The human brain forms beliefs. Proofs about beliefs are also a form of “belief” and are not exempt from errors. (Newberg, Andrew, MD., and Mark Robert Waldman. Why We Believe What We Believe. p 20-21. NY:Free Press, 2006.)

When you believe in yourself, brain circuits are open wide, allowing the knowledge and wisdom already there to circulate freely. Emotional channels open wide, allowing you to love and be loved, to enjoy life to the fullest. All your talents are mustered by belief. (Fox, Arnold, MD, and Barry Fox, PhD. Wake Up! You’re Alive! p 54-55. FL: Health Communications, 1988.)
