I read the first few paragraphs and will set it aside for later, but it has always been fascinating to me how writing styles and English language usage varies over the years. I could immediately tell this was an “older” publication based on phrasing and word order, but it still flows nicely and conveys information elegantly (which we somewhat lack in modern writing). Go back 100 years and it’s even more pronounced but still very similar to modern English, 200 years and it’s still quite familiar, but 300 years you’re getting dangerously close to King James/Shakespeare, 400 years it’s almost a different language, etc. I sometimes like to back as far as I can until something becomes completely unintelligible.
