Morton 76: "a species [is] shadowed by an X-species"
77: "You can't be a lifeform unless you have this spectral double, this mutant shadow. Being alive means being supernatural."
"a species is haunted by its X-species in order to exist at all"
"It isn't that frogs and humans and cyanobacteria are not really real, while some underlying flow of 'life' is. There are frogs and they aren't octopuses; they are irreducible. But there are only frogs on condition that every frog has, as its shadow, its X-frog doppelganger"
