meaning of theory

meaning of theory

A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn’t, the theory is refined or rejected. The longer the central elements of a theory hold–the more observations it predicts, the more tests it passes, the more facts it explains–the stronger the theory.

The theory of meaning may either attempt to explain what it is to have the concepts expressible in a particular language (full‐blooded theory), or merely to associate concepts with words in that particular language (modest theory). A theory of meaning suggested by Davidson, according to which knowing the meaning of a sentence consists in the ability to produce a T‐schema for that sentence, is a modest theory. But such a theory will be either a translation manual (in which case it does not explain the knowledge of language), or will have to be construed holistically (in which case a systematic account of the mastery of language is impossible).
