In essence, this story is about how a certain person was searching his bookshelf for something to read and in the end found a book, which turned out to be the source, from which it is possible to obtain absolutely any kind of information about absolutely any person. Meaning, information to the smallest particulars and details about what his or her qualities of personality are, how he or she lives, what he or she really wants to achieve, what he or she hides, and much more. And, it does not matter, if the subject is some person, who lived in the distant past or lives in the present or someone, who will live in the future. Since, as it turned out later on, this literary monument is nothing other than the Catalog of human population. In other words, the encyclopedia of Homo sapiens; in essence, the same as encyclopedias, reference books for specialists, which contain complete information about representatives of a particular subspecies of animals, plants, etc.Although at some point, the course of this story turned banal: "bad guys" from security services, intelligence services, politics decided to not only use this source of knowledge for their dirty deeds, but also to appropriate it solely for their personal use. And, the way they tried to do this is also banal: by physically destroying the author of discovery of the Catalog of human population and all of his colleagues. However, the ending of this story makes it stand out from the category of ordinary spy stories. At least because the main characters of this story managed to survive not due to favorable concatenation of circumstances or someone's help, but thanks to that knowledge, which they discovered in the ancient text, which turned out to be the Catalog of human population.Of course, such an outcome upset and continues to upset not only the Russian special services, but also all those people in whose way developers of the Catalog of human population got. And, in this civilization, there are countless numbers of such people: from psychologists (who become no longer needed by anyone) to organizers of this civilization themselves. Since from the standpoint of the Catalog of human population-technogenic civilization without a human, which they lovingly built for many centuries, is simply trash, to put it mildly, and beneath all criticism. And, they themselves are also trash.However, regular people, who (thanks to the scientific discovery made by Andrey Davydov) got the source with answers to all of their questions and individual recipes, now no longer need to pay "experts on the human soul" for being shamelessly fooled. Therefore, whoever tries to kill developers of the Catalog of human population in the future must know that it is no longer possible, as they already became part of history of humanity. After all, at the current stage of development, a Homo sapiens has only one possibility to continue to live after death, to live through the ages: in the product that he/she created. And, those, who tried and continue to try to kill them, were nobodies and will remain nobodies, who one day will cease to exist without leaving a trace.As for organizers of this "civilization"-maybe instead of trying to find new recipes to destroy "excess billions" and trying to examine human potential using Neanderthal methods, it would be more reasonable not only to find out the recipe of how to make Homo sapiens a 100% controllable producer and consumer from the source (which, by the way, seems to have been left to humanity by creators of nature and a human on this planet), but also how to build a civilization without quotes? After all, it only seems to them that they are the main deceivers, while in reality they were fooled, and fooled majorly.
