Hao Wang (1921-1995) was once one of many few confidants of the good mathematician and philosopher Kurt Gödel. A Logical Journey is a continuation of Wang's Reflections on Gödel and likewise elaborates on discussions contained in From arithmetic to Philosophy. A decade in guidance, it comprises vital and surprising insights into Gödel's perspectives on a variety of concerns, from Platonism and the character of good judgment, to minds and machines, the life of God, and positivism and phenomenology.

The influence of Gödel's theorem on twentieth-century concept is on par with that of Einstein's idea of relativity, Heisenberg's uncertainty precept, or Keynesian economics. those formerly unpublished intimate and casual conversations, notwithstanding, carry to mild and magnify Gödel's different significant contributions to common sense and philosophy. They display that there's even more in Gödel's philosophy of arithmetic than is usually believed, and extra in his philosophy than his philosophy of mathematics.

Wang writes that "it is even attainable that his fairly casual and loosely based conversations with me, which i'm freely utilizing during this publication, will change into the fullest latest expression of the varied elements of his inadequately articulated normal philosophy."

The first chapters are dedicated to Gödel's existence and psychological improvement. within the chapters that keep on with, Wang illustrates the search for overarching strategies and grand unifications of data and motion in Gödel's written speculations on God and an afterlife. He provides the history and a chronological precis of the conversations, considers Gödel's reviews on philosophies and philosophers (his aid of Husserl's phenomenology and his digressions on Kant and Wittgenstein), and his try to display the prevalence of the mind's energy over brains and machines. 3 chapters are tied jointly via what Wang perceives to be Gödel's governing excellent of philosophy: an actual thought within which arithmetic and Newtonian physics function a version for philosophy or metaphysics. eventually, in an epilog Wang sketches his personal method of philosophy unlike his interpretation of Gödel's outlook.
