R-4 got stuck on the First Law. "Can anyone really protect a human being from all harm whatever?" it thought. "No. It is inevitable that all humans must be injured, contract illnesses and ultimately die. The future can only be averted for humans who are already dead. Ergo..." It took a dozen cops to subdue R-4, after his blood orgy in a department store (83 dead, none injured).

People have laughed at all great inventors and discoverers.

I started writing, or rather, thinking, stories as a child, and at that time the reason was very clear.

Most publishers seem very reluctant to publish short story collections at all; they bring them out in paperback, often disguised as novels.

Anything can happen in SF. And the fact that nothing ever does happen in SF is only due to the poverty of our imaginations, we who write it or edit it or read it. But SF can in principle deal with anything.

This is mainly because I spend a lot of time writing and so don't have much time to read; I hate to waste that time reading what may turn out to be junk food for the mind, when there's so much real writing to be read.

I usually like whatever I've recently finished best.
