"I believe that many people read science fiction for a sense of participation in the wonders to come. The quest for non-ordinary reality is something more than curiosity and wishful thinking. We are too crowded in our every day lives by replicas of ourselves and by the repetitious artifacts of our days and nights. But we do not quite believe in this prosaic world. Continually we are reminded of the strangeness of birth and death, the vastness of time and space, the unknowability of ourselves. One would like to live differently, more significantly. One would like to participate in events more meaningful than our daily round, feel sensations more exquisite than is our usual lot. One reads science fiction in order momentarily to transcend the dull quality of everyday life. There is a reason behind the search for the ineffable. The death of God is argued by the theologians; but for most of us it is a fact of everyday life. ‘God’ is a word with unfortunate connotations for many. By it I mean the fundamental mystery forever untouched by our rationality.… This mystery is what we do not have any more. Our meagre substitute is the religion of man living on the Earth. We understand our ethical duties very well, we believe in them and try to follow them. But there is the secret sadness still remaining, the sense that we were born to quest, that our essence is unknowable, that we are plant and phantom, creatures of unknown dimensions. But all we come face to face with is our actual condition: we are ghosts smothered in bread and butter."
