Last night I thought about all the kerosene I've used in the past ten years. And I thought about books. And for the first time I realized that a man was behind each one of the books. A man had to think them up. A man had to take a long time to put them down on paper. And I'd never even thought that thought before...It took some man a lifetime maybe to put some of his thoughts down, looking around at the world and life, and then I come along in two minutes and boom! it's all over.

Don't think about things, just do them; don't predict them, just make them.

The years go by. The time, it does fly. Every single second is a moment in time that passes. And it seems like nothing - but when you're looking back ... well, it amounts to everything.

A science fiction story is just an attempt to solve a problem that exists in the world, sometimes a moral problem, sometimes a physical or social or theological problem.

I have fun with ideas; I play with them.

If we try to deny the darkness in our souls then we'll become completely dark.

People ask me to predict the future, when all I want to do is prevent it. Better yet, build it. Predicting the future is much too easy, anyway. You look at the people around you, the street you stand on, the visible air you breathe, and predict more of the same. To hell with more. I want better.
