(This continues the post on the natural knowledge of God. And, once again, I can provide real, live footnotes on request.)
The
theme of the natural knowledge of God has made its way into subsequent
Christian reflection. As Augustine wrote early in the fifth century in his
beautiful opening prayer to Confessions
(1.2), “Lord, you have made us for yourself, and our hearts are restless until
they rest in you.” This is of course a prayer and therefore occurs within
faith—it is not therefore technically a proof—and in it Augustine gives our
natural yearning for God both an existential and creational caste.
More
philosophically, the great thirteenth century Roman Catholic theologian, Thomas
Aquinas (who thus wrote before the Protestant/Catholic divide), offered an
initial outline of the famous “Five Ways.” First, there is the Argument from Motion: since everything
that moves is moved by another, there must thereby exist an Unmoved Mover.
Second, the Argument from Efficient Cause:
the sequence of causes that make up this universe must have a First Cause.
Third, the Argument to Necessary Being: since
all things that exist are dependent on other things for their existence, there
must exist at least one thing that is not dependent. This then is a Necessary
Being. Four, the Argument from Gradation:
Since all things that exist can be compared to such qualities as degrees of
goodness, there must exist something that is an Absolutely Good Being. Finally,
the Teleological Argument: The
intricate design and order of existent things and natural processes imply that
a Great Designer exists. Whether or not these Five Ways are maligned or
praised, they have offered an excellent outline for subsequent thinkers who
make philosophical arguments for God’s existence and for our natural knowledge
of God. In fact, they really constitute a summary of what would have been known
to his students reading the Summa and
therefore not a full-blown proof. Thomas bases the Five Ways on the conviction
that human beings have knowledge that
God exists, although revelation is needed to know who God is (Summa 1.2.3).
In
the seventeenth century—right at the flowering of modern science—the mathematician
Blaise Pascal offered another proof for God. He began, in a similar vein to
Augustine with our existential search for rest: “By nature, we all seek
happiness.” But where do we seek it? “Some seek the good in authority, some in
intellectual inquiry and knowledge, some in pleasure.” Pascal, in his Pensées, continued by observing that all
these various potential sources for happiness, for a beautiful life, leave us
craving for more. He pondered what that meant:
What else does this craving, proclaim but that there was once in man a true happiness, of which all that now remains is the empty print and trace? This he tries in vain to fill with everything around him… since this infinite abyss can be filled only with an infinite and immutable object; in other words by God himself.
C. S. Lewis, in Mere Christianity (and several other places), echoed this
conclusion about three hundred years after Pascal with a simple, logically
compelling, phrase in his apologetics: “If
I find in myself desires which nothing in this world can satisfy, the only
logical explanation is that I was made for another world.” Lewis believed that
this argument from desire constitute one of the strongest proofs for God’s
existence.
It
may surprise some in the Reformed tradition—at least those who have read Karl
Barth’s cavils against “natural theology”—that the seminal voice of Reformed
theology, John Calvin, wrote similarly of the “awareness of divinity.” Calvin
was not out to prove God, but to state that inherent in human existence is a
basic, vague, and powerful natural knowledge of God. Indeed, in Calvin’s vastly
influential 1559 Institutes of the
Christian Religion (1.3.1), he wrote, “There is within the human mind, and
indeed by natural instinct, an awareness of divinity.” This awareness of
divinity or sensus divinitatis is
“beyond dispute” according to Calvin. It is the formulation of the natural
knowledge of God that I follow in this chapter. (This may be what the Roman
Catholic theological giant, Karl Rahner, is after in his transcendental
“openness to being,” but I find his reflections too tinged with Kantian notions
to be sufficiently biblical or convincing.)
One
final note here: I am recounting these voices not as proofs for God’s existence (though some certainly presented them as
such), but as signs or witnesses to
the God the Church confesses as Maker of heaven and earth. They may in fact
work as proofs, but that is not my focus; instead I am arguing that the
doctrine of creation—that God created this world and us as part of it—implies
that we will have a natural knowledge of God. It is not that we see this
natural knowledge and therefore God exists. Instead, when we see that the world
as created by God, we realize that this sensus
divinitatis exists in all people.
For
a scientifically informed systematic theology, one promising nexus for the
natural knowledge of God is the perception of beauty. (Incidentally, I am not
making a proof for God’s existence from the existence of beauty although many
excellent Christian thinkers have done so. Consider Augustine’s argument in City of God XI.4, “The world itself, by
its well-ordered changes and movements, and by the fair appearance of all
visible things, bears a testimony of its own, both that it has been created,
and also that it could not have been created save by God, whose greatness and
beauty are unutterable and invisible.”)
Through creation, human beings
experience beauty. As Gerald Manley Hopkins, the profound nineteenth century
poet intones in “The Golden Echo”: “Give beauty back, beauty, beauty, beauty, back
to God, beauty’s self and beauty’s giver.” The Psalmist declares desires God’s
beauty, “One thing I asked of the Lord, that will I seek after: to live in the
house of the Lord all the days of my life, to behold the beauty of the Lord,
and to inquire in his temple” (Psalm 27:4).
What is beauty? According to the
ancient tradition, beauty is a transcendental—like goodness, unity, and
truth—all of which are thereby indefinable. Plato offers three markers for
beauty, not exactly a definition: order, symmetry, and proportion; Thomas
Aquinas, highlighted integrity, consonance, and clarity (integritas, harmonia, claritas). Beauty arises for both theologians
and scientists through rightly grasping and theorizing about their objects of
study. Beauty thus leads to truth, and beauty provides a lure for study. In
this sense, it is telic, that is, leading
human beings toward a preferred future. For theologians, it means grasping
God’s true nature, God’s creation, and our ethical life. For scientists, it is
rightly perceiving, and theorizing about, nature. When this perception is made
there is discovery, which is accompanied by a sense of completeness. In these
and other ways, beauty represents a common value for scientists and theologians.
(These themes are echoed in the Catholic voice of Hans Urs von Balthasar,
specifically through his magisterial The
Glory of the Lord: A Theological Aesthetics. I cannot overestimate
Balthasar’s contributions to a theological aesthetics, and my debt to his
theological aesthetics is substantial.)
One
of the most important, and underappreciated voices on the importance of beauty
for theology is Jonathan Edwards. (For example, in Balthasar’s seven volumes, I
cannot find a single line on Edwards.) Beauty captivated this eighteenth
century theologian and philosopher—the beauty of the natural world, of God, and
of life lived to God’s glory. Edwards spoke of a particular early experience
where contemplation led him “into a kind of vision… of being alone in the
mountains, or some solitary wilderness, far from all mankind, sweetly
conversing with Christ, and wrapped and swallowed up in God.” Steeped
in the observation of nature that marked the exuberant scientific explosion
following Newton’s impressive discoveries and seminal theories, Edwards gloried
in the beauty of nature. It is worth noting Puritan pastors, as some of the
most educated members of their day, regularly found numerous causes for
reflection on God, nature, and their relationship through “natural philosophy.”
They quite naturally engaged in what today we call “theology and science.”
Edwards’s
natural beauty “consists of a very
complicated harmony; and all the motions and tendencies and figures of bodies
in the universe are done according to proportion,
and therein lies their beauty” (in “The Mind,” emphasis mine). The echoes of
the classical tradition of beauty as proportio
are unmistakable. He also underscored the importance of God’s work as Creator
of this cosmos:
For as God is infinitely the greatest being, so he is allowed to be infinitely the most beautiful and excellent: and all the beauty to be found throughout the whole creation is but the reflection of the diffused beams of that Being who hath an infinite fullness of brightness and glory.
In his philosophical-theological
writings, Edwards maintained a lifelong “preoccupation with beauty, excellence,
and the goodness of creation,” as John E. Smith, Harry S. Stout, and Kenneth P.
Minkem comment in the Edwards Reader.
Finding beauty is at the core of his definition of the spiritual life. To be
fully alive as a human being is to be drawn into Beauty. Beauty in nature
evokes a deeper praise for the Source of beauty. In this way, creation leads
back to the Creator. (For example, Edwards also linked the beauty of God and
the beauty of creation with the beauty of our ethical life, a theme worth
developing separately, although not sufficiently related to the topic at hand.)
What
do natural scientists say? Remarkably, in reading some scientists’ descriptions
of their own work, I have discovered a remarkable similarity with theology,
such that I could transpose words between theology and science and the
statements would sound nearly identical. The beauty of scientific work is to
understand nature rightly and the way it fits together. This common value
provides a stimulating locus for collaboration of theology and science. Beauty
lures us to truth—both in that its innate pleasure motivates human beings to
discover truth and that beauty and truth conform to one another. As Thomas
Aquinas wrote, “The supreme beauty of human nature consists in the splendor of
knowledge.” Beauty is critical to all human knowledge, including the natural
sciences. Richard Feynman once wrote, “You can recognize truth by its beauty
and simplicity.” Beauty, as both scientists and theologians know, leads to
truth.
The
Nobel laureate, Subrahmanyan Chandrasekhar presented an important study in
“Beauty and the Quest for Beauty in Science” by pursuing “the extent to which
the quest for beauty is an aim in the pursuit of science.” For example, Henri
Poincaré, in Science and Method, when
answering the question of why scientists study nature at all and how they
select the facts they do in formulating scientific theory: “The scientist does
not study nature because it is useful to do so.” He continued and thereby
countered a purely instrumentalist approach to scientific work and
simultaneously described the way that beauty motivates scientific discovery, or
to use my terminology, offers scientists a telos or motivation:
He studies it because he takes pleasure in it; and he takes pleasure in it because it is beautiful. If nature were not beautiful, it would not be worth knowing and life would not be worth living…. I mean the intimate beauty which comes from the harmonious order of its parts and which a pure intelligence can grasp.
Poincaré points to harmony or
consonance as a central feature of beauty. Beauty also implies pleasure (which
has constituted key elements of theories of beauty for centuries), and thus
scientists realize the pleasure of their work in the realization of harmony.
This beauty sustains scientists’ research even in spite of the rigors of their
work: “Intellectual beauty,” he continued, “is self-sufficing, and it is for
it, more perhaps than for the future good of humanity, that the scientist
condemns himself to long and painful labors.”
Similarly, Werner Heisenberg
wrote about the connection between discovering the nature of quantum reality
and its beauty. (Worth noting below is the relationship between beauty and
Heisenberg’s “coherence,” which is parallel to my formulation of rightly
perceiving nature.) Beauty for Heisenberg is surprising and objective. As he
describes it in Physics and Beyond,
he did not impose beauty, but discovered
this beauty in the midst of looking at energy at the quantum level:
I had the feeling that, through the surface of atomic phenomena, I was looking at a strangely beautiful interior, and felt almost giddy at the thought that I now had to probe this wealth of mathematical structure nature had so generously spread out before me.
This
pursuit and discovery of beauty has certainly motivated key scientists. I could
multiply quotes, but will simply note Einstein’s use of beauty in formulating
both the special and general theories of relativity. Helen Dukas and Banesh
Hoffmann summarized Einstein’s work: “The essence of Einstein’s profundity lay
in his simplicity; and the essence of his science lay in his artistry—his
phenomenal sense of beauty.” It was that sense of beauty that led him to
reformulate our understanding of the cosmos. The particular motivation of
beauty for scientists, as Poincaré describes it, is grasping the harmonious
order of the cosmos. Indeed, in Adventure
of Ideas, Alfred North Whitehead, in Adventures
in Ideas, pointed to this ordering function of scientific and artistic
pursuits. As he wrote, “Science and art are the consciously determined pursuit
of Truth and of Beauty.” It is beauty that lures us and that makes truth worth
discovering. (See also Alejandro García-Rivera’s reflections on the importance
of the beauty as that which moves “the heart,” or the center of human action in
The Community of the Beautiful.)
We
are coming to a point where it becomes less fruitful to speak of separate
directions for theology and science, but in fact, the locus of common
understanding and more importantly, motivation. The noted physicist George Ellis,
in the lecture “Faith, Hope, and Doubt in
Times of Uncertainty,” presented beauty as the highest level of human
knowledge: “I believe that for many the
experience of great beauty is an immediate striking way of experiencing
transcendence.” Ellis noted that this leads many people to “genuinely spiritual
experience.” In Ellis (and to some degree in Whitehead), I see the confluence
of these disciplines, science and theology, in one person.
I have been noting the importance of
beauty in both science and theology as a way to demonstrate that beauty forms a
natural knowledge of God. God has created this world beautiful—as it reflects
the divine Beauty—and whether explicated as a theological category or not, that
Beauty shines through the natural world. And it is a beauty that scientists and
believers both perceive.
An
evolutionary understand of the development of the human brain provides another starting
point for a scientifically based natural knowledge of God, or at least an
openness to God. Justin Barrett, through his work in developing a Cognitive
Science of Religion (CSR), uses the findings of the cognitive sciences to argue
that evolution has developed human beings so that we implicitly see purposes in
events, or are predisposed toward teleology. As he wrote in Cognitive Science, “Evidence exists that
people are prone to see the world as purposeful and intentionally ordered,”
which naturally leads to belief in a Creator. For example, preschoolers “are
inclined to see the world as purposefully designed and tend to see an intelligent, intentional agent behind this
natural design.” Some use this tendency
to impugn belief in God—i.e., we cannot help but believe—instead I am arguing
here that it is part of God’s creation. We are created with an openness to
belief. Another area of research suggests that evolutionary pressures,
particularly the human need toward cooperation as it leads to survival,
produces a common stock of morality; “a recurring theme is that humans seem to
naturally converge upon a common set of intuitions that structure moral
thought,” such as “it is wrong to harm a nonconsenting member of one’s group.” Andrew
Newberg and Eugene D’Aquili have also studied brain activity during meditation
and prayer and found a remarkable cognitive function that supports belief in
God.
Barrett
notes that the similarities with John Calvin’s sensus divinitatis He pointed to a sense of the Numinous, powerful
and brooding. “Where can I go from Your presence? Where can I flee from Your
spirit?” cries the psalmist in Psalm 139. It is the feeling of being out in a
forest at night, knowing that no one is there, but feeling something. Often this experience can frighten us. And yet it also
provides a witness to the natural knowledge of God. And, according to Barrett, God has used
the process of evolution to implant this natural awareness.
In the next post, I'll look at how to achieve clarity in bringing all these strands together.
