Hindu philosophyHindu philosophy or Vedic philosophy is the set of Indian philosophical systems developing alongside the religion of Hinduism and emerging in the Iron and Classical periods, which consists of six orthodox schools of thought (shad-darśana): Samkhya, Yoga, Nyaya, Vaisheshika, Mimamsa and Vedanta. In Indian tradition, the word used for philosophy is Darshana (viewpoint or perspective), from the Sanskrit root drish ('to see, to experience'). These are also called the āstika philosophical traditions: those that accept the Vedas as an authoritative, important source of knowledge.
YajnavalkyaYajnavalkya or Yagyavalkya (याज्ञवल्क्य, ) is a Hindu Vedic sage figuring in the Brihadaranyaka Upanishad (c. 700 BCE). Yajnavalkya proposes and debates metaphysical questions about the nature of existence, consciousness and impermanence, and expounds the epistemic doctrine of neti neti ("not this, not this") to discover the universal Self and Ātman. Texts attributed to him include the Yajnavalkya Smriti, Yoga Yajnavalkya and some texts of the Vedanta school. He is also mentioned in various Brahmanas and Aranyakas.
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.
TranscendentalismTranscendentalism is a philosophical, spiritual, and literary movement that developed in the late 1820s and 1830s in the New England region of the United States. A core belief is in the inherent goodness of people and nature, and while society and its institutions have corrupted the purity of the individual, people are at their best when truly "self-reliant" and independent. Transcendentalists saw divine experience inherent in the everyday, rather than believing in a distant heaven.
CharvakaCharvaka (चार्वाक; IAST: Cārvāka), also known as Lokāyata, is an ancient school of Indian materialism. It is considered an example of atheistic schools in the Hindu tradition. Charvaka holds direct perception, empiricism, and conditional inference as proper sources of knowledge, embraces philosophical skepticism and rejects ritualism. It was a popular belief system in ancient India. Brihaspati, a philosopher, is traditionally referred to as the founder of Charvaka or Lokāyata philosophy, although some scholars dispute this.
Nyaya(Sanskrit: न्याय, nyā-yá), literally meaning "justice", "rules", "method" or "judgment", is one of the six traditional schools of Hindu philosophy that affirm the Vedas (an astika school). Nyaya's most significant contributions to Indian philosophy were 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).
ĀjīvikaAjivika (Sanskrit; IAST: ) is one of the nāstika or "heterodox" schools of Indian philosophy. Believed to be founded in the 5th century BCE by Makkhali Gosāla, it was a Śramaṇa movement and a major rival of Vedic religion, early Buddhism, and Jainism. Ājīvikas were organized renunciates who formed discrete communities. The precise identity of the Ājīvikas is not well known, and it is even unclear if they were a divergent sect of the Buddhists or the Jains.
SamkhyaSamkhya or Sankya (ˈsɑːŋkjə; sāṃkhya) is a dualistic orthodox school of Hindu philosophy. It views reality as composed of two independent principles, Puruṣa ('consciousness' or spirit) and Prakṛti (nature or matter, including the human mind and emotions). Puruṣa is the witness-consciousness. It is absolute, independent, free, beyond perception, above any experience by mind or senses, and impossible to describe in words. Unmanifest Prakriti is matter or nature.
Sarvepalli RadhakrishnanSarvepalli Radhakrishnan (; 5 September 1888 - 17 April 1975; natively Radhakrishnayya) was an Indian politician, philosopher, and statesman who served as the second president of India from 1962 to 1967. He previously served as the first vice president of India from 1952 to 1962. He was the second ambassador of India to the Soviet Union from 1949 to 1952. He was also the fourth vice-chancellor of Banaras Hindu University from 1939 to 1948 and the second vice-chancellor of Andhra University from 1931 to 1936.
Substance theorySubstance theory, or substance–attribute theory, is an ontological theory positing that objects are constituted each by a substance and properties borne by the substance but distinct from it. In this role, a substance can be referred to as a substratum or a thing-in-itself. Substances are particulars that are ontologically independent: they are able to exist all by themselves. Another defining feature often attributed to substances is their ability to undergo changes. Changes involve something existing before, during and after the change.
