Sanjaya Belatthiputta: The Agnostic Philosopher of Ancient India

Introduction

Sanjaya Belatthiputta was one of the six prominent śramaṇa teachers during the 6th century BCE in northern India, a period known for its vibrant spiritual debates and philosophical experimentation. A contemporary of Gautama Buddha, Mahavira, Makkhali Gosala, Purana Kassapa, Ajita Kesakambali, and Pakudha Kaccayana, he gained recognition as a leading exponent of agnosticism and skepticism.

Unlike other teachers who offered clear doctrines about karma, liberation, or the nature of reality, Sanjaya avoided giving definitive answers to metaphysical or spiritual questions. His approach earned him the label of an agnostic philosopher, and his school of thought is often seen as an early form of philosophical skepticism in India. Although his sect eventually disappeared, Sanjaya’s ideas highlight the diversity of thought in the śramaṇa movement and reflect a questioning spirit that has universal appeal.

Early Life and Background

Details of Sanjaya Belatthiputta’s life are sparse and come mainly from Buddhist sources, particularly the Samaññaphala Sutta in the Dīgha Nikāya. He is believed to have been a wandering teacher in the kingdom of Magadha, active during the reign of King Ajatashatru of Magadha (5th century BCE).

The suffix Belatthiputta suggests that he may have belonged to the Belatthi clan or hailed from a region by that name. Like other śramaṇa leaders of the time, Sanjaya attracted disciples and engaged in debates with rival teachers. His school was not as structured as those of the Buddhists or Jains, but his style of thought left an impression on contemporary intellectual circles.

Philosophy of Sanjaya Belatthiputta – Skepticism and Agnosticism

Sanjaya Belatthiputta’s philosophy can be best described as Ajñānavāda, or the “doctrine of non-knowledge.” Unlike Makkhali Gosala (determinism), Purana Kassapa (amoralism), or Ajita Kesakambali (materialism), Sanjaya’s uniqueness lay in his refusal to take a definitive stance on metaphysical issues.

His philosophical outlook can be summarized as follows:

1. Suspension of Judgment

  • Sanjaya refrained from making any absolute statements about spiritual matters.
  • When asked whether the soul exists, whether the world is eternal, or whether karma has consequences, he neither affirmed nor denied these positions.
  • Instead, he adopted a stance of radical uncertainty, claiming that the truth of such questions could not be known.

2. Fourfold Denial (Agnostic Method)

Sanjaya is often described as using a method of fourfold negation when confronted with philosophical questions:

  • He would not say “it is so.”
  • He would not say “it is not so.”
  • He would not say “it is both so and not so.”
  • He would not say “it is neither so nor not so.”

This radical suspension of judgment reflects a systematic approach to avoiding dogmatic positions.

3. Critique of Doctrinal Certainty

Sanjaya’s philosophy implicitly challenged the claims of other teachers, such as Buddhists and Jains, who presented detailed cosmologies, doctrines of karma, and paths to liberation. By refusing to commit to any absolute truth, he highlighted the limits of human knowledge.

4. Ethical Neutrality

Unlike Mahavira or Buddha, who stressed ethical practices, Sanjaya’s teachings offered no strong moral framework. His philosophy was more concerned with epistemology (theory of knowledge) than with ethics or salvation.

Sanjaya in Buddhist Texts

Buddhist sources often portray Sanjaya in a negative light, describing him as a teacher who avoided answering questions clearly. The Samaññaphala Sutta presents him as a “eel-wriggler” (amarāvikkhepavāda), someone who evades questions by refusing to commit to any answer.

Despite this portrayal, Sanjaya was not without influence. Historical evidence suggests that Sāriputta and Moggallāna, two of the Buddha’s chief disciples, were initially students of Sanjaya before they joined the Buddhist Sangha. This indicates that Sanjaya’s school was well-known and attracted intelligent followers.

Relation with Other Contemporary Teachers

Sanjaya Belatthiputta lived in an era when multiple śramaṇa traditions challenged Vedic orthodoxy. His skepticism contrasted sharply with:

  • Makkhali Gosala’s determinism, which saw fate as supreme.
  • Purana Kassapa’s amoralism, which denied moral consequences.
  • Ajita Kesakambali’s materialism, which denied the soul and afterlife.
  • Pakudha Kaccayana’s atomism, which proposed eternal elements.
  • Mahavira’s Jainism, which emphasized karma and austerities.
  • Buddha’s Middle Path, which emphasized ethical conduct and mindfulness.

While these teachers presented doctrines, Sanjaya’s refusal to speculate made him stand apart as a radical skeptic.

Spread and Followers

Sanjaya’s following was not as widespread as that of Jainism or Buddhism, but he commanded respect as a teacher. His school attracted students who valued intellectual inquiry and freedom from dogmatic positions. The fact that brilliant thinkers like Sāriputta and Moggallāna initially studied under him shows his appeal among seekers of truth.

However, the lack of a structured doctrine or ethical framework limited the growth of his sect. Unlike the organized communities of Jains and Buddhists, Sanjaya’s followers eventually dispersed.

Decline of the Sect

After Sanjaya’s death, his philosophy did not survive as a lasting tradition. The absence of a clear doctrine or soteriological path meant that his teachings were not preserved in a systematic way. Over time, his ideas lived on only in references made by rival traditions, especially Buddhist texts.

Legacy and Significance

Though his sect declined, Sanjaya Belatthiputta remains significant for several reasons:

  • He represents ancient Indian agnosticism, a philosophical position still relevant in modern discussions.
  • His refusal to speculate demonstrates intellectual honesty and humility about the limits of knowledge.
  • His presence enriched the pluralistic debates of the śramaṇa era, forcing rival traditions to clarify their own positions.
  • His teachings remind us that ancient India was not only home to religious dogmas but also to skepticism and critical inquiry.

In this way, Sanjaya Belatthiputta occupies a unique place in Indian philosophy as a thinker who embraced uncertainty as a valid path of inquiry.
