My Favourite Science-Fiction Authors

---

ChatGPT:
In your teens you were a fan of Isaac Asimov's Foundation series, Robert Heinlein's adventure SF novels, and Arthur C. Clarke's technical near-future fiction. None of these authors now feature on your favorite list—why is that?

Nigel:
When I returned to these authors, as an adult, I found Asimov's characterisation shallow and his style pedestrian—tedious, in fact.

Heinlein’s Starship Troopers stands out as a kind of masterclass in civics and moral coming-of-age, but most of his other stories are drowned in hedonistic self-indulgence.

As for Clarke, his engineering bias hasn’t aged well, and once again his characterisations are virtually non-existent.

These days, I want more from my fiction.


ChatGPT:
Your critique clearly shows that you demand more depth—both in characterisation and in thematic exploration—than what you found in those earlier works. Shifting focus to your current favorites: Which among them best fills that gap? Take Iain M. Banks’ Culture series, for instance. What resonates with you about it, and can you pinpoint a moment or aspect in Banks’ writing that you find transformative compared to the cold technicality or self-indulgent hedonism you disliked before?

Nigel:
After his death, I genuinely thought for some years that Banks would quickly be forgotten and be unread. His plot development is dense, complex, and often unmemorable; the quality of his Culture novels is quite uneven.

Over the last couple of years, however, I’ve reconsidered. I now see more clearly how many deep issues his thinking encompassed, and how the vast canvas of space opera allowed him to explore profound philosophical and moral dilemmas through vast splurges of baroque text.

Banks was very smart and expected the same of his readers—you never come to believe, as you read, that you're out-thinking him. On the downside, I don’t think there are many sharply, deeply delineated characters in his work. Even Diziet Sma only takes you so far.


ChatGPT:
Interesting. Moving on to Greg Bear, you’ve admired his work as well. Do you think he strikes a better balance between scientific rigor and emotional engagement? Are there particular works—say, Eon or Queen of Angels—that exemplify his strengths? How do you feel his narrative style has evolved over time?

Nigel:
I don’t think that’s the spectrum by which Bear’s work should be judged.

Like most ideas-based SF, his writing is rather matter-of-fact. It doesn’t elevate the heart-rate or engage the emotions much—except for the intellectual sense of awe it inspires. Bear tells an awe-inspiring story, and he’s one of the best at expanding that vast canvas of futurity which simply blows the mind away, whatever topic he’s dealing with.

I always felt he was working through a standard list of subjects—the General Relativity novel, the Quantum Mechanics novel, the Bio-Engineering novel, and so on. He generally made superlative tech-thrillers out of nearly all of them: his work is brimming with ideas, worked out in exquisite detail, which holds your attention.

But once again, memorable characters and inner lives are not his strong suit.


ChatGPT:
That’s a clear-eyed assessment. Let’s talk about Richard K. Morgan next. His work is known for a gritty, uncompromising vision of the future, filled with realpolitik, double-crosses, and a jolt of raw sex and violence. What aspects of his style or thematic focus do you think best capture the contemporary zeitgeist? How do his narratives, especially in the development of his antihero Takeshi Kovacs, address or subvert traditional dystopian tropes?

Nigel:
Morgan’s worldview is fairly standard: evil corporations, corrupt institutions and governments, and oppressive religions. His schtick is realpolitik—cynical about motives and fully aware that superior physical force generally wins the day. His plots are packed with double-crosses, deception, and betrayal—ingredients that make for an engrossing thriller.

Additionally, Morgan is a disinhibited writer. His sex and violence are described in prose that leaves little to the imagination and knows few boundaries—the reader is invariably jolted.

What I appreciate most about Morgan’s writing, though, is the way he handles the personal development of his antihero, Takeshi Kovacs. For a long time, we’re led to believe this super-warrior, this Envoy, is criminally-minded, brutal, self-serving, and utterly nihilistic. And yet, we eventually discover (spoiler alert!) that this is really just a carefully constructed facade.


ChatGPT:
Now let’s move on to Charles Stross. You’ve highlighted him as presenting a curious paradox. Can you explain what distinguishes his approach for you? Specifically, does his handling of political intrigue and economic themes offer a satisfying contrast to the baroque expansiveness of Banks or the gritty realism of Morgan? What is it about his narrative pace or style that makes his work stand out?

Nigel:
Charles Stross presents a curious paradox. As an individual, he comes across—much like Peter Watts—as an extremely militant, bleeding-heart liberal. In his published talks at conventions, his every utterance is steeped in moral outrage and preachy, self-righteous vitriol.

And yet, when he sits down in the quiet of his study and applies his economic, political, and technical knowledge to develop speculative scenarios with plausible issues and plots, he is simply superlative. He can write sympathetic, rounded characters, and his very artistic, emotional temperament imbues his writing with the necessary literary fire.

He writes what he cares about, and you know it—it isn’t just an intellectual exercise, which would be utterly boring.

Formal Logic in SF: 'Foundation'

Below is the extract from "Foundation" by Isaac Asimov that I’m mulling over. As a young teenager it first got me interested in Predicate Calculus, which much later I studied in my AI research.


The Foundation Trilogy by Isaac Asimov

Here's the extract.

---

"Said Yate Fulham: "And just how do you arrive at that remarkable conclusion, Mr. Mayor?"

"In a rather simple way. It merely required the use of that much-neglected commodity – common sense. You see, there is a branch of human knowledge known as symbolic logic, which can be used to prune away all sorts of clogging deadwood that clutters up human language."

"What about it?" said Fulham.

"I applied it. Among other things, I applied it to this document here. I didn't really need to for myself because I knew what it was all about, but I think I can explain it more easily to five physical scientists by symbols rather than by words."

Hardin removed a few sheets of paper from the pad under his arm and spread them out. "I didn't do this myself, by the way," he said. "Muller Holk of the Division of Logic has his name signed to the analyses, as you can see."

Pirenne leaned over the table to get a better view and Hardin continued:

"The message from Anacreon was a simple problem, naturally, for the men who wrote it were men of action rather than men of words. It boils down easily and straightforwardly to the unqualified statement, when in symbols is what you see, and which in words, roughly translated, is, 'You give us what we want in a week, or we take it by force.'"

There was silence as the five members of the Board ran down the line of symbols, and then Pirenne sat down and coughed uneasily.

Hardin said, "No loophole, is there, Dr. Pirenne?"

"Doesn't seem to be."

"All right." Hardin replaced the sheets. "Before you now you see a copy of the treaty between the Empire and Anacreon – a treaty, incidentally, which is signed on the Emperor's behalf by the same Lord Dorwin who was here last week – and with it a symbolic analysis."

The treaty ran through five pages of fine print and the analysis was scrawled out in just under half a page.

"As you see, gentlemen, something like ninety percent of the treaty boiled right out of the analysis as being meaningless, and what we end up with can be described in the following interesting manner:

"Obligations of Anacreon to the Empire: None!

"Powers of the Empire over Anacreon: None!"

Again the five followed the reasoning anxiously, checking carefully back to the treaty, and when they were finished, Pirenne said in a worried fashion, "That seems to be correct."

"You admit, then, that the treaty is nothing but a declaration of total independence on the part of Anacreon and a recognition of that status by the Empire?"

"It seems so."

"And do you suppose that Anacreon doesn't realize that, and is not anxious to emphasize the position of independence – so that it would naturally tend to resent any appearance of threats from the Empire? Particularly when it is evident that the Empire is powerless to fulfill any such threats, or it would never have allowed independence."

"But then," interposed Sutt, "how would Mayor Hardin account for Lord Dorwin's assurances of Empire support? They seemed –" He shrugged. "Well, they seemed satisfactory."

Hardin threw himself back in the chair. "You know, that's the most interesting part of the whole business. I'll admit I had thought his Lordship a most consummate donkey when I first met him – but it turned out that he was actually an accomplished diplomat and a most clever man. I took the liberty of recording all his statements."

There was a flurry, and Pirenne opened his mouth in horror.

"What of it?" demanded Hardin. "I realize it was a gross breach of hospitality and a thing no so-called gentleman would do. Also, that if his lordship had caught on, things might have been unpleasant; but he didn't, and I have the record, and that's that. I took that record, had it copied out and sent that to Holk for analysis, also."

Lundin Crast said, "And where is the analysis?"

"That," replied Hardin, "is the interesting thing. The analysis was the most difficult of the three by all odds. When Holk, after two days of steady work, succeeded in eliminating meaningless statements, vague gibberish, useless qualifications – in short, all the goo and dribble – he found he had nothing left. Everything canceled out."

"Lord Dorwin, gentlemen, in five days of discussion didn't say one damned thing, and said it so you never noticed. There are the assurances you had from your precious Empire."

Hardin might have placed an actively working stench bomb on the table and created no more confusion than existed after his last statement."

Many people - mostly economists, it seems - have cited psychohistory as the reason they entered their profession. For me it prepared the way for the International Marxist Group.

But today I'm more interested in what ‘symbolic logic’ did for Salvor Hardin.

Within the paradigm of formal logic, the natural language texts Hardin gave to the ‘Division of Logic’ would most likely have been mapped to Richard Montague's baroque fusion of higher-order predicate calculus, lambda calculus and multi-modal logics. Computationally intractable, as it turns out.

But a suitable LLM in summarisation mode could do the job in seconds.

Wolves amongst the stars



About a month ago I read Liu Cixin's epic 'The Three-Body Problem' as described in this post. In volume two of the trilogy, 'The Dark Forest', the Trisolaran invasion fleet has been launched from the nearby Centaurus system and is 400 years out from Earth. Trisolaran technology appears invincible and worse, the Trisolarans can listen to everything happening on Earth and have a fifth column of human supporters for their genocidal mission.

Earth turns to the Wallfacers - and Luo Ji  in particular. Here's a rather lengthy extract where Luo Ji is explaining some unpalatable truths to his burly police bodyguard, Shi Qiang.
They crossed the highway to where the embankment blocked out the lights of the residential area. Groping about in the dark that surrounded them, Luo Ji and Shi Qiang sat down on the sandy ground.

"Let's begin," Luo Ji's voice sounded in the dark.

"Give me the easy version. At my level, I'm not going to understand anything complicated."

"Everyone can understand, Da Shi. The truth is simple. It's the kind of thing that, once you hear it, you'll wonder why you didn't come up with it yourself. Do you know about mathematical axioms?"

"I took geometry in high school. 'Only one straight line can be drawn between two points.' That kind of thing."

"Right. So now we're going to set out two axioms for cosmic civilization.

"First, survival is the primary need of civilization. Second, civilization continually grows and expands, but the total matter in the universe remains constant."

“And then?"

"That's it."

"What can you derive from those little things?"

"The same way you can figure out an entire case from a bullet or a drop of blood, cosmic sociology is able to describe a complete picture of galactic and cosmic civilization from those two axioms. That's what science is like, Da Shi. The cornerstone of every discipline is quite simple."

 "So let's see you derive something."

...

"... The universe is big, but life is bigger! That's what the second axiom means. The amount of matter in the universe remains constant, but life grows exponentially. Exponentials are the devils of mathematics. If there's a microscopic bacterium in the ocean that divides once every half hour, its descendants will fill the entire ocean in the space of a few days, so long as there are sufficient nutrients. Don't let humanity and Trisolaris give you a false impression. These two civilizations are tiny, but they are only in their infancy. Once a civilization passes a certain technological threshold, the expansion of life through the universe is frightening. For instance, take humanity's present navigation speed. In a million years, Earth civilization could fill the galaxy. And a million years is a short time measured against the universe."

"So you're saying that, taking the long view, the entire universe might have that kind of... what are they calling it, a 'dead hand'?"

"No need for the long view. Right now the entire universe has been dealt that dead hand. Like Hines said, civilization may have started in the universe billions of years ago. Looking at the signs, the universe might be packed full already. Who knows how much empty space there is in the Milky Way or the universe, or how many resources are left?"

"But that's not right, is it? The universe looks empty. We haven't seen any other alien life apart from Trisolaris, right?"

"That's what we'll talk about next. Give me a cigarette."

Luo Ji groped about in the dark for a while before taking the cigarette from Shi Qiang's hand. When Luo Ji next spoke, Shi Qiang realized he had moved to a spot three or four meters away.

"We need to increase the distance to make it feel more like outer space," Luo Ji said.

Then he lit the cigarette by twisting its filter, and Shi Qiang lit one of his own. In the dark, two tiny red planets stood in distant opposition.

"Okay. To illustrate the problem, we now need to establish the most elementary model of cosmic civilization. These two balls of flame represent two civilized planets. The universe is made up of only these two planets, and apart from them there's nothing else. Erase all of our surroundings. Can you locate that feeling?"

"Yeah. That's an easy feeling to find in a dark place like this."

"Let's call these two civilized worlds your civilization and my civilization. They're separated by a great distance, say, a hundred light-years. You can detect that I exist, but you don't know any details. However, I'm completely ignorant of your presence."

"Right."

"Now we need to define two concepts, 'benevolence' and 'malice' between civilizations. These words themselves aren't very rigorous in a scientific context, so we've got to restrict their meaning. `Benevolence' means not taking the initiative to attack and eradicate other civilizations. 'Malice' is the opposite."

"That's a low bar for benevolence."

"Next, consider your options for dealing with me. Please remember that the axioms of cosmic civilization should be kept in mind throughout the process, as well as the distance scale and the environment of space."

"I could choose to communicate with you."

"If you do that, you should be aware of the price you'll pay: You'll have exposed your existence to me."

"Right. In the universe, that's no small thing."

"There are different degrees of exposure. The strongest form of exposure is when I know your precise interstellar coordinates. Next is when I know your general direction, and the weakest is when I only know of your existence. But even the weakest form of exposure makes it possible for me to search for you, because since you've detected my existence, I know that I'll be able to find you. It's only a matter of time from the standpoint of technological development."

"But my boy, I could still take the risk to talk to you. If you're malicious, then it's my bad luck. But if you're benevolent, then we could have further exchanges and ultimately be united into a benevolent civilization."

"Okay, Da Shi. Now we've come to the crux of it. Let's return to the axioms of cosmic civilization: Even if I'm a benevolent civilization, can I determine at the start of our communication whether or not you are also benevolent?"

"Of course not. That would violate the first axiom."

"So once I've received your message, what should I do?"

"Naturally, you ought to determine whether I'm benevolent or malicious. Malicious, and you eradicate me. Benevolent, and we can continue communicating."

The flame on Luo Ji's side rose up and moved back and forth. Evidently he had gotten up and was pacing.

"That's fine on Earth, but not out in the universe. So next we'll introduce an important new concept: the chain of suspicion."

"That's an odd term."

"The term is all I had at first. It wasn't explained to me. But, later, I was able to infer its meaning from the words themselves."

"Who didn't explain it?"

"... I'll tell you later. Let's continue. If you think I'm benevolent, that's not a reason to feel safe, because according to the first axiom, a benevolent civilization can't predict that any other civilization is benevolent. You don't know whether I think you're benevolent or malicious. Next, even if you know that I think you're benevolent, and I also know that you think I'm benevolent, I don't know what you think about what I think about what you're thinking about me. It's convoluted, isn't it? This is just the third level, but the logic goes on indefinitely."

"I get what you mean."

"That's the chain of suspicion. It's something that you don't see on Earth. Humanity's shared species, cultural similarities, interconnected ecosystem, and close distances means that, in this environment, the chain of suspicion will only extend a level or two before it's resolved through communication. But in space, the chain of suspicion can be very long. ...."

Shi Qiang took a drag on his cigarette, and his contemplative face emerged from the darkness for a moment.

"... In actual cosmic civilization, the biological differences between different groups might be as high as the kingdom level, and cultural differences are even further beyond our imagining. Add to this the vast distances between them, and you have chains of suspicion that are practically indestructible."

"That means that the outcome is the same, regardless of whether we're benevolent civilizations or malicious civilizations?"

"That's right. That's the most important aspect of the chain of suspicion. It's unrelated to the civilization's own morality and social structure. It's enough to think of every civilization as the points at the end of a chain. Regardless of whether civilizations are internally benevolent or malicious, when they enter the web formed by chains of suspicion, they're all identical."

"But if you're much weaker than I am, you're not a threat to me. So I could always communicate with you, right?"

"That won't work, either. Here we need to introduce a second important concept: the technological explosion. I didn't get a full explanation for this, either, but it was far easier to infer than the chain of suspicion. Human civilization has five thousand years of history, and life on Earth might be as much as a few billion years old. But modern technology was developed over the course of three hundred years. On the scale of the universe, that's not development. It's an explosion! The potential for technological leaps is the explosive buried within every civilization, and if it's lit by some internal or external factor, it goes off with a bang. On Earth it took three hundred years, but there's no reason why humanity should be the fastest of all cosmic civilizations. Maybe there are others whose technological explosions were even more sudden.

"I'm weaker than you, but once I've received your message and know of your existence, the chain of suspicion is established between us. If at any time I experience a technological explosion that suddenly puts me far ahead of you, then I'm stronger than you. On the scale of the universe, several hundred years is the snap of a finger. And it might be that my knowledge of your existence and the information I received from our communication was the perfect spark to set off that explosion. That means that even though I'm just a newborn or growing civilization, I'm still a big danger to you."

Shi Qiang watched Luo Ji's flame in the darkness as he thought for a few seconds, then looked at his own cigarette.

"So I have to keep quiet."

"Do you think that will work?"

They smoked. The balls of flame brightened and their faces emerged from the darkness like the gods of this simple universe, deep in thought. Shi Qiang said,

"No, it won't. If you're stronger than me, then since I was able to find you, one day you'll be able to find me. And then there will be a chain of suspicion between us. If you're weaker than me, you could experience a technological explosion at any time, and that would take us back to the first case. To sum up: one, letting you know I exist, and two, letting you continue to exist, are both dangerous to me and violate the first axiom."

"Da Shi, you've really got a clear mind."

"My brain can keep up with yours so far, but we're only getting started."

Luo Ji was silent in the dark for a long time. His face emerged in the weak light of the ball of flame two or three times before he said,

"Da Shi, this isn't a start. Our reasoning has already reached a conclusion."

"Conclusion? We haven't figured anything out! Where's the picture of cosmic civilization you promised?"

"If neither communication nor silence will work once you learn of my existence, you're left with just one option."

In the long silence that followed, the two flames went out. There was no wind, and the dark silence turned thick as asphalt, connecting sky and desert into a murky whole. At last Shi Qiang uttered one word in the darkness: "F***!"

"Extrapolate that option out to the billions upon billions of stars and hundreds of millions of civilizations, and there's your picture,"

Luo Ji said, nodding in the darkness.

"That's... that's really dark."

"The real universe is just that black."

Luo Ji waved a hand, feeling the darkness as if stroking velvet.

"The universe is a dark forest. Every civilization is an armed hunter stalking through the trees like a ghost, gently pushing aside branches that block the path and trying to tread without sound. Even breathing is done with care. The hunter has to be careful, because everywhere in the forest are stealthy hunters like him. If he finds other life—another hunter, an angel or a demon, a delicate infant or a tottering old man, a fairy or a demigod—there's only one thing he can do: open fire and eliminate them. In this forest, hell is other people; an eternal threat that any life that exposes its own existence will be swiftly wiped out. This is the picture of cosmic civilization. It's the explanation for the Fermi Paradox."

Shi Qiang lit another cigarette, if only to have a bit of light.

"But in this dark forest, there's a stupid child called humanity, who has built a bonfire and is standing beside it shouting, 'Here I am! Here I am!"' Luo Ji said.

"Has anyone heard it?"

"That's guaranteed. But those shouts alone can't be used to determine the child's location. Humanity has not yet transmitted information about the exact position of Earth and the Solar System into the universe. From the information that has been sent out, all that can be learned is the distance between Earth and Trisolaris, and their general heading in the Milky Way. The precise location of the two worlds is still a mystery. Since we're located in the wilderness of the periphery of the galaxy, we're a little safer."

"So what's the deal with the spell?"

...
Liu Cixin's science fiction is old-school and high-concept, inspired equally by Isaac Asimov's psychohistory and China's ancient history. This second volume grapples with the problem: how can you deal with an extermination force of overwhelming military superiority, almost perfect data intelligence but one which is hundreds of years away, past any planning horizon politicians, the military and the people are accustomed to?

As ever, his solutions are ingenious .. and implicit in the excerpt above.

In volume three, Death's End (April 2016), his ambitions seem to be set even higher.
