Excerpts from “Challenges Facing Science and Religion”
In the Vaishnava tradition of India, God is defined
as Brahman, Paramatma, and Bhagavan: the unlimited light of pure being
underlying nature, the Lord within the heart, and the supreme transcendental
Person. In Christian tradition, a similar idea can be found in the Trinity
of Father, Son, and Holy Spirit. In both traditions the emphasis is on
God’s personal nature. As a transcendental person, God controls nature
on a grand scale, He acts within history, and He deals with people on an
individual level.
This concept of God has been central to the lives of
large numbers of people over many centuries, but at the present time it
is not intellectually respectable. To be sure, it is often said that there
is no conflict between science and religion. But this statement is true
only if one makes a drastic redefinition of traditional concepts of God.
Consider the following conversation, which took place
in 1959, between astronomer Harlow Shapley and biologist Julian Huxley:
Shapley: And in that famous address in 1951 the Pope went along
with evolution.
Huxley: He still said there must be a God who is somehow responsible
in some way, didn’t he?
Shapley: Well, he didn’t deny God, no. And you don’t either.
Huxley: I certainly do.
Shapley: Oh, no. If you defined God, you wouldn’t.
Huxley: Now don’t go into semantics.
Shapley: You’re not an atheist, Julian; you’re an agnostic.
Huxley: I am an atheist, in the only correct sense, that I don’t
believe in a supernatural being who influences natural events.
The success of modern science depends on our ability
to create mechanistic models of natural phenomena in which all natural
causes are represented by formulas and numbers. Since God cannot be reduced
to formulas, God has to be decoupled from nature. At most, God can be admitted
as the ultimate cause of the laws used in scientific models. As physicist
Steven Weinberg put it, “The only way that any sort of science can proceed
is to assume that there is no divine intervention and see how far one can
get with this assumption.”
The elimination of God from nature begins with the rejection
of stories that seem obviously contrary to natural laws—stories about the
lifting of mountains (Krishna) or the parting of seas (Jehovah). At first,
this elimination can be seen as a rational reform in which the dross of
superstition is removed and the way is paved for a deeper spiritual understanding.
An attractive approach is to make a distinction between the rational and
the transcendental. One treats the rational domain according to the methods
and findings of science, while positing a transcendental domain lying beyond
reason and accessible only to higher, spiritual states of consciousness.
The transcendental domain can be approached only through faith, acceptance
of revealed knowledge, and submissive obedience to higher spiritual authority.
This approach to religion and science can be a useful
rhetorical strategy, and it may be satisfactory for a rare person who truly
lives on a high transcendental platform and directly knows what is transcendental.
But for others, it suffers from the difficulty that it is hard to make
a clear distinction between the rational and transcendental domains. How
do we draw the line?
If we hold the line at a particular part of the intellectual
landscape, we will come in conflict with science, which will insist on
extending its established theoretical picture. If we let the line be completely
flexible, we will find that nothing relevant to the world of our experience
remains on the transcendental side. This lends weight to the perspective
that the transcendental is strictly anirvacanéyam, having no impact
whatsoever on our words or our actions. But this is a far cry from traditional
conceptions of God as a supreme personality (with both describable and
indescribable aspects) who takes an interest in individual lives.
On surveying the issues involving science and religion,
my overwhelming impression is that there is much that we do not know. I
therefore think that it is premature to try to draw a clear-cut line between
science and religion. Rather, we should realize that there is a broad gray
area in which much further exploration needs to be done.
In the theoretical domains claimed by science, many fundamental
questions remain. In the empirical study of nature, and especially in the
study of human life, much data begs for an explanation and has not been
assimilated into the scientific world view. In the field of religion there
are likewise many unanswered questions.
I will briefly discuss some important issues involving
science and religion, and point out questions that need to be addressed.
God and the Laws of Physics
Sir Isaac Newton is a good starting point. Newton’s great contribution
was to introduce a system of mathematical laws that could be verified with
quantitative precision. In so doing, he created a domain of natural law
that inevitably came into territorial conflict with the domain of divine
action. . . .
A set of deterministic differential equations define
the motion of material particles. Even if something is thought to exist
outside the collection of material particles, there appears to be no way
for it to influence their motion, and Newton’s famous divine adjustments
therefore appear awkward and unnatural.
But the key word here is “appears.” In recent years it
has been discovered that in many situations, Newton’s equations give rise
to a phenomenon known as deterministic chaos. This means that arbitrarily
small changes in the motion of Newtonian particles are quickly amplified
to produce large changes. It doesn’t matter how small the changes are.
If you make the changes a millionth as large or a millionmillionth as large,
they quickly amplify to produce big effects.
It has also been discovered that deterministic chaos
gives engineers a practical opportunity to systematically control chaotic
systems by making tiny adjustments. The implication is that God could readily
control nature by introducing adjustments far smaller than anything we
could ever hope to measure. Could this be a way for God to exercise divine
control over a semi-autonomous natural world?
The Special Theory of Relativity
Early in the twentieth century, Albert Einstein introduced fundamental
changes into classical, Newtonian physics with his celebrated special theory
of relativity. This theory yields the famous formula E= mc2,
which was demonstrated by the release of atomic energy. But apart from
this, relativity theory has few practical consequences, since it predicts
measurable effects differing from classical physics only for objects with
velocities approaching the speed of light. But Einstein’s theory has profound
philosophical implications. In the equations called Lorentz transformations,
it allows time to be mapped into space and space to be mapped into time.
This means that time and space must have the same geometric nature. Time,
including past, present, and future, must exist as an extended continuum,
just as space does. All events have their place in this continuum, and
the passage of time is an illusion. . . .
What is it that experiences the illusion? If all events
are just blips in an existing continuum, what room is there for an experiencer
who moves through events in temporal order? . . . .
Quantum Physics
Quantum physics constitutes a great departure from the deterministic
theories of classical physics and relativity. As such, it has sometimes
been heralded as the gateway to a new synthesis of science and religion
that will reintroduce spirit and consciousness into the world of matter.
But this turns out to be easier said than done. . . .
The lesson of quantum mechanics seems to be that we must
either discard the idea that spirit influences matter or be prepared to
develop a new physics that includes some kind of spirit-matter interface.
The latter program is far from easy to carry out, but we may find many
rewarding insights if we make the attempt.
The Brain and Consciousness
In the scientific world, the theories of physics provide
the basis for the life sciences and for our understanding of mind and consciousness.
Thus Nobel laureate Francis Crick has recently announced what he calls
the Astonishing Hypothesis. He claims, “You, your joys and your sorrows,
your memories and your ambitions, your sense of personal identity and free
will, are in fact no more than the behavior of a vast assembly of nerve
cells and their associated molecules.”
In one sense, this should be called the Standard Hypothesis.
With a few exceptions, such as Sir John Eccles, neuroscientists take it
for granted that mind and consciousness can be fully understood in terms
of physical brain processes.
Yet contemporary brain research does have an astonishing
feature. Thus far, no one has been able to even suggest an intelligible
connection between physiochemical processes and the qualities of perception
(called “qualia”) that make up conscious experience. Thus Crick admits,
“I have said almost nothing about qualia—the redness of red—except to brush
it to one side and hope for the best.” . . .
Life after Death
In the Bhagavad-gita, Krishna refers to the
body as a machine occupied by the soul and guided by the Lord in the heart.
In contrast, both modern science and some schools of Christian thought
have embraced the idea of the living being as a pure machine. Physicists
such as John Polkinghorne propose that the self survives death through
a process of physical reconstruction. Thus Polkinghorne says of the atoms
that make up our bodies: “It is the pattern that they form which constitutes
the physical expression of our continuing personality. There seems to be
no difficulty in conceiving of that pattern, dissolved at death, being
recreated in another environment in an act of resurrection.”
By implicitly accepting Crick’s astonishing hypothesis,
Polkinghorne is able to suggest a scientific model of the Christian doctrine
of resurrection. But if conscious self identity is distinct from the brain,
as I proposed above, then survival after death must involve more than just
the pattern of atoms in the body. The Bhagavad-gita, of course,
presents the idea of transmigration, in which the personality is carried
by the soul and subtle mind from one body to another.
It is remarkable that there is a great deal of empirical
evidence suggesting that transmigration may actually take place. The psychiatrist
Ian Stevenson has studied thousands of cases in which a young child seems
to spontaneously remember a previous life, without having had the opportunity
to learn about that life by ordinary means of communication. Stevenson
has shown that skills, interests, phobias, and other personality traits
tend to show continuity from one life to another. He has also studied cases
in which children have birthmarks corresponding to wounds causing death
in their previous life. . . .
Near Death Experiences
NDEs provide another example of empirical evidence
pertaining to the possible survival of the conscious self after death.
NDEs are generally reported in connection with life-threatening physical
traumas such as heart attacks, but they also resemble the spontaneous socalled
mystical visions of people in a normal state of health. In addition, shamans,
yogis, and mystics in many traditions have sought to deliberately separate
the perceiving self from the body and travel in an out-of-body state.
Typical NDEs involve an autoscopic and a transcendental
phase. In the autoscopic phase, the subject sees his or her body from outside
the body. In this phase, the person may remember seeing things that should
have been invisible to the body’s physical eyes, and this may be interpreted
as evidence of a non-ordinary state of consciousness.
In the transcendental phase, the subject often reports
entering into another world, typically characterized by brilliant light,
beautiful scenery, and a sense of universal knowledge. The subject may
encounter other persons, ranging from effulgent religious figures to departed
relatives. . . .
Extraordinary Events
Religious traditions in both India and the West are filled with stories of extraordinary encounters between humans and various kinds of beings, ranging from angels, demigods, and avatars to demons and evil spirits. Today, of course, it is customary to consign these stories to the mythological side of religion, since we know that such beings do not exist. We tend to assume, on the most charitable level, that such stories may have been created for the sake of conveying moral and spiritual lessons to a community of naive believers with an appetite for tall tales. But the concept of God as a historical actor in Judeo-Christian tradition (Jehovah) and in Vaishnava tradition (Krishna) depends on the truth of extraordinary stories. If we relegate all of these stories to fantasy and myth, then the role of God in these traditions is drastically changed. . . .
The Fossil Record
We now turn from the discussion of present-day phenomena to the historical
sciences, such as geology and evolutionary biology. It is here that some
of the greatest conflicts have taken place between science and religion.
In the early nineteenth century, the developing science
of geology began to reveal a very strange picture of the history of life
on the earth. In its current form, the story begins with the formation
of the earth about 4.5 billion years ago. After less than a billion years,
life appeared in the form of bacteria and algae. This state of affairs
persisted until about 500 to 600 million years ago, with the appearance
of peculiar marine life forms, such as the Ediacara fauna and the creatures
of the Burgess Shale. A wide variety of more familiar marine creatures
appeared in the subsequent Cambrian period, and life began to seriously
invade the land in the Devonian, about 400 million years ago. There followed
the age of Carboniferous coal swamps, the age of early reptiles, and then
some 150 million years of dinosaurs. After the dinosaurs mysteriously died
out, the age of mammals prevailed for some 65 million years up to the present.
Humans of modern form appeared at the very end of this period, no more
than about 100,000 years ago.
This story does not explicitly appear in the sacred books
of any religion, as far as I am aware. Some Christian creationists deny
it altogether and advocate a young earth, based on Mosaic chronology, which
dates the creation of the earth to about 6,000 to 10,000 years ago. Other
creationists prefer to reconcile the Bible with geology by interpreting
the days of creation in Genesis as long ages. And some propose the existence
of races of humans or semi-humans that preceded the recent appearance of
Adam and Eve.
In Hinduism, the immensity of geological time does not
pose a problem. Hindu chronology, as defined in the Puranas, is
based on several major time intervals similar to those of the geologists.
These are the divya yuga of 4,320,000 years, the manvantara of about
307 million years, and the kalpa of 4,320,000,000 years. Astronomer
Carl Sagan remarked, “The Hindu religion is the only one of the world’s
great faiths . . . in which the time scales correspond, no doubt by accident,
to those of modern scientific cosmology.” . . .
Darwin’s Theory
Scientists interpret the fossil record as the history
of the gradual development of life according to the neo-Darwinian theory
of evolution. I will refer to this briefly as Darwin’s theory, but it was
actually developed after the second World War as a synthesis of Mendelian
genetics and Darwin’s original ideas.
Darwin’s theory is based entirely on the laws of physics
and blind chance. In the words of Darwinian theorist Richard Dawkins, it
attributes the origin of living species to a “blind watchmaker,” completely
devoid of intelligence, foresight, or purpose. For this reason, it has
been strongly rejected by many conservative Christians, who take it that
life was created by Divine Providence.
But other Christian groups, such as the Roman Catholics
and the liberal Protestants, profess to find no difficulty in seeing Darwinian
evolution as God’s method of creation. Some say that God is a strict Darwinian
who simply stood by transcendentally and let evolution produce worshipers
in the fullness of time. Others compromise by proposing guided evolution,
in which God gently nudges the Darwinian process in the desired direction.
This, of course, is not accepted by mainstream science.
In principle, there is no reason why Darwinian evolution
could not be God’s method of creating species. In practice, however, the
theory of evolution itself throws up obstacles against this. Among all
of today’s scientific theories, the neo-Darwinian theory of evolution is
perhaps the easiest to criticize from a theoretical scientific point of
view.
From its very inception, Darwin’s theory has not been
able to explain in detail how complex organs such as brains or eyes come
into being. The general idea is that organs develop by a series of tiny
steps. For example, the eye is said to begin as a light-sensitive spot.
The spot turns into a pit and thus develops directional sensitivity through
shadowing. The pit closes over to form a pinhole camera, and then translucent
skin forms a crude lens that collects and focuses light. Gradually, features
and improvements are added, until we have the eye of an eagle.
The problem is that this is simply a “just so” story
that we are asked to accept on faith. It cannot be verified as we verify
Newton’s theory by calculating a planetary orbit and then observing that
the planet actually follows the orbit. The eye is simply too complex, and
the more we study it, the more complex we find it to be. . . .
Conclusion
Although traditions of personal theism are ruled out
by the spirit of modern science, they are not refuted decisively by the
still-evolving theories of physics. Indeed, even some of the extraordinary
phenomena connected with theistic teachings may eventually find confirmation
as physical and biological sciences come to grips with perplexing forms
of human experience. This may provide the key to understanding how matter
interacts with consciousness.
These developments may take a great deal of time. At
present, our ignorance is overwhelming, but this is a hopeful sign, since
the expansion of knowledge also expands the boundary between the known
and the unknown. The main danger we should avoid is to block the advancement
of knowledge by prematurely imposing final conclusions, either from the
side of scientific rationalism or from the side of religious dogmatism.
