This paper is a study of debate practices as seen in the Nyāyasūtra and a number of commentaries. It concentrates on the ‘Points of Defeat ’, i.e., those occasions that if met in debate would entail defeat. The conditions under which a debater would meet with defeat were discussed widely in India and have also attracted considerable attention from modern scholars. In order to better understand this subject, use is made of some of the intuitions about language and conversation that (...) we owe to the philosopher H. P. Grice as well as of some recent theoretical advances in argumentation theory and informal logic, particularly of those most influenced by Grice’s thought. The Points of Defeat are studied both individually and as a group and it is shown that they point towards the practice of debating as being a rational, cooperative and goal-directed activity.

This paper is a critical review of Jonardan Ganeri’s Philosophy in Classical India.

The works of the Tibetan logician Phya pa Chos kyi seng ge (1109–1169) make abundant use of a particular type of argument that I term ‘argument by parallels’. Their main characteristic is that the instigator of the argument, addressing a thesis in a domain A, introduces a parallel thesis in an unrelated domain B. And in the ensuing dialogue, each of the instigator’s statements consists in replicating his interlocutor’s previous assertion, mutatis mutandis, in the other domain (A or B). I (...) show that such a dialogue involves two parallel arguments that develop in an intersecting zigzag pattern, and discuss the principles involved in the establishment of the conclusion from the perspective of parity of reasoning and analogical argument. I examine the overall rhetorical strategy directing the use of arguments by parallels and the pedagogical and explanatory functions they can serve. I also evaluate the plausibility of their use in Phya pa Chos kyi seng ge’s works mirroring a contemporary practice of oral debate, and reflect on the status of such arguments in the framework of Indo-Tibetan logic.

Chāndogyopaniṣad 6 comprises as many as two out of six renowned “great sayings” : tat tvam asi and ekam evādvitīyam. The question arises as to whether the declared in śruti unity of the Absolute Being is to be understood literally or figuratively. The opponent presents three arguments for the figurative meaning of the words. Maṇḍana advocates the literal sense of the statement. The debate is a typical example of an Indian philosophical scholastic text. Scholasticism in India and scholasticism in medieval (...) Europe share some characteristic features, though they also differ in many ways. (shrink)
