"Perhaps existence isn't something that gets bestowed from the outside, by having "fire breathed" into a potentiality by some unexplained fire-breathing agency (that is, a transcendent existence generator) but is ...something self-activating. I have suggested that only self-consistent loops capable of understanding themselves can create themselves, so that only universes with (at least the potential for) life and mind really exist."
