"Historians do not, as too many of my colleagues keep mindlessly repeating, “reconstruct” the past. What historians do is produce knowledge about the past, or, with respect to each individual, fallible historian, produce contributions to knowledge about the past. Thus the best and most concise definition of history is: “The bodies of knowledge about the past produced by historians, together with everything that is involved in the production, communication of, and teaching about that knowledge."
