"Believing in God is a leap of faith. As such, William of Occam can kiss my grit."
"This is fine, but
why do you have this article of faith? What psychological need does it fulfill? What value(s) does it uphold? For instance, I have "faith" in an objective reality because its existence is necessary for technological
progress. In turn, technological progress aimed at the enhancement of Being provides my life with a purpose.
Everything boils down to values, and values are determined by Will. What is Will determined by?
