Best known for his Incompleteness Theorem, Kurt Gödel (1906–1978) is considered one of the most important mathematicians and logicians of the 20th century. By showing that the establishment of a set of axioms encompassing all of mathematics would never succeed, he revolutionized the world of mathematics, logic, and philosophy. Rebecca Goldstein is the author of Incompleteness: The Proof and Paradox of Kurt Gödel and most recently, Betraying Spinoza: The Renegade Jew Who Gave Us Modernity. She is a fellow of the American Academy of Arts and Sciences, and has received many awards for her fiction and scholarship, including a John D. and Catherine T. MacArthur Foundation Fellowship. She shares her insight into the life and work of Kurt Gödel.
