To all my gentle readers who have treated me with love for over 30 years, I must say farewell. It has always been my ambition to die in harness with my head face down on a keyboard and my nose caught between two of the keys, but that's not the way it worked out. I have had a long and happy life and I have no complaints about the ending, thereof, and so farewell - farewell.

When I feel difficulty coming on, I switch to another book I'm writing. When I get back to the problem, my unconscious has solved it.

It's just science fiction so it's allowed to be silly, and childish, and stupid. It's just science fiction, so it doesn't have to make sense. It's just science fiction, so you must ask nothing more of it than loud noises and flashing lights.

To me it seems to be important to believe people to be good even if they tend to be bad, because your own joy and happiness in life is increased that way, and the pleasures of the belief outweigh the occasional disappointments. To be a cynic about people works just the other way around and makes you incapable about enjoying the good things.

No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be.

Inspect every piece of pseudoscience and you will find a security blanket.
