The album takes its title from a quote often attributed to Hassan-i-Sabbah: "Nothing is true, everything is permitted". When it comes to how this quote relates to the album's concept, Turner is again reluctant to reveal too much. "I'll just say that much of working on this record, for me, was about the power and nature of perception, and the ways in which it affects our behavior and the way we see the world," he says. "I'll just leave it at that, and people can draw their own conclusions."
