“Some questions don't have answers, which is a terribly difficult lesson to learn.”

“For if there is one lesson worth retaining from the travails of the Cold War and the miseries it brought in its wake, it is the folly of seeking simple answers to complicated questions. It is a lesson which governments still show no sign of learning.”

“There are works which wait, and which one does not understand for a long time; the reason is that they bring answers to questions which have not yet been raised; for the question often arrives a terribly long time after the answer.”

“In some cases we learn more by looking for the answer to a question and not finding it than we do from learning the answer itself.”

“In this age, which believes that there is a short cut to everything, the greatest lesson to be learned is that the most difficult way is, in the long run, the easiest.”

“Some lessons can't be taught, they simply have to be learned.”
