To believe in something not yet proved and to underwrite it with our lives: It is the only way we can leave the future open.

When you stop learning, stop listening, stop looking and asking questions, always new questions, then it is time to die.

None but the weak crave to be better than. Strong men are satisfied with their own strength.

To believe in something not yet proved and to underwrite it with our lives: It is the only way we can leave the future open.

The human heart dares not stay away too long from that which hurt it most. There is a return journey to anguish that few of us are released from making.

To find the point where hypothesis and fact meet; the delicate equilibrium between dream and reality; the place where fantasy and earthly things are metamorphosed into a work of art; the hour when faith in the future becomes knowledge of the past; to lay down one's power for others in need; to shake off the old ordeal and get ready for the new; to question, knowing that never can the full answer be found; to accept uncertainties quietly, even our incomplete knowledge of God; this is what man's journey is about, I think.

The question in crisis or ordeal is not: Are you going to be an extremist? The question is: What kind of extremist are you going to be?
