This seminar is an exploration of theories of religious action and meta-ethics in late pre-modern Indian philosophy of religion. We will focus on these theories as they are introduced by the Ny?ya philosopher Ga?g??a in his Tattvacint?ma?i. Parimal G. Patil is Professor of Religion and Indian Philosophy at Harvard University, where is Chair of the Department of South Asian Studies. His primary academic interests are in Sanskrit philosophy and the intellectual history of religion in India. In his first two books, Against a Hindu God and Buddhist Philosophy of Religion in India, he focused on interreligious debates between Buddhists and non-Buddhist philosophers in the final phase of Buddhism in India. Currently, he is working on early modern Sanskrit philosophy, especially the work of the New Epistemologists.
