Broca's Brain - Carl Sagan [171]
I do not know how close the analogies are between personal perinatal experiences and particular cosmological models. I suppose it is too much to hope that the originators of the Steady State hypothesis were each born by Caesarean section. But the analogies are very close, and the possible connection between psychiatry and cosmology seems very real. Can it really be that every possible mode of origin and evolution of the universe corresponds to a human perinatal experience? Are we such limited creatures that we are unable to construct a cosmology that differs significantly from one of the perinatal stages?* Is our ability to know the universe hopelessly ensnared and enmired in the experiences of birth and infancy? Are we doomed to recapitulate our origins in a pretense of understanding the universe? Or might the emerging observational evidence gradually force us into an accommodation with and an understanding of that vast and awesome universe in which we float, lost and brave and questing?
It is customary in the world’s religions to describe Earth as our mother and the sky as our father. This is true of Uranus and Gaea in Greek mythology, and also among Native Americans, Africans, Polynesians, indeed most of the peoples of the planet Earth. However, the very point of the perinatal experience is that we leave our mothers. We do it first at birth and then again when we set out into the world by ourselves. As painful as those leave-takings are, they are essential for the continuance of the human species. Might this fact have some bearing on the almost mystical appeal that space flight has, at least for many of us? Is it not a leaving of Mother Earth, the world of our origins, to seek our fortune among the stars? This is precisely the final visual metaphor of the film 2001: A Space Odyssey. Konstantin Tsiolkovsky was a Russian schoolmaster, almost entirely self-educated, who, around the turn of the century, formulated many of the theoretical steps that have since been taken in the development of rocket propulsion and space flight. Tsiolkovsky wrote: “The Earth is the cradle of mankind. But one does not live in the cradle forever.”
We are set irrevocably, I believe, on a path that will take us to the stars—unless in some monstrous capitulation to stupidity and greed, we destroy ourselves first. And out there in the depths of space, it seems very likely that, sooner or later, we will find other intelligent beings. Some of them will be less advanced than we; some, probably most, will be more. Will all the space-faring beings, I wonder, be creatures whose births are painful? The beings more advanced than we will have capabilities far beyond our understanding. In some very real sense they will appear to us as godlike. There will be a great deal of growing up required of the infant human species. Perhaps our descendants in those remote times will look back on us, on the long and wandering journey the human race will have taken from its dimly remembered origins on the distant planet Earth, and recollect our personal and collective histories, our romance with science and religion, with clarity and understanding and love.
* It is interesting to wonder why psychedelic molecules exist—especially in great abundance—in a variety of plants. The psychedelics are unlikely to provide any immediate benefit for the plant. The hemp plant probably does not get high from its complement of 1Δ tetrahydrocannabinol. But human beings cultivate hemp because the hallucinogenic properties of marijuana are widely prized. There is evidence that in some cultures
