A Voyage to Arcturus is a novel by the English writer David Lindsay, first published in 1920. It combines fantasy, philosophy, and science fiction in an exploration of the nature of good and evil and their relationship with existence. Described by critic and philosopher Colin Wilson as the "greatest novel of the twentieth century", it was a central influence on C. S. Lewis' Space Trilogy, and through him on J. R. R. Tolkien, who said he read the book "with avidity". Clive Barker called it "a masterpiece" and "an extraordinary work ... quite magnificent."
