On this day I want to tell you about, which will be about a thousand years from now, there were a boy, a girl and a love story.

You can't really predict the future. All you can do is invent it.

What were we doing here? Traveling hundreds or thousands of light-years, to break our hearts?

A good science fiction story should be able to predict not the automobile but the traffic jam.

I'm pretty catholic about what constitutes science fiction.

If you don't care about science enough to be interested in it on its own, you shouldn't try to write hard science fiction. You can write like Ray Bradbury and Harlan Ellison as much as you want.

My old English buddy, John Rackham, wrote and told me what made science fiction different from all other kinds of literature - science fiction is written according to the science fiction method.
