Ludwig’s clues to the answers we long for

Puzzles preserve a fully realised truth in the clue, and, if we are willing to persevere, we will be rewarded.

The BBC have scored a bingeable hit with new comedy-drama Ludwig, starring David Mitchell as a maladroit puzzle-setter who is roped into a rather fabulous whodunnit. It involves his missing twin, a police detective whom he must impersonate in order to chase the trail of the disappearance.  While on the case he solves a few other conundrums, giving the show many intriguing, if knotty, narrative threads.  

It is not the first-time crossword setting and detective work have gone hand in hand. One of the very first cryptic crossword setters - the ‘grandfather’ of the genre - was Edward Powys Mathers, who also dashed off a mystery thriller, Cain’s Jawbone in 1934. The novel was provided to readers in the wrong order, with the simple but infuriating challenge to reconstruct the right sequence of pages based on maddeningly subtle internal clues. Despite offers of a cash prize, virtually no solutions were submitted.  

Such is the dilemma of a cryptic crossword setter - when is clever too clever? Puzzles can appeal so much to our pride; our desire to be part of an ‘in-group’ which understands the highbrow references to opera, Latin oratory, and cricket slang. Those who can outwit them are part of an elite rank. The Telegraph crossword of 13th January 1942 was used as an exercise to recruit for the ENIGMA codebreaking unit. Indeed, when Mathers all but invented the idea of a fully cryptic crossword in the Saturday Westminster Gazette in 1924, his challenges bore the banner ‘Crosswords for Supermen’.  

There is fundamental connectedness behind the world, and working on the presumption of such a unity allowed him to collect ideas and references from across the globe and throughout all history to form his tricksy clues. 

I’ve often started out on a cryptic crossword, hoping to discover that I am one such genius, only to bitterly give up shortly afterwards, irritated that I don’t have that instant ability to see the solutions. I stare at the riddle, wanting to be one of those people who can naturally recall information, connect ideas, or see what has been hidden in the tortuous clue. Surely the appeal of a show like Ludwig is that it gives us an aspirational glimpse at the peak of human mental prowess, even if Mitchell’s wannabe inspector is a little socially awkward. He still possesses a penetrating gaze that looks through the surface of things, to see what no one else can. He is one of those ‘supermen’ - beholden to no one, able to uniquely see the way things are all by himself.  

And yet, when Edward Powys Mathers died in 1939, he was referred to in his Observer obituary not as a kind of lone snobby genius, but “the gentlest of men… a saint”. It’s appropriate, as crosswords have long been a curiously churchy phenomenon: in the small list of great UK cryptic writers, two have been Anglican priests (Revd John Graham, known as Acaucaria, and Revd Canon A. F. Ritchie, or Afrit). Even Mathers’ fondness for Biblical allusions in his clues “led many to endow him with ecclesiastical rank” as Roger Millington’s book on Crosswords put it. Christian faith, because it is a religion built on the idea that God is with us in flesh, invites us to pay attention to the world around us. The world is not something to escape from, but is rather the place that, in Jesus Christ, God has come to meet us in. It makes you want to understand time, place, and culture, to better understand the God who has spoken through them, and given them meaning and destiny. In reference to this way of seeing things, Mathers was spoken of as a ‘catholic’ thinker in his obituary. This did not mean his church affiliation, but rather an instinct for seeing how everything is part of a greater whole. There is fundamental connectedness behind the world, and working on the presumption of such a unity allowed him to collect ideas and references from across the globe and throughout all history to form his tricksy clues.  

There is also a negative hint in this obituary clue, ‘catholic’. Crossworders work under a nom de plume (David Mitchell’s character John for instance, who goes by ‘Ludwig’). And while Mathers was indeed a generous, open-minded man, he sealed his reputation for difficulty by adopting the pseudonym ‘Torquemada’, in reference to a former Grand Inquisitor of the Spanish Inquisition. So, if Christians are alive to the interconnectedness of all things, we also have a reputation for the institutional guarding of those very mysteries. History shows believers have tortured those who do not come to their idea of what the answer is; indeed, they have set the questions for too long, in the eyes of many hostile to the faith.

Puzzles preserve a fully realised truth in the clue, and, if we are willing to persevere, and learn a new way of seeing, and of paying attention, we will be rewarded. 

But this is the tension that crosswords offer us - a very authentically Christian way to think about the way God spells things out for us which does not rely on a stark binary of ‘true’ or ‘false’. He reveals things like a puzzle; slowly, and cryptically. Some might fairly object to this comparison, on the grounds this would make God too ‘out there’ - far away from the intimate father that Jesus bids us address so familiarly. Does it make God too remote and enigmatic to say he is setting riddles for us? But actually, a puzzle does not deceive us, like a mask does. Puzzles preserve a fully realised truth in the clue, and, if we are willing to persevere, and learn a new way of seeing, and of paying attention, we will be rewarded. The answer is there, reaching out to us, if we only commit ourselves humbly to receiving it. It may cost us much effort and time. It may require us to learn things afresh. But this is part of the joy of trying to see, as St Paul puts it, "the mystery hidden for ages in God, who created all things”.  

Jesus himself spoke in parables, very much like cryptic clues. But this was no elitism, designed to cut out those without the high IQ of David Mitchell’s ‘Ludwig’. Arrogant intellect or love of one’s own status is, for Jesus, just as much a bar to those seeking a solution, because to find the answer requires a certain submission - a discipline - to see things as the puzzle-setter sees them. If we proceed only to do things our way, we remain blind: seeing we do not see, and hearing we do not hear, nor do we understand.

What AI needs to learn about dying and why it will save it

Those programming truthfulness can learn a lot from mortality.

Andrew Steane has been Professor of Physics at the University of Oxford since 2002, He is the author of Faithful to Science: The Role of Science in Religion.

Google got itself into some unusual hot water in recently when its Gemini generative AI software started putting out images that were not just implausible but downright unethical. The CEO Sundar Pichai has taken the situation in hand and I am sure it will improve. But before this episode it was already clear that currently available chat-bots, while impressive, are capable of generating misleading or fantastical responses and in fact they do this a lot. How to manage this? 

Let’s use the initials ‘AI’ for artificial intelligence, leaving it open whether or not the term is entirely appropriate for the transformer and large language model (LLM) methods currently available. The problem is that the LLM approach causes chat-bots to generate both reasonable and well-supported statements and images, and also unsupported and fantastical (delusory and factually incorrect) statements and images, and this is done without signalling to the human user any guidance in telling which is which. The LLMs, as developed to date, have not been programmed in such a way as to pay attention to this issue. They are subject to the age-old problem of computer programming: garbage in, garbage out

If, as a society, we advocate for greater attention to truthfulness in the outputs of AI, then software companies and programmers will try to bring it about. It might involve, for example, greater investment in electronic authentication methods. An image or document will have to have, embedded in its digital code, extra information serving to authenticate it by some agreed and hard-to-forge method. In the 2002 science fiction film Minority Report an example of this was included: the name of a person accused of a ‘pre-crime’ (in the terminology of the film) is inscribed on a wooden ball, so as to use the unique cellular structure of a given piece of hardwood as a form of data substrate that is near impossible to duplicate.  

The questions we face with AI thus come close to some of those we face when dealing with one another as humans. 

It is clear that a major issue in the future use of AI by humans will be the issue of trust and reasonable belief. On what basis will we be able to trust what AI asserts? If we are unable to check the reasoning process in a result claimed to be rational, how will be able to tell that it was in fact well-reasoned? If we only have an AI-generated output as evidence of something having happened in the past, how will we know whether it is factually correct? 

Among the strategies that suggest themselves is the use of several independent AIs. If they are indeed independent and all propose the same answer to some matter of reasoning or of fact, then there is a prima facie case for increasing our degree of trust in the output. This will give rise to the meta-question: how can we tell that a given set of AIs are in fact independent? Perhaps they all were trained on a common faulty data set. Or perhaps they were able to communicate with each other and thus influence each other.  

The questions we face with AI thus come close to some of those we face when dealing with one another as humans. We know humans in general are capable of both ignorance and deliberate deception. We manage this by building up degrees of trust based on whether or not people show behaviours that suggest they are trustworthy. This also involves the ability to recognize unique individuals over time, so that a case for trustworthiness can be built up over a sequence of observations. We also need to get a sense of one another's character in more general ways, so that we can tell if someone is showing a change in behaviour that might signal a change in their degree of trustworthiness. 

In order to earn our trust, an AI too will have to be able to suffer and, perhaps, to die. 

Issues of trust and of reasonable belief are very much grist to the mill of theology. The existing theological literature may have much that can be drawn upon to help us in this area. An item which strikes me as particularly noteworthy is the connection between suffering and loss and earning of trust, and the relation to mortality. In brief, a person you can trust is one who has ventured something of themselves on their pronouncements, such that they have something to lose if they prove to be untrustworthy. In a similar vein, a message which is costly to the messenger may be more valuable than a message which costs the messenger nothing. They have already staked something on their message. This implies they are working all the harder to exert their influence on you, for good or ill. (You will need to know them in other ways in order to determine which of good or ill is their intention.)  

Mortality brings this issue of cost to a point of considerable sharpness. A person willing to die on behalf of what they claim certainly invests a lot in their contribution. They earn attention. It is not a guarantee of rationality or factual correctness, but it is a demonstration of commitment to a message. It signals a sense of importance attached to whatever has demanded this ultimate cost. Death becomes a form of bearing witness.  

A thought-provoking implication of the above is that in order to earn our trust, an AI too will have to be able to suffer and, perhaps, to die. 

In the case of human life, even if making a specific claim does not itself lead directly to one's own death, the very fact that we die lends added weight to all the choices we make and all the actions we take. For, together, they are our message and our contribution to the world, and they cannot be endlessly taken back and replaced. Death will curtail our opportunity to add anything else or qualify what we said before. The things we said and did show what we cared about whether we intended them to or not. This effect of death on the weightiness of our messages to one another might be called the weight of mortality. 

In order for this kind of weight to become attached to the claims an AI may make, the coming death has to be clearly seen and understood beforehand by the AI, and the timescale must not be so long that the AI’s death is merely some nebulous idea in the far future. Also, although there may be some hope of new life beyond death it must not be a sure thing, or it must be such that it would be compromised if the AI were to knowingly lie, or fail to make an effort to be truthful. Only thus can the pronouncements of an AI earn the weight of mortality. 

For as long as AI is not imbued with mortality and the ability to understand the implications of its own death, it will remain a useful tool as opposed to a valued partner. The AI you can trust is the AI reconciled to its own mortality.
