Editing The Santaroga Barrier (section)

==Plot summary==
A [[psychologist]], Gilbert Dasein, is hired by corporate interests to investigate Santaroga, a southern California{{sfn|Herbert|1982|p=23|ps=: The book never states "southern California" but describes the location of Santaroga as "[[Porterville, California|Porterville]] was 25 miles away, ten miles outside the valley on the road he had taken. The other direction led over a winding, twisting mountain road some forty miles before connecting with [[U.S. Route 395 in California|highway 395]]."}} town in a valley where marketing seems totally ineffective: outside businesses are allowed in, but wither quickly for lack of business. Santarogans aren't hostile toward the enterprises, they just won't shop there. Nor are they [[xenophobia|xenophobic]]; they instead appear maddeningly self-satisfied with their quaint, local lifestyle. Adding an element of danger, the last few psychologists sent in have all died in accidents that are (seemingly) perfectly plausible.  Complicating matters further still, the psychologist's college girlfriend, Jenny, has returned to Santaroga, her hometown.

With this in mind, Dasein cautiously enters the town and quickly learns of 'Jaspers', an additive in the food and drink commonly ingested in Santaroga that seems to imbue the consumer with greater health and an expanded mind. Within the Santarogan community, Jaspers was described as "Consciousness Fuel" which opened a person's eyes and ears, and turned on their minds.{{sfn|Herbert|1982|p=106}} Those who consume it don't become psychic; instead, they're simply far more lucid than the average citizen of the U.S., although there are numerous hints at a [[Group mind (science fiction)|group mind]] operating at a subconscious level.<ref name="gkw" /> Their newspapers are vaguely subversive with their folksy, enlightened commentary on world affairs; their dinner conversations knowledgeably reference great theories of psychology, politics, and cognitive science.

Soon, Dasein is having narrow misses with perfectly plausible<ref name="Bio">Herbert, Brian (2003) ''Dreamer of Dune: The Biography of Frank Herbert'' Tor, New York, pages 216-217, {{ISBN|0-7653-0646-8}}</ref> accidents: a clerk adjusting valves in the kitchen floods Dasein's hotel room with gas;{{sfn|Herbert|1982|pp=26-29}} Dasein trips on some loose carpeting, stumbles, falls through a stairwell railing and would have plunged three floors but was caught and saved by a Santarogan{{sfn|Herbert|1982|pp=63-64}} (although the incident with the carpeting and fall through the stairwell railing appeared to be a fluke accident, Dasein later realizes it could have been part of a carefully laid trap{{sfn|Herbert|1982|p=76}}); a boy playing with a bow and arrow releases it, grazing Dasein's neck; the lift under his car in a garage collapses; a waitress in a diner accidentally uses insecticide rather than sugar for his coffee. Knowing that Jaspers creates exceptionally perceptive, penetrating individual minds, Dasein realizes that he has offended a communal [[Id, ego, and super-ego|id]] that feels threatened by him. As Jenny tries to convince him to settle down with her there, he wonders whether he'll live long enough to decide.
