By walking, philosophical thoughts come to many writers' mind - Frédéric Gros collects a lot of this kind of stories. Even though some interpretation of Zhuangzi in this book isn't very precise, the author does an excellent work on writing "walking". Marcher, une philosophie is an elegant book, there aren't so many tough terms but the real sense and aura of life in it. Gros is like a guide, leading readers to walk through ancient and modern times. The author reminds you to pay attention to every moment of physical and mental feelings during walking. Thus readers could go on a trip of "thinking about walking".
