A Fine-Tuned Universe: The Quest for God in Science and Theology
Are there viable pathways from nature to God? Natural theology is making a comeback, stimulated as much by scientific advance as by theological and philosophical reflection. There is a growing realization that the sciences raise questions that transcend their capacity to answer them—above all, the question of the existence of God. So how can Christian theology relate to these new developments?
In this landmark work, based on his 2009 Gifford lectures, Alister McGrath examines the apparent “fine-tuning” of the universe and its significance for natural theology. Exploring a wide range of physical and biological phenomena and drawing on the latest research in biochemistry and evolutionary biology, McGrath outlines our new understanding of the natural world and discusses its implications for traditional debates about the existence of God.
The celebrated Gifford Lectures have long been recognized as making landmark contributions to the discussion of natural theology. A Fine-Tuned Universe will contribute significantly to that discussion by developing a rich Trinitarian approach to natural theology that allows deep engagement with the intellectual and moral complexities of the natural world. It will be essential reading to those looking for a rigorous engagement between science and the Christian faith.

While one might guess from the title that this book is about the anthropic principle, it's actually about an alternative way to look at natural theology. In a 2005 book ("Dawkins' God: Genes, Memes, and the Meaning of Life") McGrath concluded that William Paley's "Natural Theology" was an experiment that had failed as an approach to Christian apologetics. In his 2008 book "The Open Secret: A New Vision for Natural Theology," McGrath presented the basic elements of a new vision for natural theology. This 2009 book describes his alternative approach to natural theology, which McGrath labels a Trinitarian approach. It involves applying counterfactual thinking to natural theology, which results in an "explanatory unification" that "resonates strongly with our observation and experience of the world" and "the capacity to confer meaning."
The usual approach to natural theology can disclose a god, but not the God of Christianity. "Deism holds that God created the world; theism holds that God created the world and continues to direct it through divine providence; Trinitarianism holds that God created the world, continues to direct it through divine providence, and guides the interpreters of both the books of nature and Scripture through the illumination of the Holy Spirit. The Trinitarian approach to natural theology does not prove the existence of God, but "offers a high degree of consonance with what is actually observed."
McGrath begins with a brief history of the place of natural theology, from "proving the existence of God" to using it to argue "that Christianity makes better sense of the empirical evidence than any of its alternatives or rivals by interpreting nature on the basis of Christian beliefs." Quoting McGrath: "One of the most fundamental concerns was the intellectual integrity of Paley's core argument. How could one speak of observing "design" in nature? One observes nature, but one infers design in nature. Design is not an empirical datum, but reflects the interpretation of what is observed."
Chapter 8 is the best discussion of Augustine's views of creation that I have yet seen anywhere. McGrath demonstrates that Augustine believed that God brought everything into being at a specific moment, with embedded causalities that emerged or evolved at a later stage, which we now refer to as the "big bang" and biological evolution. McGrath supports his views with numerous references to Augustine's "De Genesi ad litteram (The Literal Interpretation of Genesis)."
Chapters 9-14 present applications of counterfactual thinking to anthropic phenomena, origins of life, the curious chemistry of water, chemical catalysis and the constraints of evolution, and the mechanism and directionality of evolution. These chapters are also very good summaries of the current research in these areas. Alister McGrath has an excellent grasp of what's currently going on in a wide range of sciences and presents it in a readable style.
The extensive footnotes are thoughtfully placed at the bottom of the page on which they occur, and there is a 36-page bibliography and a 4-page index. This is a well-referenced book. I recommend it to anyone with an interest in natural theology.

MCGRATH LINKS FINE-TUNING TO CHRISTIAN NATURAL THEOLOGY
Author Alister McGrath wrote in the Introduction to this 2009 book, “The topic of this book is the quest for God in the natural sciences and Christian theology, traditionally known as ‘natural theology.’ … Natural theology languished in the intellectual doldrums for much of the twentieth century… Yet there is every sign that natural theology is now emerging from its period of eclipse.” (Pg. ix) He continues, “This book aims to take this discussion further, both in terms of developing a natural theology which is adapted to intellectual engagement with the natural sciences, and contributing toward the scientific, philosophical, and theological discussion of the wider meaning of anthropic phenomena. I do not argue that fine-tuning represents a proof of the Christian belief in God; I nevertheless insist that it is consonant with the Christian vision of God, which is believed to be true on other grounds… This book sets out to establish and explore the intellectual virtues of a Trinitarian natural theology, chiefly by considering the significance of the observation of fine-tuning or anthropic phenomena in any coherent account of reality.” (Pg. xii-xiv)
He outlines, “we might BEGIN by seeing natural theology as disclosing simply a creator God… in the light of the Christian revelation, we realize that this provisional judgment is ultimately unsustainable and requires reworking and reconceptualization…. We end with a Trinitarian vision of God… The God, who IS Trinity, is not originally PERCEIVED AS Trinitarian. This approach… allow nature to be seen as a signpost to the transcendent, without entailing that this God is exhaustively determined, defined, and characterized by being known in this way… I have no intention of arguing that one may ‘probe’ any aspect of the Christian faith by the perspicuous observation and interpretation of the natural world. Rather, I shall argue that such observation gives rise to the perception that there is a fundamental consonance between Christian theory and empirical observation.” (Pg. 33-34)
He points out, “Examples of … the astrophysical fine-tuning of fundamental cosmological constants include the following: 1. If the strong coupling constant were slightly smaller, hydrogen would be the only element in the universe… 2. If the weak fine constant were slightly smaller, no hydrogen would have formed during the early history of the universe. Consequently, no stars would have been formed… 3. If the electromagnetic fine-structure constant were slightly larger, the stars would not be hot enough to warm planets to a temperature sufficient to maintain life… 4. If the gravitational fire-structure were slightly smaller, stars and planets would not have been able to form…” (Pg. 92-93)
He notes, “The values of certain fundamental cosmological constants and the character of certain initial conditions of the universe appear to have played a decisive role in bringing about the emergence of a particular kind of universe, within which life is capable of developing. (Pg. 116) He adds, “God, then, unquestionably represents a plausible explanation of anthropic phenomena. But is this the BEST explanation?... The fundamental constants in question had to have SOME value---so why not these ones?... At one level, it is impossible to refute this argument. Yet it is clearly inadequate to account for the actualization of a highly improbable scenario: the emergence of a universe adapted for life.” (Pg. 121)
He observes, “Darwin’s theory certainly indicates that it is no longer NECESSARY to appeal to a creator God to account for the apparent design of living things… Yet while this demonstrates that a theistic account of biological design is not entailed, it does not entail the much stronger and rather more significant claim that either theism itself, or a theistic account of biological design, is FALSE. As a result, theists are free to agree that natural processes are adequate to explain biological design, but they are also free to insist that theism provides another equally rational and plausible explanations which may ultimately prove to be the BEST explanation.” (Pg. 196)
He concludes, “It is hoped that the explorations set out in this book will stimulate further interest in the future of natural theology, the explanatory dimensions of Trinitarianism, and the significance of anthropic phenomena. I have sought to avoid the excesses of those theist enthusiasts who fix upon fine-tuning as certain evidence for the existence of God on the one hand, and their atheist counterparts on the other, who often seek refuge in the notion of a multiverse to avoid the theistic implications of the phenomena we have been surveying.” (Pg. 220)
This book will be of great interest to those studying cosmological fine-tuning, the Anthropic Principle, as well as the Philosophy of Religion.

Although slightly dated, this book by McGrath contributed to the case for a natural theology in that the Book of Nature and the Book of Life (the Bible) inform each other.

Thoughtful and admirable, open-minded. Likely best heard than read. Yet explosively including the divine in everything.

February 21, 2024McGrath attempts to "rescue" and redefine natural theology in this write-up of his Gifford lectures.
McGrath's new natural theology focuses not on deductive proofs from nature, but on the resonance between Christian theism and our current knowledge of the natural world. Rather than arguing from principles in nature, McGrath commends a Trinitarian vision of reality as the most fitting lens to view the natural world with. He draws on Augustine's doctrine of creation, showing how it encourages us to view God's creative act as containing emergent properties, as well as simply actual ones. Of course, this resonates nicely with our current notions of an evolving cosmos and evolving creatures.
This is all contained in Part I; Part II takes a tour through the natural history of our planet and our universe. As McGrath explicates various scientific theories and details, he comments on their potential to resonate with Christian theism. Mostly, this is evident in how "finely-tuned" a vast amount of different constants and factors are to allow life as it is today.
What I would have liked to have seen more of in this section is an account of how these scientific details resonated in particular with a Trinitarian vision of reality. It seems to me that fine-tuning could resonate with a variety of worldviews and there's nothing Christianity can do to commend itself more highly than others. However, it's possible that McGrath's previous work on natural theology, "The Open Secret," contains more on this particular point. I look forward to reading it.
Regardless of my critique, I found this book a great starting point for Christian approaches to science. I'm drawing on it heavily for my upcoming seminar on Christianity and science, which I guess indicates something very good about the quality and helpfulness of this book.
Highly recommended

I've been a big fan of McGrath for over 2 decades now, and once again I enjoyed reading his book. It is an interesting endeavour to show that a Trinitarian Natural Theology works well with Modern Scientific Theories, and in particular with modern Biological (ie Evolutionary) theories.
Let me say, that I lean more towards an Old Earth Creationism model. I have no problem with excepting a Big Bang Cosmology nor with a 14 billion year old Universe. I also have no problem with Natural Selection and what may be term "small scale" evolution - it's the macro evolution I struggle with. McGrath doesn't really argue for a Theistic Evolutionary approach, rather I believe he is arguing that his model would work with one. However it does appear to be the only model he discusses besides Paley's very static model.
Please also note, that my Science background is more the Maths / Physics side of things - so much of the Biochemistry and Biology discusses is way above my head - though I still enjoyed reading it and did learn from it.
I also think the McGrath has succeeded in arguing for a Theistic Natural Theology rather than a Trinitarian one. I wasn't really convinced that his model only works with the Christian Triune God - rather would work probably just as well with a Mormon Worldview or even a Muslim Worldview. Especially at the end of the book, I think he needed to tie things together better and argue the Trinitarian side of things.
Anyway I enjoyed the book and it gave me much to think about :)

I will be writing up notes and thoughts on this work and posting them on my book blog sometime this summer. Until then, McGrath gives me much to consider and reconsider regarding the relationship between theology and science. It is a worthy read and I thank Jim Van Eerden for gifting me with these thoughts...
