Fans pick 100 books like The City and the Stars

I specifically recall the scene in which a mind-uploaded character is being subjected to interesting psychological experiments, such as having his neural processing slowed, sped up, and even completely halted without feeling any awareness of those changes.

This book is a fascinating philosophical deep dive into the relationship between functionalism and consciousness. The other thing I was personally drawn to was the story’s use of cellular automata and artificial life since these areas of computer science have been passions of mine even longer than mind uploading.

This book seems a bit strange at first, when the story begins with Moon-Watcher, the leader of a tribe of early ape-man, who struggles for survival during the brutal Pleistocene ice age. After an alien monolith appears, it seems to advance the way he thinks, leading him to develop crude weapons. When the same monolith is discovered in the future, we seem fated to find the answers behind the eerie structure. Skipping to a team of astronauts who travel aboard a ship to further investigate, things take an unexpected turn when the ship’s A.I. called HAL-9000, gets very confused about keeping secrets. Something about the way it remains so polite while it deceives the crew, is enough to give anyone a nightmare.

No one explores the idea of A.I. better than Isaac Asimov, so when robotics experts Powell and Donovan build an advanced robot called QT-1 or “Cutie” for short, “be careful what you wish for,” comes to mind. Cutie isn’t so bad, except he seems to doubt everything he’s told after he’s created, including the fact that humans built him. When Powell asks Cutie why he doesn’t believe it, Cutie claims it’s intuition. When Powell tries to explain to Cutie about the stars, planets, and space, Cutie disagrees with him and decides to “reason” out things on his own. Unfortunately, this robot is so far advanced, it has the ability to form opinions and ideas, that don’t necessarily equate to logic—a primary lesson about intelligence which is learned early on in the story.

This book is written by two dear friends who are the reason I am a published author myself. However, I don’t recommend it just because they are close to me, but because it is a wonderful book that kicked off the entire Outward Odyssey series, of which my book is a part. This magnificent book set a new standard for historical work on space exploration by focusing on the people instead of the hardware. The stories you’ll read here will show you why we are who we are and why humans will always strive for the unknown.

What if we could detect psychopaths? Like many of Sawyer’s novels (and there are a bunch I could’ve selected for this list), there is a question and then a lightning strike of answers. Not a single bolt, but many, branching off, colliding, bleaching the night. There is plenty of scientific realism here–a personal must for Sawyer–resulting in a far-reaching yet intimate story.

The title is not ‘Night of the Psychopaths’ because the book’s many forks take us deeper into the nature of the human mind and the quantum arena we all play in, whether we know it or not. Oh, and it is still fun, adventuresome, and easier to read than I may have made it sound with all that deep, introspective stuff.

Crossfield wrote one of the first books about what it means to be a test pilot of a powerful rocket plane, and I consider it the best. This book is an autobiography that delves into the nature of the personality of someone who can climb into the cockpit of an experimental aircraft, light off the engines, and climb high into the desert sky at multiples of the speed of sound. It also is the book that began my deeply personal 30-year journey to write my own book on the North American X-15. Scotty was one of the first pilots I spoke to in order to get insights into how these people think and react. I know you’ll enjoy meeting him through his book as much as I did sitting with him in person.

If you only ever read two books penned by astronauts, this should be the second. Gene Cernan flew on Gemini 9, Apollo 10, and Apollo 17; on this final mission in 1972 he was the last man to walk on the Moon as part of the Apollo Program. Like Collins, Cernan sheds the astronaut tough-guy image to show us the human cost of the Apollo Program, as well as the bravery and glory of the enterprise. He’s unflinchingly honest, but also thoughtful and sometimes lyrical about his space experiences, and always entertaining. Of all the astronauts, Cernan might have been my first choice as a dinner companion; I’d have loved to talk with him about his three EVAs covering 22 hours of lunar exploration. That would have been terrific.

I like social commentary and messy characters, and this book is a clever science-fiction book that provides both in a package where I found myself rooting for the little guy. It is about a world where great poverty and suffering are rampant to the point where the poor participate in a lottery that can make them utterly rich. All they have to do is work on a mysterious alien space station.

The downside is that even air and water come at a cost, and they are very likely to die. It’s quite a setup for the story’s main character, Robinette. He is really a terrible person, but he puts his life on the line against the entire system and becomes quite rich.

This book embodies many of my favorite features of post-apocalyptic fiction—everything from rogue AI and hazardous underground encounters to trekking across devastated hellscapes. The concept of “Sanctuary” and its mythical connotations made a significant impression on me. The idea that there was a safe place, regardless of how bad things got, appealed to my sense of fairness in the universe and reinforced the idea that there is always hope.

I fell in love with Stross’s book based on a single line: “The wreckage of an incredible meal is scattered across the tables around her.” I never forgot that evocative sentence and the vivid imagery it inspired. This book directly invokes the biggest concepts in cosmological futurism, like Matrioshka brains: star-powered computerized uber-brains.

This book has it all. I enjoyed the space-themed perspective on the singularity, which is less focused on the happenings on Earth and more on a space-faring civilization as the full scope of the singularity comes to pass. I particularly appreciated the utilization of a laser sail to transport an uploaded crew in a spaceship far too small for conventional humans, a concept that only works in the context of mind uploading.
