Perhaps we could contribute together a reading list that our children found interesting and spark some discussion on the group?
My kids are almost done with High School. They haven’t been as interested in reading as I was as a child though my son enjoys Science Fiction and some non-fiction.
Of late, my son read “None Dare Call It Conspiracy” as a school assignment and he and I have shared quite a few hours of discussion and a bit of analysis. He and I have agreed to a year or two of self-study before he goes to University. As part of that I have accumulated more books than either he or I could possibly finish in a year or two.
Since he expressed an interested in learning about different religions around the world, I’ve recommended all of the books by Karen Armstrong since they do a reasonably good job exposing ideas of Judaism, Christianity, and Islam. I’m also referring another book that does a wider survey.
As far as Philosophy, I’m recommending the essential works of Plato and Aristotle, but I’m also supplementing that with a series of podcasts from King’s College London called “The History of Philosophy without gaps.” It goes from pre-socratics to modern Philosophy.
There is a wealth of really good stuff out there that can allow kids to dip their toes and get a feel for the questions and skills you need to be a critical thinker.
