Robert A. Heinlein

Robert Anson Heinlein was an American science fiction author, aeronautical engineer, and naval officer. Sometimes called the "dean of science fiction writers", he was among the first to emphasize scientific accuracy in his fiction, and was thus a pioneer of the subgenre of hard science fiction. His published works, both fiction and non-fiction, express admiration for competence and emphasize the value of critical thinking. His plots often posed provocative situations which challenged conventional social mores. His work continues to have an influence on the science-fiction genre, and on modern culture more generally.
Heinlein became one of the first American science-fiction writers to break into mainstream magazines such as The Saturday Evening Post in the late 1940s. He was one of the best-selling science-fiction novelists for many decades, and he, Isaac Asimov, and Arthur C. Clarke are often considered the "Big Three" of English-language science fiction authors. Notable Heinlein works include Stranger in a Strange Land, Starship Troopers (which helped mold the space marine and mecha archetypes) and The Moon Is a Harsh Mistress. His work sometimes had controversial aspects, such as plural marriage in The Moon Is a Harsh Mistress, militarism in Starship Troopers and technologically competent women characters who were formidable, yet often stereotypically feminine—such as Friday.
Heinlein used his science fiction as a way to explore provocative social and political ideas and to speculate how progress in science and engineering might shape the future of politics, race, religion, and sex. Within the framework of his science-fiction stories, Heinlein repeatedly addressed certain social themes: the importance of individual liberty and self-reliance, the nature of sexual relationships, the obligation individuals owe to their societies, the influence of organized religion on culture and government, and the tendency of society to repress nonconformist thought. He also speculated on the influence of space travel on human cultural practices.
Heinlein was named the first Science Fiction Writers Grand Master in 1974. Four of his novels won Hugo Awards. In addition, fifty years after publication, seven of his works were awarded "Retro Hugos"—awards given retrospectively for works that were published before the Hugo Awards came into existence. In his fiction, Heinlein coined terms that have become part of the English language, including grok, waldo and speculative fiction, as well as popularizing existing terms like "TANSTAAFL", "pay it forward", and "space marine". He also anticipated mechanical computer-aided design with "Drafting Dan" and described a modern version of a waterbed in his novel Beyond This Horizon.
Also wrote under Pen names: Anson McDonald, Lyle Monroe, Caleb Saunders, John Riverside and Simon York.

#23/Sentido común (1941)

Periodo en el que está basada:2560

En la continuación de ‘Universo’, nos encontramos, principalmente, con otro nudo y consecución (después del “del primer albor” de ciertos habitantes de la nave Vaguard al conocimiento de límite de ésta ,y todas las mentiras y desconocimiento vertido sobre anteriores y actuales generaciones de Terrícolas; con la posterior consecución del descubrimiento del verdadero Universo); el de los implicados: Hugh, Joe-Jim, Bobo y Alan, que tienen que lidiar con el bando enemigo de la nave (opuesto al despertar colectivo e incrédulo, supuestamente, -o más bien reticente- a que haya un universo verdadero y expandible, sin límites e intentar alcanzarlo, viajando hacía un astro y aterrizando en éste. ( y por lo tanto, libertad de obra, pensamiento y fronteras/metas). Así que, el jefe opositor: Bill Ertz es secuestrado y se le muestra el descubrimiento del universo real; siendo éste nombrado parte del grupo. Con esto, se pone en marcha la labor de traspasar las fronteras enemigas, para dar mensajes de paz temporal, reuniones, e intentar convencer al resto de los científicos del navío que ésta se desplaza y hay otros mundos fuera (como siempre, el pueblo queda fuera de ello). Realizando el anhelado viaje a Centauro que dictaminaba Jordan en sus escritos.

En ésta parte vemos al Heinlein más político- burocrático (y con suma acción en su último tramo), y siempre sumamente crítico, con la exposición de “todo el tinglado” que se lía siempre que hay que concretar un fin en común. Y es igual lo primitivos que sean los particulares (porqué recordemos que éstos, pese a su avance tecnológico en ciertas áreas, son primitivos en esencia; por desconocimiento jerárquico), pues siempre salen a relucir ( en acción y pensamiento) las suspicacias (ni los propios aliados se fían uno de los otros), los sectarismos (Joe-jim hace su propio bando de Mutantes, Los científicos el suyo, por ejemplo. Y pese a ser todos del mismo lado), el inevitable uso de la violencia (Motines contra el actual consejo de la nave y consecuente golpe de estado; en éste caso doble) y posterior guerra / traición por causa de la vuelta a la tiranía (utilizando el asesinato como política, entre otras perlas ilustrativas del ser) de uno de los supuestos ‘aliados’: el ayudante de Ertz, Phileas Narby, que consigue su objetivo, mediante el acople deliberado con Hugh, Joe-Jim, Ertz, Alan y Bobo, de erigirse el nuevo capitán de la nave. Todo va bien, hasta que un día Hugh le comunica que están en disposición de dar el “gran salto” y que se debe comunicar al resto de supervivientes de la nave. Aquí es cuando entra un nuevo pulso y batalla entre mismo bando (guerra civil en toda regla) a vida o muerte, ya que Narby desea imponer el orden, disciplina de antaño en la Vaguard, ocultando que la verdad sea de libre acceso a todos.

El título es muy significativo, pues aquí se establece como definición social mediante el punto de vista conservador y en teoría coherente del gran enemigo: Narby, que lo justifica como necesario atributo científico que debe otorgar la realidad y los hechos tangibles...pero ¿qué pasa con las maravillas inexplicables? ¿de dónde salió él y los suyos? ¿qué hay más allá?. No importa, siempre que se haga la suya y la mente enferma y estrecha vea como auténtica meta lograr ejercer el mando y mover los hilos de su reinado.

Un relato crítico, como expongo anteriormente, pero, además, significativamente oscuro y sórdido ( y ya no por la violencia que se haya en el desarrollo de toda la contienda bélico-política) sino por la tenebrosidad del alma humana y el hallazgo de el Apocalipsis sufrido (por causa político – social) por los primera generación idealista que embarcó en la Vaguard (mediante los diarios que encuentran en la nave auxiliar que datan de 2172, perfectamente conectado poco después de lo acontecido en ‘Los hijos de Metusalem’, en 2136), dando como resultado, deliberadamente, el rendimiento y la puesta en acción del desconocimiento y monotonía cómo política social de la nave en las futuras generaciones.
Evidentemente, Heinlein nos plantea que el hombre o ser no aprende, siempre empieza a girar la rueda del desarrollo para acabar en el mismo ostracismo, tiranía y pretensión de manipulación de la verdad y falta de libertad, con la inevitable guerra de por medio.

La consecución del objetivo de aterrizar por los pocos supervivientes de la Vaguard en un planeta, enlaza perfectamente con la generalidad piramidal-significativa de la obra maestra”Historias del futuro”, ya que mediante esto, podemos dilucidar una nueva era del ser humano y la vuelta a la población, mediante el posterior cruce de éstos con los otros supervivientes exiliados: Los Longevos de la gran familia Long (“Los hijos de Matusalem”). Es, pues, una segunda primavera de la especie humana y nuevo desarrollo de la cultura, sociedad y ciencia. Con la iniciación de la longevidad en la Tierra, al estar los detractores anteriores erradicados por causas de masificación natural, que conecta con así mismo con la epopeya “Tiempo para amar”, en la cual los escritos “bíblicos” son los de Long y sus vivencias (de primera mano, y ésta vez por un ser vivo, cómo referencia de estudio en las posteriores generaciones) y la alusión de Secundus cómo el segundo gran astro Terrestre.

Así pues, el perfecto cierre de “Historias del futuro” nos da cómo marco el nuevo comienzo, establecimiento y florecimiento del ser humano. ¿ésta vez tendrá una consecución más benévola y menos enfermiza para la sociedad finalmente?. Juzguen ustedes mismo. El maestro lo tenías muy claro.

Avances y/ o predicciones Tecnológicas:
-Nave auxiliar de aterrizaje dentro de una nave madre
-Alimentador de combustible mediante materia convertida en energía

Avances y / o predicciones sociales:
-Pérdida de la medida temporal y su tratamiento por aislamiento
-Alteración de la cultura Técnica ( por desconocimiento y pérdida de sus orígenes)
-Nueva migración Inter planetaria y alcance de astro (Segundos tras los longevos en la gran “Diaspora” en alcanzar y poblar otro planeta)
-Segunda primavera de la especie humana y nuevo desarrollo de la cultura, sociedad y ciencia.

Before the US entered World War II, Heinlein predicts an atomic doomsday weapon, envisions a cold war full of stress following WWII, with both sides having massively destructive weapons and increasingly itchy trigger fingers. He speculates a future in which the United States gets there first, as it actually did, and suggests a solution, a Solution Unsatisfactory, of the situation.

Though he got the particulars of what the first atomic weapon would look like a bit wrong, he's close enough in his particulars to resonate with actual historical problems. (As an aside, he's closer to a modern fear of dirty bombs used for terror.) What strikes me is that his solution, though terrible in many particulars, would seem an awful lot better at the time than what was actually done. If you could see in advance what was rotten about the Soviets, and he certainly could, and anticipate that they (and everyone else) would have similar nuclear power shortly after the end of the war, how can your plan be to allow the bloodiest dictatorship in history to become a nuclear power? The outcome we actually experienced -- four decades of growth and menace followed by a withering away, is almost certainly the best that could be imagined in the rear-view mirror. The thing is that this outcome was basically unimaginable before it happened. The menace was utterly predictable. How did we let that good outcome occur?

Heinlein has his characters take a route that I have to think would have seemed infinitely better at the time, but almost certainly would have worked out less well. In addition to being a fun and interesting story, it gives a lot to think about.

2015: I had to listen to this one again soon because I wanted to hear the new version in audio that came with Expanded Universe. I like this newer version better, but will hang on to the dramatized version as it has its own flavor.

Book #24 out of #21 for Heinlein's Future Perfect series (yes, I know that looks wrong, but that the official way to write it.)

"Common Sense" was written and released in 1941. This is the sequel to "Universe", and has a much more darker-tone than "Universe". These two stories are an absolute adventure, as I read all 128 pages (the complete "Orphans of the Sky") in one sitting.

Merged review:

The cutoff-date for me naturally enjoying something is about 1950. Anything before that, and either the pacing or style throws me off. This is an incredible story by Heinlein, but being written in 1941, it just felt hard for me to get into.

Clever use of Fiorello La GuardiaLa as the President!

This is an interesting take by Heinlein on the atomic weapons which filled science fiction stories of the '30s and '40s. Instead of the protagonists developing an atomic bomb, Heinlein has them developing a dirty bomb - a conventional bomb packed with radioactives. Heinlein proposes a solution to this problem (any "pip-squeak" country can construct one, conjuring up the picture of an international future analogous to a room filled with people each holding a loaded gun) : banning all aircraft and setting up an independent international Police Corps to enforce it. But it is an unsatisfactory solution... As well thought out as many of Heinlein's ideas were, he missed a trick with this one: he forgot about the possibility of a guy with a suitcase...

Before Pearl Harbor, before the war in Europe became a World War, Robert A. Heinlein considered the consequences of an unrestricted arms race. He foresaw the possibility of a "cold war", a time of tensions and uncertainty with both major powers possessing doomsday weapons - and increasingly itchy trigger fingers.

We approached the brink of nuclear war in 1962 - and stepped back. Witness now the prescience of the Dean of Science Fiction, who saw it coming in 1941. Follow an extraordinary chain of events extraordinary, leading to a problem unprecedented - and a "Solution Unsatisfactory".

Heinlein's prediction of the creation of doomsday weapons (weaponry capable of wiping out the human race) back in 1941 is so close to historical facts since that you can't help but shiver. His grapple with an eventual 'solution unsatisfactory' seems to cover most obvious possibilities. However, his writing here is more than dry and the way he plays out this story is from the perspective of someone not wholly military but a lifetime away from a civilian - it's a soggy middle if you ask me.

The repercussions of what began in the novella Orphans of the Sky, and the story behind one of the throwaway details from Time Enough for Love.

An interesting view on what can happen in multigenerational ships after things have gone wrong.

A few from a lost generation find a way off of the ship and by some miracle land on an inhabited planet. Fun short syfy tale.
