“There is a world elsewhere.”

Source: His Dark Materials, The Amber Spyglass (2000), Ch. 26 : The Abyss
Context: Your dæmon can only live its full life in the world it was born in. Elsewhere it will eventually sicken and die. We can travel, if there are openings into other worlds, but we can only live in our own. Lord Asriel’s great enterprise will fail in the end for the same reason: we have to build the Republic of Heaven where we are, because for us there is no elsewhere.

Book VII, Ch. 4
Death Comes for the Archbishop (1927)
Context: The sky was as full of motion and change as the desert beneath it was monotonous and still, — and there was so much sky, more than at sea, more than anywhere else in the world. The plain was there, under one's feet, but what one saw when one looked about was that brilliant blue world of stinging air and moving cloud. Even the mountains were mere ant-hills under it. Elsewhere the sky is the roof of the world; but here the earth was the floor of the sky. The landscape one longed for when one was away, the thing all about one, the world one actually lived in, was the sky, the sky!

A Declaration of the Independence of Cyberspace (1996)
Context: Your increasingly obsolete information industries would perpetuate themselves by proposing laws, in America and elsewhere, that claim to own speech itself throughout the world. These laws would declare ideas to be another industrial product, no more noble than pig iron. In our world, whatever the human mind may create can be reproduced and distributed infinitely at no cost. The global conveyance of thought no longer requires your factories to accomplish.
These increasingly hostile and colonial measures place us in the same position as those previous lovers of freedom and self-determination who had to reject the authorities of distant, uninformed powers. We must declare our virtual selves immune to your sovereignty, even as we continue to consent to your rule over our bodies. We will spread ourselves across the Planet so that no one can arrest our thoughts.
We will create a civilization of the Mind in Cyberspace. May it be more humane and fair than the world your governments have made before.

The Dreamstone, Book One : The Gruagach, Ch. 1 : Of Fish and Fire
Arafel's Saga (1983)
Context: Men changed whatever they set hand to. They wrought their magic on beasts, to make them dull and patient. They brought fire and the reek of smoke to the dales. They brought lines and order to the curve of the hills. Most of all they brought the chill of iron, to sweep away the ancient shadows.
But they took the brightness too. It was inevitable, because that brightness was measured against that dark. Men piled stone on stone and made warm homes, and tamed some humbler, quieter things, but the darkest burrowed deep and the brightest went away, heartbroken.
Save one, whose patience or whose pride was more than all the rest.
So one place, one untouched place in all the world remained, a rather smallish forest near the sea and near humankind, keeping a time different than elsewhere.
