Nature" Means There Is No "Self" That Can Practice

Some worry: if "I" is not decisive, then who is practicing? This is understanding "non-decisive" as "utterly without any continuity." Madhyamaka's "non-decisive" refutes that "unchanging essential self"; it does not say there is no conventional self composed of the five aggregates (五蘊, pañcaskandha), continuing in transformation, capable of practice. Nāgārjuna never denies the conventional "self"—what he refutes is the clinging that takes this conventional self as having real self-nature.

The Final, Finest Misreading: "Decisive Existence" and "Emptiness" Are Two Opposing Sides

Many people imagine Madhyamaka as a choice between "emptiness vs. existence." In fact, "decisive existence" is the object of refutation, and "emptiness" (空, śūnyatā) is the truth seen after the refutation—but "emptiness" is not another "decisive" essence, not saying "everything has an essence called emptiness." Emptiness is the horizon opened by the very negation of "decisive existence"—neither "there is a fixed essence" nor "there is nothing at all," but rather things as they are in this very moment, dependently originated, illusion-like and transformation-like.


Refuting "decisive existence" does not ask you to become a nihilist who believes nothing and clings to nothing. It invites you to see: those "essences" you thought unbreakable—"my personality," "my worth," "my fate," "the essence of my relationships"—were never "decisive" at all. They have always been alive, flowing, dependently originated.

This seeing is not knowledge. It is loosening. And after loosening, the way you live will be different.

Canonical EntryAI-generated

一、定义与核心要义

「决定」于《中论》中指本来实有、不因他法而生、不可变异的自性执持,为中观学破斥的核心对象之一。其本质含义与「性」(svabhāva)相通,指诸法具有固定不变的实在性。本经以「决定」与「不决定」对举:决定者本实有,不待因缘;不决定者本实无,依因待而假立。

二、主要阐述

《中论》从多重角度破斥「决定」之执:

其一,因待互成之论证。去品指出,去法、去者、所去处三法皆相因待,因去法有去者,因去者有去法,因是二法有可去处,故「不得言定有、不得言定无」,三法虚妄,空无所有,唯是假名如幻。燃可燃品进一步揭示逻辑困境:若燃因可燃而成,可燃还因燃而成,二者互为前提,「如是决定则无二事」,「无定故,不可得」。

其二,与运动之关系。去品偈颂:「决定有去者,不能用三去;不决定去者,亦不用三去」。青目释展开:若去者决定有,则应离去法而自有去者,不应有住;若不决定,本无去者,亦不能用三去。两难之下,去者与去法皆无实可得。

其三,与作者、业之关系。作者作业品云:「决定有作者,不作决定业;决定无作者,不作无定业」;「决定业无作,是业无作者;定作者无作,作者亦无业」。决定之作者与决定之业不能互相成立,定与不定之间亦无真实作用关系。

其四,与常断、因果之关系。执「决定有性」的理论后果:若法有定性,则「非无则是常;先有而今无,是则为断灭」,必落常、断二边。又「若汝见诸法,决定有性者,即为见诸法,无因亦无缘」,决定有性即排斥因缘生义。最终,「若有决定性,世间种种相,则不生不灭,常住而不坏」,与现见生灭变异的世间相直接矛盾。

其五,以喻显义。青目释以「真金不可变」及「暗性不变为明、明性不变为暗」为喻,说明「决定有」即「不可变异」,反证:诸法既有变异,即无决定之性。

三、不同部类与译本的表述差异

本概念之论述仅见于《中论》(中观部·《中論》),本任务未提供其他部类之资料,故此节仅列本经内部用词之歧出:

本经使用多种表述方式指涉同一概念:作「决定」(「决定有去者」)、「定有」「定无」(「不得言定有、不得言定无」)、「决定有性」(「若诸法决定有性」)、「决定性」(「若有决定性」)、「定性」(「若法有定性」)。其中「决定」与「性」(svabhāva)直接等同,青目释明言:「性名决定有,不可变异」。

此外,「决定」与「不决定」对举使用:决定指本实有、不因他法生;不决定指本实无、因去法得名。

四、与相关概念的关系

「决定」与「性」(svabhāva)在本经中直接等同,二者皆指不可变异的自性实有。「决定」与「常」相关——执决定性则必堕常住之边。「决定」与「因缘」相违——执决定有性即排斥因缘生义。此外,「决定」与「作者」、「业」、「去者」、「去法」、「燃」、「可燃」等概念皆构成破斥对象,揭示其彼此间因待互成而无实自性。

五、代表性原文引用

- 「决定者,名本实有,不因去法生;不决定名本实无,以因去法得名去者。」 - 「决定有去者,不能用三去;不决定去者,亦不用三去。」 - 「决定有作者,不作决定业;决定无作者,不作无定业。」 - 「决定业无作,是业无作者;定作者无作,作者亦无业。」 - 「若法因待成,是法还成本因待。如是决定则无二事。」 - 「性名决定有,不可变异。」 - 「若诸法决定有性。」 - 「若法有定性,……非无则是常;先有而今无,是则为断灭。」 - 「若汝见诸法,决定有性者,即为见诸法,无因亦无缘。」 - 「若有决定性,世间种种相,则不生不灭,常住而不坏。」

大智度論T1509 · 釋經論部

本部《大智度論》論述「決定」概念,主要以「畢定」一詞為核心展開,並輔以「決定智」之界定。

一、「決定智」之界定。載:「行者捨諸法,亦不依止慧,亦無所分別,是為決定智!」此以「捨諸法」、「不依止慧」、「無所分別」三層義涵界定「決定智」——行者捨離一切法相、不依著智慧之相、亦不起分別,即名決定智。此處之「決定」側重離相無分別之智的特質。

二、「畢定」之核心涵義與專指佛道。中須菩提與佛反覆問答「菩薩摩訶薩為畢定?為不畢定?」,佛明確回答「菩薩摩訶薩畢定,非不畢定」,並進一步指出「非聲聞、辟支佛道中畢定,是佛道中畢定」——「畢定」乃專就佛道而言,非二乘之決定。

三、三種畢定菩薩皆悉決定。佛言:「初發意菩薩亦畢定,阿鞞跋致菩薩亦畢定,最後身菩薩亦畢定」,三類菩薩皆為畢定。並補充:「菩薩摩訶薩從初發意乃至道場,於其中間,無有善根不具足者……當得阿耨多羅三藐三菩提」,意謂自初發心以至道場之間善根無不具足,故必當成佛。

四、畢定之深義——佛以畢定知照見一切法。釋文中闡明:「佛知雖無量阿僧祇劫積大功德,必退作小乘者;亦知微細蜫虫雖未有善心,過爾所劫發心,後當作佛。定知一切法皆如是,從是因得是果,是故名佛;一切法中無礙,以畢定知故。」此處「畢定」兼攝兩層:其一為究竟決定無疑之智;其二為必定成就之義。是佛之所以為佛的根本特質。

五、畢定菩薩不墮惡道、不生邊地及長壽天。針對畢定菩薩是否墮三惡道之疑,佛以八人乃至阿羅漢不墮惡道為例,論證菩薩從初發心以來布施持戒、斷諸殺生等十不善道,「若是人墮三惡道,無有是處」。並解釋菩薩以慈悲故不著禪味,故不生長壽天;以拔除悋法、不著邊見故,不生邊國惡邪見家。

六、相關術語形式之辨明。本部論中以「阿鞞跋致」表不退義〔chunk:27492-27496〕,「畢定」與「阿鞞跋致」於此部中互訓並用,如「有說『諸菩薩退而不畢定』,有處說『菩薩畢定不退』」、「畢竟空故,諸法皆不退」。另提出「一切種智」之名,指畢定菩薩斷盡煩惱習所當得之究竟智。

中論T1564 · 中觀部

中論對「決定」一詞的論述,主要集中於破斥「決定有」與「決定無」兩端,以顯示諸法的空無自性。其用法如下:

一、「決定」的基本界定 中論青目釋明確指出:「決定者,名本實有,不因去法生」,即「決定」意味著事物原本真實存在、不依他法而自有。此一界定貫穿全論對此概念的運用——「決定」即等同於自性成立、本來實有。

二、以「去」為例破斥決定 觀去品以「去者、去法、所去處」三法為例,設為偈頌:「決定有去者,不能用三去;不決定去者,亦不用三去。去法定不定,去者不用三,是故去去者,所去處皆無」。無論是決定有去者或是不決定去者,皆不能用未去、已去、去時三種去法。釋論進一步說明:若決定有去者,離去法應有去者,不應有住;若去者不決定,則本實無去者,亦無從用三去。層層推究之下,三法皆是因緣和合、相因待而有,「不得言定有、不得言定無」,是故「決定知,三法虛妄,空無所有」。可見「決定」在中論中是徹底被解構的對象,而非可成立的概念。

三、雙遮兩端的破斥結構 同樣的雙遮手法應用於「作者」與「業」的關係:「決定有作者,不作決定業;決定無作者,不作無定業」;「決定業無作,是業無作者;定作者無作,作者亦無業」。無論決定有作者或決定無作者,皆不能成立作業或不作業,由此顯示作者與業皆無自性。

四、決定性與緣起的對立 中論更從緣起立場指出:「若有決定性,世間種種相,則不生不滅,常住而不壞」。若諸法有決定性(固定不變的自性),則世間種種差別相將無法生滅流轉,墮於常住不壞之見。這與緣起法的生滅現象直接相違,故中論以否定「決定性」來肯定緣起的流轉不息。

術語特色 中論論及此概念時,使用「決定」、「不決定」、「決定性」等詞,並無特殊異譯別名。青目釋將「決定」解為「本實有」,是該論對此概念的核心界定——決定即意味著自性成立、本來實有,這正是中論所要破斥的根本執著。

《瑜伽師地論》論「決定」一詞,以「決定」為正稱,並衍出「墮於決定」、「決定地」、「決定行地」、「決定勝解」等用語形式。

一、菩薩階位中之「決定」。本論明列菩薩三種「墮於決定」——安住種性墮決定、發菩提心墮決定、不虛修行墮決定。諸佛如來授墮決定記者,依最後「不虛修行墮決定」位而立。「墮於決定」即菩薩對無上正等菩提之不可退轉的判定。又以十種菩薩攝修學階位,「未墮決定」、「已墮決定」對舉,並標「決定地」、「決定行地」以明其位與行。

二、「攝決擇分」中之「決擇」。本論另設「攝決擇分」一大科,於有尋有伺地、三摩呬多地、非三摩呬多地、有心地、無心地、聲聞地、菩薩地、有餘依地、無餘依地九地之中,各別作「決擇」之文。卷首科判亦以「決擇」與體、所緣、行相、等起、差別、流轉並列,又有「引果生、決擇」之嗢拕南。此處「決擇」與「決定」詞形有別而義近,皆為對所緣義理之確定判定;唯「決擇」側重抉擇辨析之過程,「決定」側重確定不移之果位。

三、修證實踐中之「決定」。論苾芻為離欲貪勤修方便,以淨相作意思惟,於煩惱斷與未斷「方得決定」;由猛利見審觀察得「決定勝解」——謂於應生煩惱之處已能勝伏令不生起。

四、附「決了」之詞。文中有「不可思議、意趣理門應隨決了」之語,與「決定」義近,謂對深妙理趣之確定明了。

綜上,本論以「決定」貫穿階位論、修行論、抉擇體系三方面:階位論中為菩薩證悟之不退轉位;修行論中為離煩惱之智決;抉擇體系中以「決擇」之名總攝九地義理之辨析。所用詞形以「決定」為主,輔以「決擇」、「決了」。
