Mesmerizing. As this vibrant biography so beautifully elucidates, the truth of a life can't ever be proven; it can only be shown.--Jennifer Szalai, New York Times Book Review [Budiansky] writes vividly, and the book overflows with fascinating detail. Enthralling.--David Edmonds, Wall Street Journal Wonderfully engrossing.--Adam Gopnik, The New Yorker Journey to the Edge of Reason is an intimate and haunting portrait of one of the most elusive gods on Princeton's Mt. Olympus. A triumph of research and a wonderful read.

--Sylvia Nasar, author of A Beautiful Mind Kurt Gödel's mathematical results on incompleteness and undecidable propositions leave it up to us, as individuals, to choose whether to mourn these limits to the power of formal systems, or celebrate his proof that even the most rigid numerical bureaucracy contains the tools by which higher truth will always be able to effect an escape. Stephen Budiansky's Journey to the Edge of Reason expertly and humanely frames these results between Gödel's childhood under the dark shadow of the Austrian and Nazi bureaucracies, his escape to America, his descent into physical and mental illness, and his achievement of a reconciliation between spiritual faith and scientific proof.--George Dyson, author of Analogia and Turing's Cathedral Expansive . places [Gödel's] achievements in their social and political context.--The New Yorker A painstakingly researched and lucidly presented biography--a close-up of one of the most influential and enigmatic thinkers of the twentieth century--full of vivid detail and sharp historical insight.--Karl Sigmund, professor of mathematics, University of Vienna, and author of Exact Thinking in Demented Times A brilliant biography of one of the most original thinkers of all time, Journey to the Edge of Reason is as deep and precise as the genius it describes. In a paradox befitting Gödel himself, it takes a tale of logic and its limits and finds, at its heart, something strangely soulful and sympathetic.--Steven Strogatz, professor of mathematics, Cornell University, and author of Infinite Powers Terrific.

An outstanding biography of a man of incomprehensible brilliance.--Kirkus, starred review Gödel comes through as a brilliant though tragic figure in Budiansky's richly descriptive prose. This captivating portrait of a great if neurotic mind hits the mark.--Publishers Weekly, starred review Budiansky exposes the social and political influences that shaped thelife of this brilliant Austrian mathematician. But Budiansky's greateraccomplishment is that of penetrating a mind that reoriented the entiremathematical world. A portrait remarkable for both its intellectual depthand for its compassion.--Booklist, starred review Remarkable. A singular virtue of this well-researched andwell-written book is that Budiansky takes his subject's life as seriously ashis mathematical work.

Readers shouldn't be discouraged by the complexityof Go¨del's mathematics; this is the first major biography of the brilliant yettragic figure and, in all respects, a first-rate one.--Library Journal, starred review.
