Does God’s omniscience conflict with human free will?

Here’s the question from Come Reason Ministries.

Excerpt:

Hello,

Christian doctrine holds that God is all knowing (1 John 3:20), and humans have free will (Deuteronomy 30:19 is my favorite example). however, at my favorite apologetics debate board, I have seen skeptics raise an objection to these points several times. the basic logic behind their arguments is this:

  1. A being with free will, given two options A and B, can freely choose between A and B.
  2. God is omniscient (all-knowing).
  3. God knows I will choose A.
  4. God cannot be wrong, since an omniscient being cannot have false knowledge.
  5. From 3 and 4, I will choose A and cannot choose B.
  6. From 1 and 5, omniscience and free will cannot co-exist.

I have read many counter-arguments from apologetics sites, but they were either too technical (I couldn’t understand them), or not satisfying. so, I was wondering what would your input be on this issue?

Thank you,

Justin

Ever heard that one? Here’s Lenny Eposito’s answer:

Hi Justin,

Thanks for writing. This is a great question as it shows how even those who appeal to logic can have biases that blind them. Let’s examine this argument and see if it follows logically.

Premises 1 and 2 in your outline above are the main premises to the argument and are not disputed. The Christian worldview argues that every human being is a free moral agent and is capable of making choices simply by exercising their will, not under compulsion or because of instinct. Also, it is a long held doctrine of Christianity that God is all-knowing. The Bible says that God knows “the end from the beginning (Isaiah 46:10).” For omniscience to be truly knowledgeable it must be correct knowledge, so premise number 4 is also granted.

However, point number 5 is where the logic falters. Those who argue in this manner make the mistake of thinking that because God possesses knowledge about a specific matter, then he has influenced it. That does not follow at all. Just because God can foresee which choice you will make, it does not mean you couldn’t still freely choose the other option.

Let me give you an example. I have a five year old son. If I were to leave a chocolate chip cookie on the table about a hour before dinner time and my son was to walk by and see it, I know that he would pick up the cookie and eat it. I did not force him to make that decision. In fact, I don’t even have to be in the room at all. I think I know my son well enough, though, to tell you that if I come back into the kitchen the cookie will be gone. His act was made completely free of my influence, but I knew what his actions would be.

In examining the argument, the assumption is made in premise 3 that because God knows I will choose A somehow denies me the choice of B. That is the premise that Christianity rejects. Omniscience and free will are not incompatible and it is a non-sequitor to claim otherwise.

Thank you Justin for this interesting question. I pray that you will continue to defend the gospel of our Lord and may He continue to bless you as you seek to grow in Him.

That’s a great answer and should work in ordinary conversations.

More technical

J.W. Wartick maps out the arguments more fully with symbolic logic here on his Always Have A Reason blog. But I’ll just excerpt the gist of it.

Excerpt:

It is necessarily true that if God knows x will happen, then x will happen. But then if one takes these terms, God knowing x will happen only means that x will happen, not that x will happen necessarily. Certainly, God’s foreknowledge of an event means that that event will happen, but it does not mean that the event could not have happened otherwise. If an event happens necessarily, that means the event could not have happened otherwise, but God’s foreknowledge of an event doesn’t somehow transfer necessity to the event, it only means that the event will happen. It could have been otherwise, in which case, God’s knowledge would have been different.

[…]Perhaps I could take an example. Let’s say that I’m going to go to classes tomorrow (and I do hope I will, I don’t like missing classes!). God knows in advance that I’m going to go to classes tomorrow. His knowledge of this event means that it will happen, but it doesn’t mean that I couldn’t choose to stay in and sleep for a while, or play my new copy of Final Fantasy XIII, or do something more useless with my time. If I chose to, say, play Final Fantasy XIII (a strong temptation!), then God simply would have known that I would play FFXIII. His knowledge does not determine the outcome, His knowledge is simply of the outcome.

If we choose A, God would foreknow A. If we choose B, God would foreknow B. His foreknowledge of our choices is contingent on our making free choices.

I had to learn symbolic logic and Bayes’ theorem in college for my computers science degrees, and it’s pretty useful for understanding these philosophers. Philosophy is a lot like computer science, at least for analytical philosophy.

William Lane Craig debates Victor Stenger: Does God Exist?

This debate took place on March 1, 2010 at Oregon State University.

In this debate, Victor Stenger does affirm his belief that the universe could be eternal in his second rebuttal (1:02:30), thus denying the standard Big Bang cosmology. He also denies the law of conservation of energy and asserts that something can come from nothing in his concluding speech (1:33:50). He also caused the audience to start laughing when he said that Jesus was not moral and supported slavery. There is almost no snark in this summary. Instead, I quoted Dr. Stenger verbatim in many places. I still think that it is very entertaining even without the snarky paraphrasing.

The debate includes 30 minutes of Q&A with the students.

Here is the MP3 file for the audio.

Here’s the video of the debate:

Dr. Craig’s opening speech:

  • The ontological argument
  • The contingency argument
  • The cosmological argument
  • The moral argument
  • The resurrection of Jesus (3-fact version)
  • Religious experience

Dr. Stenger’s opening speech:

  • There is no scientific evidence for God’s existence in the textbooks
  • There is no scientific evidence for God acting in the universe
  • God doesn’t talk to people and tell them things they couldn’t possibly know
  • The Bible says that the Earth is flat, etc.
  • There is no scientific evidence that God answers prayers
  • God doesn’t exist because people who believe in him are ignorant
  • Human life is not optimally designed and appears to be the result of a blind, ad hoc evolutionary process
  • The beginning of the universe is not ordered (low entropy) but random and chaotic
  • It’s theoretically possible that quantum tunneling explains the origin of the universe
  • The laws of physics are not objectively real, they are “our inventions”
  • Regarding the beginning of the universe, the explanation is that something came from nothing*
  • Nothing* isn’t really nothing, it is “the total chaos that we project existed just before the big bang”
  • If something has no structure, then “it is as much nothing as nothing can be”
  • Consciousness is explainable solely on the basis of material processes
  • There are well-informed, rational non-believers in the world and God would not allow that

Dr. Craig’s first rebuttal:

Stenger’s argument that there is no objective evidence for God’s existence:

  • First, it is not required that God rely only on objective evidence in order to draw people to himself (Alvin Plantinga)
  • Second, God is not required to provide evidence to everyone, only to the people who he knows would respond to him
  • Third, Craig gave lots of objective evidence, from science, history and philosophy
  • Stenger asks for certain evidence (answered prayers, prophecy, etc.), but Craig presented the evidence we have

Stenger’s argument that the balance of energy is zero so “nothing” exists:

  • if you have the same amount of assets and liabilities, it doesn’t mean that nothing exists – your assets and liabilities exist
  • Christopher Isham says that there needs to be a cause to create the positive and negative energy even if they balance
  • the quantum gravity model contradicts observations
  • the vacuum is not the same as nothing, it contains energy and matter
  • the BVG theorem proves that any universe that is expanding must have a beginning

Stenger’s argument that mental operations can be reduced to physical operations:

  • mental properties are not reducible to physical properties
  • epiphenomenalism: is incompatible with self-identity over time
  • epiphenomenalism: is incompatible with thoughts about other things
  • epiphenomenalism: is incompatible with free will
  • substance dualism (mind/body dualism) is a better explanation for our mental experience
  • God is a soul without a body
Dr. Stenger’s first rebuttal:

Craig’s cosmological argument:

  • Craig’s premise is “everything has a cause”, but quantum mechanics has causeless events
  • There are speculative theories about how something could have come into being uncaused out of nothing
  • “I don’t know of a single working cosmologist today who believes there was a singularity prior to the Big Bang”
  • “If there wasn’t a singularity then there’s no basis for arguing that time began at that point”
  • “There’s no reason from cosmology that we know of that the universe can’t be eternal”
  • “When I talk about an eternal universe, I mean a universe that has no beginning or end”
  • The Hartle-Hawking model doesn’t have a beginning
  • “There was no violation of energy conservation by having a universe coming from nothing”
  • “The universe could have come from a previous universe for example or even just from a region of chaos”
  • The paper by Vilenkin is counteracted by other papers (he doesn’t specify which ones)

Craig’s moral argument:

  • Dr. Craig is arguing from ignorance
  • But morality can be decided by humanity just like governments pass laws, and that’s objective
  • Dr. Craig has too little respect for the human intellect
  • I don’t need to tell me that slavery is wrong
  • The Bible supports slavery
  • Atheists can behave as good as theists
  • Morality just evolved naturally as an aid to survival

Craig’s resurrection argument:

  • No Roman historians wrote about the execution of Jesus but none of them did
  • The empty tomb is doubtful because it is only mentioned in the gospels, not by Paul
  • John Dominic Crossan says there was no empty tomb
  • Christianity only survived because the Roman empire thought that they were useful

Dr. Craig’s second rebuttal:

Craig’s cosmological argument:

  • There is no reason to prefer an indeterministic interpretation of quantum mechanics
  • Dr. Stenger himself wrote that deterministic interpretations of quantum mechanics are possible
  • The vacuum in quantum mechanics is not nothing
  • The quantum vacuum he proposes cannot be eternal
  • The cosmological argument does not require a singularity
  • The Hartle-Hawking model is from 1983
  • Hawking says that there is a beginning of space and time after that model
  • The Hartle-Hawking model does still have a beginning of time – the model is not eternal
  • The BVG theorem that requires a beginning for expanding universes is widely accepted among cosmologists

Craig’s moral argument:

  • Stenger redefined objective to mean that most people agree with it – but that’s not what objective means
  • Objective means right and wrong whether anyone accepts it or not
  • Richard Dawkins himself says that on atheism there is “no evil and no good” – why is he wrong?
  • Even Dr. Stenger says that morality is the same as passing laws – it’s arbitrary and varies by time and place
  • But on his view, right and wrong are the same as deciding which side of the road to drive on
  • But somethings really are right and some things are really wrong

Craig’s resurrection argument:

  • Josephus is a Roman historian and he wrote about Jesus, for example
  • There were four biographies of Jesus are the best sources for his life
  • The scholars that Stenger mentioned are on the radical fringe

Dr. Stenger’s second rebuttal:

Knowledge and the burden of proof:

  • Dr. Craig has to bear the burden of proof, not me – because his claim is more “extravagant”
  • “I don’t have to prove that a God was not necessary to create the universe”
  • “I don’t have to prove that a God did not design the universe and life”
  • “I don’t have to prove that the universe did not have a beginning”
  • “I don’t have to prove that God did not provide us with our moral sense”
  • There are a lot of books written about how morality evolved naturally
  • “I don’t have to prove that the events surrounding the supposed resurrection of Jesus did not take place”
  • Bart Ehrman says that the gospels are generally unreliable (Note: Ehrman accepts all 3 of Craig’s minimal facts)
  • Just because people are willing to die for a cause, does not make their leader God, e.g. – the Emperor of Japan

Aesthetic concerns about the universe:

  • I don’t like dark matter and I wouldn’t have made the universe with dark matter
  • I don’t like the doctrine of penal substitution
  • I don’t like the doctrine of original sin
  • I don’t like the heat death of the universe

Dr. Craig’s conclusion:

The case for atheism:

  • Dr. Stenger had two arguments and he has to support his premises
  • Dr. Craig addressed his two arguments and each premise and Dr. Stenger never came back on it

The contingency argument:

  • Dr. Stenger has dropped the refutation of this argument

The cosmological argument:

  • The theoretical vacuum he proposes cannot be eternal

The moral argument:

  • He asserts that things are wrong, but there is no grounding for that to be objective on atheism

The resurrection of Jesus:

  • There are surveys of scholars on the empty tomb and 75% of them agree with it
  • Bart Ehrman agrees with all 3 of the minimal facts that Dr. Craig presented
  • Ehrman’s objection to the resurrection is not historical: he’s an atheist – he thinks miracles are impossible

Religious experience:

  • No response from Dr. Stenger

Dr. Stenger’s conclusion

The cosmological argument:

  • “I argued that we have very good physical reasons to understand how something can come from nothing”
  • “There is a natural tendency in the universe… to go from.. simpler thing to the more complicated thing”
  • The transition from a vapor to a liquid to ice shows how something could come from nothing
  • “It cannot be proven that the universe had a beginning”

The moral argument:

  • Objective morality, which is independent of what people think, could be developed based on what people think
  • “Jesus himself was not a tremendously moral person… he had no particular regard for the poor… he certainly supported slavery… he was for the subjugation of women” (audience laughter)

The resurrection argument:

  • Bart Ehrman says that the majority of the gospels are unreliable

Religious experience:

  • I don’t see any evidence that there is anything more to religious experience than just stuff in their heads

God’s purpose of the world should be to make people feel happy:

  • God could have made people feel happier
  • God could have made people not die
  • God could could have made the universe smaller: it’s too big
  • God could have made it possible for humans to live anywhere “even in space”

Why Christian parents get nervous about evidence

Homeschooling mother Dr. Lydia McGrew explains why Bible-believing Christians are uneasy with the use of evidence on her blog What’s Wrong With The World. (H/T Eric Chabot)

Excerpt:

4) The idea that, if a young person gets deeply interested in Christian evidence, he will go out on the Internet (or at his public high school or secular college) seeking giants to slay and will get overwhelmed. Again, this worry has merit as a sociological matter. That can certainly happen.

That is why we should say loud and clear to Christians interested in this topic: Don’t do that! What do I mean? Just this: Being committed to investigating the evidence for Christianity does not mean that one has to find out every possible thing that anyone has ever said about or against Christianity and know the answer to it. That would be impossible because of the sheer bulk of (ultimately unpersuasive) objections which skeptics can bring up as though they were real problems.

In this context the words of George Horne, an 18th century bishop, from his Letters on Infidelity, are wise and helpful. (Emphasis added.)

In the thirty sections of their pamphlet, they have produced a list of difficulties to be met with in reading the Old and New Testament. Had I been aware of their design, I could have enriched the collection with many more, at least as good, if not a little better. But they have compiled, I dare say, what they deemed the best, and, in their own opinion, presented us with the essence of infidelity in a thumb-phial, the very fumes of which, on drawing the cork, are to strike the bench of bishops dead at once. Let not the unlearned Christian be alarmed, “as though some strange thing had happened to him,” and modern philosophy had discovered arguments to demolish religion, never heard of before. The old ornaments of deism have been “broken off” upon this occasion, “and cast into the fire, and there came out this calf.” These same difficulties have been again and again urged and discussed in public; again and again weighed and considered by learned and sensible men, of the laity as well as the clergy, who have by no means been induced by them to renounce their faith.

[snip]

Many and painful are the researches sometimes necessary to be made, for settling points of that kind. Pertness and ignorance may ask a question in three lines, which it will cost learning and ingenuity thirty pages to answer. When this is done, the same question shall be triumphantly asked again the next year, as if nothing had ever been written upon the subject.

And a bit later:

5) The unspoken fear that Christianity cannot stand up to scrutiny and doesn’t really have good evidential support.

Here I do not blame the parents, but not because I share the unspoken fear. I do not blame them, because in most cases no one has ever taught them otherwise. How many pastors and priests have really taught apologetics to their congregations, or even offered such studies as an option? Too few. How many courses on sharing your faith have explicitly taught people not to get involved in responding to questions and objections but just to “share their experience” because “no one can argue with that”? Too many. It’s no wonder then that the congregation comes away with the sneaking suspicion that our Christian faith is no better grounded than Mormonism and that we, like they, must depend chiefly on the burning in the bosom.

And one can always push the blame further back. Perhaps the pastors weren’t taught Christian evidences at their seminaries.

In fact, I would not be surprised if all too many theologians who give high-falutin’ rationalizations for being anti-evidentialist are actually making a virtue out of what they deem to be a necessity. Since they don’t think Christian faith is founded on fact, they might as well make up some profound-sounding theological theory that tells us that it shouldn’t be.

When Nathanael asks Philip, “Can any good thing come out of Nazareth?” Philip simply says, “Come and see.” (John 1:46) And he brings him to Jesus. If you as a parent or mentor to the young are opposed to the study of Christian evidences partly because deep down you suspect that they aren’t very good, I can only say to you as well, “Come and see.”

I blogged about this tendency of church leaders to make a virtue out of laziness and ignorance before.

Here’s a snip:

Suppose a pastor or campus group leader wants to avoid having to learn physics and cosmology, or the minimum facts case for the resurrection, or how to respond to apparently gratuitous suffering, or the problem of religious pluralism. Suppose he thinks that Christianity, if it is about anything, is about his feeling happy and comfortable with a minimum of effort and work. So, he diligently avoids reading apologetics, because learning evidence is hard work. He avoids watching debates on God’s existence and the resurrection, because this is hard work. He avoids conversations with people who do study these things, and implies that there is something wrong with them for studying these things. He endeavors to conceal his laziness and ignorance and cowardice from his flock with much pious God-talk and fervent praise-hymn-singing.

Eventually, some member of his church asks him to go for lunch with an actual non-Christian family member. The pastor agrees and when he meets the unbelieving family member, he has nothing at all to say about typical challenges that unbelievers face. He has no knowledge of evolution, the problem of evil, the hiddenness of God, or the hallucination theory. He has never read a single atheist, and never read a single piece of evidence to refute them from Christian scholars. He lacks humility, refusing to admit that other Christian scholars may know more than he does because they have studied other areas. Needless to say, he fails to defend God’s reputation to the non-Christian. What will he say to the members of his flock about his failure? How will he justify his obstinate refusal to do what everyone else in the Bible does when confronting non-believers?

Well, consider this review of a recent book that defends the Gospels and the historicity of the resurrection by one such fideist pastor.

He writes:

There are, however, two significant shortcomings to the book.

First, Cold-Case Christianity places far too much emphasis on the role of extrabiblical sources. No doubt there is a legitimate role for biblical archaeology and extrabiblical writing from antiquity. Christianity is, after all, a faith firmly rooted in human history. But there is a grave danger when truth is suspended because of an apparent lack of corroboration from extrabiblical sources. And Wallace, I’m afraid, wanders too close to this dark side of apologetics.

All of chapter 12, for instance, is devoted to proving the Gospels have external corroborative evidence—“evidence that are independent of the Gospel documents yet verify the claims of the text” (183). Wallace then addresses the historicity of the pool of Bethesda and makes another worrying statement: “For many years, there was no evidence for such a place outside of John’s Gospel. Because Christianity makes historical claims, archaeology ought to be a tool we can use to see if these claims are, in fact, true” (201-202, emphasis added).

In other words, Wallace seems to suggest we cannot affirm the truth of the Gospel accounts without the stamp of approval from archaeology and other extrabiblical sources. Such reasoning is dangerous, not least because it cannot affirm the inerrancy of the Bible. But also, it places the final court of appeal in the realm of extrabiblical sources rather than of God’s all-sufficient, all-powerful Word.

That is a textbook definition of fideism – that belief is somehow more pious and praiseworthy the less evidence we have. And the best way to have less evidence is to study nothing at all, but to just make a leap-of-faith in the dark. Of course, a leap-of-faith can land you anywhere – Islam, Mormonism. Presumably this pastor is like the Mormons who eschew all evidence and prefer to detect the truth of Mormonism by “the burning of the bosom” which happens when people read the all-sufficient, all-powerful Book of Mormon. His view of faith is identical to theirs, and 180 degrees opposed to the Bible. He has made his leap-of-faith, and that leap-of-faith is not accountable to arguments and evidence. His faith is private and personal, based on his own feelings. He considers it blasphemous to have to demonstrate what he believes to those who disagree with him. Where is this in the Bible? It’s nowhere. But it is everywhere in anti-intellectual Christian circles.

[…]I think that Christians are much better off following the example of authentic Christian pastors like R.C. Sproul, who, in a conference on evangelism, invited Dr. Stephen C. Meyer to present multiple lines of evidence from mainstream science to establish the existence of God. The only reason not to take this approach is laziness, which leads to ignorance, which leads to cowardice. And failure. It is pastors like Pastor Bungle above who are responsible for the great falling away from Christianity that we are seeing when we look at young people. Pastors who pride themselves in refusing to connecting the Bible to the real world, with evidence and with policy analysis, are causing young people to abandon the faith.

I think that many people who reject Christianity can point to a general impression that they got from Pastor Bungle and his ilk that faith is somehow different from other areas of knowledge and that it was morally praise worthy to insulate faith from critical thinking and evidence. Pastor Bungle could never justify his view by using the Bible, but a lot of church leaders have that view regardless of whether it’s Biblical or not.

The really troubling thing that I see again and again in the church is when pastors base all of their opposition to behaviors like abortion and gay marriage on Christianity. This effectively makes it impossible to do anything about these issues in the public square, because Christians are then taught to have nothing persuasive to say on these issues to non-Christians. It’s like pastors are more interested in striking a pious pose with their congregations instead of studying secular arguments and evidence so they can equip Christians to actually solve the problem.
