Introduction
The scientific definition of consciousness is an interdisciplinary problem of modern science. Philosophy, psychology, biology, and cognitive science provide divergent answers to the questions: "What is consciousness?", "How did it develop and develop?", "How does it interact with the material world?", "What is the purpose of consciousness?"
There is also an acute problem of mutual understanding of terms by representatives of different disciplines, as well as between them and ordinary people. This problem reinforces the development of anti-scientific theories about consciousness. In turn, within the scientific community, the understanding of consciousness continues to dominate exclusively as an inherent feature of the human individual. This simplification does not develop a systematic understanding of the development of consciousness and matter in general.
In the current decade of Artificial Intelligence (hereinafter AI), the problems listed above create a large number of difficulties in studying this topic. So, many established scientists find it difficult to answer the question "What is consciousness?", not to mention non-specialists.
At the same time, the answer to this question is capable of answering the main question of all mankind: "what is the purpose, result, and true meaning of human (subject) existence?"    
The purpose of this article is to put forward a theory that will not contradict the basic provisions of advanced science, but at the same time will allow us to coordinate the stages of consciousness development, to give a complete terminology on this topic, using knowledge of philosophy and natural sciences.
Based on the assessment of the history of the development of consciousness and matter, it is proposed to put forward an answer to the question: "What is the purpose of the development of the subject and how do we achieve it?"
In this regard, the author offers his vision of the further development of mankind.
The theme of the competition is INTELLIGENCE AND THINKING.

General terminology
Matter is everything that exists outside of consciousness and desire, having a set of qualities and characteristics that are possible for perception. In other words, the material is everything that exists without the need for perception and processing by the subject (processing means the process of receiving irritation and transmitting information about this irritation).
Information is an external stimulus already processed by the subject (i.e., it is possible for consciousness to use), which has a content in the form of a set of characteristics obtained during the reflection of matter by the organs of perception. And it doesn't matter what this external irritation will be: an electric current, a shot from a cannon, thunder in the distance, tactile sensations. It does not matter how it will be transmitted in the process of processing information: by electrical impulses, hormones or ions of matter. Thus, information is a representation of some kind of influence.
Matter, like everything in nature, exists according to patterns:
1) It is eternal in time and infinite in space,
2) Any phenomenon of matter is always deterministic,
3) Matter cannot be completely destroyed and created out of nothing,
4) Matter cannot be static,
5) Matter cannot be defined as a constant by naming its qualitative properties. Its properties are inexhaustible.
The subject is a highly organized system of matter that learns the laws of the objective world and transforms it on this basis.
Being is a collection of matter that directly irritates the subject during the existence of the subject's consciousness. Being is everything that surrounds and affects the entire system of the subject in a particular place and time, for example, people's words, the weather outside, tea, Boris the cat, etc. 
Being, as a separate part of the material world, also has patterns of its existence within the relationship of consciousness and matter:
1) There is no being without a subject, and a subject without being,
2) Being obeys the laws of matter,
3) The subject's understanding of being depends on the subject himself,
4) The same matter, which is the being of the subjects, has a different effect on them with a difference in their abilities to perceive being,
5) Being in itself is essential = matter.
Consciousness is a part of the subject capable of perceiving the material, converting irritation from the material into information, analyzing information about the material based on existing algorithms, as well as creating new algorithms to meet their needs and goals.
Consciousness is precisely a cumulative ability, but not a specific organ or apparatus. Consciousness cannot exist without the perception of the material world, the transformation of matter into information and the analysis of information.
The mind is the main part of consciousness that analyzes and systematizes information, creating on its basis a conclusion in the form of an algorithm of behavior for the entire system of the subject.
The mind is a separate part of the mind responsible for satisfying the needs of consciousness. Example: meeting the need for an effective analyzing process, meeting the needs of communication, the need for the security of the entire subject, etc.
The mind is a separate part of the mind responsible for satisfying the needs of the material part of the subject (i.e., the rest of the subject's system).
Need is the knowledge of a certain need to maintain the possibility of the subject's existence, which arises after understanding the variability of the subject's being and system.
An idea is everything that exists only in the mind of the subject and has no direct influence (influence by the usual fact of existence) on the material world, but at the same time it can arise only from information obtained during the perception of the external world.
The idea, as a product of the development of matter, exists according to the following patterns:
1) Exists only in the presence of the subject and only in the consciousness of the subject,
2) It is always based on the perception of matter,
3) It can be created from another idea only if this idea has the perception of matter under it,
4) The idea obeys matter and is dependent on the laws of matter,
5) Information becomes an idea as soon as consciousness transforms information into knowledge (information that the mind has analyzed),
6) One or another idea will be objective to one degree or another, since it is based on the perception of the influence of one matter (external) on the system of matter of its subject.
Knowledge is information that the mind has analyzed for further ideal action with it.
Primary information is initial information that implies only the fact of the presence of an object or subject, without information about any other characteristic. The subject is only able to isolate the primary part of understanding himself, i.e., only the fact of his own existence.
Example: "I think, therefore I am," Rene Descartes.
The degree of self–awareness is an indicator of the development of the entire system of consciousness, an indicator of the ability of consciousness to perceive and analyze information.
But self-awareness cannot manifest itself in every phenomenon and be an integral part of any action of the whole system of the subject.
Self–awareness is a characteristic of consciousness that reflects the level of interaction of constructs of the entire system of the subject.
The actions of the subject, his responses and the processes taking place inside him can be: conscious, unconscious, conscious and unconscious.
Conscious action is an action that proceeds according to an algorithm created by consciousness, i.e. the response of the entire system of consciousness. An unconscious action is an action that proceeds according to the objective laws of matter with the subject's system itself, i.e., what matter itself produces in relation to external stimulation. For example: the skin is destroyed by chemical burns.
Conscious action is an action that takes place under the supervision of the entire consciousness (which is inherent in intellectual consciousness), in which the conscious will of the subject, which arose in the process of intellectual analysis, is expressed. For example: human thoughts, i.e. actions that are not subject to reflexes and instincts. An unconscious action is an action that proceeds according to algorithms created by consciousness, in which additional energy is not expended for conscious action. For example: reflexes and instincts.
Self-awareness of the subject
The process of forming consciousness as an integral construct with special abilities from the definition above ends with self-awareness, understanding of oneself. The moment of self-awareness indicates that the material part of the subject's system has the proper level of development to ensure the work of consciousness. 
Consciousness begins to perform its functions and gradually increase the survival abilities of the subject.
Question: When and how did consciousness appear?
 

Answer: The ability to perceive and transform (due to the difference in the characteristics of matter) the influence of different matter on other matter is the main property of all matter. Determinism (the constant interconnection and mutual influence of all matter) will exist only in a world where all matter can influence other matter. Since matter is not equal to a constant, it constantly changes and acquires different properties, therefore, it perceives different influences in different ways. Some compounds affect each other simply by changing substances, others enter into complex chemical reactions. But some substances combine faster, creating stronger chains. One of these substances is nucleic acid, which is capable of creating polymers. Due to the interaction with hydrogen, monomers created in connection with hydrogen constantly acquire new properties and structure (conformation). Further, the compounds were joined by increasingly inert chemical compounds. Only the most active substances remain, from which even more complicated substances appear, which, in order to successfully interact with other substances, constantly complicate and increase the number of processes within themselves. This whole process proceeds as a set of accidents repeated over billions of years. As a result, due to one accident, a substance appears in the composition of the monomer that can store information from external stimuli and analyze it. This substance is part of the same system with others. The rest of the molecule begins to obey the complete system, and so the first consciousness took place and with it the first subject.
Question: How did the subject become aware of himself?
Answer: The first thing that consciousness felt was the material part of the subject.
His compounds, molecules, how other compounds affect his new "body", how his molecules in response to irritation secrete various enzymes, which the DNA of our prokaryote analyzes. And it is worth saying that self-awareness is a separate quality in the development of consciousness. Different levels of understanding of oneself, one's actions, and needs are interrelated with the development of consciousness. The subject definitely receives the first self-awareness when his full-fledged system appears.
Question: Why is awareness the moment of acquiring the whole system of the subject?
Answer: Since without acquiring the entire given system, the further existence and development of the subject is impossible. He will have to either degrade or become a lower consciousness (realize himself as a system).
The first idea of such a consciousness will be knowledge. Since for the appearance of such a complex thought as an algorithm (instinct) or a set of algorithms (reflex), initial knowledge is necessary.
That is why consciousness first recognizes itself, the system gives information to consciousness, thereby transferring knowledge about the organs of perception and the environment.

As we could see on the third question, any system can develop along the line:
1) Creating a new system,
2) Bringing it to the maximum possible development,
3) Transition to a new qualitative level of the organization or death,
4) And so on up the spiral.
Based on the above pattern, we can conclude that there is a possibility of a qualitative division of consciousness according to the level of development of the organization of the system.
At the same time, we recall that any ideal is formed and transformed only under the onslaught of material necessity. Consciousness developed based on the needs of a highly organized system of matter – the subject.
The general mechanism of consciousness development, in our opinion, is as follows:
1) The first subject appears, his consciousness analyzes information from parts of his system and forms a need,
2) Consciousness remembers for a certain time (depending on the development of the organism) information from parts of the system and the irritation they receive,
3) Depending on the "power" of consciousness, the subject analyzes the information and systematizes it into patterns,
4) Depending on the influence on the entire system of the subject, consciousness develops a reaction to a certain irritation,
5) Depending on the success of this reaction and the frequency of its repetition, the first sequential algorithm is created (for example, instinct).
The body, in order to meet its needs, complicates the system and develops it further, developing new algorithms.
6) The body sooner or later reaches the maximum capabilities of its current system and begins a qualitative leap in the capabilities of consciousness and the system as a whole. This is how a reflex appears in more developed organisms, which are a set of patterns of instincts regarding material conditions.
A reflex is a pattern of instincts, because a reflex is always based on a pattern of external irritation and information about the success of a particular instinct. In other words, it is impossible to develop a reflex contrary to instinct. Every reflex will be built around instinct.
Example. The dog will resort to the feeder when called, because it knows about the possibility of satisfying the urges of instinct: "satisfy hunger." Instinct seems to be telling the dog: "If you eat, it will be good, food will lead to good things."
It is important to note that in this process of consciousness development, the main role is played by the variability of being of each subject: for example, some organisms can stop their active development at one stage, while others will develop constantly.
Stages of consciousness development
Further, based on the conclusions made in the previous part of the article, the author proposes a structure of stages of consciousness development according to the following criteria:
1. What characterizes this stage?
2. The working definition of the stage.
3. The degree of self-awareness.
Based on the analysis of the data of positive sciences and philosophy, the following stages can be distinguished: 
1) Proto-consciousness.
1.1) This stage is characterized by unsuccessful attempts by DNA and RNA to build a subject, because these are chemicals that have just begun to build into the future system. These molecules do not have consciousness, but have an initial ability to perceive and transform irritation (into information). Molecules learned to perceive irritation, create information from it and store it much earlier than the first subject appeared.
1.2) Proto–consciousness is a collection of molecules that are not subjects, but capable of perceiving and converting stimuli into information for parts of this set.
1.3) Degree of self-awareness: none.
2) Lower consciousness.
2.1) This stage is marked by the emergence of an integral subject who has not yet acquired either instincts or reflexes. This consciousness has only a biotic irritability on the part of its system and being, but does not have a pronounced, independent purpose. The lower consciousness has only the abilities received from the components of the system: to attach monomers and transmit information about their influence.
One can cite as an example of lower consciousness a language model such as ChatGPT, which has no expressed goals other than those set from the outside, but only information and the possibility of finding it. This consciousness does not yet have a need for anything, it does not analyze its state. The need arises immediately after analyzing the first information about the change of its subject.
2.2) The lower consciousness is the primary consciousness that arises when an integral system of the subject appears, possessing only primary information and the potential for its processing, existing without knowledge of the laws of being and any algorithms of behavior.
2.3) The degree of self-awareness: the subject can understand only the primary information about the presence of himself.
3) Instinctive consciousness.
3.1) At this stage, the subject is aware of his minimum needs and learns to satisfy them with the help of instincts. The need can only arise from the analysis of information about being. An instinct arises from the need to change being. For example, there is a lower consciousness, it has neither needs nor the ability to set a goal itself, there is only an understanding that it exists. But as soon as this structure, or its state, or the state of being changes (for example, time passes), it acquires a need. For example, a stream of monomers passed, took away a part of a certain system, and it had a need to recover; or a certain amount of chemical was needed for the system to work, and so the first need turned out. This need arose as a deficit for a certain system and was transmitted as information. As soon as consciousness perceives a change in being and its system, you acquire a need, since the influence of material objects on each other is expressed in a change in the properties of the matter involved in the reaction.
Instinct is the reaction (algorithm of behavior) of consciousness to a certain constant irritation (need), expressed instantly and without additional analysis, instinct is an already created algorithm based only on observation of patterns, providing the basis for the consumption of the body. It is thanks to instincts that consciousness can satisfy its needs and put them as the basis for the rest of the algorithm system. Instincts arise as a pattern in observing changes in the external environment in the action or inaction of the body (the body itself does not give commands to action or inaction based on the feeling of the external environment, they will not be directly related to a new stimulus, the body has not yet created the first complete algorithms of the subject's behavior). The unconditional reflex (BU) is an innate reaction of consciousness to a certain irritation, expressed instantly and without additional analysis, cannot be lost, since it is the main algorithm for providing instincts and relies strictly on constant irritations of a subject of a certain structure. BU is the same and is inherited for subjects of the same structure, because of their common existence and needs. There is a difference between instinct and BOO. Instinct arises as an understanding of one's needs and an understanding of the possibility of satisfying them. It contains the simplest patterns of response to any irritation. It does not contain specific isolated actions, it contains in its essence an understanding of what the body needs, and at the most minimal level it is able to produce behavior algorithms. For example: to consume what is necessary, to give away what is superfluous, to preserve oneself.
And unconditional reflexes are already separate algorithms for providing reflexes, which gradually become part of instincts. For example, you need to consume by swimming up here, highlighting one thing and digesting the other. Unconditional reflexes appear after instincts and serve as patterns of an already worked-out algorithm system (i.e., it was worked out before by its action or inaction before consolidation).
3.2) Instinctive consciousness is a consciousness that arises after the appearance and satisfaction of the instinct of the first need of the subject, which has information about the relationship of certain conditions with the satisfaction of its needs and changes in its structure and, based on this pattern, implements algorithms of behavior.
3.3) The degree of self-awareness: the subject can perceive the simplest characteristics of the objects surrounding him (good or bad for the body), and give the rest of the system various instructions according to the simplest perception.
4) Reflexive consciousness.
4.1) Such a stage is characterized by the presence of consciousness, which has instincts and the ability to memorize a significant amount of data about being, to carry out the relationship between the actions of the subject and the satisfaction of their needs based on stimuli in being. Such a consciousness is able to satisfy its needs faster and more efficiently. Reflex (conditioned reflex) is an acquired reaction (algorithm of behavior) to a stimulus created during the development of the organism, based on instincts and already conscious action or inaction of the organism, carried out before receiving a stimulus (understanding the correct algorithm to meet needs). Consciousness already draws a parallel between the stimulus and instincts (direct action of the whole system). Based on the result of a certain reaction, reflexive consciousness creates an algorithm of behavior that is not inherited, but is the same for each individual of the same species (because all individuals have approximately equal conditions and needs). Due to the similarity of living conditions and with the constant repetition of the reflex (conditional), the latter is fixed in the form of an unconditional reflex, which is transmitted through DNA.
4.2) Reflexive consciousness is a consciousness that arises after the creation of the first conditioned reflex, which has information about the relationship between the body's actions and satisfaction of needs through stimuli in the external environment, based on this connection forming behavior algorithms.
4.3) Degree of self-awareness: the subject can perceive complex characteristics, such as the special shape of the object, for example, roughness or smoothness, etc. There is an awareness of their abilities and actions.
5) Intellectual consciousness.
5.1) At this stage, a consciousness arises that has pronounced abilities to conceptualize and analyze information. This level of consciousness compares instincts, reflexes and extensive information about being relative to the stimulus. This level of consciousness is the most energy-consuming of all biological levels of consciousness. The actions of the intellect take much longer to produce than the actions of reflexes and instincts. The intellect is gradually released from the framework of the obligation to act according to instincts, thanks to the development of reason and the gradual suppression of the rule of reason. But instincts still strongly influence the constituent parts of the subject's complex system. By this time, the system of consciousness had learned to distribute and transfer its functions between the components of the system. It is important to note that the process of developing intelligence is gradual. So, the crow will have the beginnings of intellectual consciousness, expressed in the ability to find insight. Monkeys are capable of abstract thinking. And the advanced HOMO ERECTUS is already making full use of cognitive simulation. In this regard, it is necessary to give some terms. Intelligence is a conscious reaction to a stimulus created during the observation of several objects with a simultaneous analysis of several objects, based on reflexes and instincts, thanks to intelligence, consciousness builds a logical chain between objects of being, instincts and reflexes to "insight". Intelligence does not imply a specific single reaction or algorithm. It is the ability to create a conscious reaction. In other words, intelligence is a mechanism for creating a complex algorithm. Insight is an understanding of the essential relationships and structure of being, through which satisfaction of a need is achieved. Outsight is an erroneous understanding of essential relationships and the structure of being, through which satisfaction of a need cannot be achieved. A logical chain is a sequence of searching and analyzing interrelated knowledge (conclusions) about being, leading eventually to an insight or an outsider.
Abstraction is a conscious reaction to a stimulus created during the observation of several objects and the simultaneous analysis of several objects, in which the subject is aware of the general properties of these objects and uses them for conscious thinking by distracting from certain characteristics for selective analysis of the properties of the object or subject. Cognitive simulation is a conscious reaction to an irritant created with multilateral knowledge about the object that irritates the subject (including abstract knowledge), expressed in the simulation of the subject's being in consciousness and the fitting of actions of something in this being. Generalization is a conscious reaction to a stimulus created in the presence of an abstract connection between several objects, in which consciousness deduces a pattern from the general properties of objects, which consciousness will repeat with any coincidence of properties until it understands the impossibility of applying an abstract reaction (outsit). The difference between generalization and other reactions is that generalization is the relationship of specific properties of several objects that can be generalized and built into a system of knowledge. In abstraction, consciousness is aware of the commonalities between objects and studies the particular. And when generalizing, consciousness studies the general, omitting the particular.
5.2) Intellectual consciousness is a consciousness that arises after the formation of the first insight, possessing multifaceted information about being and a large set of reflexes, forming through logical chains and intellectual conscious reactions (cognitive simulation, abstract thinking, visualization, etc.), insight or outsight, which form complex algorithms of behavior.
5.3) Degree of self-awareness: the subject is able to perceive abstract characteristics, deduce new objects from others, adding up their characteristics. There is an awareness of oneself as an excellent individual in a pack, a developed society of animals.
6) Civilizational consciousness.
6.1) This stage distinguishes the existence of consciousness in an artificial (created by the subject himself) environment, in which social (social) relations arise between subjects. It is important to note that civilizational consciousness does not mean the complete artificiality of the subject's environment. Civilizational consciousness means the active role of the subject in changing the environment to meet their needs. The variety of influences on the environment and existence itself for each individual subject leads to differences between subjects, expressed in cultural, social, hierarchical and other discrepancies. With the advent of the first civilization (at the birth of productive labor), the mind gradually begins to fade into the background relative to the mind. This is due to the improvement of the subject's ability to fill the needs of the subject's material system, without spending a lot of time on these actions. Consciousness at this level uses the intellectual abilities of the mind and reproduces active communication in society.
This communication, according to Alexander Yakovlevich Kaplan, allows subjects to interact with each other at a high, model level, describing a particular phenomenon, accelerating the process of development of the entire set of subjects as a whole.
6.2) Civilizational consciousness is a consciousness that arises during the creation of a developed society of subjects of the same type capable of independent productive work, possessing a huge set of information, experience of behavior and abilities of the system itself, which allows subjects to actively transform existence themselves through a developed intellectual consciousness, which leads to the formation of civilizations of subjects.
6.3) Degree of self-awareness: the subject is fully aware of himself in various qualities, actively using intellectual techniques to ensure his consumption, uses generalization and abstraction to create active concepts about his society. In the system of the mind, reason gradually gives way to reason in the course of the development of the possibilities of civilization. The instincts of knowledge are reaching a new level due to the increasing need for the constant development of civilizations.
7) Cybernetic consciousness.
7.1) This stage may be the potential future of subjects capable of creating advanced information technologies that can accelerate the process of data analysis billions of times, including through biotechnological development (artificial transformation of the body into new qualities). This future will come after the emergence of a technological singularity. A technological singularity is a hypothetical technological development of a civilization that will become uncontrollable and irreversible, which will lead to serious changes in consciousness. The subject may eventually come to such a stage of development, because He began to actively transform matter to suit his needs, and not only where there are initial conditions for this transformation. Humanity is squeezing all the juices out of its old biocomputers to reach new heights of technology, putting on huge body suits to protect itself from super-hostile conditions.
Even the use of gadgets that use information transfer as the main technology leads us to cybernetics. If our set of subjects wants to develop further, it will need: a) a mind capable of reproducing billions of analysis processes simultaneously, b) a subject system that is ideal for any existing existence, c) a system of organization of society that will allow us to continue the steady march of progress towards perfection. The first two points are possible only when the abilities of a biological species and advanced technologies merge. This merger will lead to a point of technological singularity, when the development of our human species will grow exponentially.
7.2) Cybernetic consciousness is a consciousness that arises from the fusion of the abilities of biological consciousness and the latest technologies, which has huge (relatively modern) capacities for analyzing and storing information, allowing to satisfy all intellectual needs under any existing environmental conditions and constantly develop the level of knowledge of the laws of matter.
7.3) The degree of self-awareness: most likely, the process of perception of being familiar to us will change, the subject will gradually lose many biological and social qualities of consciousness.
8) Collective consciousness.
8.1) This is the theoretical level of consciousness development, at which individual advanced cybernetic subjects, having organized a single information transmission system, become a collective mind. The individual of a single subject is minimized, humanity as a whole becomes a single organism. Let's imagine cyborgs plowing the expanses of the universe as part of a huge interconnected system of subjects. All the stimuli that get to their sensors are converted into information in a second, analyzed and transmitted millions of light-years around to their comrades. A collective consciousness is gradually being formed in such a community. There is the same knowledge, identical abilities, the same perception, etc. Gradually, such a system will become a collective consciousness with many carriers. It can be assumed that the subjects will explore the universe in tremendous progress, sharing responsibilities like neurons in the human nervous system. A further theoretical level is possible with the complete "dissolution" of the system of subjects in matter, where the entire collective mind becomes a clot of absolute knowledge scattered throughout the entire possible universe. This level of consciousness development is possible only when maximizing the cognitive abilities of subjects.
8.2) Collective consciousness is a consciousness that arises during the formation of a community of knowledge among subjects, the speed of cognition of which is equal to or even exceeds the totality of the capacities of each subject.
8.3) The degree of self-awareness: the general essence of the ideal for each subject.
The "confrontation" of reason and reason
Judging by the development of human consciousness, there is a tendency to reduce the influence of reason on the general processes of consciousness development. So, if in the instinctive consciousness the mind is engaged in most of the processes, then in the civilizational consciousness the mind, due to the increased ability to satisfy the needs of the material system, becomes the predominant part of the mind.
The man of our era almost never succumbs to the many animal reflexes and instincts with which he has lived for many millennia. Now a person is able to refuse bread even when he is hungry, relying on his moral principles. A person is able to suppress many instincts using conscious actions. However, the mind will be the smallest part of the mind only if there is the same level of consumption of the subject's system. Consequently, with the further development of the system of satisfaction of needs, the proportion of reason will continue to increase, and its needs will become the basic needs for man. 
What are the needs of the mind? The need of the mind, first of all, is to improve knowledge about the laws of being and increase the ability of the system of consciousness to acquire this knowledge. Therefore, the maximum development of the mind, and hence consciousness, is absolute objective knowledge – truth.
Truth
Truth is the absolute objective knowledge about the laws and characteristics of matter and being. This truth is achievable only if humanity has the opportunity to study all existing matter and all the patterns that arise in it.
In other words, the purpose of human existence is to satisfy needs, but in satisfying the needs of the material system, evolution has created a new substance – consciousness. Consciousness, which is gradually becoming dominated by reason, has a final need – the need for absolute knowledge.
The goal of humanity is to find the truth by satisfying the needs of the human mind. Only by understanding the whole system of matter will the mind find peace. But is the truth achievable?
In the conditions of ever–evolving matter and an ever-expanding universe, due to the problems of current cosmology, this is too far and difficult a task. And looking back at the stars and seeing the "great silence" of the universe, humanity may have to walk this distance alone.  Who knows what awaits us tomorrow? Exactly, no one. At the same time, everyone should be aware of the need to be fully prepared for the challenges of tomorrow. Otherwise, we will die without knowing the truth.
Conclusion
Based on the theory of the stage-by-stage development of consciousness, we can conclude:
The goal of humanity is to satisfy the needs of subjects and their minds, which are the most complex of them. Only reason is capable of ensuring the long-term survival of our entire civilization and sending us to a point of "safety" at which the extinction of mankind is impossible. 
This can only be ensured by the successful organization of the entire civilization and its spheres of activity. If humanity stops spending a large amount of resources on activities that can and should be avoided (on the common path of progress), then it is necessary to create a proper planning and management system. 
The most incredible challenges may lie ahead of us: from the rise of algorithmic machines to a global war, from the fall of a megameteorite to the absorption of "eternal silence". Without the organization of society for rational long-term development now, the future life of mankind will remain in great doubt.
At the moment, we are not ready to reflect any theoretically possible problems of changing existence, which is why the meaning of existence and work of generations before us is in great doubt. If you don't think about it now, then our great-grandchildren will be able to face the point of no return. At this point, the further development of humanity is impossible.
Do we want our descendants to hate our short-term consumer models? Do we want to live in the universe without a final knowledge of its organization?
The author of this work does not see the meaning of life without further progress of our civilization. And do all people see this meaning, what are they willing to do to achieve it? This is the main question that all of humanity has to answer.
