Philosophy of Mind Map of the Triangular Dialogue Nyāya — enduring self • analysis of pramāṇa • precision about relations Buddhism — anātman • process continuity • debate over reflexive awareness Modern philosophy of mind — brain-dependence • embodiment • experiment • artificial intelligence (AI) Shared problem → different answers → testing by evidence → controlled comparison Problem Reading Nyāya, Buddhist philosophy and modern philosophy of mind together on questions of mind, consciousness and personhood is fruitful, but comparison here requires great care. Terms such as knowledge, consciousness, memory, self, subject, representation and cognition do not carry the same meaning in different traditions. Nyāya arguments concerning ātman, manas, the senses and episodes of cognition developed within their own metaphysics, epistemology and soteriological context; Buddhist accounts of anātman, momentariness, dependent origination, streams of consciousness and debates over reflexive awareness have their own historical and practical contexts; modern philosophy of mind raises its questions at the intersection of neuroscience, psychology, language, computation and analytic metaphysics. Treating similarity of words as identity of theories would therefore be a comparative error. The real question of this chapter is not which of the three is “right”. The question is how the three traditions differently open up shared difficulties concerning memory, experience, self-awareness, error, agency, consciousness and the validity of knowledge. The Parallel method constructs a dialogue at the level of problems while preserving historical difference. The first difficulty concerns the bearer of subjectivity. If there is cognition, whose cognition is it? Nyāya treats an enduring ātman as the substratum of qualities such as cognition, desire, aversion, effort, pleasure and pain. Many Buddhist traditions reject an enduring self and explain continuity through a causal stream, an aggregate-complex or a series of cognitions. In modern philosophy of mind, the self is variously understood as an enduring entity, a narrative construction, an embodied system, a self-model, or a practical person-level category. The second difficulty concerns intentionality—what is cognition about? Nyāya analyses object, qualificand, qualifier, relation and error with great precision. Buddhist epistemology offers distinct treatments of perception, inference, apoha, appearance and conceptual superimposition. Modern philosophy raises questions about mental content through externalism, representationalism, teleosemantics, predictive processing and enactivism. The third difficulty concerns reflexive awareness. How do we know our own cognition? In the Nyāya tradition, anuvyavasāya is a subsequent cognition that apprehends an earlier cognition. The debate over svasaṃvedana associated with the Dignāga– Dharmakīrti tradition raises the question of a cognition’s self-presenting aspect. Modern higher-order theories, accounts of pre- reflective self-awareness and metacognition also address this problem-axis. But none of these is simply the historical transformation of another. The fourth difficulty concerns memory and personal continuity. Nyāya explains continuity in memory, recognition and responsibility through an enduring self. The Buddhist counter-position attempts to explain memory and karmic connectedness through causal continuity without an enduring substance. Modern philosophy of mind examines the interrelations among memory, character, intention, bodily continuity and cerebral continuity. The fifth difficulty concerns error. Illusion, misperception, false belief and conceptual superimposition reveal much about the architecture of mind. Nyāya distinguishes the roles of object, qualifier, memory and relation in error. Buddhist thought emphasises distinctions between appearance and conceptual construction. Modern cognitive science examines such errors through priors, prediction error, confabulation and perceptual inference. The sixth difficulty concerns evidence. Mind is not a directly public object. First-person access to one’s own experience, the behaviour of others, linguistic reports, neural data, causal interventions and social context all possess different evidential values. Nyāya’s discipline of distinguishing pramāṇas, Buddhist epistemology and modern multi-method research open an important dialogue here. The seventh difficulty concerns ethics and personhood. If there is no enduring self, what grounds responsibility? If the self is distinct from the body, what is the ethical status of bodily vulnerability? If mental states depend on the brain, does agency disappear? The three traditions answer these questions differently; comparison should not erase their central differences but clarify them. Core Proposition The central proposition of this chapter is that the most fruitful dialogue among Nyāya, Buddhism and modern philosophy of mind should be based not on sameness of doctrine but on sameness of problem. Consciousness, cognition, error, memory, self- awareness, intentionality and evidence may form shared questions; ontology, soteriology, method and historical vocabulary must nevertheless be kept distinct. The Parallel method is not a project for proving genealogical origin. It does not claim that modern philosophy of mind emerged from Nyāya or Buddhist philosophy, nor that classical Indian categories had already anticipated the findings of modern neuroscience. The claim is only that independently developed philosophical traditions offer different conceptual resources for some similarly difficult questions. Nyāya’s principal strength lies in fine distinctions. Its analysis of the relations among ātman, manas, sense faculty, object, cognition, memory, desire, effort, pleasure, pain, absence and error is exceptionally discriminating. Navya-Nyāya makes this relational language even more precise. For modern philosophy of mind, the significance of this tradition lies not in declaring it “proto-analytic philosophy” but in its conceptual discipline. The principal strength of Buddhist traditions lies in their process orientation. The Buddhist critique of self sharpens the question whether a person is an enduring substance or a changing process linked by causes. The flow of aggregates, dispositions, memories, bodily states and social relations places pressure on the supposed necessity of an enduring self. Yet anātman should not be reduced to the slogan “self illusion”; it has ethical, causal, contemplative and soteriological contexts. The principal strength of modern philosophy of mind lies in empirical integration. Brain injury, neuroimaging, anaesthesia, split-brain cases, developmental psychology, psychiatric disorders, embodiment, computational modelling, artificial intelligence and cognitive neuroscience bring mental concepts before forms of evidence very different from the empirical basis of classical traditions. This evidence should not be forcibly imposed upon classical categories; it should serve instead as a test within dialogue. Principal Arguments First argument—the question “whose cognition?” lies at the centre of all three traditions, but the answers differ. Nyāya posits an enduring subject; Buddhist views emphasise causal streams or practical continuity of persons; modern embodied or functional accounts may emphasise organism-level or system-level organisation. The word “subject” should therefore not be assumed to have one universal meaning. Second argument—memory is not decisive proof of personal identity, but it is an important criterion of continuity. Nyāya strengthens the case for an enduring self by identifying the rememberer with the earlier experiencer. The Buddhist reply गजेन्द्र ठाकु रक समानान्तर दर्शन — खण्ड २ explains continuity through causal succession. Modern thought experiments involving memory transfer, amnesia and fission clarify the difference between identity and continuity. Third argument—recognition is not merely memory. When one judges “this is that very object”, previous experience, present perception and a judgement of identity are joined. Nyāya can use such cognition as support for an enduring subject; Buddhist criticism can accept earlier causal impressions while challenging the inference to an enduring self; modern cognitive science offers mechanistic explanations in terms of pattern recognition. Fourth argument—the Nyāya–Buddhist dispute over the structure of self-awareness opens a meaningful dialogue with modern metacognition. Anuvyavasāya explains awareness of a prior cognition through a subsequent cognition; svasaṃvedana emphasises the self-presenting aspect of cognition; higher-order representation, global availability and metacognitive access present different modern models. Fifth argument—a more useful question than “who came first?” is “which concept clarifies which problem more effectively?” Historical priority is a matter for source evidence; conceptual usefulness is a different criterion. Sixth argument—error is a mirror of mental architecture. Nyāya examines the substratum, object, qualifier, memory and relational defect involved in illusion. Buddhist thought questions conceptual superimposition. Predictive processing interprets perception through the interaction between prior expectations and sensory information. These accounts are not identical, but each opens the question of mental mediation. Seventh argument—first-person authority is not infallibility. We have special access to our own pain, desire and experience, but self-deception, confabulation, implicit bias and misdescription remain possible. The Nyāya–Buddhist debate over inner awareness can therefore enter fruitful dialogue with modern questions of self-knowledge. Eighth argument—third-person evidence is not self-sufficient either. A brain image does not automatically read out mental meaning; task context, behaviour, report, clinical circumstances and interpretation are required. Claims about mental states should therefore remain multi-evidential. Ninth argument—embodiment is present in Nyāya, Buddhist thought and modern philosophy of mind in different ways. Although Nyāya distinguishes the self from the body, it accepts a causal chain involving manas, sense faculties, body and object for cognition. Buddhist analysis of the aggregates shows the interdependence of form and mental factors. Modern embodied cognition makes the roles of environment and action still more explicit. Tenth argument—agency should not be understood merely as uncaused spontaneity. Desire, effort, habit, intention, bodily capacity, social constraint and causal history jointly constitute levels of agency. Nyāya’s analysis of effort, Buddhist accounts of conditioned action and modern action theory offer different resources here. Eleventh argument—the problem of other minds reveals the need for public criteria. Nyāya considers knowledge of another’s mental states through inference. Buddhist traditions open different contexts concerning behaviour, compassion and causality. Modern philosophy uses behavioural, linguistic and neural evidence. Artificial intelligence sharpens the problem further, because fluent language is not sufficient evidence of consciousness. Twelfth argument—technical vocabulary affects the interpretation of evidence. Calling every cognition a “mental representation” and every vijñāna “consciousness” destroys historical distinctions. Translation is not a neutral transfer; it is itself a philosophical hypothesis. Thirteenth argument—Nyāya’s theory of pramāṇa reminds philosophy of mind of its epistemological dimension. The question is not only “what is mind?” but also “how do we know claims about mind?” Questions of perception, inference, testimony and defeaters can enter meaningful dialogue with contemporary philosophy of science. Fourteenth argument—Buddhist dependent origination emphasises networks of dependence rather than enduring identity. Dialogue with dynamical systems, enactivism or process philosophy is possible, but doctrinal identity is not. Fifteenth argument—anātman does not entail ethical nihilism. If a person is understood as practical and causal continuity, suffering, responsibility, compassion and institutional accountability can remain meaningful. The same challenge appears in modern reductionist accounts of persons. Sixteenth argument—accepting an enduring self does not solve every problem. The relations of particular cognitions, memory- content, personality change, dementia, brain injury and unconscious processes to such an enduring self still require separate explanation. Seventeenth argument—brain-dependence does not establish reduction of the person to the brain. The empirical evidence that mental capacities depend on the brain is strong; the further conclusion that “a person is nothing but a brain-description” requires additional philosophical premises. Eighteenth argument—svasaṃvedana or reflexive awareness does not directly solve the hard problem of consciousness. “Experience is present to itself” and “why does experience arise from physical processes?” are two different questions. Nineteenth argument—artificial intelligence is a useful test case for the triangular dialogue. Nyāya-like questions include: what is the substratum of a cognition-claim, what is its object, what causes it, how does error occur, and what is the status of testimony? Buddhist-like questions include whether process-continuity without an enduring self is sufficient. Modern questions concern relations among function, structure, embodiment, report, affective value and consciousness. By these criteria, artificial intelligence should neither be immediately treated as a person nor dismissed without examination as a mere tool. Twentieth argument—an ecology of evidence is more appropriate than a hierarchy of evidence. First-person reports, behavioural performance, causal intervention, neural data, developmental history, social interaction and conceptual coherence play different roles. No single source is automatically final. Pūrvapakṣa First pūrvapakṣa: Nyāya accepts an enduring self while Buddhism rejects it; therefore real dialogue is impossible. The reply is that disagreement is not an obstacle to dialogue but its basis. Competing explanations of shared explananda such as memory, agency, error and continuity are precisely what make comparison worthwhile. Second pūrvapakṣa: classical Indian systems are religious or soteriological, whereas modern philosophy is scientific; therefore comparison is a category mistake. Part of the objection is correct—their historical aims differ. Yet classical philosophical claims concerning perception, inference, memory, language, self-awareness and reasoning remain comparable at the level of problems. Third pūrvapakṣa: after modern neuroscience, the ātman–anātman debate has become irrelevant. Neuroscience clarifies many questions of dependence, mechanism and correlation, but it does not automatically dissolve questions of personal identity, subjectivity, first-person authority, normativity and the metaphysics of consciousness. Fourth pūrvapakṣa: Buddhist anātman has been proved by modern cognitive science. This is an overstatement. Cognitive science may weaken many models of a fixed inner homuncular self, but the ethical and soteriological claims of Buddhist anātman are not a single scientific finding. Fifth pūrvapakṣa: Nyāya anuvyavasāya is an ancient form of higher-order theory. There is certainly similarity at the level of problem, but conceptual role, ontology, causal explanation, terminology and aim differ. Calling it a “precursor” without historical evidence is unwarranted. Sixth pūrvapakṣa: svasaṃvedana is exactly the same theory as phenomenal consciousness in modern philosophy. This too is an improper identity claim. Buddhist debate centres on the self-presenting character of cognition; the vocabulary and problem- structure of modern phenomenal consciousness are different. गजेन्द्र ठाकु र Seventh pūrvapakṣa: if the traditions are ultimately different, comparison is pointless. On the contrary, controlled comparison makes each tradition’s hidden presuppositions more visible. Nyāya raises the question of an enduring substratum, Buddhism challenges the necessity of enduring substance, and modern science introduces empirical constraints. Eighth pūrvapakṣa: Mithila is mentioned only for regional pride. If that were so, the objection would be justified. Mithila’s relevance in this chapter is not a claim of priority but the methodological discipline of pūrvapakṣa–uttarapakṣa, definition, relational analysis and testing by evidence. Uttarapakṣa First reply—comparison is not equivalence but relation. Similarity, difference, difficulty of translation and explanatory consequence between two concepts should be recorded separately. Second reply—three questions should be mandatory for every comparative claim: what is the historical source? what is the original technical meaning? and on which specific problem-axis is the modern comparison being made? This three-level test reduces anachronism. Third reply—do not dispose of Nyāya merely as a “substance theory”. Its broad traditions of classifying cognition, analysing error, testimony, inference, memory, desire, effort and language are highly relevant to philosophy of mind. Fourth reply—do not reduce Buddhist philosophy to the slogan “anātman”. Abhidharma theories of mental factors, Dignāga– Dharmakīrti epistemology, Madhyamaka critique, Yogācāra and debates over svasaṃvedana contain substantial internal plurality. Fifth reply—modern philosophy of mind does not speak with one voice. Physicalism, functionalism, representationalism, enactivism, higher-order theories, narrative theories of self, phenomenology, predictive processing and eliminativism disagree among themselves. Sixth reply—when a question is empirical, modern science supplies decisive constraints. But conceptual entailment, normativity and metaphysical explanation require distinct philosophical analysis. Seventh reply—treat first-person experience as evidence, not as infallible testimony. Treat third-person neuroscience as powerful evidence, not as a complete semantic explanation. Eighth reply—do not turn mental vocabulary about artificial intelligence into anthropomorphic shorthand. In statements such as “it understands”, “it remembers” or “it wants”, examine functional, structural, experiential and ethical meanings separately. Indian Dialogue The first condition of an Indian dialogue on mind is acceptance of plurality. There is no single Indian theory of self. Nyāya accepts an enduring ātman; Sāṃkhya distinguishes puruṣa from citta; Mīmāṃsā contains internal disagreement about the nature of the knower; Advaita offers a non-dual account of the witnessing self; Buddhist traditions present multiple forms of anātman and process-continuity; Jain philosophy develops a distinct ontology of jīva. The Nyāya–Buddhist dispute is especially useful because both sides offer subtle arguments about perception, inference, language, error and the validity of cognition while disagreeing profoundly about the self. The dialogue therefore produces genuine philosophical pressure rather than artificial similarity. Nyāya’s argument from memory has an intuitive force for an enduring subject: the one who experienced is the one who remembers. The Buddhist reply attempts to explain the ownership of “my memory” through causal continuity. Modern research on reconstructive memory, false memory, amnesia and neural change brings both arguments before new questions. Buddhist momentariness challenges the need for an enduring bearer, but it itself accepts the burden of explaining causal efficacy and continuity. Modern process accounts can provide contemporary analogues of this question, but not identity with karma or soteriology. The debate over reflexive awareness can become a centre of triangular dialogue. Nyāya anuvyavasāya, Buddhist svasaṃvedana, phenomenological pre-reflective awareness and modern metacognition present four different structures of “awareness of one’s awareness”. Mithila’s Parallel Perspective Mithila’s philosophical importance in this chapter is not a priority claim. Mithila has been an important region of Nyāya–Navya- Nyāya, Mīmāṃsā, commentary, śāstrārtha and scholastic traditions; but that historical fact does not justify the conclusion that “modern philosophy of mind was already present here”. Mithila’s Parallel contribution is principally methodological. For any cognition-claim ask: what is the substratum? what is the object? what is the qualifier? what is the relation? what is the cause? what is the counter-argument? what is the defeater? what is the status of absence? This relational discipline has a useful place in modern conceptual analysis. When local manuscripts, commentaries, scholastic lineages and printed editions are used, critical editing, dating, textual variants and source traditions must be made explicit. Regional pride is no substitute for source criticism. Developing a Maithili technical vocabulary is itself an epistemological task. Collapsing “mind”, “consciousness”, “self”, “awareness”, “cognition” and “representation” into one word destroys philosophical distinctions. Where necessary, the meanings of manas, citta, vijñāna, bodha, anubhūti, ātman, person, cognition and pratyaya should be distinguished explicitly. Mithila’s folk and literary experience is not an empirical substitute for philosophy of mind, but it can serve as a supplementary archive for understanding lived concepts of memory, grief, migration, dream, illness, relationship, personhood and identity. To use such material in philosophical argument, genre, context and independent corroboration are necessary. Evidence Ecology First-person experience • behavioural evidence • neural data • social context • conceptual coherence No single source is final — combined testing is necessary Contemporary Applications Clinical neurology of disorders of consciousness shows the limits and value of the triangular dialogue. It is risky to infer absence of consciousness merely from low external responsiveness. Behavioural testing, neural measurement, repeated examination and family testimony have different evidential values. Multi-evidential rationalism has practical importance here. Dementia sharpens the question of personal identity. A person does not cease to be a person merely because autobiographical memory weakens. Bodily continuity, affective response, social recognition, relationships and dignity reveal the limits of memory-centred theories. Nyāya offers one metaphysical answer through an enduring self; Buddhist process-continuity offers another kind of answer; modern ethics emphasises care and dignity. In psychiatry, it is not enough to dismiss a delusion or hallucination merely as a “false belief”. The structure of experience, trauma, neurobiology, social context and patterns of reasoning must all be examined. Nyāya analyses of error, Buddhist accounts of conceptual superimposition and modern psychology raise different questions here. An artificial-intelligence language model can produce fluent answers, use information from prior dialogue and generate self- referential sentences. But such behaviour does not by itself establish an experiential subject, an enduring self or consciousness. Independent evidence is required concerning structure, continuity, world-relation, agency, affective value, embodiment and causal integration. In digital identity, continuity of an account, biometric continuity and personhood are different questions. A password or online profile is not the person, yet digital records can profoundly affect social recognition, rights and reputation. A metaphysical self and an institutional identity must therefore be kept distinct. गजेन्द्र ठाकु रक समानान्तर दर्शन — खण्ड २ Brain–computer interfaces raise questions of mental privacy. Calling statistical interpretation of neural signals “thought reading” requires caution. Signal interpretation is usually an inference based on specified tasks and training; it is not direct access to the full contents of a mind. Nyāya’s discipline of inference can serve as a useful comparative resource for testing exaggerated claims of this kind. Meditation research requires particular care when Buddhist technical categories are used scientifically. When mindfulness, samādhi, vedanā, vijñāna or experiences of anātman are converted into psychological variables, the original philosophical context, differences among practitioners, validity of measurement and adverse effects should be recorded. Mere translation of a term does not establish full identity of experience. In legal responsibility, neural evidence does not automatically eliminate agency. Capacity, intention, compulsion, mental or neurological impairment, foreseeability of consequences and normative standards require separate examination. Causal explanation and moral or legal exculpation are not the same thing. In education, metacognition is a practical form of the question “knowledge of one’s own knowledge”. Students should develop the capacity to assess confidence in their beliefs, recognise error, test sources and revise answers. This is a useful modern application of reflexive cognition, but it should not be treated as a direct translation of classical anuvyavasāya or svasaṃvedana; the dialogue is at the level of problems. Chapter Conclusion The chief achievement of a triangular dialogue among Nyāya, Buddhism and modern philosophy of mind is not selecting a winner but making the questions more precise. Nyāya contributes precision concerning subject, relation, cognition, error and evidence. Buddhist philosophy contributes the challenge of process, impermanence, anātman, dependent continuity and reflexive awareness. Modern philosophy and science add embodiment, brain-dependence, computation, clinical evidence, artificial intelligence and experimental constraints. Declaring all three to be the same would damage philosophical history; treating them as wholly unrelated would squander a comparative opportunity. The Parallel method chooses the more demanding middle path—preserve historical differences, ask questions on shared problem-axes, distinguish levels of evidence, acknowledge the limits of translation, present opponents fairly, and keep conclusions corrigible. Chapter 81 maxim: “The same questions do not make the same theory; but sound comparison can reveal the hidden presuppositions of each theory.” गजेन्द्र ठाकु र PART XIII — SCIENCE, TECHNOLOGY, THE DIGITAL WORLD AND ARTIFICIAL INTELLIGENCE
