Since we must read books, in my opinion, there is a book on natural education that is very good, and this is also the first book my Emile read.For a long time this book was his entire library, and it will always retain its respectable status.All our talk about the natural sciences is but a commentary on this book.It can also be used to test the improvement of our judgment, and as long as our taste is not spoiled, we will always enjoy reading this book.So, which good book is this?yes.
