Apologetics and Evangelism: A Philosophical Debate · Reformed Thinking

0:00
Have you ever, you know, stopped to think about what's really
0:02
underneath all your thoughts? Like your reasoning, even how
0:06
you decide what's true? What if the whole way you make
0:09
sense of things depends on something you maybe don't even
0:12
buy into? That's a big question to start
0:15
with. It is welcome to the deep dive.
0:17
Yeah. And today we're really getting
0:19
into something fascinating, this major historical debate.
0:24
It wasn't just like a friendly chat.
0:26
It was a serious clash asking, well, the biggest question,
0:29
right? Does God exist?
0:31
We're calling this specific deep dive Reformed thinking.
0:35
And that's right. Our focus is that well, pretty
0:37
well known debate between Doctor Greg Bonson and Doctor Gordon
0:40
Stein. Bonson arguing for Christian
0:42
theism from a presuppositional angle.
0:44
Which will definitely unpack. Oh yeah, and then Dr. Stein
0:47
presenting the atheist view more from an evidential standpoint.
0:50
This all went down at the University of California,
0:52
Irvine. David Agopian from their speech
0:55
and debate team moderated. Right.
0:58
And our goal here really is to pull out the main ideas, the
1:00
different ways these two thinkers argued.
1:02
Yeah, So you can get a better handle on how world views shape
1:05
everything, even how we think about logic itself.
1:08
Yeah, and what it really takes to argue for or, you know,
1:11
against God's existence. OK, so let's set the scene a bit
1:14
more. Who are these guys?
1:15
All right, so Doctor Greg Bonson, he was a Christian
1:18
philosopher, A theologian, had multiple master's degrees from
1:22
Westminster Theological Seminary, a pH.
1:25
D in Philosophy from USC Solid. Credentials.
1:27
Definitely wrote several scholarly books.
1:29
Apologetics, ethics, theology. He was also a pastor when this
1:34
debate happened, and the key thing for our discussion is his
1:37
method. Presuppositional.
1:39
OK, and facing him, Doctor Gordon Stein, an American
1:43
scholar, a pretty prominent figure in atheism back then, PhD
1:47
from Ohio State. He wrote quite a bit, 25 books,
1:51
one title was pretty bold. How to argue with a theist and
1:54
win? Tells you where he's coming
1:56
from. Yeah, no ambiguity there.
1:57
He was president of groups like the American Rationalist
2:00
Federation, the Free Thought Association, so a significant
2:04
voice for atheism and secular humanism at the time.
2:06
And the venue? UC Irvine, their speech and
2:10
debate team, which was nationally ranked, hosted it.
2:13
The president, David Agopian, he was the moderator.
2:17
And he laid down some pretty strict rules, didn't he?
2:19
He did very structured format, a hybrid debate format, he called
2:23
it. No applause, no camera flashes,
2:25
no audience participation at all.
2:27
Yeah, I remember reading he he even mentioned having CSO
2:30
officers and like former football players there to keep
2:33
order. Right, really emphasizing the
2:35
academic, serious nature of it. Just focus on the argument.
2:39
And the core question, plain and simple, does God exist?
2:42
So how did they kick things off? Their opening stances are really
2:45
telling. Bonson was very clear he wasn't
2:48
just defending some vague idea of God, but specifically
2:52
Christian theism as a whole system.
2:55
Right, not just bits and pieces. Exactly.
2:57
And he kind of headed off some common objections right away.
3:00
Things like, you know, hypocritical Christians or
3:03
historical atrocities done in the name of religion or even by
3:06
atheists like Jury, the French Revolution's Reign of Terror or
3:09
the Spanish Inquisition. Yeah, he acknowledged.
3:11
Those things happen. But his point was those actions
3:14
don't automatically invalidate the philosophical system itself.
3:17
Yeah, he wanted to talk about the coherence and truth of the
3:21
Christian worldview as a framework for thought.
3:24
OK, so Bonson focused on the system.
3:26
What about Stein? Stein came out saying his goal
3:29
was to look at the proofs theists offer and show why they
3:32
don't work. He was careful about defining
3:34
atheism, too. How so?
3:36
He said an atheist isn't someone who proves God doesn't exist, or
3:39
even denies God exists necessarily.
3:41
It's simpler. An atheist is someone who has
3:44
looked at the theists arguments and finds them, well,
3:47
inadequate, unproven. So the burden of proof is key
3:50
for him. Absolutely.
3:52
He used analogies. A man claiming he can fly, a dog
3:55
talking. He said, look, the person making
3:57
the extraordinary claim has to provide the proof.
4:00
If they don't, you just don't believe it.
4:02
You're without belief. It's not that you have proof
4:03
they can't fly. OK, that makes sense.
4:05
So let's get into Bonson's approach, this presuppositional
4:09
method. It's different from what many
4:11
people might expect. It really is.
4:13
His basic idea is that everyone starts with certain foundational
4:17
beliefs, core convictions about reality, knowledge, truth,
4:21
whether you realize it or not. This is a presupposition.
4:23
Exactly. And these presuppositions act
4:25
like lenses. They shape how you interpret all
4:28
the evidence that comes your way.
4:30
It's not that evidence doesn't matter, but your worldview
4:34
determined to what you even count as evidence and what it
4:36
means when you see it. So no truly neutral observer in
4:41
his view. Pretty much.
4:42
You don't just look at facts blankly.
4:44
Your underlying framework tells you how to connect the dots.
4:48
OK, so he wasn't just offering proofs for God in the usual way.
4:52
Not primarily, no. He was questioning the very
4:55
ground rules of how we evaluate evidence.
4:58
He took issue with Stein saying the God question is just another
5:02
factual question, like checking for crackers in a pantry.
5:05
The crackers in the pantry fallacy.
5:07
That's what he called it, he argued.
5:09
Look, different kinds of things need different kinds of proof.
5:11
Barometric pressure? You measure it.
5:14
Quasars. You observe them
5:15
telescoptically. Natural laws, numbers, love,
5:19
beauty. These aren't physical objects in
5:21
a pantry. Right, you need different
5:23
methods. Exactly.
5:24
So the type of evidence you look for depends on what you're
5:26
talking about. You don't measure love with a
5:28
yardstick or put gravity under a microscope.
5:31
Bonson's point was God being transcendent.
5:34
Spiritual isn't the kind of thing you'd find like crackers.
5:37
The message has to fit the subject.
5:39
And then he went further, challenging Stein's own
5:41
foundation. He did.
5:43
He pointed out what he called the pretended neutrality
5:45
fallacy. Stein had said basically that
5:48
logical reason is the only valid way to check factual claims.
5:52
OK, sounds reasonable on the surface.
5:54
But Bonson asked, how do you prove that statement itself?
5:58
If you use logic to prove that logic is the only way?
6:01
Well, that's circular reasoning, right?
6:04
Which Stein himself said was bad.
6:06
OK, I see the problem. And if Stein uses something
6:09
other than logic to prove it, then his own rule that logic is
6:13
the only way is broken. So Bonson is saying Stein's
6:16
reliance on logic as the ultimate authority is itself an
6:19
unproven starting point, a presupposition.
6:23
Precisely. It's a core belief Stein holds,
6:26
not something he empirically demonstrated before using logic.
6:29
And Bonson connected this to Stein's view of science, too.
6:32
Yes, he argued, Stein's predication to naturalism, the
6:36
idea that supernatural explanations are not allowed in
6:39
science, was another unproven assumption.
6:41
It just begs the question, Bonson said.
6:43
Meaning it assumes what it's trying to establish.
6:45
Kind of. It rules out God from the start,
6:47
before even looking at the evidence from nature or history.
6:49
It sets the rules of the game in a way that automatically
6:52
excludes atheistic interpretation, Bonson
6:55
suggested. This is just as much a worldview
6:57
commitment as atheist interpreting things through
6:59
their lens. So his whole point was everyone
7:02
has these lenses, these starting points, you can't escape them.
7:05
That was the setup to show that neutrality is an illusion and
7:09
everyone argues from a worldview.
7:11
OK, so after critiquing Stein's foundation, what was Bonson's
7:15
positive case? This transcendental argument
7:18
tag. Right.
7:19
This was the centerpiece tag, the transcendental argument for
7:22
God's existence. His goal, he said, was to prove
7:26
the existence of God from the impossibility of the contrary.
7:29
Well, that sounds ambitious. What does that mean?
7:32
Impossibility of the contrary. It means, he argued, that if you
7:35
don't presuppose God, specifically the Christian God,
7:38
you actually lose the ability to prove anything at all.
7:42
His claim was incredibly bold. Without him, God, it is
7:45
impossible to prove anything. So not just that God exists, but
7:48
that God is necessary for proof itself.
7:50
That's the core of it, he argued.
7:52
The atheist worldview ultimately self destructs because it could
7:55
cannot consistently provide the preconditions of intelligible
7:59
experience, science, logic, or morality.
8:02
OK, how did he try to show that? Let's take logic for example.
8:05
Good example. He zeroed in on the laws of
8:09
logic. Like a law of non contradiction,
8:12
something can't be both true and false in the same way at the
8:14
same time. He asked what are these laws?
8:17
OK, what are? They well, Bonson pointed out,
8:20
they seem to have certain properties.
8:22
They're universal. They apply everywhere, always.
8:24
They're invariant. They don't change.
8:27
And, crucially, they're immaterial.
8:29
They aren't physical things. You can't weigh or measure the
8:32
law of non contradiction. Right, they're abstract
8:35
concepts. Exactly.
8:36
He called this their transcendental necessity.
8:39
Now the challenge he posed to atheism was how does a purely
8:44
materialistic worldview, where everything is just, matter and
8:46
energy, account for these universal, unchanging,
8:50
immaterial laws? If they're just human
8:52
inventions. Right.
8:53
If they're just conventions, like rules of grammar, or maybe
8:56
just how our brains happen to be wired through evolution, Bondson
8:59
argued. They lose their absolute
9:00
authority. Why couldn't another society
9:03
just invent different laws of logic?
9:05
How can we even have a rational debate or do science if logic
9:08
wasn't universally binding? So he's saying atheism can't
9:11
provide a solid ground for logic.
9:13
That was his contention, he said.
9:15
The atheist worldview cannot allow for laws of logic in this
9:20
robust sense. He even famously told Stein that
9:24
when Stein used logic to argue against God, he was actually
9:27
borrowing from the Christian worldview.
9:29
Why borrowing? Because, Godson argued, these
9:33
abstract, universal, unchanging laws make perfect sense if
9:36
there's a God whose very nature is rational and consistent, who
9:39
created a universe that reflects that order, a God who stands
9:43
against contradiction. OK, I see the connection he's
9:45
drawing and did he apply this to anything else?
9:47
Yes, definitely to the uniformity of nature.
9:50
This is the assumption that the basic laws of physics and
9:53
chemistry will work the same way tomorrow as they do today.
9:55
It's fundamental for science, right?
9:57
Absolutely. You couldn't do experiments
9:59
otherwise. Bonson asked What basis does
10:01
atheism have for assuming this uniformity in the universe
10:05
that's ultimately just random matter in motion?
10:08
Why should nature be orderly and predictable?
10:11
He argued. The Christian rule view with a
10:12
faithful God upholding creation, provides A rational basis for
10:16
expecting this uniformity. So for Bonson, God isn't just
10:20
one more fact in the universe, but the necessary foundation for
10:24
understanding the universe rationally.
10:26
That's a great way to put it, The preconditions of
10:28
intelligibility. OK.
10:30
Let's switch gears now to Doctor Stein's arguments.
10:33
How did he respond and what was his overall strategy?
10:37
Stein's strategy was more, let's say, traditional and apologetic
10:41
debates. He focused on defining terms
10:43
clearly and then systematically refuting arguments for God's
10:47
existence. We mentioned his definition of
10:49
atheism, finding the proofs inadequate, and the burden of
10:52
proof point. Right.
10:54
He also offered a specific definition of God for the
10:56
debate, a supreme personal being, distinct from the world
11:00
and creator of the world. He noted this was similar to 1
11:03
used in the famous Copleston Russell debate.
11:06
So establishing common ground on what they were debating about.
11:08
Exactly. And then he made that strong
11:10
statement about science. Supernatural explanations are
11:13
not allowed in science. Why did he see that as so
11:15
crucial? He felt allowing them would be
11:18
begging the question using the thing you're trying to prove the
11:21
supernatural as part of the explanation.
11:24
He also thought it would just stop scientific inquiry.
11:27
If any weird result could just be chalked up to God did it, why
11:30
bother looking for natural causes?
11:32
A kind of methodological naturalism for science.
11:36
He saw sciences operating, by definition, almost on an
11:40
atheistic premise, seeking only natural explanations.
11:43
OK, so from that foundation he went on the offensive against
11:47
theistic arguments. He did.
11:48
He went through a list. He mentioned 11 major ones.
11:51
Let's touch on a few key ones. Like the cosmological argument,
11:54
the first 'cause idea, Yeah. Science critique was basically
11:58
if everything needs a 'cause then God must need A cause too.
12:02
That leads to an infinite regress.
12:04
Or, he said, if you claim God doesn't need A cause, well then
12:07
maybe the universe doesn't need A cause either, so the argument
12:10
fails. But as you mentioned earlier,
12:12
that might misunderstand the classic argument.
12:14
It often does. The argument usually isn't
12:16
everything needs a cause, but everything that begins to exist
12:20
needs a cause, or every contingent thing needs a cause.
12:25
The conclusion is a necessary uncaused being.
12:28
Stein's version is a bit of a simplification, or maybe even a
12:31
straw man, depending on how charitable you want to be.
12:33
OK, what about the design argument?
12:36
Things look designed, so there must be a designer.
12:38
Similar critique from Stein. If the universe needs a designer
12:42
because it's complex, then God, who must be even more complex
12:46
and wonderfully designed, would need an even greater designer.
12:50
Again, infinite regress. Right, The Who designed the
12:53
designer objection? Then there was the argument for
12:56
the Bible. Stein dismissed that pretty
12:58
quickly as circular reasoning, using the Bible to prove God
13:01
assumes the Bible is inspired by God, which assumes God exists.
13:05
OK, that's a common objection. Miracles.
13:07
He said arguing for miracles also begs the question by
13:10
assuming the supernatural is possible in the first place, he
13:13
quoted Thomas Paine. Basically, it's always more
13:15
likely someone is mistaken or lying than that the laws of
13:18
nature were violated. A skeptical stance on testimony
13:21
versus natural law. Ontological argument proving God
13:25
from the concept of perfection, Stein said.
13:28
Look, just because you can define something as perfect
13:31
doesn't mean it exists. Existence has to come first or
13:34
be demonstrated, not just defined.
13:36
The perfect island objection, basically.
13:38
Right and the moral argument. Objective morals point to God.
13:42
Stein offered naturalistic alternatives.
13:44
Morality as a survival tool. Learned behavior passed down
13:48
culturally. And he pointed to moral
13:50
diversity. Yeah.
13:51
He argued if morality came directly from God, shouldn't
13:54
everyone have the same moral code?
13:56
The fact that we don't suggest it's more likely a human or
13:58
cultural construct. He also briefly hit others life
14:02
wish, faith experience, Pascal's Wager.
14:05
Yes, quickly. Evolution explains life.
14:07
Wishing doesn't make things real.
14:09
Faith is belief without evidence.
14:10
Religious feelings aren't facts, and Pascal's Wager is a bad bet
14:13
based on fear and picking the right God.
14:15
He was clearly prepared to address that whole range of
14:18
standard theistic arguments. So Stein's approach was really
14:21
about dismantling the evidence presented by theists.
14:24
Primarily, yes, Knocking down the pillars of theistic proof as
14:27
he saw them. But how did he handle Bahnson's
14:30
challenge about the foundations, particularly logic and
14:33
scientific laws, from an atheist perspective?
14:36
This is where the debate got really focused, especially in
14:38
the cross examination. Stein did offer explanations for
14:42
laws of logic. He said they are universal but
14:45
also agreed upon by human beings.
14:48
He called them conventions, sociological laws, or laws of
14:51
thought. Conventions like traffic laws.
14:55
Sort of. But he also explicitly denied
14:57
that a law could be material. He seemed to struggle a bit
15:00
here. Later he described them as
15:02
consensuses based on observations.
15:05
He even brought up Zen Cohen's as maybe suggesting different
15:08
kinds of logic exist. So a bit inconsistent.
15:11
Are they universal or conventions or based on
15:14
observation? It seemed hard for him to pin
15:16
down a consistent naturalistic account that captured their
15:19
apparently necessary and universal character for
15:22
scientific laws. He defined them more
15:24
statistically and observation that's made over and over again.
15:27
Not absolute decrees, but descriptions of regularities.
15:30
Right. And where does that regularity
15:32
come from? He attributed it to the inherent
15:34
property of matter, like electrons, just to behave this
15:38
way. Magnets just do attract or
15:39
repel. This inherent behavior, he
15:42
argued, creates a logical, rational universe without a God.
15:46
So order arises from the properties of matter itself.
15:49
That was his claim. He concluded that lacking a God
15:51
wasn't detrimental to logic into having laws in the atheist
15:55
universe. He felt he had offered a
15:57
sufficient naturalistic explanation.
15:59
OK, so that sets up the direct clash, particularly when Bonson
16:03
got to cross examine Stein. Exactly.
16:05
Bonson really pressed him. He kept asking about Stein's
16:08
definition of atheism, his sources, and pointedly asked if
16:11
Stein felt he had actually addressed the transcendental
16:13
argument. Bonson clearly wanted to keep
16:16
the focus on that foundational challenge.
16:18
And the exchange about the laws of logic being immaterial was
16:21
key. Absolutely pivotal?
16:23
Bonson asks. Are laws of logic universal?
16:25
Stein says yes, Are they material?
16:28
Stein says no, a lot can't be material.
16:30
OK, then, Bodson asks. Can you give me an example of
16:32
something else that's universal and immaterial besides God?
16:37
Putting him on the spot. Big time.
16:39
There's a pause in the recording, apparently.
16:41
Then Stein offers laws of logic. Using the thing they're debating
16:45
about logic itself as the example.
16:47
Exactly. Bonson jumps on this How can
16:49
Stein, arguing for a purely materialistic universe,
16:53
acknowledge these powerful universal, immaterial entities
16:57
like laws of logic without contradicting his own worldview?
17:01
It seemed like a major inconsistency Bonson was
17:03
highlighting. Did Bonson push on other
17:06
immaterial things? Yeah, he asked about ghosts, the
17:09
soul. Stein actually conceded that
17:11
humans have an immaterial aspect.
17:13
Really, that seems like a big concession for his position.
17:16
It does. Stein tried to kind of brush
17:18
past it, but Bonson brought it back, pointing out the seeming
17:21
circularity of Stein possibly referencing the Bible implicitly
17:24
or explicitly for ideas about man's immaterial aspect, while
17:29
simultaneously denying the Bible's authority and God's
17:31
existence in the main debate. So Bonson was constantly trying
17:34
to show internal contradictions in Stein's framework.
17:37
That was the core of his strategy during the interaction
17:39
phases, exposing alleged inconsistent.
17:43
How did commentators view their styles afterwards?
17:46
A common take is that Stein seemed, well, maybe blindsided
17:50
is too strong, but certainly unprepared for Bonson's specific
17:54
presuppositional attack. Stein was ready for evidential
17:57
arguments, but this foundational critique of the basis for
18:01
knowledge and logic itself seemed to catch him off guard.
18:04
So he stuck to his prepared points.
18:06
Often, yes, he'd circle back to his refutations of the 11 proofs
18:11
rather than directly grappling with Bonson's transcendental
18:14
argument in depth. It felt like he was answering
18:17
the arguments he expected, not always the ones Bonson was
18:20
making. And Bonson.
18:21
He was generally praised for being very disciplined, very
18:24
clear, and really controlling the flow of the debate by
18:27
constantly bringing it back to his core argument about
18:29
presuppositions and the impossibility of the contrary.
18:32
He didn't lay everything out at once, which let him keep
18:34
pressing Stein on foundations. OK, let's step back and compare
18:38
the two approaches more broadly. What are the takeaways about
18:42
presuppositional versus evidential apologetics from this
18:45
debate? Well, Bunsen's presuppositional
18:47
approach, its strength is that it goes straight for the
18:50
foundations, the underlying worldview, it challenges those
18:53
pre dedications everyone has. It tries to unmask that
18:56
pretended neutrality. Exactly.
18:59
It highlights that everyone starts with unproven
19:01
assumptions, and its main positive argument tag focuses on
19:06
the impossibility of the contrary, arguing that only the
19:10
Christian worldview can consistently account for things
19:12
we take for granted, like logic, science, morality.
19:17
So it aims for the root, not just the branches.
19:19
Right. Instead of just swatting it
19:22
individual arguments, which Bunsen thought was like putting
19:25
out small fires while the main fuel source remains, it tries to
19:28
show the whole opposing structure is unsound.
19:30
This gives the presuppositionalist a way to
19:32
control the debate, forcing the opponent onto the defensive
19:35
about their own worldviews. Consistency.
19:37
And it seemed effective here because Stein wasn't ready for
19:40
it. It's certainly seen that way.
19:41
For Bahnson, this wasn't just a debate tactic either.
19:44
He saw it as showing the foolishness of unbelief, hoping
19:47
God would use it. OK, what about the evidential
19:49
approach Stein used? What are its strengths and where
19:53
did it seem weak in this particular encounter?
19:55
The strengths of evidentialism generally are its focus on
19:59
reason. Logic, empirical evidence,
20:02
treating God's existence like a scientific hypothesis or a
20:06
historical question. Stein did this well.
20:09
He clearly put the burden of proof on the theist.
20:12
And he was ready for those standard proofs.
20:14
Very much so. His systematic rebuttal of those
20:16
11 arguments showed preparation in that area.
20:19
But the weaknesses as highlighted by Bahnson.
20:22
Well, the crackers in the pantry problem may be oversimplifying
20:25
what kind of thing God is. The potential circularity in its
20:28
own foundation, like assuming logics authority without
20:31
grounding it. The pre dedication to naturalism
20:34
that arguably screened out possibilities unfairly from the
20:37
start. And the struggle to account for
20:39
things like logic. Yes, that seemed to be a major
20:42
sticking point. Trying to explain universal
20:45
immaterial laws as just conventions or observations or
20:50
properties of matter didn't seem fully convincing or consistent,
20:53
especially under Banson's cross examination.
20:56
He also seemed to mischaracterize some arguments,
20:58
like the Cosmological 1. And fundamentally, he didn't
21:02
seem to engage deeply with Banson's core transcendental
21:04
challenge. So wrapping this up, what should
21:07
you or listener take away from this whole exchange?
21:10
The biggest thing is seeing the debates about God aren't just
21:14
about isolated facts, they're really about entire world views
21:17
colliding. Everyone, consciously or not,
21:20
has these foundational beliefs that color how they see
21:23
everything. There's no truly neutral
21:25
viewpoint when you get down to these ultimate questions.
21:27
Right. And that leads to the question,
21:28
which worldview actually makes the most sense of reality as we
21:32
experience it? Which one provides a more
21:34
coherent, consistent explanation for things like logic, the
21:37
orderliness of nature that allows science even our sense of
21:40
morality? Does a purely naturalistic
21:43
universe account for those things as well as or better than
21:47
atheistic one? Yeah, that's the challenge
21:49
posed. And remember Bonds?
21:51
It's perspective. Wow.
21:52
This wasn't just intellectual sport.
21:53
It was about demonstrating the rationale of belief and the
21:57
potential pitfalls of unbelief, hoping it would have a real
22:00
effect on people's thinking and ultimately their relationship
22:03
with God. So maybe a final question for
22:05
you to chew on. What does it mean if the very
22:08
tools you use to think and reason your logic, your
22:12
scientific method might themselves depend on a
22:15
particular worldview to be fully justified?
22:17
If the foundation requires something you don't currently
22:20
accept, what does that imply? It's definitely something worth
22:23
pondering as you continue to think through your own
22:26
understanding of the world. We really hope this deep dive
22:28
into the Bondsenstein debate has given you some clarity, maybe
22:32
sparked some new thoughts about God, how we argue about belief,
22:35
and those deep down assumptions that guide us all.
22:37
Yeah, we definitely encourage you to keep thinking about these
22:39
things. Look at your own
22:40
presuppositions. How do they shape how you see
22:43
reality? It's a worthwhile exercise.
22:46
Absolutely. Well, thank you for joining us
22:48
for this deep dive. We look forward to our next
22:51
exploration together.
