William Lane Craig: must the cause of the universe be a person?

I am posting this to prepare everyone for tonight’s debate between Sean Carroll and William Lane Craig. The cause of the universe is sure to come up in tonight’s debate, which is at 7 PM Central, 8 PM Eastern time!

I expect Dr. Carroll to raise many objections to the kalam cosmological argument in tonight’s debate. One that will come up for sure is the objection that the cause of the universe need not be a person (i.e. – the cause need not be personal).

Here’s a post from my friend Fred Woodbridge, who blogs at IFCONFIG blog, where he quotes from Dr. Craig’s book “Reasonable Faith”. The quote contains three arguments for why the cause of the universe must be personal.

Quote:

First, as Richard Swinburne points out [in The Existence of God], there are two types of causal explanation: scientific explanations in terms of laws and initial conditions and personal explanations in terms of agents and their volitions. For example, if I come into the kitchen and find the kettle boiling, and I ask Jan, “Why is the kettle boiling?” she might answer, “The heat of the flame is being conducted via the copper bottom of the kettle to the water, increasing the kinetic energy of the water molecules, such that they vibrate so violently that they break the surface tension of the water and are thrown off in the form of steam.” Or she might say, “I put it on to make a cup of tea. Would you like some?” The first provides a scientific explanation, the second a personal explanation. Each is a perfectly legitimate form of explanation; indeed, in certain contexts it would be wholly inappropriate to give one rather than the other. Now a first state of the universe cannot have a scientific explanation, since there is nothing before it, and therefore it cannot be accounted for in terms of laws operating on initial conditions. It can only be accounted for in terms of an agent and his volitions, a personal explanation.

Second, the personhood of the cause of the universe is implied by its timelessness and immateriality. The only entities we know of which can possess such properties are either minds or abstract objects, like numbers. But abstract objects do not stand in causal relations. Indeed, their acausal nature is definitive for abstract objects; that is why we call them abstract. Numbers, for example, cannot cause anything. Therefore, the transcendent cause of the origin of the universe must be of the order of mind.

Third, this same conclusion is also implied by the fact that we have in this case the origin of a temporal effect from a timeless cause. We’ve concluded that the beginning of the universe was the effect of a first cause. By the nature of the case, that cause cannot have any beginning of its existence or any prior cause. Nor can there have been any changes in this cause, either in its nature or operations, prior
to the beginning of the universe. It just exists changelessly without beginning, and a finite time ago it brought the universe into existence. Now this is exceedingly odd. The cause is in some sense eternal and yet the effect which it produced is not eternal but began to exist a finite time ago. How can this be? If the necessary and sufficient conditions for the production of the effect are eternal, then why isn’t the effect eternal? How can all the causal conditions sufficient for the production of the effect be changelessly existent and yet the effect not also be existent along with the cause? How can the cause exist without the effect?

One might say that the cause came to exist or changed in some way just prior to the first event. But then the cause’s beginning or changing would be the first event, and we must ask all over again for its cause. And this cannot go on forever, for we know that a beginningless series of events cannot exist. There must be an absolutely first event, before which there was no change, no previous event. We know that this first event must have been caused. The question is: How can a first event come to exist if the cause of that event exists changelessly and eternally? Why isn’t the effect co-eternal with its cause?

To illustrate: Let’s say the cause of water’s freezing is subzero temperatures. If the temperature were eternally below zero degrees Centigrade, then any water around would be eternally frozen. If the cause exists eternally, the effect must also exist eternally. But this seems to imply that if the cause of the universe existed eternally, the universe would also have existed eternally. And this we know to be false.

One way to see the difficulty is by reflecting on the different types of causal relations. In event/event causation, one event causes another. For example, the brick’s striking the window pane causes the pane to shatter. This kind of causal relation clearly involves a beginning of the effect in time, since it is a relation between events which occur at specific times. In state/state causation one state of affairs causes another state of affairs to exist. For example, the water’s having a certain surface tension is the cause of the wood’s floating on the water. In this sort of causal relation, the effect need not have a beginning: the wood could theoretically be floating eternally on the water. If the wood begins to float on the water, then this will be a case of event/event causation: the wood’s beginning to float is the result of its being thrown into the water. Now the difficulty that arises in the case of the cause of the beginning of the universe is that we seem to have a peculiar case of state/event causation: the cause is a timeless state but the effect is an event that occurred at a specific moment in the finite past. Such state/event causation doesn’t seem to make sense, since a state sufficient for the existence of its effect should have a state as its effect.

There seems to be only one way out of this dilemma, and that is to say that the cause of the universe’s beginning is a personal agent who freely chooses to create a universe in time. Philosophers call this type of causation “agent causation,” and because the agent is free, he can initiate new effects by freely bringing about conditions which were not previously present. For example, a man sitting changelessly from eternity could freely will to stand up; thus, a temporal effect arises from an eternally existing agent. Similarly, a finite time ago a Creator endowed with free will could have freely brought the world into being at that moment. In this way, the Creator could exist changelessly and eternally but choose to create the world in time. By “choose” one need not mean that the Creator changes his mind about the decision to create, but that he freely and eternally intends to create a world with a beginning. By exercising his causal power, he therefore brings it about that a world with a beginning comes to exist. So the cause is eternal, but the effect is not. In this way, then, it is possible for the temporal universe to have come to exist from an eternal cause: through the free will of a personal Creator.

On the basis of a conceptual analysis of the conclusion implied by the kalām cosmological argument, we may therefore infer that a personal Creator of the universe exists, who is uncaused, beginningless, changeless, immaterial, timeless, spaceless, and unimaginably powerful. This, as Thomas Aquinas was wont to remark, is what everybody means by “God.”

I’m sure that Dr. Carroll will raise many other objections to the kalam argument. If Dr. Carroll is clever, he might also object that the notion of  timeless person is incoherent, that the notion of an unembodied mind is incoherent, that we don’t know that non-physical minds can cause effects in the physical world, that matter can’t come into being out of nothing, that even if effects in the physical universe have causes that doesn’t mean the universe as a whole has to have a cause, and that the notion of causation doesn’t make sense unless time has already started. But these are objections that Dr. Craig answered in his debate with Peter Millican, so they shouldn’t phase him.

Ready for the Craig-Carroll debate? review the BGV theorem and quantum tunneling

UPDATE: My brief summary of the Craig-Carroll debate is now posted. I may do a longer one next week if they release audio/video. Otherwise, the short summary will be it.

In the debate between William Lane Craig and Peter Millican, William Lane Craig presented the arguments for theism, including his standard Kalam cosmological argument which asserts that the universe had a beginning. The atheist, Peter Millican, raised several objections to the notion of a beginning to the universe. But Craig was able to establish the beginning of the universe by appealing to something called the Borde-Guth-Vilenkin theorem. This theorem is new – but it is worth learning about.

First, let’s review Craig’s cosmological argument:

A1) The origin of the universe

  1. The universe began to exist.
  2. If the universe began to exist, then the universe has a transcendent cause.
  3. The universe has a transcendent cause.

The origin of the universe is confirmed by philosophical arguments and scientific evidence.

There cannot be an actual infinite number of past events, because mathematical operations like subtraction and division cannot be applied to actual infinities.

The Borde-Guth-Vilenkin (BGV) proof shows that every universe that expands must have a space-time boundary in the past. That means that no expanding universe, no matter what the model, can be eternal into the past.

Even speculative alternative cosmologies do not escape the need for a beginning.

The cause of the universe must be transcendent and supernatural. It must be uncaused, because there cannot be an infinite regress of causes. It must be eternal, because it created time. It must be non-physical, because it created space. There are only two possibilities for such a cause. It could be an abstract object or an agent. Abstract objects cannot cause effects. Therefore, the cause is an agent.

So he appealed to the Bord-Guth-Vilenkin theorem right from the start in order to guarantee a space-time boundary in the past – i.e., a beginning of the universe, which is his premise 1.

Ok, now let’s take a look at some videos on this theorem.

The Borde-Guth-Vilenkin theorem, explained

From the Craig-Millican debate:

The BGV theorem also came up in the Craig-Krauss debate:

See my summary of the Craig-Krauss debate for more. I also wrote about after the debate, where it was shown that Krauss misrepresented the BGV theory to favor naturalism. So that’s why we all need to be familiar with what it says and how it is misrepresented by naturalists in debates. That will prepare us to understand what is happening in tonight’s debate.

I also expect quantum tunneling to come up in tonight’s debate, and here is a clip from Dr. Craig’s first debate with Lawrence Krauss at North Carolina State University.

Upcoming Greer-Heard forum on cosmology, featuring Sean Carroll and William Lane Craig

(Video: William Lane Craig debates the fine-tuning argument with Duke University philosopher Alex Rosenberg)

Christian Post reports on what promises to be one of the best debates in William Lane Craig’s career.

Excerpt:

The debate over God’s existence heats up next week as leading physicist and atheist Sean Carroll is pitted against William Lane Craig, a top theologian and philosopher, to discuss their views about philosophy, cosmology, and the role of God and the cosmos.

The two experts will debate on Feb. 21 under the theme “God and Cosmology: The Existence of God in Light of Modern Cosmology.” Organizers announced Wednesday that the event will be held at New Orleans Baptist Theological Seminary as part of a Greer-Heard Point-Counterpoint Forum in Faith and Culture Weekend Conference. Modern cosmology is dominated by the Big Bang theory, which attempts to bring together observational astronomy and particle physics.

“Though Carroll is as fiercely anti-theistic as other cosmologists I have debated, he differs in being philosophically informed and civil in demeanor,” Craig wrote in a statement about the event.

Craig is a philosopher, professor, author and founder of ReasonableFaith.org, a web-based ministry “whose purpose is to provide, in the public arena, an intelligent and articulate perspective about the existence of God.” He has debated some of the most notable atheists, including the late Christopher Hitchens, Richard Dawkins, and, most recently, Lawrence Krauss. Some 250,000 people have watched the Craig-Krauss dialogues since they took place last August in Australia.

Over the years, Craig has developed “Eight Reasons for God.” These form his case for theism, showing that God is the best explanation for why anything exists at all; the origin of the universe; the application of mathematics to the physical world; the fine-tuning of the universe for intelligent life; intentional states of consciousness in the world; objective moral values and duties in the world; the historical facts concerning Jesus’ resurrection; and personal experience of God.

Sean Carroll is a physicist at the California Institute of Technology. His research focuses on theoretical physics and cosmology, especially the origin and constituents of the universe. He has contributed to models of interaction between dark matter, dark energy, and ordinary matter; alternative theories of gravity; and violations of fundamental symmetries. He has appeared on TV shows including “The Colbert Report” and Through the Wormhole with Morgan Freeman, and frequently serves as a science consultant for film and television. He is the author of several books including the upcoming The Particle at the End of the Universe.

Each has selected two commentators to round out the discussion, philosophers Tim Maudlin and Alex Rosenberg on Carroll’s tag team and philosopher Robin Collins and physicist James Sinclair on Craig’s. A follow-up discussion is planned for that Saturday.

“I selected the physicist James Sinclair, with whom I co-authored the article on the kalam cosmological argument in the Blackwell Companion to Natural Theology, and Robin Collins, who is writing what will be the definitive book on the fine-tuning of the universe,” said Craig. “Carroll and I will be afforded the opportunity to give brief responses to each of their papers.

“There will also be opportunity for audience interaction with all the participants. Not only will the entire proceedings be video-recorded, but the transcript of the debate, papers, and responses will be published by Fortress Press. So this promises to be a very substantive and important engagement. It will also be live-streamed on the Internet, so you can join in if you’d like.”

Dr. Carroll’s blog post about the debate

Dr. Carroll posted about this upcoming debate on his blog, and it seems like he is is going to be a fine opponent for Dr. Craig.

Excerpt: (links removed)

Next month I’ll be doing something related, although under quite different circumstances. On February 21 I’ll be debating William Lane Craig at the Greer-Heard Forum, an event sponsored by the New Orleans Baptist Theological Seminary. It will actually be a two-day event; a debate between Craig and me on Friday night, and follow-ups on Saturday from other speakers — Tim Maudlin and Alex Rosenberg for Team Naturalism, Robin Collins and James Sinclair for Team Theism.

[…]William Lane Craig (or WLC as we call him in the business) is of course a very well-known figure, largely for his many public debates, on theism/atheism as well as on various other specific theological issues. As far as debating goes: he’s very good at it! If his debates were being judged by a panel of experts as in an intercollegiate debate tournament, he would have a very good record indeed. This has led many people to conclude that atheists just shouldn’t debate him at all, or at least not until they have devoted 10,000 hours to learning how to be a good debater.

Daniel Dennett warned me that, as soon as word got out that I would be debating WLC, I would be deluged with opinions and unsolicited advice. Which is great! Always happy to hear other perspectives, although I don’t promise to actually follow any of the advice. I won’t reproduce the various emails I’ve received, but here are a few very different perspectives online: Jerry Coyne, Luke Barnes (and another), and Wintery Knight. (WK is relatively restrained, but others predict “pummelings,” presumably for me.)

Dr. Carroll explained his goals for the event:

Just so we’re clear: my goal here is not to win the debate. It is to say things that are true and understandable, and establish a reasonable case for naturalism, especially focusing on issues related to cosmology. I will prepare, of course, but I’m not going to watch hours of previous debates, nor buy a small library of books so that I may anticipate all of WLC’s possible responses to my arguments. I have a day job, and frankly I’d rather spend my time thinking about quantum cosmology than about the cosmological argument for God’s existence. If this event were the Final Contest to Establish the One True Worldview, I might drop everything to focus on it. But it’s not; it’s an opportunity to make my point of view a little clearer to a group of people who don’t already agree with me.

Recently, Dr. Carroll debated Christian philosopher Hans Halvorson, who is a professor at Princeton University, and Hugh Ross was in attendance. In a podcast, Dr. Ross said that Carroll was a gentleman, and it was a good debate, although he wanted Halvorson to disagree with Carroll more. (You can watch the “debate” here, although it really wasn’t a debate because Halvorson didn’t engage Carroll for the most part). Reasons to Believe has since pulled the podcast. However, I was able to find it, (I am a software engineer!), and I’ve posted it here. I have no idea why they pulled it, because it was a good review. If you want a good introduction to the issues they’ll be debating from a particle physicist, check out this recent lecture by Dr. Michael Strauss.

The two duelists choose their seconds

My understanding is that Dr. Carroll has already made one mistake. He selected Alex Rosenberg (see video above) as a respondent. Dr. Rosenberg is not a good spokesman for naturalism, and in his debate with Dr. Craig, he did very poorly. A better wingman would have been someone like Graham Oppy or Quentin Smith. Dr. Carroll’s other choice (Tim Maudlin) looks solid, though.

On Dr. Craig’s side, he’s chosen Robin Collins and James Sinclair. Collins recently had a chapter in “Debating Christian Theism” (Oxford University Press, 2013) and Collins and Sinclair both had chapters in “The Blackwell Companion to Natural Theology” (Wiley-Blackwell, 2009). Collins is an engaging public speaker, and I featured a lecture by him on the fine-tuning argument in this post.

Please pray that God would reach out to Dr. Carroll and for other non-theists listening to the debate so they can see that there are good reasons for them to rethink their views about God.

Dr. Luke Barnes previews the debate

If you would like to read some comments from an accomplished cosmologist, check out these posts (post one, post two, post three, post four) on Dr. Luke Barnes’ Letters to Nature blog. You might remember him because I wrote about his paper critical of atheist physicist Victor Stenger in this blog post. Note that Barnes’ paper has now been published in a peer-reviewed journal. The journal is published by Cambridge University.
