“Sin is in the wish to do no harm.”

“Darling, I wish I could help you. Try to remember this: to live, you need every experience. Some will come in glory and in beauty, and some in pain and what seems like ugliness. But - they are. Life consists of opposites in balance.”

“They have not forgotten the Mysteries,' she said, ‘they have found them too difficult. They want a God who will care for them, who will not demand that they struggle for enlightenment, but who will accept them just as they are, with all their sins, and take away their sins with repentance. It is not so, it will never be so, but perhaps it is the only way the unenlightened can bear to think of their Gods.'Lancelot smiled bitterly. ‘Perhaps a religion which demands that every man must work though lifetime after lifetime for his own salvation is too much for mankind. They want not to wait for God's justice but to see it now. And that is the lure which this new breed of priests has promised them.'Morgaine knew that he spoke truth, and bowed her head in anguish. ‘And since their view of a God is what shapes their reality, so it shall be–the Goddess was real while mankind still paid homage to her, and created her form for themselves. Now they will make for themselves the kind of God they think they want–the kind of God they deserve, perhaps.'Well, so it must be, for as man saw reality, so it became.”

“The Goddess has a fourth face. It is secret, and you should prey, as I do, as I do Igraine, that Morgause will never wear that face.”

“Of all things we mortals are called upon to do, the most difficult is forgiveness; in order to truly do it, you will probably have to behave as if you already have forgiven for quite a while before you have actually done so.”

“I think too many people presume to read the divine Scriptures and fall into such terrors as this,' said Patricius sternly. 'Those who presume on their learning will learn, I trust, to listen to their priests for the true interpretations.'The Merlin smiled gently. 'I cannot join you in that wish, brother. I am dedicated to the belief that it is God's will that all men should strive for wisdom in themselves, not look to it from some other. Babes, perhaps, must have their food chewed for them by a nurse, but men may drink and eat of wisdom for themselves.”

“By and large, the kind of science fiction which makes tomorrow's headlines as near as this morning's coffee has enlarged popular awareness of the modern, miraculous world of science we live in. It has helped generations of young people feel at age with a changing world.But fashions change, old loves return, and now that Sputniks clutter up the sky with new and unfamiliar moons, the readers of science fiction are willing to wait to read tomorrow's headlines. Once again, I think, there is a place, a wish, a need for the wonder and color of the world way out. The world beyond the stars. The world we won't live to see. That is why I wrote The Door Through Space.”
