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. 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 challenge the Nyāya realist ontology, his and Gangeśa's own criticisms brought out a need to improve and refine the logical and linguistic tools of Nyāya thought, to make them more rigorous and precise.
Tattvacintāmani dealt with all the important aspects of Indian philosophy, logic, set theory, and especially epistemology, which Gangeśa examined rigorously, developing and improving the Nyāya scheme, and offering examples. The results, especially his analysis of cognition, were taken up and used by other darśanas.
Navya-Nyāya developed a sophisticated language and conceptual scheme that allowed it to raise, analyse, and solve problems in logic and epistemology. It systematised all the Nyāya concepts into four main categories (sense-)perception (pratyakşa), inference (anumāna), comparison or similarity (upamāna), and testimony (sound or word; śabda). Prof John Vattanky has contributed significantly to the modern understanding of Navya-Nyāya.

Philosophical cosmology, philosophy of cosmology or philosophy of cosmos is a discipline directed to the philosophical contemplation of the universe as a totality, and to its conceptual foundations. It draws on several branches of philosophy—metaphysics, epistemology, philosophy of physics, philosophy of science, philosophy of mathematics, and on the fundamental theories of physics. The term cosmology was used at least as early as 1730, by German philosopher Christian Wolff, in Cosmologia Generalis.Daniel H. H. Ingalls Sr.
Daniel Henry Holmes Ingalls Sr. (May 4, 1916 – July 17, 1999) was the Wales Professor of Sanskrit at Harvard University.Danish philosophy
Danish philosophy has a long tradition as part of Western philosophy.
Perhaps the most influential Danish philosopher was Søren Kierkegaard, the creator of Christian existentialism, which inspired the philosophical movement of Existentialism. Kierkegaard had a few Danish followers, including Harald Høffding, who later in his life moved on to join the movement of positivism. Among Kierkegaard's other followers include Jean-Paul Sartre who was impressed with Kierkegaard's views on the individual, and Rollo May, who helped create humanistic psychology.Early modern philosophy
Early modern philosophy (also classical modern philosophy) is a period in the history of philosophy at the beginning or overlapping with the period known as modern philosophy.Ethnophilosophy
Ethnophilosophy is the study of indigenous philosophical systems. The implicit concept is that a specific culture can have a philosophy that is not applicable and accessible to all peoples and cultures in the world; however, this concept is disputed by traditional philosophers. An example of ethnophilosophy is African philosophy.Gangesha Upadhyaya
Gangesha Upadhyaya (Sanskrit: गंगेश उपाध्याय, Gaṅgeśa Upādhyāya) (late 12th century) was an Indian mathematician and philosopher from the kingdom of Mithila. He established the Navya-Nyāya ("New Logic") school. His Tattvacintāmaṇi (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.Harvard Oriental Series
The Harvard Oriental Series is a book series founded in 1891 by Charles Rockwell Lanman and Henry Clarke Warren. Lanman served as its inaugural editor (1891-1934) for the first 37 volumes. Other editors of the series include Walter Eugene Clark (1934-1950, volumes 38-44), Daniel Henry Holmes Ingalls (1950-1983, volumes 45-48) and Gary Tubb (1983-1990, volume 49).
Currently in its 73rd volume, the series is edited by Michael Witzel, the Wales Professor of Sanskrit in the Department of Sanskrit and Indian Studies at Harvard University, and distributed by the Harvard University Press.Indian logic
The development of Indian logic dates back to the anviksiki of Medhatithi Gautama (c. 6th century BCE); the Sanskrit grammar rules of Pāṇini (c. 5th century BCE); the Vaisheshika school's analysis of atomism (c. 6th century BCE to 2nd century BCE); the analysis of inference by Gotama (c. 6th century BC to 2nd century CE), founder of the Nyaya school of Hindu philosophy; and the tetralemma of Nagarjuna (c. 2nd century CE).
Indian logic stands as one of the three original traditions of logic, alongside the Greek and the Chinese logic. The Indian tradition continued to develop through early to modern times, in the form of the Navya-Nyāya school of logic.List of teachers of Nyaya

Navya weekly, Telugu weekly magazine
Navya-Nyāya, view, system, or school of Indian logic and philosophy, founded in the 13th century

Nyāya (Sanskrit: न्याय, nyā-yá), literally means "rules", "method" or "judgment". It is also the name of one of the six orthodox (astika) schools of Hinduism. This school's most significant contributions to Indian philosophy was systematic development of the theory of logic, methodology, and its treatises on epistemology.Nyaya school's epistemology accepts four out of six Pramanas as reliable means of gaining knowledge – Pratyakṣa (perception), Anumāṇa (inference), Upamāṇa (comparison and analogy) and Śabda (word, testimony of past or present reliable experts). In its metaphysics, Nyaya school is closer to Vaisheshika school of Hinduism than others. It holds that human suffering results from mistakes/defects produced by activity under wrong knowledge (notions and ignorance). Moksha (liberation), it states, is gained through right knowledge. This premise led Nyaya to concern itself with epistemology, that is the reliable means to gain correct knowledge and to remove wrong notions. False knowledge is not merely ignorance to Naiyyayikas, it includes delusion. Correct knowledge is discovering and overcoming one's delusions, and understanding true nature of soul, self and reality.Naiyyayika scholars approached philosophy as a form of direct realism, stating that anything that really exists is in principle humanly knowable. To them, correct knowledge and understanding is different from simple, reflexive cognition; it requires Anuvyavasaya (अनुव्यवसाय, cross-examination of cognition, reflective cognition of what one thinks one knows). An influential collection of texts on logic and reason is the Nyayasutras, attributed to Aksapada Gautama, variously estimated to have been composed between 6th-century BCE and 2nd-century CE.Nyaya school shares some of its methodology and human suffering foundations with Buddhism; however, a key difference between the two is that Buddhism believes that there is neither a soul nor self; Nyaya school like other schools of Hinduism believes that there is a soul and self, with liberation (moksha) as a state of removal of ignorance, wrong knowledge, the gain of correct knowledge and unimpeded continuation of self.Padārtha
Padārtha is a Sanskrit word for "categories" in Vaisheshika and Nyaya schools of Hindu philosophy.Philosophy of film
The philosophy of film is a branch of aesthetics within the discipline of philosophy that seeks to understand the most basic questions regarding film. Philosophy of film has significant overlap with film theory, a branch of film studies.Prashastapada
Praśastapāda (Sanskrit: प्रशस्तपाद) was an ancient Indian philosopher. He wrote the Padārtha-dharma-saṅgraha (Collection of Properties of Matter) and a commentary, titled Praśastapāda Bhāṣya , on the Vaisheshika Sutras of Kanada (Circa 6th Century BCE), both texts are comprehensive books in physics. In these texts Prashastapada discusses the properties of motion. Ganganath Jha had translated Praśastapāda Bhāṣya which translation was published in 1916. Prashasta or Praśasta (Sanskrit: प्रशस्त) means praised or praiseworthy, lauded or laudable, commended or commendable or eulogized.Dayananda Saraswati writes that the Sutras of Kanāda and Padārthadharmasaṅgraha of Praśastapāda do not show much influence of the Nyaya System. Praśastapāda Bhāṣya is actually not a commentary but an independent compendium of the tenets of the Vaisheshika School. Udayanacharya of the Navya-Nyāya School, the author of Lakṣaṇāvalī which gives the definitions of Vaiśeṣika terms, and Nyāya Kusumanjali which is a systematic account of Nyaya Theism, who also belonged to Mithila, had written Kiranavali which is a commentary on Praśastapāda Bhāṣya .Praśastapāda can be tentatively dated to the second half of the 6th century C.E. The Vaiśeṣika philosophy recognizes twenty-four gunas or qualities that are inherent in substances; these include seventeen gunas listed by Kanada and seven gunas – gurutva (heaviness), dravatva (fluidity), sneha (viscidity), dharma (merit), adharma (demerit), shabda (sound) and samskara (faculty) - added by Praśastapāda. Vyomavati of Vyomaśekhara, Nyayakandali of Shridhara, Kiranavali of Udayana and Lilavati of Śrīvatsa are well known commentaries on his works.Praśastapāda refers to a type of perception that is the simple intuition ( alochana ) of the proper form ( svarupa ) of an entity, which is the apprehension of an undifferentiated ( avibhktam ) whole arising from cognition of its specific universals. This is the preliminary stage. He differs from Dignāga for whom the determinates of cognitions are subjective constructs imposed upon the given, and constructive cognition is not a perception; Praśastapāda, who was a realist, avers that the determinates are objective constituents of reality and their conceptual co-relates are not inter-subjective fictions. Praśastapāda by redefining substance as per se a possessor of attributes opened new turf by separating the cosmological from the logical dimensions of concepts. His commentary overshadowed the Vaisheshika Sutras and became the main vehicle for later commentaries. Praśastapāda describes the dissolution of the earth, water, air and fire in terms of their atomic constituents but excludes space because space is non-atomic. With regard to the conjoining and disjoining of atoms he includes a higher will or order as the guiding principle of universal dissolution which over-rides the natural karma of atoms.Kaṇāda does not directly refer to Ishvara (God) but Praśastapāda sees Ishvara as the cause of the universe but does not explain how God creates.Raghunatha Siromani
Raghunatha Shiromani (Bengali: রঘুনাথ শিরোমণি, IAST: Raghunātha Śiromaṇi) (c. 1477–1547) was an Indian philosopher and logician. He was born at Nabadwip in present-day Nadia district of West Bengal state. He was the grandson of Śulapāṇi (c. 14th century CE), a noted writer on Smṛti from his mother's side. He was a pupil of Vāsudeva Sārvabhauma. He brought the new school of Nyaya, Navya Nyāya, representing the final development of Indian formal logic, to its zenith of analytic power.
Raghunatha's analysis of relations revealed the true nature of number, inseparable from the abstraction of natural phenomena, and his studies of metaphysics dealt with the negation or nonexistence of a complex reality. His most famous work in logic was the Tattvacintāmaṇidīdhiti, a commentary on the Tattvacintāmaṇi of Gangeśa Upādhyāya, founder of the Navya Nyāya school.
A descriptive information of Raghunatha with some controversial issues (his connection with Mahaprabhu Shri Chaitanya) and bibliography are to be found at

Turkish philosophy has long been affected by Islam and the country's proximity to Greece and ancient Greek philosophy.Udayana
Udayana, also known as Udayanācārya (Udyanacharya, or Master Udayana), was a very important Hindu logician of the tenth century who attempted to reconcile the views held by the two major schools of logic (Nyaya and Vaisheshika). This became the root of the Navya-Nyāya school of the thirteenth century, established by the Gangesha Upadhyaya ("New Nyāya") school of "right" reasoning, which is still recognized and followed in some regions of India. He lived in Kariyan village in Mithila, near present-day Darbhanga, Bihar state, India.
Udayana wrote a sub-gloss on Vachaspati's work called the Nyaya-vaartika-taatparya-tiikaa-parishuddhi. He wrote several other works such as the Kusumanjali, Atma-tattva-viveka, Kiranaavali and Nyaya-parishishhta (also called Bodha siddhi or Bodha shuddhi).
He is given credit by Naiyâyikas for having demolished in a final fashion the claims of the Buddhist logicians. All his works, or at least all of which we know, have been preserved, which attest to the respect in which he was held from the beginning.
