Gaṅgeśa
Gaṅgeśa ( sa, गंगेश उपाध्याय, ''Gaṅgeśa Upādhyāya'') (first half of the 14th century) was an Indian philosopher, logician and mathematician from the kingdom of Mithila. He established the Navya-Nyāya ("New Logic") school. His '' Tattvachintāmaṇi'' (The Jewel of Thought on the Nature of Things), also known as ''Pramāṇacintāmaṇi'' (The Jewel of Thought on the Means of Valid Knowledge), is the basic text for all later developments. The logicians of this school were primarily interested in defining their terms and concepts related to non-binary logical categories. Life Gangesa was born at Karion village on the banks of the Kamala River, 19 km south-east of Darbhanga in a Brahmin family. According to tradition, he was illiterate in his early years but later he acquired the knowledge of logic as a boon from the goddess Kali. There is a story that he was an idiot from birth, his in-laws always gave him bones of fish when eating. On ...

Tattvachintamani
Tattvachintamani is a treatise in Sanskrit authored by 14th-century CE Indian logician and philosopher Gangesa (fl. c. 1325). The title may be translated into English as "A Thought-jewel of Truth." The treatise is also known as Pramāṇa-chintāmaṇi ("A Thought-jewel of Valid Knowledge"). The treatise introduced a new era in the history of Indian logic. Satis Chandra Vidyabhusana in his authoritative 681-page history of Indian logic divided the millennia long history of Indian logic into three sometimes-overlapping periods: Ancient period (650 BCE100 CE), Medieval period (1001200 CE) and Modern period (from 900 CE). He also identified certain standard work as typical representative of each of these periods. Tattvachintamani of Gangesa is the text identified as the standard work of the Modern period in the history of Indian logic, the standard works for the earlier periods being Nyāya Sūtra by Akshapāda Gautama (Ancient period) and Pramāṇa-samuccaya by Dignāga Dign ...

Navya-Nyāya
The Navya-Nyāya or Neo-Logical ''darśana'' (view, system, or school) of Indian logic and Indian philosophy was founded in the 13th century CE by the philosopher Gangeśa Upādhyāya of Mithila and continued by Raghunatha Siromani of Nabadwipa in Bengal. It was a development of the classical Nyāya ''darśana''. Other influences on Navya-Nyāya were the work of earlier philosophers Vācaspati Miśra (900–980 CE) and Udayana (late 10th century). It remained active in India through to the 18th century. Gangeśa's book '' Tattvacintāmaṇi'' ("Thought-Jewel of Reality") was written partly in response to Śrīharśa's ''Khandanakhandakhādya'', a defence of Advaita Vedānta, which had offered a set of thorough criticisms of Nyāya theories of thought and language. In his book, Gangeśa both addressed some of those criticisms and – more important – critically examined the Nyāya ''darśana'' itself. He held that, while Śrīharśa had failed to successfully ...

Philosopher
A philosopher is a person who practices or investigates philosophy. The term ''philosopher'' comes from the grc, φιλόσοφος, , translit=philosophos, meaning 'lover of wisdom'. The coining of the term has been attributed to the Greek thinker Pythagoras (6th century BCE).. In the Classics, classical sense, a philosopher was someone who lived according to a certain way of life, focusing upon resolving Meaning of life, existential questions about the human condition; it was not necessary that they discoursed upon Theory, theories or commented upon authors. Those who most arduously committed themselves to this lifestyle would have been considered ''philosophers''. In a modern sense, a philosopher is an intellectual who contributes to one or more branches of philosophy, such as aesthetics, ethics, epistemology, philosophy of science, logic, metaphysics, social theory, philosophy of religion, and political philosophy. A philosopher may also be someone who has worked in the hum ...

People From Darbhanga District
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Scientists From Bihar
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Epistemologists
Epistemology (; ), or the theory of knowledge, is the branch of philosophy concerned with knowledge. Epistemology is considered a major subfield of philosophy, along with other major subfields such as ethics, logic, and metaphysics. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in epistemology are generally clustered around four core areas: # The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification # Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony # The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs # Philosophical skepticism, which questions the possibi ...

13th-century Indian Philosophers
The 13th century was the century which lasted from January 1, 1201 ( MCCI) through December 31, 1300 ( MCCC) in accordance with the Julian calendar. The Mongol Empire was founded by Genghis Khan, which stretched from Eastern Asia to Eastern Europe. The conquests of Hulagu Khan and other Mongol invasions changed the course of the Muslim world, most notably the Siege of Baghdad (1258), the destruction of the House of Wisdom and the weakening of the Mamluks and Rums which, according to historians, caused the decline of the Islamic Golden Age. Other Muslim powers such as the Mali Empire and Delhi Sultanate conquered large parts of West Africa and the Indian subcontinent, while Buddhism witnessed a decline through the conquest led by Bakhtiyar Khilji. The Southern Song dynasty would begin the century as a prosperous kingdom but would eventually be invaded and annexed into the Yuan dynasty of the Mongols. The Kamakura Shogunate of Japan would be invaded by the Mongols. Goryeo resiste ...
