Thanks to everyone, especially Knight and Squishes, for allowing this debate to occur. In my opening statement, I will defend three arguments that I maintain give us good reasons to believe that God exists.
The Argument from Change
1. Changing things exist. (Premise)
2. Changing things exhibit potentiality and actuality. (Premise)
3. No potentiality can actualize itself. (Premise)
4. Either some pure actuality exists, or else there is an infinite regress of potentialities being actualized. (Implied by 1 - 3)
5. There cannot be an infinite regress of potentialities being actualized. (Premise)
6. Therefore, some pure actuality exists. (From 4 and 5)
We know that changing things exist and that these changing things exhibit potentiality (what a thing could be) and actuality (what a thing is). For example, an acorn is merely an acorn in actuality, but in potentiality, it is something else, e.g. an oak tree. Yet, the acorn cannot actualize its own potentiality to become an oak tree. It requires water, sunlight and soil. If at any point these sustaining causes are removed, then the acorn will cease to become an oak tree.
The key premise, then, appears to be (5). Why can there not be an infinite regress of such sustaining causes of change? The beauty of this argument is that it is entirely consistent with an infinitely-old universe. It's just that even an infinitely-old universe is composed of finite intervals. Now, at each finite interval, the regress of sustaining causes of change begins anew. Since it is impossible to form an actual infinite by successive addition whenever one begins counting, it follows that at any finite interval, the regress of potentialities being actualized must be finite.
From (4) and (5), it follows that pure actuality exists. There are many divine attributes that one may infer about pure actuality. For one, it must be immutable, since only things that exhibit potentiality can change. Secondly, pure actuality must be eternal, indestructible and omnipresent, since there is no time or place at which pure actuality can not-exist. Next, pure actuality must be one. For, if there were more than one pure actuality, then there would be distinctions between them. Yet, to be distinct from actuality is to be non-actuality, which means the latter is non-existent anyway. Other existing entities share in the actuality of pure actuality, but are distinct insofar as they have varying levels of potentiality. Finally, pure actuality must be very powerful, if not omnipotent, in order to causally sustain the actualizations of all potentialities.
Therefore, we have an argument for a purely actual, immutable, eternal, indestructible, omnipresent, unique, and very powerful sustaining cause of all change. If this isn't God, it's certainly very much like-God.
The Modal Third Way
1. Something presently exists. (Premise)
2. Something cannot come from nothing. (Premise)
3. Either everything that exists is contingent, or else there exists at least one necessary entity N.
(Definition)
4. Necessarily, there was never a past time at which nothing existed. (From 1 and 2)
5. Possibly, there was a past time at which nothing contingent existed. (Premise)
6. Therefore, a necessary entity N exists. (From 4 and 5)
By reductio ad absurdum:
7. N does not exist. (Assumption)
8. Possibly, there was a past time at which nothing existed. (From 3 and 5)
9. (8) contradicts (4).
10. Therefore, (7) is false.
I'll simply allow Squishes to make his objections, if he has any, to this portion of the argument, and then I'll respond to those objections.
In addition, a reasonable case can be made that N is a personal agent.
11. N is either personal or impersonal. (Definition)
12. If N is impersonal, then it is a mechanical cause. (Premise)
13. If N is a mechanical cause, then it cannot cause any contingent effects. (Premise)
14. N causes contingent effects. (Premise)
15. Therefore, N must be personal. (From 11 – 14)
The key premise in this portion of the argument is (13). In support of this claim, all of the necessary conditions for producing an effect are already present in a mechanical cause. This means that if N is mechanical, then it will only produce necessary effects, which means everything that exists is necessary! Since this is manifestly false, it follows that N is a personal agent, as opposed to a mechanical cause.
The Argument from Desire
I feel this argument “hits home” to a lot of people, because it is such a personal argument. It goes like this:
1. Every innate desire corresponds with something that can satisfy it. (Premise)
2. Perfect and eternal happiness is an innate desire. (Premise)
3. Therefore, the innate desire for perfect and eternal happiness corresponds to something that can satisfy it. (From 1 and 2)
In support of (1), let's think about this inductively. If there is hunger, there is food. If there is curiosity, there is knowledge. If there is sexual desire, there sex. Examples abound, but I'll leave it at that for now. Now, someone may object: “children want to fly like Superman, but there's no Superman.” This is true, and it helps us clarify that we're not talking about any desires whatsoever, but innate desires – those desires found universally among human cultures, and that one possesses simply by virtue of being human. Wanting to fly like Superman is a socially conditioned desire, and so is impertinent to premise (1).
In support of premise (2), just ask yourselves: do you not have an innate desire to have perfect and eternal happiness, presumably with the Supreme Good, e.g. God? Only you can answer that question for yourselves. Yet, as C.S. Lewis aptly notes, “If I find in myself desires which nothing in this world can satisfy, the only logical explanation is that I was made for another world.” Since nothing in this world can give us perfect and eternal happiness, what we have is a persuasive argument for the existence of heaven and a God who cares about his creatures.
