Sad cases among the modern physicists!

Next week at church I am going to review The Screwtape Letters by C.S. Lewis (1941). It is a highly amusing series of letters from Satan to his nephew, a devil in training. While re-reading it I came across this nice passage at the end of the first letter:
Above all, do not attempt to use science (I mean, the real sciences) as a defence against Christianity. They will positively encourage him to think about realities he can't touch and see. There have been sad cases among the modern physicists. If he must dabble in science, keep him on economics and sociology; don't let him get away from that invaluable "real life". But the best of all is to let him read no science but to give him a grand general idea that he knows it all and that everything he happens to have picked up in casual talk and reading is "the results of modern investigation".

Schrodinger's cat and all that!


Quantum physics is fertile ground for strange ideas, especially at the interface of science and theology. Ben Myers and I wrote a paper, published last year in the journal, Science and Christian Belief, that sought to explore parallels and differences between the epistemological issues associated with quantum physics and Karl Barth's theology. Perhaps, a more accessible summary is this talk I gave in Melbourne at an ISCAST conference.

J.S. Bach: soli deo gloria

One of the things that inspired the name of this blog was reading a beautiful series of articles about Johan Sebastian Bach in Christian History & Biography magazine. In one article, Calvin R. Stapert writes that Bach was

"arguably the greatest composer in the history of Western music and a man whose staunch Lutheran faith informed his life, his career, and his view of music. He believed that music was a "refreshment of spirit," as some of the title pages of his works stated. He believed that music was a powerful tool for the proclamation of the gospel, as his cantatas, Passions, organ chorales, and other compositions clearly show. And ultimately, he believed that music brought glory to God, as the initials SDG (Soli Deo Gloria, "To God alone be glory") at the end of most of his scores bear witness."

The aim and final end of all music should be none other than the glory of God and the refreshment of the soul. —J.S. Bach

The irreducible character of revelation

Revelation provides an example of a theological concept (and reality) that is not simply reducible to history, scripture, culture, religion, or sociology. God cannot be described and understood in purely human terms.

Barth states, “Revelation in the Bible means the self-unveiling, imparted to men, of the God who by nature cannot be unveiled to men.” He then expounds [Church Dogmatics I/1, pp. 315, 320, 324] this statement from three points of view, with a particular emphasis on the significance of the name of God, YHWH and of Jesus. God is Himself both in concealment and “in manifestation, i.e., in the form of something He Himself is not.” Anthropomorphic concepts such as:


“His arm, His right hand….. are not just [all too human] descriptions and representations of the reality of Yahweh; they are themselves the reality of Yahweh…. He has objectivity for those to whom He is manifest. Religious science usually defines concepts used in this way as hypostases, i.e., realities of the one God which are both distinguishable and yet also indistinguishable from Him.”


“this revelation of the name (Exodus 3:13ff.) is in fact, in content, the refusal to give a name, for “I am that I am” can hardly mean more than that “I am He whose true name no one can utter.” …But under this name, God does reveal himself to His people, i.e., He begins, as Exodus 3 instructively shows, to have dealings with Israel through the announcing by Moses of its deliverance out of Egypt.”


“the picture which the New Testament itself sets before us is that of the self-disclosure of this Father in which He is not the Father but the Son, the historical figure of this Man on His way from Bethlehem to Golgotha, the ‘name’ of Jesus. Again, the concreteness and actuality of the self-unveiling of God for man, and the enigma of the self-distinction in God Himself which makes this self-unveiling possible, has not just increased quantitatively here in comparison with the Old Testament.”


Hence, Revelation cannot be reduced to a historical event. In Revelation we find at the same time the greatest identification and the greatest difference between the person of God and the event of revelation.

What is "rational" public discourse?

Last week the Los Angeles Times ran a provocative opinion piece by Charlotte Allen,
Atheists: No God, no reason, just whining,
with the subtitle, "Superstar atheists are motivated by anger -- and boohoo victimhood". The article is worth reading. It concludes:
What atheists don't seem to realize is that even for believers, faith is never easy in this world of injustice, pain and delusion. Even for believers, God exists just beyond the scrim of the senses. So, atheists, how about losing the tired sarcasm and boring self-pity and engaging believers seriously?
The article got some very strong negative reactions from atheists. Some claimed the LA Times should not have printed it, as it was so filled with "hate". The response from P.Z. Myers (who Allen singled out in her article) is interesting. It is so filled with sarcasm, caricatures, and simplistic generalisations, that to me it only supports Allen's point.

So what do I consider are some hallmarks of rational discussion and argument?
  • Absence of anger, sarcasm, abuse, ridicule,...
  • Respect for others and their points of view, even when we strongly disagree
  • A desire to understand preceding attempting to be understood
  • Ackowledgement of subtleties of interpretation and evidence.
  • Thoughtful engagement with scholarly work, especially primary sources
"Be quick to listen, slow to speak, and slow to anger"

Does theology have implications for specific laws of physics?

Vern Poythress is a Professor of New Testament Interpretation at Westminister Theological Seminary in Philadelphia. He also has a Ph.D in Mathematics. He is author of the book, Redeeming Science: A God Centred Approach. The Seminary has sponsored a new web site The Truth about Angels and Demons, featuring material written by Poythress. It is very flash and worth a look.
But, one thing I had reservations about was a statement concerning antimatter:
The Word of God, the second Person of the Trinity, expresses the rationality and wisdom of God. The world that God made has deep harmonies because it was made by him and expresses him. In the Word, the wisdom of God, physical order (the positron) and mathematics hold together in harmony. Antimatter exists because it reflects within nature the harmony of God's mind, and the harmony between the persons of the Trinity.


This reminded me of some of the material in Alister McGrath's The Foundations of the Dialogue between Science and Religion (1998), of which I wrote a critical but appreciative review.
Chapter 2 contains a section (pp. 69-73) which discusses the fact that symmetry plays a major role in quantum theory. This might be of some theological interest because Aquinas argued that observed symmetries reflect the perfection of God. McGrath suggests that this interest has been offered a ``new lease of life'' because of the recent current interest in supersymmetry in theoretical physics. Later in the book (p. 181), in the context of the use of analogies in theology McGrath states:
It is important to pause here, and note the importance of the way in which the growth of ``supersymmetry'' theories have posited a fundamental relationship between various aspects of modern physics. The doctrine of creation, puts such relationships on a secure intellectual footing, suggesting that a correlation exists within the created order prior to its being discerned through human investigation.
Some of my concerns about this discussion of supersymmetry and this last point, in particular are, in order of increasing importance.

i. It is not at all clear that superstring theories will ever be tested experimentally because they would require particle accelerators bigger than the size of the earth. Hence, we may never know whether superstring theories really describe the created order rather than being just beautiful mathematical constructions.

ii. If supersymmetry really is an underlying symmetry of the physical laws of nature, the universe itself would still have only exhibited perfect supersymmetry (equal numbers of photons and photinos) during some incredibly short time, like the first 10 to the power -41 seconds, after the beginning of the universe. However, in the world in which we now live the supersymmetry is ``broken'', i.e., that is far from perfect. There are an ``astronomical'' number of photons in the universe but so far we have not found a single photino. Won't such imperfection present problems to Aquinas' argument?

iii. A statement by a theologian that theories based on symmetry are on a ``sound intellectual footing'' because of the doctrine of creation can be easily mis-interpreted as an endorsement of a specific scientific theory and is problematic. Wasn't that the source of Galileo's problems?

Angels and Demons: "fact" or science fiction? II

My previous post on Angel and Demons generated some traffic. I see that it is currently the most popular movie in Australia at the box office. I am curious whether the movie contains the following interaction in the novel, between the hero Robert Langdon, a Harvard Professor and expert in symbology, and Maximillian Kohler, a physicist and CERN director:
`Since the beginning of history,' Langdon explained, 'a deep rift has existed between science and religion. Outspoken scientists like Copernicus-'

`Were murdered,' Kohler interjected. `Murdered by the church for revealing scientific truths. Religion has always persecuted science.'
It appears that since the original edition, Copernicus has been replaced with Giordano Bruno, at least in my 2001 Corgi paperback edition. Why the change?

How did Copernicus die? He died following a stroke.
How were his theories received by the Roman Catholic church? What did Copernicus believe about the Bible? Wikipedia has detailed and well-referenced entries on Copernicus and Bruno. Here are extracts from the Copernicus entry:

On 1 November 1536, Archbishop of Capua Nicholas Schönberg wrote a letter to Copernicus from Rome:

Some years ago word reached me concerning your proficiency, of which everybody constantly spoke. At that time I began to have a very high regard for you... For I had learned that you had not merely mastered the discoveries of the ancient astronomers uncommonly well but had also formulated a new cosmology. In it you maintain that the earth moves; that the sun occupies the lowest, and thus the central, place in the universe... Therefore with the utmost earnestness I entreat you, most learned sir, unless I inconvenience you, to communicate this discovery of yours to scholars, and at the earliest possible moment to send me your writings on the sphere of the universe together with the tables and whatever else you have that is relevant to this subject ...[17]

By then Copernicus' work was nearing its definitive form, and rumors about his theory had reached educated people all over Europe. Despite urgings from many quarters, Copernicus delayed with the publication of his book, perhaps from fear of criticism — a fear delicately expressed in the subsequent Dedication of his masterpiece to Pope Paul III. Scholars disagree on whether Copernicus' concern was limited to physical and philosophical objections from other natural philosophers, or whether he was also concerned about religious objections from theologians.[18]

At original publication, Copernicus' epoch-making book caused only mild controversy, and provoked no fierce sermons about contradicting Holy Scripture. It was only three years later, in 1546, that a Dominican, Giovanni Maria Tolosani, denounced the theory in an appendix to a work defending the absolute truth of Scripture.[32] He also noted that the Master of the Sacred Palace (i.e., the Catholic Church's chief censor), Bartolomeo Spina, a friend and fellow Dominican, had planned to condemn De revolutionibus but had been prevented from doing so by his illness and death.[33]

Arthur Koestler, in his popular book The Sleepwalkers, asserted that Copernicus' book had not been widely read on its first publication.[34] This claim was trenchantly criticised by Edward Rosen,[35] and has been decisively disproved by Owen Gingerich, who examined every surviving copy of the first two editions and found copious marginal notes by their owners throughout many of them. Gingerich published his conclusions in 2004 in The Book Nobody Read.[36]

It has been much debated why it was not until six decades after Spina and Tolosani's attacks on Copernicus's work that the Catholic Church took any official action against it. Proposed reasons have included the personality of Galileo Galilei and the availability of evidence such as telescope observations.

In March 1616, in connection with the Galileo affair, the Roman Catholic Church's Congregation of the Index issued a decree suspending De revolutionibus until it could be "corrected," on the grounds that the supposedly Pythagorean doctrine[37] that the Earth moves and the Sun doesn't was "false and altogether opposed to Holy Scripture."[38]
So, not only was Copernicus not murdered by the church, but it seems some church leaders were actually very receptive to his ideas. And it was only sixty years after his death that the church opposed his work.

On the other hand, Bruno was definitely condemned to death by the church. But, was it for his scientific views? The wikipedia entry on Bruno expands on the subtleties involved:

Some authors have characterized Bruno as a "martyr of science," suggesting parallels with the Galileo affair. They assert that, even though Bruno's theological beliefs were an important factor in his heresy trial, his Copernicanism and cosmological beliefs also played a significant role for the outcome. Others oppose such views, and claim this alleged connection to be exaggerated, or outright false.

According to the Stanford Encyclopedia of Philosophy, "in 1600 there was no official Catholic position on the Copernican system, and it was certainly not a heresy. When [...] Bruno [...] was burned at the stake as a heretic, it had nothing to do with his writings in support of Copernican cosmology."[16]

Similarly, the Catholic Encyclopedia (1908) asserts that "Bruno was not condemned for his defence of the Copernican system of astronomy, nor for his doctrine of the plurality of inhabited worlds, but for his theological errors, among which were the following: that Christ was not God but merely an unusually skilful magician, that the Holy Ghost is the soul of the world, that the Devil will be saved, etc."[17]

However, the webpage of the Vatican Secret Archives discussing the document containing a summary of legal proceedings against him in Rome, suggests a different perspective:

"In the same rooms where Giordano Bruno was questioned, for the same important reasons of the relationship between science and faith, at the dawning of the new astronomy and at the decline of Aristotle’s philosophy, sixteen years later, Cardinal Bellarmino, who then contested Bruno’s heretical theses, summoned Galileo Galilei, who also faced a famous inquisitorial trial, which, luckily for him, ended with a simple abjuration."[18]

I took a fascinating visit to the relevant Vatican Secret Archives webpage and also found the following statement of Bruno:
Firstly, I say that the theories on the movement of the earth and on the immobility of the firmament or sky are by me produced on a reasoned and sure basis, which doesn’t undermine the authority of the Holy Sciptures […]. With regard to the sun, I say that it doesn’t rise or set, nor do we see it rise or set, because, if the earth rotates on his axis, what do we mean by rising and setting[…])
Congratulations, if you read this far! This post took longer than I originally thought because it turned out so much more complicated [and richer] than I anticipated. But, isn't that the way science, history, theology, and life often are!

Dan Brown and Richard Dawkins do not wish to engage with subtleties and shades of gray. For them, it is simple:
Since the beginning of history ...... a deep rift has existed between science and religion. Outspoken scientists .....Were murdered .... by the church for revealing scientific truths. Religion has always persecuted science.
