Can AI have free will?

This is a question I’ve never seen asked, let alone answered. I think there are good reasons for that, which I’ll come to later.
 
The latest issue of Philosophy Now (Issue 159, Dec 2023/Jan 2024), which I’ve already referred to in 2 previous posts, has as its theme (they always have a theme), Freewill Versus Determinism. I’ll concentrate on an article by the Editor, Grant Bartley, titled What Is Free Will? That’s partly because he and I have similar views on the topic, and partly because reading the article led me to ask the question at the head of this post (I should point out that he never mentions AI).
 
It's a lengthy article, meaning I won’t be able to fully do it justice, or even cover all aspects that he discusses. For instance, towards the end, he posits a personal ‘pet’ theory that there is a quantum aspect to the internal choice we make in our minds. And he even provides a link to videos he’s made on this topic. I mention this in passing, and will make 2 comments: one, I also have ‘pet’ theories, so I can’t dismiss him out-of-hand; and two, I haven’t watched the videos, so I can’t comment on its plausibility.
 
He starts with an attempt to define what we mean by free will, and what it doesn’t mean. For instance, he differentiates between subconscious choices, which he calls ‘impulses’ and free will, which requires a conscious choice. He also differentiates what he calls ‘making a decision’. I will quote him directly, as I still see this involving free will, if it’s based on making a ‘decision’ from alternative possibilities (as he explains).
 
…sometimes, our decision-making is a choice, that is, mentally deciding between alternative possibilities present to your awareness. But your mind doesn’t always explicitly present you with multiple choices from which to choose. Sometimes no distinct options are present in your awareness, and you must cause your next contents of your mind on the basis of the present content, through intuition and imagination. This is not choice so much as making a decision. (My emphasis)
 
This is worth a detour, because I see what he’s describing in this passage as the process I experience when writing fiction, which is ‘creating’. In this case, some of the content, if not all of it, is subconscious. When you write a story, it feels to you (but no one else) that the characters are real and the story you’re telling already exists. Nevertheless, I still think there’s an element of free will, because you make choices and judgements about what your imagination presents to your consciousness. As I said, this is a detour.
 
I don’t think this is what he’s referring to, and I’ll come back to it later when I introduce AI into the discussion. Meanwhile, I’ll discuss what I think is the nub of his thesis and my own perspective, which is the apparent dependency between consciousness and free will.
 
If conscious causation is not real, why did consciousness evolve at all? What would be the function of awareness if it can’t change behaviour? How could an impotent awareness evolve if it cannot change what the brain’s going to do to help the human body or its genes survive? (Italics in the original)
 
This is a point I’ve made myself, but Bartley goes further and argues “Since determinism can’t answer these questions, we can know determinism is false.” This is the opposite to Sabine Hossenfelder’s argument (declaration really) that ‘free will is an illusion [therefore false]’.
 
Note that Bartley coins the term, ‘conscious causation’, as a de facto synonym for free will. In fact, he says this explicitly in his conclusion: “If you say there is no free will, you’re basically saying there is no such thing as conscious causation.” I’d have to agree.
 
I made the point in another post that consciousness seems to act outside the causal chain of the Universe, and I feel that’s what Bartley is getting at. In fact, he explicitly cites Kant on this point, who (according to Bartley) “calls the will ‘transcendental’…” He talks at length about ‘soft (or weak) determinism’ and ‘strong determinism’, which I’ve also discussed. Now, the usual argument is that consciousness is ‘caused’ by neuron activity, therefore strong determinism is not broken.
 
To quote Hossenfelder: Your brain is running a calculation, and while it is going on you do not know the outcome of that calculation. So the impression of free will comes from our ‘awareness’ that we think about what we do, along with our inability to predict the result of what we are thinking. (Hossenfelder even uses the term ‘software’ to describe what does the ‘calculating’ in your brain.)
 
And this allows me to segue into AI, because what Hossenfelder describes is what we expect a computer to do. The thing is that while most scientists (and others) believe that AI will eventually become conscious (not sure what Hossenfelder thinks), I’ve never heard or seen anyone argue that AI will have free will. And this is why I don’t think the question at the head of this post has ever been asked. Many of the people who believe that AI will become conscious also don’t believe free will exists.
 
There is another component to this, which I’ve raised before and that’s imagination. I like to quote Raymond Tallis (neuroscientist and also a contributor to Philosophy Now).
 
Free agents, then, are free because they select between imagined possibilities, and use actualities to bring about one rather than another. (My emphasis)
 
Now, in another post, I argued that AI can’t have imagination in the way we experience it, yet I acknowledge that AI can look at numerous possibilities (like in a game of chess) and 'choose' what it ‘thinks’ is the optimum action. So, in this sense, AI would have ‘agency’, but that’s not free will, because it’s not ‘conscious causation’. And in this sense, I agree with Bartley that ‘making a decision’ does not constitute free will, if it’s what an AI does. So the difference is consciousness. To quote from that same post on this topic.
 
But the key here is imagination. It is because we can imagine a future that we attempt to bring it about - that's free will. And what we imagine is affected by our past, our emotions and our intellectual considerations, but that doesn't make it predetermined.
 
So, if imagination and consciousness are both faculties that separate us from AI, then I can’t see AI having free will, even though it will make ‘decisions’ based on data it receives (as inputs), and those decisions may not be predictable.
 
And this means that AI may not be deterministic either, in the ‘strong’ sense. One of the differences with humans, and other creatures that evolved consciousness, is that consciousness can apparently change the neural pathways of the brain, which I’d argue is the ‘strange loop’ posited by Douglas Hofstadter. (I have discussed free will and brain-plasticity in another post)
 
But there’s another way of looking at this, which differentiates humans from AI. Our decision-making is a combination of logical reasoning and emotion. AI only uses logic, and even then, it uses logic differently to us. It uses a database of samples and possibilities to come up with a ‘decision’ (or output), but without using the logic to arise at that decision the way we would. In other words, it doesn’t ‘understand’ the decision, like when it translates between languages, for example.
 
There is a subconscious and conscious component to our decision-making. Arguably, the subconscious component is analogous to what a computer does with algorithm-based software (as per Hossenfelder’s description). But there is no analogous conscious component in AI, which makes a choice or decision. In other words, there is no ‘conscious causation’, therefore no free will, as per Bartley’s definition.
 

How can we achieve world peace?

 Two posts ago, I published my submission to Philosophy Now's Question of the Month, from 2 months ago: What are the limit of knowledge? Which was published in Issue 159 (Dec 2023/Jan 2024). Logically, they inform readers of the next Question of the Month, which is the title of this post. I'm almost certain they never publish 2 submissions by the same author in a row, so I'm publishing this answer now. It's related to my last post, obviously, and one I wrote some time ago (Humanity's Achilles Heel).

There are many aspects to this question, not least whether one is an optimist or a pessimist. It’s well known that people underestimate the duration and cost of a project, even when it’s their profession, because people are optimists by default. Only realists are pessimistic, and I’m in the latter category, because I estimate the duration of projects professionally.
 
There are a number of factors that mitigate against world peace, the primary one being that humans are inherently tribal and are quick to form ingroup-outgroup mental-partitions, exemplified by politics the world over. In this situation, rational thought and reasoned argument take a back seat to confirmation bias and emotive rhetoric. Add to this dynamic, the historically observed and oft-repeated phenomena that we follow charismatic, cult-propagating leaders, and you have a recipe for self-destruction on a national scale. This is the biggest obstacle to world peace. These leaders thrive on and cultivate division with its kindred spirits of hatred and demonisation of the ‘other’: the rationale for all of society’s ills becomes an outgroup identified by nationality, race, skin-colour, culture or religion.
 
Wealth, or the lack of it, is a factor as well. Inequality provides a motive and a rationale for conflict. It often goes hand-in-hand with oppression, but even when it doesn’t, the anger and resentment can be exploited and politicised by populist leaders, whose agenda is more focused on their own sense of deluded historical significance than actually helping the people they purportedly serve.
 
If you have conflict - and it doesn’t have to be military – then as long as you have leaders who refuse to compromise, you’ll never find peace. Only moderates on both sides can broker peace.
 
So, while I’m a pessimist or realist, I do see a ‘how’. If we only elect leaders who seek and find consensus, and remove leaders who sow division, there is a chance. The best leaders, be they corporate, political or on a sporting field, are the ones who bring out the best in others and are not just feeding their own egos. But all this is easier said than done, as we are witnessing in certain parts of the world right now. For as long as we elect leaders who are narcissistic and cult-like, we will continue to sow the seeds of self-destruction.

Addendum: This was published in Issue 161. So it's the first time they've published 2 of my submissions in a row.

Bad things happen when good people do nothing

 At present there are 2 conflicts holding the world’s attention – they are different, yet similar. They both involve invasions, one arguably justified, involving a response to a cowardly attack, and the other based on the flimsiest of suppositions. But what they highlight is a double-standard in the policies of Western governments in how they respond to the humanitarian crises that inevitably result from such incursions.
 
I’m talking about the war in Ukraine, following Russia’s invasion 2 years ago next month, and Israel’s war in Gaza, following Hamas’s attack on 7 Oct. 2023, killing around 1200 people and taking an estimated 240 hostages; a reported 120 still in captivity (at the time of writing).
 
According to the UN, 'Gaza faces the "highest ever recorded" levels of food insecurity', as reported on the Guardian website (21 Dec 2023). And it was reported on the news today (6 Jan 2024) that ‘Gaza is uninhabitable’. Discussions within the UN have been going on for over a month, yet have been unable to unlock a stalemate concerning humanitarian aid that requires a cessation of hostilities, despite the obvious existential need.
 
Noelia Monge, the head of emergencies for Action Against Hunger, said: “Everything we are doing is insufficient to meet the needs of 2 million people. It is difficult to find flour and rice, and people have to wait hours to access latrines and wash themselves. We are experiencing an emergency like I have never seen before.” (Source: Guardian)
 
I don’t think it’s an exaggeration to say that this is a humanitarian crisis of unprecedented proportions in modern times. It’s one thing for Israel to invade a country that harbours a mortal enemy, but it is another to destroy all infrastructure, medical facilities and cut off supplies of food and essential services, without taking any responsibility. And this is the double-standard we are witnessing. Everyone in the West condemns Putin’s attack on Ukrainian civilians, their homes and infrastructure, and calls them out as ‘war crimes’. No one has the courage to level the same accusation at Benjamin Netanyahu, despite the growing, unprecedented humanitarian crisis created by his implacable declaration to ‘destroy Hamas’. Has anyone pointed out that it’s impossible to destroy Hamas without destroying Gaza? Because that’s what he’s demonstrating.
 
The UN’s hunger monitoring system, Integrated Food Security Phase Classification (IPC), issued a report saying the “most likely scenario” in Gaza is that by 7 February “the entire population in the Gaza Strip [about 2.2 million people] would be at “crisis or worse” levels of hunger. (Source: Guardian)
 
In America, you have the perverse situation where many in the Republican Party want to withdraw support from Volodymyr Zelensky while providing military aid to Israel. They are, in effect, supporting both invasions, though they wouldn’t couch it in those terms.
 
Israel has a special status in Western eyes, consequential to the unconscionable genocide that Jews faced under Nazi Germany. It has led to a tendency, albeit unspoken, that Israel has special privileges when it comes to defending their State. This current conflict is a test of the West’s conscience. How much of a moral bankruptcy are we willing to countenance, before we say enough is enough, and that humanity needs to win.

Modes of expression in writing fiction

As I point out in the post, this is a clumsy phrase, but I find it hard to come up with a better one. It’s actually something I wrote on Quora in response to a question. I’ve written on this before, but this post has the benefit of being much more succinct while possibly just as edifying.
 
I use the term ‘introspection’ where others use the word, ‘insight’. It’s the reader’s insight but the character’s introspection, which is why I prefer that term in this context.
 
The questioner is Clxudy Pills, obviously a pseudonym. I address her directly in the answer, partly because, unlike other questions I get, she has always acknowledged my answers.
 

Is "show, not tell" actually a good writing tip?
 
Maybe. No one said that to me when I was starting out, so it had no effect on my development. But I did read a book (more than one, actually) on ‘writing’ that delineated 5 categories of writing ‘style’. Style in this context means the mode of expression rather than an author’s individual style or ‘voice’. That’s clumsily stated but it will make sense when I tell you what they are.
 

1. Dialogue is the most important because it’s virtually unique to fiction; quotes provided in non-fiction notwithstanding. Dialogue, more than any other style, tells you about the characters and their interactions with others.


   
   
2. Introspection is what the character thinks, effectively. This only happens in novels and short stories, not screenplays or stage plays, soliloquies being the exception and certainly not the rule. But introspection is essential to prose, especially when the character is on their own.


   
   
3. Exposition is the ‘telling’, not showing, part. When you’re starting out and learning your craft, you tend to write a lot of exposition – I know I did – which is why we get the admonition in your question. But the exposition can be helpful to you, if not the reader, as it allows you to explore the setting, the context of the story and its characters. Eventually, you’ll learn not to rely on it. Exposition is ‘smuggled’ into movies through dialogue and into novels through introspection.


   
   
4. Description is more difficult than you think, because it’s the part of a novel that readers will skip over to get on with the story. Description can be more boring than exposition, yet it’s necessary. My approach is to always describe a scene from a character’s POV, and keep it minimalist. Readers automatically fill in the details, because we are visual creatures and we do it without thinking.


   
   
5. Action is description in motion. Two rules: stay in one character’s POV and keep it linear – one thing happens after another. It has the dimension of time, though it’s subliminal.

 
 So there: you get 5 topics for the price of one.
