"Feeling sad, Greta girl, because you'll never understand what's happening to us all," Illy asked me, "because you'll never be anything but a shadow fighting shadows—and trying to love shadows in between the battles? It's time you understood we're not really fighting a war at all, although it looks that way, but going through a kind of evolution, though not exactly the kind Erich had in mind.

"Your Terran thought has a word for it and a theory for it—a theory that recurs on many worlds. It's about the four orders of life: Plants, Animals, Men and Demons. Plants are energy-binders—they can't move through space or time, but they can clutch energy and transform it. Animals are space-binders—they can move through space. Man (Terran or ET, Lunan or non-Lunan) is a time-binder—he has memory.

"Demons are the fourth order of evolution, possibility-binders—they can make all of what might be part of what is, and that is their evolutionary function. Resurrection is like the metamorphosis of a caterpillar into a butterfly: a third-order being breaks out of the chrysalis of its lifeline into fourth-order life. The leap from the ripped cocoon of an unchanging reality is like the first animal's leap when he ceases to be a plant, and the Change World is the core of meaning behind the many myths of immortality.

"All evolution looks like a war at first—octopoids against monopoids, mammals against reptiles. And it has a necessary dialectic: there must be the thesis—we call it Snake—and the antithesis—Spider—before there can be the ultimate synthesis, when all possibilities are fully realized in one ultimate universe. The Change War isn't the blind destruction it seems.

"Remember that the Serpent is your symbol of wisdom and the Spider your sign for patience. The two names are rightly frightening to you, for all high existence is a mixture of horror and delight. And don't be surprised, Greta girl, at the range of my words and thoughts; in a way, I've had a billion years to study Terra and learn her languages and myths.

"Who are the real Spiders and Snakes, meaning who were the first possibility-binders? Who was Adam, Greta girl? Who was Cain? Who were Eve and Lilith?

"In binding all possibility, the Demons also bind the mental with the material. All fourth-order beings live inside and outside all minds, throughout the whole cosmos. Even this Place is, after its fashion, a giant brain: its floor is the brainpan, the boundary of the Void is the cortex of gray matter—yes, even the Major and Minor Maintainers are analogues of the pineal and pituitary glands, which in some form sustain all nervous systems.

"There's the real picture, Greta girl."

The feather-talk faded out and Illy's tendril tips merged into a soft pad on which I fingered, "Thanks, Daddy Longlegs."
