What This Concept Is Saying
A first approximation, and why it isn't enough
The term 假有法 — literally "phenomena of provisional existence" or "designated existents" (*prajñapti-sat*, sometimes rendered "conventionally real phenomena") — names one of the most precise and most easily squandered ideas in Buddhist philosophy. A first pass says: *things exist by being designated by name and concept, and the underlying basis on which such designation rests is the dependent nature (依他起自性, *paratantra-svabhāva*)*. That is the correct skeleton. But the concept earns its weight only when we see why the Yogācāra-Mādhyamaka tradition of Tsongkhapa's lineage insists on this particular phrasing, and what it rules out on both sides.
The classical articulation in the 《入中論善顯密意疏》(a commentary on Candrakīrti's *Madhyamakāvatāra*) is structured as a single tight sentence, easily missed: 依他起自性乃假有法所依因 — "the dependent nature is the support-cause of the designated-existant." This is the most identifiable formulation of the term, and it must be read in both directions at once.
- *Forward*: it tells us that 假有法 is not a free-floating mental fabrication. It is not "anything I call into being." Designated existents are designated *about something* — about a dependent nature that arises from conditions. There is a referent. - *Backward*: it tells us that the dependent nature is not itself a 假有法. It is the basis upon which such existents are designated, not another one of them. They are not the same ontological layer.
This two-sided reading is what prevents the term from collapsing into either idealism or nihilism.
The three-way distinction that makes the term work
To see what 假有法 actually is, the commentary forces us to hold three referents side by side. These are not interchangeable categories; they mark three distinct ontological positions, and the term 假有法 lives in the middle.
1. 假有法 itself — phenomena that exist in the conventional order of names and concepts (名言) but lack inherent, self-natured existence (自性). Cups, tables, persons, mornings, disagreements, debts — they are "there," they function, they are not nothing. But their "thereness" is the thereness of designation, resting on the dependent nature.
2. 石女兒 (the stone-daughter) — a child born of a barren stone woman, the philosophical exemplar of something that fails to exist even at the conventional level. We cannot say "I saw the stone-daughter at the market," because the term has no referent. The commentary uses this as the contrast case: a designation without any underlying support-cause.
3. 離言自性 (the non-conceptual self-nature) / 聖智所行 (the sphere of sage-cognition) — what is reached only when conceptual elaboration falls away and is known directly by the wisdom of a buddha. This is the level of 圓成實性, the perfected nature. It is the opposite mistake: things claimed to be utterly beyond all conceptual designation.
The commentary's central argumentative move, repeated in three places, is: if you mistakenly grant self-nature (自性) to dependent-arising itself, then by parity of reasoning you cannot refuse it to the stone-daughter — and, carried further, you cannot refuse to say that even the stone-daughter is beyond all conceptual elaboration, the sphere of sage-cognition alone. *That* is the absurdum. The conclusion drawn is not that we then affirm the stone-daughter, but that the *premise* (that 依他起事 has self-nature) is what must be rejected. Then the third referent — sage-cognition's direct sphere — can be re-established on its proper ground, without being inflated by mistaking conventional designations for self-nature.
Two ways of "not existing": the most subtle move
The commentary makes one more distinction that is essential and easy to miss: between 真實無 ("empty of true existence") and 名言中亦非有 ("not even conventionally existent"). These look similar; they aren't.
- A stone-daughter is 名言中亦非有. It doesn't exist even conventionally; the word has no purchase. - All the phenomena we encounter are 真實無. They have no true, intrinsic, self-natured existence. But — and this is the whole point — they are not for that reason 名言中亦非有. They remain conventionally existent (假有).
If a Mādhyamika were to be persuaded that, since phenomena lack true existence, they must also lack conventional existence (i.e., they should be like the stone-daughter), then — the commentary notes — the opponent would have to say "therefore they must have self-nature after all" (故彼定應自性有). This is the reductio: collapsing the two senses of "non-existence" forces one, by the opponent's own logic, back to the very self-nature they were trying to deny.
This is why 假有法 cannot be paraphrased as "mere illusion" or "merely mental." It is the precise category that holds open the space between two false friends: the denial of all existence (which makes everything a stone-daughter) and the affirmation of self-nature (which makes the stone-daughter a sage-object).
Where 依他起自性 sits in this picture
The commentary describes 依他起自性 itself in two registers, and both must be held together:
- *Affirmatively*: it is 實有 ("real" — in a technical sense), 非戲論境 ("not the sphere of conceptual elaboration"). It is described as 無外所取而生起 — "arises without an externally grasped object" — meaning it is not constituted by grasping some object on the outside. - *Negatively*: it is 不從自他生 ("does not arise from itself or from another") and has no 自證 ("self-cognition that can know it").
This pair of descriptions is what licenses the term 假有法. If 依他起自性 were just another conventional designation, the term would be circular. If it were a self-natured thing, the term would be reifying. By placing 依他起自性 at the level of dependent arising *without* self-nature, the tradition gives itself a non-conceptual but not-self-natured support-cause, and on that basis the conventional order of designated existents can be honestly said to function.
Life's Walk-through
It is tempting to hear "designated existents" as a metaphysical thesis about how language works. It is also tempting to map it instantly onto physics, neuroscience, or AI, where similar-sounding moves are made. Both moves miss what the tradition is doing. The category is meant to be walked through experience — not thought about from outside. Let me take several scenes and walk them through the schema strictly.
Scene 1 — Commuting, a coffee in hand. I look at the cup. *Cups exist* — the term points to something, I can drink from it, the barista handed it to me. So far I am in the register of 假有法. *Now*, if someone asks what the cup "really is," I can list conditions: the ceramic, the firing, the barista's intention, my request, the café, the language I speak, the way my hand grasps it. None of those conditions is "the cup itself." The cup is not a self-natured thing. It is what gets designated across all of these conditions. It is not, however, a stone-daughter — I cannot say "the cup is like the stone-daughter; it has no existence at all," because it does exist, conventionally. If I do say that, the reductio applies: my disbelief is more self-natured than the cup.
A common mis-map: people collapse 假有法 into "the cup is just a construction of my mind." That is closer to 遍計所執 (the imagined nature) — *imputed* nature wrongly granted self-existence. 假有法 is more modest: the cup exists as designated, not as imagined, and not as self-natured.
Scene 2 — A conflict with a partner. "She always does this," I say. The "she" I refer to is a 假有法 — designated across a thousand memories, gestures, words she has spoken. *Now*, the moment I say "always," I have quietly inflated the designation into a self-natured essence. *She is* "someone who always does this." The stone-daughter counter-example is useful here: my generalization has no self-nature; the "always" is a designation I am imposing, not a thing I am finding. But I also can't swing to the opposite: "she doesn't really exist; the whole pattern is my projection." She exists conventionally; the conflict exists conventionally; my pain exists conventionally. 假有法 rules out both the rigid self-natured "she is always like this" and the dissolving "none of this is real."
Scene 3 — A phone-screen, scrolling through apps. The notifications, the news, the person you are texting — all are 假有法. They exist as designated: through servers, signals, contracts of meaning between people who have never met. *Now*: the moment I am angry at a stranger online, I have concretized the designation — *that* person is a bad person, self-naturedly, in their essence. That is to grant self-nature to a 假有法, which is exactly the move the commentary is criticizing. And yet the message they sent is not nothing; it really did arrive; it really did land in my chest. I cannot dissolve it either. The screen's lessons sit precisely on this edge.
A mis-map to flag here: "this is just dopamine / just neurons / just an algorithm" can sound like 假有法, but it usually isn't. Neuroscience and computational models describe *mechanisms within* the conventional order. They are themselves 假有法. They do not deliver the stone-daughter-status verdict about anything. Mixing levels here is the most common contemporary confusion.
Scene 4 — The sense of "I." I am planning my day. The "I" planning is a 假有法 — designated across body, history, conditions, this moment. *Now*: the moment I assume the "I" is a permanent self-natured thing that *owns* my past and *controls* my future, I have added self-nature to a designated existant. *However*: when I try to dissolve the "I" altogether ("there is no one planning"), I have again collapsed 假有法 into stone-daughter-status, and the reductio bites — my denial presupposes a more rigid "I" than the original mistake.
The middle path the tradition asks for is not "I am illusory" but: the planner is a designation resting on the dependent nature, functioning perfectly well in the conventional order, and not to be reified into a self-natured self.
Scene 5 — Grief. When someone has died, the natural reactions are polarized. Either the person has "really gone" — a kind of self-natured severance, as if their existence were a self-contained substance that has now vanished — or, with a different spiritual vocabulary, they were "never really real" — and here, precisely, the 假有法 distinction matters. The person *was* a 假有法: their presence existed as designated, depended on countless conditions, did not have self-nature. This means: there is no self-natured "they" that has been permanently destroyed. But it does *not* mean: there never was anyone. They functioned; they appeared; the conventional truth of their existence is not undermined by the analysis. Grief, properly understood, is not attachment to a self-natured thing. It is the felt recognition of a designated existant whose support-cause has shifted.
Why Contemporary People Need This
There is a particular pressure on contemporary thinking that makes this category useful in a way it wasn't necessarily for its original audiences.
1. The trap of binary ontological moods. Modern secular culture often flips between two extremes that the term 假有法 is built precisely to disable. On one side is naïve realism — *things are self-natured objects*, including persons, including selves. On the other side is corrosive relativism or "deconstruction" — *nothing is really real; everything is a construct*. The Mādhyamaka analysis is that both are wrong, and the place they go wrong is precisely the same place: confusing designated existence with self-natured existence, then swinging between affirming one and denying the other. 假有法 names the missing third option that doesn't get articulated well in either scientific materialism or in much postmodern critique.
2. The proliferation of designable things. We live among more designations than any prior era — accounts, profiles, scores, ratings, legal persons, corporations, currencies, contracts, reputations, brands. Each of these is, in a clear sense, a 假有法: it has no self-natured existence; it exists because of the support-cause of designations, conventions, agreements, infrastructures. Yet each of these is also *not nothing* — defaults on a loan, a wrongly charged fee, a deleted account, a defamatory review, all have very real effects. Learning to think in the 假有法 register is the missing skill for participating responsibly in this kind of reality. Without it, you either naïvely treat your credit score as self-natured fact, or you cynically say "it's all made up" while your life is shaped by it.
3. The mismatch between AI metaphors and Buddhist categories. AI and brain science make much of "it's just computation," "it's just pattern." These descriptions can *sound* like 假有法, but they are descriptions of mechanisms within the conventional order — they describe one 假有法 (neural firing, software) in terms of another 假有法 (information, computation). They are themselves designations resting on dependent nature. They do not establish the *stone-daughter*-status verdict that the Buddhist analysis is reaching for. This is worth saying carefully: the Buddhist category is not reducible to physicalist or computationalist claims, nor are those claims equivalent to it. The mapping is illustrative, not demonstrative. Anyone claiming "neuroscience proves Madhyamaka" is making a category mistake — at minimum, conflating *mechanism* with *ontology*.
4. The practice of ethical action under emptiness. A common worry: if things are designated existents, why act ethically? The Mādhyamaka response, embedded in the very structure of 假有法, is that this worry itself proceeds from the two horns the analysis dismantles. If ethical action were grounded in self-natured selves, then yes, on analysis those would be empty. But ethical action is itself a designated existant, resting on dependent nature — and the reductio applies to its denial just as much as to its affirmation. The Mādhyamika practitioner does not have a *more* or *less* committed engagement with conventional reality than anyone else; they have an engagement that has been held to its actual ontological status and survived the analysis.
Common Misreadings and Clarifications
Misreading 1: 假有法 = "doesn't really exist." This is the most common collapse. *In a colloquial frame*: "It only exists conventionally, so it's basically not real." The analysis in the commentary is precisely against this. "True emptiness" (真實無) is the negation of self-nature; it is *not* the affirmation of stone-daughter-status. The whole force of the stone-daughter counter-example is to distinguish the two. Things genuinely exist as designated existents. The cup is not the stone-daughter.
Misreading 2: 假有法 = "only a mental construct" / idealism. This maps 假有法 onto the imagined nature (遍計所執), the layer where designations have been wrongly granted self-existence. 假有法 is the layer *beneath* that mistake. It is the functioning order of designated existents *before* the mistake has been made. To call it "mental" is to import a dualism of mind and world that the tradition does not endorse in this form. Designations here include any conventional term, including "this," "now," "the room's temperature" — not just mental imagery.
Misreading 3: 依他起自性 = 假有法.* This collapses two distinct levels. The commentary insists on the formula 假有法所依因: the dependent nature is *the support-cause of* 假有法, not another 假有法. The distinction is doing real work — without it, the analysis has no anchor and dissolves into a bare assertion that everything is merely designated.
Misreading 4: 假有法 implies that there is no functional difference between stone-daughter and real phenomena.* The opposite is the point. There is a vast difference, and it is captured by the difference between 名言中亦非有 and 真實無. The stone-daughter fails at the conventional level; real phenomena function there with full force. The reductio in the commentary exists specifically to prevent this flattening.
Misreading 5: 假有法 is just a Mahāyāna idea; the early suttas don't have it.* The framework of three natures is articulated in Yogācāra-Mādhyamaka literature, but the underlying distinction — that things function without having self-nature — is everywhere in the early suttas. The much-quoted line from the 《心經》(Heart Sutra), "照見五蕴皆空" ("the five aggregates seen to be empty"), is operating in the same conceptual neighborhood: phenomena are 空 (empty of self-nature) without thereby being unreal or unusable. The terminology of 假有法 is one precise way of *holding* that insight in the face of two opposite temptations.
Misreading 6: "Modern physics / AI / neuroscience proves 假有法." This is the category mistake mentioned earlier. Modern frameworks can *model* dependent arising, designated existence, even something like relational ontology. They can offer analogies. They cannot deliver the Mādhyamaka analysis because their vocabularies do not include the distinction between 實有 / 非戲論境 and 石女兒-status, and they do not perform the reductio that the commentary performs. To claim proof is to claim too much; to claim analogy is fair. The Mādhyamaka claim is itself made within a different discipline — analysis of designations and what they can sustain — and must be evaluated on its own terms.
If one sits with this for a while, 假有法 turns out to be one of the most honest things philosophy has ever said about experience: yes, there are things; no, they are not self-natured; yes, they function; no, the analysis that reveals their emptiness does not abolish them. The category is the holding-place for that *yes-and-no* that, in everyday life, we keep failing to keep both halves of — and that failure is the source of much unnecessary suffering, both on the side of rigidity and on the side of nihilism. The tradition's wager is that if you can stay with the analysis, the world does not collapse; it shows up more clearly, without the spurious self-nature we keep trying to foist on it.
