Book summary “Foundation and Earth”: summary

Introduction

You face a difficult choice when deciding the ultimate political future of humanity between decentralized sovereign states and a single galactic superorganism. Isaac Asimov presents this dilemma through the journey of Golan Trevize, who must locate the forgotten cradle of humanity known as Earth to resolve his decision.

Golan Trevize journeys across the Galaxy to find Earth and decide whether humanity's future lies in independent states or the planetary superorganism Galaxia.

You explore how historical records concerning Earth have vanished from galactic archives and libraries. The book investigates ancient abandoned worlds to reconstruct the path of human migration across the stars.

• Where is the legendary planet Earth located in the Galaxy?
• What happened to the ancient Spacer worlds that first left Earth?
• Can you trust a superorganism to protect human individuality?

1. The Quest and Comporellon

You explore how Trevize feels troubled by his own decision to choose Gaia as the future of humanity because he fears losing his individuality within a superorganism. Despite being recognized by Gaia for his unique capacity to make correct decisions on incomplete data, Trevize refuses to act merely as a black box.

Trevize questions Dom, the ancient of Gaia, about whether individual existence is expendable for the good of the planetary superorganism.

Historical documents and records concerning Earth have been deliberately removed or destroyed across the Galaxy, including within the Galactic Library at Trantor and on Gaia. Trevize observes that while ancient documents naturally decay over millennia, references to Earth have been purposely purged. Even on Gaia, preglobal records that likely documented the planet's early settlement by people from Earth are entirely missing.

Personnel of the Second Foundation recently discovered that material related to Earth was deliberately removed from the Galactic Library at Trantor in recent times.

Trevize leaves Gaia to find Earth, navigating bureaucratic entry stations and historical suppression on Comporellon.

Trevize's Dilemma

You find that Trevize's spaceship runs on the energy of the general gravitational field of the Galaxy and requires no refueling. Janov Pelorat falls in love with Bliss, a young woman who serves as an individual human component of the planetary consciousness of Gaia. Pelorat insists on joining Trevize's search for Earth because Bliss also wishes to accompany them on the mission.

Gaia replaces traditional written and digital records with a planetary memory distributed across human, animal, plant, and mineral components. Bliss explains to Trevize that when she needs esoteric historical data, she scans Gaia's total mind rather than consulting a physical library.

Arrival on Comporellon

You navigate strict immigration rules and microdetector screenings on Comporellon, which operates as an Associated Power. Worlds maintain orbital entry stations equipped with advanced microdetectors designed to check incoming travelers for disease-causing microorganisms.

• Insert the right hand into the microdetector device to automatically check for disease-transmitting microorganisms.
• Sign the color facsimile generated by the microdetector system.
• Present official identification papers for verification against planetary regulations.

A Comporellian official named A. Kendray boards the Far Star, conducts microdetector hand scans of the crew, discovers Bliss lacks identity papers, and insists on strict protocol until persuaded otherwise.

2. Leaving Comporellon

Skeptics and Legends

Vasil Deniador operates as a Skeptic on Comporellon, rejecting popular superstitions in favor of evidence-based primeval history. He states that while most Comporellians view Earth through fear and folklore, a Skeptic accepts only what reliable evidence forces. Comporellon suffers from a frustrated collective memory, believing it was once the leading world of the Galaxy.

Deniador notes that the population takes refuge in attacking and hating Skeptics who dismiss their legends.

• The general public constantly scolds and denounces the Skeptics.
• Control over essential technology and university faculties protects them from physical persecution.

According to primeval history, human expansion occurred in waves. The first robot-using settlers died out or faced punishment. These settlers developed high technology and longevity using robots, but societies dependent on robots grew decadent and perished. This led to a second wave of settlers who prohibited robots.

Deniador discusses the legendary Spacer worlds, whose inhabitants lived for centuries and refused entry to short-lived ancestors.

• There were fifty such Spacer planets in the legends.
• These worlds went twenty thousand years without dealings with outside societies.

Janov Pelorat describes a historical project by Livian historian Humbal Yariff. Yariff posited that worlds closer to the point of origin were settled earlier than distant ones. By mapping networks of planets sharing the same age in millennia, concentric spherical surfaces would theoretically pinpoint Earth.

Yariff's project failed due to specific obstacles:

• Worlds exaggerated their ages to appear older.
• Carbon-14 data on ancient timber was withheld due to a lack of cooperation.
• Younger settlement waves centered around Trantor obscured the original pattern.

The Three Uniquities

Pelorat and Trevize synthesize the physical markers of Earth into three specific clues. A definitive identification of Earth relies on confirming these three unique characteristics together.

• A radioactive crust caused by historic punishment.
• A large satellite measuring between three thousand and three thousand five hundred kilometers in diameter.
• A system of three exceptionally wide concentric planetary rings mentioned in an ancient poem.

Encounters with Skeptics reveal the legends of the first wave of Spacer worlds and the uniquities required to identify Earth.

Trevize programs the ship's computer to roll back the map memory by twenty thousand years to locate these ancient coordinates. Stars and planets orbit the Galactic Center at different speeds and inclinations, which causes coordinate data to drift.

The Far Star accelerates to a speed of 0.1 c while plunging outward between the outer planets of the Comporellian system past a distance of 1.5 billion kilometers from the sun. Practical interstellar flight speed is capped at this limit of thirty thousand kilometers per second to prevent destructive collisions with cosmic ray particles and stray atoms.

3. The Forbidden Worlds

Explorations of Aurora, Solaria, and Melpomenia expose the dangerous extremes of planetary isolation and mutant robot technology.

You must determine a massive local sun's distance with extreme precision using parallactic shifts before executing a safe Jump. Trevize performs this calculation inside the pilot-room of the Far Star while preparing to approach the Forbidden World. Bliss explains that human-settled worlds lack true ecosystems and undergo unterraforming when abandoned.

Aurora and Wild Packs

Trevize arms himself before exploring an unknown planet, carrying both a lethal blaster and a non-lethal neuronic whip. When Trevize sets foot on the deserted world, he carries his navy-issue blaster and neuronic whip, noting that the surface gravity is about ninety-one percent that of Terminus. Domestic animals multiply into packs in the prolonged absence of human oversight.

Trevize is cornered in a tree by a growing pack of twenty-three lean, rangy dogs that treat him as prey and attempt to attack him when he steps away from the ship. A neuronic whip drives away hostile animals better than a blaster by causing pain that triggers mutual fear. When Trevize shoots one dog with the neuronic whip on low power, the animal screams, causing the rest of the pack to squeal and run away.

Pelorat deciphers archaic lettering that reads Planet Aurora in ancient ruins. When Pelorat approaches the humanoid metal object in the ruins, it crumbles into rust, its eyes glowing faintly as it attempts to speak.

Solaria and Hermaphrodites

Solarians rely on robots and preserve an archaic language over millennia of isolation. Sarton Bander tells Trevize to address him simply as Bander and states that he is neither male nor female, but whole. Bander causes Trevize's weapons to rise from their holsters, inspects them, and drains their energy units while holding the travelers immobilized.

Solarians evolved beyond biological gender by modifying their genes underground to become whole human beings. Bander notes that its estate spans over forty thousand square kilometers, and the entire planet of Solaria houses only about twelve hundred people. Solarians use transducer-lobes in their brains to power their civilization without mechanical devices.

Bander demonstrates this technology by making Trevize's weapons float in the air and by illuminating room walls simply through hand gestures and mental transduction. Bliss accidentally killed Bander when she tried to use a mental blocking maneuver to stop him from assassinating her and her companions. Fallom is a fourteen-year-old hermaphroditic child found hiding in an underground room behind an inactive robot named Jemby.

Four Guardian Robots confronted Trevize, Pelorat, and Bliss near their spaceship after Bander's death. Fallom would not be recognized as a Successor and faced destruction due to an excess of children on the planet. Bliss successfully studied the tight mental programming of the Guardian Robot and deactivated it when it attempted to seize Fallom.

The Far Star escapes Solaria just as a second Solarian ship lands and others approach, avoiding being overwhelmed by robots. Pelorat tells Trevize that his visit to Solaria convinced him that Galaxia is the correct path for humanity because individual Isolates can descend into horrible social extremes.

Melpomenia and Moss

Trevize analyzes a massive gas giant in the third star system that is nearly two thousand times as massive as a habitable planet and practically a dwarf star. Trevize realizes the third target planet has almost no craters, proving it sustained an atmosphere, oceans, and life until recently.

• Spot potential cities from orbit using radar-mapping and visual analysis.
• Differentiate between large sprawling commercial centers and smaller administrative cities containing open space.
• Target the smaller administrative city for landing to locate planetary museums, libraries, archives, and universities.

Trevize and Pelorat find a crumbling three-story structure where Pelorat decodes fifty names, with Aurora listed first and Solaria last. The dominant life form on Melpomenia is a bright green moss that secretes acid to break down carbonate rock. Trevize notices green fuzz growing around the edges of their space suit face-plates, which feed on the carbon dioxide leaking from their breath.

• Keep the airlock closed and spray the outer rim with a low-intensity heat beam to destroy organic residue.
• Pumping out planetary air from the lock while keeping ship air sealed.
• Systematically pass a heat beam over space suits, face-plates, and boots to eliminate spores.
• Undress in the lock area and apply ultraviolet radiation to all garments and ship surfaces.

While Trevize prepares to embark on a lengthy search of all forty-seven remaining Spacer worlds, Pelorat interrupts to state that he has the answer regarding Earth.

4. New Earth and the Search Ends

The travelers discover New Earth, confirm Earth's radioactive state, and meet R. Daneel Olivaw on the moon.

The Center of the Worlds

While millions of worlds of the second expansion were settled chaotically over 20000 years, the 50 Spacer worlds of the first expansion were settled over a few centuries. Their known coordinates can be adjusted for stellar motions and used to calculate the center of the sphere, which leads directly to the region of Earth's sun.

Trevize inputs 50 sets of coordinates into the ship's computer and successfully identifies Aurora based on its known characteristics, confirming the validity of coordinate conventions. The calculated center points to a yellow-white G-2 star designated Alpha on the Galactic map. Closer inspection reveals it is actually a binary system with a smaller orange companion star.

The binary system features an 1.4 million kilometers diameter of Alpha, 1.02 times Terminus sun mass, 6000 absolute surface temperature, under 30 days slow rotation, 80 years orbital period of the binary companion, four-fifths mass of the smaller star relative to the brighter one, and 1 parsec distance between Alpha and Earth's sun.

New Earth Festival

With an average separation between the two stars of 3.5 billion kilometers and 1.7 billion kilometers separation at periastron, stable planets must orbit within 200 million kilometers. Following a systematic grid search, the travelers locate a sizable island on the planet Alpha Centauri.

The island measures two hundred and fifty kilometers long, sixty-five kilometers wide, fifteen thousand square kilometers in area, and holds more than a score and five thousand population on the island. A young woman named Hiroko correctly identifies the backward-printed letter F on the ship's hull as an archaic form from about two thousand years ago.

Monolee explains that after centuries of conflict between Spacers and Settlers, Earth's huge underground cities crumbled as radioactivity intensified. Eighty Standard Years represents the orbital period of the Companion star around the Alpha sun. Hiroko breaks down in tears and rushes to Trevize's quarters at night to warn them to escape immediately because Trevize has been infected and the community plans to kill them all.

• Leave the planet immediately in the dark before the fishing fleet returns.
• Take the child and the flute away from Alpha to ensure survival.

The Moon Base

Trevize, Pelorat, and Bliss travel towards an unmapped star that is a virtual twin of Alpha, maintaining 1/10 of a parsec distance from the sun after the Jump. They approach within 10 billion kilometers of the sun when observing the gas giants, and 1.5 billion kilometers from Earth when observing it without being stopped. The computer detects secondary radiations from gamma rays, rendering Earth in false color and proving it is intensely radioactive.

Trevize deduces that as Earth grew radioactive, secrets were moved to its thirty-five-hundred-kilometer-diameter moon. The mysterious being on the moon is revealed to be the ancient robot R. Daneel Olivaw, who has survived for twenty thousand years. Daneel's present brain has endured six hundred years out of five times the positronic brain has been replaced.

Daneel explains the Zeroth Law, stating that a robot may not injure humanity or allow humanity to come to harm. Daneel engineered the founding of Gaia and supported psychohistory, which was developed five centuries ago. Daneel plans to merge his failing positronic brain with the Solarian child Fallom to secure the three or four centuries lifespan required for the construction of Galaxia. Trevize confirms his decision in favor of Galaxia, arguing that humanity must unite to defend against potential hostile intelligence from other galaxies.
