The Pawns of Null-A is a 1956 science fiction novel by American-Canadian writer A. E. van Vogt, originally published as a four-part serial in Astounding Stories from October 1948 to January 1949 as The Players of Null-A. It incorporates concepts from the General semantics of Alfred Korzybski and refers to non-Aristotelian logic. It was published in the UK with the original name and in later US republication also had the original name restored.
The novel is a continuation of the story of Gilbert Gosseyn from The World of Null-A, expanding on the galactic events which drove the interplanetary invasion of the earlier story.
