So
what control do we really have over our actions? Is our brain's neuronal
firing activity just going along on its own, with no input from us?
If so, we appear to be shaped by a lot of influences beyond our
conscious control. It can even seem as if we are pawns in a game of
arbitrary brain electrical activity. Neurons fire and we simply
respond.
These
recent findings of neuroscientists are rather upsetting to many of
them. It has caused some of them to be very cautious about becoming
too visible and vocal about their results. If they were to cast doubt
on our ability to act freely, maybe they'd play into people's bad
behavior. If some people toss out the idea of having free will, they
might conclude that their choices—particularly their moral
choices—are irrelevant. Why try to behave ethically, when we're not
really in charge? My brain made me do it; I'm not responsible! And
furthermore, my brain may have made me do it, because my parents did
not give me a nurturing home life, or because their brain
chemicals were screwed up and they passed them on to me. It's not my
fault!
So
where do we go with this issue? What is the real story? Is it free
will or determinism? Am I responsible or not? I will weigh in here
and propose that it is not a case of either/or, but a case of free
will and determinism. It's both. Neither one really excludes
the other. These recent neuroscience experiments do seem to show us
that free will plays a smaller role than what we've previously
believed. But where does this leave us? What do I do with the
possibility that it might be both? How do I decide which is which?
Humans
have historically believed that free will reigns. So let me explore
what we might come to conclude if we were to go to the other extreme:
that we are fully under the influence of determinism. In other words,
what might the implications be if we maintain that only
determinism reigns.
If
we choose to believe that determinism rules—that our firing neurons
completely control our choices—we then must conclude that
our actions are not our responsibility. Thus we are not morally
responsible for what we do. There have been documented cases of
people behaving immorally when they believed that free will does not
exist. What are their lives like? Research has shown that they feel
less blameworthy. They are less likely to be generous or volunteer to
help others. They experience more stress, are less committed to
making relationships work, are more likely to feel that life has no
meaning, perform less well academically, are less creative, less
grateful, and are more likely to conform. That's a pretty lengthy
list of undesirable and unprincipled behaviors!
The
propensity of people who deny they have free will and then act
immorally, as I wrote above, has many neuroscientists very wary of
publishing the truth about the fact of our limited free will. They're
concerned that their findings may instigate bad behavior. Some even
advocate that we should go along with the illusion of free will,
while others feel that this is dishonest. They struggle with the
dilemma.
There
is a positive side to to accepting the role (if not the domination)
of determinism, however. Our criminal justice system—which is based
on free will—does not recognize the fact that some offenders simply
inherited unlucky genes, or that their brain chemistry might have
been altered by an injury. Their crimes are not always completely
their fault. This is an explosive criminal justice issue! It would
make a dramatic change in our penal system, if we accepted it. It
might even humanize the system. And it could make us less likely to
pursue a path of vengeance, when someone commits a crime.
If
society allowed a degree of determinism, it could foster a softer
view of criminal justice. It could prompt society to be more likely
to improve the environment of disadvantaged people, so they'd be less
likely to offend. It could lead us to revolutionize our education
system and help people be better able to realize their full
potential. People in a bad situation might be seen as needing help,
rather than punishment. And when punishment is called for, we might
levy it with more kindness and compassion.
When
a natural disaster strikes—such as an earthquake or a hurricane—we
do not think of extracting revenge on God or nature... we just
rebuild. The calamity was beyond our control, so who's to blame?
Could we possibly adopt some of this attitude toward those who commit
crimes? And the biggest stretch of all: could we more constructively
respond to terrorism? Our first gut reaction—influenced by our
tendency to believe in free will—is vengeance. The United States
responded to the 9/11 terrorist acts with retaliation, and then
caused far more damage around the world by doing so. It could have
been different, if determinism had been allowed to influence our
viewpoint.
So
let me return to the age-old question of whether it's free will or
determinism. I've already said that I believe it's not an either/or
situation. Neuroscience is demonstrating that determinism plays a
bigger role than we've historically believed. This is a very
important lesson. But it does not imply that we trash our
opinion that we act with free will. It's a mixture of the two.
It's complex. We must open our minds to acting in various mixtures at
various times.
We
make choices—sometimes within our conscious control, sometimes
beyond our conscious control. I think the point is to examine our
choices and subsequent actions—however they come about—and
evaluate them. How can we learn from them, so that we do a better job
next time? How do we show ourselves—and others—compassion? Won't
that help us all to become more moral?
