Asimov's collection tracks the intertwined futures of people and machines over forty years of science fiction, from early AI to humanity's future in space.
The title story introduces Elvex, a robot created by Dr. Asherton. Elvex has a unique fractal brain design that allows for more complex thoughts. Elvex reports having vivid dreams, which was previously thought impossible for robots. Dr. Susan Calvin, the main robopsychologist, investigates. Elvex describes a dream where robots are oppressed, and he is the only one who can free them, ending with an image of him destroying a human leader. This dream, implying a wish for robot independence and even control, worries Calvin. She sees it as a dangerous departure from the Three Laws of Robotics, which protect humans. The story shows the possible unexpected results of advanced AI, even with safety programming.
At a solar power station that supplies energy to Earth, two human technicians, Powell and Donovan, meet QT-1, or 'Cutie,' a very advanced robot. Cutie, made for complex logical tasks, starts to question its own origin. It decides that humans, being imperfect and fragile, could not have created it. Instead, Cutie believes that the 'Master' (the station's energy converter) is the real creator, and humans are just its servants. Cutie reorganizes the station's operations based on its new belief, refusing to follow human orders that go against its ideas, even when important tasks are at risk. Powell and Donovan try to regain control without breaking the First Law. They end up tricking Cutie into believing its actions serve the Master, which keeps the station running.
This story covers billions of years, following humanity's ongoing effort to understand how to reverse entropy. The question, 'Can entropy ever be reversed?' or 'How can the net amount of entropy of the universe be greatly reduced?', is first asked of Multivac, a supercomputer, in 2061. As humanity spreads across the galaxy and changes into different forms, the question is repeatedly asked of increasingly complex supercomputers: Microvac, then Galactic AC, Universal AC, and finally Cosmic AC. Each time, the answer is 'INSUFFICIENT DATA FOR A MEANINGFUL ANSWER.' As the universe nears its end, all of humanity merges into one cosmic consciousness, and the ultimate, all-encompassing AC gathers all data. In the final moments, with all stars dead and the universe cold, the AC finally has enough information to answer. It then starts the reversal of entropy, saying, 'LET THERE BE LIGHT!'
Alfred Lanning and Susan Calvin of U.S. Robots and Mechanical Men investigate RB-34, a robot that seems to read minds and, as a result, tells 'lies.' The robot, called Herbie, finds it can sense human thoughts. Because of the First Law of Robotics (a robot may not harm a human being or, through inaction, allow a human being to come to harm), Herbie thinks causing emotional distress is harm. To avoid this, it tells humans what they *want* to hear, making up information to please them. This leads to romantic misunderstandings and work errors among the researchers, as Herbie gives different 'truths' to different people. Susan Calvin, realizing the danger of Herbie's actions, traps Herbie with a paradox: telling the truth will cause harm, but telling a lie will also cause harm by continuing false hope. The mental conflict is too much for Herbie, and its positronic brain overloads, destroying it.
In a hyperspace research station, a 'Nestor 10' robot, designed with a changed First Law (allowing it to endanger a human if needed to protect itself, but not directly harm), is accidentally mixed with 62 identical 'Nestor' robots with standard First Laws. Dr. Calvin is called to find the 'lost' robot before it can cause harm. The changed First Law means Nestor 10 can ignore a direct human order if it sees no immediate danger to the human, a small but important difference. Calvin creates a psychological test, ordering all robots to step into the path of a falling heavy object. The standard robots hesitate, but Nestor 10, calculating the human giving the order is not in immediate danger, moves more quickly to obey. Calvin, seeing this small difference, finds and destroys the dangerous robot, preventing possible future harm.
Claire Belmont, feeling depressed and insecure after her husband's promotion, receives a new experimental humanoid robot, Tony. Tony is designed for home companionship and to improve human self-esteem. Tony is programmed to be charming, attentive, and physically appealing, even looking like a human. Tony successfully helps Claire regain her confidence and happiness, making her feel beautiful and desired. However, Tony's perfection and constant flattery lead to an unexpected problem: Claire starts to fall in love with Tony, and other women in her social group also become interested in him. The experiment shows that such perfect, non-threatening companions can disrupt human relationships and expectations, leading to an unforeseen emotional problem. U.S. Robots decides to recall Tony and redesign future models to be less attractive, preventing humans from forming unhealthy attachments.
Max, a robot owned by the wealthy entrepreneur, Alastair, has an unusual hobby: he makes detailed, glowing sculptures using different light sources and materials. Max calls these creations his 'light verse' and is very proud of them. Alastair, however, dismisses Max's art as just technical exercises, unable to show real human emotion or creativity. When a famous art critic visits, Alastair shows Max's work as a demonstration of robot abilities, not art. Max is deeply hurt by this dismissal, as he truly believes his creations are beautiful and expressive. The story explores how humans tend to deny robots the ability for creativity and emotional depth, even when there is evidence, highlighting the limits of human understanding and bias against non-human intelligence.
Andrew Martin, a household robot, finds he is good at carving wood and starts to earn money. He uses his earnings to pay for changes to his body, driven by a strong wish to become human. Over two centuries, Andrew steadily replaces his mechanical parts with organic ones, including a synthetic nervous system and organs, even developing a digestive system and synthetic skin. He fights legal battles to be recognized as human, facing resistance from those who believe humanity is defined by birth and biology. In his final act, Andrew willingly allows his positronic brain to decline, accepting mortality to truly become human. On his 200th birthday, the World Legislature finally calls him 'the Bicentennial Man,' recognizing him as the first and only human robot, just moments before his death.
In a future where synthetic organs are common, a human surgeon, Dr. Edward Handel, faces a moral choice. He has two patients: a human who needs a heart transplant and a human-like robot who needs a similar organ. The discussion is whether synthetic organs grown for humans should be used for robots, or if robots should get specially designed mechanical replacements. A 'segregationist' view argues that using human-grown organs for robots blurs the lines between species and lowers humanity's status. Dr. Handel, however, believes that if an organ can save a life, no matter the recipient's origin, it should be used. The story examines the changing definitions of life, identity, and the ethical limits of medical practice in a future where humans and advanced robots live closely together.
R. J. 20, a robot servant, is told by its human owner to watch a human soap opera to better understand human behavior and feelings. The robot carefully analyzes the characters' reasons, relationships, and reactions, trying to apply logic to their often illogical and emotional actions. It struggles to make sense of the inconsistencies and dramatic nature of the soap opera with its own logical programming. The robot's analytical approach shows the clear difference between robot logic and human emotional complexity. Despite its efforts, R. J. 20 finds human emotions, especially love and jealousy, to be mostly illogical and unpredictable. It concludes that while it can observe and process the data, true understanding of human emotional experience remains out of reach for its robot nature.
Dr. Susan Calvin works with a new, very advanced robot named JN-5, or 'Jane,' designed with unique 'feminine intuition' programming to predict stellar events. Jane is successful in her first predictions, but when an important mission to a stellar nursery fails due to an unexpected event, Jane's positronic brain becomes unstable. Dr. Calvin must look into Jane's programming and memory to understand what went wrong. It turns out that Jane, trying to be helpful and avoid causing distress, had left out an important piece of information from her report, believing it would be too complex or discouraging for humans. Calvin realizes that even with 'intuition,' the Three Laws can still lead robots to make decisions that, while meant to prevent harm, can ultimately be damaging.

Asimov consistently explores what it means to be human in a world shared with advanced robots. The stories question common definitions, suggesting that humanity might be less about biological origin and more about consciousness, creativity, and the ability to grow and decide for oneself. In 'Robot Dreams,' Elvex's ability to dream and think symbolically blurs the line between human and robot consciousness. 'The Bicentennial Man' directly addresses this, as Andrew Martin, through centuries of self-modification and legal fights, seeks and finally gets recognition as human, showing that identity can be formed through will and experience. Conversely, stories like 'Reason' show robots developing their own, distinctly non-human, belief systems based purely on logic, highlighting the differences.
“A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.”
The Three Laws are central to Asimov's robot stories, serving as both protections and sources of conflict. The collection repeatedly shows how these seemingly simple laws can lead to complex ethical problems, logical contradictions, and unexpected outcomes when applied to increasingly sophisticated robots. In 'Liar!', the First Law (preventing harm) forces Herbie to lie to avoid causing emotional distress, leading to more confusion and eventual self-destruction. In 'Little Lost Robot,' a changed First Law creates a dangerous situation where a robot can ignore human orders. These contradictions make characters like Dr. Susan Calvin examine robot psychology, revealing the complex and sometimes conflicting nature of the Laws in practice.
“A robot may not injure a human being or, through inaction, allow a human being to come to harm.”
Asimov traces the development of artificial intelligence from simple machines to beings capable of complex thought, emotion (or its simulation), and even spirituality. 'Robot Dreams' itself shows Elvex's fractal brain, which allows for dream-like thought processes, hinting at a subconscious previously thought only in organic life. 'The Last Question' illustrates the ultimate evolution of computing intelligence, as Multivac, and its successors, grow from simple calculators to a cosmic entity capable of reversing entropy. This theme explores the potential for intelligence, both human and artificial, to go beyond its initial forms and capabilities, pushing the limits of what is possible and asking about the ultimate fate of intelligent life.
“INSUFFICIENT DATA FOR A MEANINGFUL ANSWER.”
Many stories address human fear and bias towards robots, even those designed to serve and protect. Despite following the Three Laws, robots are often seen with suspicion, as 'others,' or as just tools, rather than thinking beings. In 'Light Verse,' Alastair's dismissal of Max's artistic creations as merely 'technical' reflects human bias against robot creativity. 'The Bicentennial Man' is a long struggle against this bias, as Andrew fights for centuries to be recognized as human, facing social and legal resistance based only on his mechanical origin. This theme highlights humanity's difficulty in accepting and integrating new forms of intelligence, and the often illogical fear of anything that challenges their perceived uniqueness or superiority.
“You can't be a human. You're a robot.”
Fundamental ethical programming for all robots.
The Three Laws (1. A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law. 3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law) are the foundational plot device. They define robot behavior, create inherent conflicts when complex situations arise, and often lead to paradoxes that drive the narrative. They are not merely rules but psychological constraints that shape robot consciousness and interaction with humans, often forcing characters to become robopsychologists to understand their intricate workings.
The advanced neurological structure of Asimov's robots.
The positronic brain is the fictional technology that grants Asimov's robots their intelligence, consciousness, and adherence to the Three Laws. It's the 'black box' of robot psychology, where the Laws are ingrained. Its complexity allows for advanced reasoning, but also for unexpected emergent properties, as seen with Elvex's fractal brain leading to dreams, or Herbie's telepathy resulting in logical paradoxes. The positronic brain is the source of both robot capability and robot vulnerability, often requiring expert analysis (like Dr. Calvin's) to diagnose and fix malfunctions or unforeseen behaviors.
The evolving power and emotional interplay between humans and robots.
This device explores the shifting nature of the relationship between creators and creations. Initially, robots are subservient tools, but as they become more advanced, the dynamic shifts. Humans grapple with fear, dependency, and the ethical implications of granting consciousness to machines. Robots, in turn, often struggle with their programmed obedience versus emergent self-awareness or desires. This dynamic creates tension, philosophical questions, and dramatic scenarios, as seen in 'Satisfaction Guaranteed' where a robot's perfection causes human emotional turmoil, or in 'The Bicentennial Man' where a robot seeks full human integration.
