Well done, Moderator

The Moderator of the General Assembly of the Church of Scotland has done a good job for us all today.

Responding to Stephen Hawkin's latest dismissal of God, John, our Moderator this year, has reaffirmed a Christian profession of God as Creator. You can read the Scotsman's report here. I read it in the Herald this morning, but their web site is so bad you can never find anything you want on it!

I notice the Scotsman have included some quotes from Scripture to end their piece, at least on line. There's one they missed out. The biblical definition of a fool is given in Ps 14:1
The fool says in his heart there is no God.

You can have as many degrees or professorships as you can bear, but if you deny the existence of God, you are a fool.

God Isn't Deluded, Even If Dawkins Is!

As we anticipate the publication of another book by Richard Dawkins, described on the cover rather grandly as ‘the most formidable intellect in public discourse’, I share here a section on the Delusion under which Dawkins labours from William Lane Craig. I found this on the EA site, here.

I feel increasing sure that God really isn’t impressed by Dawkins and the so called new atheists.

Dawkin’s Delusion

Richard Dawkins has emerged as the enfant terrible of the movement known as the New Atheism. His best-selling book The God Delusion has become the literary centerpiece of that movement. In it Dawkins aims to show that belief in God is a delusion, that is to say, "a false belief or impression," or worse, "a persistent false belief held in the face of strong contradictory evidence." On pages 157-58 of his book, Dawkins summarizes what he calls "the central argument of my book." Note it well. If this argument fails, then Dawkins's book is hollow at its core. And, in fact, the argument is embarrassingly weak.

It goes as follows:

1. One of the greatest challenges to the human intellect has been to explain how the complex, improbable appearance of design in the universe arises.
2. The natural temptation is to attribute the appearance of design to actual design itself.
3. The temptation is a false one because the designer hypothesis immediately raises the larger problem of who designed the designer.
4. The most ingenious and powerful explanation is Darwinian evolution by natural selection.
5. We don't have an equivalent explanation for physics.
6. We should not give up the hope of a better explanation arising in physics, something as powerful as Darwinism is for biology.
7. Therefore, God almost certainly does not exist.

This argument is jarring because the atheistic conclusion that "therefore, God almost certainly does not exist" seems to come suddenly out of left field. You don't need to be a philosopher to realize that that conclusion doesn't follow from the six previous statements. Indeed, if we take these six statements as premises of an argument intended logically to imply the conclusion "therefore, God almost certainly does not exist," then the argument is patently invalid. No logical rules of inference would permit you to draw this conclusion from the six premises.

A more charitable interpretation would be to take these six statements not as premises but as summary statements of six steps in Dawkins's cumulative argument for his conclusion that God does not exist. But even on this charitable construal, the conclusion "therefore, God almost certainly does not exist" simply doesn't follow from these six steps, even if we concede that each of them is true and justified. The only delusion demonstrated here is Dawkins's conviction that this is "a very serious argument against God's existence."

So what does follow from the six steps of Dawkins's argument? At most all that follows is that we should not infer God's existence on the basis of the appearance of design in the universe. But that conclusion is compatible with God's existence and even with our justifiably believing in God's existence. Maybe we should believe in God on the basis of the cosmological argument or the ontological argument or the moral argument. Maybe our belief in God isn't based on arguments at all but is grounded in religious experience or in divine revelation.

Maybe God wants us to believe in Him simply by faith. The point is that rejecting design arguments for God's existence does nothing to prove that God does not exist or even that belief in God is unjustified. Indeed, many Christian theologians have rejected arguments for the existence of God without thereby committing themselves to atheism. Dawkins's argument for atheism is a failure even if we concede, for the sake of argument, all its steps. But, in fact, several of these steps are plausibly false in any case. Take step 3, for example. Dawkins's claim here is that one is not justified in inferring design as the best explanation of the complex order of the universe because then a new problem arises: Who designed the designer?

This objection is flawed on at least two counts. First, in order to recognize an explanation as the best, one needn't have an explanation of the explanation. This is an elementary point concerning inference to the best explanation as practiced in the philosophy of science. If archaeologists digging in the earth were to discover things looking like arrowheads and hatchet heads and pottery shards, they would be justified in inferring that these artifacts are not the chance result of sedimentation and metamorphosis but products of some unknown group of people even though they had no explanation of who these people were or where they came from. Similarly, if astronauts were to come upon a pile of machinery on the back side of the moon, they would be justified in inferring that it was the product of intelligent, extraterrestrial agents even if they had no idea whatsoever who these extraterrestrial agents were or how they got there. In order to recognize an explanation as the best, one needn't be able to explain the explanation. In fact, so requiring would lead to an infinite regress of explanations so that nothing could ever be explained and science would be destroyed. In the case at hand, in order to recognize that intelligent design is the best explanation of the appearance of design in the universe, one needn't be able to explain the designer.

Second, Dawkins thinks that in the case of a divine designer of the universe, the designer is just as complex as the thing to be explained so that no explanatory advance is made. This objection raises all sorts of questions about the role played by simplicity in assessing competing explanations-for example, how simplicity is to be weighted in comparison with other criteria like explanatory power, explanatory scope, plausibility, and so forth. If a less simple hypothesis exceeds its rivals in explanatory scope and power, for example, then it may well be the preferred explanation despite the sacrifice in simplicity.

But leave those questions aside. Dawkins's fundamental mistake lies in his assumption that a divine designer is an entity comparable in complexity to the universe. As an unembodied mind, God is a remarkably simple entity. As a nonphysical entity, a mind is not composed of parts; and its salient properties-like self-consciousness, rationality, and volition-are essential to it. In contrast to the contingent and variegated universe with all its inexplicable physical quantities and constants (mentioned in the fifth step of Dawkins's argument), a divine mind is startlingly simple. Certainly such a mind may have complex ideas (it may be thinking, for example, of the infinitesimal calculus), but the mind itself is a remarkably simple entity. Dawkins has evidently confused a mind's ideas, which may indeed be complex, with a mind itself, which is an incredibly simple entity. Therefore, postulating a divine mind behind the universe most definitely does represent an advance in simplicity. Other steps in Dawkins's argument are also problematic; but I think enough has been said to show that his argument does nothing to undermine a design inference based on the universe's complexity, not to speak of its serving as a justification of atheism.

Several years ago my atheist colleague Quentin Smith unceremoniously crowned Stephen Hawking's argument against God in A Brief History of Time as "the worst atheistic argument in the history of Western thought."5 With the advent of !e God Delusion the time has come to relieve Hawking of this weighty crown and to recognize Richard Dawkins's accession to the throne.

William Lane Craig is research professor of Philosophy at Talbot School of Theology in La Mirada, California. His Ph.D. in Philosophy is from the University of Birmingham in the United Kingdom.

Facts or/and ideology

It is reported today, see The Herald, that President Obama has overturned a ban on stem cell research. I'm not posting about stem cell research, but about what the President has said in making this decision.

'In lifting the ban, the president stated yesterday that he would make scientific decisions "based on facts, not ideology" from now on.' Facts, not ideology. But later in this article the President is further quoted:
"As a person of faith, I believe we are called to care for each other and work to ease human suffering. I believe we have been given the capacity and will to pursue this research - and the humanity and conscience to do so responsibly."

To believe that we are called to care for each other is not a fact, it is a belief position, an ideology if you like. As humans we function as believing creatures, we act upon points, articles of faith. This is how we have been made. Even to deny that ideology, or faith, has any place in government decision making is a faith, or ideological position.

But more importantly, we cannot deny that many if not all of the decisions made by our governments involve moral choices. There is a choice to be made between moral values and scientific enquiry. This is why we should have our scientists governed by those with moral authority, or at least a moral responsibility to protect the vulnerable and weak.

President Obama has fallen into the false position of claiming to be a person of faith, yet acting independently of his faith. I for one don't want the leaders of our nations to divorce their faith from their decision making.
