Describing machines and complex systems...

"They are alive, she thought, but their souls operate them from remote control.  Their soul is in every man who has the capacity to equal this achievement. Should the soul vanish from this earth, the motors would stop, because that is the power which keeps them going - not the oil under the floor, the oil that would become primeval ooze again - not the steel cylinders that would become stains of rust on the walls of the caves of shivering savages - the power of a living mind - the power of thought and choice and purpose."

Dagny Taggert, from Ayn Rand's Atlas Shrugged.
