It will be immediately obvious to the reader of David Bentley Hart’s new book that the structure is quite different to most other titles on the philosophy of mind.  

Hart admits that in its original form it was in fact far longer than its substantial 500 plus pages, but, in a perhaps inspired move, it has undertaken a metamorphosis from the ponderous-tome genre of philosophical discourse to one much older: the dialogue. 

Instead of other such works which draw on an enormous and panoramic amount of literature presented in regular academic style with copious footnotes, Hart has opted for intelligibility in the mode of a dialogue between characters, historically most notably deployed by Plato. For this reason, it works well as an audiobook, as well as printed text. The downside to this format is that Hart has opted for a somewhat unfortunate weighting of three-on-one. Whilst this format makes the twist and turn of the at times obstruse argumentation more accessible, the impression can feel somewhat unbalanced. Hephaistos, one of those in dialogue, sometimes cuts a lonely and sympathetic figure, and his opponents sometimes are slightly too self-satisfied. This is not overwhelmingly so, but it is worth remembering that all voices are Hart’s.  

His choice of dialogicians is telling - four Greek divinities. Psyche (soul), the mortal woman made divine by love. Eros (love), the divine lover of Psyche, Hermes, Psychopomp (that is, the guide of souls in the afterlife). And the stolid Hephaistos, god of craft and manufacture, the main antagonist as the advocate of all things materialist and physicalist. Three characters signal Hart’s intent to guide the reader into a new realm beyond the mundane; the fourth is the mouthpiece of this mundanity. Together in a garden, prompted by a plucked rose, they discuss some the deepest questions of mind, matter, and life.  

The title, All Things Are Full of Gods, is a quotation attributed to the pre-Socratic philosopher Thales. Like Thales, Hart wants to argue that not only is the divine a reality but is in fact the ground of all things. The six days of dialogue cover the full gauntlet of metaphysical debate over the nature of reality.   

On day one, ‘Mind, Life, and Pictures of Reality’ the gods set up the groundwork of the reductionist materialist physicalism (RMP) perspective and the older pictures of classical philosophies. 

Day two, ‘Mind and Matter’, draws the battlelines between the qualitative difference between mind and matter. 

Day three, ‘Brain and Mind’, engages with arguments concerning how mind and matter relate. 

On day four, ‘Machine and Soul’, the place of mind in the body is deepened in the debates on computationalism and functionalism and a useful unpacking of the limitations of panpsychism, which is currently seeing a revival in philosophical circles. 

Day five, ‘Soul and Nature’, sees the dialogue broadened to nature itself, reconsidering the mechanical paradigm which presently dominates. 

Concluding, day six, ‘Nature and Supernature’, is where Hart delivers his final case, having thoroughly prepared the ground, arguing that mind characterises all of reality and that this is ultimately the only truly rational account of being.  

In an important ‘Coda: The Age of the Machine’ Hart addresses the problem of evil, something largely absent from the rest of the work. Hart has a good track record on this topic: The Doors of the Sea, written in light of the Boxing Day Tsunami, is essential reading for Christians and others who see the paradox between an all-loving, all-powerful God and the presence of suffering and evil. Readers will have to decide for themselves; it is not a topic on which one may enforce an opinion either way. The discussion concludes on the sixth day, “. . . and on the seventh day they rest.” (483) 

Whilst All Things is dialogic, it also appears to be something else: catechesis. Hart is a catechist. Theologian and philosopher also; linguist certainly; provocateur undoubtedly. But the intention of this book is to catechise the reader, to induct them into the mystery of mind and reality. This might be a somewhat dusty word to some, implying the rote learning of religious dogma. Others will be barely aware of such a word. In Christianity, catechesis is the process of instruction, usually conducted through question and answer.  

Hart is an Eastern Orthodox Christian, though in many ways an unorthodox one. His commitment to a form of perennialism, his belief that many of the major religious philosophies of the world (Vedic, Greek, Jewish, Christian, Islamic) share important and compatible insights into the nature of reality and God as the primordial ground of all things, is evident through the pages of All Things. This is unsurprising as he states that of all his writings All Things is the natural successor to The Experience of God: Being, Consciousness, Bliss (a deliberate allusion to the Vedic concepts of sit, chat, ananda) in which he sought to argue the rational coherence of a theism shared by a number of the great religions over and against the irrationality of modern physicalist materialism. It is worth reading and would certainly give the reader of All Things a primer for the extended discussion.  

But how is it exactly catechesis? Hart wants to wean the reader off the junk food of popular science with its tendency to not take questions about its philosophical basis very seriously, especially in how its epistemology, ‘what it knows’, produces its ontology, ‘what exists’. This deficiency, as Hart is keen to point out, means that often ontology secretly precedes epistemology. For instance, most scientist will take central place of mathematics within their discipline for granted, without acknowledging that mathematics is itself is groundless: it is epistemologically irreducible as it is not empirical, but is ontologically essential to the scientific method. Hart argues that it is in it’s very groundlessness and givenness to intelligibility, i.e. that the world can be understood at all, that means the world in fact shows itself to have rational mind-like structure, capable of being known. Many advocates for RMP will simply shrug and say that we’ve simply evolved to see structure which isn’t inherently there; Hart is here to pick a philosophical bone with them. His intention as catechist is that, even if one does not become a Christian at the end of this book, one can no longer remain in the comfortable and familiar philosophical milk of the dominant RMP paradigm but be stirred to hunger for the meat of reality. Although not an explicitly Christian book, there are certain hints. A number of Christian theologians recur, especially towards the end: Karl Rahner, Bernard Lonergan, Meister Eckhart. That the dialogue is set over six days “. . . and on the seventh day they rest” (483) ought not to be lost on the reader. 

His position in a nutshell is that all is mind or spirit (this linking of terms that are separate in English derives from their indistinction in the German Geist, used extensively in German Idealism, in which a lot of this debate has its origins in modernity). This is not a denial of matter (as in some forms of idealism), but that matter is a material manifestation or substrate of the principle of mind behind all reality: God. In many ways All Things is the extension of his previous book, The Experience of God: Being, Consciousness, Bliss, which he acknowledges in the ‘Introduction’. His position is argued in response to the currently most dominant intellectual paradigm, RMP: the idea that reality consists only of that which is matter or can be observed as a consistent mechanical attribute of matter (such as gravity).  

Hart’s argument rests on a number of fallacies in this paradigm; the most important of these and the one which recurs most frequently throughout the dialogue between the gods is the ‘pleonastic’ fallacy:  

No matter how many purely objective quantitative steps the supposedly mechanistic material order may have taken in the direction of mind, none of them seems as if it could have constituted that sudden qualitative transition from pure exteriority into an unprecedented inwardness.  

In short, quantitative accumulation cannot produce qualitative transformation. Mind is not another form of exterior reality, like the physical world; thought takes up no space and is of an entirely different, interior order. This is Hart’s principle complaint against both RMP and historical forms of dualism such as that of Descartes. The six ‘days’ of dialogue is essentially an account of the various arguments presented by the RMP paradigm to demonstrate that this fallacy is not in fact true. The most important of these concerns the trend in various sciences to speak of ‘emergence’: the appearing of qualities or realities such as mind which, whilst dependent upon a physical foundation for their existence, cannot be understood or explained by examination of their physical foundation; they cannot be reduced (explained) by the substrate. Hart draws the distinction between water’s property to extinguish fire, despite it being made up of the highly combustible elements hydrogen and oxygen, and the emergence of mind as a different order of reality from physical combination: 

Physical properties derived from other physical properties—no great problem there. So long as this is all that’s meant by “emergence,” then the concept is as inoffensive as it is obvious. But there’s a point at which vague talk of emergence is just another way of talking about something that you might otherwise justly call magic.

This is because water’s watery-ness is also a physical phenomenon, the product of the combination of these particular elements in this particular configuration. But this is still and exterior reality; mind on the other hand is not a property like the watery-ness of water because mind is an interior phenomenon, one which is entirely inaccessible except for the mind who is the mind in first-person perspective. To then argue that pure exterior accumulation quantitative of reality can produce this interiority is, to Hart, not only nonsensical but irrational. Part of his argument thus also turns upon the principle of Occam’s Razor: “if you have two competing ideas to explain the same phenomenon, you should prefer the simpler one,” as Chris Simms describes it. With some of the arguments from RMP approaching this almost ‘magical’ solution, Hart is at pains to argue that indeed the simplest explanation for the mind-like structure of reality is that it is indeed Mind. 

 I believe this to be a crucial book in the ongoing dialogue between philosophers and theologians on the one hand and the sciences on the other. The project of pointing out the philosophical problems with the dominant paradigm is a difficult when the other side rarely wishes to listen; Hart, however, is a voice that cannot be ignored.

Will AI’s attentions amplify or suffocate us?

Keeping attention on the right things has always been a problem.

Taking inspiration from human attention has made AI vastly more powerful. Can this focus our minds on why attention really matters? 

Artificial intelligence has been developing at a dizzying rate. Chatbots like ChatGPT and Copilot can automate everyday tasks and can effortlessly summarise information. Photorealistic images and videos can be generated from a couple of words and medical AI promises to revolutionise both drug discovery and healthcare. The technology (or at least the hype around it) gives an impression of boundless acceleration. 

So far, 2025 has been the year AI has become a real big-ticket political item. The new Trump administration has promised half a trillion dollars for AI infrastructure and UK prime minister Keir Starmer plans to ‘turbocharge’ AI in the UK. Predictions of our future with this new technology range from doom-laden apocalypse to techno-utopian superabundance. The only certainty is that it will lead to dramatic personal and social change. 

This technological impact feels even more dramatic given the relative simplicity of its components. Huge volumes of text, image and videos are converted into vast arrays of numbers. These grids are then pushed through repeated processes of addition, multiplication and comparison. As more data is fed into this process, the numbers (or weights) in the system are updated and the AI ‘learns’ from the data. With enough data, meaningful relationships between words are internalised and the model becomes capable of generating useful answers to questions. 

So why have these algorithms become so much more powerful over the past few years? One major driver has been to take inspiration from human attention. An ‘attention mechanism’ allows very distant parts of texts or images to be associated together. This means that when processing a passage of conversation in a novel, the system is able to take cues on the mood of the characters from earlier in the chapter. This ability to attend to the broader context of the text has allowed the success of the current wave of ‘large language models’ or ‘generative AI’. In fact, these models with the technical name ‘Transformer’ were developed by removing other features and concentrating only on the attention mechanisms. This was first published in the memorably named ‘Attention is All You Need’ paper written by scientists working at Google in 2017. 

If you’re wondering whether this machine replication of human attention has much to do with the real thing, you might be right to be sceptical. That said, this attention-imitating technology has profound effects on how we attend to the world. On the one hand, it has shown the ability to focus and amplify our attention, but on the other, to distract and suffocate it. 

Attention is a moral act, directed towards care for others.

A radiologist acts with professional care for her patients. Armed with a lifetime of knowledge and expertise, she diligently checks scans for evidence of malignant tumours. Using new AI tools can amplify her expertise and attention. These can automatically detect suspicious patterns in the image including very fine detail that a human eye could miss. These additional pairs of eyes can free her professional attention to other aspects of the scan or other aspects of the job. 

Meanwhile, a government acts with obligations to keep its spending down. It decides to automate welfare claim handling using a “state of the art” AI system. The system flags more claimants as being overpaid than the human employees used to. The politicians and senior bureaucrats congratulate themselves on the system’s efficiency and they resolve to extend it to other types of payments. Meanwhile, hundreds of thousands are being forced to pay non-existent debts. With echoes of the British Post Office Horizon Scandal, the 2017-2020 the Australian Robo-debt scandal was due to flaws in the algorithm used to calculate the debts. To have a properly functioning welfare safety net, there needs to be public scrutiny, and a misplaced deference to machines and algorithms suffocated the attention that was needed.   

These examples illustrate the interplay between AI and our attention, but they also show that human attention has a broader meaning than just being the efficient channelling of information. In both cases, attention is a moral act, directed towards care for others. There are many other ways algorithms interact with our attention – how social media is optimised to keep us scrolling, how chatbots are being touted as a solution to loneliness among the elderly, but also how translation apps help break language barriers. 

Algorithms are not the first thing to get in the way of our attention, and keeping our attention on the right things has always been a problem. One of the best stories about attention and noticing other people is Jesus’ parable of the Good Samaritan. A man lies badly beaten on the side of the road after a robbery. Several respectable people walk past without attending to the man. A stranger stops. His people and the injured man’s people are bitter enemies. Despite this, he generously attends to the wounded stranger. He risks the danger of stopping – perhaps the injured man will attack him? He then tends the man’s wounds and uses his money to pay for an indefinite stay in a hotel. 

This is the true model of attention. Risky, loving “noticing” which is action as much as intellect. A model of attention better than even the best neuroscientist or programmer could come up with, one modelled by God himself. In this story, the stranger, the Good Samaritan, is Jesus, and we all sit wounded and in need of attention. 

But not only this, we are born to imitate the Good Samaritan’s attention to others. Just as we can receive God’s love, we can also attend to the needs of others. This mirrors our relationship to artificial intelligence, just as our AI toys are conduits of our attention, we can be conduits of God’s perfect loving attention. This is what our attention is really for, and if we remember this while being prudent about the dangers of technology, then we might succeed in elevating our attention-inspired tools to make AI an amplifier of real attention.
