Space! An emptiness. A mighty emptiness, filled with flaming suns that were called the stars. And across that space, across the stretches of it too vast to be measured by the mile, too great to be measured by anything but light-years, the space crossed by light in the passage of a year, sped a thing that was called a ship—not the Ship, Ship with a capital S, but simply a ship, one of many ships.

A ship from the planet Earth—not from the sun itself, not from the star, but from one of many planets that circled round the star.

It can't be, he told himself. It simply cannot be. The Ship can't move. There can't be space. There can't be emptiness. We can't be a single dot, a lost and wandering mote in the immensity of a universal emptiness, dwarfed by the stars that shine outside the port.

Because if that were so, then they stood for nothing. They were just casual factors in the universe. Even less than casual factors. Less than nothing. A smear of wandering, random life lost amid the countless stars.

Knowledge stored in there, he thought. That's what the instruction sheet had said. Knowledge stored on spools of tape, knowledge that was drummed into the brain, that was impressed, implanted, grafted on the brain of a sleeping man.

And this was just the beginning. This was only the first lesson. This was just the start of the old dead knowledge scrapped so long ago, a knowledge stored against a day of need, a knowledge hid away. And it was his. It lay upon the spools, it lay within the cap. It was his to take and his to use—and to what purpose? For there was no need to have the knowledge if there were no purpose in it.

And was it true?

That was the question.

Was the knowledge true?
