Slide 1
Seeing smoke can lead to a claim about fire
Nyaya is an Indian philosophical tradition concerned with reasoning. Its smoke-and-fire example asks how seeing one thing can justify a claim about another.

Smoke appears above a distant hill. You conclude that there is fire there. The conclusion goes beyond what you directly see: smoke is the evidence, while fire is what you infer from it.
Slide 2
Separate the claim from the reason for it
The hill has fire is the claim; the hill has smoke is the offered reason. An argument needs both, rather than a claim alone.

The claim identifies what is to be established: the hill has fire. The reason supplies the proposed evidence: it has smoke. Naming both lets a listener ask whether the observation is reliable and whether it actually supports the claim.
Slide 3
Nyaya makes five parts of the argument explicit
A Nyaya presentation sets out claim, reason, example, application and conclusion. Together they show how the inference is supposed to work.

The presentation proceeds through a claim, a reason, an example expressing the smoke-fire relationship, an application of that relationship to the hill, and a conclusion. Each part makes explicit something a shorter statement might leave for the listener to supply.
Slide 4
The example must support a dependable connection
A smoky hearth can illustrate the smoke–fire connection. But one convenient example cannot establish every inference; the link must bear the argument’s weight.
More to Read
An example such as a smoky hearth helps explain the relationship, but one convenient example cannot establish every inference. The argumentative burden lies in showing that the reason is dependably connected to what it is supposed to establish.
Slide 5
Showing the steps gives others places to question them
Listeners can question the evidence, the general connection and its application. Nyaya’s structured inference makes those parts of an argument available to inspect.
More to Read
This Nyaya presentation turns an inference into a public sequence of commitments. A listener can challenge the observation, the general connection or its application. It is one important form within a long Indian logical tradition, not a summary of that entire tradition.
