This is not Ferris' best book. It's a loose collection of his thoughts about consciousness in a cosmic context, and I don't know what that really means.
If there's consciousness out there, it most likely is not like ours, at all, Ferris argues. If there are aliens with consciousness, the author fears that they will "bludgeon us into a dog's life or into extinction." There's a good Demon image here and the reference to a "dog's life" is about its subservience as opposed to being wild and free - as if humans are, what, free from myth and illusion, conformity and our own alphas, and fakery and manipulation?
Ferris explains mystic consciousness (unity) in terms of the "internal architecture of the brain" and its "integration program - that is responsible for presenting the multipartite functions of the brain to the conscious mind as a unified whole." But if we push too hard, he writes, "the result might be direct exposure to the cacophonous voices of many inharmonious programs, speaking in a wild diversity of codes for which we have as yet no translation - and that hazardous voyage might well rob any but the most adept explorer of his sense of a coherent self and a coherent universe. Here lies the territory of divine madness...." I liked that.
Referring to Darwin, Ferris writes that "Random genetic mutation creates unique individuals within each species; natural selection sometimes favors the survival prospects of these atypical individuals" who go on to form new species traits. That's a standard understanding but what Ferris is not saying is that before everyone acquires such traits, we are "unique individuals" with variations in our inborn dispositions and will remain such so long as these tendencies and traits are not harmful to survival, prior to reproduction. In other words, there's room for an in-born biological character within each of us.
Toward the end, Ferris notes some interesting studies suggesting that catastophes hit the earth every 26 million years, wiping out species galore. At that point, there's a good chance that earthly consciousness goes dark, leaving consciousness to aliens, if they exist.
