Trairūpya
''Trairūpya (''Sanskrit; English: "the triple-character of inferential sign") is a conceptual tool of Buddhist logic. The Trairūpya, ‘three conditions’, is often accredited to Dignaga (c. 480-540 CE) though is now understood to have originated with his teacher Vasubandhu (fl. 4th century) in the ''Vāda-vidhi'', post-reconstruction of this work by Erich Frauwallner, Frauwallner (1957). Trairūpya is a logical argument that contains three constituents which a logical ‘sign’ or ‘mark’ (linga) must fulfill to be 'valid source of knowledge' (pramana): #It should be present in the case or object under consideration, the ‘subject-locus' (pakṣa) #It should be present in a ‘similar case’ or a homologue (sapakṣa) #It should not be present in any ‘dissimilar case’ or heterologue (vipakṣa) When a ‘sign’ or ‘mark’ (linga) is identified, there are three possibilities: the sign may be present in all, some, or none of the sapakṣas. Likewise, the sign ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buddhist Logic
Buddhist logico-epistemology is a term used in Western scholarship to describe Buddhism, Buddhist systems of ' (Epistemology, epistemic tool, valid cognition) and ' (reasoning, logic). While the term may refer to various Buddhist systems and views on reasoning and epistemology, it is most often used to refer to the work of the "Epistemological school" (Sanskrit: ), i.e. the school of Dignāga, Dignaga and Dharmakirti which developed from the 5th through 7th centuries and remained the main system of Buddhist reasoning until the Decline of Buddhism in the Indian subcontinent, decline of Buddhism in India. The early Buddhist texts show that the Gautama Buddha, historical Buddha was familiar with certain rules of reasoning used for debating purposes and made use of these against his opponents. He also seems to have held certain ideas about epistemology and reasoning, though he did not put forth a logico-epistemological system. The Theravada ''Kathāvatthu'' contains some rules on ...

Vasubandhu
Vasubandhu (; Tibetan: དབྱིག་གཉེན་ ; floruit, fl. 4th to 5th century CE) was an influential Indian bhikkhu, Buddhist monk and scholar. He was a philosopher who wrote commentary on the Abhidharma, from the perspectives of the Sarvastivada and Sautrāntika schools. After his conversion to Mahayana, Mahayana Buddhism, along with his brother, Asanga, he was also one of the main founders of the Yogacara school. Vasubandhu's ''Abhidharmakośakārikā'' ("Commentary on the Treasury of the Abhidharma") is widely used in Tibetan and East Asian Buddhism, as the major source for non-Mahayana Abhidharma philosophy. His philosophical verse works set forth the standard for the Indian Yogacara metaphysics of "appearance only" (''vijñapti-mātra''), which has been described as a form of "epistemological idealism", Phenomenology (philosophy), phenomenology and close to Immanuel Kant's transcendental idealism. Apart from this, he wrote several commentaries, works on logic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hetucakra
''Hetucakra'' or ''Wheel of Reasons'' is a Sanskrit text on logic written by Dignaga (c 480–540 CE). It concerns the application of his 'three modes’ (trairūpya), conditions or aspects of the middle term called ''hetu'' ("reason" for a conclusion) or ''linga'' ("mark", "sign" of a sound argument) in a valid inference within the Indian logico-epistemic tradition, sometimes referred to as Buddhist logic. Anacker's assessment Anacker (2005: p. 34), in introducing his English rendering of the "Method for Argumentation (Vāda-vidhi)" of Vasubandhu (fl. 4th century)—a text composed in Sanskrit which is now only extant in a reconstructed composite extracted from Tibetan works, collated by Frauwallner (1957)—holds that: Vasubandhu's criteria for a valid inference-schema are concise and precise, and there is nothing essential omitted. Dignāga's 'wheel of justifications' (''hetu-cakra''), sometimes held to be the first complete Indian formulation of what constitutes the v ...

History Of Logic
The history of logic deals with the study of the development of the science of valid inference (logic). Formal logics developed in ancient times in Indian logic, India, Logic in China, China, and Greek philosophy, Greece. Greek methods, particularly Aristotelian logic (or term logic) as found in the ''Organon'', found wide application and acceptance in Western science and mathematics for millennia.Boehner p. xiv The Stoicism, Stoics, especially Chrysippus, began the development of predicate logic. Christian philosophy, Christian and Logic in Islamic philosophy, Islamic philosophers such as Boethius (died 524), Avicenna (died 1037), Thomas Aquinas (died 1274) and William of Ockham (died 1347) further developed Aristotle's logic in the Medieval philosophy#High Middle Ages, Middle Ages, reaching a high point in the mid-fourteenth century, with Jean Buridan. The period between the fourteenth century and the beginning of the nineteenth century saw largely decline and neglect, and at le ...
