You will frequently hear certain anti-religion science bloggers and
commenters on these boards saying that the only way for a
non-atheist to be a good scientist is to “compartmentalize”— to
wall off a part of his mind while doing science, and likewise to wall
off the scientific part of his mind while thinking about his
religion.
Do I agree with this? Yes and no.
In the yes column: obviously, we have to wall off, to some degree,
our religion when doing science, but no more so than we must wall off
many other parts of our humanity. If you let your preconceptions
from your religion influence your interpretation of the data, then you
fall into the
href=http://scienceblogs.com/interactions/2007/05/intelligent_design_a_trap_for.php"">“Intelligent
Design Trap”. Scientists who conclude that there is “evidence for
design” in the Universe are not scientists who are really making good
scientific conclusions from the data; they are torturing the scientific
process in order to allow for it to produce the result that their
philosophical preconceptions led them to.
But there are many other ways in which we must wall off parts of our
experience as human beings in order to avoid “investigator bias.” I
strongly recommend that everybody read
href="http://pinker.wjh.harvard.edu/books/tbs/index.html">The Blank
Slate by Stephen Pinker. This book is subtitled “The Modern
Denial of Human Nature,” and is an exposition and analysis of bad
science that came out of the political left. In the early 20th century
(and, unfortunately, still now), some racist and/or sexist scientists
have used biased or incorrect data to claim that there is evidence that
race or gender A is inferior to race or gender B. The reasonable
response to this is that legally we should treat all as being equal, and
not judge their capabilities from assumptions based on their race or
gender. However, this led to the philosophical preconception that in
reality, all people are created strictly equal. This is what
Pinker calls the doctrine of the “blank slate.” We are born with
nothing, with infinitely plastic brains, and everything we
develop is imposed upon us from outside: our parents, our siblings, our
culture. As evidence mounted that, even though our brains are
amazingly plastic and adaptable, we do have a lot hardcoded as
humans, and, what’s more, different people do have different natures,
there were a lot of scientists who would shout down this evidence. Why?
Because they had based so much of the argument for political equality on
the notion that people are born cognitively identical that evidence to
the contrary would be used to attack that political argument.
So, yes, very clearly you need to make sure that your ideology and
philosophical preconceptions do not warp your interpretation of the
scientific data. Religion can do it, as can political philosophy. (A
second lesson I would take from this is that one must be careful when
basing your ideology on a scientific conclusion. There are a lot
of good reasons for egalitarianism, and we do not need the false
argument that human nature doesn’t exist to support it! Likewise, I
think that theists are making a mistake when they point to our
href="http://brahms.phy.vanderbilt.edu/~rknop/blog/?p=68">ignorance
about the moment of the Big Bang as a place where we can fit God the
Creator. What will happen when we develop a theory of quantum gravity
and do address that event scientifically? We may end up going around
the Galileo track yet again, just as we are doing with evolution
today.)
One can think of other, more personal examples. I could (but won’t)
name several astronomers whom I find insufferable, arrogant, annoying,
and irritating. However, that is not a reason for me to disregard their
papers or devalue their scientific work. I have to put aside—
“wall off” if you will— my personal feelings when viewing their
work as scientists. Similarly, I can name some scientists whom I really
like as people. And, yet, I shouldn’t give their work more credence
just because I like them better than others.
That’s the yes. What about the “No”?
The antireligion types who suggest that non-atheist scientists must
wall off part of their thinking when doing science, and likewise when
practicing religion, are basing that statement on their belief that
science and religion are fundamentally incompatible, that acceptance of
one requires the dismissal or (at least) compromise of the other. I
disagree with this statement. As I have said before, I view religion
(as expressed in a way that is compatible with the modern world) as
orthogonal to science.
Let me give a smaller example. I have been to scientific conferences
where I had a choice of talks or sessions to go to. Sometimes, I had to
choose between a session closely related to my own work on the one
hand, and a session where a friend was presenting on the other. I chose
to go see my friend present, because as a human being I like to support
my friends, and I like to see what they are doing. Was this an
ethically dubious scientific decision? No! Give me a break; I
certainly didn’t go to (nor would I have been able to go to) every
scientific conference that had talks closely related to my work,
sometimes for human reasons (I had classes to teach, a wedding to go to
in which I was the groom, etc.).
This is an example of not completely walling off a
non-scientific part of my humanity from me doing science.
If somebody is motivated because of their desire to understand God’s
creation to choose to study Cosmology over other fields, is that such a
terrible thing? If they become Intelligent Designers, then they have
made the mistake I outlined above: allowing their philosophical
preconceptions to bias their interpretation of their results. But
whatever it is that one finds important in life will influence
things you value, including choices you may make in what you pursue in
science. And there is absolutely nothing wrong with this, nor is this
evidence of bad science.
As for the walling off in the other direction: you absolutely must
not wall off your scientific good sense when contemplating your
religion. I know that the antireligious crowd like to assert loudly and
stridently that science is incompatible with religion, so any scientist
must be deluding himself if he’s not an atheist. That, however, is
simply untrue. Science and religion are orthogonal. If you are a
practicing scientist who walls off his science when contemplating
religion, you could end up like
href="http://scienceblogs.com/interactions/2007/02/science_is_not_just_a_game_1.php">this
fellow, a geologist whose PhD thesis was critically dependent on the
notion of a billions-of-year-old Earth, and yet who remains a
young-Earth creationist. This is an example of compartmentalization
leading to metastasized philosophical illness. Some will defend him
saying that his scientific results are all valid if he’s following the
right procedures of science. I don’t doubt that the antireligious types
think I’ve been doing basically the same thing if I’m doing any valid
science. But I assert to you strongly that I am not. I don’t see the
point in pursuing science if we don’t think we’re pursuing something
that is right.
There are forms of religion that are incompatible with the human
understanding that has come with the modern world. Young-earth
creationism is the most glaring example. It simply does not make
sense in the modern world for an informed person to believe that
the world is only 6,000 years old. I know there are some who do, but it
simply doesn’t make sense. We have overwhelming evidence to the
contrary. Walling off good scientific sense while contemplating
religion leads to bad religion, which in turn has bad social
consequences as people attempt to legislate education to teach science
that doesn’t conflict with that bad religion.
For religion to make sense in the modern world, it must always be
changing, adapting, as we learn more not only about the natural world
through science, but about what it means to be human through all of the
other creative endeavors that humans engage in. Many—
fundamentalists of both the religions and antireligious stripe—
like to insist that religion must be based on ancient writings and
dogmas, that for it to make any sense we must never alter or update our
views about theological truths. I have had creationists in my comments
assert that they can’t see how a Christian could believe in a
billions-of-years-old Earth… and I’ve had atheists comment (sometimes
politely, more often belligerently) that I shouldn’t be allowed to call
myself “Christian” because I don’t subscribe completely to a set of set
of doctrines decided upon by a
href="http://en.wikipedia.org/wiki/Nicene_Creed">committee of white
guys 1600 years ago. (Or, even more, to the interpretation of those
words promoted by today’s fundamentalist churches.) But this is not modern religion. Theology and religious studies are still going concerns… not just sociological studies about religion and the religious, but also study of the theology itself. Obviously it’s not a static thing inscribed in stone in the past; obviously it can still learn and advance like any other human endeavor.
I have described the proces of science as just the process of
careful, honest, and applied common sense. You have to be aware of any
philosophical preconceptions that might influence the interpretations of
your results, and you have to avoid letting these preconceptions bias
you as much as possible. This is the way in which one must
compartmentalize one’s science from one’s religion or other ideologies.
However, one should not compartmentalize away science while
contemplating religion. What’s more, one can be a whole human being,
accepting and thinking about the things we value in life (science,
religion, love, friendship, fun, beauty, etc.) without having to
compartmentalize them all away based on the narrow-minded view of some
strident and extreme ideologues who believe that various of these conceptss are so fundamentally
inconsistent as to require one to destroy the other.
