Ajñana

Ajñāna (, (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.

==Sources== All of our knowledge of the Ajñāna come from the Buddhists and Jain sources. The Ajñāna view points are recorded in Theravada Buddhism's Pāli Canon in the Brahmajala Sutta and Samaññaphala Sutta and in the Sūyagaḍaṃga of Jainism. Along with these texts, the sayings and opinions of the Sceptics (ajñānikāḥ, ajñānināḥ) has been preserved by Jain writer Silanka, from the ninth century, commenting on the Sutrakritanga. Silanka considers sceptics "those who claim that scepticism is best" or as "those in whom no knowledge, i.e. scepticism, is evident". Apart from the specific technical meaning, Silanka also uses the word ajñānikah in a more general sense to mean anyone who is ignorant.
