Answer: Nagarjuna
Notes: Nagarjuna was the author of "Mulamadhyamakakarika". It is the foundational text of the Madhyamaka school of Mahayana Buddhist philosophy. Madhyamaka means ‘the middle way’. The book was written in 150AD. For this book, Nagarjuna took the idea from two philosophies of Buddha: eternalism and annihilationism—the belief that the soul exists forever and that the soul is annihilated at death or between materialism and nihilism. Nagarjuna took this idea and expanded it to create the philosophy that is known as Madhyamaka.
