Sañjaya Belatthiputra (Pali: Sañjaya Belaṭṭhiputta; Sanskrit: Sañjaya Vairatiputra; literally, "Sañjaya of the Belattha clan"), was an Indian ascetic philosopher who lived around the 7th-6th century BC in the region of Magadha. He was contemporaneous with Mahavira, Makkhali Gosala, Ajita Kesakambali and the Buddha, and was a proponent of the ajñana school of thought.
Agnosticism is the view or belief that the existence of God, the divine, or the supernatural is either unknowable in principle or unknown in fact. It can also mean an apathy towards such religious belief and refer to personal limitations rather than a worldview. Another definition is the view that "human reason is incapable of providing sufficient rational grounds to justify either the belief that God exists or the belief that God does not exist."
The English biologist Thomas Henry Huxley said that he originally coined the word agnostic in 1869 "to denote people who, like [himself], confess themselves to be hopelessly ignorant concerning a variety of matters [including the matter of God's existence], about which metaphysicians and theologians, both orthodox and heterodox, dogmatise with the utmost confidence." Earlier thinkers had written works that promoted agnostic points of view, such as Sanjaya Belatthiputta, a 5th-century BCE Indian philosopher who expressed agnosticism about any afterlife; and Protagoras, a 5th-century BCE Greek philosopher who expressed agnosticism about the existence of "the gods".
Ajñāna (Sanskrit: अज्ञान, (Vedic) IPA: /ɐd͡ʑ.ɲɑː.nɐ/; (Classical) IPA: /ɐd͡ʑˈɲɑː.n̪ɐ/) is an ancient nāstika, or 'heterodox,' Indian school of agnosticism that embraces radical skepticism. It emerged as a Śramaṇa movement and was a major rival of early Buddhism, Jainism and the Ājīvika school. 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 specialized in refutation without propagating any positive doctrine of their own. Sanjaya Belatthiputta was one of the major proponents of this school of thought.
