Fang Yun first briefly explained what dialectics is.

In fact, this is a widely existing way of thinking in the Tima civilization system, and it is also a way for the Tima civilization to perceive the world, and many Blue Star monks have come into contact with it.

To put it simply, dialectics is a philosophical doctrine about the unity of opposites, struggle and movement, universal connection and change and development.

The essence of dialectics is a method of seeking knowledge through criticism.

In the history of earth civilization, the earliest dialectic comes from the Chinese sacred book "Zhou Yi", which records the earliest written record of symmetrical dialectics of human beings on the earth.

The theory of yin and yang in Chinese civilization uses the interaction of yin and yang qi that oppose each other to talk about the generation and change of all things in heaven and earth.

Astronomical meteorology and seasonal changes are caused by the sympathy of yin and yang, and the world is composed of yin and yang, and all changes in the world are inseparable from the interaction between the two opposites of yin and yang.

"The Ancestor of All Classics": The "Eight Trigrams" mentioned in the Book of Changes and the doctrine of overlapping two hexagrams into sixty-four hexagrams are to explain the change and development of things from the contradiction between the positive and negative sides.

These are the origins of dialectics.

Of course, after teaching at Blue Star, Fang Yun could not and would not bring out the history of China to talk about things, and after Fang Yun introduced the way of thinking of dialectics, he began to give a real lecture.

The dialectical view of biology, or Fang Yun's view, is that all things in the void are mutually reinforcing, and there is no strongest, powerful creature, nor is it the strongest creature.

For example, the Void Silver Dragon, this kind of creature is extremely powerful, but what ended the Void Silver Dragon was some inconspicuous, almost worthless compared to the Void Silver Dragon. ”

Fang Yun pointed out that the root cause of the various diseases of the Void Silver Dragon was formed by various microorganisms that were difficult to see with the naked eye.

Although the Void Silver Dragon is extremely strong and powerful, and can devour the starry sky, they can't kill invisible microorganisms, so the Void Silver Dragon standing at the top of the food chain is actually not the strongest.

But at the same time, Fang Yun also proposed that the largest individual is still about equal to the strongest individual, because, purely in terms of individuals, a microorganism is far from being the opponent of the Void Silver Dragon.

But if you look at it dialectically, the strongest individual is not invincible, and will still be subject to all kinds of creatures.

This is the dialectical view of biology.

Fang Yun's point of view makes many people seem to understand it.

But at the same time, Fang Yun's point of view made those who were not biology students seem to understand it.

In other words, whether it was biology or not, in fact, when I heard Fang Yun's class, I had some special feelings.

It doesn't matter if you don't understand, Fang Yun has just started to talk about it.

It can be said that the 300,000 students on the scene have been attracted by Fang Yun's theory at this time, and have unconsciously integrated into the learning atmosphere.

Fang Yun continued: "Let's look at the second question, the most evolved race is about the strongest race, on this issue, here, I will first explain the orthodox biological level of Timar......"

In the Timar civilization system, there is a detailed division of biological levels.

After Fang Yun summarized it, he divided it into several categories, each of which included intelligent beings.

Fang Yun said eloquently: "From the perspective of bioenergy, organisms can be divided into two categories: feeding and energy uptake......

Feeding is the ingestion of food, which is then converted into its own energy through a special system.

Among the Timar civilization, this type of creature is the most numerous, and Blue Star is the battle star, but most of the native creatures of Blue Star are feeding creatures.

Feeder organisms are further divided into several categories, among which there are herbivorous, carnivorous, omnivorous, and intelligent organisms.

But either one, they all have a common characteristic, which requires the conversion of food into bioenergy.

Energy intake is a creature that draws energy directly from the universe.

Energy-absorbing organisms are also divided into many categories, and their characteristic is that they can directly ingest energy for their own use, without the need for energy conversion.

Fang Yun classified all kinds of elemental spirits, such as fire elemental spirits, wind elemental spirits, nature spirits, and so on, into this category, and Fang Yun also classified artificial intelligence, cultivation to a high level or above, and monks who had achieved a life leap as energy-regenerating creatures.

Of course, in addition to that, as the student just said, many of those powerful immortals are energy-regent creatures.

Energy intake is an important basis for measuring the degree of biological evolution.

The general belief in the Timar civilization is that the receptive organisms are of a higher grade than the predatory organisms.

Feeding and ingestion are easy to understand.

Fang Yun explained a little, and the students on the scene, even those who didn't understand biology, also understood seven, seven, eight, eight.

In addition to the way energy is consumed, the Timar civilization has several important criteria for judging the level of living things.

Fang Yun was not in a hurry, and explained at the beginning: "The second criterion is the way of reproduction, the biggest reason why artificial intelligence is difficult to be included in the category of biology is because they have no reproductive ability, which is an important sign of biology, so what are the common types of biological reproduction?"

The universe is vast and mysterious, and in order to continue, biological races have also given birth to a variety of reproductive methods.

However, as the saying goes, there are two main types of biological reproduction, individual reproduction and allogeneic reproduction.

Of course, in the eyes of a high-level biologist like Didihanka, the types of biological reproduction have become more complex, and Didihanka has a special point of view, biological reproduction is mainly "gene reproduction" and "source code reproduction." ”

If Didihanka's biological view is universally accepted, then artificial intelligence can also be regarded as an intelligent life, because artificial intelligence is a kind of source code reproduction.

In this kind of open class, Fang Yun couldn't talk about such esoteric theories, so he chose individual and allogeneic reproduction, which were more acceptable to everyone.

Individual reproduction is self-division, without male and female, self-division, reproduction of offspring, allogeneic reproduction is hereditary offspring.

This theory is also very easy to understand, above the blue star, there are hundreds of ethnic groups, but there are these two breeding methods, Fang Yun said a little, everyone has already taken a seat.

The third criterion for determining the level of a creature is dimension.

1D, 2D, 3D, 4D...... The ability to move in different dimensions is also an important criterion for judging the level of creatures in the Tima civilization.

The Timar civilization system believes that in order for everything in the universe to become a real creature and form a race, then, at least, this creature must also be quasi-three-dimensional.

In other words, at least a creature that can perceive the three dimensions of length, width and height has the ability to survive in the universe.

Fang Yun said: "For example, ants, this kind of creature is very low-level, but it is at least quasi-three-dimensional, it has no special concept of height, but it has a certain ability to climb high......

Fang Yun believed that there were more races in the Blue Star War Clan, all of which were considered normal three-dimensional creatures.

Of course, according to the different organisms, among the three dimensions, there are quasi-three-dimensional, weak-three-dimensional, three-dimensional, and strong three-dimensional.

Quasi-three-dimensional is a creature like an ant.

Weak three-dimensional organisms are organisms that can only swim, or can only live on land, or can only survive in the atmosphere.

Serious three-dimensional creatures are creatures with amphibious capabilities, and strong three-dimensional creatures are creatures that can fly.

When Fang Yun talked about three-dimensional classification, many students on the scene began to think about what kind of dimensional creatures they were comparing themselves to. As if he understood the student's thoughts, Fang Yun said with a smile on it: "Are you all curious about which dimensional creature you are?" Then let me tell you now, as intelligent creatures, we have already learned how to make tools, we have achieved flight, and some have even cultivated the ability to fly in the air, so in terms of biological level, we are at least strong three-dimensional ......."

Is it strong three-dimensional?

It seems that this is really the case.

A student asked loudly below, "So, may I ask, are those immortal beings who have evolved extremely well are four-dimensional creatures?"

Fang Yun shook his head and said with a chuckle: "Strictly speaking, whether we admit it or not, there are no four-dimensional creatures in the sixth-level Timar civilization, the immortal clan is very strong, it has surpassed the ordinary strong three-dimensional, their dimension, to be precise, should be quasi-four-dimensional ......"

Quasi-four-dimensional, that is, one has a certain perception of the four-dimensional, and even has a certain ability to dominate, but has not really entered the four-dimensional space.

Just like ants in the real world, they have a certain degree of perception and dominance, but their ability to perceive height is quite limited.
