And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo.

The factory is a bakery and he operates the slicing machines. And sometimes a slicer is not working fast enough but the bread keeps coming and there is a blockage. I sometimes think of my mind as a machine, but not always as a bread-slicing machine. It makes it easier to explain to other people what is going on inside it.

I think good books have to make a few people angry.
