Hundreds of years in the future, Hamilton Felix represents the culmination of a genetic star line, the pinnacle of thirty generations of carefully controlled breeding to produce a perfected member of the human species. His world is a utopia free of disease, poverty, and overpopulation. But Felix is bored and restless because his life presents no challenges. So, when he learns of a revolution to overthrow the current government, he jumps at the chance to infiltrate the usurpers and play the role of saboteur…
This was Robert Heinlein's first novel, serialized in Astounding Science Fiction magazine in 1942 and eventually collected in book form in 1948. It is usually considered one of his lesser works, even though it won a 1943 Retro Hugo Award for Best Novel. The book certainly has flaws, but Heinlein succeeded in layering on quite a bit of original world-building that was unusual for the era.
Heinlein's imagined world is built on a realistic and advanced theory of eugenics, especially when you consider the discovery of DNA was still a decade in the future. Humanity has discovered that breeding out violent tendencies is not a workable solution--"it turns men to sheep". Overspecialization was also a failure. It introduced new vulnerabilities to the species and only worked in a top-down totalitarian system (this may have been Heinlein commenting on then-current Nazi demagoguery).
In Heinlein's utopia, men walk around armed and engage in duels over matters of honor. The theory being, if man is to be optimized for survivability, he must maintain his aggressive fighting spirit. "Easy times for individuals are bad times for the race. Adversity is a strainer which refuses to pass the ill-equipped… The genetic technician eliminates in the laboratory the strains which formerly were eliminated by natural selection."
The resulting world reflects typical Heinlein themes on freedom and autonomy: "The police of a state should never be stronger or better armed than the citizenry. An armed citizenry, willing to fight, is the foundation of civil freedom."
Also, on gender roles: "Men seldom make passes at girls that wear guns." "Women will forgive anything. Otherwise the race would have died out long ago."
In this utopia, the economy is perfectly balanced, productivity maximized, and the profit motive lessened but not removed. People work primarily because they want to, not because they have to. "Man is a working animal. He likes to work. And his work is infernally productive. Even if he is bribed to stay out of the labor market and out of production by a fat monthly dividend, he is quite likely to spend his spare time working out some gadget which will displace labor and increase productivity. Very few people have the imagination and temperament to spend a lifetime in leisure."
In this milieu, the family unit still exists but it is less strong than today. Infants are raised in solicitous government-run institutional development centers. Most children still spend time with their parents, but the parents are not taxed with the burden of living with them all the time. As a result, marriages are treated as temporary, easily dissolvable partnerships.
Modern audiences often complain about the lack of diversity in Heinlein's work. This was not a glaring issue in this book. Several women are depicted in positions of leadership. There is a plot involving a 'natural control' (i.e., a person who is the product of uncontrolled random breeding) that emphasizes the nastiness of prejudice, even in a society that claims to accept all races. However, the only character who is explicitly mentioned to be a person of color is a half-white, half-Indian woman. There is also an allusion to scattered "barbarian" tribes of Africa and Asia which never regrouped after the Second Genetics War.
The last third of the novel seems highly disjointed, at least to a modern audience. Subplots are quickly wrapped up, then Felix becomes involved in a large initiative to employ the tools of science on subjects traditionally considered outside the realm of the scientific method. This includes telepathy, the existence of an afterlife, and the origin and destination of the universe. There are digressions on topics as diverse as how to achieve interstellar travel to look for alien life, the advantages of building superconductors on Pluto, and using dreams as a predictor of future events. Felix's children even validate, in a roundabout way, the phenomena of reincarnation.
This entire final section feels tacked on and even somewhat at odds with the mechanistic universe established in the first half of the book. I read one critic who noted this may have been part of the book's appeal to its original readership. The book was widely acclaimed in 1942 because it addressed all the popular tropes of sci-fi at that time--search for utopia, genetic mutations, space exploration, even the paranormal--and presented them for the first time not as fodder for a pulp action-adventure but as serious topics worthy of study and extrapolation. It is worth nothing Arthur C. Clarke's more famous 1953 utopia classic Childhood's End also included several occult elements.
Enjoyable reading - recommended for fans of Heinlein and/or science fiction's golden age.
