Review Questions

• How does the concept of hetu relate to the process of anumāna in Nyāya logic?
  • The concept of hetu is directly tied to anumāna, which is the process of inference. Hetu serves as the reason that supports the inference, acting as a bridge between premises and conclusions. For an inference to be valid in Nyāya, it must include a reliable hetu that logically justifies the conclusion drawn from observed premises.
• What criteria must a hetu meet to be considered valid in Nyāya epistemology?
  • In Nyāya epistemology, a valid hetu must fulfill specific criteria: it should be relevant to the conclusion it supports, provide a necessary connection between premises and conclusion, and be reliable across similar cases. This ensures that arguments built upon such reasons are sound and can withstand scrutiny during debates or discussions.
• Evaluate the significance of hetu in shaping the nature of reasoning and debate within the Nyāya school.
  • Hetu plays a fundamental role in shaping reasoning and debate within the Nyāya school by serving as a critical component for validating knowledge claims. By establishing clear connections between premises and conclusions through valid reasons, hetu enhances clarity and rigor in logical discussions. This emphasis on structured reasoning allows for more robust dialogues and helps distinguish well-supported arguments from those that lack sufficient justification, thereby enriching philosophical discourse.
