I am reading this book, and frankly it is very interesting, very exciting, very readable and very clear. It presents the history of the philosophy of very accessible and highly motivating way through 5 important steps. Luc Ferry wants to invite us to continue our philosophical curiosity by ourselves. So very good book for everyone! I think in part, or Sophie's World Philosophy for Dummies does not fully comply with their mission (that of clarity). Luc Ferry leads her to wonder! Congratulations!
