(The following is a modified version of an essay I wrote for one of my philosophy classes a long time ago. Please excuse its sophomoric nature. The purpose of this post is to merely express my current beliefs, sophistication and extent of knowledge. I hope this will be a reference point from which I will be able to monitor how much I change or improve in the future.)
The Kalam Cosmological Argument
The Kalam cosmological argument (henceforth KCA). The recently popularized version of this argument was given by a popular contemporary philosopher named William Lane Craig. Dr. Craig’s version is as follows;
Does God Exist?
Cultures
across the world have traditionally converged on the matter of a belief in the
existence of God(s). The Gods had different names and characteristics; some believed in monotheism (such as Abrahamism) and others in polytheism (Greco-Roman religions) and furthermore, some conceptions even include a supernatural realm without an entity (Buddhism); but it
seemed as though the ancients universally treated the supernatural as a
required part of reality; perhaps in order to explain what they were incapable of
explaining. Moreover, great theologians and philosophers
over the past centuries have tried to place the belief in God on a platform of reason. With the likes of scholars such as Thomas Aquinas, one of the most
important questions they tried to answer is regarding the existence of God.
The question of God’s existence is a question about reality that everyone
ought to ponder over. Does God exist? Do we have any reasons to believe a God
exists? Many philosophers say yes. Many arguments have been proposed in favor
of God’s existence. A classical argument for God’s existence is the argument
from design which states that God’s existence is inferred from the complexities
of nature. A different argument that has earned both marvel and notoriety is
the ontological argument which concludes
that existence is in the very nature or definition of God. Another popular
argument is the first cause argument which states that there must have been a
first cause and this cause is God. This argument has received some recent
attention in its reformed version known as the Kalam cosmological argument
which infers God’s existence with the help of philosophical as well as modern scientific data regarding the origins of the Universe. However, the
soundness of these arguments are often questioned and debated and upon
analyzing the many arguments about God, it seems that disbelieving in the
existence of God is the most reasonable position to hold.
It is important to understand that
disbelieving in the existence of God is different from asserting that God does
not exist. This idea can be easily explained via an analogy. Imagine yourself
being approached by a stranger who claims that what everyone perceives as
reality is merely a computer simulation called the ‘Matrix’. He then begins to
give you a few reasons as to why he believes the perceived reality is not real. However, you
are not convinced by his reasons. You are able to cast doubt and question all
the arguments he produced. However, at the end of the day, you are also unable
to prove that reality is not merely the Matrix. It almost seems as though it
would be impossible to prove that the Matrix does not exist.
However, you realize that even though you cannot disprove the existence of the
Matrix, you find no reason to believe it actually exists. Therefore, the most
reasonable position would be to disbelieve in the existence of the Matrix.
Likewise, if one is not convinced by the reasons given for the existence of
God, then the most reasonable and intellectually honest position to hold would
be to disbelieve in the existence of God.
Thus, we carefully examine three of
the most popular arguments for God and they are the argument from design, the
ontological argument and the kalam cosmological argument for God’s existence.
Before examining these arguments, it is important to define God. For the purpose of the essay, the traditional Western conception of God is considered. The commonly
accepted definition is that God is the greatest conceivable being i.e. God is
omnipotent, omnibenevolent, omniscient, immaterial, eternal and the un-caused
creator of the universe. Let us now begin examining the arguments for God
starting with the argument from design.
The Design Argument
Premise 1) Artifacts that exhibit complexity are designed with intelligence.
The Design Argument
Premise 1) Artifacts that exhibit complexity are designed with intelligence.
Premise 2) The universe exhibits complexity.
Conclusion) Therefore, the Universe is designed with intelligence.
From this argument, a second
argument is produced in the following manner,
Premise 1) The Universe is intelligently designed.
Premise 2) If the Universe is
intelligently designed, then the universe was designed by God
Conclusion) Therefore, the Universe was designed by God
The important point to note is that that
the first argument is formally invalid. Notice that the first premise does not state that 'everything that exhibits complexity are designed with intelligence'. Rather, the first premise discusses the fact that all intelligently designed or man-made artifacts are designed with intelligence. The fact that all man-made artifacts
exhibit some level of complexity due to intelligent design does not logically
necessitate that all non man-made objects exhibiting complexity are the result
of intelligent design. In other words, the first premise fails to establish the implied but necessary notion that "Everything exhibiting complexity is designed with intelligence." A prominent example can be seen in the case of evolution
via natural selection where a combination of natural factors ranging from
random mutations, resources, predator-prey relationships, external environmental changes, adaptability etc are sufficient to
create complex biological systems. The example from biological evolution
invalidates the necessity for intelligence to produce complexity.
Another point to note is that the
first argument is one based on analogy to Human artifacts. The classic example
is that of William Paley’s watch-maker analogy. The idea is that if a watch
implies the existence of a watchmaker (even if one has no experience of who the
watchmaker is), then the universe implies the existence of a creator of the
universe (even if one cannot directly experience the creator or the creation).
The second argument follows the
first argument in stating that God is the intelligent designer of the universe.
In examining the argument, the first obvious doubt would be regarding the
strength of the analogy provided. Using Paley’s watchmaker example, should it necessarily
be the case that the existence of a universe implies a Creator of the universe
that same way a watch implies a watch maker? Perhaps we should examine why a
watch implies a watchmaker and analyze if the universe or nature fits the same
category as a watch. The main point to note is that the statement "a watch implies a watchmaker" is a posteriori knowledge that is one based on sensory experience (either of the person or through another person). Yet the analogy treats the statement as a priori knowledge even when such a claim is unjustified. Another point to note about the watch is that one can
physically experience a watchmaker making a watch. Anyone is capable of walking
into a factory and see a watch getting made. The same is not true of, for
example, mountains. Science would
tell us about the natural formation of mountains due to geological activity.
However, following Paley’s analogy, should it be the case that mountains were
individually designed the same way every watch was designed? In this case, the
God explanation seems to be redundant as it is parsimonious and sufficient to
accept the reason for the formation of mountains was due to the activity of
plate tectonics alone. Similarly, just as mountains do not necessarily need a mountain-maker,
why couldn't it be the case that a universe does not necessarily need a universe-creator?
The third point to note about the
watch-maker analogy is that the extent of the analogy is arbitrary. The analogy
states that a watch implies a watchmaker. But why stop the analogy there? Why
not the following? A watch implies a watchmaker which further implies that the
watchmaker had a material (human) cause. This would be against the definition of a God who is defined as immaterial
and uncaused.
A response to the third point would
be that one can easily imagine different kinds of designers (for example, alien
intelligence) that could be fundamentally different from humans. Thus it can be
argued that the watchmaker does not further imply that, for example, the
designer was human etc. It can be then be stated that what all designers would
have in common is a mind. Thus, the
proponents of the design argument can argue that the watchmaker further implies
only an immaterial mind which would
indeed solidify the God explanation. However, this theistic contention suffers from
a major flaw in that it is based on the presupposition of dualism which states
that the mind and a material body are distinct entities. Many advances in the
field of neuroscience seem to indicate that the mind could be a product of the
brain and not something distinct from a physical body. At the very least, an
atheist can demand evidence for the existence of a mind independent of a
material body. Thus we are again left with the initial criticism of the argument
from design i.e that a watchmaker implies a material agent as a cause and by this analogy, it would then follow
that a material agent created the universe. However, God is defined as immaterial and if an immaterial God did not create the universe then God as the
creator of the universe does not exist, then by definition God does not exist.
The Ontological Argument
The Ontological Argument
Having cast our doubts on the
argument from design let us now move on to the Ontological argument for God’s
existence. The ontological argument is perhaps the cleverest of all arguments
ever made for God. The argument intends to answer one of the most complex
questions regarding reality yet it remains deceptively simple. Bertrand
Russell, the famous atheist philosopher, states that “it is easier to feel
convinced that [the ontological argument] must be fallacious than it is to find
out precisely where the fallacy lies.” The ontological argument appears in
various forms. We will discuss two versions of this argument. The first version
attempts to establish the existence of God through the very definition of God.
The argument is as follows,
- If God does not exist, then God is not a perfect being.
- God is a perfect being
- Therefore God exists.
This version of the ontological
argument is formally valid and it relies on the concept of a perfect being
which is called God. The reasoning is that a perfect being is not perfect if it
does not exist but since a perfect being is perfect by definition, then the
perfect being has to exist. This existing perfect being is called God.
Two objections can be raised against
this argument. Firstly, premise 1 can be doubted by arguing that perfection
does not necessitate existence. For example, consider the concept of a perfect place where all humans are happy. If existence is necessitated by perfection, then
it would follow that such a perfect place where all humans are happy exists. Yet quite clearly, not all humans live on this perfect place (unless Earth is this perfect place) nor is it the case that all humans are happy (i.e. if Earth is the perfect place). Thus, it would follow via reductio ad absurdum that such a perfect place does not exist and furthermore it would follow that perfection does not entail existence. Moreover, such a line of reasoning can be
used to state that many other imaginary places and characters are real. Thus,
it can be argued existence is separate from the attribute of a subject.
Therefore, a critic may conclude that a perfect god only exists if he exists
just as a perfect place exists only if it exists.
Secondly, one may accuse the
argument of circular reasoning. A circular argument is one in which the
conclusion appears as one of the premises and a "clever" circular argument is one in which the conclusion appears "hidden" in the premises. If god is defined as being perfect and
perfection entails existence as one of its properties then, essentially god is
defined as existing. Therefore, in simplistic terms, argument can be restated
as “God exists because he is an existing being.” Thus one may argue that it
commits the fallacy of question begging.
That being the case, the ontological
argument from God’s definition is not very popular. The more commonly used form
of the ontological argument is as follows;
- It is greater to exist in the mind and reality, than mind alone.
- The greatest conceivable being exists in the mind and in reality.
- Therefore, the greatest conceivable being exists in reality.
Once again, this version of the ontological argument is formally valid.
If it is the case that existing in 'mind and reality' is greater than existing in the
'mind' alone then a being with the greatest conceivable attributes would have to exist in 'reality' because if such a being only existed in the 'mind' then one could conceive of a greater being i.e. one that exists in both 'mind and reality' and this would then be the greatest conceivable being.
The obvious objection to this version of the ontological argument is to question the first premise. Why should existing in 'reality and mind' be greater than 'mind' alone? The force of the argument is that an "existing being" is greater than a "non-existing being". One may ask why existence should be a greatness at all? The above discussion raises the following question; why is 'existence'
being treated as if it were a property? Immanuel Kant, a German
theistic philosopher, famously concluded that existence is not a property. This
is to say that "existence" is not a part of any objects nature but
rather it is a "state" independent of the nature of any object. Initially, a theist can answer such questions by listing the utility of existent beings. For example, consider Alexander Fleming, the discoverer of the antibiotic penicillin which proved to be one of the greatest advances in the history of medicine. For the sake of simplicity, assume that there were 3 factors that led Dr. Fleming to his discovery and let these factors be brilliance, knowledge and dedication. Now for a thought experiment, suppose that Alexander Fleming never existed in "reality"; then imagine a person named Fake Fleming with the same amount of brilliance, knowledge and dedication who, in your imagination, discovers penicillin and contributes to the world of medicine exactly as the actual Dr. Fleming did except for the fact this person only "exists" in one's mind. What is the difference between Alexander Fleming in the actual world and Fake Fleming in a possible world. The difference is that Fake Fleming, despite discovering penicillin and benefiting society in one's imagination, did not actually help anyone in "reality". In this sense, Alexander Fleming was definitely "greater" than Fake Fleming.
The mistake with such an objection here is that "utilitarian greatness" is conflated with "characteristic greatness". The "greatness" in the context of a scientist finding a cure is the result of benefiting the society. It was not, however, a characteristic "greatness" of the scientist. In relation to example above, Fake Fleming is supposed to have been imagined with all the characteristics of Alexander Fleming which entails that Fake Fleming is intrinsically as great as Alexander Fleming. One can further extend this scenario by stating the same amount of benefit that was reaped from Alexander Fleming's work in the actual world was also achieved in Fake Fleming's hypothetical world. With such an understanding, it become clear why we in the actual world would intuitively rank Alexander Fleming as greater. This is simply due to the case that utilitarian greatness is only measured in terms of what benefits existing beings i.e. 'us' who live in the actual world. There was however, no difference to be spotted in the characteristics of Alexander Fleming and Fake Fleming. As the above mentioned Kant famously stated, the 'thought of a stack of 100 coins' and the 'thought of an existing stack of 100 coins' are no different. Adding "existence" to the 'thought of a stack of coins' does not change its value.
Furthermore, it seems nonsensical to state anything at all, let alone God, "exists" in the 'mind' in the same manner anything exists in the actual world. When one thinks of a stack of coins, it is not the case that a stack of coins actually "exists" anywhere in the "mind". Rather, it is the case there is merely a thought of a stack of coins. Therefore, the argument fallaciously equivocates the word "exists" since they have different meanings when used in relation to the mind or reality. Thus, the first premise bases itself on a faulty comparison.

The Kalam Cosmological Argument
The Kalam cosmological argument (henceforth KCA). The recently popularized version of this argument was given by a popular contemporary philosopher named William Lane Craig. Dr. Craig’s version is as follows;
Premise 1) Anything that begins to exist has a cause.
Premise 2) The universe began to exist.
Conclusion) Therefore, the Universe has a cause.
Dr. Craig has provided sophisticated
and well researched evidences from modern cosmology to substantiate the KCA. In
order to perform true justice to Craig’s argument, one would need to examine
all of his points and research in detail. However, such an examination is
beyond the scope of this essay. Thus, we will only superficially examine the truth value of the premises of Craig's KCA.
The first premise states that
“anything that begins to exist has a cause.” Even though this premise seems initially
plausible, the meaning of the premise might not be as clear as it seems. For
instance, what exactly does it mean to say “an object begins to exist”. The
meaning given by Craig is that it means an initially non-existent object has
started to exist. Let us consider the example of a wooden table. A table
“beginning to exist” means that the table was once non-existent until it was
made by a carpenter. Here the carpenter is the cause of the table. In the same
line of reasoning, the KCA would say that God is the cause of the universe.
The second premise is more
sophisticated than the first one as it involves evidences and data from
contemporary cosmology that are fairly difficult for a layman to comprehend.
Nevertheless, here is the general idea that can be garnered about what modern
cosmology states about premise 2. The universe began about 13.7 billion years
ago by the expansion of space and time from what is called a point of
singularity. This event of initial expansion is called the ‘Big Bang’. KCA tries
to imply that God is the cause of the Big Bang. Craig’s reasoning for positing
God as the cause of the universe is as follows; since the universe was brought
into existence from non-existence, then whatever caused the universe (all of
matter, space and time) to exist must be outside of space and time i.e it should be immaterial
(since matter needs space). Only abstract numbers and minds are immaterial.
Numbers cannot consciously create anything therefore the cause of the universe
must be a conscious immaterial mind. This mind is then defined as God or the mind of God.
While examining the soundness of
these claims, we realize that KCA faces some of the same objections faced by
the argument from design. Unlike the argument from design which was based on an
analogy, the first premise of KCA is an inductively strong statement. We all
know inductively that any time a new object is made such as a watch or a car or
a book, it was caused to exist by an external agent. However, is this enough to
conclude that universe was created by an agent external to the universe? Let us
go back to the table analogy. Should it necessarily be the case that a God is
the cause of the universe the same way a carpenter is the cause of a table? Let
us now examine the strength of this analogy. What does the sentence, “A
carpenter caused a table to exist” mean? It does not mean that a carpenter was
able to create a table out of nothing. He needed other raw materials such as
wood and nails. The carpenter has merely arranged the wood and other existing materials in a specific shape.
We call anything of that shape, a table. This can be extended to other man-made
objects as well. Thus we can generalize inductively that human creators cannot
create anything out of nothing but he or she can only arrange ‘pre-existing’ matter into different
forms. If this is the case, then what does it mean to say that “God caused the
universe to exist”? Relying on inductive experience, it would then mean God could not cause the universe to
exist from nothing but God had to arrange pre-existing
matter in the form of the universe.
However, if the universe was formed
from pre-existing matter that existed outside of time (even though, it is not clear how this can be), then the God explanation
once again becomes redundant as it would be more parsimonious to assume the
universe exists due to some natural phenomenon acting on the uncaused pre-existing
matter. This can be written in the form of an argument called the Kalam cosmological argument for God’s non-existence and
it is as follows,
Premise 1) Anything that begins to exist was created from
pre-existing material
Premise 2) Universe began to exist.
Premise 3) Universe was created from pre-existing material
Premise 2) Universe began to exist.
Premise 3) Universe was created from pre-existing material
Premise 4) If God created the universe, then the universe was not created from pre-existing material
Conclusion) Therefore, God did not create the universe
The obvious theistic objection would
be regarding the first premise. They may point out that since God is omnipotent,
God can create something out of nothing. However, this objection faces two
criticisms. Firstly, one can make the accusation of special pleading; and if special pleading is valid in this case, then the same can also be employed by atheists with regard to KCA. An atheist could special
plead that everything except that
universe needs a cause and thereby rejecting the first premise of KCA.
Secondly, it is to be noted that the first premise of the new argument shares
the same inductive strength as that of the first premise of KCA. The first
premise of KCA is inductively strong because we do not have experience of
anything beginning to exist uncaused.
Likewise, the first premise of the new argument shares equal inductive strength because we do not have experience of anything beginning to exist from nothing
(i.e without pre-existing material). Thus this argument is as strong as KCA.
Moreover, recent ideas in cosmology such as the Multiverse theory would perhaps
be compatible with the idea that matter has always existed and that our
universe is one of many universes generated in the multiverse.
The next problem for KCA comes from
the idea that the cause of the universe must be immaterial and only a mind is
capable of doing so. Once again, this presupposes dualism which we have already
cast our doubt on while examining the Argument from design. Once again, an
atheist could demand the theist to demonstrate that a mind can exist
independent of a material body. If it is not possible for an immaterial mind to
exist then God could not have created the universe which entails that God does
not exist since there is no creator for the universe.
In conclusion, we can see that three of the most popular arguments for the existence of God can be questioned and
doubted. The argument from design is based on an analogy about the complexities
of human artifacts. Yet it is not very clear that this inference can be
extended to the universe on the larger scale. The ontological argument, which implies that "existence" is a property of God, is a deviously clever argument, however, it is the subject of various objections that weaken its claim to soundness. Most of all, there is not enough good reason to accept that "existence" is a property, let alone a greatness-enhancing property. The Kalam cosmological argument
was based on the intuitive idea that everything needs a cause for its
existence. However, it is once again not clear why this cause must be god or if
it is even possible for God to be the cause. Other arguments for God can be
subjected to similar form of skepticism. Since, convincing reasons for God’s
existence have not been produced; the most reasonable and intellectually honest
position to hold is the position of disbelief in God.
