"The immediate problem with our meat brains is that they have no back-up. We can lose the most precious information we have from one bump on the head or stroke. You want a mind system with back-up that can access other databases."
- Bart Kosko

| Wall in the Air | ||
| An invisible barrier that protects an entire island or city. |
As far as I know, this is the earliest example of this idea in science fiction.
| They only could tell us that they had been taught from the Sun Island, a far-off land of the sea. Sometimes, they said, the tide was low and we could walk on dry rocks to the isle. Sometimes there was a “wall in the air.” Then no one could get there...
“That is the Sun Island. The angel-man lives there.”
Before the bird people slept he ordered the construction of a small, strong stone house, with two great cellars stored with fuel, food and oil. This was built as near the island as possible. The glow of brightness made continual day around it, but warmth hardly penetrated the impassable wall in the air... “This day only the wall in the air is removed. The bird people are asleep. I can take you there quickly!” |

'Chris, the City Fathers are not interested in your welfare; I suppose you know that. They're interested in only one thing: the survival of the city.'
'Drake was the young spatial engineer he employed to terraform the little rock...'
'It diverts integers of the data, the fundamental message-units, so that they no longer agree.'
'Clothes are no longer made from dead fibers of fixed color and texture that can approximate only crudely to the vagrant human figure...'
'Books were just a commodity that had to be produced, like jam or bootlaces.'
