Lately there has been an odd fad going on in the history section at bookstores. It started with histories of inanimate objects. Tea: A History. Gold: A History. Coffee. Phosphorus. Salt. Stuff like that.
Now it's branching out into intangible concepts. I'd picked up Honor: A History earlier, but set it down only a couple chapters in to finish off the Vorkosigan Saga. Now I'm back to read it through, and it is fascinating. In the on-deck circle is Doubt: A History.
