Author, Greg Heard explores humankind's need to find meaning through the worlds of science, religion and psychology; each field proclaiming proof in their hypotheses. He provides an interesting argument that human beings can only function in a reality they consensually agree to be real, and therefore, hold steadfast to certain beliefs that are staunchly defended: "I have proof " He draws from an impressive repertoire of great thinkers in recent history: Jung, Kepler, Koestler and many more to support his narrative that no one can definitively claim proof.
