In the Nyāya Sūtra by Akṣapāda Gautama (composed sometime between the sixth century BCE and the second century CE), a three-fold conception of dialogue is discussed. It appears that at the time this was written, dialectic culture was strong in the Sanskritic world. Thus, the rules of dialogue and debate started being codified by several authors, such as Gautama in his Nyāya Sūtra and Caraka (third century BCE) in his seminal Ayurveda work Caraka Saṁhitā. In Gautama's work, he defines three types of dialogue.
