There are six orthodox Hindu philosophical schools. Nyaya is one of these schools. At some point, the Nyaya philosophy got heavily criticized by the Advaita school. It led to the reformation, where Nyaya philosophers reflected and critically examined their own philosophy. As a result, they came up with a better version of Nyaya philosophy, known as the Navya Nyaya school. Scholars from Bengal, specifically from Nabadwip, played a vital role in this revitalization of the Nyaya school. One of the founders of this Navya Nyaya school was Raghunatha Shiromani from Nabadwip. He lived in the 15th-16th century.
In which philosophical aspects Navya Nyaya school differ from the Nyaya school? How did Navya Nyaya (or Nyaya v2.0, if I may say) overcome its weakness? How did it plug its loopholes? So much so that they became a solid philosophical school, which efficiently dealt with its rival schools and remained relevant till the 18th century.
