I’ve been covering Asimov’s early works in groups of eight or nine stories (including a novel length work in the last batch) but the last nine stories Asimov wrote in the 1940s  include two novel-length works, one of which has two significantly different versions, so I’m only covering the six shorter works in this post and will handle the other stories as normal book reviews. In fact, except for finishing up the first volume of Asimov’s autobiography and a last special post related to this era, I plan to review the remainder of Asimov’s works in normal individual book reviews.
The first two stories in this period of the late 1940s following “The Mule” were both Robot stories.
In “Evidence,” Stephen Byerly is a lawyer running for mayor as a reformer while Francis Quinn is his unprincipled opponent out to smear him with the charge of being, basically, a robot brain in a human-like body (which is a damning accusation in a society which despises robots and doesn’t allow them in the general population). But it’s difficult to to prove someone is a robot when they’re implicitly recognized as human under the law, with full rights including the right to privacy. Conversely, trying to preserve those rights while proving you are in fact not a robot isn’t much easier. Still, a way is found for the proof for or against at the climax, but it is the denouement with Susan Calvin at the end which packs more punch.
My one problem is that, despite what the story says, it seems to me that the proof that someone is not a robot is easy and, though proving that someone is would be hard, convincing people of it wouldn’t be. Simply order the being to do something no sane and self-respecting human would do. If the person disobeys, they’re not a robot (Second Law) and, if they do it, they are either a robot or at least not a sane and self-respecting person most people would want for mayor. But if I’m wrong there or if you overlook that problem, this is an otherwise effectively written story which carries some emotional weight and is very good.
Despite the conflict, “Evidence” is basically an upbeat story of sorts. “Little Lost Robot” is much darker. While working on experimental hyperdrive starships, which is dangerous, robot labor is useful but robots interfering with the work to “save” humans from danger is not, so special robots are secretly built with a modified first law (and less stable minds). When a human tells an intrusive special robot to get lost, the robot mixes in with sixty-two other robots with normal First Law programming, but who are otherwise identical. If people find out that the unstable robot exists, it could be very bad for the government and for U. S. Robots & Mechanical Men, so Susan Calvin and Peter Bogert are sent out to try to identify the robot. Because the robot is unstable and has developed a superiority complex, it becomes a battle of wits with a robot whose First Law prohibition against harming humans was intentionally weakened and is now almost non-existent.
Like “Evidence” and others, a solution to the problem is fairly obvious but Calvin and the rest do not see it until they do something very similar near the end (which is itself a problem as more than one Robot story involves repeated attempts at solving the problem before a final success which hinges on something which should have been determined when initially establishing the domain of the problem). Asimov goes to great lengths to explain all the dynamics with the strange robot and perhaps succeeds but I wasn’t entirely convinced this time. The effort at writing an almost pre-Asimovian “robot menace” story provides much excitement but at the cost of seeming contrary to most robot principles in the series. But, once again, if you accept the premise of this particular tale, it works well.
After writing the story which made up the first third of Second Foundation, Asimov turns to a story that isn’t connected to those series and is coincidentally named “No Connection.” It is connected thematically to other stories, though, being somewhat like “Homo Sol” and others in portraying humans (or the like) as weird beings who are inexplicably violent and, more than that, are beings who have a sort of vice in peace which inverts so that they have a sort of virtue in war. It’s also akin to “The Weapon” in the sense of having wise old “aliens” or “The Weapon Too Dreadful to Use” in that and in having, well, weapons too dreadful to use. It is unusual in being on an Earth so far removed from ours as to feel like an alternate world in that the “Americans” the story opens with turn out to be Gurrows, or civilized bears whose society is extremely egalitarian and “”social without being gregarious,” while beings evolved from chimpanzees and called Eekahs inhabit the other continent. The particular Eekahs who make contact with the Gurrows are fleeing political persecution (which the Gurrows can barely comprehend) from their society which is “gregarious without being social.” The protagonist, an archaeologist interested in the concept of a “Primeval Primate,” can’t see the connection between several things, including the Eekahs, the Gurrows, the odd results from using the Eekah knowledge of radiation to date things and more, but the reader comes to see, sooner or later, that it’s all connected after all. (Actually, in this, it’s also like “Not Final!”) It’s a very interesting depiction of an alternate sentience and society though the story, by its very nature of providing the reader but not the characters with a “conceptual breakthrough,” isn’t fully engaging.
For something very different, “The Endochronic Properties of Resublimated Thiotimoline” is a fake science article, so doesn’t really have any people, places, things, or plots except the thing of thiotimoline, itself, which is a substance which dissolves prior to hitting the water. But it’s a very thoroughly and cleverly done spoof which actually may have counted in Asimov’s favor with his Ph.D. examiners because he obviously had to know what he was talking about to fake it that well. Despite the time travel bit, some readers somehow even thought it was a real science article. I’m not sure if this was historically first, but it’s the earliest example I know of what has become a microgenre of its own. (“Meihem in ce Klasrum” predates this by about a year and a half, but is more a fictional essay on spelling than a fictional scientific paper.) If you’re susceptible to the notion, this is a very funny lampoon of academic papers and has a very entertaining idea as well.
Asimov next became embroiled in the difficulties with “Grow Old with Me,” which finally resolved happily after quite some time. Meanwhile, he wrote more stories, including “The Red Queen’s Race.” This is a time travel story and is one of the minority which appeals to me because it avoids logical inconsistency. Even aside from that, it’s also very good. A “flatfoot” playing a dumb cop (when he’s definitely not dumb and not any ordinary cop, either) investigates the mysterious death of a physicist whose last act was to somehow drain an entire atomic power plant. The only real clue is a chemistry book he was having translated into Greek. The cop interviews several people but the most interesting comes at the end when a philosopher does a remarkable point/counterpoint presentation of views of ancient history. This story has references to the then-undetected neutrino, to what would become chaos theory and how remedying the lack of a “mathematic psychohistory” would be helpful. It also has some interesting details in its time travel mechanics. It isn’t a real action-packed tale and the philosopher appears too conveniently, so it might not be an epochal classic or anything, but it’s a very good, idea-packed story with a good narrative voice.
Asimov quickly followed that up with a second superb story, “Mother Earth,” which, like “Blind Alley,” is related to the Robots/Empire/Foundation universe without generally being included with those main stories. In this, several scenes of conversations between major and minor exemplars paint a picture of a “Terrestrian” society of billions packed into a single planet where the soft sciences are strong and robots are despised and an “Outer Worlds” society of fifty loosely united worlds out in space made from human colonists who have developed eugenically-controlled racist low-population societies built on robots and the hard sciences and who despise the people of Earth. For decades, tensions have been building and the Ambassador to Aurora, Luiz Moreno of Earth, turns out to be a proto-Seldon character who is leading a three-pronged “Pacific Project” which everyone believes is either misdirection or some vast secret when only a third of it is truly hidden and the other two-thirds are hiding in plain sight. This is short on physical action (despite an off-screen Three Weeks’ War) and long on concepts which build an astonishing amount of tension in the best Robot/Foundation tradition. The reader can fruitfully argue with some of the premises and dynamics and may approve of some ends but not means (or vice versa) but, however the reader approaches it, there is much to engage with, from ideas on psychology and history (and even psychohistory), overpopulation, eugenics, racism  , the surprising difficulty of deciding who the actual winners and losers of wars are (an issue I’ve noticed myself from Alexander’s conquests to WWII and beyond), and strange premonitions in this 1948 story of things that would soon occur (as well as something which soon proved to be backwards). While much of this story is covered in earlier Robot and Foundation stories (and some others) and would be covered again in later ones in different ways, this a fascinating and key story for most readers, I’d think, and certainly for Asimov fans.
