" But how can we be sure that what we’re hearing isn’t our own voice, our own subconscious desires? The message we listen for so carefully must be mediated through our own experience, our personality, our heredity, our inner needs. Can we ever break free of the devices and desires of our own hearts? Might not our conscience be telling us what we most want to hear? "

― P.D. James , Devices and Desires (Adam Dalgliesh #8)
