Nyaya Darshan was founded by the ancient Indian sage, Gautama, also known as Akṣapāda Gautama, around the 2nd century BCE. Gautama's work, known as the Nyaya Sutras, is the primary text of Nyaya philosophy. The Nyaya Sutras is a comprehensive treatise on epistemology, metaphysics, and logic. Over time, Nyaya Darshan evolved and was influenced by other philosophical traditions, including Buddhism and Jainism.
