This article is first in a series dedicated to issues in the intellectual history of Mīmāṃsā in early modern India and part of a larger effort to broaden the basis for understanding the new formulations of central topics of the Mīmāṃsā textual-ritual complex in this period. It examines how the Varanasi scholar Khaṇḍadevamiśra makes use of Navyanyāya tools of analysis by putting under the microscope the example of his investigation and new formulation of the signification of agent and agency by (...) the verbal affix in his ample analysis of the cognition of the meaning elements of a sentence. Authors of Mīmāṃsā works in the sixteenth and seventeenth centuries gradually and selectively adopt the tools and techniques of cognitive analysis and the characteristic new idiom elaborated by Navyanaiyāyikas a few centuries earlier. This process of adoption arises on the sidelines of the Advaita–Dvaita Vedānta controversy in South India, then subsequently flourishes in Varanasi, as I have followed elsewhere. In his analysis of the topic studied here, Khaṇḍadeva uses the new tools to revisit the Mīmāṃsā tradition in order to advance his new formulation while refuting certain Navyanyāya rival positions.
