Perhaps
the theists among you will be inclined to ignore anything a heathen such as
myself might have to say about the traits attributed to the gods worshipped by
all those various cults humans have invented over the last several thousand years. Still, I think this is worth paying
attention to. Theists and atheists
alike have claimed scientific authority for their opposition positions on the
question of whether or not a god or many gods could exist, so closer
examination of this issue is warranted.
What
I intend to do here is to offer several definitions and traits of gods that
people actually believe in, and then discuss whether these gods may or may not
be compatible with a scientific understanding of the universe.
Let’s
begin.
1) God is love.
I’ve heard it more times than I can count. Theists will ask me if I believe in love, and if I answer in
the affirmative, they claim victory by defining their god as love. Well, let’s consider this a little
further.
First
of all, if you define god as “love,” you’ve already lost. Love is an emotion, not a being. If you want to call it god, you’re
welcome, but you lose any claims of the miraculous, any claims that this god
could exist as a real entity independent of the human mind, and all the stories
about this being that fill your cherished holy scriptures. The god that people actually worship is
not “love.” You may argue that
this god has an infinite capacity for love, and that’s fine--we can then have a
discussion about whether or not such a being is real--but saying “god is love”
is linguistic trickery, and not even very good linguistic trickery.
This
also raises an interesting point.
What is love, anyway? Well,
it’s an emotion, which means it is a product of the physical brain. What we call love has actually been
identified by psychologists as a series of emotions each governed by a set of
neurotransmitters (or brain chemicals) which evolved in such a way to make us
more likely to reproduce and raise viable offspring. We pass through stages of lust, attraction, and
attachment. Each of these are
produced by different neurotransmitters, and our conscious “minds” (whatever that word means!) perceive the whole
package as “falling in love.”
York
psychologist Professor Arthur Arun conducted an experiment in his research to
determine how people fall in love.
He had his subjects complete three tasks. First, find a complete stranger. Second, exchange intimate details about one another for a
period of approximately thirty minutes.
Finally, stare at one another’s eyes for four minutes without
speaking. After completing these
tasks, many of Arun’s subjects felt deeply attracted and two were later
married.
None
of this is to say that love is unimportant. Just because we understand what is happening to cause us to
feel emotion does not make the emotion less important. We know that we evolved to feel these
emotions for specific reasons, and we also know that for similar reasons, we
find these emotions to be extremely important to us. Love can be a great thing--just don’t assume it’s some sort
of mystical power, because it’s not.
It’s neurochemistry, just like all other emotions. Indeed, every conscious thought or
feeling we have boils down to nothing more than neurochemistry, and I think
that’s just wonderful. I just
don’t think most people want to think of their god as nothing more than
testosterone and dopamine.
2) God is the
universe. Again, if you want to define your god as the sum total of
everything in the universe, fine.
But the universe, contrary to what a bunch of new age buffoons want to
think, is not a conscious entity.
The universe is the result of a series of processes occurring in
accordance with natural law.
Again, that doesn’t make it less beautiful--quite the contrary!--but it
does mean it’s not the sort of god that people actually worship.
When
Einstein famously make remarks to “god” in his writings (perhaps most famously
his declaration that “God does not throw dice,” in response to Heisenberg’s
indeterminacy principle), he does not refer to any spiritual or conscious
entity. God is simply Einstein’s
poetic way of referring to the sum total of natural law, or the order of the
universe.
Bypassing
plenty of interesting (but ultimately useless) philosophy, we can say that yes,
the universe exists. But that
certainly does not make it a god.
With
those two bits of linguistic elasticity out of the way, we can begin to discuss
the character traits that people ascribe to the gods they actually do
worship. The gods we discuss here
are the theistic gods, and the ones whose followers are demonstrating
considerable influence in public policy, so this is where the discussion gets
really important. I’m going to
separate these gods out so that each represents only a single character trait,
but simply note that most people assume their god to possess some combination
of several (if not all) of the following traits. I separate them simply for ease of discussion, and without
altering the relevance or accuracy of the arguments.
3) God created
life/the diversity of life. These two related claims are separated by a
slash for a very important reason.
There is definitely a difference between creating life and being
responsible for biodiversity.
The
second of these questions is the easiest to tackle. Clearly a god who is responsible for biodiversity is
incompatible with known data. The
diversity of life is the product of evolution. Natural selection, which is defined as descent with heredity
or nonrandom survival of replicators, drives the evolutionary process, creating
the diversity of species we enjoy on our planet, each adapted to different
circumstances. If you disagree
with this, then sorry but you’re just dead wrong. While all science is tentative by design, evolution is as
firmly established as anything else in science, and is such a powerful theory
that it has implications in fields as diverse as agriculture, industry, and
medicine.
The
first question is a little more difficult, because the initial origin of the
first life (after which natural selection can handle the rest) is not fully
understood. However, though we
don’t yet know the precise process, all evidence suggests that life is a result
simply of chemistry occurring without any guiding hand under the correct
circumstances. Indeed, it may turn
out to not even be that rare an occurrence. There is considerable--though not yet anywhere near
conclusive--evidence of life (albeit microscopic) on other worlds.
There’s
still plenty of work to be done here, and we could certainly use some more good
biologists and chemists working on the problem to fill in what gaps still exist
in our knowledge. However, divine
intervention isn’t the answer. In
the case of biodiversity, divine intervention is directly contradicted by the
evidence. In the case of
abiogenesis (or the origin of life from nonliving matter--not to be confused
with the discredited notion of spontaneous generation), though the data are not
as conclusive, current evidence suggests a process devoid of conscious design.
4) God created the
universe. While we do not yet
have a complete picture of the formation of the universe, we now do know that
the formation of the universe is possible--without violating any physical
law--without the need to invoke a designer.
Thanks
to Einstein, we now understand that there is a mass-energy equivalency which
becomes key to our understanding of the formation of the universe. If mass and energy are the same thing
(and they are), we need only to understand how we got to a state of having
energy rather than not having energy…or do we? Actually, as it turns out, because there is also such a
thing as negative energy which precisely matches the total mass-energy of the
universe, the total mass-energy of the entire universe is exactly zero. I’ll say it again because it’s a bit of
a mind-bender unless you’re well-read in physics: the total energy of the
universe is precisely zero. Thus,
the formation of the universe does NOT violate the conservation of mass-energy.
Our
understanding of exactly how this all works out is a topic for another (much
longer) discussion. The important
point to remember here is that we now know that a godless universe does not
violate the laws of physics. This
has been an enormous leap forward in our understanding of our universe and, for
me, has proved to be the final nail in the coffin of belief in any sort of a
creator-god.
5) God fine-tuned the
universe for human life. This one boggles my mind. In addition to being mind-numbingly
self-centered and arrogant to assume that the entire universe (and you can
really have no conception of how big it really is) is designed with our pitiful
little species in mind, this claim seems self-evidently wrong.
For
one thing, it is clear that the universe predates humanity. That much is obvious. In fact, it predates us by more than 14
billion years. Clearly, then, the universe isn’t made
for us, but we are “made for” it.
Humans, like all species, are evolved to be well-adapted to our habitat.
Let
us also consider that, to date, we have found exactly one planet capable of
sustaining our kind of life.
Personally, I think it’s likely we’ll find life elsewhere. And I even think it’s likely that
there’s plenty of intelligent life in the universe (though less certain that
we’ll ever be able to cross the distances necessary to find it). Nevertheless, we know of only one place
habitable to humans. On this
planet, even, most locations are not habitable. Even our own planet is full of deep oceans, icy wastelands
and violent volcanoes, not to mention the biological threats to humanity that
come in the form of all the plants and animals that can kill us. The vast majority of the universe is
absolutely uninhabitable to any life at all. Even those places where life is possible, human life is still impossible. Clearly the universe is not fine-tuned
for us. We’re as well adapted to
it as we can be, but most of it is still completely hostile to us.
6) God performs
miracles. There is no reliable evidence to substantiate any claim of the
miraculous. Many have been
demonstrated to be frauds. For the
rest, the evidence simply isn’t there.
Considering how many people claim to experience the miraculous, however,
we should expect to see tons of such evidence. It would not be all that difficult to substantiate.
Furthermore,
any god capable of suspending the laws of physics is incompatible with our
understanding of what these laws of physics are. A law is different from a theory. While a theory is an explanatory framework of some series of
facts, a law does not do any explaining.
What it does is describe a relationship between two entities that always
occurs. Yes, all science is
tentative, but a miracle is a direct violation of what our current
understanding says is inviolable.
7) God endows people
with immortal souls. While this isn’t directly related to the question of
whether a god exists or not, it is peripherally related, and is important
enough an issue that it merits brief discussion.
The
simple fact of the matter is, we know as thoroughly as we can know anything
that there’s no such thing as a soul.
At one time in history, the human character or mind was attributed to
this invisible entity. We now know
that everything that happens in the “mind” is the result of a physical process
in the brain. Changes to the brain
result in changes to the mind or soul that would not occur if these processes
were not entirely controlled by neurochemistry.
Though
I would prefer otherwise to prevent misunderstanding, it’s still possible to
use the word “soul” in the way that we use “mind,” simply to describe these
emergent properties of the brain.
But in this case, it’s just a bit of poetic license. The god-granted immortal soul is just a
myth. When the brain stops
functioning, so does the mind or soul.
8) God dictates
morality. This one bothers me quite a lot, and on a number of different
levels. The idea comes in both a
hard and a soft format. In the
former, the theist claims that one cannot be moral without god. In the latter, they claim simply that
god is responsible for endowing us with a moral sense, or that our codes of
morality are based on the scriptures.
The
last of these is the first I’ll tackle.
It is true that some people have taken moral codes from the
scriptures. However, it is untrue
that modern codes of morality are scripturally based. There is an evolution of morality and scriptures were one
step in that evolution, but we have moved on. At the time the Bible was written (for just one example--the
same kinds of arguments apply to all scriptures), slavery was not considered an
immoral act. Indeed, the Bible
contains specific instructions regarding how slave-owners could treat their
property. We would no longer
consider this moral.
Indeed,
as morality changes over time, we can infer that morality is a social
construct. Social constructs can
be easily identified by two criteria: that they change over time and vary by
culture. Morality is just such a
phenomenon. While humans have
evolved a moral sense which seems more or less innate (I won’t go into all the
data on this particular topic of heated debate), the specific moral
prescriptions both vary by culture and change over time.
Morality
is a trait shared by all peoples, regardless of religion. Clearly one does not need gods to be
moral. Further, it has been argued
that secular morality is superior, particularly on two grounds. First, it is considered to be more
moral to do the right thing for its own sake, rather than because it’s what an
external force (in this case, a god, though the same argument could be made of
legal systems or any force) commands.
Second, secular morality does a better job of keeping up with the
changing moral zeitgeist. It’s not
the secularists, after all, who would deny marriage to homosexuals, ban
abortions, et cetera.
9) God communicates
through personal revelation. The evidence of this is nonexistent. It might be strong evidence if
someone’s claimed revelation revealed information they could not otherwise have
known, but this has never happened.
Further, we can now explain many of the visions of god that people have
which would once have been considered indicative of reality. As we’ve learned more and more about
the functioning of the human brain, more and more of these communications from
the divine are now understood to be simple hallucinations. The brain is a funny thing. It’s capable of comprehending the
universe, and can be fooled by the simplest illusion or imbalance.
In
addition, there’s an added problem regarding the character of a god who would
communicate with only some people but not the rest of us, which brings us to
our tenth and final trait.
10) God is
simultaneously omnipotent, omniscient, and omnibenevolent. The idea of an all-good, all-knowing,
and all-powerful god is both internally logically inconsistent and inconsistent
with the evidence.
First,
an internal inconsistency.
Omniscience and omnipotence are incompatible. For one to be omniscient, one must know the outcome of the
universe. To be omnipotent, one
must be able to change the outcome of the universe. This is a paradox that doesn’t interest me very much as an
atheist, but for which the theist can have no answer.
Now,
to omnipotence on its own. The
problem here is that if there is an omnipotent being, the laws of physics
should not be stable. The fact of
the matter is, the laws of nature remain consistent and are never observably
violated. This should not be the
case if there’s an omnipotent being out there somewhere.
Omniscience
actually isn’t exactly impossible.
It’s only impossible in the way it’s presented as a godly trait. If the universe is fundamentally
deterministic (and I go back and forth regarding whether I think it is or
not--I would say yes but quantum mechanics makes me question this), then it is
possible to imagine that a hyper-intelligent being could know the outcome of
the universe. Such a being is far
removed from anything humans can imagine, and the source of knowledge would not
be supernatural but advanced mathematics.
Practically speaking, there’s no such thing, but physics does allow for
at least some approximation of it.
Omnibenevolence
is a real problem because we’re supposed to believe in a god that does only
good, and yet plenty of bad shit happens.
It goes back to that old chestnut: Is god willing to prevent evil but
not able? Then he’s not
omnipotent. Is he able but not
willing? Then he’s evil. Is he neither willing nor able? Then
why call him god? Is he both
willing and able? Then whence
cometh evil? The fact of the
matter is, the world is a beautiful place and a horrible place. If there were a loving god, it should
just be the former and not the latter.
