The first concept I want to talk about is simply how in our discussions we reach truth. Since we spend maybe half of the class discussing it's important to have one of the entries on it. We bicker and banter back and forth on concepts that are very broad, to concepts that are very small. Some people may think that we waste time on the nitty gritty but it's important to look at everything that an author has in front of us. From the class I've learned, "everything was written therefore it has a reason for being there".
The greatest discussions (I think) came from the first thing we read in the school year, "The American Dream", just because it was very weird and not many of us had read anything like it. When we disagreed with this one, it was very difficult because everything seemed to work as evidence for both points. Discussing "Death Of A Salesman" was my next favorite because people developed different opinions about what each thing meant, and most of it could be proved both ways.
