Talk by Martin W. Lewis on October 27, 2013 at the Oakmont Sunday Symposium. Historical linguistics, along with archeology and genetics, provide one of the main windows into the deeper reaches of the human past. This allows us to partially reconstruct the historical processes and geographical patterns found in times and places without written records. The most important—and most abused—issue in historical linguistics is the origins and spread of Indo-European, by far the world's largest language family. Dr. Martin Lewis, a senior lecturer in the Department of History at Stanford University, discusses the archaeological and linguistics approaches that allow us to understand the first "Indo-Europeans" for what they really were."
