This book "asserts that the origin and spread of languages must be examined primarily through the time-tested techniques of linguistic analysis, rather than those of evolutionary biology" and "defends traditional practices in historical linguistics while remaining open to new techniques, including computational methods" and "will appeal to readers interested in world history and world geography."
Aufforderung im Französischen [Requesting in French. A Contribution to the History of Linguistic Politeness]
Ein Beitrag zur Geschichte sprachlicher Höflichkeit
Beihefte zur Zeitschrift für romanische Philologie 358
Linguistic history and cultural history are closely related. This is demonstrated in the study on the phenomenon of linguistic politeness in French requests, e.g. requesting, ordering, suggesting and advising. On a purely linguistic basis, there are indications of a development away from the concept of medieval politeness, which was primarily based on building up close relationships to a concept which among other things takes the personal freedom of the interlocutor into consideration. This change can be explained with general intellectual developments.
