Some will have trouble with this book. It is a philosophical treatise afterall. However, its simple structure eases the pain of what might be considered a dull read. Composed of thirty-three short essays discussing why philosophers think and walk, how protesters changed the world by walking and why people simply enjoy a pleasant walk, this book is really an entertaining celebration of the power of walking. Originally published in French, it became a “best-seller” in France. This in itself suggests a certain intellectual sophistication, which might separate French “macheurs” from North America walkers. OK, I have a European bias. In fact, I will have to re-read this book often to absorb its density, because it does bring a certain heightened sense of purpose to my walks.
