Abstract

The practice of rational debate between philosophers from different traditions, especially between Hindu—Naiyāyika and Mīmāṃsaka—, Buddhist and Jain philosophers, is unique in classical India. Around the 7th c., a pan-Indian consensus was achieved on what counts as a satisfactory justification. The core of such discussions is an inferential reasoning whose structure is such that it ensures that its conclusions are recognised as knowledge statements, irrespective of the obedience of the interlocutor. In this line, stories of conversion following those philosophical debates are commonplace in the narratives of the different traditions and regularly involve the conversion of a royal patron. Beside the influence of argumentative practices on social and political changes, theories of argumentation have deeply influenced the whole edifice of philosophy in pre modern India, since no philosopher can claim a thesis without being committed to defend it in this highly regulated dialogical framework. Moreover, the characterisation, as well as the methods to test the validity of this justification, raised the question of the existence of shared principles and was a battlefield for the different traditions to establish their own conceptions on the constitution of the world and on our ability to know it. The aim of this paper is to provide an overview of the contribution of the minority tradition that is Jainism to the framework of philosophical disputation in India.
