This is the second article in the series entitled Nature: The Supreme Logician. This article discusses various notions associated with the language of science. In particular, the concept of a rational description, hypotheses, indirect verification, theories, scientific speculation, discipline languages, Mill induction, improper theories, and the notion of a model are discussed. The concept of falsifiability and hypothesis modification are delineated.
