经验丰富的人读书用两只眼睛，一只眼睛看到纸面上的话，另一只眼睛看到纸的背面。

The truth about the world is that anything is possible. Had you not seen it all from birth and thereby bled it of its strangeness it would appear to you for what it is. A hat trick in a medicine show. A fevered dream. A trance bepopulate with chimeras having neither analogue nor precedent. An itinerant carnival. A migratory tentshow whose ultimate destination after many a pitch in many a mudded field is unspeakable and calamitous beyond reckoning.

一个好的抽象是捕捉概念的本质方面，同时忽略无关的细节。
