Beliefs should be like fluid entities within the mind, some malleable and doubtful, others more viscous and certain. But feeling certain should never be confused with being incontestable. Once a belief is allowed to solidify, it becomes like a shackle on the mind, inhibiting exploration, learning and growth. A fluid mind should never allow a belief to be so hardened that it is beyond rational scrutiny. A fluid mind always invites rational examination upon even its most cherished convictions.
“What our society really needs is not more religion but a richer notion of the nature of morality.”
—Theodore Schick, Jr.
