Abstract

During the past decade or two the influence of theories of language and meaning has made itself felt in almost every field of study, either because, as in the case of psychology and the social sciences, meaning phenomena were part of the subject matter, or because, as in the case of physics and philosophy, the language used in the study demanded analysis and clarification. In recent years there has been developed, especially by H. D. Lasswell and his associates, a technique known as content analysis, which attempts to characterize the meanings in a given body of discourse in a systematic and quantitative fashion.
