This definitive biography of the logician and philosopher Kurt Gödel, now available in paperback, is the first in-depth account to integrate details of his personal life with his work. Based on the author's intensive study of Gödel's papers and surviving correspondence, Dawson examines the life of this driven man, whose work on the foundations of mathematics has fundamentally changed our thoughts on the subject and has stimulated much of the research conducted in the twentieth century. He further explores the relationship between Gödel's personality and his scientific achievements and describes the impact that Gödel's results have had on our modern world view.
