The classic novel of non-Aristotelian logic and the coming race of supermen
Grandmaster A. E. van Vogt was one of the giants of the 1940s, the Golden Age of classic SF. Of his masterpieces, The World of Null-A is his most famous and most influential. It was the first major trade SF hardcover ever, in 1949, and has been in print in various editions ever since. The entire careers of Philip K. Dick, Keith Laumer, Alfred Bester, Charles Harness, and Philip Jose Farmer were created or influenced by The World of Null-A, and so it is required reading for anyone who wishes to know the canon of SF classics.
It is the year 2650 and Earth has become a world of non-Aristotelianism, or Null-A. This is the story of Gilbert Gosseyn, who lives in that future world where the Games Machine, made up of twenty-five thousand electronic brains, sets the course of people's lives. Gosseyn isn't even sure of his own identity, but realizes he has some remarkable abilities and sets out to use them to discover who has made him a pawn in an interstellar plot.

A.E. van Vogt's profile page

A. E. Van Vogt was a SFWA Grand Master. He was born in Canada and moved to the U.S. in 1944, by which time he was well-established as one of John W. Campbell's stable of writers for Astounding Science-Fiction. He lived in Los Angeles, California and died in 2000.

“A. E. Van Vogt's early stories broke like claps of thunder through the science fiction field. Such novels as Slan, The Weapon Shops of Isher, and The World of Null-A, all were written with invention, dramatic impact, and a sense of breathless wonder that won him instant popularity” —Jack Williamson
“After more than half a century I can still recall the impact of his early stories.” —Arthur C. Clarke
“Interplanetary skullduggery in the year 2650. Gilbert Gosseyn has a pretty startling time of it before he gets to the root of things. Fine for addicts of science-fiction” —The New Yorker
“One of those once-in-a-decade classics” —John W. Campbell
“A. E. van Vogt was one of the first genre writers ever to publish an actual science fiction book, at a time when science fiction as a commercial publishing category did not yet exist, and almost all SF writers--even later giants such as Robert A. Heinlein--were able to publish novels only as serials in science fiction magazines. It's indicative of the prestige and popularity that van Vogt could claim at the time that he was one of the first authors to whom publishers would turn when taking the first tentative steps toward establishing science fiction as a viable publishing category. . . . Nobody, possibly with the exception of the Bester of The Stars My Destination, ever claim close to matching van Vogt for headlong, breakneck pacing, or for the electric, crackling paranoid tension with which he was capable of suffusing his work.” —Gardner Dozois
