The Dangerous Myth of Grade Inflation

After reading Kohn's writing, I found myself very confused on what he was trying to say. He basically had a circular argument and I found it to be very ineffective. First, he takes about how grade inflation isn't real. However, he then goes and talks about how if it was real, it would be a good thing, which takes away from his first argument. By the end of the article, he made at least 4 differ arguments, which were all very strong, but in the end, made his original argument weak and flawed.
