Broca's Brain - Carl Sagan [170]
Those who raise questions about the God hypothesis and the soul hypothesis are by no means all atheists. An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do now to be sure that no such God exists. To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed. A wide range of intermediate positions seems admissible, and considering the enormous emotional energies with which the subject is invested, a questing, courageous and open mind seems to be the essential tool for narrowing the range of our collective ignorance on the subject of the existence of God.
When I give lectures on borderline or pseudo or folk science (along the lines of Chapters 5 through 8 of this book) I am sometimes asked if similar criticism should not be applied to religious doctrine. My answer is, of course, yes. Freedom of religion, one of the rocks upon which the United States was founded, is essential for free inquiry. But it does not carry with it any immunity from criticism or reinterpretation for the religions themselves. The words “question” and “quest” are cognates. Only through inquiry can we discover truth. I do not insist that these connections between religion and perinatal experience are correct or original. Many of them are at least implicit in the ideas of Stanislav Grof and the psychoanalytic school of psychiatry, particularly Otto Rank, Sandor Ferenczi and Sigmund Freud. But they are worth thinking about.
There is, of course, a great deal more to the origin of religion than these simple ideas suggest. I do not propose that theology is physiology entirely. But it would be astonishing, assuming we really can remember our perinatal experiences, if they did not affect in the deepest way our attitudes on birth and death, sex and childhood, on purpose and ethics, on causality and God.
AND COSMOLOGY. Astronomers studying the nature and origin and fate of the universe make elaborate observations, describe the cosmos in differential equations and the tensor calculus, examine the universe from X-rays to radio waves, count the galaxies and determine their motions and distances—and when all is done a choice is to be made between three different views: a Steady State cosmology, blissful and quiet; an Oscillating Universe, in which the universe expands and contracts, painfully and forever; and a Big Bang expanding universe, in which the cosmos is created in a violent event, suffused with radiation (“Let there be light”) and then grows and cools, evolves and becomes quiescent, as we saw in the previous chapter. But these three cosmologies resemble with an awkward, almost embarrassing precision the human perinatal experiences of Grof’s Stages 1, 2, and 3 plus 4, respectively.
It is easy for modern astronomers to make fun of the cosmologies of other cultures—for example, the Dogon idea that the universe was hatched from a cosmic egg (Chapter 6). But in light of the ideas just presented, I intend to be much more circumspect in my attitudes toward folk cosmologies; their anthropocentrism is just a little bit easier to discern than ours. Might the puzzling Babylonian and Biblical references to waters above and below the firmament, which Thomas Aquinas struggled so painfully to reconcile with Aristotelian physics, be merely an amniotic metaphor? Are we incapable of constructing a cosmology that is not some mathematical encrypting of our own personal origins?
Einstein’s equations of general relativity admit a solution in which the universe expands. But Einstein, inexplicably, overlooked
