I just listened to Emery get his butt kicked by Tony in the podcast of chapter 3 (In the Beginning there was a great SURGE) and I felt I had to respond. I am an atheist and although I do think the cosmological argument is one of the better arguments the theist has in his arsenal, it ultimately does not succeed. Here's how I would have responded to this chapter.
First of all, I noticed that the entire podcast was about what caused the universe; ie. what kind of cause it could possibly be, whether an infinite number of causes is rational or not, whether the explanation of God is better than no explanation, etc. Never was the cosmological argument itself questioned. Emery implicitly conceded, whether he did it intentionally or not, the cosmological argument and essentially let the theist in through the front door which is why Tony won the debate hands down. So let's have a look then at the cosmological argument as stated in the book:
1. Everything that has a beginning has a cause
2. The universe had a beginning
3. Therefore the universe had a cause
Although the authors don't call this Kalam Cosmological Argument in the book, it looks very similar to it. I've actually never seen the cosmological argument written in exactly this way before. According to the back cover of I Don't Have Enough Faith to be an Atheist (IDHEFA) Geisler has a PhD in philosophy so maybe there's something I'm missing here, but I have a bone to pick with the wording of this argument. Premise (1) doesn't seem to be entirely correct the way it is written because I can think of some things that have a beginning in a non-temporal sense, but the fact that they have a beginning has no relation on whether they had a cause or not. For example a book has a beginning and an end. The beginning of IDHAFA is the table of contents or the forward, and then end is the Notes or Appendix 3. The fact that the book has a table of contents has no relation at all to whether it has a cause. It is not specifically stated in this formulation of the argument that the beginning is a temporal beginning as it is explicitly stated in the much more well known Kalam Cosmological Argument by Craig:
4. Everything that begins to exist has a cause
5. The universe began to exist
6. Therefore the universe had a cause
I accept (4) but I have to reject (1). He (Geisler) mentions that (1) is the equivalent to the Law of Causality, but in order for that to be the cause he must specify that the beginning is actually a beginning in time because according to the definition of causality (http://en.wikipedia.org/wiki/Causality) "Antecedence postulates that the cause must be prior to, or at least simultaneous with, the effect". You may think I'm nitpicking here but this subtle difference is critical when analyzing the second premise.
I have no problems with (2). I agree with all the evidences for the beginning of the universe that Geisler states in chapter 3, the SURGE. I grant that the universe had a beginning. However I do have problems with (5). The universe did not begin to exist because time came into existence along with everything else in the universe. There was no "before" the universe, as Tony even mentioned in the podcast. "The universe began to exist" implies that there was a time when the universe did not exist, which is not the case. Therefore (5) must be rejected.
How can I reject (5) and agree with (2)? Because just as with my example of the book above, things can conceivably have a beginning and end with that fact having no bearing on its causality. I started at the beginning of IDHAFA at the forward and read through chapters 1-15 and then finished at the appendicies, thus it has a beginning and an end. Yes it is true that the book had a cause, but I did not come to that conclusion because the book has a table of contents, but because I know that there was a time when this book did not exist and therefore it must have had a cause. Just like the book, the universe has a beginning (ie. the Big Bang) and it will have an end, although we don't know the details of that end yet. Again, just like the book, this has no bearing on whether the universe was caused or not. Only if the universe began to exist would that be the case. But the universe did not begin to exist because there was no time when the universe did not exist, therefore although we can say that the universe had a definite beginning, we cannot conclude that the universe had a cause. The universe had a beginning, but it was not a beginning in time, and that's what's important here in terms of this argument.
But what about the fact of the book itself? Regardless of whether it came to exist or not, does it not cry out for an explanation? Perhaps, but realize that is not the type of cosmological argument we are dealing with here. Chapter 3 was all about pointing to the evidence for the Big Bang and using that as evidence for the existence of God. The authors spent over 8 pages of the chapter going over the evidence of the beginning of the universe. They are using the fact that the universe had a beginning as an argument for God and that is what I am responding to here not to the contingency of objects in our universe. That's a different discussion.
So if we compare these 2 formulations of the cosmological argument, Geisler's argument (1-3) has to be rejected because (1) is false, and Craig's argument has to be rejected because (5) is false. I suspect that Geisler had intended a Kalam argument when he wrote this chapter but changed the wording for premise 2 so that he could support it with the SURGE evidence. After all, he didn't write this book for PhD philosophers he wrote it for the general public and he just wanted to get the general point across. Unfortunately the general point doesn't hold when you look at it under a microscope.
