Nagarjuna's Vigrahavyavartani is one of the most important Madhyamaka Buddhist philosophical texts. Jan Westerhoff offers a new translation, reflecting the best current philological research and all available editions, and adds his own philosophical commentary on the text. His nuanced, philosophically sophisticated commentary explains Nagarjuna's arguments in a way that is both grounded in historical and textual scholarship and connected explicitly to contemporaryphilosophical concerns.
