“We know so very little about this strange planet we live on, this haunted world where all answers lead only to more mystery.”

“Ours is a world of nuclear giants and ethical infants. We know more about war than we know about peace, more about killing than we know about living. We have grasped the mystery of the atom and rejected the Sermon on the Mount.”

“Man is not an omipotent master of the universe, allowed to do with impunity whatever he thinks, or whatever suits him at the moment. The world we live in is made of an immensely complex and mysterious tissue about which we know very little and which we must treat with utmost humility.”

“It is not enough to say that we cannot know or judge because all the information is not in. The process of gathering knowledge does not lead to knowing. A child's world spreads only a little beyond his understanding while that of a great scientist thrusts outward immeasurably. An answer is invariably the parent of a great family of new questions. So we draw worlds and fit them like tracings against the world about us, and crumple them when they do not fit and draw new ones.”

“We lived like the only two people on the planet because we thought we were, I still need to know that... That you are still the only person in my world.”

“And I wanted to know whether it is possible to live a hopeful life in a world riddled with ambiguity, whether we can find a way to go on even when we don't get answers to questions that haunt us”
