Preface¶

The subject of this volume is doctrinal classification and judgment.

Doctrinal classification is indigenous to Buddhism. Tiantai classifies teachings from the standpoint of the Lotus Sūtra; Huayan from that of the Avataṃsaka Sūtra. Each uses the doctrine of its authoritative scripture to rank the profusion of teachings and determine which are higher or lower, definitive or interpretable. In the modern period, Venerable Yinshun proposed his classification into "three systems": the system of emptiness of nature and mere designation, Madhyamaka; the system of false imagination and Consciousness-Only, Yogācāra; and the system of true permanence and mind-only, tathāgatagarbha. Taking fundamental Buddhism—the Āgamas and Nikāyas—as his standard, he adopted a reserved position toward the third system. This volume continues precisely that tradition of doctrinal judgment. Its position resembles Yinshun's three-system account, but its angle differs. Yinshun concentrates on historical strata and doctrinal lineages. This volume asks more directly what kind of attachment lies concealed within the philosophical motivation of each system's soteriology.

One difference from traditional doctrinal classification should also be explained. Having ranked the teachings, Tiantai and Huayan still gather all of them under buddhavacana, assigning each a place as expedient or ultimate. This volume does not take that final step of inclusion. Its form of judgment descends from tradition, but its basis is philosophical argument: whether a claim stands depends only on its reasons, not its provenance.

This must be stated in advance: the volume does not pretend to fairness or neutrality. Volume I was history. In organizing the history of Buddhist philosophy, it sought to restrain judgment and present the origins and consequences of each system. Volume II is argument. It begins from the historical facts of Volume I and judges them directly without avoiding a position. The analyses that follow proceed from a specific standpoint rather than offering a balanced presentation that distributes equal criticism among all systems. This is not an academic impropriety. Doctrinal judgment has never been neutral description; it is evaluation from a fundamental position.

Lack of neutrality does not remove the obligation to argue. This volume follows two rules. First present a system's central claims and strongest defense, then criticize them. Wherever possible, use premises acknowledged within the system itself. Yet the limits must be honestly declared: the criticism is not confined to internal critique. Its final standard is the early Buddhist baseline established in the introduction. The reasons for choosing it will be supplied openly, without pretending neutrality. Nor are the instruments of examination limited to resources recognized by each system; references to phenomenology, psychology, and philosophy of science will also be used. Readers can therefore test two things: whether each criticism addresses the best version of its object, and whether the criterion applied at each point is shared by the parties or belongs only to the baseline.

The volume's baseline inclines toward early Buddhism, whose scope must be defined precisely. On the Southern side it takes the four Nikāyas, together with the few texts in the Khuddaka Nikāya generally recognized by scholars as belonging to the earliest stratum. Chief among them are the Aṭṭhakavagga and Pārāyanavagga of the Sutta Nipāta, which can be checked against Chinese parallels such as the Arthapada Sūtra. Early verses in the Itivuttaka, Udāna, and Dhammapada are cited selectively. Most other works of the Khuddaka Nikāya belong to later strata and do not enter the baseline. On the Northern side it uses three of the four Āgamas, excluding the Ekottarika Āgama: the Dīrgha, Madhyama, and Saṃyukta Āgamas. The school affiliation of the Ekottarika Āgama has long been disputed, and it incorporates material that is later and closer to Mahāyāna tendencies. It may serve as collateral evidence but not as part of the baseline.

This baseline is not a body of "original texts" untouched by sectarian color. The Saṃyukta Āgama descends through the Sarvāstivāda transmission, the Dīrgha Āgama through the Dharmaguptaka, and the four Nikāyas were likewise edited within a Vibhajyavāda lineage. The earliest layer that can be cross-checked between Northern and Southern transmissions is selected for being early and verifiable, not for being unedited.

More importantly, the earliest textual stratum gives us what is early, not what is true. Moving from "this is the earliest teaching recoverable through evidence" to "this should serve as the standard of doctrinal judgment" requires philosophical reasons. This volume does not disguise the move as a direct conclusion of philology. There are three reasons. First, the teaching is practical: every doctrine points toward a sequence of practice and does not form an explicit, independent metaphysical system. The word explicit matters because, as this book has consistently read it, the teaching is not without a metaphysical outline. The outline appears precisely at its boundaries—in the questions the Buddha refuses to answer, the undeclared questions, and the concepts he refuses to establish, as Volume I explained. But the outline remains silent and is never stated positively as a doctrinal system. Much of the work of later schools consisted in filling the boundary with positive claims. Second, it lies closest to experience. The reduction of suffering and loosening of greed, hatred, and delusion are changes practitioners can examine within their own present experience. Such examination is not free from conceptual frameworks; every first-person report is shaped by expectation and doctrine, a problem the Yogācāra part will confront directly. Nevertheless, relative to later systems, the teaching posits the fewest unverifiable things. Its weightiest such item is rebirth, which every subsequent system shares. Chapter 2 of the introduction will account for that liability separately. Its central claims remain closest to experience. Third, it concentrates on the cessation of suffering. From beginning to end, the structure of the Four Noble Truths addresses only how suffering arises and how it ceases; it does not take up ontological problems unrelated to suffering's cessation. Using this as its standard, the volume holds that later developments, whatever their philosophical depth, depart from this path to different degrees.

This volume adopts an instrumental attitude toward Theravāda Abhidhamma, together with Buddhaghosa's Visuddhimagga. In an age exceedingly remote from arhatship, their analyses of mind and matter, cognitive processes, and stages of meditation provide one of the most systematic contemplative guides still available. This should be acknowledged and used well. What the volume rejects is their ontological narrative: analyzing "dhammas" down to the level of "ultimate dhammas" and attributing own-nature to them. Early scriptures do not state this move. It is a philosophical commitment advanced by the Abhidhamma system itself, and this volume treats it as the first substantive departure from the early teaching.

The three groups of judgments below all use the word attachment, so its meaning must first be defined. It refers to a structural inducement: what kind of clinging is encouraged by a system's combined formulation of problems, modes of argument, and institutional environment. The object of diagnosis is systemic structure, not the psychology of individual practitioners and still less the motives of the system's philosophers. To say that Madhyamaka contains an intellectual attachment is not to say that Nāgārjuna was attached to cleverness. It means that Madhyamaka's form of argument makes intellectual exertion easy to mistake for practice itself.

Madhyamaka is closer to pure philosophical assertion, an antimetaphysical metaphysical speculation. With the most exacting reductio arguments, it dissolves every view of intrinsic nature, yet ultimately develops the argument itself into an extraordinarily elaborate doctrinal system accessible only through extensive intellectual training. Within it lies a subtle attachment: attachment to intellectual activity itself. Arguments for emptiness become ever more refined and difficult until they form a game clever people delight in performing. Amid layer upon layer of argument, the cessation of suffering becomes distinctly secondary.

The mechanism of this attachment is easy to recognize among people engaged in metaphysical thought. Thinking always proceeds in the same way. It establishes an angle and explores it exhaustively, only to discover another angle. Once a line of thought settles, it makes itself its own object and adds another, "deeper" layer of reflection. Every advance brings genuine satisfaction, while a further reflection always beckons ahead, and thought can sustain itself without end. The experience is widespread among readers and especially gratifying to the "clever." Becoming absorbed in it is precisely the subtle attachment meant here. It is subtle because it disguises itself as diligence. Outwardly one appears to seek the path more deeply; in reality the pleasure of intellectual activity feeds itself and moves ever farther from suffering's cessation.

Yogācāra's attachment points in a different direction: attachment to a foundation, and to certainty of explanation. Human beings possess an almost irresistible desire for the "ultimate" and "fundamental." We continually ask "why" and "what is really happening," always wanting to know what ultimately underlies time, space, and consciousness. This desire resembles the self-sustaining reflection just described, but the two forms of depth differ upon closer examination. Intellectual attachment is recursive: thought repeatedly turns itself into an object, layer enclosing layer in self-similar and endless extension. Attachment to a foundation is iterative: it does not turn back upon itself but presses ever farther in the same direction, as though one further layer would touch the final bottom. The former has no end because it entangles itself; the latter because the "bottom" does not exist. Every thing identified as a "foundation" can itself be asked for its ground.

Attachment to a foundation is not distinctively Buddhist. An obvious parallel occurs in Abrahamic intellectual traditions, where "no first cause" is almost unacceptable. The cosmos must possess an unquestioned beginning or explanation has nowhere to rest. Desire for an ultimate ground is thus a general human tendency, independent of culture.

Yogācāra falls precisely under this tendency. It demands a logically coherent, fully interrogable mechanism for how all appearances arise, how seeds are perfumed, and how transformation of the basis occurs. The storehouse consciousness is therefore made to bear the entire explanatory weight of the arising of all phenomena. This mechanistic theory possesses rigor, but rigor itself almost becomes the purpose, as though liberation were guaranteed once the "foundation" had been explained.

A question deserves asking. If Abhidharma's "ultimate dhammas" had already prompted Madhyamaka's reflective checkpoint—Madhyamaka exists precisely to dissolve intrinsic nature in anything designated "fundamental"—how could Yogācāra still shape Buddhism so deeply? Madhyamaka was comparatively alert on this point and disposed to dissolve whatever was established as a foundation. Yet if attachment to a foundation is understood as one pressure, and Buddhist learning's self-perpetuating reflection as another force, their convergence makes the outcome intelligible. Even after Madhyamaka erected a checkpoint before ultimate dhammas, the impulse to find a positive, mechanized foundation remained strong enough to pass around it and open another route. Yogācāra's profound influence does not refute Madhyamaka's critique so much as demonstrate the tenacity of the attachment.

The tathāgatagarbha tradition appears most obvious: its attachment is to eternity. Buddha-nature, primordial purity, permanence, bliss, self, and purity positively answer questions about which early Buddhism intentionally remained silent—what lies beyond nirvāṇa, and whether anything permanent exists. The answer points precisely in the direction early Buddhism explicitly refused. Yet merely accusing the system of craving eternity does not go deep enough. Attachment to eternity is the other face of fear, and the fear here has two levels.

The first is shallow and universal. Human beings experience birth, aging, illness, death, and separation from loved ones. Impermanence alone is enough to disturb them, so they long for a heaven or eternal life as compensation. This layer of craving and fear is unexceptional; it is the shared background of nearly every religion promising eternity.

The second is far deeper and arises from early Buddhist soteriology itself. To many, its promised destination is not consoling but terrifying. Parinirvāṇa resembles an oil lamp whose fuel has been exhausted: the flame goes out and does not ignite again. After an arhat's body breaks up and life ends, one cannot say that the arhat is within the three realms, nor that the arhat has been reborn somewhere. The Buddha refuses every version of the question "does one exist or not after death," as the parables of the arrow and the fire to Vacchagotta illustrate. The supramundane is repeatedly called ineffable. To someone without direct realization who can only infer from words, nearly everything sounds like annihilation. The more rigorously early Buddhism maintains silence and refuses to describe nirvāṇa as some kind of "existence," the less room remains for this fear. Tathāgatagarbha's "permanence, bliss, self, and purity" directly answer it. The doctrine guarantees that what lies beyond extinction is not nothingness, but something primordially pure, constant, and indestructible.

There is another attachment concealed by the simple diagnosis "craving eternity." Tathāgatagarbha, simplifying over its several internal differences, contains not only an eternal object but an attachment to the guarantee of liberation, together with fear of liberation's uncertain path. Early Buddhism offers no warranty. Practice may not produce fruition in this life, the boundary between attainment and nonattainment is subtle, and practitioners must proceed alone through prolonged uncertainty. Tathāgatagarbha establishes the path's destination in advance as already accomplished: sentient beings are originally buddhas, pure and complete without seeking outside themselves. Practice changes from "whether one can arrive" to "how the inherent can be disclosed." This greatly relieves anxiety over uncertainty, but does so by setting a conclusion still awaiting verification as a premise. Tathāgatagarbha's attachment is therefore double: attachment to an eternal, indestructible object and to the certainty that "the destination is fixed."

These judgments will be argued separately in the introduction's Southern Buddhist chapter and the parts on Madhyamaka, Yogācāra, and tathāgatagarbha. The soteriologies of esoteric Buddhism and Pure Land will be assessed by the same standard in their corresponding parts. The conclusions are stated here so readers know the volume's position from the beginning.

One final qualification concerns the volume itself. Doctrinal criticism cannot exempt itself from its own analysis. Taking early Buddhism as a baseline can likewise be diagnosed as attachment: to origins, to simplicity, or to the critical posture itself. The volume does not evade the point but acknowledges it directly. Within early Buddhism's own framework, anyone who has not reached the state beyond training—arhatship, in which there is nothing further to learn and the taints are exhausted—necessarily carries one attachment or another. The person making these judgments has not reached that state, and this volume is no exception. To expect a work of doctrinal judgment to speak from a pure, unattached position is itself a misunderstanding.

The volume's only defense is not that it lacks attachment but that it identifies the direction of what it desires. Its doctrinal judgment is made from a position tending toward suffering's cessation and nirvāṇa. Its measure of each system remains "whether this helps suffering cease," not merely a ranking of doctrines and schools by superiority or intimacy. A doctrinal classification that only compares systems for rigor, harmony, or ultimacy merely replaces one intellectual preference with another. This volume seeks to make every judgment answerable to one thing: the cessation of suffering. Attachment may be unavoidable, but it can at least be directed toward the exit.
