Part of how we come to take command of our world, to take command of our environment, to make these tools by which we're able to do this, is we ask ourselves questions about it the whole time. So this man starts to ask himself questions. "This world," he says, "so who made it?" Now, of course he thinks that, because he makes things himself. So he's looking for someone who would have made this world. He says, "Well, so who would have made this world? Well, it must be something a little like me. Obviously much much bigger. And necessarily invisible. But he would have made it. Now why did he make it?" Now we always ask ourselves "why?" because we look for intention around us; because we always intend– we do something with intention. We boil an egg in order to eat it. So we look at the rocks, and we look at the trees, and we wonder what intention is here even though it doesn't have intention.

Having solved all the major mathematical, physical, chemical, biological, sociological, philosophical, etymological, meteorological and psychological problems of the Universe except for his own, three times over, [Marvin] was severely stuck for something to do, and had taken up composing short dolorous ditties of no tone, or indeed tune. The latest one was a lullaby.
Marvin droned,
Now the world has gone to bed,
Darkness won't engulf my head,
I can see in infrared,
How I hate the night.
He paused to gather the artistic and emotional strength to tackle the next verse.
Now I lay me down to sleep,
Try to count electric sheep,
Sweet dream wishes you can keep,
How I hate the night.

The device [electronic I Ching calculator] also functioned as an ordinary calculator, but only to a limited degree. It could handle any calculation which returned an answer of anything up to 4. ...anything above 4 it represented merely as "A Suffusion of Yellow." Dirk was not certain if this was a programming error or an insight beyond his ability to fathom, but he was crazy about it anyway, enough to hand over twenty pounds of ready cash for the thing.
