"I happen to believe that you can't study men; you can only
get to know them, which is quite a different thing."
--C. S. Lewis [3]^1
"So organisms must be explained as organisms,
and not as a summation of genes."
--Stephen Jay Gould [4]^2
I begin with some sentences from Ernest Hemingway's The Old Man
and the Sea:
He looked down into the water and watched the lines that went
straight down into the dark of the water. He kept them straighter
than anyone did, so that at each level in the darkness of the
stream there would be a bait waiting exactly where he wished it to
be for any fish that swam there.... I have no understanding of it
and I am not sure that I believe in it. Perhaps it was a sin to
kill the fish.... He urinated outside the shack and then went up
the road to wake the boy. He was shivering with the morning
cold.... Then he was sorry for the great fish that had nothing to
eat and his determination to kill him never relaxed in his sorrow
for him. How many people will he feed, he thought. But are they
worthy to eat him?... That was the saddest thing I ever saw with
them, the old man thought. The boy was sad too and we begged her
pardon and butchered her promptly.... The boy did not go down. He
had been there before and one of the fishermen was looking after
the skiff for him. [5]^3
Hemingway's prose is, of course, generally regarded as clear and
straightforward. And I suspect that any single sentence in the passage
above is probably simple and transparent to you. I also suspect that
the whole of it probably makes almost no sense at all. There's a
reason for that. The sentences were drawn from pages 29, 104-5, 22,
74, 48, and 123--in that order.
One of the great blessings of the computer age, our students are
sometimes told, is that you can move sentences or whole paragraphs
around with ease. You needn't really have a thesis and its
accompanying arguments worked out when you sit down to write a paper.
Just write--and then move the pieces around later. This advice is
given as if the argument of the paper were somehow built up from
below--from words, phrases, and sentences moved around, combined and
recombined. As if a thesis would just emerge without an organizing
intelligence, an authorial perspective, at work from the outset. As if
we could explain what is lower, the argument of the paper, without
what is higher, the author.
My thesis is that we ought not make a similar mistake when we
think about genes. Consider the image at work in the following
frequently quoted passage from Thomas Eisner, a biologist from Cornell
University:
As a consequence of recent advances in genetic engineering, [a
biological species] must be viewed as...a depository of genes that
are potentially transferable. A species is not merely a hard-bound
volume of the library of nature. It is also a loose-leaf book,
whose individual pages, the genes, might be available for selective
transfer and modification of other species. [6]^4
Of Eisner's analogy, Mary Midgley comments: "The idea of
improving books by splicing in bits of other books is not seductive
because in books, as in organisms, ignoring the context usually
produces nonsense." [7]^5 I have tried to provide a humble
illustration of this by splicing together sentences from different
pages of just one book--producing thereby something unintelligible.
Letting our imaginations roam just a bit, I might also have spliced in
sentences from Anna Karenina and A Christmas Carol--producing thereby
a kind of horror. The problem with doing this is not only, as Midgley
suggests, that we completely ignore context. It goes yet a little
deeper. Such an image of a book ignores the presence of an authorial
hand. It ignores the fact that a book is not just the sum of a number
of words, sentences, or paragraphs. A book is a whole, with its own
integrity.
Human Beings as Collections of Genes
This train of thought was first suggested to me by one of the
findings of the Human Genome Project, a finding that got quite a bit
of attention in news articles announcing (in February, code 2001 /code
) the completion of that project by two groups of researchers. We were
told that the number of genes in the human genome had turned out to be
surprisingly small. Thus, for example, human beings have, at most,
perhaps twice as many genes as the humble roundworm, and the degree of
sequence divergence between human and chimpanzee genomes is quite
small. Considering the complexity of human beings in relation to
roundworms and, even, chimpanzees, it seemed surprising that,
relatively speaking, much less complex organisms do not have far fewer
genes than human beings.
Why, one might ask, should that seem surprising? It is
surprising if you assume that the complexity of a "higher" being is
somehow built up and explained in terms of "lower" component parts. If
we explain the higher in terms of the lower, it makes a certain sense
to suppose that a relatively complex being would need lots of
component parts--at least by comparison with a less complex being.
And, of course, one might argue that the Human Genome Project is "the
ultimate product of an extreme reductionist vision of biology that has
held that to understand better one need only to go smaller." [8]^6
Thinking about human beings that way is, in a sense, just the
last stage in a long movement of Western thought. First we learned to
think that qualities of objects are not really present in the object
but are supplied by the knowing subject. Then some philosophers
suggested that the objects themselves--and not just their
qualities--are simply constructs of the knowing subject. But what
happens when even that subject disappears? When this reductive process
is applied to the human subject, we get, as C. S. Lewis noted in a
witty passage,
a result uncommonly like zero. While we were reducing the world to
almost nothing we deceived ourselves with the fancy that all its
lost qualities were being kept safe (if in a somewhat humbled
condition) as "things in our mind." Apparently we had no mind of
the sort required. The Subject is as empty as the Object. Almost
nobody has been making linguistic mistakes about almost nothing. By
and large, this is the only thing that has ever happened. [9]^7
In The Abolition of Man Lewis powerfully depicts the movement by
which things came to be understood as simply parts of nature, objects
that have no inherent purpose or telos, and which can then become
resources available for human use. Hence, the long, slow process of
what we call conquering nature could more accurately be said to be
reducing things to "mere nature" in that sense. "We do not," Lewis
writes,
look at trees either as Dryads or as beautiful objects while we cut
them into beams: the first man who did so may have felt the price
keenly, and the bleeding trees in Virgil and Spenser may be far-off
echoes of that primeval sense of impiety.... Every conquest over
Nature increases her domain. The stars do not become Nature till we
weigh and measure them: the soul does not become Nature till we can
psychoanalyze her. The wresting of powers from Nature is also the
surrendering of things to Nature. As long as this process stops
short of the final stage we may well hold that the gain outweighs
the loss. But as soon as we take the final step of reducing our own
species to the level of mere Nature, the whole process is
stultified, for this time the being who stood to gain and the being
who has been sacrificed are one and the same. [10]^8
Although my central focus, like Lewis's, is on what happens to
human beings when we think of them simply as collections of genes, it
is important to note that this reductive understanding may be
misplaced even when applied to lower creatures. Lewis himself suggests
as much--that science does a kind of violence even to trees when
understanding them simply as natural objects. In our own day, we have
gone beyond the kind of quantitative reduction to parts that Lewis
pictures. We are on the brink of losing organisms altogether. When
organisms become things entirely lacking any self-definition, they
become malleable and available for reprogramming. Biological
boundaries between organisms become "historically contingent products
of gradually accumulated genetic change," and, therefore, those
boundaries can be "slightly breached with only slight consequences."
[11]^9 Living beings, including human beings, become collections of
bits of genetic information to be combined and recombined in countless
possible ways. At one time we might have thought that the scientific
attempt to understand the higher in terms of the lower was just that:
a search to understand. Now, however, wisdom gives way to power. For
now there may be nothing there to know--except what we assemble and
create. And genes are the resource we use in this creative process.
Within the discipline of bioethics, this approach will have its
effect via a theory of justice. Begin in this genetic age to think of
human beings as constituted by their parts, and you will find yourself
thinking of genes as resources that may or may not be justly
distributed. Even as we might think about the just distribution of
wealth, or food, or education, or medical care, so also we might think
of the bundles of genes that, on this view, constitute our selves as
simply another resource, which can be distributed justly or unjustly.
In an older way of thinking, there were human beings and there
were resources. We did justice or injustice to human beings by what we
did with those resources. But now we will be invited to think of
justice or injustice in the making of human beings--which is what we
do when we distribute genetic resources. [12]^10 And, in fact, going
one step further, there will be no compelling reason to think that the
genetic resources to be distributed need be confined to DNA from the
human species. [13]^11 Human beings are simply creatures to be
fashioned out of available genetic resources, and the only moral
question will be whether those resources are fairly distributed.
The Mythic and Religious Dimensions of Genes as Resources
Somewhere back in the depths of that consciousness which we will
still imagine ourselves to have, we may detect a nagging worry. Who
exactly are these beings who make decisions about how to distribute
our genetic resources? What entitles them to make such judgments? In a
world devoid of any inherent value or purpose, in which organisms lack
any self-definition, it is not clear that we should be talking about
justice or injustice. Why should we think some people wronged if they
do not get a fair share of genetic endowments? That may be their
misfortune, but what responsible agent has wronged them? In such a
world, we cannot blame God or, even, Nature.
Justice or injustice can be nothing more than a construct we
impose--not only upon ourselves, but also upon those future
generations whom we fashion from the genetic resources we distribute.
We have, in fact, no more moral ground for anointing one particular
distribution as just than another. What we have is creative power.
This is what happens when we can no longer blame something higher--God
or Nature--for our condition.
Unless, of course, we are god--or, at least, some of us are. Let
us suppose that neither God nor Nature can any longer be held
responsible for the future of the human condition. But suppose also
that we remain morally serious; we believe it makes a difference, a
moral difference, how genetic resources are distributed to future
generations. If neither God nor Nature is available to shoulder that
moral burden, but if seriousness requires that someone shoulder it,
who remains as a likely candidate for such responsibility? Only, I
think, humanity--now conceived as godlike in its utterly free creative
power and its responsibility for the future.
The vision that underlies the view of genes as resources is
powerful and appealing precisely because of its mythic dimension.
Rather than thinking of organisms as the result of an evolutionary
process (generated by natural selection), we may think of organisms as
self-creators, constantly organizing and reorganizing themselves by
reordering their genes. Thus, genetic engineering is in accord with
nature; it is nature's way of generating the ongoing evolutionary
process. If we miss the powerful mythic and religious dimensions of
this account--if we think of it simply as a neutral, scientific
picture of the universe--we will miss much of its appeal. For example,
Lee Silver ends his book, Remaking Eden, imagining some future
generation of "GenRich" creatures, for whom homo sapiens had been a
distant ancestor:
These beings have dedicated their long lives to answering three
deceptively simple questions that have been asked in every
self-conscious generation of the past.
"Where did the universe come from?"
"Why is there something rather than nothing?"
"What is the meaning of conscious existence?"
Now, as the answers are upon them, they find themselves coming face
to face with their creator. What do they see? Is it something that
twentieth-century humans can't possibly fathom in their wildest
imaginations? Or is it simply their own image in the mirror, as
they reflect themselves back to the beginning of time...? [14]^12
This is not science, of course; it is myth. It could not
possibly appeal to us as powerfully as it does were it not for that
mythic dimension, and as such it invites our sustained attention and
critique.
This myth is, first and most important, radically dualistic.
[15]^13 When genes become resources and organisms lack
self-definition, they become amenable to indefinite reprogramming. For
a long time human beings contented themselves with the pleasant
thought that they were subjects who objectified and constructed the
rest of the world. Now, however, we too become constructs, as our
genes are spliced and exchanged. But, then, who is doing the
programming? Whose project are we? Clearly, there is a ghost in the
machine, as dualists have always believed. We are both programmer and
programmed, both manufactured body and ethereal manufacturer. And
where do these two come together, if not in the pineal gland? We
cannot say. But it appears that the real self can hardly be a body;
for the body can be shaped and reshaped as we distribute genetic
resources.
The initial dualism, therefore, is metaphysical. In what looks
at first to be a materialist, reductionist age, bodily form is
indefinitely malleable. But the real self--that powerful, creative,
ordering intelligence--is not body; it must be something different.
For any future our impoverished imaginations can conceive, that real
self no doubt needs the body as a kind of beachhead in our world--a
mode of entry by means we cannot fathom--but the body is, finally,
mere natural object. For the real self--the creative, constructive
self--we will have to look elsewhere.
Were this the end of the dualism, were it merely an idea,
perhaps it would do little harm. But ideas have a way of taking shape
in life, and if sheer metaphysical dualism of body and self cannot
really be lived, those who think in its terms will find a vulgar
translation. In place of the dualism that separates the ghost in the
machine from the body will come the dualism that separates some human
beings (the programmers) from others (the programmed). Who will
undertake to design our future descendants? "It cannot be the human
race as a whole," Mary Midgley writes,
they wouldn't know how to do it. It has to be the elite, the
biotechnologists who are the only people able to make these
changes. So it emerges that members of the public who complain that
biotechnological projects involve playing God have in fact
understood this claim correctly. That phrase, which defenders of
the projects have repeatedly dismissed as mere mumbo jumbo, is
actually a quite exact term for the sort of claim to omniscience
and omnipotence on these matters that is being put forward. [16]^14
In short, the very first moral casualty of this dualism is human
equality in the relation between the generations; for Midgley is, in
effect, echoing the point made by C. S. Lewis a half century earlier:
"Each new power won by man is a power over man as well." [17]^15
There is a second thing to notice about this myth: namely, how
powerfully religious it is. Perhaps it is good to remember that when
the magician Merlin makes his appearance in Geoffrey of Monmouth's
twelfth-century History of the Kings of England, he is both magician
and engineer. In the kingdom of Britain, there is no one more skilled
"either in the foretelling of the future or in mechanical
contrivances." [18]^16 It is Merlin who oversees and enables the
engineering marvel of moving to Britain the rocks that form
Stonehenge; it is also he who magically disguises King Utherpendragon
so that, seeming to be Gorlois, Duke of Cornwall, he may sleep with
the Duke's wife Ygerna, by whom Arthur is conceived. That powerful
capacity to engineer and reconstruct is intimately related to the
magician's desire to tap into power more-than-human, and for precisely
that reason genuine science must be governed by a sense of limits.
We should not underestimate how deeply this desire for godlike
power infects our humanity. It is, after all, central to such stories
as the Fall of Adam and Eve, or that of Prometheus. Because this
desire--which is ultimately a desire not for wisdom but for
power--infects us so deeply, we do well to anticipate that even the
most altruistic of our projects may be corrupted by it. When a
religious quest goes bad, after all, it becomes demonic. The sense
that we can treat our genes as resources to be combined and recombined
indefinitely has been called "algeny," a name intended to remind us of
"alchemy," the quest to transform base metals into gold, which was
itself both scientific and religious in character. If we do not see
these connections, we miss the human meaning of what is happening in
genetic advances, and we fail to see how the thirst that drives and
underlies the bioengineering project may sometimes be idolatrous.
Dualistic and religious in character, this great mythic vision
of genes as resources, this sense that we might have within our grasp
a power very near the secret of life, is also utopian. The project of
human improvement, of overcoming suffering and enhancing capacities,
knows no end. There will always be another disease to overcome, more
years to be added to life, more points to be added to the intelligence
quotient. Jeremy Rifkin, who was largely responsible for popularizing
the term "algeny," has noted how the alchemical quest "was to help
nature in its struggle to `perfect itself.'" [19]^17 Likewise, Rifkin
suggests, the "algenist is the ultimate engineer." [20]^18 Cooperating
with a nature understood to have only very fluid boundaries between
organisms, treating genes as resources to be combined in ever new and
better ways, we place our hope--and, in a sense, our virtue--in the
future. If that perfected future never comes, or, if it comes and
turns out to be one marked by power rather than wisdom, we will have
to be justified by only our good intentions, and I doubt that they are
adequate for the task.
Thinking of Human Beings from Above
If this does not sound like a desirable path into the future,
perhaps we need to rethink the image of genes as pages in a loose-leaf
book, to be transferred and combined at will. We need, that is, to
rethink the meaning of our humanity. Writing about human embryo
research, Courtney Campbell contrasts reproduction and procreation in
order to express a point not unlike the one I have been making.
[21]^19 When today we speak of reproduction, we are likely to think of
genes as the "`building blocks of life'" and of the person as
"conceived, as it were, from the genes up." The embryo is then simply
a cluster of dividing cells. Often, however, as Campbell notes, such
an angle of vision may detach reproduction from its larger human
context and from "the meaning and purposiveness" we find in
procreation. Taken alone, reductionist thinking about the embryo turns
out to subvert "the primary ethical rationale for engaging in research
on the human embryo." For that rationale is understood in terms of
"advancing particular human purposes." From one angle we entirely
empty our vision of human purpose or meaning; yet everything we
propose to do depends on the presence of such fundamentally human
understandings.
Can we at least begin to contemplate other, more satisfactorily
human, ways of thinking about our humanity? Anything I say here must
be inadequate, but it is important that we begin this process of
rethinking. Rather than understanding the human being--the higher
organism--in terms of what is lower, we may need to recapture a way of
thinking that begins with what is higher and does not think of human
beings as collections of bits of genetic information. "[T]he key to
complexity," Stephen Jay Gould wrote shortly after the findings of the
genome project were announced,
is not more genes, but more combinations and interactions generated
by fewer units of code--and many of these interactions (as emergent
properties, to use the technical jargon) must be explained at the
level of their appearance, for they cannot be predicted from the
separate underlying parts alone. So organisms must be explained as
organisms, and not as a summation of genes. [22]^20
If we insist on starting from below in thinking about our human
nature, we will miss much of the depth of the human person. [23]^21
Imagine someone who wants to translate from a language with a large,
varied, and subtle vocabulary into a language with a much smaller and
less varied vocabulary. How can one do this? Only by giving more than
one sense to words in the language into which one is translating. And,
of course, a speaker of that language--who knew only it--might
obstinately insist, "No, that's not the right way to use this word."
He would be approaching the richer language from below, as if the
richer could be made up simply of words drawn from the limits of his
own, less subtle language.
Likewise, a man in love with a woman and a man lusting after a
woman may experience many of the same physiological "symptoms." If we
have never been in love, or if we insist on acting as if we have never
been in love--if that is, we persist in looking at the experience only
from below, in terms of its physiological symptoms--we might argue
that there is no difference between love and lust. Only one who began
from above, who knew what it was to be in love, would see at once that
these experiences are not the same. If, however, we insist that love
must be analyzed and understood entirely in terms of those
physiological symptoms, we cut ourselves off from an entire realm of
human wisdom. We will never know what it means to be in love.
Were we really to think of human beings from above, to eschew,
at least for certain moments and purposes, reductionistic modes of
thought, it would be no surprise for us to learn that the relative
"richness" of human life is not simply a matter of our having more
genes than other organisms. Thinking from above, we would stop
thinking about human beings simply as collections of resources, which
it was our duty to distribute in creatively fashioning the next
generation. We would be protected, at least somewhat, against thinking
of our relation to future generations chiefly as an exercise of power
in the making and remaking of humanity--even if such power is cloaked
in the language of a theory of justice. In short, if we were to master
the genies who invite us to think and desire in certain ways, we would
have far less to fear from the ongoing attempt to master our genes.
