Nyāya: means of knowledge and testing inference

Philosophy of science: models, explanation and testing

A model can predict accurately without telling us every cause, and a failed prediction does not identify its own source of failure.

Learning outcome: Identify what a model represents, reconstruct the logic of a test, and explain when revising an assumption is informative rather than an excuse to avoid evidence.
