" Religion is the emulation of the adult by the child. Religion is the encystment of past beliefs: mythology, which is guesswork, the hidden assumptions of trust in the universe, those pronouncements which men have made in search of personal power, all of it mingled with shreds of enlightenment. And always the ultimate unspoken commandment is ‘Thou shalt not question! "

― Frank Herbert , Children of Dune (Dune, #3)
