The Craig-Pigliucci Debate:
Does God Exist?
Dr. Craig's Second Rebuttal
Second Question
The absence of evidence is not necessarily evidence of
absence. For example, we have no positive evidence of an early inflationary era in the history of the universe, and yet if you look at
many cosmologists, they believe that such an inflationary era actually existed. The absence of evidence
is not a proof that it did not exist. And over and over again in the arguments Dr. Pigliucci offered
to falsify the God hypothesis, he came back to me by saying that I haven't carried the burden of proof.
But his objections, he claims, falsify God. Now if that's true, he's got to carry his share of the
burden of proof. All I have to do is show that these objections are inconclusive.
Argument from Imperfections
So, for example, take his argument from imperfection. I responded with three points: (1)
He assumes a static theory of creation, but creationists accept microevolution. He didn't respond to
that point. (2) I said that it assumes to know what God would do, which is presumptuous. And he
says that's true, but we must have an answer. No, not at all; it's
he who thinks you have to be able to presume what God would create if He existed to carry the objection. I'm the one here to say, "I
don't know, and you don't know; therefore the objection is inconclusive." (3) I said perfection is a
relative term. A watch which doesn't function perfectly is still designed. He didn't respond to that.
I then gave the argument from evolution and pointed out that apart from God it's just too
improbable to think that natural selection and genetic mutations could have resulted in the sort of
biological complexity that we see. He didn't deny the point; he just said that I didn't quote biologists.
But notice, he didn't deny the calculations or the point. In fact, Barrow Tipler in that same book
reported that there's a consensus among evolutionary biologists today that the life of comparable
information-processing ability to homo
sapiens is so improbable that it's unlikely to evolve anywhere else in
the visible universe.{1} That's what they report as a consensus among biologists today.
Other Objections
He dropped his regression argument, dropped his "Naturalism works" argument, dropped his
Problem of Evil argument, dropped his Noah's Ark argument. So I hope that you've not seen any
persuasive reasons tonight to think that the God hypothesis is false. Dr. Pigliucci has simply failed
to falsify that hypothesis.
First Question
Now what about my reasons for believing in the existence of God?
First Argument
(1) The origin of the universe. Here he admits the premises
that Whatever begins to exist has a cause, and that
The universe began to exist. "But why," he says, "think that the cause is God?"
I gave the arguments in my first speech. I showed that it deductively follows from a cause of
space and time that the cause must be timeless and spaceless. Therefore it cannot be anything physical
and material that transcends time and space. It must be changeless. And I argued that it must be
personal because otherwise you cannot explain how a temporal effect can originate from an
impersonal, timeless cause. And he didn't refute any of those arguments. So I think in the formulation of
the argument that I gave I answered all of his objections.
Second Argument
(2) What about the complex order in the
universe? I explained the theory of probability. I did
show why his example of the people in the room is a flawed analogy. "But," he says, "Look, there's
no basis for these calculations. We don't know that these things are really improbable." What
he's really suggesting to you here is that somehow a life-permitting universe is necessary, that if we
knew of some Theory of Everything, we would see that life necessarily exists. And that is an
enormously implausible hypothesis. Paul Davies, the astrophysicist, says,
There is absolutely no evidence in favor of it. . . . Even if the laws of physics
were unique, it doesn't follow that the physical universe itself is unique. . . . the laws
of physics must be augmented by cosmic initial conditions. . . . There is nothing
in present ideas about 'laws of initial conditions' remotely to suggest that their
consistency with the laws of physics would imply uniqueness. Far from it. . . .
. . . it seems, then, that the physical universe does not have to be the way it is:
it could have been otherwise.{2}
And, in fact, as I said, when you alter those constants, those conditions, those laws, you find out
that we are balancing on a knife's edge. The origin of the universe is like the Empire State
Building's popping into existence out of nothing. That's what the atheistic hypothesis is like, if they believe
this really just happened by chance. And I find the design hypothesis far more plausible.
Third Argument
(3) What about objective morality? Here Dr. Pigliucci is clearly in a deep existential dilemma:
he affirms that morality is not objective--it is the invention of human beings--, but he cannot
bring himself to say that therefore anything goes. He wants to cling to moral values. But, you see, for
an atheist these values are floating in the air: they have no objective basis. On atheism moral
values are just social conventions. You could have chosen to go on the red and stop on the green.
They're just human inventions, the byproducts of socio-biological evolution. But that means that a
society like Nazi Germany or South Africa, where apartheid was practiced, or what happened in
Cambodia in the killing fields, that those aren't morally wrong, that is, they are morally indifferent. And I,
at least, cannot bring myself to believe that. It seems to me far more plausible that there is
objective right and wrong; for example, torturing babies for fun is wrong. And if you agree with me
tonight that that is objectively morally wrong, then you would agree with me that therefore God exists.
For he admits that if we have no God, these things are not objectively wrong, but they're human
conventions.
Fourth Argument
(4) What about the life, death, and resurrection of
Jesus? Here he asks, "Why think that Jesus
was special?" Very simply: because of the evidence for his resurrection! No other founder of
any religion in history has had such a thing claimed of him. "But," he says, "Isn't it arbitrary to
believe in a miracle in this case if you don't believe in miracles in many other cases?" Not at all!
You should believe in a miracle, I think, when (1) No naturalistic explanation of the facts is available
that plausibly explains the facts, and (2) There is a supernatural explanation suggested in the
religio-historical context in which the event occurred. The resurrection of Jesus is significant not
just because anyone or someone rose from the dead, but because Jesus of Nazareth, who claimed to
be the absolute revelation from God, rose from the dead. And what is significant is that Dr.
Pigliucci hasn't been able to deny any of those three facts that the majority of New Testament critics hold
to today: the empty tomb, the resurrection appearances, and the origin of the disciples' faith. Those
are the historical facts. Now you can pursue agnosticism if you want. You can just say "Well, I
don't know the explanation." But I certainly think a Christian is within his rights to say, "You know,
it looks to me like those men were telling the truth," that the best explanation is that Jesus
did rise from the dead. So you can remain agnostic if you want to, but it seems to me that as a historian
I'm certainly within my rational rights to say the best explanation is that Jesus rose from the dead.
Fifth Reason
(5) Finally, the immediate experience of
God has not even been discussed tonight in this debate.
But I think one can know immediately that God exists as well.
