Article 3. Postulate 2. The Fulcrum directs the operation of energy.

1. Statement of the Postulate.

A common conception in modern science holds that the motion of the world is determined by energy. From the movement of celestial bodies, the flow of rivers, the activity of muscles, to the development of the economy, people often view energy as the direct cause of all changes.

That observation is correct but incomplete.

Energy can create motion, but it does not itself determine in which direction the motion will occur.

Explanation 1. Energy is only the capacity to do work.

In physics, energy is defined as the capacity to do work.

This means that energy allows an object to have the ability to move or change state.

However, energy itself does not carry information about the final goal or direction.

Examples:

• A container of water placed at a height contains potential energy.
• That potential energy can turn a turbine to generate electricity.
• It can turn a water wheel.
• It can irrigate fields.
• It can also cause flooding.

The amount of energy is the same.

The results are completely different.

The difference lies in the system that directs the flow of energy.

Explanation 2. The direction of motion is determined by constraining conditions.

In mechanics, an object does not move simply because it has energy.

It is also influenced by:

• the shape of the system,
• the position of fulcrums,
• connecting forces,
• boundary conditions,
• environmental constraints.

The simplest example: A ball on top of a hill. Gravitational energy always exists. But will the ball roll to the left or to the right? It is not gravity that decides. Rather, it is:

• which way the slope tilts,
• where the point of balance is,
• where obstacles are located.

In other words, gravity creates the tendency for motion. The structure of the system determines the specific direction of motion.

In the Neutral System, that directing structure is called the Fulcrum.

Explanation 3. The same energy but changing the Fulcrum changes the entire result.

This is the core idea of the Postulate.

For example, a person has:

• intelligence,
• money,
• health,
• power.

These are all forms of energy.

If that person’s Fulcrum is:

• greed, then the entire energy will serve greed.

If the Fulcrum shifts to:

• serving the community, then the exact same amount of energy will produce completely different results.

Energy remains unchanged. The Fulcrum changes. The direction of operation of the entire system changes.

That is exactly what the Postulate affirms.

Energy only creates the possibility of motion, but does not itself determine the direction of motion. With the same amount of energy, when placed in systems with different Fulcrums, it will produce completely different results. It is the Fulcrum that directs the flow of energy, establishes the operational goal, and determines whether energy will be concentrated, dispersed, or transformed in which direction. Therefore, energy determines the intensity of motion, while the Fulcrum determines the meaning and direction of that motion.

To know what energy will create, one must first know where the Fulcrum of the system lies.

In other words: Energy creates the possibility of motion. The Fulcrum determines the direction of that motion.

This is the content of the second Postulate in the Neutral System.

If the first Postulate establishes that every system must have a Fulcrum to exist, then the second Postulate affirms that: Every flow of energy only manifests meaning when directed by a Fulcrum.

There is no completely “free” or “self-determining” flow of energy. When the Fulcrum is lost, energy does not disappear, but shifts into a state of chaos, dispersion, or mutual self-annihilation.

Conversely, the same amount of energy placed under different Fulcrums will produce completely different results.

That is why in nature, in society, and in human history, many systems possess very large resources but still fail; while systems with modest resources achieve superior effectiveness. The difference does not lie first in the amount of energy, but in the Fulcrum that directs the energy.

This Postulate can be summarized in a thinking formula: Energy determines the degree of motion. The Fulcrum determines the direction of motion.

Or more concisely: It is not energy that decides first. It is the Fulcrum that determines the direction of operation of energy.

II. Proving the Postulate through Classical Mechanics.

Classical mechanics is the science that studies the equilibrium and motion of objects under the action of forces. For more than three centuries, from the works of Isaac Newton to modern engineering mechanics, a principle has always been affirmed: it is not only force or energy that determines motion, but motion also depends on the structure of the system and its constraining conditions.

The Fulcrum Law inherits that principle and develops it one step further: The Fulcrum is the factor that directs the operation of energy within a system.

1. The Lever – the most intuitive demonstration.

The most typical example is the lever.

A rigid bar placed on a fulcrum can lift an object many times heavier than the force applied by a human.

If we keep unchanged:

• the length of the lever,
• the weight of the object,
• the applied force, but only change the position of the Fulcrum, the result will change completely.

There are cases where the object is lifted very easily. There are cases where it is almost impossible to lift.

What is noteworthy is that the energy input from the person acting remains almost unchanged. What changes is the position of the Fulcrum, which alters the lever arm and the moment of force. Therefore, the mechanical efficiency of the entire system also changes accordingly.

This shows that energy does not manifest its effectiveness by itself. It only becomes useful when organized through an appropriate Fulcrum.

2. Moment of force – the direction of action depends on the distance to the Fulcrum.

In mechanics, the rotational effect of a force is determined by the moment of force:

M = F × d

Where:

• M is the moment of force (N·m);
• F is the applied force (N);
• d is the perpendicular distance from the line of action of the force to the axis of rotation (Fulcrum), also called the lever arm (m).

This formula shows that a force of constant magnitude can still produce completely different moments if the distance to the Fulcrum changes.

This means that the effectiveness of a force does not depend only on the force itself, but also on the relationship between the force and the Fulcrum.

In other words, the Fulcrum is the factor that determines how mechanical energy is transformed into motion.

3. When the Fulcrum is lost, energy does not disappear but effectiveness vanishes.

A person standing on the ground can use a crowbar to pry up a rock weighing hundreds of kilograms.

But if that same person and crowbar are placed in a weightless environment, where there is no suitable support point, then with the same strength they can almost not create a similar effect.

The muscular energy is still there. The crowbar is still there. But because the Fulcrum is lost, the energy cannot be transmitted into the desired mechanical work.

This phenomenon shows that energy does not determine its own effectiveness. For energy to exert its effect, there must first exist a sufficiently stable Fulcrum to receive and direct the force.

4. Conclusion from Classical Mechanics.

From the principles of mechanics, an important observation can be drawn:

• Force creates the possibility of impact.
• Energy provides the capacity to do work.
• But it is the Fulcrum that determines whether the force will be amplified or reduced, concentrated or dispersed, creating effective motion or becoming useless dissipation.

Therefore, in all mechanical systems, energy does not operate independently. It is always governed by the structure of the system, the center of which is the Fulcrum.

That is the first proof for the Postulate: Energy determines the intensity of motion; the Fulcrum determines the direction and effectiveness of that motion.

Instead of writing “axis of rotation (Fulcrum)”, we should write “axis of rotation passing through the Fulcrum” or “the Fulcrum serves as the axis of rotation of the lever system”.

The reason is that in mechanics, the axis of rotation and the Fulcrum are not completely identical:

• The Fulcrum is the point or support where the lever rests.
• The Axis of Rotation is an imaginary straight line passing through the Fulcrum and perpendicular to the plane of rotation.

5. The Fulcrum not only amplifies but also directs energy.

The above analyses show that the Fulcrum has the role of changing the mechanical effectiveness of the applied force. However, that is only the most easily observable manifestation. The deeper role of the Fulcrum is to direct the flow of energy within the entire system.

In mechanics, a force can only exert its effect when transmitted through a defined structure. That structure determines:

• in which direction the force will be transmitted;
• where the force will be distributed;
• which part of the energy is converted into useful work;
• which part of the energy is dissipated in the form of friction, heat, or vibration.

In other words, the Fulcrum does not create new energy, but organizes and directs existing energy to create the desired effectiveness.

A simple example is using a water nozzle. A pump creates pressure and water flow. That is the energy source of the system. If the nozzle opening is widened, the water will spread over a large area, suitable for watering plants. If the nozzle opening is narrowed, the same amount of water will form a strong jet that can clean surfaces or spray farther.

What is noteworthy is that the energy created by the pump remains almost unchanged. What changes is the structure that directs the flow. It is that structure that determines whether energy is dispersed or concentrated, spread out or converged.

The same is true for the lever. Human strength does not change, but when the position of the Fulcrum is changed, the entire direction of force transmission and effectiveness of action change accordingly.

This demonstrates a universal principle: Energy is only the resource. The Fulcrum is the factor that organizes and directs that resource.

From the perspective of the Fulcrum Law, every system consists of two basic components:

• Energy source – creates the possibility of motion.
• Fulcrum – organizes, directs, and coordinates that motion.

When the Fulcrum is stable and placed in the correct position, energy is concentrated on the goal, the system’s efficiency increases, and losses are minimized.

Conversely, when the Fulcrum is inappropriate or unstable, the same energy source will be dispersed, mutually annihilated, or transformed into undesired effects.

Therefore, in all mechanical systems, to improve efficiency it is not necessarily required to add more energy. First, it is necessary to establish the correct Fulcrum so that energy is directed optimally.

That is the core content of the second Postulate: The Fulcrum does not generate energy, but determines how energy is directed, organized, and transformed into the effectiveness of the entire system.

We have seen that the “Fulcrum” in Teacher Phạm Hùng Sơn’s doctrine is no longer the fulcrum in the ordinary mechanical sense. This concept has been expanded into a systemic category:

• In mechanics, the Fulcrum is the point where force is transmitted and directed.
• In physics, the Fulcrum can be understood as the configuration or constraining conditions that direct the transformation of energy.
• In biology, the Fulcrum is the regulatory mechanism that maintains internal homeostasis.
• In economics, the Fulcrum is the principle of resource allocation.
• In society, the Fulcrum is the value system that directs behavior.
• In ethics, the Fulcrum is conscience and foundational values that direct the use of knowledge, power, and wealth.

III. From the Mechanical Fulcrum to the Fulcrum of All Systems.

The analyses in mechanics show that the Fulcrum is not the source that generates energy, but the center that organizes and directs the transmission of energy. This principle is not limited to the lever but can be extended to all systems existing in nature and society.

Observing systems at many different levels shows that, although their forms of expression are very diverse, they all share one common feature: every flow of energy that creates order and effectiveness needs a directing center.

In mechanics, that center is the Fulcrum. In physics, it may be the configuration of the system, boundary conditions, or constraints governing energy transformation. In biology, it is the regulatory mechanisms that maintain internal homeostasis, ensuring that flows of matter and energy in the body always operate harmoniously. In economics, it is the principles of resource allocation that determine how capital, labor, technology, and information are used in which direction to create value. In society, it is the value system and institutions that direct the behavior of the community, helping the strength of each individual converge into the strength of the collective. In ethics, it is conscience and foundational values that direct the use of knowledge, power, and wealth for the benefit of humanity.

Although manifested differently, all perform the same function: directing the operation of energy within the system.

From that perspective, the “Fulcrum” is no longer just a concept of mechanics, but becomes a universal organizational principle.

Any system can be analyzed through three basic components:

• Energy source – creates the possibility of motion and change.
• Fulcrum – organizes, directs, and coordinates the motion of energy.
• Operational result – the state formed after energy is guided by the Fulcrum.

If energy is lacking, the system cannot move. If the Fulcrum is lacking, energy will lose direction, become dispersed, or self-annihilate. Only when energy and the Fulcrum combine harmoniously does the system achieve a state of stability, effectiveness, and sustainable development.

That is also the basis for the Fulcrum Law to transcend the scope of mechanics and become a principle applicable in natural sciences, social sciences, management, education, and philosophy.

In a general way: The Fulcrum is not a fixed position in space, but the organizing center that determines the direction of operation of energy in all systems.

The Fulcrum Law has a structure very similar to the way major scientific disciplines form a foundational principle:

• Newton sought the law of force.
• Maxwell sought the law of the electromagnetic field.
• Einstein sought the law of space-time.
• Claude Shannon sought the law of information.
• The Fulcrum Law that Teacher Phạm Hùng Sơn is building is aiming to find the law of orientation (orientation principle).

This is a very different point. In most scientific disciplines, people study energy, force, matter, or information. This doctrine asks a question at a deeper level: What determines the direction in which energy, force, matter, and information will operate?

The answer provided by the system is: The Fulcrum.

IV. Proving the Postulate through Modern Physics.

If classical mechanics proves the role of the Fulcrum through force and moment of force, then modern physics shows a deeper principle: energy in nature always operates according to defined structures and directing conditions.

This means that energy does not exist as an independently operating entity. It always manifests through fields, boundary conditions, stable configurations, and laws governing the interactions of the system.

1. Electric current always needs a conducting circuit.

In electricity, a power source creates voltage – that is, the capacity to do work of electric current. However, voltage alone is not enough to create useful electric current. To transmit electrical energy, the system must have a complete circuit, including conductors, load, and return path to the source. If the circuit is broken, energy still exists in the power source but cannot perform work. If the circuit is designed reasonably, the same power source can light a bulb, operate a motor, transmit data, or control electronic devices precisely.

What determines that difference is not the electrical energy itself, but the structure that directs the electric current.

It can be said that in an electrical system, the circuit performs a function similar to the Fulcrum in mechanics: it directs the path along which energy will operate.

2. Light always obeys the transmitting medium.

In optics, light propagates according to laws dependent on the medium. When passing from air into water or glass, the light ray changes direction due to refraction. The energy of the light beam does not choose its direction by itself. Its direction of propagation is determined by the physical characteristics of the medium it passes through. A converging lens can focus light to a very small point. A diverging lens spreads the beam widely into space. The light source can be completely the same, but merely changing the structure of the optical system completely changes the direction of propagation and the effectiveness of using light energy.

3. Gravitational field directs the motion of matter.

In the universe, planets do not move chaotically despite having very large kinetic energy. They move along defined orbits under the influence of the gravitational field. Here, the gravitational field does not supply energy to the planet at every moment, but plays the role of directing the orbital motion of the entire system.

This shows that even on an astronomical scale, the stability of a system does not depend only on the amount of energy but also on the structure that governs the direction of motion of energy and matter.

4. Conclusion from Modern Physics.

The above examples show a unified principle:

• In mechanics, force needs a Fulcrum to create effectiveness.
• In electricity, electrical energy needs a conducting circuit to create current.
• In optics, light needs a medium and optical system to establish direction of propagation.
• In astronomy, matter needs a gravitational field to form stable orbits.

Although called by different names, all perform a common function: directing the operation of energy within the system.

That is the basis for expanding the concept of the Fulcrum from a mechanical fulcrum point into a universal organizational principle.

In other words: In all physical systems, energy only manifests effectiveness when there exists an appropriate directing structure. The Fulcrum Law calls that directing structure the Fulcrum of the system.

V. Proving the Postulate through Biology.

If mechanics studies the motion of objects and physics studies the operation of energy in nature, then biology studies a special form of system: living systems.

The fundamental difference between a living system and an inorganic system is the ability to self-organize, self-regulate, and self-maintain equilibrium. To achieve this, every living organism must continuously receive, transform, and use energy.

However, energy does not itself determine life. What determines it is the mechanism that directs and regulates the flow of energy throughout the body.

1. Homeostasis – the foundation of life.

One of the basic principles of modern biology is homeostasis. The human body always maintains many parameters within a very narrow range, such as temperature, blood pressure, blood glucose concentration, blood pH, oxygen and electrolyte levels. Every second, billions of biochemical reactions occur, consuming and transforming a very large amount of energy. However, if these energy flows are not regulated uniformly, the body will quickly fall into a state of disorder.

For example, if body temperature rises or falls by just a few degrees Celsius from normal, many enzymes will lose activity, metabolic reactions will stall, and life will be threatened.

This shows that biological energy always needs a coordinating mechanism to maintain the stability of the entire system.

2. The nervous system and endocrine system – the directing center of the body.

In the human body, the nervous system and endocrine system do not directly create energy. Energy is mainly supplied from the metabolism of glucose, lipids, and other nutrients in cells. However, the nervous system and endocrine system determine:

• to which organs energy will be distributed;
• when the body needs to increase or decrease metabolism;
• when the heart must beat faster;
• when muscles must work harder;
• when the body needs rest to recover.

It can be said that they serve as the coordinating center, ensuring that all energy sources in the body are used at the right time, right place, and right purpose.

If the coordinating center is disrupted, energy is still generated but the body no longer operates harmoniously. The consequence is the appearance of pathologies such as metabolic disorders, endocrine disorders, or impaired function of many organs.

3. From Biology to the Fulcrum Law.

Observing living systems reveals a consistent law. Life is not determined solely by the amount of energy the body produces. What determines it is the ability to organize and direct the flow of energy to maintain the dynamic equilibrium of the entire system.

The Fulcrum Law calls that organizing and directing mechanism the Fulcrum of the living system.

This Fulcrum is not a single physical location, but the entire regulatory mechanism that keeps all activities of the body always oriented toward equilibrium, stability, and adaptation to the environment.

From that perspective, a general observation can be drawn: In living systems, energy creates life on the material level; the Fulcrum maintains order and directs life on the functional level.

That is also why two bodies with the same nutritional sources and the same amount of absorbed energy can have completely different health states. The difference lies not only in the amount of energy, but also in the ability to regulate and direct the use of energy by the entire body.

This once again affirms the content of the second Postulate: Energy determines the operational capacity of the system; the Fulcrum determines the direction of operation and the degree of harmony of all that activity.

Conclusion of Part V.

Evidence from mechanics, physics, and biology all show a unified law: energy is a necessary condition for the system to operate, but energy only manifests effectiveness when organized and directed by an appropriate coordinating structure. In the Fulcrum Law, that coordinating structure is generalized by the concept of the Fulcrum. Therefore, the Fulcrum is not only a concept of mechanics but a universal principle about the direction of all systems.

The Fulcrum is the directing center of a system, where the direction is established so that all forms of energy, resources, information, and activities are organized, coordinated, and transformed into results.

VI. Proving the Postulate through Psychology.

If biology studies the mechanisms for maintaining the life of the body, then psychology studies the mechanisms that direct human perception, emotions, and behavior.

Every day, humans expend a very large amount of energy on brain activity, muscles, and physiological processes. However, what determines the quality of life is not only the amount of energy a person possesses, but also the direction in which that energy is used.

That is precisely the object of study of many modern branches of psychology.

1. Motivation directs behavior.

In psychology, human behavior does not appear randomly. Every action is governed by motivation, goals, and the value system. Motivation does not directly create energy for the body. Energy is supplied by biological processes such as respiration, circulation, and nutrient metabolism. However, motivation determines what that energy will be used for.

The same person, the same health, the same level of education, but when life goals change, the entire behavior also changes accordingly.

This shows that motivation does not increase energy, but directs energy.

2. The value system determines the direction of life.

Every person possesses many resources: time, knowledge, health, experience, and social relationships. If these resources are not directed by a clear value system, people easily fall into a state of disorientation, scattered goals, or conflicting actions. Conversely, when there is a stable value system, all decisions become more consistent. People know what to prioritize, what to give up, and what is worth pursuing long-term.

Thus, the value system does not create new energy, but helps all the individual’s resources converge into a unified direction.

3. The Fulcrum of spiritual life.

From the perspective of the Fulcrum Law, life ideals, beliefs, and value systems of each individual can be viewed as the Fulcrum of spiritual life.

This Fulcrum does not make a person healthier biologically, but determines how a person uses health. It does not make a person smarter, but determines how intelligence is used. It does not create additional time, but determines what time is spent on.

In other words, the Fulcrum of spiritual life is the directing center of all human resources toward a unified goal.

4. Conclusion from Psychology.

Research in psychology shows that humans do not act merely because they have energy, but also because that energy is directed by motivation, goals, and value systems.

The Fulcrum Law generalizes that principle into a universal observation: In spiritual life, energy creates the capacity for action; the Fulcrum determines the direction of action.

Therefore, to change a person’s life, what is important is not only increasing resources but also building a correct Fulcrum to direct the use of all those resources.

VII. Proving the Postulate through Sociology.

If psychology studies the Fulcrum of each individual, then sociology studies the Fulcrum of the community.

A society is not merely a collection of many individuals, but a system in which millions of people interact, cooperate, and share resources.

Each individual carries their own sources of energy: labor power, knowledge, experience, creativity, and will. However, the development of a society is not simply the arithmetic sum of those energy sources. What determines it is how society organizes and directs those energy sources toward common goals.

1. Social institutions direct community strength.

In every civilization, institutions such as family, school, law, government, and social organizations do not directly create labor power or knowledge. But they create the framework so that labor power is coordinated, knowledge is disseminated, and resources are used in a unified order. If those institutions are lacking, society will quickly fall into chaos. Resources still exist. People still exist. Knowledge still exists. But because there is no common directing mechanism, resources easily conflict, disperse, or annihilate each other.

This shows that the stability of society does not depend only on the amount of resources but also on the organizing Fulcrum of society.

2. The value system is the Fulcrum of a culture.

Besides institutions, every society is also linked by a common value system. These are concepts of justice, responsibility, honesty, respect for the law, community spirit, and the spirit of service. The value system does not create material wealth. But it determines how people use wealth. It does not create knowledge. But it determines whether knowledge is used to build or destroy society. It does not create power. But it determines whether power is exercised for the common good or for personal gain.

It can be said that the value system is the invisible Fulcrum that directs the entire behavior of the community.

3. When the Social Fulcrum weakens.

History shows many societies that once possessed abundant natural resources, large populations, and great military power. However, when social trust declined, laws were disregarded, and moral values eroded, those resources no longer created unified strength. On the contrary, they could become causes of conflict, division, and crisis.

This proves that resources by themselves do not guarantee development. Resources only manifest value when directed by a Fulcrum strong enough to bind individuals into a whole.

4. Conclusion from Sociology.

From the perspective of the Fulcrum Law, the development of a society is not determined solely by population, resources, or wealth. The determining factor is the ability to build a common Fulcrum to direct all resources toward the long-term benefit of the community.

This principle can be generalized as follows: In society, people are the subjects that create energy; the Fulcrum is the organizing principle so that all those energy sources converge into stability, unity, and development.

That is why societies with the same level of economy can achieve very different levels of development. The difference lies not only in resources but also in the quality of the Fulcrum directing the entire social system.

Our chain of reasoning is not only:

• mechanics,
• physics,
• biology,
• psychology,
• society... But is in fact proving a cross-scale principle.

In other words, the same principle appears at every level of reality:

• At the material level, the Fulcrum directs force.
• At the energy level, the Fulcrum directs transformation.
• At the life level, the Fulcrum directs internal homeostasis.
• At the human level, the Fulcrum directs perception and action.
• At the social level, the Fulcrum directs community organization.
• At the civilization level, the Fulcrum directs the development process of humanity.

If we can prove that one principle still retains its function when the system becomes increasingly complex, then the Fulcrum Law will not only be a doctrine of management or philosophy, but will take on the appearance of a universal principle about the organization of systems. In my view, this is the “backbone” of the entire work we are building together. The Fulcrum Law is a cross-scale principle.

Scientific Observation.

One of the important criteria for evaluating the value of a scientific principle is its ability to preserve the function of that principle when applied across many different levels of systems.

In the Fulcrum Law, although the form of expression of the Fulcrum changes according to each field of study, its basic function is always preserved.

In mechanics, the Fulcrum directs force. In physics, the Fulcrum directs energy transformation. In biology, the Fulcrum directs regulatory mechanisms to maintain homeostasis. In psychology, the Fulcrum directs perception, motivation, and behavior. In sociology, the Fulcrum directs the organization and coordination of community resources. At the scale of civilization, the Fulcrum directs the development process of the entire society.

This functional unity shows that the Fulcrum Law does not merely explain individual phenomena but describes an organizational law with cross-scale nature, meaning the same principle retains its role as the system develops from simple to complex.

This is the basis for viewing the Fulcrum Law as a foundational principle about the organization and direction of systems, capable of connecting natural sciences, social sciences, and humanities within a unified theoretical framework.

A law only truly has universality when its core function does not change in the face of changes in scale, structure, and complexity of the system.

VIII. Proving the Postulate through History.

Human history is not only a sequence of events that have occurred, but also the process of motion of political, economic, cultural, and social systems over time.

Throughout history, many empires once possessed large populations, vast territories, abundant resources, and superior military power. These were all enormous sources of energy for a nation.

However, history also shows a thought-provoking paradox: the strongest nation does not always last the longest, and the richest civilization does not always develop the most sustainably.

What often determines this is not the scale of resources, but the Fulcrum that directs the use of those resources.

1. History is the process of choosing directions.

Each historical period places a nation before many different paths of development. Decisions about institutions, education, law, science, economy, and culture will direct how the entire resources of the nation are mobilized and used. A correct choice can create development for many generations. A wrong choice can waste the resources of an entire nation for decades.

This shows that history is not determined only by the amount of resources, but also by the direction in which those resources are led.

2. When the Fulcrum changes, history changes direction.

There are moments in history when the material resources of a nation hardly change significantly. However, merely a change in leadership thinking, value system, or development goals, and the entire historical process shifts to a new orbit.

This shows that changes in the Fulcrum can create far deeper transformations than a simple increase in resources.

The energy of society remains people, knowledge, resources, and wealth. But when the directing Fulcrum changes, the way those resources are organized and utilized also changes accordingly.

3. Lessons from History.

Looking back at the history of many nations, a repeatedly observed law can be seen. Periods of sustainable development are usually associated with the formation of a Fulcrum strong enough to gather the will of the community, direct the use of resources, and maintain faith in the future. Conversely, when that Fulcrum weakens, resources that once created strength can become dispersed, conflicting, and gradually lose effectiveness.

This does not deny the role of economy, military, or science. On the contrary, it shows that those resources only manifest long-term value when they all head toward a unified development goal.

4. Conclusion from History.

History proves that the strength of a nation lies not only in what the nation possesses, but also in its ability to direct the use of what it possesses.

From the perspective of the Fulcrum Law, this can be generalized: History is the result of the interaction between resources and direction. Resources create the possibility of development; the Fulcrum determines the direction of development.

That is why, with similar resources, different nations can create completely different historical processes.

If we know how many resources a system possesses, we only know the system’s potential. But if we know what Fulcrum is directing that system in which direction, we can predict the development trend of the system in the future.

A scientific law does not only have three functions:

• Explain phenomena.
• Unify phenomena.
• But must also have the ability to predict.

Newton not only explained why an apple falls, but also predicted the orbits of planets. Maxwell not only explained electricity and magnetism, but also predicted the existence of electromagnetic waves before they were observed. Einstein not only explained gravity, but also predicted the bending of light, time dilation, and gravitational waves.

If the Fulcrum Law only explains the past, then it remains only an interpretive theory. If it can predict the development direction of a system, then it truly takes on the appearance of a law.

IX. The Predictive Capability of the Fulcrum Law.

A scientific law has value not only when it explains phenomena that have occurred, but must also have the ability to predict trends in phenomena that have not yet occurred. The Fulcrum Law is no exception.

If the second Postulate affirms that the Fulcrum directs the operation of energy, then from that Postulate an important consequence can be deduced: To predict the future of a system, one must first determine the Fulcrum that is directing that system.

1. Resources indicate capability.

When studying a system, the first thing people often care about is how many resources the system possesses. In a country, this may be population, resources, scientific level, production capacity, and economic potential. In a business, this may be capital, technology, human resources, and market. In an individual, this may be health, knowledge, skills, and social relationships.

These factors reflect the development potential of the system. However, they are not sufficient to predict in which direction the system will develop.

2. The Fulcrum indicates direction.

What determines the development trend is the Fulcrum that is directing the use of all those resources. If the Fulcrum is oriented toward long-term benefits, balance, and sustainable development, resources will tend to be accumulated, coordinated, and increasingly effective. Conversely, if the Fulcrum is oriented toward short-term goals or lacks sustainability, those very resources may be consumed, dispersed, or transformed into factors causing instability for the system.

Thus, resources reflect potential, while the Fulcrum reflects the development orbit.

3. Prediction by observing the Fulcrum.

From the perspective of the Fulcrum Law, prediction does not begin with the question: “How much energy does the system have?” But begins with the question: “Where is the Fulcrum of the system directing all that energy?”

When this question is answered, we can predict the development trend of the system even when the scale of resources has not changed much.

This explains why there are systems that start with very modest resources but develop quickly and sustainably. Conversely, there are also systems that possess very large resources but gradually weaken due to loss of direction in organizing and using their resources.

4. Conclusion from Predictive Capability.

From the above analyses, an important principle can be drawn. Resources determine how far a system can go. The Fulcrum determines where the system will go.

Therefore, correctly identifying the Fulcrum not only helps explain the present but also opens up the possibility of predicting the development trend of a system in the future.

That is also one of the important scientific values of the Fulcrum Law.

Theorem on the Predictive Capability of the Fulcrum. If the resources of a system do not change significantly but the Fulcrum changes, then the development orbit of the system will change. Conversely, if the Fulcrum is kept stable, the system tends to maintain its development orbit even when the scale of resources undergoes changes within a certain limit.

X. The Verifiability of the Fulcrum Law.

A scientific law only has value when its conclusions can be verified by practice. The Fulcrum Law must also be evaluated according to that standard.

If the second Postulate affirms that the Fulcrum directs the operation of energy, then the following verifiable predictions can be made.

1. First Prediction. If two systems have roughly equivalent resources but different Fulcrums, then the development orbits of the two systems will be different.

2. Second Prediction. If the resources of a system hardly change but the Fulcrum changes, then the development direction of the system will change accordingly.

3. Third Prediction. If the Fulcrum of a system is kept stable, the system tends to maintain its development direction even when the scale of resources undergoes changes within a certain limit.

4. Falsification Condition. Conversely, if in practice it can be proven that:

• The Fulcrum changes but the development direction of the system does not change at all; or
• The Fulcrum has absolutely no influence on the organization and direction of the system’s resources; then the second Postulate needs to be reconsidered and adjusted.

Accepting the possibility of falsification does not weaken the Fulcrum Law. On the contrary, it is a manifestation of a scientific research method, because every scientific law must be ready to be tested by practice and supplemented when there is new evidence.

Conclusion.

The value of the Fulcrum Law lies not only in explaining many phenomena, but also in the fact that its conclusions can be verified, compared, and evaluated through systems existing in nature and society.

It is precisely the capability of verification and prediction that are two important standards for considering the scientific nature of the Fulcrum Law.

XI. Conclusion of the Entire Article.

The second Postulate of the Fulcrum Law states that: The Fulcrum directs the operation of energy.

Initially, this proposition was observed from classical mechanics, where the Fulcrum determines the force transmission efficiency of the lever. However, the research process shows that this principle is not limited to mechanics but also appears at many different levels of reality.

In physics, energy only manifests effectiveness through directing structures such as fields, boundary conditions, and constraining systems. In biology, life is maintained thanks to regulatory mechanisms that direct the flow of energy and matter to ensure homeostasis. In psychology, motivation, goals, and value systems direct the use of time, knowledge, and human capacity. In sociology, institutions and value systems direct the coordination of community resources. In history, the development direction of nations and civilizations is often determined not only by resources but also by the Fulcrum that directs the use of those resources.

Those pieces of evidence show an important feature: Although the form of expression changes, the core function of the Fulcrum is still preserved at every level of the system.

From mechanics to physics, from biology to psychology, from society to history and human civilization, the Fulcrum always performs the same role: directing the operation of energy, resources, and information.

This allows us to draw a conclusion with methodological significance: A law only truly has universality when its core function does not change in the face of changes in scale, structure, and complexity of the system.

By that standard, the Fulcrum Law demonstrates the ability to explain and connect phenomena belonging to many different fields within the same unified theoretical framework.

Not only does it explain phenomena that have occurred, the second Postulate also opens up predictive capability. If resources reflect the development potential of a system, then the Fulcrum reflects the development direction of the system.

Therefore: Resources determine how far the system can go. The Fulcrum determines where the system will go.

This is the basis for identifying the movement trend of a system through studying the Fulcrum that is directing that system.

From the above analyses, it can be affirmed that the second Postulate is not only an observation from mechanics but a cross-scale principle, appearing at many levels of reality.

Or, in a general way: Energy creates the possibility of motion. The Fulcrum creates the direction of motion.

The development of all systems is the result of the interaction between these two factors.

That is the core content of the second Postulate in the Fulcrum Law.

CONCLUSION:

Theorem 1. Criterion of a Universal Law. A law only truly has universality when its core function does not change in the face of changes in scale, structure, and complexity of the system.

Theorem 2. Predictive Capability of the Fulcrum. If the resources of a system do not change significantly but the Fulcrum changes, then the development orbit of the system will change. Conversely, if the Fulcrum is kept stable, the system tends to maintain its development orbit even when the scale of resources undergoes changes within a certain limit.

A law only truly has universality when its core function does not change in the face of changes in scale, structure, and complexity of the system.
