“...all religions seek to approach the reality of God through symbols, and these symbols point to the mystery of human life, pushing us beyond ourselves, beyond our limits...there is a danger of stopping short at the sign, which will then become a wall which separates us from truth.”

“The terrible shock of his sentence had in some way broken that wall which separates us from the mystery of things beyond and which we call life.”

“We live on a minute island of known things. Our undiminished wonder at the mystery which surrounds us is what makes us human. In science fiction we can approach that mystery, not in small, everyday symbols, but in bigger ones of space and time.”

“We are nearly always longing for an easy religion, easy to understand and easy to follow; a religion with no mystery, no insoluble problems,no snags; a religion that would allow us to escape from our miserable human condition; a religion in which contact with God spares us all strife, all uncertainty,all suffering and all doubt; in short, a religion without a cross”

“It is not given to us to grasp the truth, which is identical with the divine, directly. We perceive it only in reflection, in example and symbol, in singular and related appearances. It meets us as a kind of life which is incomprehensible to us, and yet we cannot free ourselves from the desire to comprehend it.”

“Words are but symbols for the relations of things to one another and to us; nowhere do they touch upon absolute truth.... Through words and concepts we shall never reach beyond the wall off relations, to some sort of fabulous primal ground of things.”
