Bill McKibben's latest book, Enough: Staying
Human in an Engineered Age, raises some
fundamental questions about who we are, what we
are, and how we may be affected by the
biotechnologies which we already possess and those
which are just over the horizon. The author takes
us on an expedition into the world of genetic
research, nanotechnology and robotics.
This is a passionate book and a disturbing book
and one that presents what we in the "argumentation
trade" might call a "persuasive" argument, that is,
a presentation of facts which are used, not to
support a conclusion that may be true or false, but
used to support a conclusion promoting a particular
policy or course of action.
Enough is also a revealing book, a hard
and detailed look at our rapid acceleration into
technologies which may have permanent and adverse
effects on the future of human beings; indeed,
these technologies have the potential to affect
what it means to be human at all.
Because he perceives this to be a threatening
situation, McKibben discusses technologies such as
germline engineering and therapeutic cloning,
warning that they represent a slippery slope that
may make more dangerous and harmful technologies
possible and even acceptable.
"[I]f we aggressively pursue any or all
of several new technologies now before us," the
author says, "we may alter our relationship not
with the rest of nature but with ourselves. First
human genetic engineering and then advanced forms
of robotics and nanotechnology will call into
question, often quite explicitly, our understanding
of what it means to be a human being."
McKibben acquaints us with microscopic nanobots
cruising our bloodstreams, attacking pathogens
within our bodies and building new cells. And with
children born so genetically enhanced that they
will never be able to believe that they reached
success as musicians or artists or athletes or
whatever because there was something unique in them
and a hunger to reach the pinnacle of their ability
through their own choice and desire.
The author tackles what it means to be human,
pointing out how these new technologies threaten
our very identity as human beings. "What if we have
been programmed," he asks, "or at least must
suspect each time we choose a path that we have
been nudged in that direction by our engineered
cells? Who then 'are we'?"
One of the more interesting arguments that
McKibben makes, in my opinion, has to do with the
matter of "choice," an issue with which
libertarians are always concerned.
Libertarian-minded thinkers tend to be among the
strongest advocates of modern technologies and tend
to believe that the free market will police itself
in regard to any dangers which may result from
their use.
More often than not, libertarians accuse those
who oppose or may merely question the effects of
new technologies of being Luddites, a name
attributed to that infamous group of early
nineteenth century workers who protested against
the introduction of new labor-saving technologies
in the factories of that period.
But McKibben argues that some of these new
biotechnologies are really "anti-choice." He points
out that "In widespread use, they will first rob
parents of their liberty, and then strip freedom
from every generation that follows. In the end,
they will destroy forever the very possibility of
meaningful choice."
I think that's a point that needs to be
thoughtfully and seriously considered, especially
by those who are, like I am, more or less on the
libertarian side of the socio-political
spectrum.
McKibben is not a naive thinker. He realizes
that there is no limit to human aspirations or
desires. And our ability to discover new scientific
facts and to invent new technologies seems
unlimited. But can we draw a line and say this far
and no further? Can we say, this is enough? The
author answers yes, and argues that only by staying
human can we find true meaning in our lives. What
sets a human being apart from other beings in this
world of ours? McKibben argues that it is our power
of self-limitation. "We need to do an unlikely
thing," he says. "We need to survey the world we
now inhabit and proclaim it good. Good enough."
While allowing that many of these new
technologies may hold the promise to cure disease
and provide other benefits, they also offer
problematic choices such as the capacity to choose
a child's gender, the power to boost human
intelligence and, what may be the nightmare of all
nightmares, the option of "improving" or
"perfecting" human beings. And, I have always
argued and will continue to do so: just because we
can do something does not mean it is something we
should do or need to do. I find myself having to
agree with McKibben when he concludes, "I think the
stakes in this argument are absurdly high, nothing
less than the meaning of being human. Must we
forever grow in reach and power? Or can we, should
we, ever say,'Enough'?" Maybe so, maybe in this
case, maybe at this time.
This is a book that should be read by everyone
who is concerned about the future of the human
species.
