For my first official published post on this blog, I am
going to tackle an interview sent to me by a friend regarding the Cosmological
Argument for the existence of God. The interview was given by Catholic
Answers Live, and posted on Nov 14, 2011, at the following address:
Information on Fr. Spitzer can be found on his Wikipedia
page, found here:
I will be tackling each point in the interview by marking
the time stamp from the above interview and providing counterpoints below.
6:22
Fr. Spitzer Tries to pin Negative Proof Fallacy on Hawking while admitting he
doesn't commit the fallacy. The problem is, though you cannot disprove the
supernatural with natural evidence, you can't prove the supernatural either.
You can not easily infer that God exists or does not exist in this case;
and even if one could logically infer the existence of God, you could not infer
the attributes of God, meaning that the Christian God is no more likely than
Zeus, Thor, Odin or Gorglax, the god worhipped by the lizard peoples of Xroglan
8. Given that the only source of information regarding the supernatural
is the human psyche, it is not a very convincing argument for Catholicism.
7:26
Here Fr. Spitzer gives what is known as the "God of the Gaps"
argument. This argument essentially consists of the following:
- Science
has not discovered the totality of all knowledge.
- Therefore
science has gaps.
- Whatever
gaps remain in science can only be explained by God.
This
is actually a very old argument, dating back thousands of years, used to
describe mysterious planetary motion that we now have a very good understanding
for. What exists at the center of this argument is a certain arrogance
that says, "Things we do not currently know, we can never know."
Through time, the scientific process has done a lot to shrink the gaps in
human knowledge, and as a result, the God of the Gaps also shrinks. Neil
deGrasse Tyson addresses this argument very eloquently in an essay entitled,
"The Perimeter of Ignorance", located here.
9:00
Here is an interesting double standard as presented by Fr. Spitzer. In
this case he rails on String Theory for having no observable evidence, even
though he himself admitted that there was no supernatural evidence for God,
either. So why believe in God, and not String Theory?
11:00
Oversimplifies the nature of "nothing", then overtly applies
the God of the gaps fallacy by stating that God had to cause something from
nothing (@11:20), making the statement even though previously he stated that
you could not prove (or disprove) supernatural existence with natural evidence.
The problem with the oversimplification of nothing is this:
Nothingness
is only defined by its lack of observable energy or matter. Science (as
far as I am aware) is not making the claim that the Universe came from complete
nothingness, only that all matter and energy were compacted into a nearly
infinitely small and dense package. Nothingness surrounded that package,
and when the Big Bang exploded, the outer edge of traveling energy and matter
became the boundary to our observable universe. It is helpful to think of
the Big Bang, not as a distant event in the past, but as an event that is still
occuring. As the Universe expands, it is continuously turning the
nothingness into the somethingness of our Universe, contrary to Spitzer's
claim.
12:00
Again, reiterates God of the Gaps fallacy.
13:20
A probabilistic fallacy by suggesting that the current state of our
universe had to be guided by design because of the extremely low probability
that our current low entropy universe exists. If I go to a beach with a
trillion grains of sand, and pick one at random, there is a 1 in a trillion
chance that i will pick any given grain. Therefore, the grain I do pick
up would naturally assume that I picked it on purpose because of the low
probability I would pick it by chance. The other problem here, is Fr.
Spitzer does not explain why a low entropy Universe is particularly special.
Just because we were the grain of sand on the beach that got picked, are
we safe to assume that others do not have special properties to allow for
intelligent life, or that the existence of intelligent life is a particularly
special attribute?
23:00
At this point, Fr. Spitzer makes the claim that for any theory where
universes are inflationary, there is a point in the past where these universes
had to spawn from nothing. The BVG Theorem that he cites is apparently
the new frontier of apologetics; since apologists like William Lane Craig can
no longer use the Big Bang theory as their theorem of choice due to the fact
that general relativity no longer makes sense at the quantum level.
However, the BVG Theorem never makes the claim that multiverses come from
nothing; they only claim that theories involving inflationary universes are
incapable of explaining the complete past. What this means is that,
instead of suggesting that multiverses inflated from nothing, they suggest that
there is a point in the past where inflationary theory no longer makes sense.
From the paper:
"Many inflating spacetimes are likely to violate
the weak energy condition, a key assumption of singularity theorems. Here we
offer a simple kinematical argument, requiring no energy condition, that a
cosmological model which is inflating -- or just expanding sufficiently fast --
must be incomplete in null and timelike past directions. Specifically, we
obtain a bound on the integral of the Hubble parameter over a past-directed
timelike or null geodesic. Thus inflationary models require physics other than
inflation to describe the past boundary of the inflating region of
spacetime."
In the words of Vilenkin himself:
The theorem says that if the universe is
everywhere expanding (on average), then the histories of most particles
cannot be extended to the infinite past. In other words, if we follow the
trajectory of some particle to the past, we inevitably come to a point where
the assumption of the theorem breaks down—that is, where the universe is no
longer expanding. This is true for all particles, except perhaps a set of
measure zero. In other words, there may be some (infinitely rare) particles
whose histories are infinitely long.' [...] I then asked Vilenkin, “Does your
theorem prove that the universe must have had a beginning?” He immediately
replied, No. But it proves that the expansion of the universe must have had a
beginning. You can evade the theorem by postulating that the universe was
contracting prior to some time.'

29:40 Great question from a kid
named James, who asks, "When God created the world [sic], who created
God?" Fr. Spitzer gives a rather puzzling answer; "the question
assumes that everything needs a cause, and you don't need to do that in any
kind of a proof. The only thing that needs a cause is something that has a
beginning, or something that's contingent...the reason we think our universe
needs a cause is because our universe likely has a beginning." He
goes on to state that there is all kinds of evidence that our universe had a
beginning, and therefore, requires a cause.
This is an
oversimplification of current cosmological theory. As I understand it,
the theory only uncovers the beginnings of the current universe as we know it,
but beyond the barrier in the past where relativity breaks down, we really have
no idea as to the events prior. It is important to reiterate that nowhere
in the current scientific model is it stated that the universe is generated
from nothing.
31:40: A caller Cecil essentially
makes the Argument from
Beauty. Fr. Spritzer replies with an example of mathematical
equations, likely referring to fractals or the mandelbrot set. While
these are indeed beautiful (ex, here), he fails to provide
an argument as to whether or not they are transcendentally beautiful, as
opposed to the sense of beauty being generated within the human psyche.
35:00 Fr. Spritzer again commits the
same probabilistic fallacy that I mentioned above. It should be noted that
stating that the universe is fine tuned for life is dubious at best, especially
considering that 99.9999999+% of the universe is inhospitable to human life.
It is also important to note that Fr. Spritzer is making the assumption
that human life is the only important factor to consider for the fine tuning of
the universe. While it is possible to surmise that human life is not
possible with slight variations of universal constants, it is not possible to
say that all life is not possible, and illogical to say that human existence is
the necessary goal of the universe.
In closing, I find it interesting that
the book that Fr. Spitzer was plugging is titled "
New Proofs for the Existence of
God", yet he did not present anything resembling a proof for any god at
all, much less the Christian/Catholic God. The Cosmological Argument is
hardly a new one, and in my mind, it is not a very convincing one.
