The Iconoclast's Guide to American History. Well done but there was one thing that drove me nuts listening to this series of lectures. This guy sounds exactly like the campaign director character played by the late Ron Silver on The West Wing--same accent, same pacing, same stridency.
It is a good series of lectures that points out everything that we don't learn in school and all that we tend to forget about the events of American History as we move further away from them and start to paint these events with the brush of modernity.
I remember "the explorers" as being a big thing that was taught in my school system in elementary school and we dutifully learned all the names of the European explorers and where they went, etc. My goodness, we were parochial in our approach to history. So, what was fascinating for me was the scope of these lectures. They went back further into history, covering the ancient Greeks, and they were more global, not limited to European white males. Each lecture covered one explorer or exploration telling the story of the exploration and then commenting on its significance, why it was a pivotal moment human history.
