All reading should be nonrequired. At least for the true reader—for reading is a natural function, much like breathing. If every book we encounter is a blind date, then love stories statistically will be outnumbered by the disappointments. But for the true reader, curiosity becomes an essential spiritual function and mystery its ultimate goal. In our books, we seek not answers, really, to that nebulous longing our heart feels eternally; we actually seek the great questions.
