 There is unanimous agreement that Nāgārjuna (ca 150–250 CE) is the most important Buddhist philosopher after the historical Buddha himself and one of the most original and influential thinkers in the history of Indian philosophy. His philosophy of the “middle way” (madhyamaka) based around the central notion of “emptiness” (śūnyatā) influenced the Indian philosophical debate for a thousand years after his death; with the spread of Buddhism to Tibet, China, Japan and other Asian countries the writings of Nāgārjuna became an indispensable point of reference for their own philosophical inquiries. A specific reading of Nāgārjuna’s thought, called Prāsaṅgika-Madhyamaka, became the official philosophical position of Tibetan Buddhism which regards it as the pinnacle of philosophical sophistication up to the present day.
