 Gipper was also influential as co-editor of an extensive bibliography on "Sprachinhaltsforschung", as linguistics broadly within the Weisgerber tradition has come to be known.Weisgerber can be seen as an epigonic scholar of the German idealistic and romantic traditions alike, that insisted on the compatibility of reason and history and did not play off the first contra the latter.That he did not resist narrowing it down to irrational and silly Germanicism/Celtism does not distinguish him from the academic climate of his times.
