Christian Platonism and Science

Recently the theology reading group we discussed A Christian Theology of Science: Reimagining a Theological Vision of Natural Knowledge by Paul Tyson. 

Paul is a former member of our group and so were happy he could join us to discuss his book. Here is one summary.

We have come to separate natural knowledge (science) from faith and moral beliefs (religion), leading to serious difficulties in integrating knowledge and meaning, facts and values, and immanence and transcendence.

At the root of these dissonances is the difficult relationship between a naturalistic philosophy that purports to be a scientific realism and the things that make us human: transcendence, faith, meaning, and purpose. This is the result of science displacing Christian theology as Western modernity's first truth discourse. However, Christian theology contains deep resources in its approach to knowledge and reality that have not been brought to the science and religion conversation since the late nineteenth century.

I have a great interest in the subject of this book and it stimulated and challenged my thinking. 

Tyson builds on two important ideas from the historian Peter Harrison. In his book, Territories of Science and Religion, Harrison makes the case that "science" and "religion" are ill-defined entities and their definition and "territories" [the domain of their relevance and authority] have shifted over time. Second, in a 2006 article, Harrison, observes that in the late 19th century there was a "remarkable reversal" "from Christian theology interpreting the true meaning and validity of natural philosophy to science interpreting the true meaning and validity of Christian theology" (page 31).

In other words, "This is a profound shift from faith-based theocentric ontological foundationalism (TOF) to egocentric epistemological foundationalism (EEF)." (p. 32). 

Thankfully, there is a ten-page glossary at the back of the book so the reader can keep refreshing their memory of how the author defines different terms. This is important as terms such as truth, theory, quality, meaning, wisdom, knowledge, and understanding are used in the sense that Plato used them, not how a modern scientist or citizen might use such terms. For example, theory (theoria) is "A vision of meaning. An inescapably imaginative and interpretive act of the meaning-discerning mind" (p.120).

I appreciated the book for giving a gentle introduction to a range of philosophical concepts, particularly metaphysics and transcendence.

The heart of the book is chapter 7, which includes several helpful diagrams, such as the one below, based on Plato's metaphysics.

This is based on four distinct categories of awareness considered by Plato. Tyson translates these into wisdom, mathematics, belief, and perception.

The central claim of the book is that modern science as a "first truth cultural discourse" has made the line between rationalism and wisdom uncrossable. In other words, modern physics has reduced metaphysics to the unreal, the realm of speculation and fantasy. We cannot know the true essence of reality, the ground of being. We can only know existence. Tyson has a very different vision. He claims that the separation of metaphysics and physics is intellectually incoherent. He cannot accept the position of some Christian scientists, such as myself, that the methodological naturalism of science is not necessarily in tension with Christian theology. He wants to imagine that Christian theology can provide a vision of natural knowledge.

Today we are a long way from Plato who considered metaphysics as the basis of physics. That is, one starts with qualities such as the character of God and from that reason towards what one thinks the world is like. This led to Aristotelian physics, which was discredited by Copernicus, Galileo, and Newton. This is why scientists, Christians and non-Christians, are nervous about elevating Christian theology [a specific metaphysics] back to its pre-modern status as "the first truth discourse". It has a bad track record.

On the other hand, some atheist scientists claim physics determines metaphysics. In different words, the content of physical theories tells us what the world is really like. Science determines questions of meaning, purpose, values, and morality.

Update. (March 2024). Peter Harrison has written a helpful review of the book.

Why read Old Testament books?

 A wonderful feature of The Message by Eugene Peterson is that the edition that I have has an introduction to each book of the Bible from the perspective of Peterson. At church we just started a sermon series on 2 Kings and so I just reread the introduction for Kings 1 and 2. Here it is.

Sovereignty, God's sovereignty, is one of the most difficult things for people of faith to live out in everyday routines. But we have no choice: God is Sovereign. God rules. Not only in our personal affairs, but in the cosmos. Not only in our times and places of worship, but in office buildings, political affairs, factories, universities, hospitals—yes, even behind the scenes in saloons and rock concerts. It's a wild and extravagant notion, to be sure. But nothing in our Scriptures is attested to more frequently or emphatically.

Yet not much in our daily experience confirms it. Impersonal forces and arrogant egos compete for the last word in power. Most of us are knocked around much of the time by forces and wills that give no hint of God. Still, generation after generation, men and women of sound mind continue to give sober witness to God's sovereign rule. One of the enduring titles given to Jesus is “King.”

So how do we manage to live believingly and obediently in and under this revealed sovereignty in a world that is mostly either ignorant or defiant of it?

Worship shaped by an obedient reading of Scripture is basic. We submit to having our imaginations and behaviors conditioned by the reality of God rather than by what is handed out in school curricula and media reporting. In the course of this worshipful listening, the Books of Kings turn out to provide essential data on what we can expect as we live under God's sovereign rule.

The story of our ancestors, the Hebrew kings, began in the Books of Samuel. This story makes it clear that it was not God's idea that the Hebrews have a king, but since they insisted, he let them have their way. But God never abdicated his sovereignty to any of the Hebrew kings; the idea was that they would represent his sovereignty, not that he would delegate his sovereignty to them.

But it never worked very well. After five hundred years and something over forty kings, there was not much to show for it. Even the bright spots—David and Hezekiah and Josiah—were not very bright. Human beings, no matter how well intentioned or gifted, don't seem to be able to represent God's rule anywhere close to satisfactory. The Books of Kings, in that light, are a relentless exposition of failure—a relentless five-hundred-year documentation proving that the Hebrew demand of God to “have a king” was about the worst thing they could have asked for.

But through the centuries, readers of this text have commonly realized something else: In the midst of the incredible mess these kings are making of God's purposes, God continues to work his purposes and uses them in the work—doesn't discard them, doesn't detour around them; he uses them. They are part of his sovereign rule, whether they want to be or not, whether they know it or not. God's purposes are worked out in confrontation and revelation, in judgment and salvation, but they are worked out. God's rule is not imposed in the sense that he forces each man and woman into absolute conformity to justice and truth and righteousness. The rule is worked from within, much of the time invisible and unnoticed, but always patiently and resolutely there. The Books of Kings provide a premier witness to the sovereignty of God carried out among some of the most unlikely and uncooperative people who have ever lived.

The benefit of reading these books is enormous. To begin with, our understanding and experience of God's sovereignty develops counter to all power-based and piety-based assumptions regarding God's effective rule. We quit spinning our wheels on utopian projects and dreams. Following that, we begin to realize that if God's sovereignty is never canceled out by the so deeply sin-flawed leaders (“kings”) in both our culture and our church, we can quite cheerfully exult in God's sovereignty as it is being exercised (though often silently and hiddenly) in all the circumstantial details of the actual present.
