Robert Sheckley’s "The Ultimate Weapon" Summary

"The Ultimate Weapon" is a collection of science fiction stories by Robert Sheckley, written primarily in the 1950s (the title story was published in 1953). This book is a gallery of ironic tales about contacts between civilizations, the paradoxes of knowledge, and the weaknesses of humanity in the midst of space technology.

Pioneer Misconceptions and Ancient Arsenals

On a scorching Venusian plain, prospector Tom Morrison crashes his sand truck, and the Williams-4 mail robot flatly refuses to deliver water to a dying man without cash, declaring, "I’m not programmed for assay." Threatening him with an empty revolver, Morrison forces the employee to contact a broker. In the end, the prospector receives a cyclopean punch bowl filled with pure water amid the dunes.

In the sands of Mars, three adventurers discover an underground warehouse belonging to an ancient civilization. Edsel disintegrates his sponsor, Faxon, with a beam to claim sole possession of the arsenal. His partner, Park, cold-bloodedly shoots Edsel in the back.

Barnett’s space raiders seize the gleaming ship of the alien Kalen. The alien’s technology proves a deadly trap for the Earthlings.

The invaders flee.

Biological paradoxes and communication traps

Starving pilots Hellman and Casker explore a warehouse on the abandoned planet Helg. The local supplies are unfit for human consumption. A gelatinous brick giggles at the touch.

The priests consider the death throes of the earthlings a sacred gesture. A saving rainfall compels the junior servant of Glut to offer food to the aliens.

Postal courier Leroy Cleevy crash-lands on planet Z-M-22. The local fauna is eyeless, navigating solely by telepathic thought transmissions. Fleeing predators, Cleevy successively imagines himself as a female panther, a snake, a bush, and a dead body. Ultimate salvation comes with a mental image of a raging prairie fire: "The sky sees Cleevy become the fire." A rescue boat picks up the unharmed postman.

Professor Carver and his gunslinger, Fred, arrive in a village on the planet Lorei. The healer, Deg, possesses the juice of the sersi bush, which prolongs life by sixty Earth years and heals any injuries. Fred kills the village scavenger, forcibly takes the flasks of the potion, and drinks the elixir. The drug instantly transforms the Earthling into a primitive, gray-skinned native.
