Udayana

Udayana also known as Udayanācārya (Udyanacharya, or "Master Udayana) lived in the 10th century, in Kariyan village in Mithila, near present day Darbhanga, Bihar state, India. Udayana was a very important Hindu logician who attempted to reconcile the views held by the two major schools of logic (Nyaya and Vaisheshika). This became the root of the Navya-Nyāya school of the 13th century, established by Gangesha Upadhyaya (“New Nyāya”) school of “right” reasoning, which is still recognized and followed in some regions of India.
