Philosophy of ReligionLecture 1: Intro

Dan TurtonPHIL104-2010

Page 2: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

What We’re NOT Asking

• Theological questions: – Usually presuppose that God exists

• Descriptive Questions: – E.g. When exactly did the Jewish and

Christian movements divide?; – Who wrote the Bible?; – What political and social structures

influenced the rise of Scientology

Page 3: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Kind of Thing We’re Asking

• Philosophical questions: – Usually makes no assumptions about the

existence of God

• Normative Questions: – E.g. Is it reasonable to have religious beliefs?– Under what conditions would one be justified in

believing (or disbelieving) in the existence of God?

– Should one be required to give reasons in support of religious judgments at all?

Page 4: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Main Question

• For the next 9 lectures, we are trying to answer the question:

• Is there a good justification for believing in the existence of God?

• Some major arguments and objections to them will be discussed

Page 5: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Words of Warning

Students in this class must respect the opinions of others when debating the question ‘Does God exist?’

Page 6: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Basic Vocab(ulary)

• Theist– believes there is a God

• Atheist– believes there is no God

• Agnostic– is neither a theist nor an atheist – could think it’s equally likely that God exists

and that God doesn’t– or perhaps hasn’t thought about the question

enough to form any beliefs on the matter

Advanced Vocab(ulary)

• Main Question: Is there a good justification for believing in the existence of God?

• Existence• God• Justification

Page 9: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Existence

• Primitive notion• To say that something (x) exists is not to say that:– there exists an idea or concept of x– x exists ‘in the mind’– x exists for me but (perhaps) not for you– it’s true for me that x exists but

(perhaps) it’s not true for you

Page 10: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

God• An absolutely perfect being• A first cause: a being that causes other things

to exist but is not itself caused to exist• An intelligent creator: a being that created the

universe• A being that possesses every property

attributed to a being named ‘God’ in the Bible (Torah, Koran, etc.)

• An invisible, vastly powerful intelligence who deserves to be worshiped and loved

• A being who sends those who do not believe in him to hell, and sends those who do believe in him to heaven

• A perfectly loving, all powerful, and all knowing being

Page 11: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Justification

• To say that one is justified in believing something is just to say that I have good reason to believe it

• Theoretical reasons• Practical reasons

Page 12: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

1. Intro2. Paley’s Design Argument3. More on the Design Argument4. Pascal’s Wager5. More on Pascal’s Wager6. The Argument from Evil7. More on the Argument from Evil8. Even more on the Argument from Evil9. Summary and exam revision

Page 13: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Faith• “The whole point is to have faith”

– If faith is believing in something without question, then how is faith in religion different to faith in fairies?

– You can have faith and still be interested in whether there is also good reason to believe that God exists

– You can even still have faith if you think that we have more reasons not to believe in god, than to believe in God

Page 14: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Religious Experience

• “I have experienced God and require no more evidence/ discussion that he exists”– So have millions of others, but lots of

them are aligned to different religions– Our experiential evidence can be

surprisingly deceiving– E.g. spiritual or religious experience

• Derren Brown

Page 15: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Arguments Against Religion in General

• “No one should believe in a religion because they were all made up by people”

• Being “managed” or “conveyed” by people doesn’t necessarily mean that a religion is false

• We are being more specific in this course anyway– Focus is just on God, not religion

Page 16: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Science

• “There is no scientific evidence for God, therefore God probably doesn’t exist”

• “It’s impossible to prove or disprove God’s existence with science, therefore we should be agnostic”

• Science is not the last word on the existence of God

Page 17: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Philosophy of ReligionLecture 2: Paley on Design

Dan TurtonPHIL104-2010

Page 18: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Intro

• William Paley 1743-1805• Watches appear to be

designed, so they probably have a designer

• The same goes for natural things, e.g. eyes

• God probably exists because he probably designed natural things

Page 19: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

How did the watch come to be?

• It’s so complex• All of it’s complex

parts seem to serve minor functions that allow the whole watch to do something useful

• It appears designed

Page 20: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Paley’s Argument from Design

(P1) It is an indisputable and yet remarkable fact that many watches appear to have been designed.

(P2) The best explanation for this appearance of design is that watches have been designed.

(P3) Inference to the Best Explanation: If an hypothesis H is the best explanation of an observation O, then it is rational to believe that H is true.

(C) Therefore, one should believe that watchmakers exist.

Page 21: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Inference to the Best Explanation

• A theory should minimize the number of entities it postulates

• A theory should be consistent with the evidence

• A theory should make reliable predictions• A theory should minimize the number of

unexplained coincidences• A theory should be, as far as possible,

simple and elegant

Page 22: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Inference to the Best Explanation

• The Knight Watchman’s dog spews watches all over the place and watch-sellers find them and sell them

• Have you ever met a watchmaker?

Page 23: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Watchmakers Exist

• Even if we have never met one, Paley thinks we do and should believe in them because of watches

• Most importantly, watches really appear to have been designed…

• Which gives us good reason to think that they have been designed

Page 24: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Design

• Intentionally created for some purpose(s)

• Therefore, requires a designer - an intentional creator

Page 25: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Appearance of Design

An object bears the marks of design if:1. It is structurally complex,2. It has a purpose or function, and3. It has the purpose it does in virtue

of its structural complexity.• Watches really appear to be

designed!

Page 26: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

(Bad) Reasons Watches Might Not be Designed

• Malfunction• Some components do

not help produce the main function

• You don’t understand how they work, so how can you say that they appear to be designed?

Page 27: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Paley’s Argument - Watches

(P1) It is an indisputable and yet remarkable fact that many watches appear to have been designed.

(P2) The best explanation for this appearance of design is that watches have been designed.

(P3) Inference to the Best Explanation: If an hypothesis H is the best explanation of an observation O, then it is rational to believe that H is true.

(C) Therefore, one should believe that watchmakers exist.

Page 28: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Paley’s Argument - Nature

(P1) It is an indisputable and yet remarkable fact that many natural things appear to have been designed

(P2) The best explanation for this appearance of design is that many natural things have been designed

(P3) Inference to the Best Explanation(P4) Therefore, one should believe that a

designer of natural things exists(P5) God is the designer of natural things (C) Therefore, one should believe that God

exists

Page 29: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Are Natural Objects Designed?

• Some certainly appear to be so

1. The eye is structurally complex,

2. It has a purpose or function, and

3. It has the purpose it does in virtue of its structural complexity.

Page 30: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Eyes

(P1) It is an indisputable and yet remarkable fact that eyes appear to have been designed.

(P2) The best explanation for this appearance of design is that eyes have been designed.

(P3) Inference to the Best Explanation: If an hypothesis H is the best explanation of an observation O, then it is rational to believe that H is true.

(C) Therefore, one should believe that eye-makers exist.

Page 31: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Paley’s Argument - Watches

(P1) It is an indisputable and yet remarkable fact that many watches appear to have been designed.

(P2) The best explanation for this appearance of design is that watches have been designed.

(P3) Inference to the Best Explanation: If an hypothesis H is the best explanation of an observation O, then it is rational to believe that H is true.

(C) Therefore, one should believe that watchmakers exist.

Page 32: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Eyes

(P1) It is an indisputable and yet remarkable fact that eyes appear to have been designed.

(P2) The best explanation for this appearance of design is that eyes have been designed.

(P3) Inference to the Best Explanation: If an hypothesis H is the best explanation of an observation O, then it is rational to believe that H is true.

(C) Therefore, one should believe that eye-makers exist.

Page 33: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Philosophy of ReligionLecture 3: More on Design

Dan TurtonPHIL104-2010

Page 34: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Today• Recap of Paley’s argument• Are eyes designed?

– Science: “no”• The fine-tuning variant of

the design argument– The chances of a universe

evolving that supports intelligent life is tiny

– So, God probably fine-tuned/designed the universe

Page 35: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

What is the Best Explanation for this Appearance?

• Theories are better if they:– minimize # of entities they postulate– are consistent with the evidence– make reliable predictions– minimize unexplained coincidences– simple and elegant

• Is there a better explanation for eyes appearing to designed… than them being designed? (P2)

Page 36: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Evolution by Natural Selection

• Darwin: natural objects will evolve to bear the marks of design if the following four conditions are met:

1. There is variation among the objects/traits

2. Traits are inherited3. Variation in traits is random4. The objects/organisms

compete

Page 37: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

But the Eye? Really!?!

• "To suppose that the eye, with all its inimitable contrivances… could have been formed by natural selection, seems, I freely confess, absurd in the highest degree."  Charles Darwin, The Origin of Species

• The eye gave him a “cold shudder”

Page 38: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Yes, It Could Have Evolved!

• Reason tells me, that despite it being hard to imagine, many subtle random changes exposed to the pressure of selection over time can lead to the evolution of a perfect and complex eye from a simple and imperfect one. Furthermore, there exist examples of the steps along the way. Paraphrase of Charles Darwin, The Origin of Species

• From the same page!!

Page 39: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Dawkins on How to Climb Mount Improbable

• How can we get to (explain) the eye on top of Mount Improbable?

• To get to the eye in one leap is impossible

• But, if we take lots of slow steps, then Climbing Mount ImprobableDoesn’t seem thathard

Page 40: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Slow Steps to the Eye

• The eye didn’t just evolve in one step or by random

• A slow process of organisms competing over thousands of iterations gave a selective advantage to various stages of proto eyes– Note that the process involves random

mutation, but it is not a ‘random process’

Page 41: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

• Light-sensitive cells

• Information sent to brain

• Pin-hole camera

• Lens for focusing

• Etc

Page 42: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Evidence is Out There

• Link to more on evolution

Page 43: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Fine-Tuning Argument

(P1) It is an indisputable and yet remarkable fact that the universe appears to have been designed

(P2) The best explanation for this appearance of design is that the universe has been designed

(P3) Inference to the Best Explanation(P4) Therefore, one should believe that a

designer of the universe exists(P5) God is the designer of the universe (C) Therefore, one should believe that God

exists

Page 44: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Does the Universe Appear to be Designed 1?

• If the initial explosion of the big bang had differed in strength by as little as 1 part in 1060, the universe would have either quickly collapsed back on itself, or expanded too rapidly for stars to form. In either case, life would be impossible.

• Calculations indicate that if the strong nuclear force, the force that binds protons and neutrons together in an atom, had been stronger or weaker by as little as 5%, life would be impossible.

Page 45: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Does the Universe Appear to be Designed 2?

• Calculations by Brandon Carter show that if gravity had been stronger or weaker by 1 part in 1040, then life-sustaining stars like the sun could not exist. This would most likely make life impossible.

• If the neutron were not about 1.001 times the mass of the proton, all protons would have decayed into neutrons or all neutrons would have decayed into protons, and thus life would not be possible.

Page 46: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Does the Universe Appear to be Designed 3?

1. The universe is structurally complex,

2. It has a purpose or function (supporting intelligent life), and

3. It has the purpose or function it does in virtue of its structural complexity.

So P1 seems correct – the universe appears to be designed

Page 47: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Best Explanation for the Universe’s Appearance of Design?

• God is all-powerful and all-knowing– He and only he has what it takes to

design and create this marvelous universe

• The universe can support life as we know it by chance– Different physical laws may well have

allowed for the existence of a different kind of universe and other kinds of life

Page 48: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Intergalactic Lotto• The odds of winning

intergalactic lotto are 999billion to 1

• Everyone is automatically enrolled

• You win intergalactic lotto• Did chance or divine

creation cause your win?

Page 49: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Best Explanation for the Universe’s Appearance of Design?

• God-centered explanation postulates one more entity

• The scientific explanation involves some pretty big and fairly poorly explained coincidences

• Which is the best explanation?

Page 50: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Philosophy of ReligionLecture 4: Pascal’s Wager

Dan TurtonPHIL104-2010

Page 51: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Today• Decision Theory primer• Pascal’s Wager• Practical reason for

being a theist (of a particular type)

• Because of heaven and hell, the expected utility of belief in god outweighs disbelief

Page 52: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Primer on Decision Theory

• We are practically rational to the extent that we do what’s in our best interests.

• Utility is a measure of our happiness or preference satisfaction.

• Decision Theory: we do what’s in our best interests when (and only when) we perform actions that maximize our expected utility

Page 53: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Decision Theory tries to be Precise

• In order to determine which action maximizes expected utility, we need to set up a consequence matrix, which includes:

– all relevant choices available to the agent (in the left column)

– all relevant possible outcomes after the agent has acted (in the top row)

– the probability of each outcome-choice pair (in parentheses next to the utility values)

– the utility of each outcome-choice pair (in each of the remaining empty boxes)

Page 54: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

‘The One’

• So, you have met ‘the one’ in your PHIL104 lecture

• You are agonizingly in love with him/her

• What should you do??

Page 55: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

A Consequence Matrix

Getting ‘the one’ to go out with you

You don’t get to go out with them – (“no”)

You get to go out with them – (“yes”)

Expected Utility

Ask them [0.8] [0.2]

Don’t ask them

[0.99] [0.01]

How likely are

outcomes given the decision?

Must add up to 1 going across

Ask them [0.8]*-20 = -19.2

[0.2]*50 = 10

Don’t ask them

[0.99]*-10 = -9.01

[0.01]*75 = 0.75

Calculate the

expected utility for

each choice/outcome pair

-9.01 + 0.75 = -8.26

Compare the expected utility for

each choice

Page 58: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Decision Theory Helps Us…

• … To see how dire our lovestruck position is– Neither of the two options

available to us will produce positive utility!

• The best choice is not to ask though– It minimises our disutility

(suffering)

• But, maybe we should make the decision in a couple of days…

Page 60: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Wrong Question

• Pascal thinks that ‘what is God?’ and ‘does God exist?’ are the wrong questions– These questions involve the infinite and

so are beyond us• He thinks we should ask ‘should we

believe in God or not?’– Theoretical reasons are inconclusive,

but– We have practical reasons to believe

Page 61: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

How Will You Bet?

• You have to play• If you choose A, I flip a coin

– ‘Heads’ = you get the worst existence possible and it continues for ever

– ‘Tails’ = you have a normal unrestricted life

• If you choose B, I flip a coin– ‘Heads’ = you get the best existence

possible and it continues for ever– ‘Tails’ = you have a normal life, but

slightly more restricted than normal

Page 62: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Pascal’s Wager

Should I believe in God?

God Exists God doesn’t exist

Expected Utility

Believe [0.5]*∞ = ∞

[0.5]*10 = 5

∞ + 5 = ∞

Don’t believe

[0.5]*10 = 5

[0.5]*10 = 5

5 + 5 = 10

Page 63: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Standard Presentation of Pascal’s Wager

Should I believe in God?

God Exists(p≠0)

God doesn’t exist

Expected Utility

Believe [p]*∞ [1-p]*-10 = ∞

Don’t believe

[p]*-∞ [1-p]*10 = -∞

Page 64: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Upshot?• If the standard Pascalian setup of the

wager is correct, then we have a good (practical) reason to believe in God

Should I believe in God?

God Exists(p≠0)

God doesn’t exist

Expected Utility

Believe [p]*∞ [1-p]*-10 = ∞

Don’t believe

[p]*-∞ [1-p]*10 = -∞

Page 65: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

I Can’t Make Myself Believe in God!

1. I can’t force myself to believe in God!• Pascal: you should learn from those who have

converted to theism

2. Even if I could, then God wouldn’t appreciate my only believing in him for my own best interests!

• Perhaps God doesn’t mind as long as you believe

• It may start like this, but turn into belief regardless of your interests

Page 66: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Philosophy of ReligionLecture 6: The Argument

from Evil

Dan TurtonPHIL104-2010

Page 67: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Today• Based on Dostoevsky’s

‘Rebellion’…• Being clear about what

God and evil are• Asking why God might

allow evil• Concluding that even if

there is a reason for the evil, it’s probably not good enough

Page 68: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

What is Evil?

• All things equal, a state of affairs is evil if it involves the suffering of an innocent

• The more suffering of innocents in any situation, the more evil it is

• There can be other types of evil

Page 69: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Varieties of Evil

• We can distinguish between the following kinds of evil:• Natural evil v.

human evil• Necessary evil v.

unnecessary evil• Mild evil v.

horrendous evil

Page 70: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

What is God?

• God is, by definition, omnibenevolent, omnipotent and omniscient• An individual x is omnibenevolent if and

only if it is perfectly loving• (all good/perfectly good)

• An individual x is omnipotent if and only if it can do anything • (all powerful)

• An individual x is omniscient if and only if it knows everything• (all knowing)

Page 71: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Argument from Evil

(P1) If God exists, he is omnibenevolent, omnipotent and omniscient. [By Definition]

(P2) An omnibenevolent being would prevent any unnecessary evil if she could and knew how.

(P3) An omnipotent being could prevent all unnecessary evil.

(P4) An omniscient being would know all about unnecessary evils and how to prevent them.

(P5) Therefore, if God exists, there is no unnecessary evil. [From (P1), (P2), (P3) & (P4)]

(P6) But there is unnecessary evil. [Evidential Premise]

(C) Therefore, God does not exist. [From 5 & 6]

Page 72: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

P6) Dostoevsky’s Examples of Unnecessary Horrendous Evil

• A 5-y.o. girl is mistreated by her parents, beaten, forced to eat her own excrement etc.

• A young boy is ripped apart by hounds in front of his mother

• A soldier cuts an unborn baby out of it’s mother’s womb, throws it in the air and catches it with his bayonet

Page 73: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Is that Suffering Unnecessary?

• Ivan discusses a few reasons why it might be considered necessary, but rejects them:

1. We need evil to understand good2. Humans allowed evil by choosing free

will3. All humans must suffer for the mistakes

of our ancestors4. God has a plan which makes this

suffering necessary for us all to share harmony in the end

Page 74: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

We Need Evil to Understand Good

• Evil and good are like two sides of a coin– you can’t have a 1-sided coin– could you know dark without light?– Good would be meaningless normalcy

without evil• Ivan: If the price to know goodness is

so high, then I would prefer we knew nothing of goodness– Perhaps we could know goodness by evil

occurring to adults only

Page 75: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Evil is a Necessary Consequence of Human Freewill

• God gave humans the power to choose to be good or evil– We would be like ants without this

choice– A consequence is that sometimes we

choose to be evil

• Ivan?: If such great evil results from our freewill, then God should never have let us have it

Page 76: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

We All Must Suffer for the Mistakes of our Ancestors

• Adam needn’t have eaten the apple, but he did– This made him guilty, and– Us guilty too, since we are of him

• Ivan: Our real-world sense of justice does not allow guilt to be inherited– Why does God allow it?– It doesn’t make sense to us

Page 77: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

God’s Plan Requires the Evil

• We cannot fathom God’s infinite goodness, power and intellect– All suffering that we see is necessary for the

ultimate good of us all being united in harmony– (Or some other great good)

• Ivan: it’s unfair that some innocents suffer in this plan, esp. children!– I won’t go to a heaven where the mother of the

killed baby/child forgives the evil people who caused innocents to suffer for their own pleasure!

Page 78: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Is that Suffering Unnecessary?

1. We need evil to understand good2. Humans allowed evil by choosing

free will3. All humans must suffer for the

mistakes of our ancestors4. God has a plan which makes this

suffering necessary for us all to share harmony in the end

• Any other ideas how to make the evils we see necessary?

Philosophy of ReligionLecture 7: More on the

Argument from Evil

Dan TurtonPHIL104-2010

Page 80: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Today• Recap

– Argument from Evil• Mackie

– Evil and God are logically incompatible

• Rowe– Evil and God are not logically

incompatible, – But evil provides a good

reason to be an atheist– But, we should still be friendly

Page 81: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Mackie on Evil• Thinks the argument from evil shows

that most forms of theism are internally inconsistent

• Theists believe all of these 3:– God is all-powerful– God is all-good– There is evil in the world

• But no more than 2 of these could be true at any one time

Page 82: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Mackie Considers Responses

• He finds that all of them don’t fully work

• They generally alter the definitions of the important terms

Page 83: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Evil is an Illusion

• There is no evil, just the illusion of evil because…– E.g. – Change is required for evil and nothing

actually ever changes– All of our worldly perceptions are illusory

• This illusion sure seems mean (evil) though!

Page 84: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

God’s Plan Requires the Evil

• We cannot fathom God’s infinite goodness, power and intellect– All apparent evils are necessary for the

ultimate good - being united in harmony– So apparent evils are really just part of

the overall good• But apparent evils are actually a bit

evil– If we can imagine a way to bring about

the great good without evil, then an all-powerful being could do it

Page 85: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Good cannot Exist without Evil

• But, God is omnipotent, so he can make good exist without evil

• Omnipotence = being able to do anything that is logically possible

• Good is logically possible without evil (unlike relative terms e.g. bigger/smaller)

Page 86: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

We Cannot Appreciate Good without Evil

• Our perceiving suffering in the world creates a juxtaposition with the goods we see, making them much better– The net result is more goodness overall

• Surely there is enough evil in our history and imaginations to juxtapose the goods we see?

• Only a tiny amount of non-horrendous suffering is needed for this and we see more than that

Page 87: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Some Evil is Needed for Expression of Virtues

• The whole world is better if there is evil because it allows for heroism, compassion, benevolence etc.

• But evil also allows vices of cruelty, malevolence, callousness, cowardice etc

• There doesn’t seem to be a net gain here• And why let innocents like children be the

target of vices?

Page 88: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Evil is Due to Freewill 1

• Is it better on the whole to have freewill?– How much evil can we bear for freewill?– Is there more or less evil than that?

• ‘Free’ choices are constrained already– Why do we not have the freewill to choose from

just the neutral and good options?– Imagine if we never thought of the possibility of

doing evil– If God is all-powerful, then he either controls our

choices or they are random– If we really have full freewill, then God is not all-

powerful

Page 89: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Evil is Due to Freewill 2

• If we really have full freewill, then God is not all-powerful– God could prevent willful acts of human

evil but refrains from doing so… • But why would he do this?

– because freedom to carry out evil deeds outweighs the evil consequences?

• But this is not justice as we know it!

Page 90: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Paradox of Omnipotence

• Can an omnipotent God create rules that restrict itself?

• Can God make a rock so heavy that it is un-liftable? …YES– Can God lift that rock? …YES– Contradiction

• Can God make people with complete freedom of choice? …YES– Can God control those people? …YES– Contradiction

Page 91: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

What about Natural Evil?

• Natural evil is not caused by freewill– Is there another reason why natural

evils are necessary?

• Consistent laws of nature required to allow freewill to operate properly– Couldn’t consistent laws of nature

prevent all natural suffering?– E.g. natural force-fields for babies

Page 92: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Rowe• Just because we can’t see why an evil

might be necessary does not mean that it cannot be necessary

• Therefore, the Argument from Evil does not logically prove that an all-knowing, -powerful and -good God does not exist

• But, not knowing a good reason for why evil is necessary does give us a reason to be atheists

• Is it reasonable to believe that all of the evil in the world is necessary for some greater good? …No

Page 93: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Varieties of Atheism

• Unfriendly Atheism:– Theistic belief is not rationally justifiable

• Indifferent Atheism:– Agnostic about whether theists’ belief in

God is rationally justifiable• Friendly Atheism:

– Some theists’ belief in God is rationally justified

Page 94: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Friendly Atheism

• Can a Friendly Atheist really think that they are justified in not believing in God while theists might well be justified in believing in God?

• We can think of the Argument from Evil as a reason not to believe in God and the Fine-Tuning Design Argument as a reason to believe

• Throw in religious experience for the theist but not the atheist and both seem to be reasonably justified in their beliefs

Argument from Evil

Dan TurtonPHIL104-2010

Page 96: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Today• Recap

– Mackie, Rowe and ‘Ivan’ on the Argument from Evil

• Howard-Snyder– There are reasons why evil might

be necessary, some of which we can’t even imagine

– Do these reasons (taken together) justify the huge amount of evil in the world?

– We cannot be sure that they do not

– We should not even say it is likely that they do not

Page 97: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Howard-Snyder

• Not all of the article will be covered• He discusses some theodicies

(explanations of why evil is necessary)

• But, he thinks theists don’t really need them because the argument from evil contains a bad noseeum inference

Page 98: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Evil and Suffering

• “the history of our planet is… stuffed with undeserved, horrific evil and suffering”

• Intentional human evil– A child dies from abuse by its parents every 6

hours in the US

• Unintentional human evil– On a boiling hot day, a Kentucky professor left

his child in the back of his car all day

• Natural evil– Children and animals suffer because of famine,

disease and natural disasters

Page 99: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Two Problems• The practical problem of evil

– Assumes God exists– Observing evil may cause a theist to

despair or rebel against God – Like ‘Ivan’: “put God on trial for

negligence and gross incompetence”

• The theoretical problem of evil– Does not assume that God exists– Is evil evidence that we should not be

theists?– “Philosophical twaddle” is his focus

Page 100: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Why Does God Permit Evil?

• Why do so many innocents suffer?– And why do they suffer so much?

• When asked like this, an assumption is hidden

• The questioner assumes that:– If we cannot give a good reason for why

God permits this suffering, then there is no good reason

– This assumption is wrong

Page 101: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Is God only Semi-Potent?• Theists might say that God

is not all-powerful• Problem:

– How can a being be powerful and knowledgeable to create and sustain the universe but not be powerful enough to prevent evil?

– Is there something special about evil that makes him powerless to stop it?

Page 102: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Why the Evil, God?

• “If there was some greater good that could not possibly occur unless evil were permitted, it might well figure in God’s reason to permit evil.”

• Theodicies:– Attempts to explain why God permits

evil

Page 103: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Punishment Theodicy

• God is justified in punishing evildoers

• But what about natural evil?

• This response doesn’t get anywhere without reincarnation

Page 104: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Counterpart Theodicy

• Good requires evil to exist and vice versa

• But God is omnibenevolent– Just before God created the universe,

only he existed– God is all-good (no evil)– Therefore, good can exist without evil

Page 105: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Free Will Theodicy

• Self-determination is the greater good for which we must countenance evil

• But why not block others from harm without evil-doers realising?– Then I can still determine my character

and actions, but no innocents suffer as a result

Page 106: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

What about Natural Evil?

• The free choices of nonhuman people (e.g. Satan & his demons) causes all natural evils

• But, science can better explain natural evils than Satan and demons can– This will not convince any atheists

Page 107: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Natural Law Theodicy

• Without rigid laws of nature, we would live in a random world where fruitful exercise of freewill would be impossible– I want to hug you but my limbs act so

erratically that I poke you in the eye and crush your ribs

– The natural laws that govern the movement of physical bodies also result in earthquakes and landslides

Page 108: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

“The Reason”• There are reasons why evil might be

necessary– Let’s call all of them together “The

Reason”

• “would The Reason justify God in permitting so much evil rather than a lot less?”– E.g. same but no dementia or Ebola

virus or genocide– The Reason does not justify so much evil

Page 109: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

The Argument from Amount

1) There is no reason that would justify God in permitting so much evil rather than a lot less

2) If God exists, then there must be such a reason

C) So, God does not exist

• 2 is usually conceded… but is 1 true?

Page 110: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Noseeum Inferences• I can’t see it• So, it’s probably not there• Good noseeum inferences

– Looking for milk in the fridge

• Bad noseeum inferences– Looking for slugs in the garden

• Is it reasonable to believe that we are very likely to see (comprehend) the thing in question?

Page 111: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Noseeum ‘The Reason’

• So far as we can tell, there is no reason for God to permit so much evil

• Therefore, there probably is no reason for God to permit so much evil

• Is this a reasonable inference to make?– Are we likely to see (comprehend) The

Reason if there is one?

Page 112: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Chances of Comprehending The Reason

• There are several reasons to doubt that we could understand it

• We have finite intellect– We’re unable to understand infinite goods

• There are probably lots of goods we are yet to discover– We’re limited by evolution in this

• The Reason is probably too complex for us to understand– Great goods are often complex e.g. wine

Page 113: Philosophy of Religion Lecture 1: Intro Dan Turton PHIL104-2010.

Is there Unnecessary Evil?

• And how sure can we be?• Does our inability to see a good reason for

so much evil justify belief that there isn’t one?

• Where is the burden of proof here?– Definitely on anyone trying to convert

someone else either way

• We can imagine a world with lots of goods, and without so much evil… – but what of the greater goods that we don’t

know about?– That depends… are there any?
