What is history? What should we make of Edward Carr's observations? How do we take into account how History, as a discipline, has changed in the 19th and 20th centuries? Now that we have had a sampling of David Christian's introduction to "Big History," how should we relate his work to this discussion? Does it make sense to talk about events from millions or billions of years ago as being "History"? Is "Big History" really History or is it something else?
