The Existence of God
See Life’s Ultimate Questions, by Ronald NashChapters 12 & 13
Noetic Structure Definition: A person’s beliefs plus the
relationships among those beliefs Some beliefs serve as the basis or foundation of
other beliefs The foundation beliefs are called basic beliefs The beliefs based on them are called non-basic
beliefs Your noetic structure is different from mine
Beliefs about your past are different from beliefs about my past
Noetic structures are not wholly different Properly basic beliefs can be the same for two
persons
Some Properly
Basic BeliefsUnder the appropriate circumstances,
the appropriate belief is formed in us “I see a tree”
“I had eggs and bacon for breakfast”
“I am now at the edge of the Grand Canyon”
When you have a basic belief, it makes no sense for someone to say to you, “Prove it!”
Foundationalism’sStrengths
Believing that one’s noetic structure is based upon certain foundational beliefs (properly basic beliefs) provides answers to important questions
1. When should a belief be eliminated from a person’s noetic structure? When that belief is neither a properly basic belief
nor a belief properly grounded on a basic belief
Foundationalism’sStrengths
2. How should we judge the strength of a non-basic belief? In terms of the degree of
support it receives from basic beliefs
3. When should an argument end? When it arrives at properly
basic beliefs
Properly Basic Beliefs and God Christian philosopher Alvin Plantinga
teaches that Believing in God is a properly basic belief We have a tendency to form beliefs such
as “God is speaking to me” “God has created all this” “God disapproves of what I’ve done”
Christian philosopher Thomas Reid -- This tendency or belief disposition may be part of the image of God in every human
A Capacity to Apprehend God’s Existence
1. Begin by trusting the basic belief-forming dispositions with which you are endowed . . . Until reasons for revising them
arise2. If being appeared to by a pink rose
in the garden yields immediately the belief “There is a pink rose,”3. Then an encounter with God will yield the belief “God is real,” without deliberation or inference
Does God’s Existence Need to be Proved?
No. However, an argument for God’s
existence can be one of the belief-triggering conditions that results in the belief that God exists.
The Leaky Buckets Analogy
The Leaky Buckets AnalogyConsider these three
arguments1. All students have
long hair. Therefore, Smith has long hair.
Necessarily true? Probably true?
2. Smith is a student. Therefore, Smith has long hair.
Necessarily true? Probably true?
3. All students have long hair. Smith is a student.Therefore, Smith has long hair.
Necessarily true?
Probably true?
The Leaky Buckets Analogy
So, it’s possible to have a probably true argument formed from individually weak arguments
And it’s possible to derive a necessarily true argument from individually invalid arguments
Four Types of Arguments for God’s Existence
1. CosmologicalA. CausationB. Necessity C. Teleological
2. Prudential3. Experiential4. Moral
Cosmological
Everything’s moving. There must be a
Prime Mover.Everything’s been
caused by other things. There must be a First
Cause.
Every being is contingent.There must be a being that
is necessary.Every thing can be
graded.There must be a being that
is perfect.Every thing appears to
have been designed.There must be a designer.
“Look at the world (cosmos), and you will see that there is a God.”
Paley: The Watch Analogy
Walking in a field, you come across a stone “Where did this come from?” is an
absurd question to ask about the stone
Walking in a field, you come across a watch “Where did this come from?” is a
reasonable question to ask about the watch
The Anthropic Principle The universe seems to be designed
in such a way as to provide A home for humans (Gr. Anthropos) An observation post from which
humans can appreciate the grandeur of the universe The universe is strangely amenable to
rational inquiry on multiple integrated levels
The universe seems to be designed tutorially
The deep intelligibility of nature upon which science depends is the result of intelligent design
Guillermo Gonzalez
Prudential Pascal’s Wager
Mathematician and philosopher If you were a betting person,
which belief has the best odds going for it? A. “There is a God” B. “There is no God”
A. If correct, payoff is unlimited B. If correct, payoff is limited “There is a God” has the best
odds
Experiential “There is a God, because I have had an
experience of God.” Highly convincing for the one having the
experience. Not as convincing for anyone else.
Leo Tolstoy “Life is only bearable when I am believing that God
exists” William P. Alston
If it makes sense to believe a person exists when you have had shared experiences with that person,
Then it makes sense to believe that God exists if you have had shared experiences with God
Prayers answered Guidance given Comfort received
Moral There is a moral law of human nature
We didn’t invent it We don’t totally benefit from it We can’t escape it We don’t keep it
This law comes from Something Behind the Universe It is trying to communicate with
us, personally It must be a person himself
Mere Christianity -C.S. Lewis
Another Moral Argument
Unknown Source We live in a world containing
Incredible good Malevolent evil
Mere survival benefit is as inadequate an explanation for malevolent evil as it is for incredible good
There must be an incredibly good being against which a malevolently evil being is struggling
Three Types of Arguments Against the Existence of God
The Empirical Argument The Linguistic Argument Evidential Arguments
The Empirical ArgumentThe Invisible Gardener Story - Antony Flew (1950)
“Just how does what you call an invisible, intangible, eternally elusive gardener differ from an imaginary gardener or even from no gardener at all?"
"What would have to occur to constitute for you a disproof of the existence of God?"
The Linguistic Argument A.k.a. Theological Noncognitivism --
Michael Martin (also early William Alston):, “What kind of definition can we agree on which makes sense of the claim ‘There is a God?’” “How can an immaterial being
‘speak,’ or communicate messages in any way, or, indeed, act in any way?”
Evidential Arguments Victor Stenger: God -- The Failed
Hypothesis “Science proves that the universe is just as
one would expect it to be if there were no God.”
“The laws of physics and of nature do not suggest that a divine hand played a role in creating the universe.”
Sam Harris and Richard Dawkins offer similar arguments.
The Problem of Evil Charles Templeton Christopher Hitchens George H. Smith
The Problem: How can these three statements all be true?• God is all good.• God is all powerful.• Evil exists.
Why, then, does evil exist?“Either God isn’t all good, or God isn’t all
powerful.” “So, why should I believe in a being who either
isn’t strong enough or good enough to put an end to evil?”
