Introduction

Sometimes, a piece of music becomes the gateway to philosophy.

It possesses no words and makes no demands; it simply exists, much like a space. Most music we listen to in our daily lives attempts to convey something. Lyrics tell a story, melodies evoke emotion, and rhythms invite the body to move. Historically, music has functioned essentially as a medium for communication. Yet, on very rare occasions, there exists music that completely transcends this framework. It says nothing. It has no need to. It is simply there.

The music of Cornelius was precisely such an existence.

When I first encountered his work, I felt a certain sense of disquiet. I could not determine whether it was pleasant or tedious, moving or sterile. I was supposed to be listening to music, yet the very sensation of listening grew ambiguous. The sounds were certainly flowing. Yet, they were not flowing to stir my emotions. The sound was creating a space around me. Or, to be more precise, it was not that I was inside the sound, but rather that the sound and I occupied the same environment.

His work attempts to tell us nothing. It does not fan the flames of emotion, nor does it present a message. Nevertheless, as you listen, the very premises of the world begin to quietly shift. You are supposed to be listening to music, yet before you know it, you realize that you are an "existence within an environment." I am not listening to the sound; I am in a single place along with it. This shift in perception became the starting point for all my thoughts.

What began there was not emotion, but contemplation.

This text is a record of that contemplation. Taking the music of Cornelius as a starting point, it traces a genealogy of intellect that came into view from there. It is something that should be called environmental intelligence. Traversing various domains—music, technology, ethics, civilization—there exists an intellect that consistently points in the same direction. This book is an attempt to trace that genealogy as carefully as possible and explore what lies beyond it.

I would like to briefly touch upon the structure of this book. Part I discusses the existence of Cornelius itself and the unique qualities of his music. Part II traces the genealogy to which he belongs—from YMO through Flipper's Guitar to Cornelius—and follows how environmental intelligence was formed. Part III discusses the relationship between technology and ethics, and how the concept of an OS connects with environmental intelligence. Part IV reflects on the solitude brought about by environmental intelligence, and the quiet joy that is inseparable from it. Part V shows that the philosophy of minimization lies at the core of environmental intelligence. Finally, the concluding chapter connects these reflections to civilizational theory, presenting a vision of civilization as stillness.

I recommend that readers listen to Cornelius's music while reading this book. His works—especially "Fantasma," "Point," and his recent output—embody the ideas discussed herein in a form that transcends words. When music and text resonate, understanding runs deeper.

Part I: The Origins of Environmental Intelligence

1. The Existence of Cornelius

Cornelius is less a musician and more a "designer of perception."

This expression is by no means an exaggeration. When we listen to his work, we experience something that cannot be fully captured in the ordinary mode of music appreciation. In typical pop music, sound is structured by melody, rhythm, and harmony. We listen to the song, the track, and the artist's expression. Sound functions as a medium that carries meaning.

Yet, in the work of Cornelius, sound appears not as melody or rhythm, but as a component of space.

Listening to albums like "Fantasma" (1997) or "Point" (2001) makes this sensation easy to grasp. Sound moves forward and backward. One sound is placed close, another far away. Beyond just the left and right of stereo, there is depth, and location along the time axis—sounds are arranged in a three-dimensional, indeed four-dimensional space. Time stretches and contracts. One moment is drawn out, another compressed. And quietness functions not as mere silence, but as a distinct layer. Quietness is also a kind of sound.

Within it, humans are not at the center.

This is the decisively important point. Most music is designed with the listener at the center. The resonance of emotion, the reaction of the body, the summoning of memory—all are predicated on occurring within the listener. But in Cornelius's work, the listener is not the center, but part of the environment. The music is not about listening to "someone's expression," but exists as an environment. We are inside that environment. We are not listening to the environment; we are simply with it.

At this point, his work already transcends the context of pop music.

Keigo Oyamada—the real name of Cornelius—emerged on the Japanese pop scene in the early 1990s as a member of Flipper's Guitar. His music at the time strongly reflected the influence of British indie pop and shoegaze. However, Cornelius as a solo project fundamentally shifted this direction. Lyrics diminished, melodies fragmented, and acoustics themselves became the protagonist. What he pursued was not the communication of emotion through music, but the design of the auditory environment itself.

Supplement: Perception and Design

Let us delve a little deeper into the meaning of this term: designer of perception.

An architect designs space. He considers how people will experience the space, deciding on the walls, the floors, and how light enters. Consequently, one space holds a calm atmosphere, while another is filled with vitality. The architect does not directly manipulate people's emotions. He designs the conditions in which people are placed. And through those conditions, people's experiences shift.

Cornelius is an architect of auditory space. He designs the acoustic environment in which the listener is situated. The placement of sound, the flow of time, the use of quietness—these, like walls and light in architecture, are the elements that shape experience. His "design" is superior because, rather than imposing a specific emotion on the listener, it leaves room for the listener to construct their own experience.

Ordinarily, we are not conscious of how we perceive the world. Seeing, hearing, touching—these acts feel as though they occur naturally and self-evidently. Yet in reality, our perception is defined by countless conditions. The amount of light, the quality of sound, the breadth of space, the flow of time—these are all factors that determine how we experience the world. Usually, we accept these conditions as "givens" and live our lives upon them.

A designer of perception is one who intentionally manipulates these conditions. He does not add new information; he changes the existing conditions of perception. As a result, the same world looks and sounds different. Cornelius's music resets the conditions of hearing. After listening to his work, you may notice for a while that the way the world's sounds are heard has changed. This is not because he "taught" you something. It is because he rewrote the auditory OS, if only slightly.

2. From Music to Environment

Two Functions of Music

Historically, music has had two primary functions. One is its function as a medium of communication. Music communicates emotions and ideas. Lyrics tell a story, and melodies express feelings. The other is its function as a medium for ritual and community cohesion. Music gathers people, moves them to the same rhythm, and creates a sense of unity as a group. In both functions, music operates "between humans." From human to human, or within a human group, music carries meaning.

Yet, there is a third possibility for music. It is the possibility of functioning at a dimension beyond the human. Music does not communicate human emotions, but structures the very "place" in which humans are situated. Music does not carry meaning between humans, but exists as part of the environment that includes them. Cornelius pursued this possibility to the limit.

Most music is structured around human emotion.

This fact is clear when looking back at the history of music. From ancient shamanic music to religious music, classical music, and contemporary pop, music has always been deeply bound to the human interior. Lyrics convey meaning, melodies create empathy, and rhythms move the body. Music expresses joy, sadness, anger, and longing—evoking those same emotions in the listener. In other words, music is an expression that deals with "the inside of the human."

This framework is extremely powerful. When we listen to music, we unconsciously search for "what this song is trying to convey" and "how we should feel." If there are lyrics, we interpret their meaning; if there is a melody, we relive that emotion. Music appreciation is, essentially, a process of resonance with the interiority of another.

But Cornelius's work moves in the opposite direction.

His music does not stimulate the inside of the human; it changes the "conditions" in which the human is placed. Rather than stirring emotions, it changes the very soil from which emotions grow. This represents a fundamental shift in the role of music.

Let us clarify the concept of environment a little further.

We are always within some environment. The physical environment—room temperature, the amount of light, the quality of sound. The social environment—the people around us, institutions, expectations. The informational environment—flowing news, social media, advertisements. These environments define our thoughts, emotions, and actions. Concentrating is hard in a hot room. Restlessness occurs in a noisy place. Excessive information dulls judgment. The environment is the precondition for what we feel and what we think.

Cornelius's music designs the auditory environment. He does not act directly on the listener's emotions; he changes the acoustic conditions in which the listener is situated. As a result, emotions and thoughts shift. It is closer to environmental design than music.

This distinction is also important in practice.

Music that acts directly on emotions often has a manipulative character. Raising the tempo to invite excitement, evoking emotion at the chorus, providing catharsis at the drop—these techniques aim to "guide" the listener in a certain direction. This is not necessarily bad. However, the approach of designing an environment is different. The designer of an environment does not decide where the listener goes. They simply prepare the conditions for the listener to feel and think freely. The resulting emotions and thoughts belong to the listener.

This is why Cornelius's work elicits completely different reactions depending on the listener. Some feel a meditative calmness, some sense a slight anxiety, while others find it simply pleasant. He does not impose a specific emotion. What he provides is the place where emotion is born.

3. The OS of Perception

An OS is usually not conscious.

When using a computer, we focus on the applications on the screen. We edit documents, browse the web, and send emails. We hardly notice that behind them, the operating system is managing memory, scheduling processes, and controlling input and output. The OS provides the preconditions for all actions. Yet, it does not rise to the surface of consciousness.

The user sees the applications appearing on the screen, but remains unaware of the conditions operating behind them. And as long as the OS functions normally, there is no need to notice. An OS is only conscious when it fails, or when it performs some unexpected behavior.

Cornelius's work resides in exactly that position.

Rather than asserting something, he quietly resets the conditions of the listener's perception. The flow of time, the sense of space, the way sound exists—these correspond to the OS of how we experience the world. We normally take it as self-evident that time flows at a constant speed, space extends in three dimensions, and sound is the vibration of air. Yet these "self-evident" assumptions are, in fact, variable.

While listening to his work, there are moments when the sense of time changes. In some parts, time seems stretched, flowing at a leisurely pace. In another, multiple timelines feel overlaid. The same is true of space. The sensation of sounds placed not just left and right, but front and back, up and down. The feeling of being surrounded by sound. The way sound exists also changes. Sound is felt not as "something emitted from something," but as "something that is there."

When those elements change minutely, one notices for the first time. The world is not a given, but established upon designed conditions.

This realization transcends the domain of music. What we call "reality" is actually established upon countless perceptual, cognitive, and social conditions. For a long time, those conditions have been accepted as "natural" and "unchangeable." Yet, conditions can be designed. And the intellect that designs those conditions—that is environmental intelligence.

The metaphor of the perceptual OS carries important implications in a technological context as well. Today, we interact with countless applications through smartphones and computers. Yet, the foundation upon which those applications run—the OS, networks, algorithms—remains outside our attention. And how they define our experience is also often invisible.

Cornelius's music makes us aware of the existence of this hidden layer at the level of perception. Listening to his work is an experience that temporarily visualizes what kind of "OS" we are experiencing the world upon.

4. The Design of Stillness

What makes Cornelius's work unique is that it places "stillness" at its center.

Modern pop music often competes in sound density. Tracks are packed with countless elements, beats are intricately carved, and sounds change constantly. Keeping the listener's attention and preventing boredom is emphasized. Stillness is instead avoided. Silence might make the listener anxious.

Yet, in Cornelius's work, it is the scarcity of sound, not its abundance, that determines quality. Not assertion, but margins create meaning. Many of his songs have surprisingly few sounds. A single sound rings out for a long time, silence follows, and then the next sound appears. The "empty" time between them is, in fact, the most important part.

Stillness is not a state of nothingness.

This point must not be misunderstood. Stillness is not mere silence or blankness. It is a state where all elements are in harmony. Even if sounds suddenly stop in a noisy room, that is not stillness. Rather, by contrast, the preceding noise is more strongly felt. True stillness is a state where unnecessary things have been removed, leaving only what is required. It is a fulfilling emptiness.

This philosophy deeply overlaps with the concept of "ma" (the space between) in Japanese culture.

Noh theater, tea ceremony, haiku, calligraphy—in traditional Japanese arts, "ma" is a decisively important concept. On the Noh stage, there is a long silence between movements. In that silence, the audience confronts their own interiority. In the tea ceremony, intentional pauses are built into the steps of preparing a bowl of tea. Haiku, through its extreme seventeen-syllable format, leaves a vast margin for the reader's imagination. In calligraphy, the blank space of the paper—the margin—holds equal significance to the inked portions.

"Ma" is not empty time or space. It is a place where meaning is born and resonance occurs. In Noh, the actor's movement sinks into the audience's interior during the pause. In the haiku's margin, the reader supplies the image. "Ma" demands the participation of the receiver. And through that participation, the work is completed.

Stillness in Cornelius's music serves a similar function. When he strips away sounds, he is causing the listener to "do" something. The listener sharpens their own hearing in the stillness. Waiting for the next sound, feeling the relationship between sounds, becoming aware of one's own existence. Stillness is an environment that enables the active participation of the listener.

And that is also the essence of the intellect that designs environments.

A good environment is not one packed with many things. It is an environment where necessary things are appropriately placed and unnecessary things are removed. In a noisy space, thoughts scatter. In an information-overloaded environment, judgment dulls. Stillness—physical, informational, psychological—is the condition for humans to exercise their inherent abilities.

Environmental intelligence is the intellect that designs and maintains this stillness. It is not an intellect that adds something, but one that strips things away. And through that stripping away, the essence appears.

Supplement: The Aesthetics of "Ma" and the Modern Era

The aesthetics of "ma" in Japanese tradition are beginning to hold new meaning in contemporary information environments. We live in an environment where we are constantly connected, with information always flowing in. Smartphones fill the gaps in our time. Social media refuses to allow silence. From our lives, "ma"—empty time, space with no input—is being lost.

The stillness provided by Cornelius's music temporarily recovers this lost "ma." When listening to his work, we are not "consuming" something. Rather, we are liberated from consumption. Sound flows, but not to rob us of our attention. Between sound and silence, we gain the room to confront our own interiority.

This is why environmental intelligence emphasizes "ma." "Ma" is not a mere blank. It is an indispensable condition for humans to face themselves and think about what is truly important.

Part II: Genealogy

5. YMO as the Starting Point

The origin of this environmental intelligence traces back to the 1970s.

In 1978, Yellow Magic Orchestra—YMO—made their debut. Composed of Yukihiro Takahashi, Haruomi Hosono, and Ryuichi Sakamoto, this trio shocked not only Japan but the entire world with electronic music utilizing synthesizers and computers. They are often discussed as "pioneers of electronic music." Certainly, the technology they used—the Roland MC-8, Prophet-5, and state-of-the-art sequencers of the time—fundamentally changed the nature of music production.

Yet, their true innovation lay not in the use of electronic sounds.

Electronic music itself had existed prior to YMO. Kraftwerk in Germany, Jean-Michel Jarre in France, and Isao Tomita in Japan—there were numerous pioneers using electronic instruments.

Comparing YMO with Kraftwerk is instructive in understanding YMO's uniqueness. Kraftwerk also used mechanical rhythms and synthesizer sounds to create music distanced from human physicality. Yet, Kraftwerk's music carried a certain utopian vision of the future. The concept of "man-machine" expressed a longing for the fusion of human and machine. On the other hand, YMO's music lacks such a clear future vision. Their music presents the current environment as it is. It depicts the here and now, surrounded by technology, neither optimistically nor pessimistically, but as it is. This difference in attitude makes YMO a distinct existence.

YMO's innovation was not in the use of technology itself, but in how it was used.

What they did was shift the subject of music from the human to the environment.

In conventional rock and pop, music was deeply bound to human physicality. Drums were the movement of hands and feet, guitar was the movement of fingers, singing was the vibration of vocal cords—music existed as an extension of the human body. But in YMO's music, the human body recedes from the foreground. The sounds generated by synthesizers are born of a logic different from the movement of human hands. The rhythms carved by sequencers are unrelated to human breath or heartbeat. Mechanical sounds are cold, repetition is inorganic, and human presence grows faint.

There, music exists not as human expression, but as atmosphere.

Listening to tracks like "Rydeen" or "Technopolis" makes this sensation understandable. These songs certainly include human elements—melody, rhythm, a certain humor. Yet overall, the music gives the impression that "something is operating" rather than "someone is performing." Like factory machinery or urban infrastructure, the music exists as part of the environment.

This shift was also deeply bound to the context of Japanese society at the time. In the late 1970s, at the peak of high economic growth, urbanization and technological advancement were progressing rapidly in Japan. Skyscrapers rose in Tokyo, home appliances spread to households, and people's lives became surrounded by machines and electronic devices. YMO's music translated this new environment—urban life surrounded by technology—directly into sound. Their music was neither optimism for the future nor nostalgia; it presented the current environment as it was. It contained a celebration of technology, and at the same time, a sense of disquiet toward it.

The song title "Technopolis" symbolizes this ambivalence. A city of technology—it is an image of a hopeful future, and simultaneously a cold environment where humans are surrounded by machines. YMO etched this ambivalence into their music. They did not reject technology. Yet, they did not praise it uncritically either. They constantly threw questions at the relationship between technology and humans.

This ambivalence is the starting point of environmental intelligence. Environmental intelligence does not simply affirm or deny technology. Technology structures our environment. And it constantly questions that manner of structuring—how technology affects human experience. This is the attitude shared across the genealogy since YMO.

6. Flipper's Guitar as a Turning Point

The Japanese Context of the 1990s

The Japan of the early 1990s, when Flipper's Guitar appeared, was filled with a unique atmosphere. The bubble economy had collapsed, and the narrative of past "success" became doubtful. On the other hand, foreign culture—especially British indie pop—exerted a strong influence on the younger generation. The Stone Roses, Happy Mondays, and the Madchester sound showed new possibilities to the Japanese music scene. Within this context, Flipper's Guitar brought a decisive shift to Japanese pop music.

Their innovation was not simply importing foreign sounds. They reevaluated the very act of making music from a new perspective. What is originality? What is citation? Can something new be born by combining existing elements? These questions lay behind their music.

Flipper's Guitar connected postmodern intelligence to this environmental intelligence.

Formed in 1990 by Kenji Ozawa and Keigo Oyamada, Flipper's Guitar occupies a unique position in Japanese pop music history. Their music strongly reflected the influence of British indie pop—especially The Pastels, The Stone Roses, and PWL-style productions. Yet, it was not mere imitation. They "cited" and "collaged" such music, reconstructing it with a light irony.

Citation, collage, light irony—these techniques are characteristic of postmodern art.

In postmodernism, the pursuit of originality is a subject of skepticism. Everything already exists. Rather than making something new, one combines, cites, and parodies the existing. Meaning is not fixed, but fluid depending on context. Flipper's Guitar's music expressed this sensation in the form of pop music.

Their work showed that the world is a gathering of fragments.

In songs like "The Camera! Camera! Camera!" or "Friends Again," various musical elements—beats, melodies, samples—are arranged as fragments, gently connected. Rather than a grand narrative unfolding, fragments are juxtaposed, and the listener interprets their relationship. There, grand narratives do not hold, and meaning remains fluid.

At this point, Japanese pop music met a decisive turning point.

Japanese pop of the 1980s still placed value on the pursuit of the "original." Artists expressed their own worldview, and listeners immersed themselves in that world. But after Flipper's Guitar, music shifted from the "expression of a worldview" to the "arrangement of fragments of the world." Music no longer tells a single cohesive story. It is a collection of fragments, an open structure that leaves room for the listener's interpretation.

Keigo Oyamada—later Cornelius—passed through this experience of Flipper's Guitar and moved toward environmental intelligence. What he learned was the possibility of music "constructing an environment" rather than "conveying meaning." And that environment was fragmentary, fluid, and demanded the participation of the listener.

7. Intellect of Meaning and Intellect of Environment

After the disbandment of Flipper's Guitar, two intellects clearly diverged.

Following their split in 1991, Kenji Ozawa and Keigo Oyamada proceeded in completely different directions. This divergence is not a mere difference in musical style. It represents a fundamental difference in the type of intelligence.

Kenji Ozawa deepened his words and explored the world of meaning.

In his solo works—especially "Life" (1994) and subsequent releases—lyrics play a decisively important role. His lyrics, while using everyday language, throw out philosophical questions. What is life? What is correctness? How should we live? Through words, he continued to explore the world of meaning. His music demands that the listener "think." To interpret the meaning of the lyrics, understand the ideas behind them, and compare them with one's own life. Ozawa's intellect is a classic example of humanities intelligence—the intellect that deals with words and meaning.

On the other hand, Keigo Oyamada erased words and moved toward the design of environments.

In his activities as Cornelius, he reduced lyrics to the limit, eventually eliminating them almost completely. What he deals with is not meaning, but acoustics. Not the meaning carried by words, but the environment structured by sound. His music does not directly demand that the listener "think," but changes the conditions in which the listener is situated. As a result, the listener's thoughts and emotions shift. Oyamada's intellect is a classic example of environmental intelligence—the intellect that deals with conditions and structure.

This is not a conflict.

The directions of Ozawa and Oyamada do not contradict each other. Rather, each pursued to the limit two important aspects of human intelligence. Humanities intelligence digs deep into meaning and understands the world through words. Environmental intelligence designs conditions and changes the world through structure. Both are necessary. And by diverging, the possibilities of each were pursued in a purer form.

It was a divergence of two intellects: humanities intelligence and environmental intelligence.

Today, we tend to overemphasize humanities intelligence. Education is structured around words and logic, and evaluation is conducted based on "what one can say." Yet, it is not only words that shape the world. The environments we are placed in—physical, social, informational—strongly define our thoughts and actions. Environmental intelligence is the intellect that acts on this layer of the environment. It functions beyond words.

8. The Purification of Environmental Intelligence

Cornelius is an existence that purified environmental intelligence to the limit.

Tracing the transition of his works, a consistent direction comes into view. Sounds decrease, words disappear, and assertions vanish. His early solo works still included lyrics. Yet after "Fantasma," lyrics fragmented, eventually appearing only as phonetic sounds devoid of meaning. In "Point," the instrumental sounds themselves were stripped to the limit, letting the design of space and time take center stage. In recent works, dryness and stillness have increased further, pursuing acoustics that are almost environmental noise.

What remains is only the environment as condition.

In his music, there is no longer "something to convey." No mechanism to stir emotions, no intention to push a message. There is only the design of the auditory environment. How sounds are placed, how time flows, how quietness functions—only that matters. At this point, music becomes completely OS-like.

Music as an OS—let us delve deeper into this metaphor.

An operating system is not an end in itself. It provides the foundation for other programs to run. The user does not "use" the OS itself, but uses the applications running on it. Ideally, an OS is not conscious. The best OS does not make its presence felt.

Cornelius's music occupied a similar position. His music is both an "object of appreciation" and a "foundation" for the listener to experience something. After listening to his music, the way the world sounds changes. This is not because his music was "wonderful," but because his music temporarily rewrote the conditions of hearing. His music is appreciated, and simultaneously functions as an OS for other experiences to occur.

The purification of environmental intelligence is, in this way, the complete transition of music from "expression" to "condition." And when that transition is complete, music becomes something that can no longer be captured within the framework of music. It is the design of the perceptual environment, the OS of hearing.

Supplement: The Transition of Cornelius's Works

Let us trace the transition of Cornelius's works a bit more concretely. During the Flipper's Guitar era, Keigo Oyamada still centered lyrics and melody. However, in his 1993 solo debut album "The First Question Award," acoustic experimentation had already begun. "Fantasma" in 1997 is a monumental work where his direction became clear. Employing sampling and collage techniques, he carved out a new way of placing sounds spatially. In songs like "Star Fruits Surf Rider," countless fragments of sound are arranged three-dimensionally, giving the listener the sensation of being "inside" the sound.

In "Point" (2001), minimization advanced further. Sounds were fewer, space was broader, and quietness was used more boldly. In songs like "Drop," a single sound rings out for a long time, and the next sound appears only after waiting for its resonance to fade. With this album, Cornelius's music completely acquired its character as an "environment."

Recent works—the 2017 album "Mellow Waves" and subsequent sound installations—hold even more stillness. Acoustics close to environmental sound, elements stripped to the limit. His music is beginning to blur even the boundaries of the act of listening. Is it music, or is it environment? Cornelius has reached the point where that distinction holds no sway.

Part III: Technology, Ethics, and the OS

9. Technology and Disquiet

What is shared in the genealogy since YMO is the absence of simple celebration of technology.

Attitudes toward technology often split into two extremes. On one side is the unconditional praise of technology. Technological progress is good, and more technology brings a better world. On the other side is the hostility toward technology. Technology alienates humans, destroys nature, and robs us of freedom. Both attitudes simplify technology.

What is common to the genealogy since YMO—Ryuichi Sakamoto, Flipper's Guitar, Cornelius—is an attitude that aligns with neither. They use technology while always embedding a sense of disquiet within it.

Mechanical sounds symbolize the future while suggesting the absence of the human.

The synthesizer sounds in YMO's music were certainly futuristic. To listeners at the time, it felt like a window to an unknown world. Yet at the same time, those sounds lacked human warmth. Sounds generated by machines hold no trace of human hands. There, longing for technology and anxiety toward it coexisted.

Electronic repetition is a symbol of efficiency while letting us feel the loss of life's fluctuations.

The precise rhythms carved by sequencers can never be mimicked by a human drummer. That precision holds a certain beauty. Yet at the same time, the subtle fluctuations of human performance—fluctuations in tempo, variance in intensity—are lost. The traces of life fade, and only mechanical perfection remains. This sense of loss is the source of disquiet lurking in YMO's music.

This ambivalence is the starting point of environmental intelligence.

Environmental intelligence does not simply affirm or deny technology. Technology is an important element structuring our environment. Yet, the impact of technology on the environment is always ambivalent. Technology expands freedom while creating new constraints. Technology opens possibilities while closing them. Environmental intelligence is the intellect that recognizes this ambivalence and designs the conditions for living with technology.

10. Questions Born the Deeper One Understands Technology

The more deeply one is involved with technology, the more surely one arrives at a certain point.

Superficial users of technology treat it as a tool. Smartphones for communication, computers for work, cars for transportation. A tool is a means to an end. They do not think deeply about the means itself.

However, those deeply involved with technology—those who design it, those who understand its principles, those who study its impact on society—eventually face a certain question. It is the question that appears after the excitement of functionality fades.

"How does this technology change the human?"

Smartphones changed the distribution of our attention. Social media changed our self-perception. Algorithms changed the information we see. These changes may be intentional or unintentional. Yet, change is occurring certainly. And whether that change is good for humans—this question inevitably appears to those deeply involved with technology.

The moment this question is born, technology ceases to be a mere tool. It is recognized as a force that changes the conditions of society. And from here, the question of ethics inevitably rises.

Technological ethics is gaining more importance in recent years. Artificial intelligence, gene editing, surveillance technology—these are not mere tools, but hold the power to change the very conditions of human existence. The idea of "using" technology can no longer capture it. Technology defines what kind of world we live in. And thinking about that manner of defining is the new task of ethics.

11. The Transformation of Ryuichi Sakamoto

The one who symbolized this evolution most iconically was Ryuichi Sakamoto.

Starting as a member of YMO, Ryuichi Sakamoto, through his subsequent long career, continued to explore the relationship between technology, music, and society. His transformation shows a completed form in the genealogy of environmental intelligence.

Early on, he held a pure interest in the possibilities of technology.

Sakamoto during the YMO era was captivated by the possibilities of synthesizers and sequencers. New technology enables new sounds and new music. That excitement characterized his early works. Albums like "B-2 Unit" (1980) and "Left-Handed Dream" (1981) pursued the cutting edge of electronic music.

Yet, his interest gradually shifted. Environmental issues, war, human dignity, and stillness.

After the late 1980s, Sakamoto's activities began to transcend the framework of music. Interest in environmental issues, participation in anti-nuclear movements, and film scores starting with "The Last Emperor" (1987)—his interest shifted from the possibilities of technology to the state of the world where technology exists. In the 1990s, social involvement through music, such as works themed on environmental issues and performances in disaster areas after the Great East Japan Earthquake, increased.

In his late works, sounds became extremely scarce, approaching environmental sounds.

In "async" (2017) and late live performances, the brilliance of past electronic music faded. In its place was a single piano note, natural environmental sounds, long silence. His music, leaving only minimal elements, placed stillness itself at the center of the work.

This is not decline. It is the point where those who understand technology deeply eventually arrive.

Those who have fully pursued the possibilities of technology eventually arrive at a direction toward fewer things. Technology enables more things. Yet, the more things become possible, the sharper the question of what is truly necessary becomes. And when answering that question, the answer is often "less."

The trajectory of Ryuichi Sakamoto embodies this process. Starting from the cutting edge of technology, turning his eyes to the ethical issues of the world where technology exists, and finally reaching the minimization of sound, the pursuit of stillness. His late works are not decline, but maturity.

12. The OS as Environment

The OS is inconspicuous.

This fact has already been touched upon several times. The user recognizes applications but rarely directs attention to the OS itself. We are conscious of using Word or Chrome, but usually do not think about what Windows or macOS is doing behind them. Ideally, the OS is not conscious.

Yet, the OS defines the preconditions for all actions.

For an application to run, the OS must allocate memory, manage processes, and mediate input and output. Without the OS, the application cannot exist. Similarly, our actions are established upon countless "OS" structures. The physical environment, social institutions, informational infrastructure—these are all preconditions for what we do, what we think, and what we feel.

Environmental intelligence is the intellect that deals with exactly this layer.

Most intelligence operates at the level of the application. What kind of policy is good, what kind of product sells, what kind of education is effective—these are questions seeking optimal choices under existing conditions. But environmental intelligence questions the conditions themselves. Under what conditions is a good policy possible? In what kind of environment can people choose what they truly want? Through what kind of system does effective education naturally establish itself?

Cornelius's music quietly tunes the perceptual OS. And in society, a similar design is required. This is not about directly controlling action, but about preparing the conditions for action to establish itself naturally.

This distinction is decisively important in politics and institutional design.

Top-down approaches attempt to directly define people's actions. Prohibiting by law, mandating by regulation, guiding by incentive. These function to some extent. Yet, for people to "naturally" perform desirable actions, the design of the environment is required. An environment where people can live healthily, an environment where people want to learn, an environment where people can work creatively—when these conditions are prepared, control of individual actions instead becomes unnecessary.

The OS as environment is, in this way, the design of conditions that replaces direct control.

13. Ethics as Condition Design

Here, the meaning of ethics changes.

Conventional ethics has been understood as norms to judge right and wrong actions. One must not lie, one must not hurt others, one must keep promises—ethics is a system of such norms, and we should follow them. This understanding is correct in a sense. Yet, it captures only one side of ethics.

Ethics is not a norm that judges actions by right and wrong. It is the design of conditions to maintain a state where humans can judge freely.

From this perspective, the focus of ethics shifts from "right action" to "conditions under which right judgment is possible." For humans to judge right and wrong, certain conditions must be prepared. If fear is excessive, judgment is distorted. Under extreme fear, humans run to self-preservation, losing the composure to think of others. If anxiety is abundant, autonomy is lost. When anxiety about the future is too great, humans jump to short-term gains, losing a long-term perspective.

Ethics is the act of removing such noise and protecting the environment where humans can think quietly.

A good society is not one that forces people to perform "right" actions. It is a society where the conditions are prepared for people to think for themselves, judge for themselves, and take responsibility for themselves. For that, it is necessary to arrange an information environment that does not excessively fan fear and anxiety. We need institutions where excessive competition does not distort judgment. We need time and space for people to think calmly.

Ethics as condition design—this is the most important contribution of environmental intelligence to the domain of ethics. It converts ethics from individual behavioral norms to the design of conditions under which actions establish themselves. And that design is the very act of protecting stillness.

Supplement: Fear and Judgment

Psychological research clarifies the impact of fear on judgment. When fear is strong, the human brain enters "fight or flight" mode. At this time, long-term thinking, analysis of complex situations, and consideration from the standpoint of others are sidelined. Survival becomes top priority, and short-term safety becomes everything. In other words, in an environment of excessive fear, ethical judgment is difficult to establish in the first place.

Similarly, in an environment of strong anxiety, judgment is distorted. When anxiety about the future is great, people jump to immediate gains, losing a long-term perspective. When economic anxiety is strong, people prioritize self-preservation over consideration for others. Anxiety is the "noise" of judgment.

For ethical judgment to be possible, a certain peace of mind is necessary. When safety for oneself and loved ones is guaranteed to some extent, only then can humans think of others, hold a long-term perspective, and face complex ethical questions. Ethics as condition design is about preparing this "peace of mind." It is not about forcing correct judgment on people, but about making conditions where people can judge correctly.

Part IV: Solitude and Quiet Joy

14. Intellect Outside the Narrative

Human society is bound by shared narratives.

The nation is established by the narrative of citizenry. We share the same history and dream of the same future—at least, such narratives support the state. Success is given meaning by the narrative that effort is rewarded. Justice is understood by the narrative that good defeats evil. The meaning of romance and life are also shaped by the narratives we share.

By sharing the same narrative, people find peace, act, and connect. Narratives give us a place. We understand our lives as characters within a narrative. And we resonate and unite with others who believe in the same narrative.

Yet, environmental intelligence sees the world from outside the narrative.

One with environmental intelligence does not "believe" the narrative, but "observes" it. The narrative of the nation, the narrative of success, the narrative of justice—how they function, what structures they hold, what effects they produce. As long as one is inside the narrative, these questions are invisible. Because the narrative functions as a self-evident premise. But when standing outside the narrative, the narrative becomes an object of observation.

It does not believe the narrative, but observes its structure. Standing at this perspective, common premises are lost. Here, solitude is born.

To share a narrative is to share a view of the world. Those who believe in the same narrative naturally understand each other. But those standing outside the narrative fall outside that sharing. They do not take for granted premises that many take as natural. Their view of the world does not resonate with others. At this time, social solitude is born.

Yet, this solitude is not mere alienation. It is the inevitable consequence of a certain kind of intellect.

15. The Essence of Solitude

Solitude is not simply the state of being alone.

Being physically alone and being lonely are different matters. One can feel solitude even in a crowd. Conversely, being alone does not necessarily mean loneliness. The essence of solitude is not physical isolation, but lies in the dimension of meaning.

It is the state of being unable to share the premises of the world.

For us to resonate with others, a certain level of common premises is necessary. The sky is blue, effort is rewarded, justice exists—when sharing these premises, we can understand others. But those with environmental intelligence recognize the world as structure. They understand how narratives function. Therefore, they naturally relativize the narratives that many rely upon. To them, narrative is not "truth" but "structure." This difference in perception makes resonance with others difficult.

At this time, social resonance decreases. Yet simultaneously, another state appears.

As the price of solitude, a certain freedom is gained. Freedom unbound by narrative. Freedom liberated from the need to meet others' expectations. Freedom to live by one's own standards of judgment. And as external resonance decreases, the internal voice can be heard more clearly. Solitude is a loss, and simultaneously a condition for a certain kind of deepening.

16. Joy as Internal Tuning

When moving away from external evaluation and competition, the quality of joy changes.

Much of our joy depends on the external. Joy recognized by others, joy winning in competition, joy achieving goals—these are all defined by external standards. Without others, the joy of recognition is not born. Without competition, the joy of winning does not exist. Such joys are certainly powerful. Yet, they always carry instability. Others' evaluations can change. Competition always has losers. Even if a goal is achieved, the next goal appears.

It becomes not an exciting elation, but a sensation of quiet tuning.

Joy that does not depend on the external has a different quality. It is not exciting elation, but a sensation of quiet tuning. The noise between the world and oneself decreases, and action and consciousness naturally align. What one is doing and what one wants to do align. In this state, scarcity does not exist. No need to obtain anything. Comparison also becomes unnecessary. The question of how one compares to others ceases to make sense. What remains is a calm, enduring satisfaction.

The joy given by Cornelius's music is of this kind. Few would get excited listening to his music. Yet, many feel a quiet satisfaction. His music does not provide external stimulation, but tunes the listener's interior. After listening, the way the world sounds has shifted slightly. The relationship between oneself and the world is minutely adjusted. That is joy as internal tuning.

17. The Simultaneity of Solitude and Joy

Solitude and quiet joy are two sides of the same structure.

The less one depends on the external, the fewer the resonances. Shared meaning with others decreases, and social solidarity thins. In this sense, solitude deepens. Yet simultaneously, internal stability increases. One ceases to be swayed by external evaluations and can judge by one's own criteria. Noise decreases, and the essential voice can be heard.

This state is psychologically called integration.

"Individuation" in Jungian psychology, Maslow's "self-actualization," or "liberation" in Buddhism—various traditions have expressed this state in different words. What is common is a state liberated from external criteria where internal integration is achieved. It is not the destination of growth, but the beginning of harmony.

Those who trace the genealogy of environmental intelligence—those who touch Cornelius's music deeply, those who practice the philosophy of minimization—experience this simultaneity of solitude and joy. Social resonance might decrease. Yet, resonance with oneself deepens. And that deepening becomes the source of quiet joy.

Supplement: Two Types of Resonance

Human resonance holds two types. One is resonance with others. Believing the same narrative, sharing the same values, dividing the same emotions. This resonance is the foundation of social solidarity. By resonating with others, we are liberated from solitude and realize we are part of something larger.

The other is resonance with oneself. One's actions and consciousness align. What one is doing and what one wants to do align. Living not by external criteria, but according to the internal voice. This resonance deepens solitude. Because shared meaning with others decreases. Yet simultaneously, this resonance is the source of quiet joy. When in harmony with oneself, external evaluation is not important. Scarcity vanishes, and calm satisfaction appears.

Those who trace the genealogy of environmental intelligence often transition from the first resonance to the second. By standing outside the narrative, resonance with others decreases. Yet, resonance with oneself deepens. And this transition is not a loss, but a maturity of sorts. Both resonances are necessary. Yet, today we lean too much toward the first. Social media maximizes resonance with others, but it is often superficial. Recovering the second resonance—quiet harmony with oneself—is a direction shown by environmental intelligence.

Part V: The Philosophy of Minimization

18. What is Minimization?

Tracing the genealogy of environmental intelligence, a common tendency clearly appears. It is "minimization."

From YMO to Cornelius, and to Sakamoto's late works, a vector consistently pointing in the same direction is visible. Sounds decrease, words decrease, assertions decrease, and desires decrease. Even early YMO had fewer sounds compared to pop of the era. Mechanical repetition eliminated human ornamentation. With Cornelius, sounds were stripped to the limit, with silence occupying the majority of the work. Sakamoto's late works also point in a similar direction.

This phenomenon is often misunderstood. It is sometimes seen as decline or exhaustion. Creative power ran out, energy was lost, simply aging—such interpretations are made. Yet, they are incorrect.

It is not as decline or exhaustion. Rather, it is the opposite. Minimization is a state where only the essence remains. It is the result of seeing what is unnecessary.

Minimization is not a state of lacking. It is the process where, as a result of understanding what is truly necessary, unnecessary things naturally disappear. Young creators try to pack in many elements. They try all possibilities, all expressions. But mature creators are different. They can distinguish what is essence and what is addition. And they strip away the additions. What remains is only the essence.

The transition of Cornelius's music embodies this process. Early works still included many elements. Yet as time passed, elements decreased. And the more they decreased, the more the importance of what remained grew. A single sound carried what previously was expressed with ten sounds. Silence played the role previously played by melody. Minimization is, in this way, the technique of expressing more with fewer elements.

19. The True Nature of Complexity

The Era of Information Overload

The era we live in is called the era of "information overload." The internet made access to all information possible. Yet, the amount of accessible information far exceeds the amount humans can process. The amount of data generated daily is increasing exponentially. Within the flood of information, we are pressed to judge what is important and what is not. And that judgment itself is made difficult by excessive information.

In this situation, understanding the essence of complexity becomes increasingly important. Complexity is not a question of the amount of information. It is a question of the distinction between essence and noise.

The world looks complex.

Around us, countless pieces of information overflow. News, social media, ads, human relationships, work tasks—the information to process always exceeds our capacity. The world is complex, and that complexity seems to continue to grow.

But mature intellect eventually notices. What makes the world complex is not the abundance of essence, but the abundance of noise.

Complexity has two types. Essential complexity—the amount of information truly necessary to understand a phenomenon. And additive complexity—the state where information unrelated to the essence hinders understanding. In many cases when we feel "it is complex," what is actually occurring is the latter. Noise is too great, making the signal invisible. Information is too much, hiding the essence.

Early understanding proceeds by increasing information. When trying to understand something, we first gather information. Learn more, research more, experience more. At this stage, the increase of information is bound to the deepening of understanding.

Yet final understanding is reached by decreasing information. After gathering sufficient information, ask what is truly necessary. And strip away the unnecessary. What remains—that is the essence of the phenomenon. Only in stillness does structure become clear.

This recognition applies to all fields. In science, a good theory explains many phenomena from a few principles. In design, a good product fulfills its function with the minimum necessary elements. In life, the things that are truly important can be counted on one hand. The true nature of complexity is not the abundance of essence, but the abundance of noise.

20. Principles of Environmental Design

In the intellect that deals with environments, a universal principle exists. The quality of an environment is not improved by addition. It is improved by subtraction.

This principle seems counterintuitive. Adding more things makes the environment better—it is natural to think so. Adding things to a room makes life rich. Adding elements to music makes expression rich. Adding regulations to institutions makes society better. Yet, the opposite is often true.

A good space has few things. In a space with no excess, necessary things stand out, movement becomes smooth, and the mind calms. This is why the cells of Zen temples and minimalist residences feel pleasant.

A good acoustic has little noise. In the design of concert halls, the most important is the control of reverberation. Reducing unnecessary reflections, letting only the necessary sound be heard. Stillness makes sound stand out.

A good system has few unnecessary constraints. To let people's creativity be exercised, excessive rules are counterproductive. Setting only the minimum necessary rules, leaving the rest to people's judgment. Minimization is the act of maximizing the quality of the environment.

This principle is common to Cornelius's music, traditional Japanese aesthetics, and good technical design. Subtraction, not addition. Few, not many. This is the fundamental principle of the intellect that designs environments.

21. The Recovery of Freedom

When information decreases, human freedom is recovered.

This proposition seems counterintuitive. Information expands freedom—we tend to think so. If there is more information, we can make better choices. If there are more options, we are freer. Yet, the opposite is often true.

Excessive stimulation distorts judgment. When information is too much, we cannot distinguish the essential from the additive. Everything looks important, and we cannot prioritize. As a result, judgment paralyzes, depending on others' opinions or algorithmic recommendations.

Excessive options weaken autonomy. When options are too many, choosing itself becomes a burden. And after choosing, regret of "was there something better" is born. Freedom of choice instead brings constraint.

Excessive institutions constrain action. When rules are too many, people spend energy following rules, losing sight of the original purpose. Form takes priority over substance, and creativity shrinks.

Minimization does not directly control human action, but creates the margin where action naturally establishes itself. It is not limitation, but a condition of freedom.

By minimization, noise is removed. Then, what is truly important becomes visible. When options decrease, the weight of each choice increases. When institutions are simplified, people can focus on the essence. Minimization does not limit freedom, but prepares the conditions under which freedom can be exercised.

22. Minimization as Culture

This philosophy has long existed at the center of Japanese culture.

While Western aesthetics often emphasized "addition" and "ornamentation," traditional Japanese aesthetics emphasized "stripping away" and "margins." This contrast might be a bit simplified. Yet, it is certain that the aesthetics of minimization stand out in Japanese culture.

Zen gardens are structured by blanks. In a garden of only stones and sand, the stones represent islands and the sand the sea. Water is not actually there. Yet, through the viewer's imagination, the sea appears. Blankness creates meaning.

Haiku strips away words. The extreme form of seventeen syllables does not allow excess words. Only selected words remain, and in the margin between them, the reader's imagination enters. "The old pond / a frog jumps in / sound of water"—this seventeen-syllable poem leaves infinite resonance.

The tea room is simple to the limit. Gorgeous decoration is excluded, and only natural materials are used. In a narrow space, only the minimum necessary things are placed. That simplicity instead brings a rich experience.

Calligraphy is completed by margins. The inked portion and the uninked portion unite to structure the work. The margin is not mere blank. It is the space for the written portion to breathe.

These are all aesthetics of minimization. There, silence holds more value than description, harmony more than assertion.

That Cornelius's music evokes a special resonance in Japanese listeners might be because of this cultural soil. Stillness, margins, minimization in his music—these deeply connect with traditional Japanese aesthetics. His music is accepted particularly naturally within the Japanese cultural context.

23. Technology and Minimization

The deeper one is involved with technology, the clearer the importance of minimization becomes.

The biggest problem of technology is excess. Technology always holds a tendency to enable "more." More functions, more information, more connections. And if that tendency is not controlled, it proceeds boundlessly. Functions multiply, information floods, and complexity expands exponentially.

Smartphone apps were simple at release. Yet as time passed, functions were added, the UI became complex, and users were overwhelmed. Software is the same. Functions increase with each version, and eventually no one can understand the whole. Technological evolution is often synonymous with complexification.

Mature technology designers do not increase functions. They ask what is truly necessary. And they hold the courage to cut unnecessary functions. They simplify structures and aim for invisibility. The best technology hides complexity. To the user, only a simple interface is visible. The complexity behind it is appropriately abstracted and hidden.

The best OS does not make its presence felt. It functions as stillness.

The best technology we use—it is the technology that does not make us conscious of using it. A door handle, if designed correctly, is not conscious in use. Good software is the same. It enables what the user wants to do, and the process itself remains outside consciousness. Technology functions best when it functions as stillness.

Supplementary Chapter: Philosophy of Listening

I would like to re-examine the philosophy of environmental intelligence discussed in this book from another angle. It is about the act of "listening" itself.

The Activeness of Listening

When we "listen" to music, we typically feel we are passive existences. Sound flows in, and we receive it. But truly excellent listeners are active. While letting themselves flow with the sound, they are simultaneously conscious of how they are listening. Which sound to direct attention to, which sound to recede to the background. Which moment to capture, which moment to let go. Listening is a sequence of choices.

Cornelius's music demands this active listening. His work does not allow passive consumption. Because sounds are few, the listener's participation is indispensable. The listener waits for the next sound in the stillness, structuring the relationship between sounds themselves. This activeness deepens the experience of his music.

Listening and Existing

When listening to music, we go back and forth between two modes. One is listening to music as an "object." Music is outside us, and we observe it. The other is becoming "one" with the music. The boundary between music and oneself grows ambiguous, and we are inside the music.

Cornelius's music induces the second mode. In his work, music does not stand as an "object" but envelops us as an "environment." We are not listening to music, but existing along with it. This shift in the mode of existence is the core experience of his music.

The Ethics of Listening

Listening holds an ethical aspect. When listening to others' words, we direct attention to them, striving to understand. Truly listening is temporarily suspending one's own judgment and opening to the other's voice. This attitude is also required when listening to Cornelius's music. His music does not meet our existing expectations. We must let go of expectation of what we should hear, receiving what the music presents as it is. The ethics of listening is this open attitude.

Supplementary Chapter: Practice of Environmental Intelligence

How can the ideas discussed in this book be practiced in daily life? I would like to present several directions.

Design of Information Environment

We are drowning in a sea of information. News, social media, ads—constantly flowing information scatters our attention and dulls judgment. The practice of environmental intelligence is, first, to design this information environment. What to see, what not to see. When to connect, when to disconnect. Intentionally choosing the information conditions one is placed in. It is not about rejecting information. It is about setting the "conditions" under which information flows.

Minimization of Physical Environment

Around us, there are many things. Are many of them truly necessary? The principle of environmental design—quality improves by subtraction—can also be applied to physical space. Reducing unnecessary things, leaving only what is necessary. In that process, what is truly necessary becomes clear. Minimization is not mere tidying. It is the practice of questioning the relationship between oneself and things.

Protecting the "Ma" of Time

In modern times, we have lost the "ma" of time. Gap times are filled with smartphones, and waiting times with information consumption. Yet, time doing nothing—blank time with no input—is indispensable for thought and creativity. The practice of environmental intelligence is to consciously protect this "ma." Setting time during the day to do nothing and consume nothing. Within that blank, what is truly important rises.

Practice of Listening

Listening to Cornelius's music as a practice of environmental intelligence. It is not playing it as background music. Setting time dedicated to listening, directing attention to both sound and stillness. After listening, observing how the way the world sounds changed. This practice experientially teaches that the conditions of perception are variable.

Environmental Intelligence and Design Thinking

The philosophy of environmental intelligence is deeply bound to the domain of design. In recent years, "design thinking" has gained broad attention. It is a methodology centering the user's experience as an approach to problem-solving, repeating prototypes, and stacking improvements. Yet, from the perspective of environmental intelligence, design thinking requires an important complement.

Design thinking often focuses on "what to add." New functions that meet user needs, new elements that improve experience. But environmental intelligence teaches that, in many cases, "what to delete" is more important. Excellent design strips away unnecessary elements, leaving only the essence. Apple products are valued not because functions were added, but because functions were stripped, simplifying the interface. The practice of environmental intelligence is to hold this perspective of "stripping away" in design as well.

Concluding Chapter: Civilization as Stillness

24. Mature Stages of Civilization

In the early stages of civilization, expansion is value.

More resources, more information, more functions. For civilization to grow, expansion is first necessary. Broadening territory, increasing population, expanding production. At this stage, "more" is good. Expansion is the condition of survival and prosperity.

But at the mature stage, values shift. Not increasing, but maintaining becomes the center.

After civilization reaches a certain scale, simple expansion becomes unsustainable. Resources are limited. The environment has a capacity. And the point comes when the cost of expansion exceeds its benefits. Mature civilization emphasizes maintenance and adjustment over expansion. How to maintain what already exists in a sustainable way. This is the central task of the mature stage.

What becomes important here is stillness. Stillness is not stopping. It is a state where all elements are in harmony.

Stillness is not a state where nothing happens. It is a state where there is no excessive movement, each element is appropriately placed, and the whole is in harmony. When an orchestra maintains stillness, it is not stopping the performance. Each player understands their role, emitting no excess sound, contributing to the harmony of the whole. The stillness of civilization is the same. It is not that activity stops, but that activity is conducted in a harmonious form.

25. Civilization as Condition

What supports civilization is not visible institutions or technology.

We often understand civilization by its representations. Laws, political institutions, technology, art—these are certainly part of civilization. Yet, these are "results" of civilization, not "causes." What truly supports civilization lies in a deeper layer.

It is the condition under which humans can freely think, judge, and act.

For good laws to function, the conditions must be prepared for people to respect laws. For good technology to be used, the conditions must be prepared for people to use that technology appropriately. And these conditions are not guaranteed by laws or technology itself. They are supported by education, trust, room, stillness—countless factors difficult to see.

This condition is maintained not by force, but by quiet design. It does not assert itself. Yet the moment it is lacking, civilization collapses.

History has repeatedly shown this fact. Prosperous civilizations suddenly collapse. At that time, the direct cause might be war or disaster. But the deeper cause is that the conditions supporting civilization—trust, room, stillness—had been damaged before anyone noticed. Conditions are inconspicuous. But when they are lacking, everything collapses.

Let us consider the collapse of the Roman Empire as an example. Direct causes are listed variously, such as barbarian invasions, economic chaos, political corruption. But more fundamentally, the conditions supporting Rome—citizens' community spirit, trust in law, room to hold a long-term perspective—were gradually damaged with the expansion of the empire. The process of damaging conditions is inconspicuous. Daily life continues, and institutions are maintained in form. But before anyone notices, people stop believing in law, lose a sense of belonging to the community, and pursue only short-term gains. And when crossing a certain critical point, civilization collapses.

Our contemporary civilization faces a similar danger. Technological progress is remarkable. But are the conditions—where people can think calmly, hold a long-term perspective, and trust others—truly maintained? Excessive information is robbing us of stillness. Economic anxiety is robbing us of room. Division is damaging trust. The conditions supporting civilization might be damaged in an inconspicuous form.

26. The Role of Stillness

Stillness exists in the background of civilization. It holds no voice.

When we talk about civilization, what is talked about is typically conspicuous things. Great leaders, epoch-making inventions, dramatic events. But what makes civilization possible is not those conspicuous things. It is that daily life is led calmly, people can think quietly, and perform creative work—such stillness.

Yet all voices are established upon stillness.

In music, sound is established upon stillness. In complete noise, music cannot exist. Because there is stillness, sound holds meaning. Similarly, all activities in civilization—economic activities, artistic activities, political activities—are established upon stillness. For people to think calmly, discuss, and create, a certain stillness is necessary. When that stillness is lost, activities fall into chaos.

Environmental intelligence is the intellect that protects this stillness. It does not aim to change the world. It quietly continues to prepare the conditions where the world does not break.

Environmental intelligence does not seek heroic transformation. It quietly maintains inconspicuous but important conditions. It does not assert loudly, but functions in the background. And that modest function makes civilization sustainable.

27. Conclusion

The genealogy of environmental intelligence consistently points in the same direction.

YMO showed disquiet toward the relationship between technology and humans. While using technology, they etched the coldness of technology and the thinning of the human into music. They rejected simple praise of technology, expressing ambivalence.

Flipper's expressed the instability of meaning. The world is a gathering of fragments, and grand narratives do not hold. Through citation and collage, they made this sensation into sound.

Cornelius redesigned the conditions of perception. He converted music from expression to environment, from stimulation of emotion to design of conditions. His music quietly tunes the auditory OS.

And on that extension, the task of designing social conditions appears. The philosophy of environmental design in music can be expanded to the philosophy of condition design in society. Ethics is not a norm of action, but the design of conditions under which action establishes itself. Civilization is not visible institutions, but the conditions under which people can freely think and judge.

The destination of this flow is not expansion. It is minimization.

What the genealogy of environmental intelligence consistently points to is "less," not "more." Reducing sounds, reducing words, reducing assertions, reducing desires. And through that stripping away, the essence appears.

Minimization is not about losing something. It is the process of quietly removing the noise between the world and oneself.

We live surrounded by noise. Excessive information, excessive stimulation, excessive desires. They hinder us from seeing what is truly important. Minimization is quietly removing this noise, one by one. It is not about losing something. It is about becoming able to see what is truly necessary.

What appears beyond that is not empty blank. It is civilization as stillness.

Civilization as stillness—it is not a civilization without noise. It is a civilization where all elements are in harmony, unnecessary noise is removed, and the conditions are prepared for people to exercise their inherent abilities. It is not a civilization competing in expansion, but a civilization maintained in a sustainable form. It is not a civilization asserting loudly, but a civilization functioning quietly.

Cornelius's music gives a certain premonition of such a civilization. Listening to his music, the world looks slightly different. Noise decreases, and essence stands out. And beyond that, the figure of civilization as stillness is faintly visible.

---

Afterword

This book began with an encounter with the music of Cornelius. One day, I happened to listen to his work, and was struck by a sensation I had never experienced. I was supposed to be listening to music, yet I was inside the music. I was supposed to be consuming sound, yet I existed along with the sound. That experience became the starting point of a long contemplation.

Putting that contemplation into words was not easy. The essence of Cornelius's music lies beyond words. Translating what he expresses through sound into words is, in a sense, impossible. Yet, the ideas inspired by that music—environmental intelligence, stillness, minimization—can be communicated to some extent through words. This book is a record of that attempt.

Tracing the genealogy from YMO to Flipper's Guitar, Cornelius, and Ryuichi Sakamoto, a grand flow came into view. It is a flow that transitions music from human expression to environmental design. And that flow transcends the domain of music, reaching technology, ethics, and the state of civilization. Environmental intelligence is a concept that should be understood within this broad context.

I hope this book serves as an opportunity for contemplation for the reader. Listening to Cornelius's music, thinking about the meaning of stillness, practicing the philosophy of minimization—I hope that in that process, the reader's own environmental intelligence grows.

Finally, I would like to offer gratitude to all the artists who opened this genealogy of music and thought—Yukihiro Takahashi, Haruomi Hosono, Ryuichi Sakamoto, Kenji Ozawa, Keigo Oyamada, and the countless predecessors who exerted influence. Without their works, this book would not exist.

Conceptual Context

The philosophy of environmental intelligence resonates with conceptual traditions such as: the concept of "Lebenswelt" (lifeworld) in phenomenology, the concept of "affordance" in ecological psychology, and the philosophy of "ma" and "margins" in Japanese aesthetics. These provide perspectives to understand humans in relationship with the environment.

Supplement: Phenomenology of Acoustic Space

I would like to organize the concept at the core of this book—capturing music as "environment"—using terms from phenomenology.

Intentionality of Sound

In Husserl's phenomenology, consciousness is always consciousness "of something." Consciousness is intentional, pointing toward an object. When listening to music, our consciousness points toward sound. But in normal music appreciation, the focus of our consciousness is on the object called "music." Music is an object that stands before us.

When listening to Cornelius's music, this structure of intentionality changes. The focus of consciousness shifts from the object of "music" to the situation of "being inside the music." Music is not an object, but an environment that envelops us. The structure of Heidegger's "being-in-the-world"—we are always already within the world—is clearly experienced at the level of hearing. We do not place music before us as an "object," but are within the "world" along with music.

Body and Environment

Merleau-Ponty's body theory showed that our perception is bound to the world through the body. We do not understand the world "with the head," but participate in the world "with the body." Listening is also a bodily act. The ear, as part of the body, is open to the acoustic environment.

Cornelius's music manifests this bodily participation. Listening to his music, we feel we are a body "existing" in acoustic space. Sound arrives from left and right, front and back, enveloping us. Our body is positioned as part of the acoustic environment. This experience shakes the Cartesian self-understanding of "observing subject." We are not observing the world from outside, but exist within the world as a body. Cornelius's music lets us experience this mode of existence through hearing.

Phenomenology of Time

Music is essentially a temporal art. Sound unfolds in time, and the listening experience is inseparable from the flow of time. But time in Cornelius's music holds different properties from typical music.

In typical music, time flows relatively homogeneously. The tempo is constant, the meter is regular, and the listener can predict the flow of time. But in Cornelius's work, time stretches and contracts. In some parts, time is stretched, and a single sound rings out long. In another, multiple time layers overlap. The listener becomes unable to predict the flow of time. That uncertainty prompts the active participation of the listener. When the next sound will come, how long the silence will last—the listener sharpens attention and waits. This waiting experience manifests the phenomenological structure of time. Time is not an objective thing flowing uniformly outside us. Time is the very structure of our experience. Cornelius's music explores this experiential nature of time through sound.

Supplement: Soundscape and Environmental Intelligence

Acoustic Ecology Perspective

Canadian composer R. Murray Schafer proposed the concept of "soundscape" in the 1970s. Soundscape refers to the entire environment of sound surrounding us, likened to a landscape. Just as we live within a visual landscape, we live within an acoustic landscape—a soundscape. Schafer pointed out that modern urban environments are filled with "lo-fi" sounds—mechanical sounds, traffic noise, artificial din—and appealed for the importance of the quality of the acoustic environment.

The philosophy of environmental intelligence is deeply bound to this concept of soundscape. Cornelius's music can be said to design a kind of "ideal soundscape." His work structures the acoustic environment enveloping the listener. That environment is not filled with excessive sound, and stillness and sound are appropriately placed. The experience of listening to his music is the experience of placing oneself in an acoustically healthy environment.

Hierarchy of Sound

In conventional music, sound holds a clear hierarchy. Melody in the foreground, accompaniment in the background. The protagonist and supporting roles are clearly distinguished. But in music as environment, this hierarchy becomes ambiguous. In Cornelius's work, all sounds hold almost equal weight. There is no structure where one sound is "master" and other sounds are "servant." Sounds, as components of the environment, each occupy a unique position. This equality removes the listener from the "center," positioning them as "part" of the environment.

Democratization of Hearing

Music of environmental intelligence, in a sense, realizes the "democratization of hearing." In conventional music, the listener is expected to listen according to the focus set by the composer or performer. Directing attention to melody, raising emotion at the chorus, experiencing catharsis at the drop. The distribution of the listener's attention is "designed" to some extent.

But in Cornelius's music, broad freedom is given to the listener. Which sound to direct attention to, which moment to feel important—the listener decides. Because sounds are few, the listener's choice holds meaning. In this sense, his music realizes the democratization of hearing—where the listener can choose their own way of listening. And this democratization aligns with the principle of environmental intelligence "preparing the conditions under which action naturally establishes itself." He does not force a specific way of listening on the listener. He merely designs the conditions under which the listener can listen freely.

Supplement: Stillness and Creativity

Creative Function of Blankness

Research on creativity often points to the importance of "incubation." After working intensively on a problem, leaving time to do nothing for a while can suddenly bring solutions to mind. This time "doing nothing"—time apart from conscious thought—enables creative insight. The brain performs unconscious processing while conscious thought is resting. Stillness, blankness, "ma"—these are indispensable conditions for creativity.

The stillness of Cornelius's music provides this creative blank. Listening to his work, the listener is not exposed to constant stimulation. Within the rhythm of sound and stillness, consciousness repeats tension and relaxation. In that moment of relaxation—when nothing is heard, or only minimal sound is heard—room is born for new thoughts and sensations to rise. His music is like an auditory meditation. And as research shows meditation increases creativity, his music also holds the possibility of promoting the listener's creative thought.

Attention Restoration Theory

Environmental psychologists Rachel Kaplan and Stephen Kaplan proposed "Attention Restoration Theory." According to them, our directed attention (attention intentionally directed to something) fatigues with continued use. But when placing ourselves in natural environments or stimuli that are not too complex and not too simple, our attention is "restored." Seeing natural landscapes, listening to quiet music—these experiences heal attention fatigue, restoring cognitive resources.

Cornelius's music holds properties that promote this attention restoration. His work does not strongly capture the listener's attention. There is no excessive stimulation. The listener can freely choose to direct attention or not. This "freedom of choice" enables attention restoration. This might be why many feel their heads cleared after listening to his music. Music of environmental intelligence provides a place for attention restoration through hearing.

Supplement: Genealogy of Minimalism

The philosophy of "minimization" in environmental intelligence resonates with the genealogy of minimalism in 20th-century art. Minimal Art, which rose in the US in the 1960s, stripped expression elements to the limit, leaving only the essence of form, color, and material. The important insight of Minimal Art is that what is important is not "what the work expresses" but "what kind of experience it generates." The work is an object standing before the viewer, and simultaneously the "place" the viewer experiences. This transition—from expression to experience—runs parallel to the transition made by Cornelius's music.

In the domain of music, Steve Reich, Philip Glass, and others pioneered Minimal Music. Repetition, gradually changing patterns, long duration—these characteristics change the listener's sense of time. Cornelius can be said to inherit this minimal music tradition within the context of pop music. Stillness, margins, minimization in his music—these deeply connect with traditional Japanese aesthetics. He fused Western electronic music and Japanese aesthetic sense in a unique form.

Supplement: Environmental Intelligence and Education

The philosophy of environmental intelligence provides important suggestions to the domain of education as well. Conventional education focused on "what to teach." But from the perspective of environmental intelligence, equally important is "under what conditions to learn." For students to truly learn, the conditions must be prepared: an environment where they can fail with peace of mind, sufficient time, space without excessive stimulation, room to think quietly.

Environmental intelligence in education is not about "making" students do something, but about preparing the conditions where students can learn naturally. Modern classrooms are often filled with excessive stimulation. But what is truly necessary for learning is often "empty" time. A quiet classroom is not a classroom where nothing happens. It is a harmonious environment for students to think at their own pace, and for learning to be born from within.

Supplement: How to Read This Book

This book can be read all at once, or in parts. Each chapter is independent to some extent, and you can start reading from the chapter of interest. However, to understand the whole flow, I recommend reading in order from the introduction. The concept of environmental intelligence is introduced in Part I, its genealogy traced in Part II, and expanded to technology, ethics, and civilization in Part III and after. By following this flow, the deepening of the concept is easier to understand.

The supplements and addenda supplement the main argument. Reading them after or alongside the main argument deepens understanding. The related work list in the appendix serves as reference when reading while actually listening to music. Cornelius's music holds something that cannot be communicated through words. To truly understand the philosophy of this book, the experience of listening to his works is indispensable. I highly recommend readers read this book while listening, or after listening.
