I showed a draft of my presidential address to a friend the other day. He read for a few minutes, then looked up at me and said, “Your address will be remembered long after The Wealth of Nations, Ricardo's Principles, and The General Theory are all forgotten, but not until then!”
Remembering is what we who read, write, and teach history of economics are about. Historians preserve memory; we collect historical facts, organize them, and store them in conceptual filing systems. Remembering accurately and fully is hard work. Memory is tricky. It is always incomplete. It is well known that different witnesses to an event such as a traffic accident can remember the event quite differently, so that their accounts of what happened seem incompatible with each other. They may even appear not to be reports of the same event.
