The Pawns of Null-A
 The Pawns of Null-A usually written The Pawns of Ā is a 1956 science fiction novel by A. E. van Vogt originally published as a four-part serial in Astounding Stories from October 1948 to January 1949 (this leads to the mistaken idea that the book was published in 1948 due to the copyright notice). It incorporates concepts from the General semantics of Alfred Korzybski and refers to non-Aristotelian logic. It was published in the UK under the name The Players of Null-A.
