 A problem with any “history of ideas” approach is the validation of the underlying assumption that the concept one is studying has indeed continuity over the history of philosophy. In the case of the historical analysis of information one might ask whether the concept of “informatio” discussed by Augustine has any connection to Shannon information, other than a resemblance of the terms. At the same time one might ask whether Locke’s “historical, plain method” is an important contribution to the emergence of the modern concept of information although in his writings Locke hardly uses the term “information” in a technical sense. As is shown below, there is a conglomerate of ideas involving a notion of information that has developed from antiquity till recent times, but further study of the history of the concept of information is necessary.
