Joe & Charlie suggest that there is a 5th column.
"Putting out of our minds the wrongs others had done, we resolutely looked for our own mistakes."
(67)
I think the problem with stopping at a 3rd column is this
"The first thing apparent was that this world and its people were often quite wrong. To conclude that others were wrong was as far as most of us ever got. The usual outcome was that people continued to wrong us and we stayed sore. Sometimes it was remorse and then we were sore at ourselves. But the more we fought and tried to have our own way, the worse matters got. As in war, the victor only seemed to win. Our moments of triumph were short-lived."
For me the 4th column was an essential part of finding the truth and the lies.
