The Future Depicted In A Good Sf Story Ought To Be In Fact Possible, Or At Least Plausible. That Means That The Writer Should Be Able To Convince The Reader (and Himself) That The Wonders He Is Describing Really Can Come True... And That Gets Tricky When You Take A Good, Hard Look At The World Around You.

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.

That's Really What Sf Is All About, You Know: The Big Reality That Pervades The Real World We Live In: The Reality Of Change. Science Fiction Is The Very Literature Of Change. In Fact, It Is The Only Such Literature We Have.

The Big New Development In My Life Is, When I Turned 80, I Decided I No Longer Have To Do Four Pages A Day. For Me, It's Like Retiring.

You Can't Trust Reason. We Threw It Out Of The Ad Profession Long Ago And Have Never Missed It.
