(I aspired to write a sci-fi world as close to reality as possible, and I added my own ideas to it, but some of it didn't fit the mainstream contemporary view, and no matter how weird the content was, I imagined it with a serious and rigorous attitude.) ）

"On the Combined Effects of the Weakening of Blood Kinship", written 1.3 million years ago, the author of the article is unknown, according to relevant records, the author of the article was not known due to political persecution, and disappeared after the publication of this article. This article has been continuously exposed or hidden for more than a million years due to the progress or development of the entire civilization, but it has not been destroyed. I stepped through the door, took a cursory glance at the room that wasn't too complicated to decorate, found a device that looked more like a bed, and lay down sloppily, feeling the irritation on my skin as I sank in, and I continued to look at the messages.

"It has triggered our thinking and debate about the meaning of life again and again, and its impact on the 'past' can be regarded as deviant, but no matter how emotionally we do not believe it, as long as there is a little rational understanding of the current situation, it cannot be refuted. It can be said that it crushes one of life's proud features in an overwhelming manner and opens the way for future generations to continue their attempts. This is a complicated comment, one that a famous scholar was forced to publish half a million years ago, and yet no one forced him.

Not only the article "On the Comprehensive Effect of the Weakening of Blood Kinship", but a series of scholars who later published related articles formed a school of thought, advocating a major change in human social relations; At the same time, there is a school of thought that strongly opposes the abandonment of these once widely praised and relied on existences, among which blood relatives are the main representatives. But with the development of the times, blood relatives have inevitably embarked on the road of disappearance.

"First of all, you have to be clear about the concept," Gust began, "that human beings are not a race, and that the scope of human beings has been expanded, both in our civilization and in this one, and the standard interpretation is that individuals who have reached the level of intelligence and belong to a well-established and sustainable social system. This means that regardless of appearance, regardless of basic composition, as long as it exhibits such properties, it can be considered human, enjoy the same treatment as humans, and have the same communication as humans. Do you know what that means? ”

I was stunned, and opened the knowledge link that Dawson gave me, and then I found out that in fact, this East civilization is not only a human being who looks similar to the earthlings, but at present, there are more than one hundred and twenty species that are eligible to be registered as citizens, of which there are basically four categories, in addition to carbon-based and silicon-based, there are two that I have never heard of at all, but the government has not prevented the union between various races, and even encourages this kind of interracial love in some places, including childbearing, But my first reaction was that it was impossible to have children.

In fact, it is indeed impossible to do this through the normal way, although all races belong to heterosexual reproduction, but there are differences in details. However, the perfection of artificial reproductive technology has opened up the possibility: both parents provide their own cells, the relevant authorities copy the structure, and then both parties jointly decide whether the race of life is with the father or the mother, and the government also allows the parents to choose the characteristics they like in some aspects.

This technology has become so deeply embedded in society that almost all new generations, regardless of whether they are interracial or not, have chosen this method of reproduction. Because of the development of medical technology, people's diseases (excluding viruses) and defects have become a thing of the past, but it is better to plan for them from the beginning than to correct and modify them after the fetus is formed, and it is this idea that drives artificial reproductive technology to become a part of civilization.

After that, let's recall the objective reasons for prohibiting close relatives: to prevent the health abnormalities of the next generation and ethical confusion, but the existence of artificial reproductive technology makes the physiological conditions no longer a restriction, and at the same time, because of the continuous expansion of the territory, people are faced with more and more complex things, and everyone's relationship has also changed, and family relations have begun to mix with other elements: friendship, teacher-student relationship and even - love. The concept of blood is diluted in people's hearts because of artificial reproduction, and family affection naturally begins to fade, but this does not mean that there will be fewer people who are close to each other, and it should be father and son but they are called brothers, or teachers and students, and those who are originally brothers and sisters are called brothers, confidants or ...... Mate. That's right, since there are no restrictions on interracial love, there is no reason for same-sex love to be opposed.

All of this makes this absurd conclusion come true, the traditional ethics of the Easth civilization are simply unthinkable to Earth, but it cannot be called "incest", because in reality it is not chaotic at all.

First of all, let's understand the opposite sex, male and female, in our primitive period because of the need for the female uterus as a reproductive tool to maintain the number of races, so the status of women was high; In ancient times, such a phenomenon as racial destruction was no longer possible, and all forces needed to develop and compete for hegemony by force, so the status of men was raised; Today's earth tells us that the gap between the status of men and women has become smaller and smaller, and the needs of the times determine the status of men and women.

In the Easter civilization, men and women are almost literally different, even in terms of body contours, and because of the excessive pleasure of sex and behavior, the government has long been working to reduce the level of happiness in artificial reproduction, and this project has been unanimously agreed by almost all citizens, because everyone thinks that our attention cannot be wasted too much in this area, and there are many ways to achieve happiness. As a result of this change, there is no disparity between the status of men and women, as there is almost no difference.

Moreover, because "sex" has been sanctioned, the concept of love has also undergone major changes, and love has become a run-in between two people who are purely lonely and attracted to each other, and the formation of a family means that both parties recognize and trust each other, and the inheritance of the next generation becomes irrelevant. Because with the development of technology, the lifespan of human beings has generally reached between 500 and 1,000 years. It is for this reason that the relationship between people can only be one-to-one, and one-to-many will only arouse pity or discrimination from others.

So the emotional aspect of almost all citizens is cautious and single-minded, and also pure. In contrast, the emotions of the earth are inferior. In addition, because of the variety and variability of appearances, people do not pay attention to these unimportant things, but pay attention to those unchanging, which belong to internal factors such as thoughts and spirits.

――

At this point, I exhaled, I have a vague idea of the current culture of civilization, although it is different, but because the influence of the earth factor in my heart is not too deep, but more identifiable.

Kinship dilution ...... In fact, there are a lot of involved, I looked at dozens of links that were not clicked on the side, and I couldn't help but sigh that no civilization is simple.
