Debates, sects and the challenge to Vedic authority

Detail

How many schools were there

• Buddhist texts mention as many as 64 sects or schools of thought. This shows how crowded the world of ideas was in the 6th century BCE.
• These were not small fringe groups. Speculation in this period ran from idealism (only mind/spirit is real) to materialism (only matter is real) [2].
• Alongside Buddhism and Jainism, two smaller sects were popular for a time — the Ajivikas and the Charvakas (also called Lokayata) [2][3].

The named rival teachers

• Makkhali Gosala (also Goshala Maskariputra) founded the Ajivika sect. He was a friend of Mahavira, the 24th Tirthankara of Jainism [4].
• The Ajivikas were an ascetic sect (people who give up comfort and possessions).
• Their opponents said they taught total determinism — that your chain of rebirths is already fixed, so effort changes nothing. Gosala denied sin and denied free will [2][4].

• The sect lasted a very long time — down to the 14th century [4].

• Purana Kassapa was a naturalist. He denied both virtue and vice, so he denied that human deeds have any moral result at all [2][5].

• Ajita Keshakambalin, a contemporary of the Buddha, taught materialism — no other world after this one [2].
• Charvaka was the school of materialists. They rejected the afterworld, karma, moksha (liberation), the authority of the Vedas, and any soul that survives death [3].
• Key contrast to remember: the Ajivikas said effort is useless because fate decides; the Buddha and Mahavira said the opposite — effort by the individual is exactly what works.

Where the debates happened

• Teachers travelled from place to place. They tried to convince one another, and also convince ordinary laypersons.
• Debates took place in the kutāgāraśhālā — the word literally means a hut with a pointed roof.
• Debates also happened in groves where travelling mendicants (wandering holy men who begged for food) stopped to rest.

The stakes of winning a debate

• If a philosopher defeated a rival, the rival's followers became his disciples.
• So a single debate could move a whole block of supporters from one teacher to another.
• This is why support for a sect could grow and shrink over time. Numbers were never fixed.
• It also explains the travelling: a teacher had to keep showing up and keep winning.

What Mahavira and the Buddha shared

• Both questioned the authority of the Vedas. The Vedas were not accepted as the final proof of anything.
• Both emphasised individual agency — that is, each person acts for themselves.
• Men and women could strive for liberation from worldly existence.
• This stood in marked contrast to the Brahmanical position, which held that a person's existence was determined by birth in a specific caste and gender.
• Brahmanical view: what you are born as decides what you can become.
• Heterodox view: what you do decides what you become.
• This is the single sharpest dividing line in the whole debate.

Debate did not stop after the founders died

• Inside Buddhism itself the arguing continued and produced formal splits.
• The second Buddhist council was held at Vaishali (in present-day Bihar), said to be 100 years after the Buddha's death [5][6].
• The dispute was about relaxed rules of discipline followed by the monks of Vaishali.
• The majority voted against the Vaishali rules. The defeated minority walked out [6].
• That defeated minority formed the Mahasanghika school, splitting from the Sthaviravadins ("followers of the Way of the Elders") [5][6][7].

• Britannica dates this first separation to the 4th century BCE [5].

• After this council a number of Buddhist schools appeared over many years — the tradition of the "eighteen schools". Each had slightly different doctrine and a slightly different monastic code [7].

• A second big split came when the Sarvastivadins ("all is real") separated from the Vibhajyavadins ("Doctrine of Distinctions") [5].
• Over the next seven centuries the Mahasanghikas themselves subdivided into the Lokottaravadins, Ekavyavaharikas and Kaukkutikas [7].

Prelims Hooks

• Buddhist texts mention as many as 64 sects or schools of thought.
• Kutāgāraśhālā literally means a hut with a pointed roof — the usual venue for philosophical debate.
• Rule of debate: the defeated rival's followers became the winner's disciples.
• Makkhali Gosala (Goshala Maskariputra) founded the Ajivika sect and was a friend of Mahavira [4].
• The Ajivika sect survived until the 14th century [4].
• Charvaka, also called Lokayata, rejected the afterworld, karma, moksha, the authority of the Vedas, and the soul [3].
• Purana Kassapa — naturalist who denied virtue and vice; Ajita Keshakambalin — materialist contemporary of the Buddha [2].
• The second Buddhist council at Vaishali, c. 100 years after the Buddha's death, caused the Mahasanghika–Sthaviravadin split [5][6].
• Mahavira and the Buddha both held that men and women could strive for liberation.
• Mahasanghika offshoots: Lokottaravadins, Ekavyavaharikas, Kaukkutikas [7].

Mains Points

• Debate as a social institution, not just a philosophy seminar. The winner-takes-the-followers rule made public debate the main way religious support moved. Sects were therefore unstable in size, and teachers had to keep travelling to defend their position — this explains the mobile, argumentative character of 6th-century BCE religious life.
• Two different attacks on Vedic authority. Buddhism and Jainism rejected the Vedas but kept karma and liberation and added strong individual effort. Charvaka rejected the Vedas and karma and liberation altogether [3]. The Ajivikas rejected free will itself [2]. So "heterodox" is not one position — an answer should separate these strands.
• Birth versus effort as the real fault line. The Brahmanical order tied a person's existence to birth in a caste and gender. Mahavira and the Buddha opened liberation to men and women through their own striving. This shift from ascribed status to personal effort is the main social significance of the period and links directly to later Bhakti and reform movements.
• Internal dissent shows the debating habit was carried inward. The Vaishali council split Buddhism over monastic discipline, not over metaphysics [6], and produced the eighteen-schools tradition [7]. The same culture that let the heterodox challenge the Vedas also let Buddhists challenge one another.
