Raghunatha Siromani

Raghunatha Shiromani (c. 1477–1547) was a prominent Indian philosopher and logician. Born in Nabadwip, West Bengal, he became the head of the Ancient Mithila University, also known as Mithila Vidyapeeth. Raghunatha was a descendant of Śulapāṇi and a student of Vāsudeva Sārvabhauma. He is credited with bringing the Navya Nyāya school of thought to its peak of analytical rigor. His philosophical contributions include in-depth analyses of relations, which revealed the true nature of number, and metaphysical studies concerning negation and nonexistence. His most significant work is the Tattvacintāmaṇidīdhiti, a commentary on Gangeśa Upādhyāya's Tattvacintāmaṇi, which itself was a foundational text for the Navya Nyāya school.
