Margaretha debrunner Posted almost 3 years ago How important is a common vocabulary for sharing ideas, and how do we arrive at one? Do you mean classical in the narrower sense, i.e. Latin and Greek language - yes a wonderful tool to work towards common language or at least raise awareness that there is an issue. It has become a minority skill, but as such hopefully still offers the occasional leven for any serious philosophical, political, cultural discussion. Even if it does not help directly in speaking with people from other cultural traditions it helps to have an open mind and some more clarity about your own use of core words and concept.
