This was, by far, the best presentation I've encountered at RMAF. Be patient because there's something for everyone here. This is one of the rare cases where the objectivist and subjectivist can see eye-to-eye. It was even better being there because it was very easy to hear the various types of distortion demonstrated. I'm not so sure how well it comes across on youtube.
Of course, Amir sat front row and asked several questions at the end (He's a "gunner" in law school parlance). Enjoy!
