这是一本普通百姓自己写给自己的书。它不仅讲述了我们应当怎样保护环境,而且还讲述了我们应当怎样做“人”。当前,在四处弥漫的商业化的、短视而浮躁的社会风气中,它向读者展示了一种全然不同的理念,一种可望而且可及的清新的精神境界。——梁从诫 This is a book that ordinary people write to themselves. It not only tells us how we should protect the environment, but also tells us what we should do. At present, in a pervasive commercial, short-sighted and impetuous society, it presents the reader with an entirely different idea, a hopeless and refreshing spiritual realm. - Liang Congjie
