" A book can be pocketed and discarded, scrawled and torn into pages, lost and bought again. It can be dragged out from a suitcase, opened in front of you when having a snack, revived at the moment of waking, and skimmed through once again before falling asleep. It needs no notice by phone if you can’t attend the appointment fixed in the timetable. It won’t get mad if awakened from its slumber during your sleepless nights. Its message can be swallowed whole or chewed into tiny pieces. Its content lures you for intellectual Why and What adventures and it satisfies your spirit of adventure. You can get bored of it—but it won’t ever get bored of you. "
