Indian philosophy

Indian philosophy refers to philosophical traditions of the Indian subcontinent. A traditional Hindu classification divides āstika and nāstika schools of philosophy, depending on one of three alternate criteria: whether it believes the Vedas as a valid source of knowledge; whether the school believes in the premises of Brahman and Atman; and whether the school believes in afterlife and Devas.^[2][3][4]

Indian philosophical traditions

Yajnavalkya (c. 8th century BCE), an important Vedic sage associated with the thought of the early Upanishads.^[1] Jain philosophy was propagated by Tirthankaras, notably Parshvanatha (c. 872 – c. 772 BCE) and Mahavira (c. 549–477 BCE). Buddhist philosophy was founded by Gautama Buddha (c. 563–483 BCE). Sikh philosophy was developed by Guru Gobind Singh (c. 1666–1708 CE).

There are six major (āstika) schools of Vedic philosophy—Nyaya, Vaisheshika, Samkhya, Yoga, Mīmāṃsā and Vedanta—and five major heterodox (nāstika or sramanic) schools—Jain, Buddhist, Ajivika, Ajñana, and Charvaka. The āstika group embraces the Vedas as an essential source of its foundations, while the nāstika group does not. However, there are other methods of classification; Vidyaranya for instance identifies sixteen schools of Indian philosophy by including those that belong to the Śaiva and Raseśvara traditions.^[5][6]

The main schools of Indian philosophy were formalised and recognised chiefly between 500 BCE and the late centuries of the Common Era.^{[citation needed]} Competition and integration between the various schools was intense, despite later claims of Hindu unity. Some schools like Jainism, Buddhism, Yoga, Śaiva and Vedanta survived, but others, like Ajñana, Charvaka and Ājīvika did not.

Ancient and medieval era texts of Indian philosophies include extensive discussions on ontology (metaphysics, Brahman-Atman, Sunyata-Anatta), reliable means of knowledge (epistemology, Pramanas), value system (axiology) and other topics.^{[7][page needed][8][9][10]}

Common themes

Indian philosophies share many concepts such as dharma, karma, samsara, dukkha, renunciation, meditation, with almost all of them focusing on the ultimate goal of liberation of the individual from dukkha and samsara through diverse range of spiritual practices (moksha, nirvana).^[11] They differ in their assumptions about the nature of existence as well as the specifics of the path to the ultimate liberation, resulting in numerous schools that disagreed with each other. Their ancient doctrines span the diverse range of philosophies found in other ancient cultures.^[12]

Orthodox schools

Main articles: Hindu philosophy, Hinduism, Vedas, and Upanishads

 

Hindu philosophy has a diversity of traditions and numerous saints and scholars, such as Adi Shankara of Advaita Vedanta school.

Some of the earliest surviving Indian philosophical texts are the Upanishads of the later Vedic period (1000–500 BCE), which are considered to preserve the ideas of Brahmanism. Indian philosophical traditions are commonly grouped according to their relationship to the Vedas and the ideas contained in them. Jainism and Buddhism originated at the end of the Vedic period, while the various traditions grouped under Hinduism mostly emerged after the Vedic period as independent traditions. Hindus generally classify Indian philosophical traditions as either orthodox (āstika) or heterodox (nāstika) depending on whether they accept the authority of the Vedas and the theories of brahman and ātman found therein.^[2][3]

The schools which align themselves with the thought of the Upanishads, the so-called "orthodox" or "Hindu" traditions, are often classified into six darśanas or philosophies:Sānkhya, Yoga, Nyāya, Vaisheshika, Mimāmsā and Vedānta.^[13]

The doctrines of the Vedas and Upanishads were interpreted differently by these six schools of Hindu philosophy, with varying degrees of overlap. They represent a "collection of philosophical views that share a textual connection", according to Chadha 2015.^[14] They also reflect a tolerance for a diversity of philosophical interpretations within Hinduism while sharing the same foundation.^[15]

Hindu philosophers of the six orthodox schools developed systems of epistemology (pramana) and investigated topics such as metaphysics, ethics, psychology (guṇa), hermeneutics, and soteriology within the framework of the Vedic knowledge, while presenting a diverse collection of interpretations.^{[16][17][18][19]} The commonly named six orthodox schools were the competing philosophical traditions of what has been called the "Hindu synthesis" of classical Hinduism.^[20][21][22]

These "Six Philosophies" (ṣaḍ-darśana) are:

• Sāṃkhya, a philosophical tradition which regards the universe as consisting of two independent realities: puruṣa (the perceiving consciousness) and prakṛti (perceived reality, including mind, perception, kleshas, and matter) and which describes a soteriology based on this duality, in which purush is discerned and disentangled from the impurities of prakriti. It has included atheistic authors as well as some theistic thinkers, and forms the basis of much of subsequent Indian philosophy.
• Yoga, a school similar to Sāṃkhya (or perhaps even a branch of it) which accepts a personal god and focuses on yogic practice.
• Nyāya, a philosophy which focuses on logic and epistemology. It accepts six kinds of pramanas (epistemic warrants): (1) perception, (2) inference, (3) comparison and analogy, (4) postulation, derivation from circumstances, (5) non-perception, negative/cognitive proof and (6) word, testimony of past or present reliable experts. Nyāya defends a form of direct realism and a theory of substances (dravya).
• Vaiśeṣika, closely related to the Nyāya school, this tradition focused on the metaphysics of substance, and on defending a theory of atoms. Unlike Nyāya, they only accept two pramanas: perception and inference.
• Pūrva-Mīmāṃsā, a school which focuses on exegesis of the Vedas, philology and the interpretation of Vedic ritual.
• Vedānta (also called Uttara Mīmāṃsā), focuses on interpreting the philosophy of the Upanishads, particularly the soteriological and metaphysical ideas relating to Atman and Brahman.

Sometimes these groups are often coupled into three groups for both historical and conceptual reasons: Nyāya-Vaiśeṣika, Sāṃkhya-Yoga, and Mīmāṃsā-Vedānta.

Each tradition included different currents and sub-schools, for example, Vedānta was divided among the sub-schools of Advaita (non-dualism), Visishtadvaita (qualified non-dualism), Dvaita (dualism), Dvaitadvaita (dualistic non-dualism), Suddhadvaita, and Achintya Bheda Abheda (inconceivable oneness and difference).

Besides these schools Mādhava Vidyāraṇya also includes the following of the aforementioned theistic philosophies based on the Agamas and Tantras:^[5]

• Pasupata, school of Shaivism by Nakulisa
• Saiva, the theistic Sankhya school
• Pratyabhijña, the recognitive school
• Raseśvara, the mercurial school
• Pāṇini Darśana, the grammarian school (which clarifies the theory of Sphoṭa)

The systems mentioned here are not the only orthodox systems, they are the chief ones, and there are other orthodox schools. These systems, accept the authority of Vedas and are regarded as orthodox (astika) schools of Hindu philosophy; besides these, schools that do not accept the authority of the Vedas are heterodox (nastika) systems such as Buddhism, Jainism, Ajivika and Charvaka.^[23][24][25] This orthodox-heterodox terminology is a construct of Western languages, and lacks scholarly roots in Sanskrit. According to Andrew Nicholson, there have been various heresiological translations of Āstika and Nāstika in 20th century literature on Indian philosophies, but quite many are unsophisticated and flawed.^[4]

• Charvaka is a materialistic and atheistic school of thought and, is noteworthy as evidence of a materialistic movement within Hinduism.^[26]

Heterodox (Śramaṇic schools)

Main article: Śramaṇa

Several Śramaṇic movements have existed before the 6th century BCE, and these influenced both the āstika and nāstika traditions of Indian philosophy.^[27] The Śramaṇa movement gave rise to diverse range of heterodox beliefs, ranging from accepting or denying the concept of soul, atomism, antinomian ethics, materialism, atheism, agnosticism, fatalism to free will, idealization of extreme asceticism to that of family life, strict ahimsa (non-violence) and vegetarianism to permissibility of violence and meat-eating.^[28] Notable philosophies that arose from Śramaṇic movement were Jainism, early Buddhism, Charvaka, Ajñana and Ājīvika.^[29]

Ajñana philosophy

Main article: Ajñana

Ajñana was one of the nāstika or "heterodox" schools of ancient Indian philosophy, and the ancient school of radical Indian skepticism. It was a Śramaṇa movement and a major rival of early Buddhism and Jainism. They have been recorded in Buddhist and Jain texts. They held that it was impossible to obtain knowledge of metaphysical nature or ascertain the truth value of philosophical propositions; and even if knowledge was possible, it was useless and disadvantageous for final salvation. They were sophists who specialised in refutation without propagating any positive doctrine of their own.

Jain philosophy

Main articles: Jain philosophy and Jainism

 

Rishabhanatha, believed to have lived over a million years ago, is considered the founder of Jain religion in the present time cycle.

Jain philosophy is the oldest Indian philosophy that separates body (matter) from the soul (consciousness) completely.^[30] Jainism was revived and re-established after Mahavira, the last and the 24th Tirthankara, synthesised and revived the philosophies and promulgations of the ancient Śramaṇic traditions laid down by the first Jain tirthankara Rishabhanatha millions of years ago.^[31] According to Dundas, outside of the Jain tradition, historians date the Mahavira as about contemporaneous with the Buddha in the 5th-century BCE, and accordingly the historical Parshvanatha, based on the c. 250-year gap, is placed in 8th or 7th century BCE.^[32]

Jainism is a Śramaṇic religion and rejected the authority of the Vedas. However, like all Indian religions, it shares the core concepts such as karma, ethical living, rebirth, samsara and moksha. Jainism places strong emphasis on asceticism, ahimsa (non-violence) and anekantavada (relativity of viewpoints) as a means of spiritual liberation, ideas that influenced other Indian traditions.^[33] Jainism strongly upholds the individualistic nature of soul and personal responsibility for one's decisions; and that self-reliance and individual efforts alone are responsible for one's liberation. According to the Jain philosophy, the world (Saṃsāra) is full of hiṃsā (violence). Therefore, one should direct all his efforts in attainment of Ratnatraya, that are Samyak Darshan (right perception), Samyak Gnana (right knowledge) and Samyak Chàritra (right conduct) which are the key requisites to attain liberation.^[34]

Buddhist philosophy

Main articles: Buddhist philosophy and Early Buddhist schools

 

The Buddhist philosophy is based on the teachings of the Buddha.

Buddhist philosophy is a system of thought which started with the teachings of Siddhartha Gautama, the Buddha, or "awakened one". Buddhism is founded on elements of the Śramaṇa movement, which flowered in the first half of the 1st millennium BCE, but its foundations contain novel ideas not found or accepted by other Sramana movements. Buddhism and Hinduism mutually influenced each other and shared many concepts, states Paul Williams, however it is now difficult to identify and describe these influences.^[35] Buddhism rejected the Vedic concepts of Brahman (ultimate reality) and Atman (soul, self) at the foundation of Hindu philosophies.^{[36][37][38][39]}

Buddhism shares many philosophical views with other Indian systems, such as belief in karma – a cause-and-effect relationship, samsara – ideas about cyclic afterlife and rebirth, dharma – ideas about ethics, duties and values, impermanence of all material things and of body, and possibility of spiritual liberation (nirvana or moksha).^[40][41] A major departure from Hindu and Jain philosophy is the Buddhist rejection of an eternal soul (atman) in favour of anatta (non-Self).^{[37][42][43][44][45]} After the death of the Buddha, several competing philosophical systems termed Abhidharma began to emerge as ways to systematize Buddhist philosophy.^[46] The Mahayana movement also arose (c. 1st century BCE onwards) and included new ideas and scriptures.

The main traditions of Buddhist philosophy in India (from 300 BCE to 1000 CE) were:^[47]

• The Mahāsāṃghika ("Great Community") tradition (which included numerous sub-schools, all are now extinct)
• The schools of the Sthavira ("Elders") tradition:
  • Vaibhāṣika ("Commentators") also known as the Sarvāstivāda-Vaibhāśika, was an Abhidharma tradition that composed the "Great Commentary" (Mahāvibhāṣa). They were known for their defense of the doctrine of "sarvāstitva" (all exists), which is a form of eternalism regarding the philosophy of time. They also supported direct realism and a theory of substances (svabhāva).
  • Sautrāntika ("Those who uphold the sutras"), a tradition which did not see the Abhidharma as authoritative, and instead focused on the Buddhist sutras. They disagreed with the Vaibhāṣika on several key points, including their eternalistic theory of time.
  • Pudgalavāda ("Personalists"), which were known for their controversial theory of the "person" (pudgala), now extinct.
  • Vibhajyavāda ("The Analysts"), a widespread tradition which reached Kashmir, South India and Sri Lanka. A part of this school has survived into the modern era as the Theravada tradition. Their orthodox positions can be found in the Kathavatthu. They rejected the views of the Pudgalavāda and of the Vaibhāṣika among others.
• The schools of the Mahāyāna ("Great Vehicle") tradition (which continue to influence Tibetan and East Asian Buddhism)
  • Madhyamaka ("Middle way" or "Centrism") founded by Nagarjuna. Also known as Śūnyavāda (the emptiness doctrine) and Niḥsvabhāvavāda (the no svabhāva doctrine), this tradition focuses on the idea that all phenomena are empty of any essence or substance (svabhāva).
  • Yogācāra ("Yoga praxis"), an idealistic school which held that only consciousness exists, and thus was also known as Vijñānavāda (the doctrine of consciousness).
  • Some scholars see the Tathāgatagarbha (or "Buddha womb/source") texts as constituting a third "school" of Indian Mahāyāna.^[48]
  • Vajrayāna (also known as Mantrayāna, Tantrayāna, Secret Mantra, and Tantric Buddhism) is often placed in a separate category due to its unique tantric elements.
• The Dignāga-Dharmakīrti tradition is an influential school of thought which focused on epistemology, or pramāṇa ('means of knowledge').

Many of these philosophies were brought to other regions, like Central Asia and China. After the disappearance of Buddhism from India, some of these philosophical traditions continued to develop in the Tibetan Buddhist, East Asian Buddhist and Theravada Buddhist traditions.^[49][50]

Ājīvika philosophy

Main article: Ājīvika

The philosophy of Ājīvika was founded by Makkhali Gosala, it was a Śramaṇa movement and a major rival of early Buddhism and Jainism.^[52] Ājīvikas were organised renunciates who formed discrete monastic communities prone to an ascetic and simple lifestyle.^[53]

Original scriptures of the Ājīvika school of philosophy may once have existed, but these are currently unavailable and probably lost. Their theories are extracted from mentions of Ajivikas in the secondary sources of ancient Indian literature, particularly those of Jainism and Buddhism which polemically criticized the Ajivikas.^[54] The Ājīvika school is known for its Niyati doctrine of absolute determinism (fate), the premise that there is no free will, that everything that has happened, is happening and will happen is entirely preordained and a function of cosmic principles.^[54][55] Ājīvika considered the karma doctrine as a fallacy.^[56] Ājīvikas were atheists^[57] and rejected the authority of the Vedas, but they believed that in every living being is an ātman – a central premise of Hinduism and Jainism.^[58][59]

Charvaka philosophy

Main article: Charvaka

Charvaka (Sanskrit: चार्वाक; IAST: Cārvāka), also known as Lokāyata, is an ancient school of Indian materialism.^[60] Charvaka holds direct perception, empiricism, and conditional inference as proper sources of knowledge, embraces philosophical skepticism and rejects ritualism and supernaturalism.^{[61][62][63][64][65]} It was a popular belief system in ancient India.^[a]

The etymology of Charvaka (Sanskrit: चार्वाक) is uncertain. Bhattacharya quotes the grammarian Hemacandra, to the effect that the word cārvāka is derived from the root carv, 'to chew' : "A Cārvāka chews the self (carvatyātmānaṃ cārvākaḥ). Hemacandra refers to his own grammatical work, Uṇādisūtra 37, which runs as follows: mavāka-śyāmāka-vārtāka-jyontāka-gūvāka-bhadrākādayaḥ. Each of these words ends with the āka suffix and is formed irregularly". This may also allude to the philosophy's hedonistic precepts of "eat, drink, and be merry".

Brihaspati is traditionally referred to as the founder of Charvaka or Lokāyata philosophy, although some scholars dispute this.^[67][68] During the Hindu reformation period in the first millennium BCE, when Buddhism was established by Gautama Buddha and Jainism was re-organized by Parshvanatha, the Charvaka philosophy was well documented and opposed by both religions.^[69] Much of the primary literature of Charvaka, the Barhaspatya sutras, were lost either due to waning popularity or other unknown reasons.^[70] Its teachings have been compiled from historic secondary literature such as those found in the shastras, sutras, and the Indian epic poetry as well as in the dialogues of Gautama Buddha and from Jain literature.^[70][71] However, there is text that may belong to the Charvaka tradition, written by the skeptic philosopher Jayarāśi Bhaṭṭa, known as the Tattvôpaplava-siṁha, that provides information about this school, albeit unorthodox.^[72][73]

One of the widely studied principles of Charvaka philosophy was its rejection of inference as a means to establish valid, universal knowledge, and metaphysical truths.^[74][75] In other words, the Charvaka epistemology states that whenever one infers a truth from a set of observations or truths, one must acknowledge doubt; inferred knowledge is conditional.^[76]

Comparison of Indian philosophies

The Indian traditions subscribed to diverse philosophies, significantly disagreeing with each other as well as orthodox Indian philosophy and its six schools of Hindu philosophy. The differences ranged from a belief that every individual has a soul (self, atman) to asserting that there is no soul,^{[37][42][43][44][77]} from axiological merit in a frugal ascetic life to that of a hedonistic life, from a belief in rebirth to asserting that there is no rebirth.^[78]

Political philosophy

The Arthashastra, attributed to the Mauryan minister Chanakya, is one of the early Indian texts devoted to political philosophy. It is dated to 4th century BCE and discusses ideas of statecraft and economic policy.

The political philosophy most closely associated with modern India is the one of ahimsa (non-violence) and Satyagraha, popularised by Mahatma Gandhi during the Indian struggle for independence. In turn it influenced the later independence and Civil Rights movements, especially those led by Martin Luther King Jr. and Nelson Mandela. Prabhat Ranjan Sarkar's Progressive Utilization Theory^[122] is also a major socio-economic and political philosophy.^[123]

Integral humanism was a set of concepts drafted by Upadhyaya as political program and adopted in 1965 as the official doctrine of the Jan Sangh.

Upadhyaya considered that it was of utmost importance for India to develop an indigenous economic model with a human being at center stage. This approach made this concept different from Socialism and Capitalism. Integral Humanism was adopted as Jan Sangh's political doctrine and its new openness to other opposition forces made it possible for the Hindu nationalist movement to have an alliance in the early 1970s with the prominent Gandhian Sarvodaya movement going on under the leadership of J. P. Narayan. This was considered to be the first major public breakthrough for the Hindu nationalist movement.

Influence

In appreciation of complexity of the Indian philosophy, T. S. Eliot wrote that the great philosophers of India "make most of the great European philosophers look like schoolboys".^[124][125] Arthur Schopenhauer used Indian philosophy to improve upon Kantian thought. In the preface to his book The World As Will And Representation, Schopenhauer writes that one who "has also received and assimilated the sacred primitive Indian wisdom, then he is the best of all prepared to hear what I have to say to him."^[126] The 19th-century American philosophical movement Transcendentalism was also influenced by Indian thought.^[127][128]

ISBN 978-0-7914-2217-5. Central to Buddhist soteriology is the doctrine of not-self (Pali: anattā, Sanskrit: anātman, the opposed doctrine of ātman is central to Brahmanical thought). Put very briefly, this is the [Buddhist] doctrine that human beings have no soul, no self, no unchanging essence

In this chapter, we looked at religious metaphysics and saw two different ways of understanding Ultimate Reality. On the one hand, it can be understood as an absolute state of being. Within Hindu absolutism, for example, it is Brahman, the undifferentiated Absolute. Within Buddhist metaphysics, fundamental reality is Sunyata, or the Void.
