Philosophy of language supplies a coherent analytical framework that integrates contemporary philosophy of science. Philosophers have long distinguished two perspectives in philosophy of language called “object language” and “metalanguage”.

Object language includes most of everyday discourse together with the language of the empirical sciences, and is about the nonlinguistic domains of reality including domains that the particular sciences investigate.

Metalanguage is language about language, either object language or metalanguage.

Much of the discourse in philosophy of science is in the metalinguistic perspective. Important metalinguistic terms include “theory”, “law”, “test design”, “observation report” and “explanation”, which are classifications of language. The computer instructions coded in discovery systems are also metalinguistic expressions, because these systems input, process and output object language for the sciences.
