History started around campfires in tribal times. It was a central part of that which kept the tribe thinking itself important, creating cohesion and passing on values. History serves an essential function within society.
Academic history has forgotten what the historic function of history has been up to now. They have gotten into the debunking business using scientific accuracy as a tool. Mr. Moses you are correct. Grand narratives are said to be dead and inaccurate. We need multiple perspectives. There is merit in that, but too much of it, as Dr. Wilson suggested, is a cloak for fabricated Marxist ideology. Rather than serve the central function that history is to serve within a culture, they use history to destroy and debunk the culture. This is enormously destructive.
The popularity of history can be seen in the existence of the history channel. Many best selling books concer historical topics. Many top movies depict historical events. Histories popularity results from its tribal roots. Academic historians who have stripped the positive messages and narrative of history do not sell. This should tell them something; we need our myths.
