The paper presents an analysis of the anumāna chapter of Jayarāśi’s Tattvôpaplava-siṁha and the nature of his criticism levelled against the anumāna model. The results of the analysis force us to revise our understanding of Jayarāśi Bhaṭṭa as a sceptic. Instead, he emerges as a highly critical philosopher. In addition, the nature of Jayarāśi’s criticism of the anumāna model allow us to conclude that anumāna should not be equated with inference, but rather is its limited subset, and may at best (...) be rendered as ‘disputational inference’, ‘debational inference’ or even ‘dialogical inference’. Jayarāśi applies a range of logical laws which clearly represent patterns of what can be classified as a priori reasoning and analytical justifications for knowledge, which were traditionally not reckoned sound. Against the backdrop of Jayarāśi’s criticism of anumāna, the paper also attempts to provide an explanation to why Indian philosophy and logic did not develop any concept of proper symbols and variables.

According to the Navya Naiyāyikas, inference is the knowledge, which is produced out of consideration. But what is to be understood by the term ‘consideration’ or ‘parāmarśa’? According to them, parāmarśa or consideration is the factor through the operation of which the inferential conclusion can be attained. Parāmarśa has been defined as the knowledge of the existence of the hetu or reason in the pakṣa or subject, which reason is characterized by its being concomitant with the sādhya, the knowledge in (...) the form of parāmarśa is actually caused by the knowledge of invariable concomitance of probans (hetu) with the probandum (sādhya) and the knowledge of the existence of the hetu in the subject (pakṣa). It has been said by Viśvanātha that the cognition of the existence of probans or hetu in the subject of inference along with the cognition of the prabans or hetu as pervaded by sādhya is called parāmarśa (pakṣasya vyāpyavṛttitvadhīḥ parāmarśa ucyate). The invariable co-existence in the form ‘where there is smoke, there is fire’ is known as vyāpti or invariable concomitance. Here the invariable coexistence (avyabhicārī sāhacarya) between the probans and probandum (i.e., smoke and fire) is the definition of vyāpti. The term ‘co-existence’ means remaining in the same locus of the probans with the probandum, which is not the counter positive of the absolute negation existing in the locus of the hetu. To Gangeśa, the knowledge of the co-existence of the probans and probandum along with the absence of the knowledge of deviation of the probans is the cause of ascertaining vyāpti. Repeated observations, of course, sometimes act as a promoter (prayojaka) in ascertaining vyāpti by removing the doubt of deviation. The doubt of deviation can be removed sometimes by Tarka or sometimes by the absence of the collocation of causes of doubt, which is called svataḥsiddhaḥ. Gangeśa admits sāmānyalakṣaṇā as a pratyāsatti in ascertaining vyāpti between smoke-in-general and fire-in-general. To him, the super-normal connection through universal (sāmānyalakṣaṇā pratyāsatti) has got a prominent role in ascertaining vyāpti. If somebody challenges about the validity of the syllogistic argument in the form “The mountain is fiery as it possesses smoke” (parvato vahnimān dhūmāt), the philosophers of Nyāya and Navya-nyāya persuasion will justify the same with the help of five constituents (avayava-s). The process is called parāthānumāna (syllogistic argument for making others understand). The constituents of a syllogism are proposition (pratijňā), reason (hetu), example (udāharaṇa), application (upanaya), and conclusion (nigamana). (shrink)

Nyana is the most rational and logical of all the classical Indian philosophical systems. In the study of Nyana philosophy, Karikavali with its commentary Muktavali, both by Visvanatha Nyayapancanana, with the commentaries Dinakari and Ramarudri, have been of decisive significance for the last few centuries as advanced introductions to this subject. The present work concentrates on inference in Karikavali, Muktavali and Dinakari, carefully divided into significant units according to the subject, and translates and interprets them. Its commentary makes use of (...) the primary interpretation in Sanskrit contained especially in the Ramarudri and Subodhini. The book begins with the Sanskrit texts of Karikavali and Muktavali; followed by English translation of these texts. Next is given the Sanskrit text of Dinakari which comments on the first two texts, followed by its English translation. Lastly, the book contains a commentary on all the texts included. (shrink)

Idealism is the core of the Pratyabhijñã philosophy: the main goal of Utpaladeva (fl. c. 925–950 AD) and of his commentator Abhinavagupta (fl. c. 975–1025 AD) is to establish that nothing exists outside of consciousness. In the course of their demonstration, these Śaiva philosophers endeavour to distinguish their idealism from that of a rival system, the Buddhist Vijñānavāda. This article aims at examining the concept of otherness (paratva) as it is presented in the Pratyabhijñā philosophy in contrast with that of (...) the Vijñānavādins’. Although, according to the Pratyabhijñā, the other subjects are not ultimately real since all subjects are nothing but limited manifestations of a single absolute subject, the fact that we are aware of their existence in the practical world has to be accounted for. The Vijñānavādins explain it by arguing the we infer the others’ existence. The Pratyabhijñā philosophers, while refuting their opponents’ reasoning as it is expounded in Dharmakīrti’s Santānāntarasiddhi, develop a particulary original analysis of our awareness of the others, stating that this awareness is neither a perception (pratyakṣa) nor an inference (anumāna), but rather a guess (ūha) in which we sense the others’ freedom (svātantrya).

The paper discusses anumāna and its variety in general from the point of view of inferential cognition for the sake of oneself as well as for the sake of others; i.e. svārthānumāna and parārthānumāna as given in the Buddhist tradition of logic, especially with parārthānumāna, its nature and role. The paper argues that the Buddhist intent of division of anumāna into svārthānumāna and parārthānumāna was to bring Buddha-vacanas under the category of parārthānumāna and to save them from being classified under (...) śabda pramāṇa. It contends that such a division was not just an epistemological demand, but had a deeper philosophical significance in the Buddhist conceptual framework. Such a division is, therefore, intended to reject the role of śabda as an extra causal means or pramāṇa. The paper identifies the logical commitment in Buddhist tradition as hetu-centric commitment as it differs from the Nyāya tradition of vyāpti-centric one. (shrink)

It is well known in contemporary Madhyamaka studies that the seventh century Indian philosopher Candrakīrti rejects the foundationalist Abhidharma epistemology. The question that is still open to debate is: Does Candrakīrti offer any alternative Madhyamaka epistemology? One possible way of addressing this question is to find out what Candrakīrti says about the nature of buddha’s epistemic processes. We know that Candrakīrti has made some puzzling remarks on that score. On the one hand, he claims buddha is the pramāṇabhūta-puruṣa (person of (...) epistemic and moral authority), sarvākārajñatājñānaṃ (omniscient, wise), pratyakṣalakṣaṇam (exclusively perceptual in characteristic) [Candrakīrti (MABh VI.214)], and claims that there are clearly four pramāṇas—epistemic warrants—direct perception (pratyakṣa), inference (anumāna), testimony (āgama) and analogy (upamāna) [Candrakīrti (Pp I.3), cf. MacDonald 2015, pp. 287–288]. On the other hand, somewhat paradoxically, Candrakīrti claims that buddhahood is an embodiment of a complete cessation of “mind and mental processes” [Candrakīrti (MABh XI.1, 155a; MAB XI.17d)] Now how are we to make sense of these two seemingly contradictory statements? Do these statements reflect any deeper conflicts within Candrakīrti’s system or is there a coherent way to interpret these statements? The Tibetan Prāsaṅgika interpreters of Candrakīrti’s Madhyamaka largely agree that there is no internal contradiction in Candrakīrti’s system, and agree there is a way to make coherent sense of these statements. Nevertheless, the Tibetans exegetes bring to the table two radically conflicting proposals to approach Candrakīrti’s Mādhyamaka; both claiming to successfully address the apparent tension arising from Candrakīrti’s statements. One proposal is made by Tsongkhapa Losang Dakpa (Tsong kha pa bLo bzang grags pa, 1357–1419), who maintains the tension can be plausibly resolved by demonstrating that Candrakīrti’s unique non-foundationalist epistemological program renders him an epistemological coherentist. In contrast Taktsang Lotsawa Sherap Rinchen (sTag tshang Lo tsā ba Shes rab rin chen, 1405–1477) argues that according to Candrakīrti buddha is a global agnostic, on the ground of the nonexistence of mind and mental processes for those who have attained fully awakening. Taktsang instead proposes the no-mind thesis as a more plausible way to resolve the tension in Candrakīrti’s philosophy, categorically refusing to attribute to buddha any cognitive processes and epistemic warrants. This paper is an analysis of Taktsang’s no-mind thesis—the claim that buddhas utterly lack any knowledge of the world because they do not have epistemic processes and warrants to perceive the world—in what follows a rational reconstruction of his arguments is developed in order to evaluate his thesis. We shall then assess the implications of accepting Taktsang’s no-mind thesis. (shrink)

Logic in Buddhist Philosophy concerns the systematic study of anumāna (often translated as inference) as developed by Dignāga (480-540 c.e.) and Dharmakīti (600-660 c.e.). Buddhist logicians think of inference as an instrument of knowledge (pramāṇa) and, thus, logic is considered to constitute part of epistemology in the Buddhist tradition. According to the prevalent 20th and early 21st century ‘Western’ conception of logic, however, logical study is the formal study of arguments. If we understand the nature of logic to be formal, (...) it is difficult to see what bearing logic has on knowledge. In this paper, by weaving together the main threads of thought that are salient in Dignāga’s and Dharmakīti’s texts, I shall re-conceive the nature of logic in the context of epistemology and demarcate the logical part of epistemology which can be recognised as logic. I shall demonstrate that we can recognise the logical significance of inference as understood by Buddhist logicians despite the fact that its logical significance lies within the context of knowledge.

Arthāpatti does not depend on observation of pervasion or background belief. It is certain in the sense that when S cognizes P through postulation, no other epistemic instrument would invalidate P. The Naiyāyika tries to reduce postulation to anumāna and/or tarka. I shall argue that it is neither. Due to its explanatory role, one may think that postulation plays an essential role in lakṣaṇā or indication. But this too is a misconception. Both tarka and lakṣaṇā depend on observation and background (...) knowledge. Neither of them has the epistemic certainty postulation enjoys. I think, due to its observation-independent nature and certainty, postulation can be seen as the source of the knowledge of the truths of reason. (shrink)

Although a number of authors have used diagrams extensively in their studies of Navya-Nyāya, they have done so to explain and illustrate concepts, not with the goal of reasoning with the diagrams themselves. Adherents of diagrammatic reasoning have made claims for its potential by pointing to key structural correspondences between diagrams and logical concepts, arguably lacking in sentential representations, and describing these relations using concepts such as “well matchedness” and “iconicity”. A canonical example of this iconicity is the use of (...) Euler diagrams to depict categorical syllogisms. Since the meaning of expressions in Indian logic differs in so many important ways from logic in the Western tradition, the use or adaptation of diagrams developed in the latter would seem to preclude iconicity. Thus, the development of diagrams which reflect the nature of inference in Navya-Nyāya, which centres on the anumāna inference schema, is motivated. In this paper we extend Ganeri’s method of depicting the Vaiśeṣika ontology with graphs to include syntax intended to expose the nature of anumāna. The diagrams are given a formal basis: i.e. abstract syntax, inference rules defined abstractly and a graph-theoretic semantics. These are the first formalised logical diagrams that aim to reflect the nature of the anumāna inference. This paper lays the way for further work in extending the formalism to cover more of Navya-Nyāya, and in exploring a dialogue between properties of the formalism and of Navya-Nyāya. (shrink)

A reasoned argument or tarka is essential for a wholesome vāda that aims at establishing the truth. A strong tarka constitutes of a number of elements including an anumāna based on a valid hetu. Several scholars, such as Dharmakīrti, Vasubandhu and Dignāga, have worked on theories for the establishment of a valid hetu to distinguish it from an invalid one. This paper aims to interpret Dignāga’s hetu-cakra, called the wheel of grounds, from a modern philosophical perspective by deconstructing it into (...) a simple probabilistic mathematical model. The objective is to understand how and why a vāda based on a probabilistically weaker hetu can degrade into a Jalpa or vitaṇḍā. To do so, the paper maps the concept of ‘Bounded Rationality’ onto the hetu-cakra. Bounded Rationality, an idea coined by the management thinker Herbert Simon, is often employed in understanding decision-making processes of rational agents. In the context of this paper, the concept would state that the prativādin and ālocaka (debater) may not hold unbounded information to back their pratijñā (proposition). The paper argues that within the probabilistically deconstructed hetu-cakra model, most people argue in the ‘Zone of Bounded Rationality’, and thus, the probability of a debate degrading into Jalpa or vitaṇḍā is high. -/- .

In Indian philosophy, a pramāṇa is an epistemic instrument or doxastic practice that results in a veridical cognition (in an event of knowing). For just about all Indian thinkers, perception (pratyakṣa) and inference (anumāna) are the foundational pramāṇas, although they debated energetically over how to characterize the content of the resultant cognitions and how to explain the basis for the authority of these pramāṇas. Debate also includes the relationship of knowledge to religious liberation, the role of scripture in knowing, and (...) the possibility of omniscience. (shrink)

This is a philological and critical analysis of two crucial philosophical concepts, viz., reaso and experienceâ. The study shows that, though there is no word in Sanskrit which may be taken as equivalent of Western reason and thought, such terms as tarka, yukti, nyaya, anumana, buddhi, etc., clearly capture parts or aspects of what is meant by reason and thought (Denken). Moreover, it is misleading to trans- late sruti as revelation. Construing sruti as revelation surreptitiously imports a Semitic theological (...) concept into the Vedic tradition. The case of experience is more promising because we have such Sanskrit words as anubhava or anubhuti that do translate into experience. However, experience in Western thought has acquired many shades of meaning, and the study determines in what sense the Indian anubhava captures the Western experience. Finally, the book demonstrates that Indian philosophy provides an account of the cognitive process that begins with perception and culminates in wisdom (highest experience). This whole process may be called reason, at both ends of which we can talk of experience, which places experience not in an external opposition to reason, but rather as something that belongs to it internally. Thus, the modern Western opposition between reason and experience collapses and the two toge-ther yield an integrated process of acquisition, validation, and practical application of knowledge.

This paper is a study of Bhartṛhari's understanding of the pramāṇas, i.e. the means whereby knowledge is acquired, as can be evinced from his Vākyapadīya and the corresponding commentary (Vākyapadīya Vṛtti). Both Bhartṛhari's general attitude towards pramāṇas as well as his specific understanding of the individual means of knowledge are analyzed. In particular, it is established that Bhartṛhari accepts exactly three pramāṇas: perception (pratyakṣa), inferential reasoning (anumāna) and tradition (āgama). However, the status of the three is unequal: perception and inferential (...) reasoning are fallible and hence cannot provide reliable guidance with regard to Dharma. These two pramāṇas do have their place and according to Bhartṛhari should not be discarded entirely. As for āgama, it is clear that Bhartṛhari accords it primacy in matters related to Dharma. But again, Bhartṛhari does not discard anumāna and pratyakṣa entirely. Rather, he seems to suggest that they have to be supplemented by āgama, which is the unimpeacheable judge of tradition.

The Bhagavad-Gita, as a multivalent text, has been a source of inspiration for all areas of Indian thought. This paper identifies elements in the Bhagavad-Gita which may have influenced the formation of Nyaya philosophy in the centuries after it was written. Part one of the paper reviews Nyaya epistemology as a whole, focusing on aspects that play an important role in the Bhagavad-Gita: perception (pratyaksa), inference (anumana), ‘syllogism’, verbal utterance (sabda) and the practical orientation of knowledge. The second part (...) shows how those aspects appear in the text of the Bhagavad-Gita. In praticular, Krishna relies on a number of techniques in convincing Arjuna of his obligation as a ksatria which would later be formalized in Nyaya philosophy as pramana or methods of knowing. As a whole, the Bhagavad-Gita also emphasizes the Nyaya view that knowledge is only useful insofar as it helps the knower achieve a particular goal. This paper does not, and has no pretention to prove the existence of a direct line of influence connection the Bhagavad-Gita and Nyaya philosophy; readers will instead gain an appreciation of the shared cultural context which gave rise to both of these forms of Indian thought. Abstrak Bhagavad-Gita, sebagai teks yang multitafsir, telah menjadi sumber inspirasi bagi segala pemikiran India. Makalah ini mengidentifikasikan unsur-unsur dalam Bhagavad-Gita yang mungkin memengaruhi pembentukan filsafat Nyaya selama beberapa abad setelah Bhagavad-Gita ditulis. Bagian pertama makalah meringkas epistemologi Nyaya secara keseluruhan dengan berfokus pada aspek-aspek yang memainkan peran penting dalam Bhagavad-Gita: persepsi (pratyaksa), penyimpulan (anumana), ‘silogisme’, saksi verbal (sabda), dan orientasi praktis pengetahuan. Bagian kedua memperlihatkan bagaimana aspek-aspek tersebut muncul dalam teks Bhagavad-Gita. Secara khusus, Krishna mengandalkan berbagai teknik dalam meyakinkan Arjuna akan kewajibannya sebagai ksatria yang kemudian diformalkan dalam filsafat Nyaya sebagai pramana atau sarana pengetahuan. Secara keseluruhan, Bhagavad-Gita juga menekankan pandangan Nyaya bahwa pengetahuan hanya berguna sejauh dapat membantu si penahu mencapai tujuan tertentu. Makalah ini tidak dapat membuktikan adanya garis pengaruh langsung yang menghubungkan Bhagavad-Gita dengan filsafat Nyaya; namun, kita tetap dapat mengapresiasi suatu ‘kemiripan keluarga’ di antara keduanya yang menunjukkan kekayaan konteks kebudayaan yang menghasilkan kedua buah pemikiran peradaban India ini.

Translation of a section of the Nyāyasūtra (and early commentaries) on the reducibility of arthāpatti (postulation) to anumāna (inferential reasoning). This includes NS 2.2.1-6, with the commentaries of Vātsyāyana, Uddyotakara, and Vācaspati Miśra.

The classical Indian Cārvāka (“Materialist”) tradition contains three branches with regard to the means of knowledge (pramāṇas). First, the standard Cārvākas accept a single means of knowledge, perception, supporting this view with a critique of the reliability and coherence of inference (anumāna). Second, the “more educated” Cārvākas as well as Purandara endorse a form of inference limited to empirical matters. Third, radical skeptical Cārvākas like Jayarāśi attempt to undermine all accounts or technical definitions of the means of knowledge (even perception) (...) in order to enjoy a life free from philosophical and religious speculation. These branches respectively present something akin to David Hume’s problem of induction, endorse a fallibilistic, mitigated skepticism, and embody a thoroughgoing skepticism about philosophy itself. While all three branches are skeptics about religious matters, each branch exemplifies a different variety of epistemological skepticism. (shrink)

Translation of a section of the Mānameyodaya dealing with the independence of arthāpatti (postulation) from anumāna (inferential reasoning).

In Indian philosophy, Bhāṭṭa Mīmāṃsakas and Advaita Vedāntins recognize abhāva or anupalabdhi (non-apprehension) as an independent source of knowledge; but no other school of Indian philosophy agrees with them on this issue, and for that reason, arguments have been given by the latter schools for rejecting anupalabdhi as an independent means of knowledge. In this paper, I am going to evaluate only those arguments which have been given by the Vaiśeṣika thinkers, who admit only two pramāṇa-s, viz. pratyakṣa and anumāna, (...) and reject anupalabdhi as an independent pramāṇa. There have been many scholarly studies dealing with the arguments against the reduction of non-apprehension to some other source of knowledge that have been offered by the Bhāṭṭa Mīmāṃsā and Advaita Vedānta, but there is hardly any full-length work that deals with the Vaiśeṣika’s reduction of non-apprehension to some other source of knowledge. In the present paper, an attempt has been made at providing a clear and specific account of the same. (shrink)

Paperback $19.00, isbn 978-1-62466-957-6.The scarcity of accessible English translations of Sanskrit texts (...) that retain the philosophical rigor of the original has been a great challenge in Indian philosophy. God and the World's Arrangement, a translation with introduction and explanatory notes by Nirmalya Guha, Matthew Dasti, and Stephen Phillips, is an example of how this scarcity could be addressed without straying away from present-day idioms and context. This book discusses the perspectives on God and the arrangement of the world according to Nyāya, Vedānta, Mīmāṃsā, and Buddhist philosophies. This book is divided into two parts, followed by two appendices, and a bibliography. Each part has study questions at the end and there is an impressive reading list. The first part is a translation and analysis of Śaṅkara's theistic argument in his commentary on the Brahma-sūtra 2.2.1–10. The translators also include the subcommentary by Vācaspati Miśra. The second part contains the translation and analysis of Vācaspati Miśra's theistic argument in his commentary on the Nyāya-sūtra 4.1.19–21. All translations are followed by explanations that elaborate the contexts of the arguments. The translations in this book are elegant and use modern English idioms.The seeds of this book were sown by a guest lecture by Nirmalya Guha to a philosophy course at the University of Texas at Austin. The other two authors joined hands with Guha and worked on texts from Sāṃkhya, Nyāya, Vedānta, and Buddhist schools of thought. Scholars around the world are now interested in having a pan-global view of philosophy. However, such an understanding requires an informed engagement with the various contexts and mores of thought. This deceptively slim volume addresses this problem by succinctly providing the required background context and clarifying many commonly held misconceptions about Indian philosophy, particularly Advaita Vedānta. For a long time, there have not been many serious readings of Advaita Vedānta texts. This book comes as a relief and explains the basic concepts of Advaita Vedānta with readings from relevant portions of texts like the Brahma-sūtra. This book is a step to fill the gap [End Page 1] of texts that properly voice the perspectives of scholars from within the traditions following Advaita Vedānta.It is heartening to read a contemporary text that acknowledges the unbiased masterly exegetical work of Vācaspati Miśra that earned him the epithet sarva-tantra-svatantra, "one who is equally proficient in all the disciplines of knowledge." The translators and editors of this book have a noble goal of "coupling Vācaspati's works on Vedānta and on Nyāya" to make "it possible for a wide swath of his work to be pondered, little of which is currently accessible despite Vācaspati's importance for the whole of classical Indian philosophical thought" (p. xi). The editors lose no time in clarifying the approach of the texts explained in the book from Vedānta and Nyāya philosophies. They explain in some detail one of the means of knowledge, pramāṇa s, used by the Indian philosophies that adhere to the Vedās, the means of anumāṇa or inference. An interesting aspect of this book is the contemporary examples that the translators give, like those of a politician and automobile manufacturers. For instance, the translators explain different ways in which arguments given through an example can fail. The translators explain the error of an example not having the property to be proved in this manner:Yet another type of failure occurs when the property to be proved is not actually present in the example.

Nyaya and Buddhism as the two-important traditions of Indian Philosophical Thought distinguished themselves through a detailed inquiry into various aspects of Anumana. In both the traditions there flourished a long chain of logicians of great reputation and profound scholarship. Particularly in the Buddhist tradition Dharmakirti distinguished himself, through his scholarly works, as a renowned logician and exerted influence alike both on his adversaries and followers. Although he has discussed a number of issues concerning Anumana in his different works, (...) no systematic attempt has been made to formulate and present Dharmakirti`s unified theory of Anumana in its various aspects. The present work undertakes to do this for the first time in the world of Buddhist scholarship. Giving a sketch of the conceptual framework of Dharmakirti`s philosophy by way of background, it discusses epistemic, constitutive and regulative conditions of Anumana according to him, and dealing with the validity and, or soundness aspects of Anumana along with Hetvabhasas it may give rise to, brings out their important implications not only for Dharmakirti`s philosophy but also for Buddhist philosophy in general.

It is commonly taken for granted that in Vedānta, as also in Indian philosophy in general, yukti, anumāna, and tarka, translate into “reason” (of Western thought) while śruti is rendered as “revelation.” I reject this translation-interpretation; it is a good example of theway in which Sanskrit philosophical discourse is often misconstrued. The term śruti does not refer to revelation, nor do yukti, anumāna, or tarka to reason. Reason, I argue, comprehends all the pramānas; these are all means of legitimizing beliefs. (...) I distinguish between different levels of the application of “reason,” and I maintain that the mere reasoner (tārkika) has not grasped the true nature of “reason.” In effect, I maintain that śabda, both lauika and alukika, is a component of reason, and so is perception. There is no concept of “revelation” in Indian philosophy, and no opposition between reason and experience. (shrink)

Buddhist logicians have rejected the reality of universals on the one hand, and, on the other hand, given a substitute in the form of the doctrine of Apoha. The doctrine of apoha first appears in Dinnaga’s Pramanasamuccaya, according to which words and concepts are negative by their very nature. They proceed on thebasis of negation. They express their own meaning only by repudiating their opposite meaning. The Buddhist logicians talk of two types of knowledge, viz., pratyaksa, which is non- relational (...) and anumana, which is relational. They accept nirvikalpaka pratyaksa as a pure pratyaksa, and savikalpaka pratyaksa has been merged with anumana by them. According to them, cognition is either a direct awareness of an object, which is independent of any mentalconstructionor it is an awareness of an object which is a mentalconstruction. Further, according to the Buddhist logicians inferences are of two kinds, viz., svarthanumana and pararthanumana. But they do not accept pararthanumana as a source of knowledge. Now, since perception is devoid of kalpana, perceptual knowledge is essentially non-linguistic and does not involve any general concept or universal. Thus,Apoha has no role to play in perceptual knowledge. On the other hand, savikalpaka pratyaksa and anumana are based on kalpana, thus according to the Buddhist logicians knowledge of universal is essential for both, savikalpaka pratyaksa and anumana.

This paper is in two parts. The first presents an analysis of the epistemology underlying the practice of classical Indian mathematical astronomy, as presented in three works of Nīlakaṇṭha Somayāji (1444–1545 CE). It is argued that the underlying concepts put great value on careful observation and skill in development of algorithms and use of computation. This is reflected in the technical terminology used to describe scientific method. The keywords in this enterprise include parīkṣā, anumāna, gaṇita, yukti, nyāya, siddhānta, tarka and (...) anveṣaṇa. The concepts that underlie these terms are analysed and compared with such ideas as theory, model, computation, positivism, empiricism etc. In a short second part, it is proposed that the primacy awarded to number and computation in classical Indian science led to an artificial language that did include equations but emphasized displays that facilitated calculation, as in the Bakshali manuscript (800 CE?). It is further argued that echoes of these concepts can be recognized in current science, where computation is once again playing a greater role triggered by spectacular developments in computer technology.

This paper restores the historical context of Milindapaha. The text is unique, because it is one of the very few documents of Ancient India, in which one of the authors is considered a Greek as a participant in the dialog. To reconstruct the context of the book, the basic archeological data about the Indo-Greek Kingdom, including epigraphics, are summed up, as well as there are analyzed some references to the kingdom given in the Mahāvaṃsa, the earliest chronicle of Sri Lanka. (...) These mentions in the Mahāvaṃsa are matched with the numismatics of Ceylon. From this analysis it is concluded that the document of Milindapaha was most likely created in Gāndhārī in the interval from the beginning of the 1st century B.C. to the end of the 1st century A.D., i.e. during the period of the domination of the syncretic culture of the North of India, combining Buddhism with certain elements of Hellenism. The treatise of Milindapaha was then preserved in Sri Lanka's tradition by continuing good political contacts with the Roman Empire after 400 A.D., that is, after the collapse of the Kushan and the Western Kshatrapas, the last dynasties that had previously preserved elements of Hellenism in the Indian subcontinent. The philosophical meaning of the treatise is then considered and it is concluded that in the text we can find direct references to the proto-Nyāya with the requirement to verify premises by examples. But the logical teaching of Milindapaha is far more archaic than the teaching of Nyāyasūtra, because only two sources of true knowledge are implicitly used: paccakkha and anumāna, and instead of the two verification methods called udāhārana and upamā, only one verification method called opamma is offered.
