VasubandhuVasubandhu (Sanskrit: वसुबन्धु; ; Tibetan: དབྱིག་གཉེན་ ; fl. 4th to 5th century CE) was an influential Buddhist monk and scholar from Gandhara. He was a philosopher who wrote commentary on the Abhidharma, from the perspectives of the Sarvastivada and Sautrāntika schools. After his conversion to Mahayana Buddhism, along with his half-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.
ChandrakirtiChandrakirti (; ; 600-650, meaning "glory of the moon" in Sanskrit) or "Chandra" was a Buddhist scholar of the Madhyamaka school and a noted commentator on the works of Nagarjuna (150-250 CE) and those of his main disciple, Aryadeva. He wrote two influential works on madhyamaka, the Prasannapadā and the Madhyamakāvatāra. Chandrakirti does not seem to have been very influential during the 7th to 10 centuries, and his works were never translated into Chinese.
Philosophical skepticismPhilosophical skepticism (UK spelling: scepticism; from Greek σκέψις skepsis, "inquiry") is a family of philosophical views that question the possibility of knowledge. It differs from other forms of skepticism in that it even rejects very plausible knowledge claims that belong to basic common sense. Philosophical skeptics are often classified into two general categories: Those who deny all possibility of knowledge, and those who advocate for the suspension of judgment due to the inadequacy of evidence.
PramanavarttikaThe Pramāṇavārttika (Brahmi: 𑀧𑁆𑀭𑀫𑀸𑀡𑀯𑀸𑀭𑁆𑀢𑁆𑀢𑀺𑀓, Commentary on Valid Cognition; Tib. tshad ma rnam 'grel) is an influential Buddhist text on pramana (valid instruments of knowledge, epistemic criteria), a form of Indian epistemology. The Pramāṇavārttika is the magnum opus of the Indian Buddhist Dharmakirti (floruit 6-7th centuries). The Pramanavarttika is written in about 2,000 verse stanzas. The four chapters deal, respectively, with inference for oneself (svarthanumana), valid knowledge (pramanasiddhi), sense perception (pratyaksa), and inference for others (pararthanumana).
Buddhist philosophyBuddhist philosophy is the ancient Indian philosophical system that developed within the religio-philosophical tradition of Buddhism. It comprises all the philosophical investigations and systems of rational inquiry that developed among various schools of Buddhism in ancient India following the parinirvāṇa of Gautama Buddha (c. 5th century BCE), as well as the further developments which followed the spread of Buddhism throughout Asia. Buddhism combines both philosophical reasoning and the practice of meditation.
UdayanaUdayana, (Devanagari: उदयन) also known as Udayanācārya (Udyanacharya, or Master Udayana), (circa 975 - 1050 CE) was an Indian philosopher and logician of the tenth century of the Nyaya school who attempted to devise a rational theology to prove the existence of God using logic and counter the attack on the existence of God at the hands of Buddhist philosophers such as Dharmakīrti, Jñānaśrī and against the Indian school of materialism (Chārvaka). He is considered to be the most important philosopher of the Nyāya tradition.
Buddhist atomismBuddhist atomism is a school of atomistic Buddhist philosophy that flourished on the Indian subcontinent during two major periods. During the first phase, which began to develop prior to the 6th century CE, Buddhist atomism had a very qualitative, Aristotelian-style atomic theory. This form of atomism identifies four kinds of atoms, corresponding to the standard elements. Each of these elements has a specific property, such as solidity or motion, and performs a specific function in mixtures, such as providing support or causing growth.
BhartṛhariBhartṛhari (Devanagari: भर्तृहरि; also romanised as Bhartrihari; fl. c. 5th century CE) was a Hindu linguistic philosopher to whom are normally ascribed two influential Sanskrit texts: the Trikāṇḍī (including Vākyapadīya), on Sanskrit grammar and linguistic philosophy, a foundational text in the Indian grammatical tradition, explaining numerous theories on the word and on the sentence, including theories which came to be known under the name of Sphoṭa; in this work Bhartrhari also discussed logical problems such as the liar paradox and a paradox of unnameability or unsignifiability which has become known as Bhartrhari's paradox, and the Śatakatraya, a work of Sanskrit poetry, comprising three collections of about 100 stanzas each; it may or may not be by the same author who composed the two mentioned grammatical works.
RatnakīrtiRatnakīrti (11th century CE) was an Indian Buddhist philosopher of the Yogācāra and epistemological (pramāṇavāda) schools who wrote on logic, philosophy of mind and epistemology. Ratnakīrti studied at the Vikramaśīla monastery in modern-day Bihar. He was a pupil of Jñānaśrīmitra, and Ratnakīrti refers to Jñānaśrīmitra in his work as his guru with phrases such as yad āhur guravaḥ. Ratnakīrti's work has been termed as "more concise and logical though not so poetical" compared to that of his teacher, although he does build on much of Jñānaśrīmitra's work.
Buddhism and scienceThe relationship between Buddhism and science is a subject of contemporary discussion and debate among Buddhists, scientists and scholars of Buddhism. Historically, Buddhism encompasses many types of beliefs, traditions and practices, so it is difficult to assert any single "Buddhism" in relation to science. Similarly, the issue of what "science" refers to remains a subject of debate, and there is no single view on this issue.
