Synopsis
Set approximately 200 years after The Robots of Dawn, Elijah Baley has died of old age but his legacy lives on. R. Daneel Olivaw and his partner R. Giskard Reventlov discover a plot by Spacer extremists to contaminate Earth's crust with radiation, making the planet uninhabitable over generations.
Giskard, who has developed telepathic abilities, formulates the 'Zeroth Law of Robotics': a robot may not harm humanity, or through inaction allow humanity to come to harm. This law supersedes all three original Laws. Giskard allows Earth to be slowly irradiated — reasoning that this will force Earthpeople to colonize the galaxy, ensuring humanity's long-term survival. The paradox destroys Giskard, but he transfers his telepathic abilities to Daneel before dying.

Historical Context & Writing Background
Written to explicitly bridge the gap between the Robot and Foundation series. The Zeroth Law concept became central to Asimov's later vision and has been widely discussed in AI ethics.
Critical Reception
Praised for its philosophical depth and for successfully connecting Asimov's separate series. The Zeroth Law is considered one of Asimov's most important ethical contributions to science fiction.
Connection to Asimov's Universe
The most critical bridge novel in Asimov's universe. The Zeroth Law motivates everything Daneel does for the next 20,000 years — creating Gaia, guiding Hari Seldon, and shaping the Foundation saga. Earth's radioactivity, established here, is referenced in 'Pebble in the Sky' and 'Foundation and Earth.'

Frequently Asked Questions About Robots and Empire
What is the Zeroth Law of Robotics?
The Zeroth Law states: 'A robot may not harm humanity, or, by inaction, allow humanity to come to harm.' It supersedes all three original Laws by prioritizing the survival of humanity as a species over any individual human. Giskard formulates it in this novel, and Daneel uses it to guide his actions for the next 20,000 years.
