The book fascinated him, or more exactly it reassured him. In a sense it told him nothing that was new, but that was part of the attraction. It said what he would have said, if it had been possible for him to set his scattered thoughts in order. It was the product of a mind similar to his own, but enormously more powerful, more systematic, less fear-ridden. The best books, he perceived, are those that tell you what you know already.
(George Orwell – 1984)
