有一技之长者鄙读书,无知者羡读书,唯明智之士用读书,然书并不以用处告人,用书之智不在书中,而在书外,全凭观察得之。读书时不可存心诘难作者,不可尽信书上所言,亦不可只为寻章摘句,而应推敲细思;书有可浅尝者,有可吞食者,少数则须咀嚼消化。 There is a skillful person who reads a book, an ignorant person reads a book, a wise man uses a book, but a book does not use a person to tell a person. The wisdom of the book is not in the book, but outside the book, it is all observed. When reading a book, you must not try to make it difficult for the author to not believe what the book says, nor just to pick a sentence for the chapter, but to ponder over it carefully. Those who have a good taste of the book can eat it, and a few must chew.
