Stephen Phillips has devoted his career to excavating some of the most valuable gems of Indian philosophy and bringing them into conversation with contemporary thought. This volume honors him and follows his lead by continuing his lifelong project: faithfully interpreting Sanskrit texts to think along with their authors about ideas that still perplex us today. It features ten new essays focusing on epistemology, logic, and metaphysics from outstanding philosophers and scholars of Sanskrit philosophy, with contributions varying in methodology: both historical and cross-cultural. Further, in addition to essays on Nyaya and Advaita Vedanta, it engages with Navya-Nyaya (“new Nyaya”), an important but understudied part of Indian philosophy. Through these investigations, in conversation with Phillips's groundbreaking work, the contributors show the value of cross-cultural engagement for philosophical progress. The Vindication of the World will be of interest to scholars and advanced students working in Indian philosophy, comparative philosophy, and, more generally, epistemology, logic, and metaphysics.
