Non-Theistic Ultimate Reality

Abstract. Non-theistic ultimate reality names a family of philosophical answers to the question of what, if anything, possesses final metaphysical, explanatory, existential, or liberative significance when a creator deity is not presupposed. The family includes radically distinct models: the unconditioned in early Buddhist discourse, the emptiness of intrinsic nature in Madhyamaka, nondual Brahman in certain interpretations of Advaita Vedānta, the Dao as cosmic and practical way, the beginningless plurality of Jain ontology, and modern accounts of a self-explanatory natural order. These models disagree over substance, dependence, personhood, language, causation, the status of liberation, and the very legitimacy of positing a final reality. This monograph reconstructs their primary arguments and interpretive contexts, identifies the limits of familiar comparisons with Western theism, and examines the tendency to transform an account of ultimacy into an imagined universal metaphysical object. Its original analytical synthesis distinguishes five questions—ontological priority, explanatory termination, transformative liberation, normative orientation, and semantic limits—and tests how each conclusion depends on a tradition's substantive commitments. Comparative interpretations must preserve the doctrinal work performed by source terms and identify openly where a new interpretation changes that work. The resulting thesis is that non-theistic ultimacy constitutes an internally diverse field of rational positions rather than a single doctrine of impersonal divinity. Its deepest philosophical achievement is to separate the question of what is basic from the question of what saves, and both from the question of what human language can adequately describe.

Introduction

The historical study of philosophy of religion has often organized its most general question around divine existence: whether God exists, whether divine attributes cohere, and whether a divine being can account for the world. The question of ultimate reality has a wider logical scope. It asks what claim, condition, entity, pattern, or achievement could be fundamental in a sense that matters to an entire view of existence. The shift changes the form of the inquiry. Instead of beginning with an assumed set of divine attributes and evaluating candidate bearers, philosophy must investigate how different intellectual traditions formulate finality, necessity, dependence, and human fulfillment.

The expression non-theistic ultimate reality is initially a classificatory instrument. It marks an inquiry that can proceed without accepting a personal creator as its premise. It does not by itself establish that ultimate reality exists, that there is a single ultimate, that all forms of religion seek the same object, or that whatever is ultimate must be impersonal. Those claims are separate arguments requiring evidence. In particular, the absence of a creator in a doctrinal system can coexist with celestial beings, devotional practices, profound philosophical commitments, and systems of cosmology. Conversely, a philosophical account expressed with the word God may reject an anthropomorphic creator model. Non-theism is therefore best treated as a question about the explanatory and doctrinal roles of deity, not as a shortcut from a name to an ontology.

A comparative method becomes necessary because the familiar candidate expressions are in tension. Early Buddhist discourse characterizes the unconditioned in relation to a path of liberation (R01–R02). Nāgārjuna's Madhyamaka challenges the reification of independently existing natures and makes the conception of an ungrounded final object problematic (R03–R06). The Chāndogya Upaniṣad articulates the primacy of being and nonduality, whereas Advaita interprets that inheritance through a complex relationship between Brahman, self, consciousness, and Īśvara (R07–R08). Classical Daoist texts connect the Dao to namelessness, cosmic formation, spontaneous process, and guidance, without simply reproducing either Buddhist emptiness or Vedāntic selfhood (R09–R11). Jain philosophy exhibits yet another possibility: a cosmos without a supreme creator that nevertheless retains irreducibly different substances (R12).

The research problem is consequently twofold. First, which arguments make a non-theistic conception of the ultimate philosophically intelligible? Second, how can one compare such conceptions without replacing their distinctive structures with a supposedly neutral Western category? A successful answer requires close reading of specific textual propositions, conceptual reconstruction, attention to interpretive conflict, and explicit separation of descriptive scholarship from the present author's philosophical synthesis.

The central thesis of this dossier is that ultimacy is a role-sensitive predicate. A doctrine may call something ultimate because it explains derivative entities, because it marks the cessation of suffering, because it constitutes what exists in a final ontological description, because it orders practical conduct, or because it fixes the limits of predication. These roles can coincide, but their coincidence must be argued. Their separation makes visible the possibility of a genuine non-theistic metaphysics and the possibility of a non-theistic practice for which an independent ultimate substance is the wrong theoretical expectation.

Research Object and Method

The object is the philosophical construction and justification of ultimate reality in systems that do not require a personal creator deity. The inquiry concentrates on concepts with established primary texts or identifiable philosophical traditions. It examines early Buddhist soteriological ultimacy, Madhyamaka anti-foundationalism, Advaita nonduality, Jain pluralistic cosmology, Daoist cosmic and practical order, Spinoza's substance metaphysics as a boundary comparison, and modern analytic questions concerning grounding and religious pluralism. These cases were selected for the distinct logical solutions they offer, not because they represent every school within their parent traditions.

The method has five stages. Historical-textual reconstruction establishes the proposition actually advanced in a document and the problem it addresses. Conceptual analysis then identifies its truth conditions, its dependence claims, and the philosophical work performed by decisive terms. Comparative analysis asks whether proposed similarities preserve these commitments. Critical reconstruction tests arguments against objections that arise within and across traditions. Finally, original synthesis presents a classificatory framework whose claims are expressly attributed to this monograph.

The evidence base is differentiated by access. Directly inspected digital passages include Udāna 8.3, Saṃyutta Nikāya 43, Chāndogya Upaniṣad 6.2.1, the Daodejing, Part I of Spinoza's Ethics, and The Mystical Theology of Pseudo-Dionysius. For the Mūlamadhyamakakārikā, the crucial Sanskrit of chapter 24, verse 18 and its translation were inspected in an accessible scholarly article; the 2013 Siderits–Katsura edition was bibliographically identified through publisher and library records, rather than represented as a complete examined book (R03–R04). Interpretations beyond these passages draw upon inspected scholarly entries and articles whose individual access level is specified in the research evidence register. John Hick's monograph and some journal papers were accessed through publisher descriptions or abstracts; detailed chapter claims have not been attributed to an unseen full text (R17–R19).

Translation constitutes a conceptual problem. The Sanskrit terms brahman, śūnyatā, svabhāva, and pratītyasamutpāda, the Pāli asaṅkhata and nibbāna, and Chinese dào and zìrán should be retained where translation is materially contested. Their English counterparts serve as provisional explanations. The very term reality carries metaphysical associations that cannot be presumed to be present in an early Buddhist or Chinese text in the same sense. No single English gloss is used as evidence of philosophical identity.

This is philosophical research based on public textual and scholarly evidence, not an empirical experiment or an assessment of whether liberative experiences objectively prove a metaphysical doctrine. The results concern the conceptual validity, coherence, comparative structure, and historical intelligibility of arguments. Claims about the precise spiritual efficacy of a path remain the claims of the traditions under study. Historiographical dating is limited to responsibly corroborated ranges; no legendary biography is treated as a verified historical event.

The Conceptual Grammar of Ultimacy

The adjective ultimate is relational before it becomes absolute. A final cause is final relative to a causal inquiry; an ultimate end is final relative to a ranking of purposes; an ultimate constituent is basic relative to a decomposition; and an ultimate truth is final relative to the criteria used in an inquiry. To move from one use to another, a philosopher requires an additional proposition. An argument that dependent things require a ground does not immediately establish that this ground is good. An argument that liberation is the highest end of a practice does not establish that liberation is a cosmic material substance.

At least five functions recur. Ontic ultimacy identifies a constituent or structure with metaphysical priority. Explanatory ultimacy identifies a point where a why-question is satisfactorily answered. Soteriological ultimacy describes a condition or realization that completes liberation. Normative ultimacy identifies the supreme orienting good or way of life. Semantic ultimacy concerns what can be said of what is taken to be fundamental. Modern comparative work explicitly distinguishes the most real, the most valuable, and the most fulfilling, while also debating whether such a broad concept distorts the traditions it brings into relation (R15). The present fivefold analysis separates explanation from ontology and semantic limits from norms, making two additional argumentative distinctions.

These functions permit an essential question: does ultimacy attach to a thing, a fact, a relation, a process, a condition, an act of realization, or the dissolution of a misleading distinction? A theory of substance can postulate a self-subsisting whole; a theory of dependent origination can expose the incoherence of any such independent bearer; a soteriology can call cessation final without turning it into an object among other objects. The grammatical subject of an ultimate assertion may thus have radically different ontological status in different propositions.

The difference between logical priority and temporal priority is equally important. A principle can be described as prior to the world without having existed in an earlier episode of cosmic history. The text of the Daodejing can say that the Dao is before Heaven and Earth while also raising the problem of naming and spontaneous order. A theory of metaphysical grounding may be atemporal: facts about one entity hold in virtue of facts about another, without the latter causing the former at some earlier date (R09, R16). Reading priority as a pre-cosmic event introduces a premise which the text or argument may not require.

Nor does final explanation automatically produce a unique entity. A pluralist can hold that several fundamental categories are uncreated, a monist that a single whole grounds its parts, and an anti-foundationalist that explanatory dependence need not terminate in a substance. The burden of proof falls on the claim that the ordering of explanations is well founded and admits precisely one terminal member. Contemporary grounding theory debates both well-foundedness and uniqueness; the philosophical vocabulary of ultimacy must preserve that openness (R16).

The Historical Problem of Non-Theistic Classification

The opposition of theism and atheism has been shaped by particular controversies over personal creatorhood, worship, providence, and divine attributes. Applying those categories to every Asian philosophical school risks confusing several questions. Whether a system rejects a first creator is different from whether it recognizes deities within a cosmos; whether it recognizes deities is different from whether any deity is the ultimate ground; and whether it uses the language of transcendence is different from whether transcendence names a personal agent.

Buddhist texts can describe celestial beings while making liberation depend on insight, conduct, and the cessation of craving, rather than the decree of a supreme creator. Jain philosophy rejects a creator above an eternal cosmos yet recognizes souls and other real categories; the label atheistic in some comparative accounts records the rejection of cosmic creation, not a universal rejection of spiritual realities (R12). Daoism has both classical philosophical writings and later religious traditions involving deities, rituals, revelations, and lineages (R10–R11). Its historical diversity defeats any simple equation of Daoist ultimacy with a modern secular naturalism.

Advaita presents an even sharper classificatory challenge. The proposition that Brahman is nondual does not entail that the tradition is straightforwardly nonreligious. Śaṅkara incorporates Īśvara into his philosophical account and is read through devotional and monastic lineages. The issue is whether ultimate Brahman is interpreted as a personal creator, as non-intentional consciousness, or as a reality from which conventional divine-personal descriptions are philosophically distinguished (R08). Non-theistic is therefore applicable only to specified interpretations and philosophical functions, rather than to Vedānta as a monolithic whole.

A final historical caution concerns the noun ultimate. There are comparable questions across traditions, but the English academic category is a modern instrument of comparison. It can illuminate without erasing local questions, provided its interpretive operations remain visible. Comparative analysis begins with the problem each text actually attempts to solve and reaches shared categories through explicit reasoning. It does not assume that all traditions secretly refer to one homogeneous reality.

Early Buddhist Discourse: The Unconditioned

Early Buddhist statements about nibbāna supply a form of ultimacy centered on release from conditioned existence. The Udāna 8.3 speaks of what is unborn, unbecome, unmade, and unconditioned, and directly connects that characterization with the discernibility of escape from what is born and conditioned (R01). The argumentative relation in the passage is significant. Its claim is not framed as a cosmological derivation of finite things from an eternal maker. It establishes that liberation from conditioning is intelligible and available within the teaching's scheme.

Saṃyutta Nikāya 43 intensifies the practical interpretation. In the opening discourse of the Asaṅkhata-saṃyutta, the unconditioned is characterized in connection with the ending of greed, hatred, and delusion; a path leading to it is then specified (R02). The text thus unites a negative description of conditioning with a transformative criterion. An interpreter who treats this term simply as another name for an eternal world-substance must explain why the discourse defines it through the cessation of dispositions and through practice.

There are several ways to understand the relation of nibbāna to existence. One reading emphasizes the unconditioned as distinct from conditioned processes; another warns that language of distinctness can mislead when interpreted as a spatial second world or a bearer of properties analogous to a physical object. The primary texts in the present evidence base support the claims of an unconditioned and of a path to cessation. They do not, taken alone, settle every later Abhidharma debate about ontological status. Responsible interpretation therefore distinguishes the scriptural assertion, the later philosophical ontology, and the comparative metaphysical extrapolation.

The category also demonstrates why non-theism should not be reduced to negation. The practical and conceptual system is full of affirmative commitments: an account of suffering, a path, causal and ethical connections, and a criterion of its cessation. Its rejection of the explanatory role of a creator does not leave an empty philosophical space. It places ultimate concern within the transformation of the relation between experience, desire, ignorance, and liberation.

An objection arises that if something is unconditioned it must be a simple, eternal entity. That conclusion depends on an additional premise: every intelligible unconditioned must be a positive object bearing permanence. The Buddhist discourse itself does not establish this universal premise. The description can function as a limit on conditioned production and as the characterization of cessation. Here metaphysical restraint is part of interpretive accuracy: the source establishes the indispensable role of the unconditioned for the stated path, while its exact entity-status remains a further philosophical question.

Madhyamaka: Emptiness Without a Final Substance

Madhyamaka makes one of the most radical contributions to the philosophy of ultimate reality by questioning the independent self-nature that a final substance is usually supposed to possess. Nāgārjuna's Mūlamadhyamakakārikā examines causation, motion, agency, identity, knowledge, and other categories to undermine accounts that grant them intrinsic, autonomous existence. Svabhāva, variously rendered intrinsic nature or inherent existence, is the key target; śūnyatā indicates the emptiness of such independent nature (R05–R06).

The pivotal chapter 24, verse 18 identifies dependent origination with emptiness and dependent designation, and articulates the middle way through this relation. Its Sanskrit has been reproduced and discussed in an accessible scholarly treatment of Nāgārjuna's two truths (R04). The philosophical achievement is more exact than a blanket denial of the world. Dependently existing things can participate in ordinary causation and language. What is denied is the additional claim that these things are independently founded in an essence immune to dependence. The world remains the field in which transactions and reasons operate.

Consider a conventional object, such as a clay vessel. Its existence is tied to materials, processes, uses, parts, designation, and practices of identification. One could say that a fundamental clay particle grounds the whole. Nāgārjuna's line of inquiry presses further: the supposed particle, its causal powers, and the relations that individuate it are themselves vulnerable to dependence analysis. If an object depends even conceptually on a mode of designation, its independent self-establishment is suspect. The analysis challenges a final object conceived as independent in every respect, not merely one proposed constituent.

The argument is sometimes represented as a doctrine that emptiness itself is the ultimate substance. That formulation risks reversing the analysis. If emptiness were a self-subsistent ontological material, the challenge to intrinsic nature would spare precisely what it claims to examine universally. Contemporary scholarship explicitly discusses how the theory of emptiness avoids becoming a new intrinsic ground and how its own use may be corrective and context-sensitive (R05). The question is also contested by interpreters of the two truths and later Buddhist traditions; the present study identifies the philosophical pressure rather than announcing a single interpretation as universally accepted.

The causal argument deserves special care. Dependence is often treated as evidence that a thing lacks intrinsic self-sufficiency. Yet the inference from causal dependence alone to dependence in every conceivable sense requires separate support. Some Buddhist Abhidharma theories accepted causally produced dharmas while assigning them intrinsic nature, a distinction analyzed in the current Nāgārjuna scholarship (R05). Madhyamaka's most ambitious conclusions therefore depend on complex arguments concerning conceptual establishment, explanatory practices, and the coherence of svabhāva. A one-sentence appeal to interdependence cannot replace those arguments.

The resulting kind of non-theistic ultimacy is paradoxical only when ultimacy has already been defined as an independently existing supreme thing. If ultimacy instead concerns the most penetrating clarification of how phenomena can be understood and how mistaken attachment can be overcome, emptiness can occupy an ultimate role without functioning as an ultimate substance. This difference is central to the original comparative framework developed below.

The Two Truths and the Problem of an Ultimate View

The conventional and ultimate truths are indispensable to Madhyamaka interpretation, but the language of two truths must be read within its argumentative environment. Conventional truth addresses the functioning of ordinary language, practical transactions, and intelligible distinctions. Ultimate analysis exposes the failure of self-subsistent natures. The relation raises an exact difficulty: if ultimate truth is described as an independent description of reality apart from every conceptual frame, that description can itself appear to claim the very intrinsic status which Madhyamaka challenges (R05–R06).

One response is to distinguish the truth of a corrective practice from a timeless metaphysical proposition about a separately existing realm. A physician's diagnosis can be true and indispensable without constituting an eternal substance. Likewise, an analysis of empty phenomena can transform inquiry without positing emptiness as a stand-alone thing. This analogy is limited: the historical Buddhist dispute concerns the status of truth and liberation, not merely the utility of a practical instrument. Still, the analogy exposes why the demand for an ultimate object may misidentify the issue.

The interdependence of the two truths also changes the meaning of transcendence. Transcendence can describe the overcoming of distorted conceptual fixation rather than physical departure to a higher ontological location. The distinction is philosophical rather than a psychological measurement. It does not empirically certify the transformative claims of Buddhist practice; it explains how an apparently negative analysis can possess a soteriological function.

An interpretive disagreement remains. Some scholars read Nāgārjuna as developing context-sensitive anti-realism, others defend versions of realism that distinguish the absence of intrinsic nature from the nonexistence of mind-independent phenomena. The Stanford treatment explains the stakes of these alternatives and rejects the idea that a single master argument can mechanically settle every form of svabhāva (R05). A recent 2025 study also examines competing textual and commentarial readings of MMK 24.18, including the Chinese and Sanskrit traditions, and thereby demonstrates that even a canonical sentence has a history of disputed attribution and syntax (R19). The full article was accessed at the level of its publisher's abstract; this monograph does not claim to have resolved its detailed philology.

There is a broader lesson for comparative inquiry. A doctrine can make the limits of ontological hypostatization central to its account of liberation. Any comparative vocabulary that forces it to identify an autonomous ultimate entity has already decided against it before the interpretation begins. A sound comparison must allow a theory in which the very demand for a final substance is the problem under examination.

Advaita Vedānta and Nondual Brahman

Chāndogya Upaniṣad 6.2.1 articulates an early source of nondual reflection by speaking of being as one without a second. The passage appears within Uddālaka's instruction of Śvetaketu and is inseparable from a larger educational sequence concerning the underlying reality of apparent multiplicity (R07). It establishes a background for later Advaita, while the doctrinal sophistication of Śaṅkara's metaphysics should not be silently projected backward as if the Upaniṣadic passage were a complete eighth-century treatise.

Classical Advaita Vedānta develops the relation between Brahman and ātman, reading the fundamental reality of things and the deepest understanding of self through nonduality. Scholarship on Śaṅkara identifies his view of ātman as pure non-intentional consciousness, numerically identical with Brahman, and describes liberation through the recognition of this nondual identity (R08). The position joins ontic ultimacy to a form of epistemic and soteriological transformation: ignorance sustains the mistaken perception of plurality as independently final, while knowledge discloses the significance of what is fundamentally real.

The analogy with Madhyamaka is tempting because both criticize everyday metaphysical appearances. The difference is decisive. Advaita can assert a nondual real principle, while many Madhyamaka interpretations explicitly challenge the search for an independent foundational reality. The terms nondual and empty therefore cannot be made synonymous without reconstructing each tradition's account of identity, dependence, consciousness, and knowledge. In one case the apparent many are read against an underlying nondual reality; in the other, the analysis of appearances can undermine the assumption of an underlying entity.

The presence of Īśvara in Advaita compounds the classification problem. Śaṅkara's system includes reflection on God as well as on Brahman; it is also situated within historical religious institutions and traditions. The formulation of nirguṇa Brahman as beyond qualifying properties does not establish that the entire school is atheist or devoid of deity (R08). A non-theistic reading applies to the logical role of impersonal or non-intentional ultimacy in certain philosophical reconstructions. It should remain explicitly qualified in doctrinal discussions.

The individual self also has a different status in Advaita and Buddhist traditions. The Upaniṣadic–Advaitic identification of ātman and Brahman cannot be equated with the Buddhist critique of enduring self. A claim that both teach the same ultimate by different names would need to reconcile an affirmative identity involving ātman with traditions for which positing such a metaphysical self is mistaken. Similar ethical or contemplative aspirations do not alone provide that reconciliation.

Advaita thus establishes that non-theistic features can exist within a system involving religious language and divine models. Its central philosophical challenge is to explain how nondual knowledge relates to a world of differentiated experience and why the movement from everyday plurality to ultimate nonduality should be rationally compelling. Those questions belong to its own theory of superimposition, knowledge, and reality, not to an assumed universal mystical identity.

Jain Pluralism and the Uncreated Cosmos

Jain philosophy supplies a corrective to the temptation to equate the absence of a creator with metaphysical monism. Its ontology includes multiple fundamental categories: souls, matter, motion, rest, space, and time. The IEP's account describes a cosmos whose fundamental constituents are uncreated, while a creator deity standing over the whole is denied (R12). The model is therefore non-theistic with respect to the cosmic creator question and pluralistic with respect to the inventory of what exists.

This structure unsettles a familiar argument. One may reason that the universe cannot be self-sufficient unless it rests on a single, all-inclusive source. The Jain picture presents an alternative logical possibility: several irreducible categories can belong to an eternal world-order without being generated by a personal creator. Whether this alternative is ultimately persuasive depends on arguments for the substances and their relations. Nevertheless, the conceptual possibility shows that creator rejection neither entails a single Absolute nor implies that all ontology is merely conventional.

Jain discussions of standpoint and the many-sidedness of reality further complicate assertions of final description. A complete account must respect different aspects of things and avoid treating partial statements as exhaustive. The commonly used term anekāntavāda is important to this tradition, but this dossier does not infer its detailed canonical formulation from a single modern summary. The present argument relies on the verified scholarly description of Jain ontology, while primary textual and philological analysis of the Tattvārtha-sūtra and individual Jain commentaries would constitute a separate dedicated research task.

A philosophical advantage of the Jain comparison is its independence from the binary of personal deity versus impersonal one. It supplies a third general structure, namely noncreated plurality. The corresponding difficulty is the explanation of order among several basic realities. If they interact, the relations between them need analysis; if they are co-eternal, the necessity or contingency of their co-existence remains a question. Their being uncreated does not automatically make them each explanatorily complete.

The Jain case therefore illustrates the difference between chronological beginninglessness and metaphysical self-explanation. An eternal cosmos may contain uncreated categories while still inviting questions about why those categories and laws are as they are. Such questions are legitimate, but a demand for a creator follows only if the premises of a creator argument have first been established. Jain philosophy belongs in a complete account of non-theistic ultimacy because it preserves robust ontology without accepting a singular creating person.

Daoism: The Dao, Naturalness, and the Ten Thousand Things

The Daodejing offers a conceptual vocabulary in which the Dao is prior to, pervasive of, and implicated in the flourishing of the ten thousand things. Chapter 25 describes an unnamed, difficult-to-characterize source associated with the formation of the cosmos, names it Dao provisionally, and connects the human way, earth, heaven, Dao, and naturalness. The Chinese source text and an established English translation are available through the Chinese Text Project (R09). The text's point cannot be captured merely by replacing Dao with the English word God or with the scientific term physical law.

Chapter 1 introduces a related tension between the Dao that can be spoken and the constant Dao. It presents naming as philosophically significant. If the supreme term of an ontology is subject to the same fixity and definitional capture as ordinary things, its alleged ultimacy may have been lost in the act of conceptualization. At the same time, the Daodejing uses language extensively to guide conduct. It is therefore insufficient to describe Daoism as a refusal of all discourse. The question is what kind of discourse fits a changing, generative, and normatively significant world-order.

Current scholarship emphasizes the historical variety of Daoist interpretations. A recent Stanford account frames classical Daoism around natural ways and possibilities, and records the movement from disputes about social guiding paths to a broader understanding of natural unfolding (R10). A separate examination of religious Daoism documents the development of ritual, cosmological, and divine dimensions, together with the role of the Daodejing and Zhuangzi within lineages (R11). These perspectives are not interchangeable, and the modern distinction between philosophical and religious Daoism should not be projected as a self-evident ancient boundary.

Dao as ultimacy can perform several functions. It provides a conception of origin or background order; it offers a model of transformation and return; and it orients practical action through naturalness, spontaneity, and an appropriate relation to circumstances. The translation of zìrán as naturalness, self-so, or spontaneity affects the interpretation. A claim that Dao is an eternal static thing may conflict with passages that emphasize ongoing process; a claim that it is only practical advice ignores its cosmological reach.

The comparison with Madhyamaka has real points of contact: suspicion of rigid naming, resistance to coercive conceptualization, and attention to relational patterns. Yet their argumentative projects differ. The Madhyamaka critique of svabhāva develops through specific dialectical arguments concerning dependence and intrinsic nature. The Daodejing often employs compressed cosmological images and practical counsel. Similar language of namelessness does not establish a shared ontology or a historical line of direct doctrinal identity.

An interpretive danger also arises in treating Daoist naturalness as identical to contemporary naturalism. The Daoist category combines cosmology, ethics, cultivation, and historical textual traditions. Modern philosophical naturalism normally invokes public scientific explanations and debates about the completeness of physical or natural reality. A disciplined comparison can show structural analogies while preserving this divergence of reasons, institutions, and evidential standards.

Spinoza: Substance, God, and Nature

Spinoza is a boundary case because his central metaphysical term is explicitly God, yet his account departs sharply from a picture of a divine craftsman external to the created world. Part I of the Ethics defines substance as what is in itself and conceived through itself, and God as an absolutely infinite substance. Proposition 14 argues that no substance can exist or be conceived besides God; Proposition 15 holds that whatever exists is in God and cannot exist or be conceived without God (R13). The structure is a philosophical argument about substance, attributes, and modes, not a conventional narrative of world-creation.

The relation of God and Nature in Spinoza has long encouraged pantheistic and naturalistic interpretations. Nonetheless, classification must attend to the entire argumentative system. It would be inaccurate simply to say that Spinoza denies God, because his Ethics makes God indispensable. It would be equally misleading to infer that his God is a deliberating personal creator acting through contingent choices. The more useful comparative question concerns divine agency: which characteristics of a personal maker does a philosophical system actually assign to its absolute?

In Spinoza's framework, ontological priority is asserted strongly. Substance is conceived through itself, while modes are conceived through something else. This makes Spinoza more congenial to substantialist grounding than an anti-substantialist reading of Madhyamaka. The example confirms that two systems can reject a familiar personal creator while occupying opposed positions on whether ultimacy is an independent substance.

There is a valuable logical pressure here. If substance is self-conceived and modes are dependent, how does the completeness of a single substance account for concrete differentiated reality? Spinoza develops answers through attributes, modes, and necessity. The present study restricts its textual claims to inspected definitions and propositions in Part I, while using the case as a comparison of models rather than a full reconstruction of all five parts of the Ethics. This prevents an inference about ethics or political philosophy from being attributed to an unexamined passage.

Spinoza marks a limit of the simple division between theistic and non-theistic reality. The material question is whether ultimate existence must be personal, whether it acts intentionally, and how finite things follow from it. A name alone cannot settle these issues. The same terminological discipline should be applied to Brahman and Dao: their translation into a Western divine idiom is an argument that requires defense, not a neutral dictionary substitution.

The Apophatic Boundary

Negative theology provides a crucial counterexample to the proposition that what exceeds ordinary description must be non-theistic. In The Mystical Theology, Pseudo-Dionysius describes a divine cause beyond ordinary affirmation and negation. The accessible English edition connects this language explicitly to God, divine causality, and the theological ascent (R14). The denial that God can be adequately named is an internal form of theism, not automatically its abandonment.

A comparison can now distinguish at least three kinds of conceptual limit. An apophatic theologian may preserve a divine referent while denying that finite categories capture it. A Daoist text may present naming as provisional in relation to a cosmic and practical way. A Mādhyamika may criticize the very supposition of intrinsic nature in the object of ultimate designation. All three constrain language, but they differ in what their constraints are intended to protect or dissolve.

This distinction reveals a recurring error: to infer ontological identity from rhetorical similarity. Formulas such as beyond words, beyond concepts, or unsayable are too indeterminate to support identity claims. One must ask what the speaker asserts about causation, personhood, dependence, selfhood, religious practice, and the relation between language and realization. A shared limit on predication can accompany incompatible ontologies.

The apophatic case also illuminates a substantive question about thought. If the ultimate is said to outrun all concepts, what entitles a philosophical system to predicate even existence or ultimacy of it? The answer may lie in a disciplined distinction between affirmative discourse, negative discourse, and transformative use. However, the details must be argued within each tradition. Unqualified appeal to ineffability can protect any thesis from criticism; therefore it cannot serve as a general exemption from the demand to explain the meaning and use of a claim.

Naturalistic Ultimacy and Grounding

A non-theistic ultimate need not be religious. Contemporary metaphysics asks whether some entities, structures, facts, or laws are fundamental and whether dependence chains terminate. The debate on metaphysical grounding distinguishes constitutive determination from ordinary temporal causation and examines whether a ground must itself have a ground (R16). It offers conceptual instruments with which to articulate a self-sufficient physical order, a fundamental network of relations, or a non-terminating series of dependencies.

Suppose a philosopher claims that the natural universe is all there is. This is a completeness thesis about ontology. It does not yet establish that the universe has a single fundamental constituent, that its laws could not have been otherwise, or that its existence explains itself. Naturalism and explanatory ultimate status thus need separate articulation. A physicalist may describe high-level facts as grounded in physical facts while holding that the fundamental physical facts are brute. Another naturalist may postulate that a relational structure, rather than a collection of small objects, is basic. These positions belong to an active metaphysical debate; no laboratory result by itself determines the philosophical form of complete explanation.

The principle of sufficient reason presents a familiar difficulty. If every fact requires an explanation, an ungrounded ultimate appears to be an exception. One option is to restrict the principle to contingent facts; another is to explain the ultimate through necessity; a third is to reject the unrestricted demand for explanation. Each has a philosophical cost. Restricting the principle raises the question of which facts qualify; necessity claims require modal justification; and rejecting complete explanation can leave genuine questions unresolved. Non-theism inherits rather than dissolves these problems.

The theory of grounding also warns against a simplistic termination argument. An infinite dependence chain may be deemed vicious, but the vice has to be specified. If a complete account could consist of an interconnected or infinitely structured pattern, the absence of a single bottom item would not automatically refute the account. Conversely, not every infinite sequence is an adequate explanation merely because it is mathematically coherent. The relevant issue is whether the proposed structure discharges the explanatory demands that prompted the inquiry (R16).

A practical and ethical temptation follows: because the natural order is all that exists, one should revere it or conform to it. This inference is invalid without additional normative premises. Ontic completeness by itself does not imply moral supremacy, existential consolation, or a duty to imitate nature. The distinction is especially important when a comparative author moves between Buddhist cessation, Daoist attunement, and physicalist explanation under a single heading of ultimate reality. Those concepts supply different kinds of reasons.

Pluralism and the Postulate of a Common Real

Modern philosophical pluralism responds to religious diversity by asking whether apparently incompatible traditions can nevertheless relate to one transcendent or ultimate reality. John Hick's An Interpretation of Religion, published in 1989, is a major example. Its publisher describes an account of historically conditioned religious responses to transcendent reality; the present study draws this general characterization from the publisher record, not from a complete inspected edition (R17). Contemporary accounts of ultimacy also discuss the alternatives of a shared core, family resemblance, and strong particularism (R15, R20).

The comparative attraction is evident. If traditions differ dramatically in images, doctrines, and practices while generating recognizable forms of transformation, a common ultimate may seem to explain their convergence. But the inference has two steps that must be defended. First, one must show that the relevant achievements are sufficiently alike to count as evidence for a common explanatory object. Second, one must show why the best explanation is one independent transcendent reality rather than shared human problems, overlapping philosophical structures, historical interaction, or parallel uses of language.

The common-Real hypothesis faces a special Buddhist objection. If a school rejects self-established natures, to stipulate an independent Real behind its language may substitute another metaphysics for the one the school actually argues. An Advaitin can object differently: a Real whose relation to self and nondual consciousness is unspecified is too thin to preserve the central doctrine. A Jain pluralist can ask why the plurality of basic categories should be subordinated to a single hidden referent. A Daoist can ask whether the postulate turns the movement and naturalness of Dao into the fixed object that naming was supposed to handle with caution.

The objections do not prove that dialogue is impossible. They show why comparison must preserve the formal structure of positions and the practical criteria by which traditions assess their claims. Family resemblance may provide a better initial method than identity, because it allows multiple forms of overlap without demanding a common bearer. A taxonomy can register that a tradition is concerned with liberation, fundamental reality, or meaningful orientation while leaving its ultimate commitments distinct.

Religious diversity also poses an epistemic question: how should conflicting traditions be assessed when their proponents disagree over what counts as evidence? Historical texts, logical argument, contemplative practice, testimony, and ethical consequence have different evidentiary roles. A respectful comparison does not make all claims true. It identifies standards of justification, examines where claims are compatible, and states the remaining incompatibilities. The pluralism debate is therefore a problem of rational adjudication as well as interreligious hospitality.

Comparative Logic: Five Functions of the Ultimate

The reconstructed cases permit five different analytical tests. The ontic test asks what the theory says exists fundamentally and whether that item or structure is one, many, or unfit for substance predicates. The explanatory test asks which relations of dependence are recognized and whether the theory claims a terminal explanation. The soteriological test asks whether a condition, realization, or practice transforms the problem that motivates the doctrine. The normative test asks whether ultimacy prescribes a way of living. The semantic test asks what kinds of predication or naming remain legitimate.

Early Buddhist discourse scores most clearly under the soteriological test: the unconditioned is presented in relation to release, and SN 43 connects it with the cessation of greed, hatred, and delusion (R01–R02). Its explicit passages also have an ontological vocabulary, but their argumentative emphasis prevents an automatic classification as substance monism. Madhyamaka places exceptional weight on the ontic and semantic tests by criticizing intrinsic nature and on the soteriological test by connecting insight to liberation (R05–R06).

Advaita puts nondual ontic priority, the epistemic relation of ātman and Brahman, and liberative knowledge in an integrated structure (R07–R08). Jain ontology demonstrates a plural fundamental inventory without a creator, so its ontic commitments cannot be converted into monism (R12). Daoism brings together cosmic order, natural unfolding, and practical orientation, while its language of naming modifies the terms of conceptual access (R09–R11). Spinoza makes substantialist ontic priority and logical explanatory dependence especially prominent (R13).

Modern naturalist grounding theories foreground the explanatory test. They may or may not assign ultimate value to their fundamental facts; a philosophical model that does not claim to save or guide should not fail merely because it lacks those functions. A philosopher can coherently reject all soteriological models and still ask which facts ground the rest. By the same reasoning, a contemplative tradition can make liberation fundamental without undertaking the project of contemporary fundamental physics.

The five tests reveal a structural asymmetry. To call something ultimate in one role requires a reason internal to that role; to assert that the same thing is ultimate in several roles requires linking arguments. This is the crucial distinction between a family resemblance classification and a universal theory of a single Absolute. It allows philosophically informative generalization while preserving precisely those differences on which real disagreements depend.

Arguments for Non-Theistic Ultimacy

The argument from explanatory sufficiency begins from the possibility that the existence and structure of reality can be accounted for without positing an intentional creator. If a theory specifies sufficient constitutive or causal conditions for the phenomena under investigation, a further agent is not licensed merely by the absence of a religious narrative. This argument is conditional: explanatory sufficiency must be demonstrated within the domain and may leave questions about totality, necessity, or the existence of the conditions themselves. Its force lies in requiring a positive justification for additional explanatory commitments.

The argument from ontological economy states that theoretical entities should earn their place through explanatory work. A cosmic personal agent introduces determinate predicates such as intention, knowledge, freedom, and agency. A model that grounds the relevant phenomena in impersonal substance, relational structure, or natural laws may be preferable when those predicates produce no additional explanatory advantage. Parsimony alone does not prove that the impersonal theory is true, because simplicity must be balanced against adequacy. It does show that theistic agency cannot be treated as an automatic property of anything fundamental.

The argument from dependence analysis starts with the vulnerability of allegedly self-subsisting objects to their constitutive relations. Madhyamaka develops this pressure in its critique of svabhāva, suggesting that a final, independent thing can be a projection of the explanatory grammar being criticized (R05). The generalizable conclusion is modest but important: the move from conditioned phenomena to an unconditioned independent bearer is an inference, not a self-evident rule of rational thought. Some positions may reject the move without refusing explanation itself.

The argument from transformative adequacy begins from religious systems whose primary problem is suffering, bondage, or misorientation. If a practice's account of liberation makes sense within a network of cognition, conduct, and cessation, a creator hypothesis may be extraneous to the problem as formulated. The early Buddhist texts provide a concrete case (R01–R02). The argument does not establish experimentally that liberation occurs, nor does it settle disputes about the ontology of nibbāna. It establishes that a concept can have ultimate significance in an organized philosophical practice without being a creator.

The argument from plural fundamental categories opposes the idea that rejecting a creator forces the theorist into radical reductionism. Jain ontology offers an intellectually serious alternative involving several basic substances (R12). Plurality and independence remain disputable, but their conjunction with creator denial is coherent as a proposed metaphysical architecture. Non-theistic ultimacy thus includes both monistic and pluralistic models.

An argument from epistemic restraint adds that if the evidence does not justify assigning intentional predicates to the source or order of things, one ought not claim those predicates on conceptual grounds alone. This principle does not amount to a proof that no deity could exist. It is a rule concerning the warrant of specific claims. It also applies against unwarranted non-theistic metaphysical certainties: an impersonal Absolute must be defended, and an assertion of sheer nothingness must be defended, by reasons appropriate to its content.

Objections, Rival Readings, and Methodological Risks

A first objection says that any ultimate must be divine by definition. This is a legitimate stipulation within a specified theology, but it cannot establish a universal result in comparative philosophy. A definition restricted to a deity eliminates counterexamples by vocabulary while leaving the substantive question untouched. The philosophical task is to identify whether there are sufficiently general roles of fundamental explanation or final fulfillment that different traditions can occupy without presupposing divine personhood (R15).

A second objection says that the non-theistic ultimate is a disguised God. This is sometimes plausible for particular accounts, especially where an Absolute receives attributes of providential governance or a comprehensive agency. But the claim requires a precise attribute analysis. To equate nibbāna with a divine creator, or emptiness with a metaphysical person, would need arguments missing from the defining passages. Spinoza demonstrates the converse complication: the explicit name God can be embedded in a substance system that differs from personal creationism (R13).

A third objection alleges that Madhyamaka emptiness is nihilism. The objection ignores the conjunction of dependent origination and emptiness in MMK 24.18, and the sustained discussion of convention and practice (R04–R06). The antithesis of intrinsic nature is not the denial that conventional phenomena function. However, this defense must be formulated without reintroducing emptiness as an intrinsically existing correction. The doctrine contains its own methodological challenge: what enables the claim of emptiness to be taught and evaluated if its concepts are themselves dependently established?

A fourth objection concerns internal consistency across traditions. If an Advaitin asserts a real nondual ground and a Mādhyamika denies self-established nature, can their views both be true? They cannot simply be declared equivalent. Their disagreement may involve different meanings of reality, but semantic variation alone is insufficient to dissolve contradicting propositions. Only a detailed reconstruction of the conditions under which each thesis is asserted could establish compatibility. The present monograph preserves this as a genuine theoretical divergence.

A fifth objection challenges comparisons built from translated terminology. English reality, nothingness, self, and consciousness can suggest misleading ontological pictures. The Chāndogya's sat, the Buddhist asaṅkhata, and Daoist dào cannot be treated as interchangeable lexical units. The discipline required is to identify the inferential relations each expression supports: what follows from its affirmation, what it excludes, and what transformation its use intends to induce. Where this study has accessed an excerpt rather than a complete critical edition, that limit is recorded rather than concealed.

A sixth objection challenges the authority of a philosophical taxonomy devised outside the traditions. A comparative scheme can reproduce a hierarchy hidden in the researcher's vocabulary, privileging explanatory grounding over contemplative realization or the reverse. This study addresses the risk by refusing to rank its functions and by specifying comparison as a map of commitments rather than a verdict that all traditions instantiate one doctrine. The comparative scheme remains a research choice, open to correction by a more precise account of a primary text.

The most serious general objection is that the category non-theistic ultimate reality itself is too wide to be informative. If it groups nearly any world-picture without a creator, it threatens to become a residual category. The answer is to require more than creator denial: the system must make a substantive claim concerning final ontological status, explanatory basis, liberative completion, authoritative orientation, or the limit of predication. The claim must play a central role in the argument or practice. This necessary condition distinguishes the studied models from the mere absence of a theological proposition.

Original Synthesis: Comparing Functions and Commitments

The comparative evidence supports a more precise reading of an ultimate claim when five aspects are examined together: (1) the function a proposed ultimate performs; (2) the ontological commitments its defense requires; (3) the arguments supporting those commitments; (4) the practical or explanatory criteria by which the position is assessed; and (5) the alternatives that the position excludes. These considerations organize the interpretation developed here. They are authorial analytical choices drawn from the preceding cases, not categories attributed to classical authors or presented as a new theoretical system.

The first comparative question asks why a candidate is ultimate. Consider the unconditioned: its significance in the examined Buddhist passages is bound to the possibility and achievement of cessation. Consider substance in Spinoza: its significance derives from being in itself, conceived through itself, and the basis for modes. These different functions can be expressed within a comparative structure without reducing one to the other.

The second question concerns ontological commitments. They may include a single substance, multiple eternal categories, an account of dependent phenomena without intrinsic nature, an impersonal source, or a limit concept that resists objectification. These descriptions are deliberately heterogeneous because their heterogeneity is the philosophical problem. A researcher who writes merely ultimate = impersonal reality has omitted the commitments needed to make the comparison valid.

The third question reconstructs inferential support. In a metaphysics of substance, one may begin from definitions and demonstrations about what can be conceived independently. In Madhyamaka, one may begin from dialectical examination of the coherence of intrinsic nature. In early Buddhist discourse, one may begin with a teaching about conditioning, its cessation, and the path. Each form of reasoning has conditions of validity and interpretive context. The comparison of conclusions without inferential routes is philosophically impoverished.

The fourth question concerns the success criterion. Explanatory models must answer the relevant why-questions, while transformative models aim at liberation, practical orientation, or the overcoming of ignorance. The criterion itself can be disputed; it is not made true by the tradition's assertion. Its explicit presence prevents a soteriological teaching from being mistakenly scored only by its ability to account for the structure of elementary particles, or a naturalist cosmology by its ability to confer spiritual release.

The fifth question specifies exclusions. An account of emptiness may exclude self-existing essences; a Jain ontology may exclude a single creator of the eternal cosmos; Spinoza's substance argument excludes additional independently existing substances; an apophatic theology may exclude the adequacy of ordinary predicates without excluding the divine referent. Attending to exclusions reveals incompatibility while keeping comparison informative.

Applying these questions across the cases yields a comparative result. The familiar set of non-theistic ultimates is neither uniformly monistic nor uniformly anti-realist, neither uniformly naturalist nor uniformly mystical, and neither entirely world-affirming nor entirely world-negating. Their recurring feature is that fundamental explanatory or existential work can be performed without the premise of an intentional creator. The differences among their ontological and practical mechanisms are constitutive of the field, not accidental exceptions.

Interpretive Fidelity Across Traditions

Historical and philosophical fidelity require a comparison to preserve the central inferential, ontological, and practical commitments through which a concept functions in its source tradition. When a substitute term changes those commitments, the change becomes the interpreter's own philosophical proposal and requires an independent defense. The reason for this demand emerges from the cases already examined: verbal similarity can obscure differences between liberation, dependence, substance, natural unfolding, and apophatic reference.

For example, translating Dao as cosmic order can be heuristically useful, but a reduction to invariant physical laws would omit the text's treatment of naming, naturalness, and practical life. Translating śūnyatā as nothingness could erase the argument that empty phenomena arise dependently and are conventionally intelligible. Calling Brahman impersonal matter would displace Advaita's distinctive relation between consciousness, self, knowledge, and nonduality. Calling Spinoza's substance a personal craftsman would conflict with the precise roles of substance and modes in the Ethics.

This interpretive concern also governs formal argument. If model A posits an ungrounded substance and model B treats the attribution of intrinsic existence as misconceived, a comparison cannot report that both posit the same Absolute merely because both discuss the ultimate. That statement suppresses their contradicting commitments. It may instead report that both address the finality question, but A answers with independent being while B interrogates the demand for such being.

Such care leaves room for productive philosophical synthesis. One can propose a theory drawing from Buddhist dependence and Daoist naturalness, or from Jain plurality and contemporary grounding, but the resulting construction becomes a new theory with its own premises. It cannot be attributed backward to historical figures. Intellectual originality and historical fidelity are therefore compatible when transformations and provenance are clearly identified.

The same evidentiary obligation applies to this monograph. Its five questions and accompanying comparisons are authorial interpretations, not quotations from the Udāna, Nāgārjuna, Śaṅkara, or the Daodejing. Their merit depends on their clarity, consistency, fidelity to primary-source commitments, and philosophical usefulness. They remain revisable in light of new philological and comparative research.

Implications for Philosophy of Religion

The first implication is curricular and classificatory. Philosophy of religion should treat non-theistic metaphysical and soteriological systems as central material, alongside arguments for and against a personal God. A complete account of religious thought must be able to ask what functions as ultimate even when the answer takes the form of an impersonal order, a plurality of uncreated categories, a nondual reality, a practice of cessation, or a critique of independent substance. This expands the field's philosophical questions without dissolving their rigor.

The second implication concerns philosophical method. Comparative work should explicitly identify whether it studies first-order ontology, explanatory dependence, soteriology, practice, semantics, or the relations among them. Researchers should be willing to conclude that two traditions disagree substantively. Their difference can itself yield philosophical knowledge, because it reveals unexamined assumptions in concepts such as existence, substance, self, ground, liberation, and ultimate good.

The third implication is epistemic. A text's assertion that realization is liberating is evidence for the tradition's philosophical doctrine and internal criterion, not automatically scientific verification of an experience. Similarly, the validity of a metaphysical demonstration cannot be established by pointing to historical popularity or contemporary spiritual attraction. Source criticism, conceptual inference, and empirical evidence play different roles. Their relations need justification rather than rhetorical blending.

The fourth implication concerns naturalism. A complete naturalistic ontology is compatible with multiple theories of fundamentality and normative life, and the absence of divine agency does not settle questions about a sufficient explanation of the universe. Thus naturalism belongs in a wider comparative discussion, but remains intellectually distinct from the religious and contemplative traditions whose propositions about liberation and practice carry additional commitments.

The fifth implication concerns language. Namelessness and ineffability should be studied through the uses and effects of a tradition's discourse. Negative theology can remain theistic; Buddhist emptiness can reject reification; Daoist writing can employ provisional names within a practical-cosmological philosophy. The appearance of verbal similarity is the beginning of analysis, never its end.

Finally, the method offers a research architecture for future dossiers. The Nature of Religious Reality, God and the Divine, Pantheism and Panentheism, Naturalism and Theism, and related ontological studies can each examine a distinct cluster. Their eventual cross-references should preserve one canonical research identity per subject and link only actually published pages. No future article or unpublished dossier is represented here as an existing public destination.

Conclusion

Non-theistic ultimate reality is a coherent and irreducibly plural philosophical research field. The examined traditions demonstrate several independent ways for a conception to be final without relying on a personal creator: cessation as the completion of a path; emptiness as the critique of self-subsistent nature; nondual reality as the basis of knowledge and liberation; an eternal plurality of categories; Dao as a source and way of natural unfolding; and a self-contained substance or natural order proposed as the ground of its derivative expressions. These are distinct accounts with genuine differences in their ontologies, arguments, and standards of success.

The inquiry establishes four conclusions. First, creator denial alone is insufficient to define an ultimate doctrine; a substantive conception of metaphysical, explanatory, liberative, normative, or semantic finality is required. Second, what is ultimate under one function need not be ultimate under every other function. Third, arguments for an independent final substance cannot be assumed to govern systems that question intrinsic existence. Fourth, the interpretation of religious plurality is strongest when shared questions are distinguished from asserted identity of answers.

The comparative questions developed in the analysis make systematic evaluation possible while protecting the philosophical work performed by source terms. They allow systematic research without treating every tradition as a variation of one imagined Absolute. The monograph's original analytical contribution is an argued interpretation of ultimacy as a plurality of roles accompanied by demonstrable and contestable ontological commitments. The enduring question is therefore not only what reality is in the last analysis, but also which kind of last analysis is appropriate to the question being asked.

The field remains open in the productive sense of philosophical inquiry. New critical editions, deeper comparative philology, formal accounts of grounding, and specialized studies of Buddhist, Jain, Vedāntic, and Daoist schools will refine the proposed map. The present monograph establishes its conceptual structure, source-grounded cases, major objections, and original synthesis as a finished individual research work for scholarly and editorial review.
