Knowing the Self: Perception, Inference, and Testimony
At a youth philosophy meet in Guwahati, three students debate how we know the self. Speaker 1 says: 'I can see my body, hear my thoughts described, and feel pain. Since perception is the only reliable source of knowledge, the self is just the body; talk of an imperceptible self is meaningless.' Speaker 2 says: 'I infer my self from the fact that memories, desires, and decisions are mine. Just as smoke proves fire, the ownership of mental states proves a self that owns them.' Speaker 3 says: 'The scriptures say the self is distinct from the body, and the scriptures are authoritative because great sages taught them.' The moderator asks the group to separate the pramanas used, to state one Nyaya reply to Speaker 1, and to decide whether Speaker 3's argument is circular. A teacher warns against treating all three as equally strong.
1. Identify the pramanas used by the three speakers and state what each speaker is doing with them.

Speaker 1 uses pratyaksa, perception, and then adds a exclusivist claim that only perception is reliable. That second claim is not itself delivered by perception; it is a philosophical position, often associated with a Charvaka-style rejection of inference and testimony as independent pramanas. Speaker 1 also uses inference rhetorically when concluding 'the self is just the body,' because the conclusion goes beyond what is seen.
Speaker 2 uses anumana, inference. The stated pattern is: mental states are owned; ownership requires an owner; therefore there is a self that owns them. The comparison with smoke and fire signals an inference from a mark to what is marked. Speaker 3 uses sabda, verbal testimony, citing scriptures and the sages who taught them.
The three are not equally strong as presented. Speaker 1's perceptual evidence about the body does not by itself establish that only the body exists. Speaker 2's inference needs a defensible invariable concomitance. Speaker 3's testimony needs a non-circular account of authority.
2. Give one Nyaya reply to Speaker 1 and explain whether it defeats the claim that the self is just the body.

A Nyaya reply is that the self is not an object of ordinary perception but is known through inference and through the unity of experience. Perception itself requires a perceiver: seeing, hearing, and feeling pain are states of someone; they are not themselves the body. The body changes and is perceived, while the self is the bearer of perception, memory, and recognition. Nyaya would infer the self from desire, aversion, effort, memory, and cognition, which require a persistent owner.
The reply defeats the simple claim 'I see my body, so the self is the body' by showing that seeing the body does not identify the self with the body. But it does not by itself prove every Nyaya claim about the self's properties. It shifts the burden: Speaker 1 must show why the inference to a self is invalid, not merely why the self is not seen.
3. Is Speaker 3's argument circular? What would be needed to make testimony a legitimate pramana here?
Read the worked answer
As stated, the argument is circular. The scriptures are said to be authoritative because great sages taught them, and the sages are treated as authoritative because they are associated with the scriptures. That reasoning moves in a circle: the authority of the text is supported by the authority of the teachers, whose authority is supported by the text.
To make sabda legitimate, one would need independent grounds for trusting the speaker: the sages must be shown to be reliable, free from deception and error, and consistent with other pramanas. Nyaya accepts testimony as a pramana when it comes from a trustworthy person and is not contradicted by perception or inference. In the debate, Speaker 3 has asserted authority rather than established it. The argument is therefore weaker than Speaker 2's inference, though Speaker 2's inference still needs its own concomitance to be defended.
