Concerned To Reconstruct Past Ideas, Historians Must Approach The Generation That Held Them As The Anthropologist Approaches An Alien Culture. They Must, That Is, Be Prepared At The Start To Find That Natives Speak A Different Language And Map Experience Into Different Categories From Those They Themselves Bring From Home.
