As a reader, can you summarize what Alexander is referencing in the two quoted paragraphs that overcomes his initial doubt and decides "after his death is the best time to disagree"?

The only thing I can possibly see is Adams writing "the reader is supposed to be looking for flaws" but it's also clear that Adams is very interested in hearing people's reactions and responses to his work, which he (obviously) can't do any more.
