Midgley also expressed her interest in Paul Davies' ideas on the inherent improbability of the order found in the universe. She argued that "there's some sort of tendency towards the formation of order", including towards life and "perceptive life". The best way, she argued, of talking about this is using the concept of "a life force", although she acknowledged that this is "vague". She also argued that "gratitude" is an important part of the motivation for theism. "You go out on a day like this and you're really grateful. I don't know who to."
