Why read Martin Luther today?

Innovative ideas around identity shaped the world around him.

Tensions build as the German election approaches. Money is flowing, bargaining going on behind the scenes. (We are talking the election of 1519 here). There is the favorite, Karl—they called him Carlos in the Spanish dominions he had  inherited from his maternal grandparents, Ferdinand and Isabella—, grandson of the German emperor, Maximilian of Austria, and there is the challenger, the King of France, Francis I, and there is the wild card, the duke of Saxony, one of the seven electors who would elect the next emperor, Frederick, called the Wise.  Frederick had no imperial ambitions, and he tipped the election to his distant cousin, the then young man we call Charles V.  Two years later, that gave Frederick the leverage to win a hearing for his most prominent professor at the pride of his heart, his new university in Wittenberg, Martin Luther. 

Charles regarded this Augustinian friar, who had been excommunicated at the beginning of 1521 by Pope Leo X, as a dangerous heretic.  He wanted to declare Luther a criminal, open for execution on the open road by whoever might find him and run him through.  Frederick advised the young emperor not to treat a German subject like that, so Charles arranged for Luther to come to the imperial diet in Worms in May 1521 to recant.  Luther explained to the emperor that he really could not recant since his writings contained many truths.  He continued, “I am bound by the Scriptures I have quoted, and my conscience is captive to the Word of God.”  Later reports say that he added the words, “I cannot do anything else. Here I stand. God help me!”  Whether he said “here I stand” or not, that is what Martin Luther did at Worms and continued to do for the next quarter century until his death. 

Upon what was he standing?  As a “doctor in Biblia,” a “teacher of the Scriptures,” Luther had taken up the latest methods of the so-called humanist movement for exploring ancient texts in their original languages.  Jurists turned to Justinian’s Code in sixth century Latin. Physicians were reading Galen’s medical advice in ancient Greek. Theologians immersed themselves in the Bible in Hebrew and Greek.  Luther had put the tools of these methods to use as he lectured in the 1510s on the Hebrew Psalms, and then the apostle Paul’s letters to the Romans and to the Galatians.  There he found a new way of viewing himself, the God whom he found speaking to him in the pages of the Bible, and his fellow human creatures.  He used the world “righteousness” in the way we might use “personal identity” today.  He heard from the biblical writers a different way of identifying who he was at his core by listening to God’s regard for him.

Just as our DNA is a gift, not something we have to work to earn, so Luther’s core identity came from outside himself.

Luther certainly did not deny that human performance helps give each human being a variety of identities as we go about what he saw as callings from God in our exercise of responsibilities in our homes, in our economic life, in our societal networks and political structures.  He believed that in these spheres of life we are active in shaping the way other people view and identify us.  But at his core, Luther found the person behind the masks of his everyday life to be unable to perform everything that would make him the good person he wanted to be, the good person he thought God wanted him to be.  Just as our DNA is a gift, not something we have to work to earn, so Luther’s core identity came from outside himself.  It came as a gift from God, his Creator.  He received it passively, and his trust in the God who gave him this passively bestowed identity set his entire life in order.  Because he trusted God to be his support and to justify who he was, he felt freed to perform his responsibilities toward other human creatures actively. 

Luther believed that on his own he had not been able to trust God, to love him and give him proper respect.  Like the modern psychiatrist and philosopher, Erik Erikson, Luther believed that trust forms the basis of human personhood and personality.  He saw that his trusting some Absolute and Ultimate formed his character and enabled him to function as a human being.  He recognized in the God presented by the Old Testament prophets of Israel and the New Testament evangelists and apostles the ultimate and absolute person, who approached the human creatures who had turned their backs on him by becoming one of them as Jesus of Nazareth.  In the mysterious ways of the Creator, Jesus’s death covered the transgressions and offenses, the mistakes and failures, of all human beings, and in his resurrection God gave new life, a new identity, true righteousness to those who trust in him. 

Luther found that message liberating.  It freed him from being imprisoned in a cycle of always insufficient attempts to be the person he wanted to be to please his Creator.  He rested in the unconditional love of this Creator, who had come face to face with humankind as the rabbi from Nazareth, crucified but back from death itself.  That freed Dr. Luther to be bonded to those within his reach who needed his care and love.  He need not manipulate them by doing them the good he needed to make himself look good in God’s sight and feel satisfied with himself.  He now could do them the good that they truly needed.  That gave his tempestuous spirit a sense of joy and peace. 

He lived out a rather peaceable life under the ban of church and empire, but safely ensconced in the lands of his Saxon electors.  Family life brought him much joy.  His judgment that God had given human beings the gift of sexuality for companionship and support as well as procreation made him uncomfortable with his own vows of celibacy, but not so uncomfortable that he would have married had not a nun named Katharina von Bora, who had left the cloister, laid claim to him.  Together they created a bustling household with their six children being raised in the cloister where Martin had lived as an Augustinian Brother, large enough to house students and guests from places far from Wittenberg.  Katharina served as his counsellor and theological conversation partner as well as the efficient manager of this ever-changing parade of co-inhabitants of their home. 

Music filled their home.  Luther’s firm tenor voice and his lute and his flute led family and visitors in evenings of song, sometimes giving voice to hymns he had written.  His sense of tone and rhythm coupled with sensitivity to the fine points of spoken and written speech made him a scholar of great skill and a translator who “looked into the mouths” of the people in the marketplace and render the Bible in their tongue.  His curiosity stimulated or at least supported colleagues at the university across the disciplines, including a botany instructor who took students the woods to look at leaves and colleagues in mathematics and astronomy who were playing with the new calculation of the heavens by Nikolaus Copernicus. 

Luther’s lively engagement with life and his dramatic search for peace in the pages of the Bible produced a man who enjoyed life despite his struggles with “melancholy,” a widespread disease of his time, and the threats of violence to his person that never disappeared.  His robust wrestling with the biblical texts provides even today stimulating, even provocative reading for anyone, who is looking for the heart of the matter, the matter of self and life.

Whether it's AI or us, it's OK to be ignorant

Our search for answers begins by recognising that we don’t have them.

When was the last time you admitted you didn’t know something? I don’t say it as much as I ought to. I’ve certainly felt the consequences of admitting ignorance – of being ridiculed for being entirely unaware of a pop culture reference, of being found out that I wasn’t paying as close attention to what my partner was saying as she expected. In a hyper-connected age when the wealth of human knowledge is at our fingertips, ignorance can hardly be viewed as a virtue. 

A recent study on the development of artificial intelligence holds out more hope for the value of admitting our ignorance than we might have previously imagined. Despite wide-spread hype and fearmongering about the perils of AI, our current models are in many ways developed in similar ways to how an animal is trained. An AI system such as ChatGPT might have access to unimaginable amounts of information, but it requires training by humans on what information is valuable or not, whether it has appropriately understood the request it has received, and whether its answer is correct. The idea is that human feedback helps the AI to hone its model through positive feedback for correct answers, and negative feedback for incorrect answers, so that it keeps whatever method led to positive feedback and changes whatever method led to negative feedback. It really isn’t that far away from how animals are trained. 

However, a problem has emerged. AI systems have become adept at giving coherent and convincing sounding answers that are entirely incorrect. How has this happened? 

This is a tool; it is good at some tasks, and less good at others. And, like all tools, it does not have an intrinsic morality. 

In digging into the training method for AI, the researchers found that the humans training the AI flagged answers of “I don’t know” as unsatisfactory. On one level this makes sense. The whole purpose of these systems is to provide answers, after all. But rather than causing the AI to return and rethink its data, it instead developed increasingly convincing answers that were not true whatsoever, to the point where the human supervisors didn’t flag sufficiently convincing answers as wrong because they themselves didn’t realise that they were wrong. The result is that “the more difficult the question and the more advanced model you use, the more likely you are to get well-packaged, plausible nonsense as your answer.” 

Uncovering some of what is going on in AI systems dispels both the fervent hype that artificial intelligence might be our saviour, and the deep fear that it might be our societal downfall. This is a tool; it is good at some tasks, and less good at others. And, like all tools, it does not have an intrinsic morality. Whether it is used for good or ill depends on the approach of the humans that use it. 

But this study also uncovers our strained relationship with ignorance. Problems arise in the answers given by systems like ChatGPT because a convincing answer is valued more than admitting ignorance, even if the convincing answer is not at all correct. Because the AI has been trained to avoid admitting it doesn’t know something, all of its answers are less reliable, even the ones that are actually correct.  

This is not a problem limited to artificial intelligence. I had a friend who seemed incapable of admitting that he didn’t know something, and whenever he was corrected by someone else, he would make it sound like his first answer was actually the correct one, rather than whatever he had said. I don’t know how aware he was that he did this, but the result was that I didn’t particularly trust whatever he said to be correct. Paradoxically, had he admitted his ignorance more readily, I would have believed him to be less ignorant. 

It is strange that admitting ignorance is so avoided. After all, it is in many ways our default state. No one faults a baby or a child for not knowing things. If anything, we expect ignorance to be a fuel for curiosity. Our search for answers begins in the recognition that we don’t have them. And in an age where approximately 500 hours of video is uploaded to YouTube every minute, the sum of what we don’t know must by necessity be vastly greater than all that we do know. What any one of us can know is only a small fraction of all there is to know. 

Crucially, admitting we do not know everything is not the same as saying that we do not know anything

One of the gifts of Christian theology is an ability to recognize what it is that makes us human. One of these things is the fact that any created thing is, by definition, limited. God alone is the only one who can be described by the ‘omnis’. He is omnipotent, omnipresent, and omniscient. There is no limit to his power, and presence, and knowledge. The distinction between creator and creation means that created things have limits to their power, presence, and knowledge. We cannot do whatever we want. We cannot be everywhere at the same time. And we cannot know everything there is to be known.  

Projecting infinite knowledge is essentially claiming to be God. Admitting our ignorance is therefore merely recognizing our nature as created beings, acknowledging to one another that we are not God and therefore cannot know everything. But, crucially, admitting we do not know everything is not the same as saying that we do not know anything. Our God-given nature is one of discovery and learning. I sometimes like to imagine God’s delight in our discovery of some previously unknown facet of his creation, as he gets to share with us in all that he has made. Perhaps what really matters is what we do with our ignorance. Will we simply remain satisfied not to know, or will it turn us outwards to delight in the new things that lie behind every corner? 

For the developers of ChatGPT and the like, there is also a reminder here that we ought not to expect AI to take on the attributes of God. AI used well in the hands of humans may yet do extraordinary things for us, but it will not truly be able to do anything, be everywhere, or know everything. Perhaps if it was trained to say ‘I don’t know’ a little more, we might all learn a little more about the nature of the world God has made.
