However, beware of the lightness of a manual. Kant's thought has its complexities (one probably should default to reality itself) and Luc Ferry does that translate back into our contemporary language, the better to take the momentum. Impatient readers are cautioned. And because those who have the patience to read and reread this book will appreciate the structure that animates it: rather than give us a simple summary of the work of Kant, Luc Ferry, presents a rigorously philosophical enterprise apart whole because after his interpretative choices we understand why the voice of Kant "continues to speak to us through the centuries." And it it ''s perhaps the most valuable lessons in philosophy.
