“Hersesy is denying the word of God, and the word of God is much more reliably expressed in the natural world as it’s revealed through reason and science than in what I have heard described wonderfully as “the giant book of Jewish fairy stories”

“Horza recalled that the Culture's attitude to somebody who believed in an omnipotent God was to pity them, and to take no more notice of the substance of their faith than one would take of the ramblings of somebody claiming to be Emperor of the Universe. The nature of the belief wasn't totally irrelevant - along with the person's background and upbringing, it might tell you something about what had gone wrong with them - but you didn't take their views seriously.”

“As long as a film stays unmade, the book is entirely yours, it belongs to the writer. As soon as you make it into a film, suddenly more people see it than have ever read the book.”

“The truth is not always useful, not always good. It’s like putting your faith in water. Yes, we need the rain, but too much can sweep you away in a flood and drown you. Like all great natural, elemental forces, the truth needs to be channeled, managed, controlled and intelligently, morally allocated.”

“God, what did any of it matter, in the end? You lived; you died. You were as indistinguishable from a distance as one of these blades of grass, and who was to say more important? Growing, surrounded by your kin, you out-living some, some out-living you. You didn't have to adjust the scale much, either, to reduce us to the sort of distant irrelevance of this bedraggled field. The grass was lucky if it grew, was shone upon and rained upon, and was not burned, and was not pulled up by the roots, or poisoned, or buried when the ground was turned over, and some bits just happened to be on a line that humans wanted to walk on, and so got trampled, broken, pressed flat, with no malice; just effect.”

“On Earth one of the things that a large proportion of the locals is most proud of is this wonderful economic system which, with a sureness and certainty so comprehensive one could almost imagine the process bears some relation to their limited and limiting notions of either thermodynamics or God, all food, comfort, energy, shelter, space, fuel and sustenance gravitates naturally and easily away from those who need it most and towards those who need it least. Indeed, those on the receiving end of such largesse are often harmed unto death by its arrival, though the effects may take years and generations to manifest themselves.”

“Experience as well as common sense indicated that the most reliable method of avoiding self-extinction was not to equip oneself with the means to accomplish it in the first place.”
