Silhouettes: rhetoric and science?

Science as part of an open society cannot flourish if science becomes the exclusive possession of a closed set of specialists. The problem of scientific rhetoric, however, is that scientific knowledge cannot be everybody's knowledge in volume or in the concepts used and that therefore a loss of information content occurs when scientific knowledge is projected onto the screen of everyday knowledge: science then appears only as a silhouette. Even so silhouettes can convey an important message in relation to a special context under discussion. The particular silhouette selected then becomes a question of truthfulness in scientific rhetoric.
