I tried to read this a couple of years ago. Maybe it will go better if I follow along with others this time.
Liam started talking to me about Spinoza and Hobbes the other day. At his college this year they are talking about government and rights and responsibilities of rulers. If you go here and scroll down to the junior year you can see some of the books on his course list. This is really interesting stuff. I totally missed Government in high school because I was getting a British O-Level education in Switzerland at the time. My history teacher Mr Schumann was a first rate teacher and I still remember all kinds of things I learned about the 20th century, but nothing much about civics or political theory. It's one of those areas where I wish I could fit an extra 3-4 hours in the day because in one way, it's not necessary to wade through all the erroneous theories of the Enlightenment but in another way it would probably explain a lot that's puzzling about the way the world looks today. I know Charlotte Mason was quite well-read in the Enlightenment and post-Enlightenment philosophers and knowing more about those would help me understand her writings better too.
Sigh... anyway, just for starters, I think I'll try to keep up with the Economics in One Lesson schedule. We'll see. Even though I didn't finish the book the first time through, I well remember his premise about watching out for the unintended secondary consequences. I talk to my kids about that quite a bit. The principle applies to schooling and medical interventions and therapeutic interventions like HeadStart, and to parenting as well.
I am just finishing reading Socrates meets Marx by Peter Kreeft. It is a cute series, if you want a readable way to introduce major schools of thought to a highschooler. I am not saying "cute" in a derogatory way, either -- after all, cute used to mean "acute" even up past the turn of the 19th century -- ask my daughter, who is presently reading the Aubrey/Maturin series by Patrick O'Brian. The Peter Kreeft "Socrates" (I've also read The Unaborted Socrates and The Best Things in Life) books are "acute" in bits, and amusing in others, and sometimes a teeny bit hokey, because after all, putting words in the mouth of Socrates and Marx and Descartes and various others is no easy task. I know I couldn't do it.
