It was refreshing how open he was to accepting that his research, even decades after its original publication, could have lapses and errors. Research, after all, builds on corpus of knowledge existing at the time, and we should expect corrections as the underlying base shifts & corrects itself.

I've never read the book, so I don't have an opinion on it.
