I started reading M. Angot's introduction to his translation of the Nyayabhasya. The text is fascinating because and although it is very provocative. The author maintains that Indian philosophers were first of all performers, namely they performed debates. They were not contemplative sould detached from worldly worries, but rather sanguinely engaged in confrontations. The standard form of expression in Sanskrit, writes the author, is indeed that of confrontation.
Angot then adds, without any apparent explanation, that philosophy after the Nyayabhasya "surrendered to religion". Abhinavagupta could be a great philosopher, but only insofar as he was first of all a theologian, and so on. On the contrary, authors until the NBh could doubt everything, including the Veda. They were, Angot suggests, like the sophists in Ancient Greece.
What do readers think? So much food for thought and I've only read the first 12 pages;-)
