1. ASPECTS OF THE SINE-CURVE

The concept of sine curves, i.e. regular upswings and downswings, can be used as a metaphor and, at the same time as a guideline in many areas of life. It describes cyclical movements, phases of peaks and troughs. Sine-curves in politics, sport, science, health, recreation and psychology, faith and religion - what are they alll about?

This consideration of the sine-curve as a model for cyclical processes could be of interest to many different groups, depending on the context and perspective. Therapists and coaches use cyclical models to show people in crisis that setbacks are part of growth processes. People in phases of personal upheaval find comfort in the idea that low points can precede turning points. Psychiatrists and neuroscientists recognize that mental states, for example in bipolar disorder or hormonal fluctuations, often have wave-like patterns.

Economists and investors think in cycles anyway. In economic cycles, market cycles and recessions, the sine-curve describes the classic patterns of upswings and downturns. Entrepreneurs recognize that success and failure often occur in waves and that anti-cyclical thinking can make strategic sense. Change managers in companies understand that change is not linear. It occurs in waves with resistance, integration and new balances as predictable, cyclical patterns that can be actively controlled with strategic intelligence. Systems thinkers view societies, organizations or entire civilizations as complex, self-regulating systems with ups and downs.

This can be observed particularly well in politics. Democracies are constantly experiencing wave movements from upsurge to crisis of confidence, from reform to protest, from stability to shock - and back again. At present we see in many places the low point of such cycles as loss of confidence, polarization, doubts about the system. But the next ascent often starts from the valley.

In the economy, the sine curve has long been a standard model: economy, recession, recovery, boom - everything returns. For investors, the downturn is not the end of the world, but part of the dynamic. Countercyclical thinking is sometimes the key to long-term success. The model also plays a role in psychology. Emotional states, especially with affective disorders, often run wavy. Coaches and therapists use the idea of the sine curve to show clients: it is normal that it goes up again down - and vice versa. Low points are not end stations, but often turning points.

In companies, change managers do not understand change as linear progress, but as movement in waves. There is resistance, chaos, reorganization before a new balance is established. Those who try to skip this process will rarely achieve sustainable results. And even in faith and religion, often far from mathematical models, the thought is found again between doubt and hope, withdrawal and devotion, crisis and renewal. Spiritual cycles remind us that growth rarely takes place in the permanent high, but precisely in the depth it gains its impulses.

In mathematics, the values regularly fluctuate between a maximum of +1 and a minimum of -1, the so-called amplitude. It is point-symmetrical to the origin, which means that every upswing has a corresponding downswing. In life, the phases of high points and challenges or low points also alternate.

The sine-curve is a powerful model for describing cyclical, wave-like processes, whether in biography, in systems or in the mind. The relevant data depends on the frame of reference; it can be quantifiable, such as hormones or market indicators, or qualitative, such as crises or insights. Change is not an exception, but the rule. They remind us that lows are not the end, they are the part of a natural process. Everything happens in cycles, sometimes up and sometimes down - this is quite normal. What exactly changes depends on what you are looking at. These can be measurable things, such as hormone levels or stock market prices. But it can also be about personal experiences, such as crises, moments of revelation or emotional highs and lows. Just as the sine-curve oscillates between peaks and troughs, human experiences, emotions, economic cycles, and even historical events often follow similar rhythms. Recognizing this pattern can be grounding. Highs are exhilarating, but not lasting. Lows are challenging, but also temporary and often productive.

Movements are part of a cycle and rarely follow a straight line. These processes, whether in personal growth, in the economy, in relationships or in nature, are not linear, they are undulating. A difficult phase is often followed by a better time, just as every low point on the sine-curve is followed by a high point. The sine-curve makes it clear that ups and downs are part of life and occur in a certain rhythm. This can help us to accept difficult phases as temporary and to know that better times will come again. Those who perceive the intensities in the fluctuation range of the sine-curve are practising a new form of mindfulness. It is a listening for nuances, an inner sense of the quality of the present, not just its form.

A few bad years, economically, socially and politically - and the collapse is here. What was considered stable yesterday, with no alternative, can already topple today. Democracies are not natural states either. They are constructs and therefore just as destructible as they are protectable. It often doesn't take much. All it takes is a few bad years and decades of established certainties crumble. Trust in institutions? International order? Liberal achievements? Crises are no longer an exception, they are the norm. And that is precisely what makes our systems so vulnerable. This sobering but accurate analysis touches a nerve of the present and the question “Who cares?” is not just rhetorical, it is above all very topical.

For human history, societies have leaned heavily on the idea of stability. Empires, currencies, political systems, corporations, and technologies all once appeared immovable, pillars around which daily life revolved. But time has a way of unraveling even the most deeply held assumptions. What was considered stable yesterday, with no alternative, can already topple today. The sine-wave begins to reveal itself.

Empires like Rome, Byzantium, or the Soviet Union once seemed unshakable. Yet all of them fell, not necessarily because of external enemies, but often due to internal stagnation, overconfidence, and a failure to adapt. The same is true of corporations like Kodak or Nokia, which once stood as symbols of innovation, only to fall because they believed themselves irreplaceable.

In today’s world, shaped by digital disruption, climate change, shifting geopolitical forces, and social fragmentation, the sinewave runs faster. The half-life of trends, technologies, and political assumptions is shrinking. What seems without alternative today can be irrelevant by next week. So what does this mean for us, as societies, as individuals? Above all, it means learning to live with instability without succumbing to fear or cynicism. Those who recognize the sine-wave, also recognize its opportunities. Every collapse creates room for reinvention. Instead of clinging to illusions of permanence, we must cultivate flexibility in thought, in systems, in action. Stability is not a permanent condition, but a snapshot in motion. To believe otherwise is to be blind to change. But those who understand that even the firmest ground can shift are the ones most prepared, not just to survive the wave, but to shape what comes next.

Civilization is thin. The varnish of modernist stability is cracking faster than many believe. A few years of inflation, identity conflicts and constant media noise and order loses its cultural self-evidence. The collapse is then not so spectacular, but rather gradual. And that is precisely what makes it so dangerous. This dialectic determines how states and international players react to crises, adapt to new challenges and help shape the global order. In a world marked by multiple centers of power, escalating complexity, and diverse conflicts, the tension between the capacity to shape outcomes and the humility to learn must not only be acknowledged, it must be deliberately and continuously managed.

We're not just dealing with wars between states. Conflicts now span ideologies, information spaces, cultures, and economic interests. There's a wide range of actors with different motivations, from state-sponsored hackers to grassroots movements. This diversity makes consensus more elusive. It has to be actively managed through leadership that fosters humility, institutions that reward learning, and feedback loops that keep systems responsive. This is especially important in global governance, corporate decision-making, and even individual leadership. The faster the world moves, the more dangerous it is to act decisively without understanding deeply. It's not just about us exercising power, we need to evolve along with the systems we are trying to shape.

Sine-curves are a universal pattern in natural, social and individual processes. They help us to see fluctuations not as a failure, but as part of a rhythm. If you recognize them, you can use them consciously, for example, to get through crises better or to use high phases efficiently. However, people don't just move through eternal ups and downs, they go through rhythms, transcend them and find new paths within them.

The rhythm of life can be represented in waves in nature, body, society and mind. These waves are not dead ends. Above all, they are carriers of information, maturity and change. Human beings respond to the rhythm when they think about it, not mechanically but creatively. In philosophy, this is understood as resonance. Existence speaks, man responds. This creates connection, deepening, awareness. You can adjust to the curves in the course of life and make the best possible use of them. The sine of life is not a prison. It is a signpost for resonance, maturation and freedom.

The human being does not get stuck in the sine-curve system. He expands until he accepts what is, until he resonates with what is. The rhythm is constantly followed by new beats and tones. Each beat holds the possibility of going beyond it. The sinus movement remains intact. Nevertheless, it spirals outwards and expands. Development becomes possible through reflection, intuition, experience, not despite, but through the rhythm. The rhythm remains temporary, but consciousness grows.

While sine-curves have important properties and applications in mathematics, they are only one building block within a much broader field of experience and meaning. Individual worlds of experience encompass subjective impressions, cultural backgrounds, personal interpretations and emotional experiences that go far beyond pure mathematical description.

The idea of cyclical movements, rise, fall and return offers a structuring perspective on processes in life, society and the psyche. However, individual experience goes far beyond these regularities. Human experience is not only rhythmic, but also spontaneous, irrational and unique. Biographies do not necessarily follow sinusoidal patterns; some lives are fragmented, some straightforward, others chaotic. The subjective impression of time, change and development is highly individual. There are also states of stagnation, leaps, standstills or explosions that defy sinusoidal logic. The sine curve can have an explanatory or organizing effect. However, it cannot depict life as it is lived. Because people are more than patterns, they are beings of meaning, not just patterns of movement. The sine metaphor can be helpful for certain issues such as recovery, performance or social dynamics. However, it loses its significance when it comes to questions of existence, meaning and uniqueness.

Not all learning is purely cognitive. Deep, transformative learning occurs where the experience of meaning is set in motion, when that which carries inner meaning begins to waver, changes, is questioned or sensed anew. The sine-curve becomes an up and down of the perception of meaning, which gives life its depth and tension. Those who do not close themselves off to this dynamic and engage with it, will become smarter, more aware and perhaps even wiser. The learning curve that results from experiencing a crisis of meaning is steeper. Anyway, it is more sustainable than any purely academic or instrumental knowledge.

Learning is more than storing facts. Anyone who has ever experienced a life crisis, lost a great love or gained a new worldview knows that deep learning begins where the head alone is no longer sufficient. It starts where something in the innermost part begins to move. Where what has made sense suddenly comes into question and thereby gains new meaning. In this process, our interior often resembles a sine curve. Up and down of sensation, an alternation between clarity and doubt, between certainty and reorientation. Sometimes we feel elated, sometimes we stand in the valley and wonder how we got here, yet both go together. Without fluctuation no change, without movement no depth.

Transformation has its own rhythm, and it is rarely comfortable. When beliefs dissolve, values shift or new experiences challenge old truths, we often feel insecure and yet that is where learning takes place. Not in the sense of more knowledge, but more humanity. Coaches and therapists already know this. They do not accompany people in order to give them quick answers, but to help them not to sink into this up and down of the inner meaning. Change, which really carries, occurs where something is noticeably shifting, where not only the head but also the heart has to learn. The sine-curve as a symbol of learning reminds us that no human being lives in a constant state and does not have to live. Depth, real knowledge is rarely created in euphoria alone. It needs questioning, stumbling, finding again and sometimes even the detour through nothingness. Perhaps we should also expect more often in education, in society, in our own everyday lives that learning is not linear, but like life itself rhythmic, fluctuating, meaningful.

Those who do not close themselves off from this dynamic, but go along with it, become wiser, more aware, perhaps even wiser. The learning curve that results from a lived crisis of meaning is steeper and at the same time more sustainable than any purely scholastic or instrumental knowledge. The art of reading sinusoidal curves is greatly underestimated in troubled times, not on paper, not in formulas, but in real life. Those who have learned to interpret wave movements, in politics, economics, their own psyche, quickly realize that not every low is a disaster and not every high is a triumph, but part of a cycle. The sine curve is simple, almost elegant; up, down, up, down, in regular momentum; it looks harmless. But if you look closely, you see in it an original principle: the interplay of tension and relaxation, rise and retreat, expansion and reduction. This applies not only in physics, but also in our thinking, feeling and acting.

This art begins with observation: where are we on the wave? Is what we experience a natural valley or a structural crash? Is a peak lasting or already the harbinger of a new downturn? Anyone who can analyze sine curves learns to distinguish between real alarm and cyclic tremor, between chaos and dynamics. This applies to economic trends as well as to social moods or personal developments. Those who see only the threatening in a change remain reactive, but those who recognize the wave movement become capable of action and patient. Even more interesting is the second step, the interpretation. Because what makes the sinusoidal curve so exciting is not its uniform course, but its meaning: What does a low? crisis? cleansing mean? Preparation? And what is a high? Success? Harvest? Exuberance? In the interpretation lies the real treasure. Those who not only measure the waves, but also read them, can make stories out of them for themselves, for others, for societies.

Of course, not everything follows beautiful patterns; not every crisis is part of a plan, but surprisingly much moves in rhythms. The sine curve reminds us that change is not always threatening, but simply natural. Who understands this dynamic loses less energy in resistance and gains more strength in dealing with what comes. So the great art is not to control the curve, but to read it and live with it.

2. WHY THE SINE-CURVE IS NOT LIFE

Copied from nature, refined in mathematics and transferred to psychology and culture, the sine-curve is a powerful symbol of cyclical growth and decay. It can be found in electrical voltage, in the changing seasons, in stock market prices and in the mood of people themselves. Rise, peak, fall, depression - and all over again.

As plausible and reassuring as this pattern may seem, it has almost become a defining model of thought in the modern interpretation of the human condition. And yet, it is precisely in its perfection of form that its limitations lie. Because man is not just a wave being, not just a particle in an eternally recurring cycle. His experience, his consciousness, his existence, all of this goes beyond the model.

The sine curve is not to be understood as an explanation of the world, it is only a partial view, an auxiliary construction. It is a useful sketch and not a map of existence. The idea of cyclical movements has a long history. It is reassuring because it promises orientation. What rises will fall, what sinks can rise again. Burnout gives way to regeneration, winter to spring, political crisis to reconstruction. The sine-curve suggests that everything has a natural rhythm. Many biological, social and economic phenomena follow such wave patterns.

But what happens to experiences that don’t repeat themselves, that get out of step? What about biographical ruptures, unprocessed traumas, existential upheavals that cannot be repeated, that mark a turning point? What about people whose development does not increase, but stagnates, collapses or is diffuse, instead of sinusoidal and even chaotic or fragmented? Human beings are full of coincidences, characterized by crises and creativity in equal measure. His life is not a rhythm, but a struggle. Not a dance, but a feeling.

Every model of thought carries the danger of reduction. What fits into a diagram seems tangible. This very comprehensibility is deceptive. Anyone who sees everything as a wave overlooks the singular, the unpredictable. They only see development in phases, not in leaps. They think of life in terms of regularity, when in fact it is disruption. However, reality does not always follow these models. History isn't just a series of gentle crests and troughs. It's full of ruptures, moments that break the rhythm, events that no model predicts, individuals who reshape everything. Waves can teach us about trends, but they often miss the singular, the black swan, the personal revolution, the unexpected insight. In the obsession with the average, we forget the outlier.

Nature does not always evolve gradually. Neither do societies. Neither do we. Evolution proceeds through leaps, punctuated equilibria, as in biology, where long periods of stability are suddenly upended by bursts of rapid change. Technology doesn’t just progress in iterations; sometimes it jumps. Cultures don’t always drift; they collide. Those who only see waves can’t see the singular, the moment that doesn’t repeat, the person who doesn't fit, the leap that wasn’t supposed to happen. And yet, it is the singular that often defines our lives, the choice that changed everything, the encounter that shifted perspective, the event that reset the timeline. The sine-curve is a useful tool, for example in therapy, education and time management. However, when it becomes the fundamental narrative of life, it devalues the existential depth of human experience. These are valid, even essential applications. They help us structure understanding and build resilience. Strangely enough, problems arise when the sine curve becomes more than just a tool, when it becomes a comprehensive representation of human life. Because life isn’t just a pattern of repeatable cycles. It contains ruptures that don’t return, losses that aren’t followed by compensating gains, insights that arrive without precedent, and existential shifts that don’t fit any curve.

People don't just live in waves, but in relationships. We are called by others, by the unknown, by beauty, by suffering. And it does not always answer regularly, not always predictably. It does not move mechanically to the rhythm of the world, but lives in constant dialogue with itself, with others, with the world, with what is present and what is absent. It is summoned not only by voices, faces, disasters, or beauty, but by something greater than itself. That which is not tangible, cannot be named, cannot be grasped and yet is there. It is about presence, depth, transcendence.

Human beings are not only biologically, psychologically and socially responsive, they are above all spiritually responsive. When they are called upon by others, by the unknown, by beauty, by suffering, their response does not follow a pattern. It is usually tentative, fragile, hesitant, sometimes loud, sometimes just silence. It is in this ability to respond that lies what elevates man beyond mere life. He questions, he searches, he doubts, and in all of this he does not react particularly to what he encounters, but much more to what surpasses him. In the end, it is not just the rhythm of life, not just success and crisis, tension and calm, waves and cycles. At the end is the relationship. This relationship is not mechanical, not necessary, not predictable. It is open and yet real. It happens through listening, responding and allowing oneself to be touched. People “reason” with the world. They don't swing to the beat, they just swing in time. It reacts, transforms, changes, not always in periods, sometimes in discharges, falls, standstills or in sudden insights that defy any curve. It reacts, transforms, changes, not always in periods, sometimes in discharges, falls, standstills or in sudden insights that defy any curve.

Nevertheless, people are seen as teammates in a wave-like process, embedded in cycles of highs and lows, of activity and rest, of success and failure. So this model also has its justification. It helps to structure processes, de-dramatize crises and classify phases of life. Despite all this, people are more than just biological, social or psychological beings. They are a responding being. And in this ability to respond lies something that no cyclical model can ever fully grasp, the openness of the human being to the other, to the divine.

The sine-curve is useful for observation, but that is not enough. It cannot explain touch, grace, an inner call, a sense of premonition or transformation. Where models end, the space of meaning begins. And meaning is always relational. Humans are creatures that not only recognize patterns. They also react to meaning. And they experience this meaning in their encounter with the incomprehensible. What if being human did not mean functioning, but reacting, not to be able to control everything, but to be touched, not to act alone, but to know that he is called. Then life would not be a succession of phases, it would even be a space of encounter in which we learn to listen and be amazed. It is a space in which a resonance with the supernatural, or if you like with the divine, can take place in the midst of everyday life, in silence. Self-reflection as a practice of self-development is therefore at the heart of this space. It serves to recognize one's own values and boundaries, not to harden them, but rather to consciously respect and explore them at the same time. Borders do not appear as absolute barriers. Rather, they are an invitation to transformation. Between action and pause, life unfolds in a rhythmic balance that finds its fulfillment neither in blind energy nor in mere contemplation. The ability to combine humility and energy becomes the ethical standard for mature action.

At the same time, the question of origins is not merely a cosmological or theological problem. It becomes a fundamental existential positioning. Where do I come from? What sustains me? What calls me? The origin is not thought of as a fixed point, but as a source and possibility from which the human being springs anew in every encounter with himself and the world. In the midst of complexity, disruption and pattern formation, this question urges to be asked, not as a scientific investigation, but as an existential necessity. These questions are not about the past alone. They are not answered by simply pointing to a birthdate, a genome, a history, or even a myth. Instead, they point to something deeper, to origin not as a moment, but as a living, generative source.

To ask about origin is to ask what grounds and animates us, not just once, but continuously. It's about not just looking back, but looking inwards and forwards with the same vigor. It is to remain open to the mystery that we are not entirely self-made, that something beyond will and intention sustains our becoming. In this light, every authentic encounter with ourselves, with others, with the world becomes an invitation to reconnect with origin, to draw from the deep well of what calls us into being. This shifts our orientation. Instead of merely managing life’s phases or navigating disruptions, we are asked to listen to the source that never ceases to offer itself. This origin is absolutely not static, it is fundamentally dynamic at its core. It does not explain, but it justifies. It does not dictate, but invites. Placed within the larger argument, this reflection on origin adds depth and verticality. This adds the dimension of meaning, of where we draw our life from, and how we renew it.

3. THE ROLE OF CREATIVITY

Does intuition seem like a foreign body when it does not obey a fixed plan, cannot be forced upon us and yet is crucial for innovation, meaning, change and the future? At the same time, people experience two opposing movements within themselves, the call for structure, security and routine and the longing for inspiration and freedom of thought. This tension is not a flaw. It is a basic condition of creative processes. An interesting perspective arises as soon as we understand this tension as a movement instead of a contradiction in the image of the sine curve. It defines the rhythmic ups and downs, the alternation of tension and relaxation, of concentration and detachment, of training and performance. In this movement of the curve, a person can oscillate between the spheres of training reality and the creative approach and thus become creative.

Seen in this light, the sine-curve is more than just an abstract diagram. It is a principle of life, a metaphor for the pendulum between activity and regeneration, concentration and openness, control and devotion. No artist, no thinker, no musician creates either from constant effort or from play and intuition alone. It takes both and the transition between them. In the movement of the curve, a person can swing between structured reality and creative openness and it’s in this dynamic space that creativity is born.

But then there is the other space of the creative process. Here the rules of association, spontaneity and the courage to deviate apply. Creating something that is meaningful is only possible if a sounding board has first been laid through practice, attention and inner maturation. This act is a leap, often unexpected, sometimes even within the realm of the plannable. This is only possible because people have learned to make themselves ready by preparing, even by letting go. The pattern of success lies precisely in the movement of change, not in persistence, not in pure impulse, it is drawn in the rhythm of change.

The alternation of tension and relaxation, depth and ascent reflects what characterizes creativity. Its advocates focus on the ability to change while at the same time maintaining the depth of the movement of views. Creativity describes four interrelated phases that unfold cyclically rather than linearly and whose respective quality is decisive for maintaining quality.

The first phase is characterized by focus and structure. This is where practice, repetition and the internalization of forms take place. In this phase, creative work needs boundaries, methods and tools. Discipline is not a contradiction to creativity, it is its breeding ground. It makes the mind alert and ready. People align themselves, focus their energies, shape the material that will later become permeable. The tension is followed by a necessary break, the letting go. This phase is not inactive, it is receptive. It creates space. Sometimes it begins with doubt, sometimes with a feeling of emptiness. This is precisely where the intermediate field arises as an inner opening for what does not want to be done and yet wants to be received. Withdrawal here is not an escape, it is an act of availability. In this phase, the person becomes quiet and can therefore listen.

Now one dives into the depths of what is not yet available. This is where intrusions, ideas, visions happen. Not out of the will, mainly out of contact with the other, with the inner, the unknown, the meaning. It is a time of resonance with the world, with oneself, perhaps with the divine. What happens here cannot be created, only allowed. Intuition, inner images, jumps of thought arise from a deep connection to the non-tangible. Now the individual returns, with something new in his hand, heart or head; the received gene wants to be formed, shaped, translated. What was intuitively perceptible is translated into speech, image, sound or movement. This phase requires decision and also the courage to limit. The chaos is ordered, not suppressed, at best shaped.

Human beings live neither in constant equilibrium nor in linearity. They need the tension between the forces that challenge, divide, move and change them. These tensions are not accidental. They are constitutive, they make human activity possible in the first place. They are often creative tensions in which the new grows. Meaning is formed in them. They bring about change, personally, socially and spiritually. They bring about change on a personal, social and spiritual level.

In this context, the sine curve is not just a functional model. It is an existential image for the human being as a process, a model that is not aimed at balancing, but at shaping opposites. People do not live in stable conditions. They live in movement, in transitions, in change. What distinguishes them as human beings is not perfection or uniformity, but the ability to live with tension, not destructively, but creatively. Between the poles of his existence of body and mind, inside and outside, freedom and responsibility, this world and transcendence, a space is created that is not harmonious, but fruitful.

The human thus reveals himself as a being in creative tension. This tension is not a disturbance, merely the driving force of his becoming. The model of being human in creative tension is not a psychological program, it is an existential image of life as a response process. Humans don’t have to be harmonious, perfect or constant. They can live between poles and find depth precisely in this. He is not what he has, he finds himself in the movement between tension and resonance.

It is precisely in moments of idling, when external activity
