Are atheists right to say that you can’t prove a universal negative?

I hear a lot of atheists complaining that they shouldn’t have any burden of proof because it is impossible to prove a universal negative, i.e. – “there is no God”.

Here’s a post from William Lane Craig about it.

Excerpt:

The first claim is, ironically, usually found on the lips of atheists, who thereby seek to excuse themselves from bearing any share of the burden of proof in the discussion. Usually, the claim is that a universal negative cannot be proved, and therefore the claim that “There is no God” is unprovable. The second claim is typically given as the reason why a universal negative cannot be proved: no matter how much knowledge you have acquired, there will always be more facts that you do not yet know, and perhaps the exception is among them. So one can never prove that there is no God. Perversely, this is somehow interpreted, not as an admission that atheism is indefensible, but as a demonstration that it is in no need of defense!

Unfortunately, the argument is misconceived on a couple of counts.

First, negative, universally quantified statements can be proved. We do this all the time. When we make statements about “all” or “none,” we are speaking about what is the case with respect to a certain domain. We are saying that all or none of the members of that domain have or has a certain property. If the domain is not too large, I can confidently make universally quantified affirmative and negative statements. For example, I am quite confident that “No U.S. Senator is a Muslim.” Or again, if I have a typical sample of the domain, I can make inductive inferences on the basis of the evidence from the sample to the whole, even if the whole domain is too large for me to canvass; for example, taking as my domain all the microbes on Earth, I can confidently assert, “No microbes have brains.”

Now someone might say that while it is admittedly true that negative, universal statements can sometimes be proven, still the point remains that in the case of God, the domain is too large and our sample too small to come to any negative conclusion. But those who propound this argument seem to think that the way one determines whether God exists is by taking a sort of universal survey to see if anything answering to the description of God exists somewhere out there. There are, however, other ways of coming to a knowledge of negative, universally quantified statements than doing an inductive survey.

For example, we can have knowledge of negative, universally quantified statements on the basis of things’ essential properties; for example, “No water molecules are composed of CO2.” (Even if something looked and behaved just like water but was made of CO2 , it still would not be water but just a look-alike substance.) Or if we could show that a notion is logically impossible, we would know that it does not exist; for example, “There are no married bachelors.” Significantly, many atheists have tried just this route to proving that God does not exist, arguing that the idea of a being which is all-powerful or all-knowing is logically incoherent.

[…]Second, the statement that “God does not exist” is not a universally quantified statement. When the theist asserts that “God exists,” the word “God” is being used as a proper name, not as a common noun. It is not a statement like “Dogs exist” but rather like “Lassie exists.” In order to prove that God does not exist, one need not prove that there are no gods whatsoever. Our interest is in one specific being, not in all the other beings which may have been imagined or worshipped throughout the world. So the claim that “God does not exist” is really a singular claim, like “Sherlock Holmes does not exist” or “Harry Potter does not exist.” No one thinks that negative, singular claims cannot be proven.

So there are two ways to disprove a universal negative. Look where you expect the thing to be evident, and show that the evidence is not there. For example, show evidence that the universe is eternal. You can’t have a Creator if you can show evidence that the universe is eternal. The second way is to show that the concept of God is logically contradictory, e.g. – that the concept of a “timeless person” is self-contradictory. Scholarly atheists try to do this, but this has not filtered down to the rank and file, which is why they still hold to these atheist slogans like “you can’t prove a universal negative”. Of course you can.

And finally, Craig concludes with some good advice:

The bottom line is that we have no choice but to go on the basis of the knowledge and evidence that we do have—just we do in all other affairs of life.

WorldGoneCrazy found a video of William Lane Craig answering the universal negative objection:

Rank and file atheists seem to be very keen on holding out for today’s scientific and historical data to be overturned by Star Trek theories of the future. But the more we study the good, scientific arguments for God’s existence, the harder it is for naturalism to account for it. I am talking about the origin of the universe, the cosmic fine-tuning, the habitability argument, the origin of life, the origin of phyla, scientific evidence for consciousness and free will (e.g. – mental effort) and so on. Not to mention other arguments like the moral argument and the minimal facts case for the resurrection of Jesus.

We have to decide on the data we have now. And the data we have now fits better with a theistic worldview than an atheistic worldview. I can imagine all kinds of data that would argue against Christian theism. Finding the bones of Jesus. The universe being eternal. Experimental evidence for the multiverse. A probable naturalistic scenario for the origin of life. Etc. Arguing against Christian theism is not hard, it just takes work. That’s why intelligent and informed atheists like Peter Millican and Austin Dacey can do it, but rank and file atheists want to talk about “I lack a belief in God” and “I can’t prove a universal negative”.

No one is asking atheists to prove anything, just as theists don’t prove anything. We are asking them to give logical arguments with premises that are supported by the evidence. And that’s what we expect theists to do, too. Once we have all the arguments and evidence on both sides, then people can decide for themselves. You don’t have to “prove” anything in a debate, you just have to state your case as persuasively as possible and the other side does the same, then people decide. Simple.

Here’s another post from Pastor Matt that I think offers some more helpful insight into how we should approach young people with Christianity. The point of this post is that relationships matter.

Excerpt:

When I was attending North Hollywood High in the fall of 1990, there was a kid in one of my classes who often followed me on my walk home to my apartment off of Magnolia Boulevard.  He did the Four Spiritual Laws and Roman Road presentation.  He spoke about he and his family’s faith in Jesus and wanted to know if I would come with them to church.  But he never asked a single question about me personally.  I always declined his invitations and eventually he moved on to someone else.

[…]Looking back, I had a very fuzzy understanding of the Gospel.  I (and I think many people who call themselves Christians) are what theologians call “semi-Pelagians.”  I believed anyone could come to the altar but if they wanted to continue to be welcomed in the pews, they had to clean up their act and do so almost overnight.  The culture of Christianity at large appeared to me to be that if you came to faith and continued to struggle with lust, a foul mouth or whatnot then there was just something wrong with you.  I felt the church was more about behavior modification than grace.

I needed someone who I knew loved me to sit down with me long before all of these problems arose, look me in the eye and tell me how easy and how difficult it is to be a Christian.  I needed someone cared for me to unpack 2 Corinthians 5:21 and point out that by being “in Christ” I would be judged by Christ’s perfect life instead of my own.  I needed to know that the faith is not about “keeping the rules” but about doing things and not doing certain things to show my love and gratitude to God for what He did for me.  I needed to be able to read the Bible, especially the Old Testament, in a way that always pointed to Jesus Christ.  I needed to understand that God has graciously given us the spiritual disciplines of fasting, prayer, serving the poor, worship, etc. to help me grow.  I needed to hear that all Christians struggle with sin and will, to a certain degree, until they go to be with the Lord or He returns to be with us.

I needed good theology, good spiritual practices, good apologetics and good relationships.  I needed  knowledge and it needed to come from someone who I knew loved me even though I was thoroughly unlovable.  You can’t just leave this to the church staff because they do not have to time to meet with everyone and people with a chip on their shoulder about the church (like I had) feel like they are just doing it as part of their job.  All young people in the church, especially the “troubled kids” need this.  It is a lot of work but anyone’s eternity is worth it, isn’t it?

I think that I do my best work away from the blog when I take on atheists or new Christians or Christians who want to grow one on one and focus on them for long periods of time. Sometimes, it’s talking to them on Skype. Sometimes, it’s rewards for doing well in school or in their Christian lives. But all the best work is done one on one. That’s when you really get a chance to get to know people and to care about them.

I think the most important thing you can tell a young Christian is to focus less on mere following of the rules. I always ask them more about making a plan for their lives that achieves something amazing for God’s kingdom, while still not breaking any of the rules. The following the rules is not the key thing to focus on. The key thing here is your relationship with God. So you should find out what needs doing, and just do it. If it’s intelligent design research, then do it. If it’s finding early NT manuscripts, then do it. If it’s working for the ADF defending religious liberty at the Supreme Court, then do it. If it’s becoming a Christian professor at a secular university, then do it. If it’s debating an atheist cosmologist, then do it. If it’s promoting the free market system which alleviates poverty, then do it. If it’s protecting democratic countries from aggression by being a soldier, then do it. Stop making Christianity a dull prison, and start making it a blank canvas for a masterpiece.

Don’t worry, he was an atheist then, and now he’s pastor Matt, thanks to God’s grace.

In this post Pastor Matt talks about why he was once an atheist.

Excerpt:

I am sometimes asked, by both skeptics and believers alike, why I was once an atheist and what convinced me to become a Christian.  I will answer the latter in another post but let me deal with the former now.

I am a “PK” or “preacher’s kid.”  My father served as the founding pastor of the largest church in southern Ohio.  It is a non-denominational, evangelical congregation that grew very quickly.

As a PK, I was privy to a lot of “inside information” and it was not encouraging.  I learned men and women who sang hymns with passion and shouted “Amen!” with gusto during the sermon were cheating on their spouse or on their taxes.

By the time I was a teenager I understood why those who called themselves Christians lived secret lives–they wanted to believe but really didn’t.  I understood because I became one of them.

I was an active member of an ’80′s evangelical youth group.  So, I rocked out to Stryper, had comedian Pat Hurley tapes and volunteered for the children’s ministry, which consisted of videotaping episodes of Superbook and The Flying House for the kids.  However, I actually seriously doubted if God even existed.

I was struggling with the normal sins of a teenager and begged for help in prayer.  I also petitioned God on a regular basis to feel His presence but that didn’t happen either.

I eventually came to the conclusion that Christianity simply didn’t work.  I declared myself an atheist at age fifteen and remained an unbeliever for the next ten years.

I ran away from home at age fifteen as well eventually making my way to Hollywood.  During those days I partied like it was 1999 (until 1997) and like Aldous Huxley is quoted as saying decades before, I came to not even want God to be real because even the possibility interfered with my desire to create my own morality.

Christianity is not something where you just profess it and suddenly you are automatically perfect. You get the gift of eternal life immediately by faith in Christ, but becoming more like Christ takes time. It’s easier to act consistently with the teachings of Christ if you have spent the time studying, practicing and growing as a Christian. You shouldn’t expect perfect behavior on day one – that is crazy. You should expect that as your beliefs become more solid, then your outward actions will change naturally. And often what you hear at home and in the church is not the best for finding truth through investigation and debate.

It would be terrible to have to put out “good” actions when you never settled the questions of what is true and how are we going to apply what is true in our own decisions. Sometimes, I think that young Christians face too much pressure to appear to be perfect when no one has been willing to help them work through the grounding for the behaviors they are expected to display. And I think a lot of the behaviors they are expected to display are either not important or not Biblical. Behaving like a  Christian should be natural – it should proceed from free inquiry, not dogmatism.

Now I’m skipping a lot, but here is his advice for people who were in his situation:

I’ll get to my conversion later but keep in mind: (1) just because a person attends a church, even if they are a PK, that he or she truly comprehends the Gospel because I didn’t a full understanding; (2) pastors need to constantly remind their parishioners that sin is easy and living for Christ is difficult because believers are part of a cosmic struggle; (3) the spiritual disciplines are invaluable especially so for young people; and (4) there are many solid arguments for the existence of God and few for materialism and all Christians deserve to know them.

I’ve spent some time mentoring young Christians who had fallen away for some period of  time, and I always make a point of asking them why. Their answer is usually something like this: “I knew that what I was doing was wrong, but I didn’t care because no one else cared.” The first thing to do with a person who is rebelling is to get in there and start to ask them questions and get involved in helping them to succeed in their lives. People do bad things because they feel that no one cares. So you better start caring for these young people, whether they are smart, dumb, pretty, ugly, poor, rich, popular, unpopular – it doesn’t matter. They all have souls, and they were all made to know God. Get in there and be real with them before they make a mess of their lives.
