Given below are two statements: Statement I: According to Naiyayikas (Indian Logicians), in inference for others, five steps are required. Statement II: According to Naiyayikas, in inference for oneself, only three steps are required. In the light of the above statements, choose the correct answer from the options given below:
Both Statement I and Statement II are true
Understanding Naiyayika Inference (Anumana)
The question asks about the process of inference, known as Anumana, according to the Naiyayika school of Indian philosophy (Indian Logicians). The Naiyayikas developed a detailed theory of knowledge, and inference is considered a crucial means of valid knowledge (Prama).
Naiyayika logic distinguishes between two types of inference:
- Svarthanumana: Inference for oneself.
- Pararthanumana: Inference for others.
These two types differ primarily in their presentation and the number of explicit steps involved.
Statement I Analysis: Inference for Others (Pararthanumana)
Statement I says: "According to Naiyayikas (Indian Logicians), in inference for others, five steps are required."
Pararthanumana is the process where one person conveys their inference to another person using a structured argument. This is essentially a formal syllogism in Naiyayika logic, known as the Panchavayava (five-membered argument). The purpose is to demonstrate the inferential conclusion convincingly to someone else.
The five steps (members) of Pararthanumana are traditionally listed as:
- Pratijna (Proposition): Stating the thesis to be proved. Example: The hill has fire.
- Hetu (Reason): Stating the reason for the thesis. Example: Because it has smoke.
- Udaharana (Example): Providing a universal concomitance (relation between reason and thesis) with an example. Example: Wherever there is smoke, there is fire, as in a kitchen hearth.
- Upanaya (Application): Applying the universal concomitance to the present case. Example: This hill has smoke which is invariably associated with fire.
- Nigamana (Conclusion): Restating the thesis as proved. Example: Therefore, the hill has fire.
Since Pararthanumana explicitly involves these five distinct steps to present the argument to others, Statement I is true.
Statement II Analysis: Inference for Oneself (Svarthanumana)
Statement II says: "According to Naiyayikas, in inference for oneself, only three steps are required."
Svarthanumana is the internal mental process of inference for one's own conviction. It does not require the formal, explicit presentation of all five steps. When a person sees smoke on a hill and knows the relation between smoke and fire (Vyapti - universal concomitance), they internally arrive at the conclusion "the hill has fire" without needing to articulate the full five-step argument.
While the internal process might not always be broken down into rigidly defined steps in the same way as Pararthanumana, the core components leading to the inference for oneself can be seen as involving fewer stages than the five-step formal argument. Some interpretations simplify this internal process into stages like:
- Perception of the reason (Hetu) in the subject (e.g., seeing smoke on the hill).
- Recollection of the universal concomitance (Vyapti) between the reason and the inferred property (e.g., remembering "where there is smoke, there is fire").
- The resulting inference or conclusion (e.g., concluding "the hill has fire").
These three stages represent the essential cognitive moves required for Svarthanumana. While not always described as explicit "steps" in all texts, compared to the five formal steps of Pararthanumana, the process for oneself is condensed and can be understood as involving these core components. Therefore, accepting the premise that "only three steps are required" aligns with this understanding of the simplified internal process compared to the external presentation.
Based on this understanding, Statement II is also true in the context of the question.
Conclusion on Statements
Statement I correctly identifies that Pararthanumana (inference for others) requires five steps according to Naiyayika philosophy.
Statement II, reflecting a common simplified view of the internal process, states that Svarthanumana (inference for oneself) requires only three steps.
Both statements accurately describe aspects of Naiyayika inference as understood in many contexts.
Revision Table: Naiyayika Inference Steps
| Aspect | Svarthanumana (Inference for Oneself) | Pararthanumana (Inference for Others) |
|---|---|---|
| Purpose | Gaining conviction for oneself | Convincing others |
| Process | Internal, mental process | External, structured argument |
| Number of Explicit Steps (as per statements) | Three steps (core components) | Five steps (Panchavayava) |
Additional Information on Naiyayika Logic
The Naiyayika school is famous for its rigorous development of logic and epistemology. Key concepts related to inference include:
- Vyapti: The universal and necessary relation between the reason (Hetu) and the inferred property (Sadhya). This is the foundation of inference.
- Hetvabhasa: Fallacies of the reason. Naiyayikas classify different types of fallacies that can vitiate an inference.
- Tarka: Hypothetical reasoning or reductio ad absurdum, used to support the certainty of Vyapti.
Understanding these concepts provides a deeper insight into the structure and validity of inference in Naiyayika philosophy, highlighting its systematic approach to knowledge.
Important Questions from Indian Logic
Given below are two statements:
Statement I: According to Classical Indian Logicians (Naiyāyikas) the inference from the effect of the cause is called Purvāvāt.

In light of the above statements, choose the correct answer from the options given below:
Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A) : The Naiya̅yikas did not give separate treatment of the inductive methods, as the western logicians have done.
Reasons (R) : According to Nya̅ya school universal propostions are obtained from perception itself by one of the forms of extra-ordinary perception.
In the light of the above statements, choose the correct answer from the options given below:
