The text in the poster below is not of my creation. Most of the poster is an extended quote by John Lilly. Lilly used the same concept in different places with slightly different wording. I am not sure exactly where this particular quote was lifted from. At the top of the right column are two versions of the Mentat's Creed. The upper quote is by Frank Herbert taken from his book, Dune. Below that is a Reformulation of the Mentat's Creed done by Marik, aka Mark Defrates.
