Geisler’s Five Ways – Part 5: The Gap Between Phase 1 and Phase 2
Premise (10a) has some initial plausibility, so I can understand why Geisler does not provide an argument in support of that premise. Premise (11a), however, is clearly a controversial and questionable claim, so he needs to provide reasosns or arguments to support (11a). But NONE of Geisler’s five initial arguments proves that (11a) is true. However, premise (11a) presupposes the following two claims:
17. Anything that has a beginning must have been caused to begin to exist by something else.
1. The universe was caused to begin to exist (in the distant past) by something else.
17a. Anything that has a beginning must have been caused to begin to exist by exactly one other thing or being.
However, we can be charitable and assume that what Geisler had in mind was (17b), which is not subject to the counterexample that I just gave. If we interpret premise (17) to mean what is stated in (17b), then we need to also revise the conclusion, so that it follows logically from the combination of (16) and (17b):
17b. Anything that has a beginning must have been caused to begin to exist by at least one other thing or being.
THEREFORE:
1a. The universe was caused to begin to exist (in the distant past) by at least one thing or being other than the universe.
Or, possibly, neither of these beings would be accurately described by the term “the creator of the universe”, because they might both be considered “partially responsible” for the origin of our universe, in which case it seems misleading to call either being “the creator”. In any case, the cause of the beginning of the universe need not be “the creator” of the universe, so we cannot legitimately infer (13) from (1b).
ARGUMENT #2 OF PHASE 1
18. Finite, changing things exist.
19. Every finite, changing thing must be caused by something else.
20. There cannot be an infinite regress of these causes.
THEREFORE:
2. There is a first uncaused cause of every finite, changing thing that exists.
Here is my (partially) clarified version of this argument:
ARGUMENT #2 OF PHASE 1 – Rev. A
18a. Finite, changing things exist (right now).
19a. The current existence of every finite, changing thing that exists (right now) must be caused by something else that exists (right now).
20a. There cannot be an infinite regress of these causes (of current existence).
THEREFORE:
2a. There is a first uncaused cause that exists (right now) of the current existence of every finite, changing thing that exists (right now).
I have previously stated that the conclusion of this second argument in Phase 1 of Geisler’s case is ambiguous and has two different meanings. But in fact, it has at least four different meanings, because there are two different ambiguities in the conclusion (2a).
Here are the four different interpretations of the conclusion (2a):
2b. There is exactly one first uncaused cause that exists (right now) for the current existence of each finite, changing thing that exists (right now).
2c. There is exactly one first uncaused cause that exists (right now) for the current existence of all finite, changing things that exist (right now).
2d. There is at least one first uncaused cause that exists (right now) for the current existence of each finite, changing thing that exists (right now).
2e. There is at least one first uncaused cause that exists (right now) for the current existence of all finite, changing things that exist (right now).
The interpretations that speak of “exactly one” uncaused cause, should be rejected, because the argument cannot plausibly support such strong conclusions. For premise (19a) to be plausible, it must leave open the possibility that two or more things could work together to cause the current existence of a finite, changing thing. If one were to interpret (19a) as implying that there can only be exactly one being that is the uncaused cause of a particular finite, changing being that exists (right now), then (19a) should be rejected as an implausible claim, and thus this second argument should be rejected as well.
The Argument #2 of Phase 1 only has a hope of being acceptable if we interpret (19a) as leaving open the possibility that two or more things or beings could work together to cause the current existence of a finite, changing thing. Therefore, since the conclusions (2b) and (2c) do NOT logically follow from this argument, given that interpretation of (19a), we should reject interpretations (2b) and (2c).
That leaves us with interpretations (2d) and (2e). Interpretation (2e) should be rejected for the same sort of reason that we rejected interpretations (2b) and (2c), namely, that this would require an understanding of the meaning of (19a) that would make that premise implausible:
19b. The current existence of all finite, changing things that exist (right now) must be caused by at least one other thing or being that exists (right now).
This premise asserts that ALL of the trillions of trillions of bits of finite, changing matter that make up the universe (right now) are being caused to continue to exist by at least one thing or being. But it is clearly conceivable and logically possible that SOME of the trillions of bits of finite, changing matter that make up the universe (right now) are being caused to continue to exist by one thing, let’s call it “Thing 1” and that OTHER bits of finite, changing matter that make up the universe (right now) are being caused to continue to exist by some different thing, let’s call it “Thing 2”. Geisler has given us no reason whatsoever to reject this scenario as logically impossible, and there is no obvious reason to think it is logically impossible, so we should reject (19b) as a dubious and probably false claim, and thus reject Argument #2 of Phase 1, if premise (19) is interpreted as meaning what is stated in (19b). Thus, Argument #2 of Phase 1 cannot be used to provide solid support for conclusion (2e).
That leaves us with just one possible interpretation of the conclusion: (2d). Here is my best and final clarification of this argument:
ARGUMENT #2 OF PHASE 1 – Rev. B
18a. Finite, changing things exist (right now).
19c. The current existence of each finite, changing thing that exists (right now) must be caused by at least one other thing or being that exists (right now).
20a. There cannot be an infinite regress of these causes (of current existence).
THEREFORE:
2d. There is at least one first uncaused cause that exists (right now) for the current existence of each finite, changing thing that exists (right now).
One could still object to (19c) as being in need of a supporting reason or argument, but it is at least a bit more plausible than the other interpretations of premise (19) that we have considered. Given this interpretation of premise (19), the conclusion that is logically entailed by Argument #2 of Phase 1 leaves open the possibility that there are MANY (perhaps even trillions) of first uncaused causes of the current existence of the trillions of trillions of bits of finite, changing matter that make up the universe (right now). Becuase conclusion (2d) FAILS to rule out this possibility, it also FAILS to provide proof of claim (14):
14. There is a being that sustains the existence of the whole universe by itself (right now).
In conclusion, ARGUMENT #1 of Phase 1 FAILS to prove (13), and ARGUMENT #2 of Phase 1 FAILS to prove (14), so neither of these arguments help to prove premise (11a) of ARGUMENT #1 of Phase 2. Therefore, there is a serious logical GAP between Geisler’s arguments in Phase 1, and a key controversial premise of a key argument in Phase 2 of Geisler’s case for the existence of God.
Geisler believes that the first two arguments of Phase 1 support this key premise of the first argument of Phase 2, but he is wrong. Once we clarify the meanings of the premises and conclusions of these various arguments, it becomes obvious that Geisler’s case for the existence of God is logically invalid. (2d) does NOT imply (14), and (1a) does NOT imply (13). Geisler’s case for God thus rests on a questionable premise for which he has FAILED to provide a good reason or sound argument, namely premise (11a) in ARGUMENT #1 of Phase 2.
NOTE:
Premise (15) is a placeholder for one or more claims that when taken together show that a being that created the whole universe by itself (in the distant past) and a being that sustains the current existence of the whole universe by itself (right now) must be the same being. Geisler does not give us any reason to believe these beings are the same being.
Later on, he does argue that there can be only ONE being of infinite power and infinite knowledge, but that argument presupposes the truth of (11a) and (12a) and thus is of no help in proving the truth of (11a) at this earlier stage of his case.
