Living in a world that is valued only as gain, an ever-expanding world-as-frontier that has no worth of its own, no fullness of its own, you live in danger of losing your own worth to yourself. That's when you begin to listen to the voices from the other side, and to ask questions of failure and the dark.

It is only when science asks why, instead of simply describing how, that it becomes more than technology. When it asks why, it discovers Relativity. When it only shows how, it invents the atom bomb, and then puts its hands over its eye and says, My God what have I done?

It is good to have an end to journey towards; but it is the journey that matters, in the end.

All knowledge is local, all truth is partial. No truth can make another truth untrue. All knowledge is part of the whole knowledge. Once you have seen the larger pattern, you cannot go back to seeing the part as the whole.

as a writer you are free. You are about the freest person that ever was. Your freedom is what you have bought with your solitude, your loneliness. You are in the country where you make up the rules, the laws. You are both dictator and obedient populace. It is a country nobody has ever explored before. It is up to you to make the maps, to build the cities. Nobody else in the world can do it, or ever could do it, or ever will be able to do it again.

The important thing is not the finding, it is the seeking, it is the devotion with which one spins the wheel of prayer and scripture, discovering the truth little by little.

There was a wall. It did not look important. It was built of uncut rocks roughly mortared. An adult could look right over it, and even a child could climb it. Where it crossed the roadway, instead of having a gate it degenerated into mere geometry, a line, an idea of boundary. But the idea was real. It was important. For seven generations there had been nothing in the world more important than that wall. Like all walls it was ambiguous, two-faced. What was inside it and what was outside it depended upon which side of it you were on.
