William Lane Craig lectures against naturalism at the University of St. Andrews, Scotland

Note: if you have heard Dr. Craig’s arguments against naturalism before, then I recommend jumping right to the Q&A time, which starts 72 minutes in.

About Dr. William Lane Craig:

William Lane Craig (born August 23, 1949) is an American analytic philosopher, philosophical theologian, and Christian apologist. He is known for his work on the philosophy of time and the philosophy of religion, specifically the existence of God and the defense of Christian theism. He has authored or edited over 30 books including The Kalam Cosmological Argument (1979), Theism, Atheism and Big Bang Cosmology(co-authored with Quentin Smith, 1993), Time and Eternity: Exploring God’s Relationship to Time (2001), and Einstein, Relativity and Absolute Simultaneity (co-edited with Quentin Smith, 2007).

Craig received a Bachelor of Arts degree in communications from Wheaton College, Illinois, in 1971 and two summa cum laudemaster’s degrees from Trinity Evangelical Divinity School in Deerfield, Illinois, in 1975, in philosophy of religion and ecclesiastical history. He earned a Ph.D. in philosophy under John Hick at the University of Birmingham, England in 1977 and a Th.D. underWolfhart Pannenberg at the University of Munich, Germany in 1984.

Here is the full lecture with Q&A: (2 hours)

Summary:

  • Naturalism defined: the physical world (matter, space and time) is all that exists
  • Dr. Craig will present 7 reasons why naturalism is false
  • 1) the contingency argument
  • 2) the kalam cosmological argument
  • 3) the fine-tuning of the universe for intelligent life
  • 4) the moral argument
  • 5) the ontological argument
  • 6) the resurrection of Jesus
  • 7) religious experience

The Q&A time starts around 1:12:00.

Dr. Craig does mention an 8th argument early in the Q&A – the argument from the non-physicality of mental states (substance dualism), which is an argument that I find convincing, because a materialist conception of mind is not compatible with rationality, consciousness and moral agency. He gets a couple of questions on the moral argument early on – one of them tries to put forward an evolutionary explanation for “moral” behaviors. There’s another question the definition of naturalism. There is a bonehead question about the non-existence of Jesus based on a Youtube movie he saw – which Craig responds to with agnostic historian Bart Ehrman’s book on that topic. There’s a question about God as the ground for morality – does morality come from his will or nature. Then there is a question about the multiverse, which came up at the physics conference Dr. Craig attended the day before. There is a good question about the Big Bang theory and the initial singularity at time t=0. Another good question about transfinite arithmetic, cardinality and set theory. One questioner asks about the resurrection argument. The questioner asks if we can use the origin of the disciples belief as an argument when other religions have people who are willing to die for their claims. One of the questioners asks about whether the laws of nature break down at 10^-43 after the beginning of the universe. There is a question about the religious experience argument, and Craig has the opportunity to give his testimony.

I thought that the questions from the Scottish students and faculty were a lot more thoughtful and respectful than at American colleges and universities. Highly recommended.

Chad Meister: can atheists make sense of morality?

Philosopher Chad Meister takes a look at the attempts of some prominent atheists to make rational sense of morality within their worldviews.

Here is the abstract:

Atheists often argue that they can make moral claims and live good moral lives without believing in God. Many theists agree, but the real issue is whether atheism can provide a justification for morality. A number of leading atheists currently writing on this issue are opposed to moral relativism, given its obvious and horrific ramifications, and have attempted to provide a justification for a nonrelative morality. Three such attempts are discussed in this article: Walter Sinnott-Armstrong’s position that objective morality simply “is”; Richard Dawkins’s position that morality is based on the selfish gene; and Michael Ruse and Edward Wilson’s position that morality is an evolutionary illusion. Each of these positions, it turns out, is problematic. Sinnott-Armstrong affirms an objective morality, but affirming something and justifying it are two very different matters. Dawkins spells out his selfish gene approach by including four fundamental criteria, but his approach has virtually nothing to do with morality—with real right and wrong, good and evil. Finally, Ruse and Wilson disagree with Dawkins and maintain that belief in morality is just an adaptation put in place by evolution to further our reproductive ends. On their view, morality is simply an illusion foisted on us by our genes to get us to cooperate and to advance the species. But have they considered the ramifications of such a view? Each of these positions fails to provide the justification necessary for a universal, objective morality—the kind of morality in which good and evil are clearly understood and delineated.

[…]We can get to the heart of the atheist’s dilemma with a graphic but true example. Some years ago serial killer Ted Bundy, who confessed to over thirty murders, was interviewed about his gruesome activities. Consider the frightening words to his victim as he describes them:

Then I learned that all moral judgments are “value judgments,” that all value judgments are subjective, and that none can be proved to be either “right” or “wrong”….I discovered that to become truly free, truly unfettered, I had to become truly uninhibited. And I quickly discovered that the greatest obstacle to my freedom, the greatest block and limitation to it, consists in the insupportable “value judgment” that I was bound to respect the rights of others. I asked myself, who were these “others”? Other human beings, with human rights? Why is it more wrong to kill a human animal than any other animal, a pig or a sheep or a steer? Is your life more to you than a hog’s life to a hog? Why should I be willing to sacrifice my pleasure more for the one than for the other? Surely, you would not, in this age of scientific enlightenment, declare that God or nature has marked some pleasures as “moral” or “good” and others as “immoral” or “bad”? In any case, let me assure you, my dear young lady, that there is absolutely no comparison between the pleasure I might take in eating ham and the pleasure I anticipate in raping and murdering you. That is the honest conclusion to which my education has led me—after the most conscientious examination of my spontaneous and uninhibited self.

While I am in no way accusing atheists in general of being Ted Bundy-like, the question I have for the atheist is simply this: On what moral grounds can you provide a response to Bundy? The atheistic options are limited. If morality has nothing to do with God, as atheists suppose, what does it have to do with? One response the atheist could offer is moral relativism, either personal or cultural. The personal moral relativist affirms that morality is an individual matter; you decide for yourself what is morally right and wrong. But on this view, what could one say to Bundy? Not much, other than “I don’t like what you believe; it offends me how you brutalize women.” For the personal relativist, however, who really cares (other than you) that you are offended by someone else’s actions? On this view we each decide our own morality, and when my morality clashes with yours, there is no final arbiter other than perhaps that the stronger of us forces the other to agree. But this kind of Nietzschean “might makes right” ethic has horrific consequences, and one need only be reminded of the Nazi reign of terror to see it in full bloom. This is one reason why thoughtful atheists, such as Christopher Hitchens, Walter Sinnott-Armstrong, Richard Dawkins, Sam Harris, Daniel Dennett, and others don’t go there.

But what about cultural moral relativism—the view that moral claims are the inventions of a given culture? Most thoughtful atheists don’t tread here either, and this is one reason why: If right and wrong are cultural inventions, then it would always be wrong for someone within that culture to speak out against them. If culture defines right and wrong, then who are you to challenge it? For example, to speak out against slavery in Great Britain in the seventeenth century would have been morally wrong, for it was culturally acceptable. But surely it was a morally good thing for William Wilberforce and others to strive against the prevailing currents of their time and place to abolish the slave trade. For the cultural moral relativist, all moral reformers—Wilberforce, Martin Luther King, Jr., even Jesus and Gandhi, to name a few—would be in the wrong. But who would agree with this conclusion? Thankfully, most leading atheists agree that moral relativism is doomed.

So what do they affirm? Here are three accounts that recent atheists have defended: (1) objective morality simply “is,” (2) morality is based on the selfish gene, and (3) morality is an evolutionary illusion. Let’s take a brief look at each of them.

William Lane Craig on the unexpected applicability of mathematics to nature

You might remember that Dr. Craig used a new argument in his debate with Lawrence Krauss in Melbourne, Australia.

My notes on the debate record it thus:

The unreasonable effectiveness of mathematics:

  • The underlying structure of nature is mathematical – mathematics is applicable to nature
  • Mathematical objects can either be abstract objects or useful fiction
  • Either way, there is no reason to expect that nature should be linked to abstract objects or fictions
  • But a divine mind that wants humans to understand nature is a better explanation for what we see

And now Dr. Craig has expanded on it in the Q&A section of his Reasonable Faith web site.

The question:

Dear Dr Craig

Firstly can I thank you for all your work. My faith in Christ has been enormously strengthened through studying your work in apologetics in particular and I have grown in confidence in my Christian witness.

My question relates to numbers and mathematics as a whole. On the Defenders podcast you state that as God is the only self-existent, necessary being, numbers and mathematical objects, whilst being useful, don’t actually exist as these too would exist necessarily and independently of God. If this is the case, how can it be that mathematics is so easily applied to the natural world? Surely if mathematics only existed in our minds, we would expect to see no correlation between it and how the physical world actually is?

Excerpt from the answer:

As philosopher of mathematics Mary Leng points out, for the non-theistic realist, the fact that physical reality behaves in line with the dictates of acausal mathematical entities existing beyond space and time is “a happy coincidence” (Mathematics and Reality [Oxford: Oxford University Press, 2010], p. 239). Think about it: If, per impossibile, all the abstract objects in the mathematical realm were to disappear overnight, there would be no effect on the physical world. This is simply to reiterate that abstract objects are causally inert. The idea that realism somehow accounts for the applicability of mathematics “is actually very counterintuitive,” muses Mark Balaguer, a philosopher of mathematics. “The idea here is that in order to believe that the physical world has the nature that empirical science assigns to it, I have to believe that there are causally inert mathematical objects, existing outside of spacetime,” an idea which is inherently implausible (Platonism and Anti-Platonism in Mathematics [New York: Oxford University Press, 1998], p. 136).

By contrast, the theistic realist can argue that God has fashioned the world on the structure of the mathematical objects. This is essentially what Plato believed. The world has mathematical structure as a result.

This argument was also made by mechanical engineering professor Walter Bradley in a lecture he gave on scientific evidence for an intelligent designer. You can read an essay that covers some of the material in that lecture at Leadership University.

Excerpt:

The physical universe is surprising in the simple mathematical form it assumes. All the basic laws of physics and fundamental relationships can be described on one side of one sheet of paper because they are so few in number and so simple in form (see table 1.1).

[…]It has been widely recognized for some time that nature assumes a form that is elegantly described by a relatively small number of simple, mathematical relationships, as previously noted in table 1.1. None of the various proposals presented later in this chapter to explain the complexity of the universe address this issue. Albert Einstein in a letter to a friend expressed his amazement that the universe takes such a form (Einstein 1956), saying:

You find it strange that I consider the comprehensibility of the world to the degree that we may speak of such comprehensibility as a miracle or an eternal mystery. Well, a priori one should expect a chaotic world which cannot be in any way grasped through thought. . . . The kind of order created, for example, by Newton’s theory of gravity is of quite a different kind. Even if the axioms of the theory are posited by a human being, the success of such an enterprise presupposes an order in the objective world of a high degree which one has no a priori right to expect. That is the “miracle” which grows increasingly persuasive with the increasing development of knowledge.

Alexander Polykov (1986), one of the top physicists in Russia, commenting on the mathematical character of the universe, said: “We know that nature is described by the best of all possible mathematics because God created it.” Paul Davies, an astrophysicist from England, says, “The equations of physics have in them incredible simplicity, elegance and beauty. That in itself is sufficient to prove to me that there must be a God who is responsible for these laws and responsible for the universe” (Davies 1984). Successful development of a unified field theory in the future would only add to this remarkable situation, further reducing the number of equations required to describe nature, indicating even further unity and integration in the natural phenomena than have been observed to date.

The whole paper that started this off is called “The Unreasonable Effectiveness of Mathematics”, and it is a must read for advanced Christian apologists. You can read the whole thing here.

UPDATE: Mysterious Tom posted this quote from David Berlinski on Facebook:

Why should a limited and finite organ such as the human brain have the power to see into the heart of matter and mathematics? These are subjects that have nothing to do with the Darwinian business of scrabbling up the greasy pole of life. It is as if the liver, in addition to producing bile, were to demonstrate an unexpected ability to play the violin.

That’s from David Berlinski’s “The Devil’s Delusion: Atheism and Its Scientific Pretensions”, (Basic Books, 2009, p. 16-17). Dr. Berlinksi is not a Christian – he is an agnostic.
