The show’s creators adapted this from an older idea that primitive man interpreted his thoughts as the voice of god. In the show’s fiction, the important thing to remember is that the host hears Arnold’s voice whispering to them. Describing the Bicameral Mind, Ford recalls, “He wanted to create consciousness. See, Arnold built a version of their cognition in which the hosts heard their programming as an inner monologue. As a way to bootstrap consciousness. The hosts malfunctions were colorful. ”
This is a wonderfully complex rabbit hole that you can dive down in order to receive some fundamental understanding of how one of the core concepts of WestWord works. It was primarily pioneered by Julian Jaynes, who wrote the book “The Origin of Consciousness in the Breakdown of the Bicameral Mind” … this book mentions reveries on the very first page.
From which, another redditor pulled this:
“It all began in what seemed in my personal narritizations as an individual choice of a problem with which I have had an intense involvement for most of my life: the problem of the nature and origin of all this invisible country of touchless rememberings and unshowable reveries, this introcosm that is more myself than anything I can find in any mirror.
