"I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar."

"We are closer to God when we are asking questions than when we think we have the answers."

"It is amazing how religion has turned this biblical idea of faith around to mean the exact opposite: into a need and even a right to certain knowing, complete predictability, and perfect assurance about whom God likes and whom God does not like. It seems we think we can have the Infinite Mystery of God in our quite finite pocket."

"Preoccupation is in fact a greater stumbling block than occupation. We are so afraid of open spaces and empty places that we occupy them with our minds even before we are there. Our worries and concerns are expressions of our inability to leave unresolved questions unresolved and open-ended situations open-ended. They make us grab any possible solution and answer that seems to fit the occasion. They reveal our intolerance of the incomprehensibility of people and events and make us look for labels or classifications to fill the emptiness with self-created illusions."
