“ A book is a physical souvenir, a concrete instantiation of your ideas in a physical object, something that gives your ideas substance and allows them to travel. 书是一种有形的纪念品,是你的想法在有形物体中的具体体现,它赋予你的想法以实质,让它们得以传播。 Seth Godin 赛斯·高汀
“ Earth and sky, woods and fields, lakes and rivers, the mountain and the sea, are excellent schoolmasters, and teach some of us more than we can ever learn from books. 大地与天空,森林与田野,湖泊与河流,高山与海洋,都是优秀的老师,他们教给我们的东西比我们从书本上学到的还要多。 John Lubbock 卢伯克
