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
Speaker:

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.
