The Existence of God

[1995 Intro] In August of 1993, my friend, Jeff McCain, and I participated in a debate at the Orange County Regional Gathering of Mensa. The topic was the existence of God. Jeff and I took the affirmative position, an Agnostic and an Atheist took the negative position. Jeff presented an inductive, historical argument for the existence of God, and I presented a deductive argument for the existence of God. As I was developing the material for the debate, I began testing it by arguing some points with a number of Atheists and Agnostics on CompuServe, a service that connects thousands of computer users via telephone. To my surprise, in every case, my opponent either outright reject logic, or tenaciously held on to a logical fallacy, even after knowing it was a fallacy.

[2000 addition] The version you have before you is an updated version of the argument. There are more diagrams and charts, and several new sections have been added to answer objections that I have encountered in my debates. I hope you will enjoy this new version. My thanks to all who took the time and thought to enter into debate with me.

[2008 addition] What's new in this edition of "The Existence of God?" I have completely re-edited the text to make it more readable. I have also reworked the graphs and charts to make them clear and easier to understand.

In discussing this argument with many unbelievers since 1995, I continue to find that the only way the unbeliever has been able to circumvent the conclusion is either to commit a obvious logical fallacy or simply misrepresent the conclusion. Some of those misrepresentations have been honest misunderstandings of the implications of the conclusion, others were intentional. For those who honestly misunderstood the implication, I am adding a new appendix to try and clear this up.

Let's Begin -

A common phrase that I hear from would be philosophers is: "No one can prove that God exists." This is usually followed by someone else saying: "Oh yeah! Well, no one can prove He doesn't!" This is not a very well thought out assertion by the unbeliever, but the response of the believer is even worse!

For the unbeliever to make the assertion "No one can prove that God exists" requires one of two possibilities to be true on the unbeliever's part.

1) The unbeliever has examined and found all possible arguments (inductive and deductive) for the existence of God that have ever been offered and could ever be offered to be wanting,

2) The unbeliever has some way of knowing without examining any arguments that it is not possible to prove that God exists.

I personally have never found an unbeliever who has claimed to have examined all possible arguments for the existence of God, nor have I found one who could give an a priori reason why it is impossible to prove that God exists. This would not mean that one of these two possibilities could not be the case; but the fact that I am offering a logically valid demonstration that God does exist, would suggest that neither is the case.

Let's go back to the believer. The burden of proof does fall to the person making the affirmative statement. This means that the person stating that God exists must show his position to be true. The statement by the believer, " No one can prove God doesn't exist," is quite unacceptable. In other words, he must show that his position accurately reflects reality; that there is a correspondence between what the believer says, and what really is the case. Luckily for the believer, we can demonstrate that God does exist. The person who believes in God does not have to use such lame comebacks as "Nobody can prove that God doesn't exist.” However, the believer must take the time to study and research the issues that are being discussed. After you finish studying this paper, when someone says: "You can't demonstrate that God exists!", you can respond: "Sure I can. Let me show you!"

Absolute certainty -

Throughout history theologians and philosophers have presented cosmological, or causal arguments for the existence of God. Such well known names as St. Augustine (5th cent. AD), Rene Descartes (17th cent. AD), and Norman Geisler (21th Cent. AD), as well as many others, hold to the logical validity of such arguments. The advantage that Augustine, Descartes, and Geisler have is that they start from a point of certainty. After this they went into different directions. We will also start with these thinkers, and then we will go our separate way.

The point of certainty we will begin with is our self. Rene Descartes, the French, rationalist, philosopher is famous for the expression "I think, therefore I am." Although he never put it in those exact words, the thought can be found is his book "The Meditations" (I suggest reading at least the first three chapters of "The Meditations"). Descartes' idea is that this expression is the first thing that we can know with certainty. Briefly, his argument runs something like this: Let us take a philosophical journey. We will only affirm as true everything that we can know with certitude. Everything else we will doubt, until we can build a case based upon the thing(s) we can know for certain. We should doubt our senses; for our senses may deceive us, as with optical illusions. We should doubt our idea of the world around us, for even the idea of our own bodies may be false, as in a dream. But, the one thing we can't doubt is that we are doubting; for if we doubt that, we are still doubting. And if you are doubting, then you are thinking; for doubting is thinking. If you are thinking you must exist; for only existing beings can think.

Another way of putting it is: If you can say "I exist," then you know with certainty that you exist, for you must exist to state "I exist." If one does not exist, then that person would not be around to make the statement. Norman Geisler calls this statement an "existentially undeniable" statement (See Geisler's "Philosophy of Religion"). Even if a person tries to deny his own existence, it can easily be proven that their denial is false. The very denial creates a contradiction. For the person must exist to deny that the person exists. If the person did not exist, then the person wouldn't be around to make the denial. So, we are forced to a position of certainty. The statement "I exist," is necessarily true every time I uttered it. The only other alternative is to reject logic. The reason is that this premise is firmly grounded in the law of non-contradiction. Without this law no communication would be possible. Without this law there is no meaning at all. A logician would define this law by saying: 'A' cannot equal non-'A'. That is to say that something cannot be both wet and dry, in the same way, at the same time, in the same sense. Therefore, I cannot exist and not exist in the same way, at the same time, in the same sense. It is this basic law that must be rejected in order to reject our premise, and that leads to absurdity.

We have reached a point of certainty: I exist. If I exist, then something exists, for I fall into the category of something.

Here is our starting point, our first and undeniable premise:

Something exists.

I also ask, for the sake of argument and available space, that you grant something that you probably already affirm as true: That the universe around us also exists. That is our dimensions of time and space, and energy and matter, and all that are inherent to them. If you really have a problem with this, please write to me, and I will be happy to discuss it with you individually. Due to the limited space we have, I will ask for your indulgence.

So, here we are with something that exists.

Let's take a moment to diagram what we have agreed on.

Diagram 1.1

In the above diagram we see the category of everything that exists. In that category we see the two "some things" that we have agreed upon existing: “I” and “the universe”, and actually, I am part of the universe. At this point in the argument this is all that we know.

Where do we go from here? -

The next question that comes to mind is: Given that something exists now, did something always exist? We may also ask whether we can know the answer?

Fortunately, there are a limited number of explanations, and we can readily exclude several of them. Here is a list of all possible explanations for this something that exists:

1) Something always existed. In other words, either this something (the universe) always existed, or there was something else that always existed from which this something is derived.

2) There was a point when nothing existed.

Let's begin a chart that will help us visualize the relationship of the option.

CHART 1.1

We have set up what is known in logic as a disjunct. That means that there are two options available, and if one is false, then the other is necessarily true.

Allow me to digress for a moment to explain how it works.

Let's say that you and your friend Fred are going to play a little game. You have a penny and Fred has a quarter. These two coins are the only coins in the room. The way to play the game is: First, you turn your back. Next, Fred places one coin in his pants pocket, and the other in his hand, and then closes his hand. The object is for you to guess which coin is in his hand. (You must lead a very dull life if you are playing this game). So, with this being done, you turn and are about to make your guess when you notice the edge of the quarter protruding from Fred's pants pocket. Given that there are two and only two coins in the room, you have disproven that the coin in Fred's hand is the quarter. Therefore, you conclude that the coin in Fred's hand is necessarily (meaning: it must be) the penny. You are right.

If we were to write it out long hand, it would go something like this:

1) Either the Penny or the Quarter is in Fred's hand.

2) It's not the Quarter (I see that in his pocket).

3) Therefore, it's the Penny in his hand.

In logic notation it would look something like this:

Let P = Penny, Let Q = Quarter

1) P or Q (Premise)

2) Not Q (Premise)

3) Therefore P (Conclusion)

The upshot of all this is, if we can demonstrate one of the options in our disjunct to be false, then we know that the other option is true.

To make matters more interesting there are three options that come under the leg of "a point when there was non-existence":

a) Everything is an illusion, and nothing really exists.

b) Something created itself. The "something" is self-caused.

c) Something that now exists is derived, or caused, or came from nonexistence (i.e. something came from nothing).

Let's add these to our chart:

CHART 1.2

Let's examine "a point when there was non-existence," and its three options first.

Option (a) is easy to exclude as a real possibility. Option (a) says that nothing exists; that everything is an illusion. We have already determined that something exists, and we know that to be undeniably true. If something exists, then everything cannot be an illusion. But, for the sake of argument, let's assume that everything is an illusion. Wouldn't something have to exist to be having an illusion? Non-existence can't have illusions, only something that exists can have an illusion. Not only that, but the something having the illusion must be a cognitive something. So this possibility is self contradictory. It is logically impossible. Scratch the first one.

Option (b) asserts that something (this something - our universe, or perhaps something else from which this universe is derived) created itself. However, in order to create itself, it would have to be prior to its own existence. In other words it would have to be before it was; it would have to be, and not be, at the same time, and in the same sense. This is a flat out violation of the law of non-contradiction. A logical contradiction forces us to reject this option.

Option (c) says that something is derived from nothing. Let's define 'Nothing.' Nothing is what we find when we look into an empty cookie jar, there is nothing there, or no - thing there. By nothing we mean non-existence, or a complete lack of all attributes: No color, no shape, no size, no substance whatsoever, no attributes at all. If something could come from nothing, this nothing would have to at least have the attribute of being able to have something come from it. If nothing has that attribute, nothing is not 'nothing'. This is because the definition of 'nothing' is a complete lack of ALL attributes, and that which we are calling 'nothing' would have an attribute. The person who claims that something can come from nothing is equivocating on the terms. That person is using the same term in two different ways. The word 'nothing' means one thing at the beginning of the argument (it means a complete lack of all attributes), later it means something else (it means something with at least one attribute). In other words this person is cheating us with a semantic trick. But, we will not be fooled. Thus this third option fails, and with it so does the entire point.

Given our above inferences, let's see what conclusion we can draw:

1) If there ever was a point when there was nothing (no existence) and as we have already seen there would be no way to get something from nothing, then there would be nothing now.

2) There is something now.

3) Therefore, there never was a point when there was nothing (no existence).

Our conclusion is just another way of stating the second point of our disjunct: Something always existed.

By examining our conclusion a little closer we are also able to derive additional information from it. If something always existed, then it does not have a cause that brought it into existence (if it did have a cause, then it did not always exist). If this something had no cause, it is uncaused. If it is uncaused, it is infinite in its existence. These are some things that can be readily deduced, or unpacked from the term "always existed." It may not be all that we may know about that which always exists, but it does give us enough information to continue our quest. We now know that there is something that exists that has always existed, that is uncaused, and infinite in its existence. There is nothing inherently contradictory about something always existing. It is philosophically sound. In fact it is held by most of the worlds cosmologies, including Naturalism. The traditional Naturalistic cosmology maintains that the universe is, in some way or another, the always existing something from which anything and everything else is derived. Theism (Christianity, Judaism, and Islam) also maintains that there is an always existent. The difference is that the Theist maintains that the always existent is external to, or outside of, or transcendent to the universe in which we find ourselves, yet this original being can somehow still directly work inside the derived universe.

Let's add the always existent something to our diagram:

Diagram 1.2

We now know that the membership of the category of "Everything" includes The universe, and I (as part of the universe), and a subcategory of "Always existed." As stated above it is possible that the universe belongs to the category of "Always existed." At this point we do not know that to be the case. So, we leave it outside the category until we can determine if it belongs there.

Is the universe the always existent? -

Given that something has always existed, then either this universe has always existed, or it is not. Again, we have set up a disjunct.

CHART 1.3

If we can prove the leg that asserts "The universe has always existed" is false, then we have demonstrated that the other leg is true (again by disjunctive syllogism).

The attribute of 'always existent being' that we will focus on is infinity. As we discussed above, an always existent being would have to be infinite in its existence. Since the attribute of infinity is inherent to always existing, if we can demonstrate that the universe does not have this attribute, then we have demonstrated that the universe does not fall into the category of "Always existed."

There are three possibilities that are offered under the leg "The universe has always existed," :

1) It is possible that the substance, or stuff, or being of this universe is infinite in existence.

2) It is possible that there was an infinite regress of finite events.

3) It is possible that the universe existed in some form prior to the first motion event, outside of a dimension of time, and in a completely static condition.

If we can demonstrate that these three possibilities are false, then we have demonstrated that the leg is false. As we will see, these three cover all possibilities.

Let's add the three possibilities for an always existing universe to the chart:

CHART 1.4

Let's examine the first two historical options available under this leg. The first one says that the nature, or stuff, or substance of this universe is infinite; it always existed. The changes we see are changes in appearance not in substance. The second option says that the nature, or stuff of the universe is finite, but there was an infinite regress of connected events. Although, no thing or event could be considered infinite in itself, the universe as a whole would have always existed though this infinite, endless chain of cause and effect events.

These two views are different in fundamental points, but they do share one point that is vulnerable to criticism, and shows them to be false. Both views maintain that an infinite number of events have preceded the present event, the event we are experiencing right now. They say that an infinite series of events that stretch out into the past has been transversed or crossed to bring us to the current event we are now experiencing. If we can disprove this point, then both options are shown to be false.

The above position is vulnerable when it claims that an infinite number of events have been completely traversed. In other words, all members of the set we can call `the past events' have been crossed, and there are no events that can be called `past events' that have not been crossed. The position also maintains that there is no beginning to the series, thus the claim that the series is infinite.

To show the problem let's try a little theoretical experiment. Let's say we can reverse the logical order of events. So, we would begin going backward, crossing all events in the logical order except reversed.

The infinite universe models say that all past events have been traversed coming forward. So, we should be able to transverse all events going backwards. After all, there are no more events going backward, than are coming forward; there are the exact same number of events. But, if we can transverse all past events going backwards, we will have come to a point when there are no more events to cross. Thus, all events would be traversed. If all events have been traversed going backwards, and no events remain to be traversed, then we will have come to an end. If we come to an end, then the series is finite.You see, an end going backward would be a beginning coming forward, and if it had a beginning it must be finite. If it is finite it is not infinite.

What if we never get to an end going backwards? It would mean that all past events could not be traversed; and if all past events cannot be traversed going backwards, then they could not be traversed coming forwards. The same number of events are involved. If the series of events could not be traversed coming forward, then we would never be able to get to the current event we are experiencing right now. Yet, we are at the present event. Therefore, there are not an infinite number of events.

To summarize: If all past events could be traversed, then the past is not infinite. If the past is infinite then all past events could not be traversed to get us to the present event. Since the latter is patently false (we are at the current event), and the former denies the main premise of the infinite universe, which makes the proposition false, we can conclude that the two options that maintain an infinite series of past events are both false.

This brings us to the third option. It goes something like this: The universe that is currently in motion existed in some form logically prior to it's being in motion. At that point it was in a state absolutely static (without motion, or event) and absolutely timeless (without a dimension of time).

This option tries to avoid the error of attempting to traverse an actual infinite series of events. If there were no events and no time prior to the first motion event (presumably the big bang), it would be possible for the universe to be placed in the category of "always existed." This is because it could have existed without a beginning, and prior to the first motion event.

For the above to be a real possibility the following two premises must both be possible at the same time.

1) There was a point logically prior to the first event.

2) Whatever form the universe was in, it was absolutely static and timeless prior to the first event.

Let's examine the proposed first event a little more carefully and see what we can deduce given the premises.

There are three possibilities concerning any event. Either an event is necessary (which means it must happen, and cannot not happen), the event is contingent (it can happen or not happen depending on conditions), or the event is impossible (it cannot happen).

Let's say that given the above scenario the first event was contingent. There would be a point where the conditions needed for the first event were not present, so there would be no first event until the conditions came about for the first event. This gives us the "eternal" point prior to the first event that is suggested. But, this means that conditions would have to change in some way, so that the conditions needed for the first event could come about. But, this change would be an event in itself. So, it would be necessary to have an event precede the first event. This would mean that the first event is not the "first event." It also would deny that the universe was static prior to the "first event." The idea that this first event is contingent allows for premise 1, but denies premise 2.

Let's say that the first event was necessary. This would mean that if the first event could occur, it must occur. If all conditions needed for the first event were always present and there was no contingency, then the event would occur. This would save us from needing an event preceding our first event. However, If all conditions necessary for the first event were present, the event would have occurred without a point logically prior to it, for there would be no point logically prior such that the conditions for the first event were not present. This denies premise 1.

So, we see that given the above scenario, the first event is neither contingent, nor necessary. Therefore, it is an impossible event, given the premises. Since the universe is here, we must conclude that this third option is false.

We may derive something else from the fall of the three above options: Any other attempt to maintain that the universe always existed would have to present a scenario such that the universe could not be always in motion, nor be motionless at some prior point. Given the third law of logic, the law of excluded middle, there is no possibility of any other rational scenario proposing an always existent universe.

Since the three options available to the leg that maintains that the universe has always existed are shown to be false, the leg itself is shown false. If this leg is false, then the other leg of the disjunct must be true (via disjunctive syllogism). The leg we find to be true is that this universe has not always existed.

Although we have found that this universe did not always exist, we are still stuck with the fact that there is something in the category of "always existed." We also know that this `something' is infinite, and uncaused. The philosophical term for an actual always existent that is other than our universe is 'transcendent.' This argument also shows that if the universe is not infinite,it had a beginning, it is finite. If it is finite, then it is derived. That means it had to come from something else. For, as we have already seen, something cannot come from nothing.

So, here is what we have learned through our discussion:

1: Since something exists, something has always existed.

2: The something that has always existed is uncaused, infinite in its existence.

3: This always existing something is transcendent to our universe (a universe that did not always exist, and is derived).

Our final version of chart 1 now looks like this:

CHART 1.5

Although minimally so, isn't the term 'God' consistent with what we mean when we talk about an infinite, uncaused, always existent, that is transcendent to our finite, derived (created) universe?

Is this argument a good argument?-

First, in examining the argument we see that it follows standard disjunctive syllogisms, nothing fancy, just straight forward deductions. The form is a valid form. Which means that the form of the argument will yield a true conclusion provided all the premises are true. Thus, we say, the conclusion follows necessarily.

Second, we must examine the truth of the premises. The argument unfolds by examining the possibilities that come from unpacking an existentially undeniable premise ("I exist"). By `unpacking' I mean finding the necessary implications of the idea. For instance, if I exist, then it necessarily follows that something exists. If I know what I mean by `I' and I know what I mean by `something,' then I know for certain that if I exist, then something exists. I unpacked `something exists' from the statement `I exist.' Where there was more than one possibility unpacked, each was examined logically, and those that did not stand the examination were discarded, leaving those that were shown logically to be the case. In other words the premises used to demonstrate that God exists are true premises.

Therefore, since the argument is valid, and the premises are true, the conclusion yielded is a true conclusion. It is a conclusion that accurately describes reality.

A new objection -

Even though the argument is sound, there have been some attempts to get around the implication that God does exist. Allow me to share this latest attempt in the words from a gentleman whom I debated on this point: "What Mr. Lenardos has not accounted for is that in addition to being uncaused, always existent, transcendent, etc., `God' is almost universally understood to be a conscious, volitional being. From this it follows that no item picked out by the term `God' could lack these properties and still be God." Here are a few examples of quotes from modern day Atheist writers that were presented to me in that recent discussion:

From Philosopher Paul Edwards:

"It has frequently been pointed out that even if this argument (the classical causal argument) were sound it would not establish the existence of God. It would not show that the first cause is all-powerful or all-good or that it is in any sense personal. Defenders of the causal argument usually concede this and insist that the argument is not in itself meant to prove the existence of God....Supplementary arguments are required to show that the first cause must have attributes assigned to the deity." (From his article in The Rationalist Annual, 1959)

From William Rowe:

"(I)t might be objected that even if Aquinas' arguments do prove beyond doubt the existence of an unchanging changer, an uncaused cause, and a being that could not have failed to exist, the arguments fail to prove the existence of the theistic God." (Philosophy of Religion, Wadsworth Publishing Co., 1978)

Apparently these men, and there are others who follow them, feel it is necessary to demonstrate personality to demonstrate that what we have in a real always existing, uncaused, infinite that is transcendent to our finite, caused, derived universe can be termed as "God." The question is not whether God is a personal, active, volitional, conscious being, but rather, is it necessary to demonstrate that the always existent that does exist has these qualities in order to refer to it(?) as God?

I personally believe that God is personal. I don't believe that the demonstration of personality is needed to show that the always existent is God. You will note that although my argument does not demonstrate that the always existent is personal, the argument in no way denies that the always existent is personal. At this point the question is open.

This objection seems to me as nothing more than a last ditch effort to keep from having to admit the obvious. The idea that one must either demonstrate personality, or one cannot refer to the always existent as "God" is absurd. One reason is that there are several religions and philosophies that assert an impersonal God. It is not true that volition, action, consciousness, i.e., personality is universally held. Here are just a couple of examples:

1) Hinduism. The ultimate being (God) in Hinduism is Brahman. Here is what John B. Noss, author of "Man's Religions", has to say concerning Brahman in the Hindu writings: "Some treatises, the earlier ones, regularly refer to Brahman as a neuter something, without motion or feeling, the impersonal matrix from which the universe has issued and to which it will in time return. This It, this One Thing, is the substratum of everything." Further reading in the Upanishads (sacred Hindu writings) reveal that there is a personal form of Brahman (called the formed) and an impersonal form (called the formless). However, it is the impersonal that is the ultimate and real: "There are, assuredly, two forms of Brahman: the formed and the formless. Now that which is formed is unreal; that which is formless is real" (from "Maitri Upanishad"). So we find that the "real" is the impersonal. On further reading we also find that this "formless" and real is also actionless.

2) Plotinus. Plotinus had a huge neo-platonic following in the third century A.D. This next quotation is from Fredrick Copleston's "A History of Philosophy." It is about Plotinus' concept of God: "God is absolutely transcendent: He is the One, beyond all thought and all being... God is accordingly THE GOOD rather than "good." Moreover, we can legitimately ascribe to the One neither thought nor will nor activity."

3) Furthermore, we find that not even Theists historically believed that demonstrating personality was necessary to show that God exists. Such as Thomas Aquinas, Anselm, Descartes, Leibniz, and many others offered arguments for the existence of God that did not include personality as a criteria for demonstrating that God existed. Assuredly, all of them offered other arguments at different points that God is a personal being, but they did not find it necessary to offer an argument for personality to demonstrate that God existed. So we find that from historical, philosophical, religious, and theistic stand points, it is not necessary to demonstrate that God is personal, to demonstrate that God does exist. Allow me to offer a list of just a few of the philosophers who argued for the existence of God without an inherent argument for personality in the argument presented:

Plato (see "Laws" and "Phaedrus")

Aristotle (see "Metaphysics")

Anselm (see "Prologion" and "Monologion")

Alfarabi (for easy references for this and the next see "A History of Medieval Philosophy" by Armand A. Maurer)

Avicenna

Thomas Aquinas (see "Summa Theologica")

John Duns Scotus (see "Philosophical Writings" trans. Allan B. Wolter)

Rene Descartes (see "Meditations" ch.5)

Leibniz (see "Monadology")

Spinoza (see "Ethics")

Richard Taylor (see "The Cosmological Argument")

Charles Hartshorne (see "The Ontological Argument")

N. Malcolm (see "The Ontological Argument")

Here we have a wide range of philosophers from many different viewpoints. Represented are Dualists, Pantheists, Panentheists, Muslims, and Christians.

The meaning of a term can be drawn from its common usage within a community. The community that deals with the type of argument I have given is the philosophical/religious community. The common usage within this community for the last 2500 years refers to an infinite, uncaused, always existent which is transcendent to our finite, derived, caused universe as God. The conjunction of the above examples demonstrate that the premise that says it is necessary to show personality before we may refer to the always existent as "God" is false.

Last thoughts -

The argument I have given rest firmly and solidly on the laws of logic; in other words, rational thought. If someone would like to get around this argument there is only one way to do it: simply reject rational thought. You see, at the very beginning of the argument we had to make a choice: If we would deal with our topic rationally, or irrationally. If we chose the irrational, my argument is cut off at the root. I can't even make my first point, because all communication assumes rational thought. If, however, we chose to deal with the subject rationally, then the conclusion is clear: God exists!

You may find some who don't mind taking the irrational route when dealing with the existence of God. But, there can be no real reason to reject rational thought when it concerns God, and accept it in other areas. It is the same rational thought that tells a person to chew on the steak, and not the steak knife. So, if a person would be consistent in really giving up rational thought, it would be a toss up as to whether the person chews on the edge of the knife, or the steak presented on the plate. But, since we find few people who reject the existence of God, who are chewing on steak knives, we must assume that either they have not examined this argument, or they are selectively rejecting the argument despite its validity, and soundness. Each person must choose the way he will go. My only problem is with the person who rejects the argument and insists he is being rational. The person who rejects the argument, and rational thought, has a right to do so, but should at least be honest about it.
