Questions have arisen about the policing of science. Who is responsible for the policing? My answer is: all of us.

Carl took on the military-industrial complex. He campaigned around the world for an end to the production of weapons of mass destruction. To him it was a perversion of science.

One of the first rules of science is if somebody delivers a secret weapon to you you better use it.

But honestly if you do a rigorous survey of my work I'll bet you'll find that biology is a theme far more often than physical science.

Change is the principal feature of our age and literature should explore how people deal with it. The best science fiction does that head-on.

Predicting has a spotty record in science fiction. I've had some failures. On the other hand I also predicted the fall of the Berlin Wall and the rise of fundamentalist Islam... and I'm not happy to be right in all of those cases.

There's no doubt that scientific training helps many authors to write better science fiction. And yet several of the very best were English majors who could not parse a differential equation to save their lives.

In praising science it does not follow that we must adopt the very poor philosophies which scientific men have constructed. In philosophy they have much more to learn than to teach.

The thing about science is that it's an accurate picture of the world.

Science is a self-sufficient activity.
