12. THE BLIND WATCH'S MAKER?
"In this remarkable scenario, the entire
cosmos simply comes out of nowhere, completely in accord with
the laws of quantum physics, and creates along the way all
matter and energy needed to build the universe we now see...All
of this will follow from a magnificent mathematical theory that
will encompass all of physics...in one superlaw. But we come
back to the question: why that superlaw?"
-Paul Davies1
"Things at least seem to organize themselves
better than they 'ought' to, just on the basis of blind-chance
evolution and natural selection...There seems to be something
about the way that the laws of physics work, which allows
natural selection to be a much more effective process than it
would be with just arbitrary laws."
-Roger Penrose

I began this book by pointing out that there
is a deep split between science and spirit, and arguing that
only a holarchical worldview can incorporate both these ways of
knowing the world. Almost all scientists now recognize that
there are levels of existence, each transcending and including
the one below it, and each with its own emergent properties. In
Part 1, we examined each of these levels, beginning with atoms
and physical matter, and progressing through cells, organisms
and societies.
I have also argued that the most
generally-agreed features of higher states of consciousness are
quite compatible with holarchy. In Chapter 6 we examined some of
these features, which are suggestive of a new level of existence
incorporating the entire planet. Both the emergent properties of
this new level, and its relationship to the levels below it,
exhibit principles that we have seen on each of the lower,
scientifically-accessible levels.
The holarchical view of existence, then,
consists of a series of levels or microcosmoses, one within the
next. Some of these levels are accessible to science, some to
spirit. More specifically, the methods of science are most
appropriate for investigating phenomena below our own level of
existence, while the methods of spirit are most appropriate for
investigating the levels above us. Phenomena on our level of
existence, especially higher stages of social organization, are
an intermediary realm, most accessible to the intersubjective
methods of philosophy and the social sciences.
The holarchical worldview therefore provides
a conceptual unification of science and spirit, a way of
organizing the data of each and relating them to each other.
Moreover, the operation of analogies between different levels of
existence--one of the central principles of holarchy--suggests
new ways of understanding certain known phenomena, as well as
the possibility of predicting the existence of currently unknown
ones. With respect to the first of these possibilities, we have
seen that Darwinism may be broadened by postulating that
analogous evolutionary process occur on other levels of
existence. With respect to the second, the future evolution of
the planet may follow organizational stages that can be
understood in outline at lower levels.
Nevertheless, to take the holarchical view no
further than this hardly constitutes a revolution in either
science or spirit. We have mostly added the data of one to those
of the other, and shown that there are no serious
incompatibilities. In the frequently used metaphor of a house
with several stories, we have shown that one story or series of
stories will fit on top of another group of stories, without
causing the structure to collapse. But the inhabitants of each
story continue their lives much as before. They remain within
their own part of the house, perhaps a little more aware of the
other stories, but still having little or no interaction with
their members.
The greatest potential value of the
holarchical worldview, obviously, would lie in areas where the
two ways of knowing do interact, where one way of knowing can
complement and enrich the other. Indeed, I emphasized at the
very outset of this book that neither science nor spirit can
stand alone, that the practice of either one without the other
leads, at best, to an incomplete understanding of even its own
realm. Spirit without science may believe in God, but can't
realize God. Science without spirit may explain what we observe,
but can't explain how we observe.
I have briefly discussed ways in which the
two ways of knowing might fruitfully interact. An area of clear
scientific deficiency, discussed in Chapter 5, is presented by
the so-called hard problem of consciousness--how it is that we
experience both an outer world of objects and an inner world of
mental phenomena. The obvious inadequacies of all current
theories of consciousness have led some philosophers to argue
that this problem is beyond our capacity to understand. What I
tried to show is that, first, our dualistic vision of the world
results from our position between levels in the holarchy; and
second, like any form of existence, we have an awareness in
certain dimensions of time and space which precludes us from
observing phenomena that occur in higher dimensions.
Another area of intersection of science and
spirit was suggested in Chapter 6. There we saw that we can use
the traditional scientific test of independent verification to
identify features of higher consciousness that are most likely
to be universal and real. Moreover, the concept of energy may
provide a way to understand the mystic path that is consistent
with principles of evolution on lower levels of existence.
In this chapter, I want to discuss another
area where science and spirit need to cooperate. This is the
question of our origins. The current split between the two ways
of knowing is nowhere better illustrated than in the answers
they give to this question. Science says we came from below,
beginning with physical matter; spirit says we were created from
above, as the product of an intelligent designer.
Though the scientific view of existence has
triumphantly changed much of our lives, religion still exerts an
immense influence on most people, and nowhere is this influence
more obvious than here. While many religions today accept the
idea of evolution, they nevertheless preserve the notion of a
God that preceded everything else in the universe. Nor does this
position, even after a century and a half of evolutionary
theory, appear entirely frivolous or old-fashioned. We have seen
in the preceding chapters how difficult it is to account for
some evolutionary transitions in terms of known physical and
biological processes. This has led even some scientists, like
Michael Behe (1996) and Dean Overman (1997), to argue that
evolution can't provide a comprehensive explanation of
existence. Moreover, even if we accept the premise that future
work in Darwinian theory, in self-organizing processes, and even
in some radical notion like morphic fields might satisfactorily
fill in all the gaps, we are still left with the question of how
everything began. If the universe began with physical matter,
what created the matter?
Because of doubts like these--not to mention
the need to understand questions of values, moral and meaning in
life--there is still ample room in the logic of even the most
intelligent and well-informed people for some concept of God.
Polls have consistently shown that about 90% of Americans
believe that God played some kind of role in creating us. While
perhaps half of these people adopt a fundamentalist view in
which evolution played little or no role, the other half see no
conflict between God and evolution (Johnson 1997). Indeed, there
are a significant number of theologians and religious scholars
who are actively trying to incorporate the latest scientific
findings bearing on evolution, including quantum phenomena and
self-organizing processes, into their religious worldview
(Richardson et al. 1996; Polkinghorne 1997; Peacocke 1997).
Still, if the argument for spirit were no
more than this--where did we come from?--we could not blame most
scientists for being atheists. If the scientific worldview can't
yet provide a complete answer to this question, it has
undeniably made enormous progress in that direction. The
evolution of the physical universe, beginning with the Big Bang,
and evolution on earth, beginning with physical matter, are
understood at least in general terms; what remains to be
explained is far less than it was even a century ago. Even the
ultimate question of how everything began, long thought to be
totally outside the bounds of science, is being seriously
addressed; it has been suggested that something might emerge
literally from nothing, as a quantum fluctuation (Davies 1992)?
The point is not that whether this idea, or any other
speculation about our origins, is correct. The point is that if
we extrapolate scientific progress into the future based on what
it has accomplished in the past, doesn't it seem quite likely
that it will eventually obviate the need for God as any kind of
explanatory device?
The evidence for spirit, however, is not
simply negative; it does not depend solely on the inability of
science to fill in certain gaps in its worldview. The real
evidence for spirit is direct: we can experience a higher level
or levels of consciousness above the one we ordinarily exist in.
In Chapter 6 I not only discussed the nature of this experience,
but also addressed the critical question of whether these levels
could be emergent from our own. That is, could higher states of
consciousness be simply the latest product of evolution,
following that of matter, life and mind? Though I don't believe
the evidence is totally conclusive one way or another, the fact
that more than one state of consciousness above our own has been
described by many mystics constitutes very strong evidence, in
my view, against the notion that these higher states could be
emergent from our own. If they were emergent, we would expect,
on the basis of everything we know about the evolution of lower
levels of existence, that there could be no more than one level
of existence above us.
The experience of higher consciousness thus
provides a very compelling argument for the existence of higher
intelligence preceding the creation of the physical universe. I
say this as a scientist with tremendous respect for the
explanatory power of the idea of evolution. I agree with the
hardliners on both sides of the science vs. spirit debate that
it is very difficult to reconcile evolution with God--that if
one really understands the implications of both concepts, they
seem incompatible. Yet I follow first and foremost evidence, and
the evidence for both seems to me unassailable. As a scientist,
I accept the evidence for evolution; as one who has experienced
higher states of consciousness, I accept their reality as well.
So how does one go about making them
compatible? We should surely begin by listening to those who
have accepted both, which is to say, most mystics. The mystic
view of God has long been an evolutionary one, for it identifies
its goal as not simply recognition, but realization of a higher
state of consciousness. This became clear two thousand years ago
with the development of the Mahayana or "large vehicle" form of
Buddhism. In teaching that enlightenment was open to all, it
made the further evolution of humanity a world-wide program
(Ch'en 1963; Corlett 1991).
It has been claimed that a more comprehensive
theory of evolution was created in the east by the seventh
century A.D. (Northe 1993). In any case, early in this century,
the Hindu philosopher Sri Aurobindo (1985) developed a theory
extending the evolutionary view of human beings to other forms
of existence. Consistent with early creationary theories like
the Great Chain of Being, as well that expressed in classical
Hinduist texts, Aurobindo visualized a universal consciousness
creating, by a process called involution, successively
lower levels of life. To this well-known story he then added the
contemporary idea of evolution, which was now interpreted as a
process by which life on all the lower levels returned to its
origin. So evolution was embraced as not only real, but one half
of the creative process of God. Teilhard de Chardin (1959) took
a similar view of the evolutionary process as a purposeful
return to what he called the omega point. More recently still,
Wilber (1980, 1981) has interpreted both human development and
human evolution in terms of involutionary as well as
evolutionary processes.
The conventional mystical worldview does not
solve the question of our origins, as some who promote this view
seem to believe. In fact, it has some serious problems, which I
will try to highlight in the following discussion, as well as in
the next chapter. But since no other worldview I'm aware of even
makes a serious attempt to reconcile evolution with higher life,
it's one we should consider.
E Pluribus Unum, Ex Uno Plures
The notion that the world was created by a
higher intelligence is of course an ancient idea, dating back,
perhaps, to several thousand years B.C. Referring to it as "the
shared myth of the one that became two", Joseph Campbell notes
that:
"a progressive, temporally oriented
mythology arose, of a creation, once and for all, at the
beginning of time, a subsequent fall, and a work of
restoration, still in progress."
3
In the idea of "restoration", surely, is an
embryonic form of evolution. In the West, this creation myth
became expressed in the story of Adam and Eve, two individuals
coming out of one original God. In the East, it was recounted in
one of the most famous passages in Hinduist literature, from the
Brihadaranyaka Upanishad:
"The universe was but the Self in the
form of a man. It looked around and saw that there was
nothing but itself...However, he still lacked
delight...and desired a second. This Self then divided
itself into two parts; and with that, there were a
master and a mistress."
4
As I emphasized earlier, science has great
difficulty understanding how an intelligent form of life could
apparently exist outside of time and space, without having been
itself created. Even if we pass on that, though, the idea of
involution, or "one becoming two", raises another problem, one
that mystics and theologians themselves are much more willing to
concede, or at least wrestle with: why would a perfect form of
existence create something lower than itself? The passage quoted
above, taken literally (though Campbell argued we shouldn't do
this), provides a clearly illogical answer: that something
perfect should lack delight and experience desire.
The great mystical philosopher Plotinus, who
apparently had some direct experience of higher consciousness,
was nevertheless no better able to understand why there would be
egress from this state of grace:
"Roused into myself from my
body--outside everything else and inside myself--my gaze
has met a beauty wondrous and great. At such moments I
have been certain that mine was the better part, mine
the best of lives lived to the fullest, mine identity
with the divine. Fixed there firmly, poised above
everything in the intellectual that is less than the
highest, utter actuality was mine.
"But then there has come the descent,
down from intellection [spirit] to the discourse of
reason. And it leaves me puzzled. Why this descent?"
5
After acknowledging the discussions of his
predecessors on this matter, Plotinus concludes with an
explanation no less lame than that of the Brihadaranyaka
Upanishad:
"If the souls [higher consciousness
as experienced by an individual] remain in the
intelligible realm with the Soul [that is, united with
the universal consciousness], they are beyond harm and
share in the Soul's governance...But there comes a point
at which they come down from this state, cosmic in its
dimensions, to one of individuality. They wish to be
independent. They are tired, you might say, of living
with someone else..."
6
The problem Plotinus was grappling with was
to plague Western thought throughout the Middle Ages. As Arthur
Lovejoy discusses at length in The Great Chain of Being,
the involutionary act forced philosophers to conclude that God
either a) chose to create lesser forms of life--with all the
evil and suffering they brought with them--or b) had no choice
in the matter, and was therefore not omnipotent (Lovejoy 1936).
Nor does the problem seem any less tractable to the modern mind.
In this age of evolution, we have become accustomed to thinking
of life as something that progresses from the simple to the
complex, from inanimate to animate, from less intelligent to
more intelligent, from unconscious to conscious--in a word, from
lower to higher. Involution, it follows, must be a process that
produces increasingly less complex, less animate, less
intelligent forms of existence. Stated in this way, it seems
regressive, as though life were reversing the gains of billions
of years.
There is, though, a simple way to understand
involution that makes it clear that it's not regressive.
Involution is a reproductive process; the higher
recreates itself, through the lower. We examined this process in
Chapter 4. In virtually all multicellular organisms,
reproduction begins with the creation of a single cell that
contains the potential to develop into another organism. This
cell subsequently fulfills this potential, by a process of cell
division and differentiation. The production of the reproductive
cell is an involutionary process. The development of this cell
into an organism is evolutionary process.
By this reading of the mystical view, then,
we ourselves play out, from generation to generation, the very
foundational theme of existence, the creation of universes. A
microcosm of the Absolute, we create a microcosm of our
microcosm, which then evolves to form another one of us. This
repeating process of involution/evolution is part of a much
larger but analogous process, in which a higher form of life
than ourselves created a much lower form of life than ourselves,
which is gradually evolving through many levels of existence to
return to its Creator.
This view of involution does not solve either
of the twin problems confronting any view of existence that
begins with intelligent life: how the higher form of life came
to be, and how it came to create lower forms. But let's pass on
these questions, and see where, if anywhere, the idea can take
us. To the extent that involution is analogous to the
reproduction of lower forms of life, it may provide some insight
into the evolutionary process that followed it. So, as
throughout this book, the question we want to ask is: how good
is the analogy? To what extent is reproduction of a holon like
ourselves a believable model of how the universe was created,
and has subsequently evolved?
At first view, the analogy seems a forced one
at best. In the case of reproduction, the outcome is virtually
guaranteed. The fertilized single cell contains the potential,
within its genes, to develop into another organism. Barring some
pathology, the new organism will appear, and in every sense be,
very much like the original. In the case of involution as
reproduction of the universe, we really can't compare what has
been produced so far with the original, because we really don't
have any conception of the original. Yet based on what we know
about evolution, the outcome hardly seems guaranteed. In the
view of most scientists, the evolution of all life on earth, and
especially our own species, was an extremely improbable event.
In this important respect, it could hardly be more different
from biological reproduction.
But was evolution really that improbable? The
discovery of self-organizing processes, which I discussed in
Chapter 10, presents a serious challenge to the traditional
Darwinian view. Though the details of these processes can be
understood, like Darwinism, as an interplay of chance and
selection, the outcome seems somewhat determined. Thus Stuart
Kauffman argues that many of the major transitions in evolution
were not simply probable, but perhaps inevitable, following from
certain mathematical laws. Might not the existence of such laws
be construed as evidence of an orderly reproductive process of
some higher level of existence?
Still, even the most ardent believer in
self-organization would not view evolution as a completely
determined process. For one thing, regardless of the role of
self-organizing processes in evolution, Darwinian processes, as
we have seen in Chapter 9, did play a major role. There can be
little doubt that many of the twists and turns of our natural
history occurred largely through chance, rather than as the
outcome of an inevitable process. Furthermore, even where
self-organizing processes did occur, we must be careful to
distinguish general features that might have been inevitable
from details that were more likely contingent. It may have been
inevitable for certain kinds of molecules to evolve into cells.
It's unlikely, however, that the specific molecular composition
of the cells we see today was inevitable. Likewise, even if the
emergence of multicellular organisms were inevitable, the forms
these organisms took most likely were to some degree contingent.
So the very best-case scenario we can make
for an original involutionary process is that some potential for
higher forms of life was present in physical matter. On the
other hand, before we conclude that the analogy with
reproduction in organisms is of limited value, we need to keep
in mind that biological development, too, is shaped by
contingency. As I discussed in Chapter 3, development of the
organism, though guided by genetic information, is not strictly
determined by it. Genes are best understood as providing certain
rules by which cells interact to form tissues and organs. While
the outcome in a general sense is very certain, the details are
not. There is a certain degree of randomness in the process.
Studies with genetically identical organisms have demonstrated,
for example, that they differ in the detailed connections in
their nervous systems (Levinthal et al. 1976).
Indeed, there is definitely a Darwinian
element that comes into play during development of connections
between neurons in the brain, as well as between neurons and
muscles. While not any neuron can connect with any
other--physical proximity as well as the presence of certain
interacting chemical substances plays a role--many connections
are initially formed which are later eliminated by a process of
cell death (Stellar 1995; Lichtman et al. 1999; Oppenheim 1999).
What seems to determine whether connections are permanently
established is a kind of natural selection--that is, whether the
connection is used repeatedly by the organism. Neural pathways
formed during early development that are repeatedly used are
strengthened, while those that are not tend to degenerate
(Wiesel and Hubel 1963). Thus the deep structure of the brain is
formed to some degree by a Darwinian process. Gerald Edelman has
proposed that a somewhat similar process of "neural Darwinism"
affects the surface structure as well, that is, the connections
that are formed during learning in the adult organism (Edelman
1989).
In summary, while development appears to be
far more of a determinate process than evolution, the view that
evolution may be to some degree analogous to development is not
entirely fanciful. Development, like evolution, is shaped by
Darwinian processes, and perhaps also by self-organizing ones,
which seem to play a role in molecular and physiological
processes in organisms (see Chapter 10). Moreover, just as I
noted earlier (Chapter 4) that we must be cautious about drawing
analogies between holons or levels that are complete and those
that are apparently still in the process of evolving, so one
might argue that if evolution of life on earth is indeed part of
the reproductive process of a higher form of life, this process
itself may be evolving. We might view it as an early stage of a
property that at some later point will be capable of a much more
determinate form of reproduction.
So let's presume that evolution can be
understood as some kind of cosmic development process. What
other features with biological development does it share? As I
just pointed out, the development of higher organisms is guided
by more than the genetic information in their cells. It also
requires a particular environment in which to develop. For
mammals, this environment is provided by the womb of the mother,
and after birth, by the society of others of the same species.
In other words, in addition to the informational potential that
is provided within the developing new species, there is also
potential provided from without. The higher level of existence
is not only compressed within the developing organism's genes,
but also envelopes it as it unfolds.
Pursuing our analogy of development and
evolution, we might ask whether a level of existence beyond our
own could provide a similar environment. The conditions on
earth, by definition, have been favorable to evolution, at least
not incompatible with it. The earth is the correct distance from
the sun, has an aqueous environment, the presence of certain
gasses, and so forth. In the traditional scientific worldview,
this is purely a matter of chance. There are numerous galaxies
in the universe, and the laws of probability are perhaps such
that a few contain solar systems where the starting conditions
prevail for the evolution of life as we know it. But this is not
necessarily an argument against what I'm calling a developmental
model of evolution. We know that many plants and organisms
reproduce by creating a very large number of involutionary
holons--i.e., seeds or eggs--a vanishingly tiny portion of which
go on to develop and mature into a new organism.
This mode of reproduction is particularly
common among plants and invertebrates--lower, less evolved forms
of life. HIgher forms of life--in particular, birds and
mammals--produce fewer offspring, but generally a much larger
percentage of the latter survive and mature. So again, we are
confronted with the possibility of a reproductive process that
is still evolving. Evolution on earth can be viewed as a the
product of a seed--physical matter--that happened to fall on a
propitious spot. At this stage in the evolution of the
reproductive process, nothing more is done. The seeds are
produced in large enough quantities so that a few will go on to
develop.
The Agent of Selection
In the preceding section, I have tried to
argue that there is a certain degree of analogy between
development of individual organisms and the evolution of life on
earth. Of course, even if we accept this argument, hardly a
compelling one, this doesn't prove that evolution is part of a
reproductive process of a higher form of life. It could be
simply that development is making use of the same processes that
evolution discovered, slowly and laboriously. And even if
evolution is part of such a cosmic reproduction process,
understanding it in this way clearly doesn't much change our
scientific view of the world. We have simply substituted a
creationist view of the origins of matter, for that of
science, then let nature take its course.
In the mystical view, though, higher
consciousness does more than just create the physical world. It
guides its evolution in some manner, infuses it with purpose to
ensure that the lower will indeed become the higher (Teilhard de
Chardin 1959; Aurobindo 1985; Wilber 1981). This view, it seems
to me, is not easy to reconcile with the facts of evolution as
we now understand them. We can't deny that the process has taken
an incredibly long time to get to where it is now, a period many
orders of magnitude longer than the development of any new
organism. Moreover, while the higher has followed the lower,
this has not been a completely linear process. Evolution is more
like a bush than a tree, says Stephen Jay Gould (1977b, 1990).
While I think he is missing the forest for his bushes, we surely
can see that even if evolution of human beings, or some form of
relatively intelligent life, was inevitable, it did not come
about in the most direct possible manner. If a higher form of
life is guiding the process, it is surely operating under some
mighty strong constraints.
In Chapter 8 I argued that there is an
information gap between different levels of existence; the
quantity of information in the informational holon of one level,
such as the genome or the brain, is not sufficient to account
for the quantity found in the next. We subsequently saw that
there is a very close relationship between information and
selection. Self-organizing processes, as well as Darwinian ones,
can be understood in terms of selection, suggesting that a
broader evolutionary theory should be based on this idea.
Selection does seem to create information, in Chaitin's sense.
Any process that can reproducibly pick out one complex string
from many others generates information. So the question is, how
does selection occur? Could a higher level of existence have any
effect on evolution in this manner?
While Darwinism was widely perceived as
incompatible with an active role of a Creator in the emergence
of life on earth, the principle of selection has never fit
perfectly snugly in the "natural" world. As many evolutionary
biologists have pointed out, the term seems to imply some sort
of outside agency, not so much denying the existence or activity
of God as re-interpreting what that activity is:
"Darwin's notion of natural selection
can be enthroned in God's stead as the creative agency.
The conceptual structure is already in place; only a
kind of governmental revolution and regicide are needed.
Selection slips into place as an agency creating order
from chaotic variation."
7
It was for this reason, indeed, that Herbert
Spencer--not Darwin--suggested the terms "survival of the
fittest", which seemed to make it clear that no supernatural
process was at work. However, use of this term has its own
problems. Karl Popper, one of the most ruthlessly critical
philosophers of this century, accused it of being tautological,
that is, self-defining or circular (1976): Why does a particular
species survive? Because it's fitter. How is fitness determined?
By survival. Most Darwinists believe Popper has been refuted
(Stamos 1996), yet neither fitness nor survival seems yet to
have found a definition entirely independent of the other.
Lima-de-Faria (1988) points out, moreover, that selection is one
of the very few fundamental scientific terms that can't be
expressed in measurable units.
The root of this problem, surely, lies in the
fact that Darwinists, by focussing on fitness, are aiming at a
moving target. The forces of selection, as they define it, are
constantly changing. As organisms evolve, so does their
environment, which to a large extent is composed of those
organisms. Thus an environment that favors a certain kind of
adaptive fitness may later change--indeed, usually will change
as evolution proceeds--so that it no longer favors that
particular adaptation. This makes it essentially impossible to
predict a priori what features are adaptive. Adaptive
fitness and survival are very much determined by context.
Perhaps a better way to define selection
would be survival of the most stable, as Dawkins (1976)
suggests (see Chapter 10), or as the most efficient--that
is, of those forms of life that transform energy with the least
amount of waste, or dissipation. While in one sense such a
definition is still tautological
8,
it clearly has the potential to break out of the circle. Given
enough knowledge about organisms and other forms of life, we
should be able to measure their efficiency, and thus make a
priori judgments about their ability to survive. Efficiency,
like survival, is relative and contextual, but is rooted in
features that are not.
While most evolutionists would agree that
efficiency is important, many might argue that it can't be
viewed as the fundamental driving force of the process. We can
easily point to examples of life that don't seem to fit the rule
of greater efficiency--the peacock and its huge tail, for
example. In traditional Darwinian terms, the tail is explained
in terms of reproductive fitness--it is better at attracting
mates than a smaller tail. Period--end of explanation. If we
were to interpret evolution strictly in terms of efficiency, the
peacock would not seem to make sense.
An even better, if much less appreciated,
example of apparent inefficiency is the human brain, which
spends most of its time and energy on useless
thoughts--daydreams, fantasies, old memories, and so on. Again,
this inefficiency can be understood in terms of reproductive
fitness--reproduction, however, not of genes but of
memes (Blackmore 1999). The junk that repeats itself
endlessly in our minds is passed along from one individual to
the next, in this view, because it's more reproductively fit
than competing types of thoughts which might, from an individual
point of view, be more efficient. Thus as Blackmore notes,
popular tunes reproduce themselves memetically much faster and
extensively than more serious thoughts concerning, say,
political, social or scientific ideas.
These examples suggest that in order to
understand evolution as a drive creating more efficient forms of
organization, we have to focus on the highest levels of
organization in existence. The male peacock as an individual may
be inefficient as birds go; a population of peacocks that
maintains its existence through reproduction may be more
efficient than a group of less ostentatious birds. Likewise,
individual human beings may be mentally inefficient; social
organizations of human beings, held together by rapidly
reproducing memes, may be highly efficient. Central to this
argument is the notion that much of the energy that individuals
seem to be wasting is in fact being used--by a
higher level of existence
9.
To the extent that any group, population or
society of organisms requires reproduction to maintain itself,
the traditional view of reproductive fitness is still a powerful
one by which to understand how it has evolved. We might say that
viewing evolution as the creation of ever more efficient forms
of organization often reduces to a view of simple
reproductive fitness. Reproduction is a kind of group
metabolism. Any new adaptation that allows a form of life a
reproductive advantage over its competitors enhances this
metabolism.
But reproduction, as Ian Tattersall reminds
us, is not the only aspect of this "metabolism", nor, for higher
organisms, even its most important one: "The amount of time and
energy each individual invests in economic pursuits over his or
her lifetime vastly outweighs what is spent on reproductive
activity."

In other words, in the phrase "survive and
reproduce", the emphasis is generally on survival.
Selection defined in terms of efficiency, it
should be apparent, strongly implies holarchical organization.
We saw in Chapter 3 that associations of holons of a similar
kind can be specified with much less information, and therefore
less energy, than other types of organization. We have also seen
that many types of self-organizing processes, such as
autocatalytic networks, are highly efficient, because products
of one reaction are used as catalysts of another. To say that
selection is survival of the most efficient, then, is virtually
to say that selection creates holarchy. Survival of the most
efficient, in the long run, is survival of the highest.
Selection is no longer viewed as a process that can create
anything, contingent on what else exists now and what existed in
the past. It has to create levels of existence; anything else is
not the most efficient way to go. Not only is a group of holons
organized in a certain fashion more efficient than the same
holons unorganized, but a new holon consisting of several
different stages of social holons is still more efficient. The
details of this organization may be unclear a priori; but
the general principles are fixed.
Given that this kind of selection strongly
implies development of higher forms of life, we may
legitimately ask if it also implies pre-existence of the
higher. Here, it seems to me, is where we get into the no-man's
land of arguments about intelligent design vs. bottom-up
evolution. Even some scientists who thoroughly reject the idea
that the universe was created by a higher form of intelligence
note there is a problem in understanding why the universe has
its particular physical laws. If these laws imply a potential,
present from the beginning, to develop into much higher forms of
life (more energy, more information, more complexity), isn't
this some kind of argument from design?
I'm not going to take the argument any
further than this, because I don't think it can be taken any
further. I only want to re-emphasize two important observations,
both of which are rarely appreciated by one and the same
theorist: 1) evolution is an inordinately slow process that
seems to create higher from lower, but by a very indirect means;
and 2) there are higher levels of existence accessible to human
beings that can't be explained by evolution, because the latter
process should not yet have created them. To say any more than
that there was some potential for a higher form of life from the
beginning is to ignore the evidence that evolution has proceeded
extremely slowly, gradually and often indirectly from one level
to the next. But to say anything less would be to ignore the
evidence for spirit. Anyone who really understands both forms of
evidence--and unfortunately, there aren't many people who
do--will realize how difficult it is to make them compatible.
