This book is on my Xmas wishlist, and I am living in hopes.... In the meantime, I have been relistening to the previous sessions on YouTube. Only through Chapter 3, but I am catching some interesting patterns in the way Dr. Jones structures questions, and important concepts. If this makes things more confusing for some, just please ignore this. But it may help some new people who just now are coming in to switch to more familiar mental things. He talks science-speak [Also, no doubt, pro-historian-language.] "What is an accurate source...." There is no surety that any source is accurate. This is a matter of probabilities and confidence levels. Why is one more 'likely' to be accurate, for what piece of information? Primary and original are higher probability, but...It depends on many things. And confidence levels can change depending on the characteristics of the doc, and on info from other sources. And I loved the "Try to disprove". You think you have found, and now know. But go "Test the hypothesis". Go look for anything that contradicts. If you look, and explore, and have explored thoroughly, and nothing contradicts, then you are good. Until something new possibly emerges.... But you are probably right, and have done your job. Hoping for the book for Xmas, and looking forward to listening to the new sessions!!
