Episode 7
Is Naturalism self-defeating?
Is naturalism (the worldview that that there is no God, and that the physical universe is all that exists) actually a self-defeating idea? That is, is it making a truth claim which undermines the ability to make truth claims?
Let's discuss.
Transcript
We're back in another episode
of Philosophy in Faith, and last
2
:episode we were talking about the
four great worldviews and how they
3
:would view the questions of knowledge
in the category epistemology.
4
:And Daniel, brought up something saying
that it's possible that an objection
5
:can be made against materialism and
naturalism that is self defeating
6
:yeah, I think a good argument
could be made that way.
7
:Wow.
8
:So we're going to explore that and dive
quite a bit more deeply into that today.
9
:But as we get started, I just
want to ask you, okay, so , why
10
:are we having this discussion?
11
:What's the goal of today's episode?
12
:It's good to remind ourselves of the goal
of what we're trying to do in the podcast.
13
:We are not trying to add
to the noise and argument.
14
:We're not trying to prove
other people are wrong.
15
:our goal.
16
:is rather to make the case that
theism is at least as intellectually
17
:satisfying and coherent as any other
worldview, including naturalism.
18
:And therefore, a person is
intellectually justified in
19
:choosing that if they desire to.
20
:We're just trying to free up a person
to make that choice without feeling like
21
:they're leaving their brains at the door.
22
:Yeah, too often you hear that faith
is blind or that kind of thing.
23
:Yeah, it drives me crazy.
24
:Yeah we're going to do this
one today, asking the question,
25
:is naturalism self defeating?
26
:And then we'll have two more
episodes on the four worldviews
27
:dealing with eschatology or
history, where is history headed?
28
:And then also aesthetics,
what is beautiful, in light
29
:of those four worldviews.
30
:So two more on the worldviews.
31
:And then I think.
32
:We'll have one or two dealing with the
idea of certainty and faith and doubt.
33
:Some people think that you have
to have certainty to have faith,
34
:and I think that's very mistaken.
35
:So we'll talk about that.
36
:So in this episode you're
talking about whether or not
37
:naturalism is self defeating.
38
:Will you talk about what it means?
39
:What is self defeating?
40
:What does that mean?
41
:Yeah, very similar to, just saying
that it's self contradictory.
42
:But in terms of analyzing arguments, self
defeating is a little bit more precise.
43
:. What it means is that you are making
a claim which by its nature undermines
44
:the foundation for making that claim.
45
:Let me give you an example.
46
:I was teaching Intro to Philosophy class
and we came to the part about truth.
47
:And we were just kind of
beginning the discussion and one
48
:student volunteers says, well,
I don't believe there is truth.
49
:I don't believe you can know the truth.
50
:There is no absolute truth.
51
:And I said, Oh, so you believe
there is no truth that you can know?
52
:Yes.
53
:Okay, Bill.
54
:I think that was new.
55
:Do you mean that as a true statement?
56
:And I was amazed because you could
see the light bulb going off in
57
:his head and his eyes kind of got
bigger and he stepped back and
58
:thought, I never thought about that.
59
:And I was surprised.
60
:Yeah.
61
:Because that, objection to that
claim that there is no absolute
62
:truth undermines the concept of
truth goes at least back to Socrates.
63
:So wow.
64
:He used that against the skeptics.
65
:So, I thought it was going to
be pretty obvious that that
66
:was a self defeating statement.
67
:To say that there is no truth is making
a truth claim, but you've just undermined
68
:the ability to make truth claims.
69
:Wow.
70
:So, that's a self defeating statement.
71
:So, what we're arguing here about
naturalism is that to make the
72
:statement that naturalism is true is
a self defeating statement because it
73
:undermines your ability to make that
true statement and to know it's true.
74
:Will you walk us through it?
75
:Yeah, I'd be glad to.
76
:So, naturalism is basically the worldview
that says there is no God or gods.
77
:This material world is all that there
is, or this natural world And however
78
:you want to define that, you can
call it the cosmos, you can call
79
:it the universe, you can, this is a
more generic term, world or reality.
80
:however you want to define that,
what you're doing is you're excluding
81
:the supernatural element to it.
82
:Okay.
83
:That's at the heart of naturalism.
84
:So, Naturalism is making the claim,
the natural world is the only reality.
85
:So, who are, who are some of
the naturalistic thinkers?
86
:Well, There's all kinds of them.
87
:so Darwin would be one of them?
88
:Darwin would be a yes and no.
89
:Okay.
90
:So he actually claimed to have
a belief in God who organized
91
:and supervised evolution.
92
:It's unclear to me and maybe some other
people whether he meant that or if he was
93
:just trying to stave off the trouble of
being an atheist in late:
94
:Okay.
95
:Um, but certainly most of the people
we would call Evolutionary biologists
96
:or the new atheists, Richard Dawkins,
Christopher Hitchens, Steven Pinker, those
97
:would, embrace the label of naturalism.
98
:What's interesting here, though,
is that naturalism is almost
99
:assumed in some academic fields.
100
:they're going to operate on
naturalistic assumptions, even
101
:if no one says, I'm a naturalist.
102
:They're going to, by principle, exclude
anything but naturalistic explanations
103
:for whatever data they're dealing with.
104
:, like which academic areas or fields?
105
:biology, anthropology, but also I
think you would say the chemistry
106
:or physics perhaps medicine.
107
:So if you're asking the question.
108
:You're looking for naturalistic answers.
109
:Now, methodologically, In my opinion,
that is exactly what you should do.
110
:But there's also a drip then from,
a methodological naturalism to a
111
:philosophical naturalism where more
and more people just kind of assume
112
:then that there is no God, but
the natural world is all there is.
113
:So you're saying that that's how it should
be methodologically because you don't want
114
:to bank on the supernatural intervening?
115
:Yes.
116
:And you can't measure it.
117
:Yeah.
118
:Okay.
119
:So, yeah, when you're doing
science, you operate on.
120
:principles of cause and effect as
established by the scientific method,
121
:but there's a drift from that to the
philosophical position of naturalism
122
:that I think goes unnoticed.
123
:Gotcha.
124
:So anyway, that is naturalism.
125
:So, naturalism making the claim the
natural world is all that there is.
126
:The argument is that naturalism
is self defeating because it
127
:undermines the ability to make
truth claims, including the claim.
128
:Naturalism is true.
129
:Okay, go on and and unpack
that a little bit for us.
130
:Alright, so if we're gonna make this
into syllogism, it would, it would
131
:look like this for the statement.
132
:Naturalism is true.
133
:To be accepted as true one has
to be able to know the tree.
134
:Second premise, if naturalism is
true, one cannot know the truth.
135
:And then, conclusion, therefore,
naturalism cannot be known as true.
136
:That would be the basic argument there.
137
:Can you say that one more time?
138
:The basic form of the argument
in a syllogism form, so you got
139
:premise, premise, conclusion,
would look something like this.
140
:For naturalism to be known as true, we
must be able to make valid judgments about
141
:the truth, about metaphysical questions.
142
:And then the premise two is.
143
:Premise two is if
naturalism is true, however.
144
:It undermines our ability to make valid
truth claims about metaphysical ideas,
145
:including naturalism, because naturalism
is certainly a metaphysical claim.
146
:you know, you're, you're making as big of
a claim as you can about human knowledge.
147
:And the third, then, naturalism is self
defeating and cannot be known as true.
148
:So let's dive into this here,
149
:you know who is the surprising
originator of this argument?
150
:Um, you'll be surprised.
151
:I will be surprised?
152
:You will be surprised.
153
:Jesus.
154
:No, no.
155
:Standard answer, but not in this space.
156
:It may have arisen before, but this
particular argument, it takes its potency.
157
:Plato.
158
:No.
159
:It takes its potency from,
the theory of evolution.
160
:And the first one who raised the objection
that if naturalism is true, then we cannot
161
:know the truth was Charles Darwin himself.
162
:Really?
163
:Okay.
164
:Yeah.
165
:Let me, quote him here.
166
:This is from a letter
rd,:
167
:Quoted in the Autobiography of
Charles Darwin in Selective Letters.
168
:He once said, The horrid doubt always
arises whether the convictions of
169
:man's mind, which has developed from
the mind of lower animals, Are of
170
:any value or at all trustworthy?
171
:Would anyone trust the conviction
of a monkey's mind if there were
172
:any convictions in such a mind?
173
:Now where I don't know that he followed
through on that is this idea that
174
:if that's true and all knowledge
is therefore suspect, that would
175
:include his own theory of evolution.
176
:Hmm.
177
:So.
178
:This is recognizing that on the
naturalistic premises, you have one
179
:mechanism for humans developing the
way that we are, and therefore thinking
180
:the things that we think right now.
181
:If we are a theist, we have two options.
182
:We can believe in spontaneous
creation, that God created humanity
183
:in pretty much its present form
in the relatively recent past.
184
:But we can also believe that God oversaw
the development of an evolutionary
185
:process through many, many millions of
years to create mankind as he is now.
186
:Philosophically, a theist can
believe either one of those is true.
187
:But in either one of those, we can
say, yeah, we can know truth because it
188
:was given to us by God, not, we can't
know truth because the process was
189
:just for the purpose of reproduction,
not for the purpose of knowing truth.
190
:Unless truth gave us some
sort of competitive advantage.
191
:Yeah, you're getting
ahead of me a little bit.
192
:Okay, okay.
193
:No, that's fine.
194
:On either of these viewpoints, whether
it took six days or it took, 60 million
195
:years, what's important philosophically
for this point, especially in the
196
:area of epistemology, is this.
197
:It was guided by a rational being for
rational purpose, and that includes making
198
:mankind in his own image Including a
rational ability that works like his does.
199
:So, that is consistent with that premises.
200
:Whichever mechanism you choose.
201
:But if you reject that.
202
:If you believe that the natural world
is all that there is or ever has been.
203
:That there is nothing outside the universe
that caused it to come into being.
204
:Or that created mankind
in any shape or form.
205
:Or guided humanity's evolution
towards a certain place.
206
:It all happened by
natural processes alone.
207
:well, that's a horse of a different color
because you think through this now, if
208
:it's true, the natural selection alone,
and we should probably define this.
209
:This is just the idea that certain
traits are naturally selected to
210
:increase in a proportion in the
next generation, only because it
211
:gave them evolutionary, increased
evolutionary fitness, usually defined
212
:as they're able to get more resources.
213
:So natural selection means it's
naturally selected on that basis alone.
214
:That's the only reason that any species
is the way it is, including us, every
215
:species is formed by that alone.
216
:Including humanity, including homo
sapiens, and that includes every organ
217
:in your body, including your brain.
218
:Now, if that's true then
it's also necessarily true.
219
:That our brains are formed
by natural selection alone.
220
:Unguided natural selection.
221
:That's where the problem comes in.
222
:Because then you realize, that your
brain and therefore your thoughts,
223
:which arise out of your brain,
are formed not to find truth,
224
:for evolutionary fitness, to be
useful for reproductive fitness in
225
:different kinds of environments.
226
:That's not the same as, being able to say
that your mind is formed to find truth.
227
:So when you think through that, all
of a sudden then you have a problem.
228
:Saying that the human mind is able
to form true statements, especially
229
:about anything beyond immediate sense
experience, including the statement,
230
:the natural world is all that there is.
231
:So that's the argument in a nutshell.
232
:So how do you know that
evolutionary fitness and finding
233
:truth are mutually exclusive?
234
:I mean, Can they both be true?
235
:Yeah, so the question is, how do you
know that they are mutually exclusive?
236
:The answer is you don't know that, but
you don't know the converse either.
237
:On naturalist premises, you
cannot know evolutionary fitness
238
:and truth are the same thing.
239
:Or the mind development of one will
also be able to find the other.
240
:So the argument you're making is one that
naturals will obviously tend to make.
241
:Mm hmm.
242
:But the assumption and the
premise of that argument is this.
243
:If useful, then true.
244
:If it's useful for producing evolutionary
fitness, if it's useful for propagating
245
:more genes of that, of the species who
think that particular way, Then it's true.
246
:And when you think about it
as okay, that's a premise, but
247
:that's a premise that has not
been established or proven at all.
248
:It's an assumption made
to say of a theory.
249
:Hmm.
250
:It's not been proven.
251
:In fact, one can easily
think of counterexamples.
252
:Many ideas that may make a person
more successful at passing on
253
:genes, are maybe quite false or
at least not proven to be true.
254
:The denial of a personal God who
places restrictions on human sexual
255
:activity is just one of those.
256
:So that certainly would not be chosen
naturally because if anything, the
257
:opposite would be chosen naturally.
258
:Oh, I see what you're saying.
259
:So you're saying that if we're just the
byproduct of natural selection, that
260
:it's unlikely that a worldview with
a God that places sexual restrictions
261
:on people, it's, it's unlikely
that that would ever even emerge.
262
:Probably but that's not the
main point of my argument.
263
:The main point again is naturalism
has to make the unproven assumption
264
:that what is useful is what is true.
265
:Okay.
266
:And because it's not proven because
it's not even really readily apparent.
267
:I think you have to conclude
that the second premise is true.
268
:The naturalism undermines a
notion of regarding our brains
269
:as being able to find abstract.
270
:But can't you just say that
it doesn't, matter that we
271
:have to find absolute truth?
272
:I mean, does that matter?
273
:Well, it matters if you're trying to
develop a worldview that's coherent, that
274
:the parts don't contradict each other.
275
:Okay.
276
:I see.
277
:So if I'm arguing for a worldview,
but the premise of that worldview
278
:undermines the ability to argue for
it, that's a very deep intellectual
279
:problem with that worldview.
280
:Okay.
281
:Which is what we're talking about here.
282
:Right.
283
:I'm just learning all this for the first
time and trying to wrap my mind around it.
284
:So obviously we are not saying
that most naturalists do not
285
:believe in absolute truth.
286
:I would not begin to know how to
quantify how many of you are that.
287
:We're just saying that on the premises
of naturalism, it becomes difficult to
288
:make truth claims about naturalism.
289
:I see.
290
:I see.
291
:So not saying naturalists
aren't reasonable or logical
292
:or anything like that.
293
:Just that if you're, if you're looking
from a logical perspective, this
294
:is an objection to pay attention to.
295
:Yeah.
296
:Because if true, it's, it's a fatal.
297
:Gotcha.
298
:you can't hold a worldview that has.
299
:a self contradiction at its very heart.
300
:Yeah, unless you're okay with,
not having internal coherence.
301
:Right, but to me, I don't know how you
could be intellectually okay with that.,
302
:But I'm just curious because I feel
like at the heart of Christianity is the
303
:Trinitarian God and also the two natures
of Jesus, which are at least paradoxical,
304
:not necessarily contradictory, I guess.
305
:Yeah, I think there's a paradox that could
be worked out there, but that's not the
306
:same as having a fundamental contradiction
in the ability to make the claim
307
:about the heart of the belief system.
308
:The only analogy would be that
someone could argue that to make
309
:the statement that there is a God
undermine the ability to make that
310
:statement as a true statement.
311
:So it's not the same thing.
312
:Oh, no, no.
313
:Just an interesting point there.
314
:Yeah.
315
:There's a difference between a paradox
and an inherent contradiction at the very
316
:basis of a, of a world peace metaphysics.
317
:So anyway, let me read you a
quote here by Steven Pinker.
318
:Uh, do you know Steven Pinker?
319
:Who's that?
320
:he's an evolutionary biologist and he
was at Harvard for most of his career.
321
:I don't know if he's still there or not.
322
:Anyway.
323
:He was very influential, very smart
man, and he wrote a very large
324
:book called How the Mind Works.
325
:And he's writing this from an
evolutionary biologist's perspective
326
:and as a committed atheist.
327
:Okay.
328
:So he's a naturalist.
329
:and he gets to the chapter, after
explaining so many things about how he
330
:thinks the mind developed this way, uh,
according to the laws of natural selection
331
:alone, where he begins talking about
some of the questions we talked about.
332
:Free will.
333
:Meaning, morality, sentience, and
basically on all these, he gives
334
:some half hearted explanations
of how they might've developed,
335
:but even he sees that he doesn't
really have an answer for these.
336
:So at the end of it, he comes and he
says on page 516, we are organisms,
337
:not angels, and our minds are
organs, not pipelines to the truth.
338
:Our minds evolved by natural
selection to solve problems.
339
:There were life and death matters
to our ancestors, not to commune
340
:with correctness or to answer any
question we are capable of asking it.
341
:Let me read that again, quote, We are
organisms, not angels, and our minds
342
:are organs, not pipelines to the truth.
343
:Our minds evolved by natural
selection to solve problems.
344
:There were life and death
matters to our ancestors.
345
:Not to commune with correctness,
or to answer any question
346
:we are capable of making.
347
:But, but he means that
as a true statement.
348
:Yeah.
349
:It's just like, it's
just like your student.
350
:I mean, he's, he's, right?
351
:Isn't he saying the same thing?
352
:He is.
353
:No, I think he would qualify
that, that on other questions
354
:he was able to give a point.
355
:A true answer, but his
summary is, is interesting.
356
:He's like, we're we aren't designed
well, I don't think he'd use that
357
:word, but we are, we are here in
order to make truth statements.
358
:Exactly.
359
:And about the most important issues,
especially, he says, we have no
360
:reason to believe that we can
commune with correctness or answer
361
:any question we're able to ask.
362
:Wow.
363
:We are, my eyes are not
pipelined to the truth.
364
:So basically his words are qualified,
but the attitude is dismissive of the
365
:human mind's ability to find truth,
especially about anything of importance,
366
:like we're just talking about, especially
about something like the statement
367
:that nature is all that there is.
368
:Wow.
369
:he's a heavy hitter.
370
:This isn't an offhand remark he just made
in a question and answer session, right?
371
:This is the published writing
of a leading Darwinian atheist.
372
:And he just came to recognize it's
hard to escape the logic of the
373
:statement that if natural selection
is true, we have a truth problem.
374
:Wow.
375
:And, well, I don't know if it's
at the end, it's at least 500
376
:pages into his, his big work.
377
:Or just to the way in.
378
:Yeah.
379
:Wow.
380
:Yeah.
381
:let me read you one more quote.
382
:This is by Ann Wilson,
who was a brilliant man.
383
:He was a critic of theism and an
atheist for most of his years.
384
:Is he still alive?
385
:I don't know.
386
:In April 2009, in an article
in Mail Online, he wrote this.
387
:Quote, Our bishops and theologians,
frightened as they have been by
388
:the pouting of secularist guns,
need the kind of bravery like Sir
389
:Thomas More's more than ever now.
390
:Sadly, they have all but
accepted that only stupid people
391
:actually believe in Christianity.
392
:And that the few intelligent people left
in the churches are there only for the
393
:music, or believe it all in some symbolic
or contorted way, which when examined
394
:turns out to not be belief after all.
395
:As a matter of fact, he says, I
am sure the opposite is the case.
396
:And that materialistic atheism
is not merely an arid creed
397
:but totally irrational.
398
:Materialistic atheism says that we
are just a collection of chemical.
399
:There's no answers whatever
to the question of how we
400
:should be able to capable.
401
:or poetry if we are simply
animated pieces of meat.
402
:so what's he, what's he saying?
403
:basically is that we need people
who believe and have the courage
404
:to act on those convictions.
405
:The worldview of atheistic materialism
that he has embraced most of his life can
406
:get there because we're just basically
animated pieces of meat where we're the
407
:result of chemical processes that had no.
408
:No rationality attached to them at all.
409
:That's that's all we are.
410
:So he's an atheist who at least sees
the value of Religion and society.
411
:I don't know if he was an atheist
when he wrote that he was most of
412
:his way Okay, that's so interesting.
413
:I crossed that quote and I was surprised
because I knew And Wilson, he was
414
:pretty harsh critic of, like, C.
415
:S.
416
:Lewis and many of his theistic arguments.
417
:Wow, uh, that's kind of how I knew him.
418
:So I was surprised when I read that.
419
:so the view that's consistent
is, make decisions and we hold
420
:beliefs based on how they help us
related to our evolutionary fitness.
421
:And so, because that's the goal, the
goal is not to find truth, the goal
422
:is To reproduce, and because of that
we're really in no position to make
423
:absolute statements related to really
any of these philosophical questions.
424
:But especially in the relation to
epistemology it's self defeating.
425
:That's so, that's so fascinating.
426
:And very thought provoking, because if
we want to give answers to some of
427
:these questions, then we got to think
through, okay, is my mind actually
428
:capable of giving some thoughts and
suggestions on these kinds of, topics?
429
:Right.
430
:Naturalism is a worldview.
431
:It's a philosophy.
432
:It's not something you have
immediate experience about,
433
:like the color of your shirt.
434
:It is making a statement about
the ultimate nature of reality.
435
:It's a metaphysical question.
436
:And yet, at its heart, it
undermines the ability to make
437
:metaphysical statements at all.
438
:That's the heart of what I'm arguing.
439
:Wow.
440
:If listeners want to go into
more depth, they can look at the
441
:arguments by Alvin Flantica, who
is a professional philosopher.
442
:I'm not a professional philosopher.
443
:I'm just a dabbler, but he has
developed this argument and written
444
:at least one book, maybe two.
445
:I think the second one he
responds to people who argue
446
:against him and push back.
447
:So there's some good
literature about this.
448
:This isn't just my idea.
449
:we'll drop that title in the
show notes and maybe put some
450
:links or something there.
451
:Sure.
452
:again, Darwin recognized as soon as
he developed and thought through the
453
:theory of evolution that it had a
challenge at its heart in terms of
454
:what that says about human knowledge.
455
:The first person I see really
developed this fully was Arthur
456
:Balfour in the Gifford Lectures.
457
:And then later a book that came out
of that called Theism and Humanism.
458
:And then C.
459
:S.
460
:Lewis carried that argument forward.
461
:I forget which chapter but
it's in his book, Miracles.
462
:And he goes about it a little
bit different way, his is a
463
:little bit more complicated.
464
:And then I think Alvin planned to get a
good job advancing that, uh, advancing
465
:the, this objection to naturalism.
466
:Yeah.
467
:Gotcha.
468
:Gotcha.
469
:so this, objection is not a new thing.
470
:It's been around for at
least a hundred years.
471
:Yes.
472
:it goes back at least a hundred years
to Balfour, maybe to Darwin because
473
:he had an inkling of the problem.
474
:But Alan Plantinga is the modern
theologian who has developed, I
475
:think he calls it the evolutionary
argument against naturalism.
476
:Okay.
477
:So evolution itself argues against
naturalism on naturalism's premises.
478
:So I'm sure if people Google that,
they'll find a number of articles
479
:or blog posts based on the E A N,
480
:all right.
481
:again, our goal here is not to tell
people what to believe or recriticize.
482
:What we're trying to do is say
there are some very basic families
483
:of worldviews that we're going
to interact with in this world.
484
:In our culture, especially, those
are theism and naturalism, or
485
:sometimes called materialism.
486
:And out of those two, we're
trying to argue that theism is at
487
:least as intellectually coherent
and valuable and satisfying as
488
:naturalism, in my opinion, more so.
489
:And because of that, it allows
a person to make a genuine faith
490
:commitment that they choose to
without sacrificing their intellect.
491
:That's our goal.
492
:We'll see if people feel like, we've
advanced towards that goal or not.
493
:Well, thanks so much for your time.
