In many cases, close examination proves that the knowledge presented as “new” actually addressed issues that earlier theories and methods treated in a much more comprehensive theoretical manner. It is just that now they turn up in a more current and fitting practical surround, and they present themselves from a practical-applications perspective. The danger is that lots of knowledge will be constantly found anew. This underlines the fact that earlier findings were not transmitted to the new generation very successfully, thus representing a lack of knowledge transfer.
