“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.”

“The world, whatever we might think about it terrified by its vastness and by our helplessness in the face of it, embittered by its indifference to individual suffering—of people, animals, and perhaps also plants, for how can we be sure that plants are free of suffering; whatever we might think about its spaces pierced by the radiation of stars, stars around which we now have begun to discover planets, already dead? still dead?—we don’t know; whatever we might think about this immense theater, to which we may have a ticket, but it is valid for a ridiculously brief time, limited by two decisive dates; whatever else we might think about this world—it is amazing.”

“Unlike him I had been unable to escape into the simple complexities of science. All he had to do was solve the mystery of the universe, which may be difficult but is not as difficult as living an ordinary life...(How happy scientists are! Why didn't we become scientists, Percival? They confront problems which can be solved. We don't know what we confront. Does it have a name?)”

“Whatever we do, we must not treat the Great Commission like it's the Great Suggestion.”

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

“We can't get rid of any part of ourselves. If we want to change our relationship with food--which is part of who we are--we must first turn towards it and treat it with utmost kindness.”
