Arguments Concerning God
"Do not believe in anything simply because you have
heard it. Do not believe in anything simply because it is spoken and rumored by
many. Do not believe in anything simply because it is found written in your
religious books. Do not believe in anything merely on the authority of your
teachers and elders. Do not believe in traditions because they have been handed
down for many generations. But after observation and analysis, when you find
that anything agrees with reason and is conducive to the good and benefit of
one and all, then accept it and live up to it." --Buddha
Blaise
Pascal, a 17th century mathematician, argued as follows:
1. Either I
can believe in God (and act accordingly) or I can choose not to.
2. If I
believe in God, and God exists, then my reward will be infinite (heaven).
3. If I
believe in God, and God does not exist, then there will be a small cost (waste
of time going to church, etc.).
4. On the
other hand, if I don’t believe in God, but God exists, then my punishment will
be infinite (hell).
5. And if I
don’t believe in God, and God doesn’t exist, then there will only be a small
benefit (not wasting my time going to church, etc.).
6.
Therefore, I am infinitely better off if I believe in God. I would be a fool not to believe.

Does the argument give us an epistemic reason
to believe in God?
What reason do we have for believing that God would
send us to heaven or hell depending on whether we believe in God or not? How do we know that God wouldn’t do exactly
the opposite, or not send us anywhere?
Reason: Believing in something on the basis of evidence.
In
other words, you believe something because you have reason to think it is true.
Faith: Believing in
something because you think it is important for you to believe it,
regardless of whether the belief is supported by evidence.
The
belief could be important for your psychological health, you might think the
belief is necessary in order to live an ethical life, or it might be important
for some other (non-epistemic) reason.
According
to public opinion polls, the vast majority of Americans (in excess of 90%)
report that they believe in God, although significantly fewer say they are
“certain” that God exists. The
percentage is much lower in some parts of the world (it is about 45% in
Germany, for example), but it is fair to say that a majority of people
in the world believe in a God of some kind.
Pantheism:
God = The Universe
It’s
a pretty safe bet that the universe exists, so pantheists aren’t going out on a
limb by proclaiming the existence of God.
In fact, pantheism really just amounts to giving a different name to the
universe.
Popular descriptions of God:
All powerful
(omnipotent)
All knowing (omniscient)
All good (benevolent)
Also:
The Greatest Being
The Perfect Being
God
as Creator is the most common and most important description.

Christianity,
Islam, and Judaism, as well as many “minor” religions believe in a personal God
who created the universe. (“Personal”
means “personlike”…God is said to have a mind, to take deliberate actions, and
have other properties common to persons).
Over 50% of the people on planet earth subscribe to one of these
religions. A personal God, while not
necessarily omnipotent and omniscient, would certainly have to be very powerful
and knowledgeable to be up to the task of creating the universe. Typically, a personal God is believed to be
morally good as well. Of course, not
all adherents of these major religions conceives of God in exactly the same
way…a certain amount of variety is to be expected.
Hindus
and Buddhists (which together comprise about 20% of humanity) typically do not
believe in a personal God. According to
Hinduism, God is something called “Brahman”, which is difficult to describe or
comprehend. Brahman is fundamental to
the nature of reality….a universal soul, or force that pervades everything and
of which each persons’ soul is related (all souls are eventually reunited in
Brahman, after many reincarnations).
The Hindu conception of God is probably what inspired George Lucas to
invent “The Force”, the deity like energy that is featured in the Star Wars
movies. Brahman has three major
aspects: Brahma (The Creator), Vishnu
(The Preserver), Shiva (The Destroyer).
(In the Star Wars fiction, the Jedi are preservers, while the Sith are
destroyers). Hinduism does
feature Brahma, the creator aspect, which does fit one of the major
descriptions of God described above.
However, the arguments discussed below are of very limited to relevance
to Hinduism, let alone Buddhism (which I won’t attempt to describe at all).
The Wonders of Nature. Nature contains many wonders:
Specifically, things that have many intricate parts which work together
in order to achieve various effects.
The effects would not be achieved were any of the intricate parts to
fail or if conditions were altered.
Examples--
The human eye
Other
organs, plants and animals
Ecosystems (both macro and
micro)
The planet earth itself, and
its ability to sustain life
The solar system
The Not-by-Chance Argument (PP, page 13)
(1) Either the wonders of
nature occurred randomly, by chance, or they are the product of intelligent
design.
(2) They
could not have occurred by chance.
(3)
Therefore, they are the product of intelligent design.
The Same-Evidence Argument (PP, page 14)
(1) We rightfully conclude that objects such as
watches are made by intelligent designers because they have parts that work
together to serve a purpose.
(2) We have
the same evidence that the universe was made by an intelligent designer: The universe is also composed of parts that
work together to serve a purpose.
(3)
Therefore, we are entitled to conclude that the universe was made by an
intelligent designer.
Assume that the arguments are sound. What can we conclude about the
designer? (Can we conclude that the
designer is omniscient, omnipotent, benevolent, perfect, etc.?) Can we conclude that there is one designer?
Regarding the Same-Evidence Argument: Do we really have the same evidence
regarding the origin of a watch and the origin of the universe? Are there some relevant differences between
the two cases?
Regarding the Not-by-Chance Argument: Does the first premise present all of the
plausible alternatives, or have one or more been left out?
(1) Organisms reproduce at a geometric
rate. This cannot be sustained
indefinitely, so each population eventually reaches a maximum size.
(2) It follows that a high percentage of organisms
must die before they are able to reproduce.
(3) There are two factors that determine which
organisms live to reproduce, and which do not:
(i) Random chance (some are just
unlucky)
(ii) Traits with differential fitness
(some have traits that make survival more likely)
(4) Organisms pass on their traits to their
descendants.
(5) Therefore, the traits that have more
survival value are more likely to be passed on and widely represented in future
generations, while other traits tend to be eliminated from the species.
(6) Over time, a species will be modified. When enough of these modifications have
accumulated, we call the result a new species.
(7) The fact that every species has evolved
through natural selection explains why they are well-adapted to their
environments.
3 conditions
for Natural Selection in a reproducing population
1. Variety of traits
2. Differential Fitness of traits
3. Heritability of traits
Add (limited)
mutation as a mechanism for causing new variety, and you get evolution
· The
theory of evolution is not an argument against the existence of God.
· But
it does undermine one of the main arguments for God (the Design
Argument).
· The
theory of evolution is compatible with the existence of God, but it is not
compatible with the claim that the existence and adaptation of species is due
directly to God’s design.
Objection 1. Evolution by natural selection cannot account for complex
structures, such as the eye. The reason
is that in order for an organ to evolve, the bundle of traits that make it up
must be advantageous at every stage—otherwise, they would not be selected for
and would be eliminated. But there is
no use for half an eye, or an eye missing any vital part. Therefore, it would have to evolve all at
once, which is impossible (mutation doesn’t work that way).
Reply, part 1:
Rachels, p. 20: “A bit of
anatomy may originally be preserved by natural selection because it serves a
different adaptive purpose than the one it eventually comes to serve”. (See Stephen J. Gould, “The Panda’s Thumb”)
Reply, part 2:
The intensification of function.
An eye does not evolve from half an eye, it evolves from a more
primitive eye. Rachels, p. 21: “All we have to imagine is that a nerve only
slightly sensitive to light confers on an organism some small advantage in the
competition for survival. Then we can
understand the establishment of the first rudimentary eye.”
Reading recommendation (not an assignment for the
class): Anything by Richard Dawkins,
especially The Blind Watchmaker.
Objection 2. Even if evolution were to account for speciation and the
formation of complex structures, it doesn’t explain where life came from in the
first place. There must have been some
species to start with in order for natural selection to work.
Reply, part 1:
Natural selection can work on things other than organisms. All that is required is that there be a
population of replicators (things that make copies of themselves) with some
source of variation in (heritable) traits that effect the likelihood of
successful replication. Once such
things exist, they can naturally evolve to become increasingly complex
(although only some offshoots will actually do this…it is important to realize
that most life on earth is relatively simple and microscopic). Thus, the problem is reduced to the question
of where the original replicators came from.
Reply, part 2:
It’s true that the theory of evolution cannot explain where the
first replicators came from…a different theory is needed for that. Most scientists believe that the first
replicators were RNA molecules (or perhaps something simpler) that arose
naturally in the oceans of primordial earth within the first billion years of
the planet’s existence. Research into
exactly how this happened is still at an early stage, but there has been progress. Here is a good (if somewhat technical) paper
that sums it up:
THE
ORIGIN OF LIFE ON THE EARTH.
Objection 3. Evolution does not explain why there is a planet suitable for
life in the first place. If any one of
a large number of conditions on earth were changed, life could not have
evolved. It is hard to believe this
could have happened by sheer chance.
Reply: If
you were to pick a planet in the universe at random, the likelihood of that
planet having life is very, very small.
But given that there are billions and billions of planets in the
universe, it is very likely that at least some of them would have the
conditions necessary for life. Earth
just happens to be one of them.
Compare: from the fact that
winning the lottery is very unlikely, it doesn’t follow that no one ever wins
the lottery.
The First Cause Argument (PP, page 23)
(1) Everything that exists must have a cause.
(2) The chain of causes cannot reach back indefinitely. At some point, we must come to a First
Cause.
(3) The First Cause we may call God.
Problem: The argument is self-contradictory. It says that everything has a cause, but then says that there
must be a First Cause (something that has no cause).
Another problem: Suppose that premise 1 is false, and that there is a First
Cause. Why should we call this
God? How do we know that it has any of
the features commonly attributed to God?
For all that the argument says, it could be the Big Bang.
(1) Everything that exists within the universe
is part of a vast system of causes and effects.
(2) But the universe itself requires an
explanation—why does it exist?
(3) The only plausible explanation is that the
cause of the universe is God.
(4) Therefore, to explain the existence of the
universe, it is reasonable to believe in God.
What
can we conclude about the nature of “God”, other than that “God” is the reason
the universe exists? (Can we be sure
that God is omnipotent, benevolent, etc.?)
If
the universe requires an explanation, then why doesn’t God also require an
explanation? On the other hand,, if God
doesn’t require an explanation, then why insist that the universe does?
If God is to be an
explanation of the existence of the universe, then we must have some idea of how God and the Universe are related (or else there is
really no explanation being offered).
So, here are some possibilities:
A. God Is the Universe (pantheism)
In that case, God is not:
(i) a being with thoughts
or feelings
(ii)
the creator
(iii)
omniscient or omnipotent
(iv)
benevolent
In short, there is no God. This is really a form of atheism.
B. God Created the Universe
The idea is that God created the universe much in
the way that people create things. That
is, God came up with a plan for the universe, then went ahead and made it.
But how is this possible?
1. The
Creator (God) is either in the universe or it isn’t.
2. If the
Creator is in the universe, then it must have created itself (since it created
the whole universe).
3. In
general, if A and B are things in the universe, and A created B, then A must
have existed before B existed.
4.
Therefore, if A created itself, then A must have existed before A
existed.
5. But
nothing can exist before it exists!
(Because it would have to exist and not exist at the same time)
6.
Therefore, it is impossible that the Creator is in the universe.
Modern
physics conceives of the universe as an object of (at least) four dimensions,
one of which is time. The four (or
more) dimensional whole is referred to as “spacetime”. One consequence of this is that there was
literally no time before the universe existed.
Since the universe includes all of time and space (by definition), it
doesn’t even make sense to talk about times or places outside of the universe.
Not
really a fair question, since the word ‘where’ presupposes a spacetime
location. But some will find it
tempting to suggest that nothing could exist that is not in spacetime. For now, we will simply reject this
suggestion as question-begging, and grant that non-spatiotemporal existence is
at least possible.
By
definition, nothing exists before the universe, so God couldn’t
create the universe as we normally conceive of creation. (For the same reason, God couldn’t “cause”
the universe to exist, in the usual sense of ‘cause’).
Moreover,
since God is not a temporal being, God could not have thought processes
or make plans (whatever thoughts or plans that God has would have to
exist eternally, all at once)
So,
If God didn’t create the universe (in ordinary sense of the word
‘create’), then in what way is the existence of the universe explained by God?
C: God Necessitated the Universe.
In other words, the existence of God is a sufficient condition for the
existence of the universe. If God
exists, then the universe has to exist as well.
Isn’t
this the same as saying that God created or caused the universe??
NO, because the relationship
is logical, not temporal.
Examples of sufficiency without causation:
The existence
of mountains is sufficient (and necessary) for the existence of valleys.
But the mountains do not exist before the
valleys, they come about simultaneously.
The existence
of the numbers two and three is sufficient (and necessary) for the existence of
the number five.
Again, one does not cause or create the other.
But
what is it about the nature of God that would guarantee the existence of the
universe?
One theory: God is a maximal
being, and as such, guarantees the existence of all possible things,
including our universe.
This suggests that there are infinitely many
different universes, all existing in different spatiotemporal realms. This may not be a bad consequence,
though. Some philosophers and
physicists have reached the same conclusion on independent grounds.
One drawback to this is that it is hard to reconcile
with the idea that God is good, because a maximal being would necessitate the
existence of all kinds of evil, as well as good. It seems to go more smoothly with the idea that God is nonmoral
(morally neutral).
Another
theory: God is benevolent, and so
necessitates the existence of the best of all possible worlds (our universe).
Problem:
This doesn’t seem to be the best of all possible worlds.
(We will return to this issue in our discussion of
The Problem of Evil).
“Ontological” arguments are
attempts to prove the existence of God from the concept of God. The most famous of these was given by Saint Anselm of Canterbury
(1033-1109).
1. We understand the concept of God: that than which nothing greater can be
thought.
2. Therefore, that than
which nothing greater can be thought exists as a concept.
3. If something exists merely as a concept, then it is not as
great as were it to exist in reality.
4. If (a) that than which
nothing greater can be thought does
not exist in reality, then (b) something greater than it can be thought.
5. (b) is false (because
it implies a contradiction)
6. Therefore, (a) is false.
[Modus Tollens 4,5]
7. In other words, that than which nothing greater can be
thought does exist in reality (God exists in reality).
Does the
Ontological Argument Prove Too Much?
1. We understand the concept of Islandia: the island than which none greater can be thought. [P]
2. Therefore, the island
than which none greater can be thought exists as a concept.
3. If something exists merely as a concept, then it is not as
great as were it to exist in reality.
4. If (a) the island than
which none greater can be thought does not exist in reality, then (b) an
island greater than it can be thought.
5. (b) is false (because
it implies a contradiction)
6. Therefore, (a) is false.
[Modus Tollens 4,5]
7. In other words, the
island than which none greater can be thought does exist in reality
(Islandia exists in reality).
Also
try:
The unicorn than which none greater
can be thought
The pile of diamonds than which none
greater can be thought
The living dinosaur than which none
greater can be thought
Etc.
Where
does the argument go wrong?
Premise 1 is suspect: Can we be sure that we understand the concept? Perhaps it contains a hidden
contradiction. (E.g. “the greatest number”)
Premise 2.
Here is the big problem.
The
concept of God exists ¹ God exists as a concept
If
the concept of X exists, this does not mean that X exists as a concept. That would mean that X really exists, but in
some special, conceptual way.
The
word ‘concept’ is ambiguous. The
“concept of X” can refer to either:
A. A mental representation of X (something that
exists in the mind)
B.
The property of being X (what Plato would call the Form of X)
In
neither case does the “concept of X” refer to X itself, existing in some
special way.
Consider:
1. If an 800 pound gorilla exists, then it
weighs 800 pounds.
2. Therefore, if an 800 pound gorilla exists
“as a concept”, then the concept weighs 800 pounds.
3. But concepts don’t weigh anything.
4. Therefore, an 800 pound gorilla doesn’t
exist “as a concept”.
Let’s
start with something familiar:
The concept of being a bachelor
implies being unmarried.
But
this just means:
If something has the property of being
a bachelor (in other words, if something is a bachelor), then it is
unmarried.
With
this in mind, consider the following claim:
The concept of God implies that God exists.
But
this just means:
If something has the property of being God
(in other words, if something is God), then it exists.
Compare:
The property of being a banana entails existence.
OR
If something is a banana, then it exists.
These
are equivalent to saying:
If something is a banana, then it is a banana.
It doesn’t follow that any bananas actually exist.
The
property of being a unicorn entails existence.
True!
(Even though no unicorns actually exist)
For
any kind of thing whatsoever, something couldn’t be that type of thing unless
it existed.
So,
it is important not to confuse the following two claims:
(i) The
property of being God entails existence.
(ii) If the
property of being God exists, then God exists.
(i)
is obviously true, once we understand what it means. To be successful, an ontological argument needs to prove (ii).
It
comes down to this. There are many
properties that have no instances (being a unicorn, being a planet made
entirely of rubber, being Superman, etc.)
At
first glance, it seems that being God could be one of these
properties. In other words, there could
be the property of being God (the concept of God) even though God
doesn’t exist.
An
ontological argument is supposed to prove otherwise—that being God
necessarily has an instance (God).
Assume
that:
1. God exists.
2. God is all-knowing.
3. God is all-powerful.
4. God is all-good.
BUT:
5. Nothing bad would exist, if there were
someone who knew about it, could do something about it, and was entirely
opposed to what is bad.
IT
FOLLOWS THAT:
6. Nothing bad exists.
7. But:
Bad things do exist.
CONTRADICTION!
______________________________________________
SO: Either God is not all-knowing, or God is not
all-powerful, God is not all-good, or God does not exist at all.
Is
evil an illusion? Perhaps things that seem
bad are really not; perhaps they are all part of God’s perfect plan that we
mere mortals cannot comprehend.
(Objection to premise 7)
BUT: If we are so radically mistaken about which things are bad (e.g.
genocide, torture, children dying of cancer) then all of our value judgments
are thrown into doubt. If we are
incapable of being able to tell when something is bad, then it is reasonable to
suspect that we are also incapable of being able to tell when something is
good. What basis would we have for
believing that anything (including God) is good? For that matter, how do we know right from wrong?
Okay,
maybe evil does exist, but God has a good reason for permitting
evil. We may never know what that
reason is, because we don’t know God’s plan and we can’t fully comprehend the
mind of God. (This is an objection to
premise 5)
Let’s grant that it is possible that God
would permit evil, because God might have some (unspecified) good reason for
doing so. If we grant this, then we are
rejecting premise 5. That is enough to
solve the logical Problem of Evil—God and evil are logically compatible,
at least as far as we know.
But just because something is possible doesn’t make
it true, or even likely. It is possible
that one of you will be struck by lightning tomorrow, but it’s very
improbable. Likewise, it is possible
that God has a good reason to permit evil, but on the face of it, it seems
doubtful. Unless some explanation is
forthcoming, the Problem of Evil is evidence against the existence of an all-good,
all-powerful God.
Some
Leading Ideas:
Problems:
Useless (and gratuitous) pains, like the pain of throat cancer that one is
helpless to do anything about. Harms
that don’t cause pain, like carbon monoxide poisoning.
Perhaps in a world without evil, people would not
know what evil is, and maybe they wouldn’t know the difference between good and
evil.
But that doesn’t mean that it would be a world
without good: in general, the fact that
you don’t know the difference between A and B doesn’t imply that there is no
difference, nor does it imply that neither exists. For example, there could be a world where nothing is white. No one would know what white is, but things
could still be black, and blue, and other colors. Is good and evil different somehow?
Problem:
There is way more evil than would be necessary for achieving an
appreciation of the good (isn’t there?)
Also:
Wouldn’t it have been nicer just to make humans so that they naturally
appreciate the good, without having to experience terrible forms of evil first?
Problem:
People are “punished” more or less at random, and usually not in
proportion to the amount of wrong they have done.
Think about this in relation to: Childhood diseases, genocide, innocent
victims of torture, rape, etc.
Earthquakes, tsunamis…
Some More (and better) Ideas:
Which
world is better?
(a) A world without humans in it, which would not contain any of the
bad things people do; but neither would it contain any of the results of human
consciousness, creativity, and virtue.
(b) A world with humans in it, which would include human wickedness
but also the good things that humanity brings with it.
If
you said, “(b)”, then you have agreed to a partial answer to the Problem of
Evil.
If finite, imperfect creatures are given free will
(the ability to make their own choices), some of their choices are bound to be
bad.
Isn’t it better to have a world in which we can be
free and make mistakes, rather than a world in which we can’t commit evil but
lack freedom?
However, even if human evil were a result of free
will, this wouldn’t get God off the hook, because there is still natural
evil. There are plenty of bad
things (e.g. diseases, natural disasters) that are not the result of free
will. This brings us to
Evil gets us off our duffs and motivates us to
improve ourselves and our world.
Without problems to overcome, we become slugs and our lives are not
worthwhile (even though we may experience lots of pleasure). The presence of evil forces us to develop moral
character, which is valuable in its own right. It also inspires us to take on worthwhile projects (such as the
creation of new technology) that would never have occurred to us otherwise.
Problem: “there is far more evil than is necessary for [developing
moral character]: There is stunning,
overpowering evil that crushes the life out of people. If we already have AIDS, muscular dystrophy,
cerebral palsy, and spina bifida, why do we need Ebola as well? If the people of Guatemala are already poor
and hungry, why do they need an earthquake on top of it?” (Problems
from Philosophy, p. 39)
One
response to the Problem of Evil is to concede that the world contains many bad
things, but maintain that all of the other possible worlds are even worse. That is, God created the best possible world
of the alternatives available. A
variant on this response is to claim that there was just one possible world
–this one—and God decided to create it because it was better than nothing.
But it is hard to believe that there
weren’t any better alternatives.
Isn’t it??
Of
course, depending on what you think happens to us when we die, evil may or may
not seem like a pressing problem. If
you think that we go to heaven, then the evil on earth doesn’t seem nearly as
bad as it would be otherwise. It is
just a temporary blip or “aberration in human history” (as Peter van Inwagen
put it). But is there any (epistemic)
reason to believe in heaven?
