QUANTUM DIALECTIC PHILOSOPHY

PHILOSPHICAL DISCOURSES BY CHANDRAN KC

The Grand Bifurcation of the Living World into Animal and Plant Kingdoms in The Course of Biological Evolution

In the worldview of Quantum Dialectics, life is not conceived as an anomaly that stands apart from the rest of matter, nor as a supernatural occurrence inexplicable by material processes. Rather, life is understood as the highest known manifestation of the dialectical motion of matter itself—a dynamic equilibrium in which the opposing forces of cohesion and decohesion attain a new level of organized balance. Cohesive forces represent the tendency of matter toward structural stability, integration, and persistence—the gravitational, chemical, and informational drives that hold systems together and preserve their identity across time. Decoherent forces, by contrast, represent change, transformation, and metabolic flux—the disintegrative yet creative tendencies through which structures dissolve, reorganize, and evolve into new forms.

Life emerges precisely at the threshold where these forces achieve a higher synthesis. It is the quantum leap of matter into a form of being that internalizes contradiction: a system that is simultaneously stable and unstable, cohesive and decohesive, identical and changing. In living organisms, energy and information are not merely exchanged with the environment but actively regulated, producing the remarkable phenomena of metabolism, growth, reproduction, and adaptation. Thus, from the standpoint of Quantum Dialectics, the origin of life signifies the emergence of matter capable of self-reference—matter that reflects upon its own energetic and structural conditions and reorganizes them in the pursuit of continued existence. Life is, in this sense, the self-organizing consciousness of matter—not yet mental, but already dialectically intelligent.

Within this grand continuum of self-organizing evolution, there occurred one of the most momentous transformations in the history of the biosphere: the great diversification of the living world into the plant and animal kingdoms. This bifurcation was not a mere taxonomic branching in the tree of life, nor an arbitrary division of morphological types. It was, rather, a fundamental dialectical bifurcation within the life-process itself, a differentiation of the universal metabolic code into two opposite yet complementary poles of being. On one side arose the autotrophic organisms—those capable of synthesizing their own organic compounds directly from inorganic sources by harnessing the cohesive potential of sunlight. On the other side evolved the heterotrophic organisms—those that, by feeding on the organic products of others, specialized in the decohesive transformation and liberation of stored energy.

Through this differentiation, the life-process attained a new order of planetary organization. The autotrophic line—culminating in plants—embodied the cohesive pole of evolution, functioning as the great condensers of solar energy into the stable coherence of organic matter. The heterotrophic line—culminating in animals—embodied the decohesive pole, transforming that stored energy back into motion, sensation, and awareness. Together, these two realms formed the dialectical metabolism of the biosphere, in which energy flows cyclically from sunlight to structure, from structure to movement, and from movement back to dissolution and renewal.

The divergence between plants and animals therefore represents, in the light of Quantum Dialectics, not a division of life but its completion—the materialization of the universal dialectic of cohesion and decohesion at the biological level. Through this grand diversification, the universe evolved a living system capable of maintaining 

In the earliest chapters of Earth’s biological history, life did not yet bear the clear distinctions that we now recognize between plants, animals, or even microorganisms. The first living entities were likely chemoautotrophic protocells, arising in a world where the boundary between the inorganic and organic was still fluid, a dialectical twilight zone where matter was learning to organize itself into the living. These primordial forms of life subsisted on the chemical gradients available in their environments—volcanic vents, mineral interfaces, and primordial oceans rich in reactive compounds. Through complex catalytic cycles, they absorbed inorganic molecules such as carbon dioxide, hydrogen sulfide, and ammonia, and transformed them into organic molecules capable of self-assembly and replication.

In the language of Quantum Dialectics, this process represented the conversion of cosmic decohesion into material coherence. The vast, unstructured energy flux of the cosmos—solar radiation, geothermal heat, and chemical disequilibria—was captured and condensed into organized patterns of molecular structure. Life, in its earliest appearance, was thus an act of dialectical synthesis, where energy and matter entered into a new mode of relation: not one of passive reaction, but of self-sustaining transformation. The earliest organisms became localized vortices of order, continuously forming and reforming themselves through a reciprocal exchange with the environment.

Yet even in this primitive unity of metabolism, the seeds of contradiction were already present. Every living system, by its very nature, must maintain structural stability—the cohesive tendency that preserves its internal organization against the entropic pull of the external world. At the same time, it must also sustain energetic transformation—the decohesive process through which it absorbs, converts, and expels energy to remain dynamically balanced. These two tendencies—to remain and to change, to preserve and to transform—are not merely mechanical opposites but the constitutive dialectical poles of life itself. Without cohesion, life would disintegrate into chaos; without decohesion, it would stagnate and die.

This inner contradiction between stability and transformation became the very engine of biological evolution. As early protocells diversified and adapted to varied environments, some lineages accentuated the cohesive pole of existence, evolving mechanisms to synthesize and store energy, thereby achieving autonomy from external organic sources. These became the precursors of autotrophic life, the ancestors of plants and photosynthetic organisms. Others emphasized the decohesive pole, evolving the ability to extract energy by breaking down existing organic molecules, leading to the rise of heterotrophic forms, the progenitors of animals and other consumers of life’s synthesized products.

From this single contradiction—the need to preserve internal structure while transforming energy—arose two grand evolutionary strategies, two directions of dialectical resolution that would shape the entire history of the biosphere. Autotrophy embodied the cohesive synthesis of life’s energy base, converting radiant or chemical energy into the stable coherence of organic substance. Heterotrophy, its dialectical counterpart, embodied the dynamic release of that stored energy into mobility, perception, and complex behavior. The plant and animal kingdoms thus emerged not as accidental outcomes but as dialectical necessities, born from the primordial contradiction inherent in the very definition of life.

In this light, the ancient unity of life did not vanish with its diversification—it became richer, more differentiated, more dialectically self-conscious. The autotrophic and heterotrophic lineages represent not two separate worlds but two complementary expressions of one universal process: the rhythmic pulsation of matter between condensation and liberation, between the fixation of energy into form and the transformation of form into motion. The entire drama of biological evolution can therefore be understood as the unfolding of this primordial contradiction within life, a creative tension through which the cosmos continues its self-realization in the living, breathing, evolving biosphere.

The emergence of autotrophy marked one of the most revolutionary transitions in the evolutionary dialectic of life. In this strategy, living matter achieved the remarkable capacity to internalize the synthesis of its own organic molecules from inorganic substrates, thereby becoming self-sufficient in energy and substance. The most refined manifestation of this process is photosynthesis, wherein chlorophyll-bearing organisms capture the energy of sunlight—one of the most decohesive and diffusive forms of energy in the cosmos—and condense it into the structured chemical bonds of glucose and other organic compounds. In the language of Quantum Dialectics, this is the triumph of the cohesive pole of life: the condensation of dispersed radiant energy into the coherent order of biomolecular architecture.

Through this process, plants and other autotrophic organisms became cosmic condensers—systems that absorb the vast, chaotic radiation of the sun and reconstitute it into the stable, usable patterns of living matter. The chloroplast, as a quantum engine of cohesion, translates photonic flux into chemical coherence, embodying at the cellular level the universal law of the dialectical transformation of energy into structure. Each leaf, each blade of grass, becomes a living mirror in which the universe organizes its own light into form. The autotrophic organism thus stands as a symbol of the universe’s capacity for self-consolidation, transforming decoherence into coherence, chaos into order, energy into life.

Yet, as in all dialectical processes, every synthesis gives rise to its negation. Out of the coherent stability of autotrophic life emerged the heterotrophic strategy—the dialectical counterpart that inverted the very logic of existence. Heterotrophs no longer captured energy directly from sunlight; instead, they evolved to liberate energy stored in the organic molecules synthesized by autotrophs. This was the emergence of a new kind of life—decohesive life—specializing not in the creation of matter but in its mobilization and transformation. In these organisms, the emphasis shifted from synthesis to motion, from conservation to release, from spatial fixation to temporal activity.

Animals, as the culmination of the heterotrophic line, became cosmic transducers. They transformed the cohesive potential embodied in plant matter into the dynamic forms of movement, sensation, and cognition. Through respiration and metabolism, they reintroduced the condensed energy of photosynthesis into the circulatory stream of the biosphere. Each heartbeat, each neural impulse, each act of locomotion is a dialectical conversion of coherence back into decoherence—a liberation of stored potential into kinetic actualization. Thus, animals represent the decohesive pole of the universal life-process, translating the stillness of plants into the restless vitality of motion and awareness.

The relationship between autotrophy and heterotrophy is therefore not one of opposition but of reciprocal unity. They form two poles of the same universal metabolic circuit—two phases in the dialectical rhythm through which life sustains itself on a planetary scale. Plants embody the centripetal movement of energy, drawing the radiant flux of the cosmos inward and binding it into molecular form. Animals embody the centrifugal movement, releasing that bound energy outward into kinetic and cognitive expression. Between these two poles, the biosphere achieves its quantum coherence—a self-regulating cycle of synthesis and catabolism, rest and motion, order and flux.

In this cosmic choreography, autotrophy and heterotrophy together form the living metabolism of Earth—the great respiration of the planet. The still, green photosynthetic world breathes in the decohesive energy of sunlight, while the mobile, sensing animal world breathes it out again through the pulse of life and consciousness. What we call “nature” is, in truth, the dynamic superposition of these two dialectical processes, continually resolving and regenerating each other. Through their inseparable interplay, the biosphere becomes a living totality, a planetary organism where the cohesion of light and the decohesion of motion coexist in perfect dialectical balance, sustaining the continuity of life and the evolution of consciousness.

The great evolutionary divergence between the plant and animal kingdoms was not merely an outward differentiation of form or function; it was a deep molecular and cellular dialectic, a reorganization of the very logic by which living systems process energy, matter, and information. From the standpoint of Quantum Dialectics, this bifurcation unfolded across several quantum layers of biological organization—molecular, cellular, and systemic—each expressing the universal contradiction between cohesive and decohesive forces in its own mode. Through this layered differentiation, life achieved an unprecedented degree of internal specialization, giving rise to two complementary modes of existence that together sustain the planetary metabolism of the biosphere.

At the molecular and cellular layer, the distinction between plants and animals is epitomized in the contrasting architectures of chloroplasts and mitochondria, the twin engines of biological energy transformation. In plants, the chloroplast embodies the cohesive principle of energy condensation. Through the process of photosynthesis, chloroplasts capture the decoherent energy of sunlight—pure radiant flux—and convert it into the stable chemical bonds of carbohydrates. This transformation represents one of the most refined expressions of the universal law of energy-to-matter conversion, where light, the most ethereal and diffusive form of energy, is internalized into the molecular coherence that sustains living structure.

In contrast, animals evolved mitochondria as decohesive energy-liberating centers, where stored organic molecules are oxidized to release energy in the form of ATP, the currency of motion and metabolism. The mitochondrion is the inverse mirror of the chloroplast—a quantum engine not of condensation but of liberation, converting the cohesive stability of organic matter back into the dynamic flux of usable energy. At this cellular level, the two organelles form a dialectical pair, symbolizing the twin poles of the universal life process: cohesion and decohesion, synthesis and release, condensation and dissipation. It is as if, within every living cell, the cosmic dialectic of energy and matter is reenacted in miniature, maintaining the rhythmic balance upon which all biological order depends.

This same polarity extends into the realm of metabolism, where the essential contrast between plant and animal life becomes one of anabolism versus catabolism. The metabolism of plants is fundamentally anabolic—an ongoing construction of complexity from simplicity. Through the synthesis of carbohydrates, lipids, and proteins from inorganic or basic precursors, plants embody the centripetal tendency of life: to integrate, to accumulate, to build and preserve. Animals, by contrast, operate primarily through catabolism, the reverse process of breaking down complex molecules into simpler forms to release energy. Their metabolic drive is centrifugal, dispersing stored order into kinetic expression—movement, heat, and thought.

In this metabolic polarity, we see a biological reflection of the universal dialectic of integration and disintegration. Just as galaxies condense and collapse, stars ignite and decay, or atoms form and release energy, so too does life oscillate between anabolic creation and catabolic dissolution. The continuous interchange between these two poles—plants synthesizing the fuel that animals consume, and animals returning carbon and nutrients to the soil and atmosphere—constitutes the self-sustaining circulation of life’s coherence. Each side presupposes and regenerates the other in an endless dance of mutual transformation.

At the systemic layer, this dialectical divergence manifests as a contrast between immobility and motility, passivity and activity, sensation and consciousness. Plants, as cohesive systems, are anchored in space, rooted to the Earth, drawing sustenance and information from their surroundings through gradients of light, gravity, and water. Their mode of existence is one of spatial integration, establishing stability and order within the ecological field. They perceive the environment through distributed sensitivity—responding to sunlight, moisture, temperature, and chemical cues—but their awareness is collective, diffused, and rhythmic rather than individualized or mobile.

Animals, on the other hand, embody the decohesive logic of mobility and active adaptation. By evolving muscular and nervous systems, they acquired the capacity to pursue equilibrium dynamically, seeking and shaping their environments through movement and perception. This transition from passive adaptation to active exploration represents a quantum leap in decohesive complexity, enabling life to externalize its contradictions and resolve them through behavior and cognition. The emergence of motility was not a mere mechanical adaptation but the biological foundation of consciousness—for in moving, life began to anticipate, to remember, and to choose. Through the animal line, the dialectical tension between organism and environment became internalized as awareness, giving rise to the first glimmers of subjective experience.

Thus, from the molecular dance of chloroplasts and mitochondria to the planetary ballet of photosynthesis and respiration, the plant–animal divergence reflects a universal dialectical principle: the constant interplay of cohesion and decohesion, synthesis and motion, order and transformation. Each kingdom embodies one aspect of the same cosmic rhythm, and together they maintain the quantum coherence of life on Earth. Plants build the body of the biosphere; animals animate it. Plants capture the stillness of light; animals release it as movement and thought. In their eternal reciprocity, the universe contemplates itself—rooted in one form, moving in another—breathing through the dialectical lungs of life.

In the framework of Quantum Dialectics, the processes of photosynthesis and respiration are not independent biochemical reactions confined to different classes of organisms but complementary moments of a single universal dialectic—the ceaseless transformation of energy into matter and matter back into energy. They represent two opposed yet interdependent movements in the grand rhythm of the biosphere, through which the Earth as a living system maintains its dynamic equilibrium. Photosynthesis embodies the cohesive phase of this rhythm—the condensation of cosmic decoherence into biological structure—while respiration embodies the decohesive phase, the release and re-circulation of that condensed potential into the field of life’s activity. Together they form a dialectical metabolism: the breathing of the planet itself.

In photosynthesis, the most fundamental act of cohesion in the living world occurs. Plants, algae, and certain bacteria capture photons—the quanta of radiant, decohesive energy streaming from the sun—and convert them into coherent chemical bonds within organic molecules such as glucose. This transformation represents not merely an energy exchange but a profound ontological transition: the transformation of the immaterial and diffusive into the material and structured. Within the chloroplast, photons are absorbed by pigment molecules, their energy driving a series of redox reactions that separate electrons from water, releasing oxygen as a byproduct and fixing carbon into stable sugar molecules. Through this process, light becomes life—a radiant potential reconstituted as living coherence, a fragment of the sun’s decohesion crystallized into the cellular architecture of Earth.

Respiration, in turn, represents the dialectical negation and completion of this process. Within the mitochondria of plant and animal cells alike, the glucose molecules formed by photosynthesis are broken down through oxidative pathways, releasing the stored chemical energy as usable kinetic and thermal flux. This liberated energy fuels the myriad motions of life—muscular contractions, neural signaling, biosynthesis, and thermoregulation—transforming the stillness of stored sunlight into the dynamism of living activity. What photosynthesis binds together, respiration unbinds; what the plant condenses, the animal disperses. Yet this apparent opposition conceals a deeper unity: the released energy of respiration reenters the cycle as the driving force for further synthesis, while the carbon dioxide and water produced become the raw materials for the next photosynthetic act.

When viewed dialectically, photosynthesis and respiration thus appear as the inhalation and exhalation of the biosphere—two poles of one continuous metabolic circuit that sustains the planetary web of life. Each process negates and preserves the other in an endless rhythm of transformation: cohesion giving rise to decohesion, and decohesion returning to cohesion. Through this self-sustaining loop, the biosphere achieves homeostatic balance, maintaining the global composition of gases, the recycling of nutrients, and the flow of energy through all ecosystems. It is a planetary-scale feedback system, finely tuned yet dynamically fluctuating—a living manifestation of quantum equilibrium, where stability emerges not from stasis but from the perpetual oscillation of opposites.

From this perspective, the plant and animal metabolisms are not antagonistic but quantum-entangled expressions of the same universal process. The glucose molecule synthesized in the chloroplast and oxidized in the mitochondrion embodies the perfect dialectical unity of condensation and release, potential and actualization, order and flux. Every breath an animal takes is an act of participation in this cosmic rhythm—an exchange of coherence and decoherence that binds the individual organism to the planetary totality. The oxygen inhaled was exhaled by plants; the carbon exhaled returns to them. Through this reciprocal exchange, the Earth maintains its dialectical wholeness, ensuring that energy and matter remain in continuous circulation rather than accumulation or exhaustion.

Thus, in the light of Quantum Dialectics, photosynthesis and respiration are not merely biochemical opposites but cosmic counterparts—the two alternating heartbeats of the living planet. Together they constitute the biosphere’s self-organizing intelligence, its capacity to transform entropy into order and order back into creative flux. Through their perpetual interplay, the universe remembers itself in the pulse of life, where sunlight, carbon, and breath unite in the ever-repeating cycle of coherence and liberation—the dialectical metabolism of existence itself.

The evolutionary bifurcation between plants and animals did more than shape the physical diversity of life; it laid the groundwork for the emergence of consciousness itself. From the perspective of Quantum Dialectics, consciousness is not an abrupt or miraculous addition to matter but the progressive internalization of contradiction—the growing capacity of living systems to register, process, and respond to the dynamic tensions between themselves and their environment. In this light, the plant–animal divergence represents the two primary dialectical paths through which matter began to evolve awareness: one rooted in cohesive stability and spatial integration, the other in decohesive motion and temporal anticipation. Together, they constitute the twin origins of sentience—the cosmic awakening of matter to itself through life.

Plants, as embodiments of the cohesive pole of life, express a mode of intelligence that is distributed, non-localized, and collective. Their awareness does not arise from a central nervous system but from the intricate web of bioelectrical, biochemical, and photoreceptive networks that permeate their tissues. Every cell in a plant participates in sensing and responding to the environment, from the detection of light gradients by chloroplasts to the regulation of growth through hormonal signaling and electrophysiological communication. This form of phototropic intelligence enables plants to orient themselves toward sources of light, water, and nutrients, to anticipate day and night cycles, and to modulate their internal states in harmony with the surrounding ecosystem. Their awareness is spatial rather than temporal—an expansive, field-like sensitivity that perceives the world as gradients of light, gravity, and chemical potential.

In contrast, animals embody the decohesive concentration of perception. Their evolution marks a quantum leap in the localization and acceleration of awareness, where sensation becomes centralized, processed, and transformed into action. Through the development of sensory organs, nervous systems, and ultimately brains, animals acquired the ability to integrate information across time and space, to form representations of the external world, and to act upon it intentionally. Whereas plants assimilate light as energy, animals translate light into perception. Their nervous systems fragment the continuous flow of stimuli into discrete signals, which are then synthesized into coherent patterns of experience. This marks the emergence of subjective reflection—the moment when matter, organized as a living nervous system, begins to know its own contradictions and to act upon that knowledge to restore equilibrium.

The plant–animal polarity, therefore, can be interpreted as the dialectical unfolding of the two primordial modes of cognition through which the universe comes to know itself. Plants manifest the objective cognition of light—a mode of knowing grounded in assimilation, synthesis, and stillness. Their awareness is not introspective but ontological: they are their knowing, embodying the cosmic act of condensation by which energy becomes matter. Animals, conversely, manifest the subjective cognition of movement—a mode of knowing grounded in expenditure, differentiation, and change. They know by acting, by transforming energy into motion, by turning contradiction into behavior. Thus, if the plant represents the cosmic act of being, the animal represents the cosmic act of becoming.

Through this dialectical progression, sentience arises as the synthesis of cohesion and decohesion. The calm, integrative awareness of the plant and the dynamic, reflective awareness of the animal are not opposing forms but two complementary expressions of cosmic self-awareness—one rooted in stillness and synthesis, the other in motion and transformation. The evolution of perception, from photosensitivity to thought, mirrors the universe’s own dialectical journey from matter to mind: a process through which the cosmos, in organizing itself, becomes capable of self-recognition.

In this sense, consciousness is the flowering of the dialectic between the plant and the animal. The still leaf turning toward the sun and the animal eye perceiving the world in motion are parallel expressions of the same cosmic intelligence—the one absorbing light into form, the other releasing it into awareness. Through them, the universe learns both to rest in itself and to move beyond itself. And in this rhythmic oscillation between cohesion and decohesion, between being and becoming, the great dialectical continuum of consciousness begins its ascent toward reflection, imagination, and finally self-understanding—the cosmos awakening to its own light.

From the standpoint of Quantum Dialectics, ecology is not merely a study of relationships among organisms but a manifestation of the universal principle of entanglement expressed through the living fabric of the biosphere. The interdependence between plants and animals illustrates how life, in all its diversity, remains bound by dialectical coherence—a dynamic equilibrium of opposing yet complementary processes. In this view, every act of respiration is quantum-entangled with an act of photosynthesis: the carbon dioxide exhaled by animals becomes the raw material for the plant’s synthesis of glucose, while the oxygen released by plants becomes the fuel for the animal’s metabolism. This reciprocity forms a closed energetic and material circuit, a planetary metabolism in which each living act is both autonomous and collective, both individual and universal.

In this ecological entanglement, death and decay are not interruptions but essential moments of renewal. Every organismal death releases stored biochemical potential back into the matrix of life, providing nutrients for autotrophic regeneration. In this way, decomposition becomes the dialectical complement of composition, ensuring the continuous transformation of matter through the biosphere’s living cycles. Just as quantum systems maintain coherence through superposition and exchange, ecosystems maintain stability through reciprocal transformation—each species and process feeding into the next, sustaining the integrity of the whole. Thus, evolution itself is revealed not as a linear ascent from simple to complex, but as an oscillating dialectic between phases of cohesive equilibrium and decohesive innovation. Plant-dominated epochs, characterized by global stability and the expansion of photosynthetic networks, alternate with animal-driven revolutions, where mobility, predation, and consciousness accelerate the reconfiguration of ecological systems.

Even the great evolutionary innovations—symbiosis, parasitism, pollination, and mutualism—are profound expressions of this reciprocal unity of opposites. The evolution of endosymbiosis, which gave rise to chloroplasts and mitochondria, was itself a literal fusion of once-separate organisms into a higher-order coherence—an act of dialectical synthesis written into the cell’s architecture. Similarly, the intricate relationships between flowering plants and pollinating animals exemplify the ongoing dialogue between the cohesive and decohesive principles of life: plants externalize part of their reproductive function into the mobility of animals, while animals internalize plant-derived cues—color, scent, nectar—as stimuli for their own survival. Even parasitism, seemingly destructive, serves a dialectical function: it introduces tension and contradiction, compelling both host and parasite to evolve new strategies of equilibrium, thereby driving the creative transformation of life.

At subtler levels, each kingdom has internalized aspects of the other through evolutionary mimicry and integration. Plants, though sessile, have developed animal-like modes of signaling—electrical impulses transmitted through plasmodesmata, volatile chemical messengers akin to pheromones, and responsive behaviors such as phototropism and thigmonasty that suggest a distributed form of awareness. Conversely, animals have evolved plant-like characteristics of cooperation and symbiosis: the formation of microbiomes, the mutualistic exchange of nutrients with gut flora, and the development of ecosystems that mirror the communal logic of a forest. This ongoing cross-fertilization reveals that no form of life is purely cohesive or purely decohesive; every organism is a composite of both tendencies, continuously negotiating its balance within the web of existence.

When seen as a whole, the biosphere functions as a dialectical super-organism—a planetary entity in which countless individual contradictions resolve into a grand, self-organizing coherence. Energy flows through it as if through a single living body; carbon, nitrogen, and water circulate like blood and breath; and the countless feedback loops of ecology resemble the metabolic pathways of an immense, conscious being. The interdependence of plants and animals, of cohesion and decohesion, of synthesis and transformation, thus constitutes the very essence of Gaia’s living order. The Earth is not a passive stage upon which evolution unfolds—it is an active dialectical totality, continuously creating, negating, and recreating itself through the interplay of all its parts.

In this vision, ecological coherence is evolutionary coherence, and evolution itself becomes the biosphere’s way of thinking—its dialectical reflection of the cosmic process. The entanglement of life forms, the cyclic exchange of energy and matter, and the perpetual balancing of stability and change reveal the universe’s deepest law: that all things live through their opposites and sustain themselves through their contradictions. The plant–animal relationship, in its rhythmic reciprocity, is thus the living embodiment of the universal dialectic—a reminder that life, in its fullest sense, is not competition but coherence, not separation but the endless becoming of unity through diversity.

In the grand narrative of evolution, humanity represents the self-reflexive synthesis of the plant–animal dialectic—the point at which the opposing forces of cohesion and decohesion, stability and transformation, synthesis and motion, converge into conscious mediation. Emerging from the animal lineage, humans inherited the decohesive dynamism of mobility, perception, and cognitive expansion, yet through the mastery of agriculture and ecological symbiosis, they reappropriated the cohesive logic of plant life. By learning to cultivate plants, humans internalized the principle of photosynthesis into their own mode of existence: they began to domesticate the cohesive power of the sun—the very act of condensing radiant energy into structured life. Through agriculture, humanity bridged the ancient polarity of autotrophy and heterotrophy, embedding the rhythms of plant metabolism within the social metabolism of civilization.

At the same time, through technology, humanity extended and magnified the decohesive potential of respiration. Fire, machinery, and industry became the externalized organs of energy release, transforming stored organic and mineral potential into kinetic and thermal force on a planetary scale. The human capacity to liberate energy—to transmute matter, to move mountains, to shape rivers and climates—reflects an amplification of the animal principle of metabolic liberation, now raised to a new level of abstraction and power. Yet, as Quantum Dialectics reveals, every intensification of one pole inevitably generates tension with its opposite. Humanity’s technological expansion, while expressing the creative potency of decohesion, has also destabilized the cohesive equilibrium that sustains life, leading to ecological imbalance and the systemic crises of the Anthropocene.

The human mind itself is a living microcosm of this universal dialectic. Within the brain’s layered architecture, the cohesive faculties of reason, memory, and moral reflection coexist and contend with the decohesive faculties of imagination, desire, and creativity. The former seek order, stability, and continuity; the latter seek change, novelty, and transcendence. It is through the dynamic interplay of these faculties that consciousness achieves self-awareness—a dialectical synthesis of conservation and revolution within thought. The cohesive mind preserves the accumulated knowledge of species and culture, while the decohesive mind negates and transforms that inheritance, generating art, science, and philosophy. Thus, every act of genuine creativity—be it a poem, a theorem, or a social revolution—is the mental equivalent of photosynthesis and respiration combined, transforming the raw light of experience into structured meaning and releasing that meaning back into the collective evolution of consciousness.

In this higher synthesis, humanity becomes the biosphere reflecting upon itself. Through awareness, language, and technology, the human species has internalized the total planetary metabolism, turning it into thought and action. We are, in the truest sense, Earth become conscious of its own processes—a species in which the planet’s cohesive and decohesive principles encounter each other in reflective form. The plant lives by condensing light into matter; the animal lives by liberating that matter into motion; but the human lives by understanding and regulating both. In agriculture, we emulate the plant; in industry, we emulate the animal; and in ecological science and ethics, we attempt to reconcile the two within the self-aware framework of planetary stewardship. Humanity thus stands as the mediating term in the triadic dialectic of life: the synthesis through which the biosphere begins to know, evaluate, and intentionally shape its own evolution.

Yet this synthesis remains fragile and incomplete. The ecological crisis of our time—climate change, mass extinction, and the collapse of natural cycles—arises from the rupture of the delicate dialectical balance that has sustained the biosphere for billions of years. Humanity’s overemphasis on decohesive technological expansion, divorced from the cohesive wisdom of natural self-regulation, has driven the planetary metabolism toward instability. The task of the future, therefore, is not merely technological innovation but dialectical restoration—a conscious rebalancing of the forces of cohesion and decohesion within the human–Earth relationship. This means integrating scientific reason with ecological empathy, industrial capacity with biotic restraint, and technological advancement with moral evolution.

To achieve this, humanity must transcend its narrow anthropocentrism and recognize itself as the mediating consciousness of a larger living totality. In restoring the equilibrium between photosynthetic synthesis and respiratory liberation—between the life-giving stillness of plants and the creative motion of animals—humans can transform from exploiters of nature into its conscious co-creators. Such a transformation would mark the next great leap in evolution: the emergence of a planetary intelligence, a dialectically coherent civilization in which thought and ecology, matter and meaning, science and spirit unite in the higher synthesis of self-aware existence.

In this vision, humanity’s destiny is not domination but mediation—to serve as the reflective bridge through which the universe reconciles its opposites and advances toward greater coherence. The restoration of planetary balance will thus not only heal the Earth but also fulfill the deeper cosmic purpose of consciousness itself: to bring unity to contradiction, to harmonize energy and matter, and to transform life into a living expression of dialectical wholeness.

The grand diversification of life into the plant and animal kingdoms stands not as a random branching in the evolutionary tree but as a cosmic dialectical necessity—a profound expression of the universal contradiction between cohesion and decohesion, structure and flux, being and becoming. Within the evolutionary continuum, this bifurcation represents not a mere biological event but the self-differentiation of the universe’s primary forces as they ascend into the domain of living matter. Through the emergence of autotrophy and heterotrophy—of synthesis and release, of photosynthesis and respiration—the cosmos achieved a new level of dialectical coherence, transforming inert matter into a self-regulating, self-renewing planetary metabolism. The biosphere thus became a living reflection of the cosmic process itself, where energy and matter ceaselessly circulate between condensation and liberation, rest and motion, life and awareness.

In the framework of Quantum Dialectics, this duality is not a separation but a unity-in-motion. The plant and the animal are two reciprocal moments of one continuous becoming, two polar expressions of the universe’s rhythmic self-organization. The plant embodies the centripetal breath of the cosmos—the inward movement that condenses the radiant energy of the sun into structured biochemical coherence. The animal embodies the centrifugal breath—the outward release of that stored potential into kinetic energy, sensation, and cognition. Through the interplay of these two modes of existence, the Earth itself becomes a breathing organism, inhaling and exhaling energy through the twin processes of photosynthesis and respiration. The biosphere, in this sense, is the universe’s lung and mind combined, converting light into life and life into awareness.

This endless alternation between cohesion and decohesion gives rise to the cyclic unity of creation and transformation that defines both the living world and the cosmos at large. Just as the expansion and contraction of stars sustain the dynamics of galaxies, so too the synthesis and decomposition of organic matter sustain the equilibrium of ecosystems. Every atom of carbon that circulates through a leaf, an animal, and back into the atmosphere participates in this universal dialectic of energy and form—a ceaseless metamorphosis through which the cosmos maintains its creative tension and evolutionary direction. In this light, evolution itself is not the accidental product of chance mutations but the manifestation of dialectical law in biological form—the unfolding of the universe’s own self-organizing logic into increasingly complex and self-aware configurations.

The unity of plants and animals, when understood in this dialectical perspective, reveals the deeper ontological harmony of the cosmos. They are not two realms of life competing for existence, but two expressions of the same cosmic principle seeking balance through difference. The plant, rooted and cohesive, embodies the wisdom of being—the power to integrate and stabilize; the animal, mobile and decohesive, embodies the wisdom of becoming—the power to move, to seek, and to transform. Together they constitute the two dialectical lungs of the universe, through which existence sustains itself and evolves toward greater coherence.

Through this grand interplay of opposites, the cosmos becomes self-reflective. In the rhythmic exchange between light and life, energy and consciousness, the universe attains awareness of its own processes. The biosphere is not an incidental by-product of physics and chemistry—it is their culmination and reflection, the point at which the material universe contemplates itself in the form of living systems. When we observe the green of a forest or the flight of a bird, we are witnessing the cosmic dialectic in motion—matter organizing itself into awareness, the universe thinking, breathing, and evolving through the unity of opposites it carries within.

Thus, in the final synthesis, the plant and the animal are not separate creations but complementary expressions of the same cosmic rhythm—the universe breathing in and out, perpetually synthesizing and releasing, binding and unbinding, dying and being reborn. Through the ceaseless dance of photosynthesis and respiration, cohesion and decohesion, the cosmos achieves its living coherence. It is through this dialectical pulse that the universe knows itself—as energy transfigured into life, as life flowering into awareness, and as awareness returning to embrace the totality of existence.

Chloroplasts are highly specialized organelles found in plant and algal cells, responsible for photosynthesis—the process by which light energy from the sun is captured and transformed into chemical energy stored in organic molecules such as glucose.

At the biochemical level, chloroplasts contain chlorophyll, a pigment capable of absorbing photons, primarily in the blue and red regions of the spectrum. When photons strike chlorophyll, electrons are excited to higher energy states, initiating a cascade of redox reactions that ultimately convert carbon dioxide and water into carbohydrates, releasing oxygen as a byproduct.

From the perspective of Quantum Dialectics, the chloroplast embodies the cohesive pole of life’s light interaction. It is the organ of energy condensation, transforming the most diffusive and decohesive form of energy—radiation—into the stable molecular structures of life. In doing so, the chloroplast materializes the unity of light and matter, translating the universe’s radiance into biological order and growth. It represents the centripetal movement of cosmic energy—the “inhalation” of the biosphere.

Melanoblasts are the precursor cells of melanocytes, the pigment-producing cells in animals. They originate from the neural crest, a highly dynamic embryonic structure that gives rise to multiple cell types involved in sensory, pigmentary, and structural systems.

Melanoblasts differentiate into melanocytes, which synthesize melanin—a complex biopolymer that absorbs, scatters, and dissipates light and ultraviolet radiation. Unlike chloroplasts, which utilize light to generate chemical energy, melanocytes use melanin to modulate and protect against excessive decohesion. Melanin converts potentially destructive photonic energy into harmless thermal energy, preventing DNA damage, oxidative stress, and cellular disorganization.

Thus, at the functional and dialectical level, melanoblasts represent the decohesive pole of light mediation. They do not condense light into matter, but rather transform excessive light into harmless entropy, maintaining equilibrium within the animal’s self-organizing field. Melanogenesis—melanin production—can therefore be viewed as the centrifugal counterpart to photosynthesis: instead of trapping energy to build matter, it disperses energy to preserve matter.

When viewed through the lens of Quantum Dialectics, the relationship between chloroplasts and melanoblasts reveals itself as a profound expression of functional polarity within the biological mediation of light. Though they belong to entirely different kingdoms of life, both organelles arise from the same universal necessity: to regulate the flow of photonic energy—the most decohesive and transformative force in the cosmos—so that life may persist in ordered equilibrium. Each represents one pole of the cosmic dialectic of light and matter: the plant’s chloroplast embodying cohesion, and the animal’s melanoblast embodying controlled decohesion.

In plants, the chloroplast serves as a cellular crucible of synthesis, capturing light energy and converting it into chemical bonds. This process, known as photosynthesis, transforms photons—diffuse quanta of radiant energy—into molecular coherence, creating carbohydrates that become the structural and energetic foundation of all higher life. The chlorophyll molecules within the chloroplast absorb specific wavelengths of light, particularly in the blue and red regions of the spectrum, while reflecting green—the visible signature of their cohesive function. Through this intricate conversion, light, the most elusive and decoherent of energies, becomes fixed into the solid architecture of matter. The chloroplast, therefore, symbolizes the centripetal force of the living universe, drawing dispersed energy inward, condensing it into form, and building the very fabric of the biosphere.

In contrast, melanoblasts—the progenitor cells of melanocytes in animals—play an opposite but equally vital role in the dialectic of light. Rather than capturing and storing radiant energy, they produce melanin, a dark polymeric pigment that absorbs and dissipates light, particularly ultraviolet radiation. This process does not build energy-rich structures but rather prevents structural disintegration by neutralizing excess photonic energy. Melanin converts high-energy radiation into harmless thermal energy, thus preserving cellular integrity against the destructive decohesion of light. Where the chloroplast channels the creative influx of energy into order, the melanoblast channels the defensive transformation of energy into equilibrium. Functionally, one may say that photosynthesis is the art of light’s assimilation, while melanogenesis is the art of light’s domestication. Both are indispensable moments in the biosphere’s photonic metabolism—one generating order from energy, the other safeguarding that order from dissolution.

From this perspective, chlorophyll and melanin appear as two dialectical expressions of the same universal function: photon mediation. Chlorophyll transforms photons into biochemical energy, integrating them into the architecture of life; melanin absorbs those same photons to protect that architecture from excess decohesion. Chlorophyll is luminous, reflective, and generative; melanin is absorptive, grounding, and protective. One may therefore regard chlorophyll as the green face of cosmic cohesion, and melanin as the dark face of cosmic resilience—together forming the yin and yang of the living world’s relationship with light.

Their respective energy flows also demonstrate this complementarity. In the plant cell, energy flows inward and upward, from the sun to the molecule, from radiation to form—a process of condensation, or endothermic synthesis. In the animal cell, energy flows outward and downward, from molecule to motion, from form to release—a process of dissipation, or exothermic transformation. Through chloroplasts, light is captured and materialized; through melanoblasts, light is tamed and diffused. This dual circulation mirrors the universal rhythm of inhalation and exhalation—the universe’s breathing through its living forms.

On a planetary scale, the chloroplast establishes the biosphere’s energetic foundation by generating organic matter and oxygen; the melanoblast, in turn, ensures the stability of that biosphere by protecting complex animal forms from photonic chaos. Thus, the chloroplast operates as the macrocosmic regulator of solar input, while the melanoblast acts as a microcosmic regulator of photonic excess. The first transforms light into order; the second transforms light into balance. Their interplay reveals that no life-form can exist without both the creative and protective dimensions of light regulation. Plants and animals, though functionally distinct, are entangled participants in the same cosmic dialogue between energy and structure, creation and preservation.

In evolutionary terms, these two modes of light interaction embody opposing yet interdependent strategies of survival. The plant’s chloroplast represents the organism’s capacity to embrace the sun—to absorb, transform, and build with its energy. The animal’s melanoblast represents the capacity to moderate that same energy—to resist, channel, and survive within its intensity. One expresses life’s faith in light; the other expresses life’s wisdom before light’s danger. The two together form a photonic dialectic: a rhythmic interplay in which the universe not only creates through light but learns to preserve creation through its regulation.

Ultimately, both chloroplasts and melanoblasts demonstrate the self-organizing intelligence of matter—its ability to achieve coherence through contradiction. The plant’s chloroplast and the animal’s melanoblast are not opposites in the dualistic sense, but polar expressions of one integrated process: the cosmic metabolism of light. The chloroplast shows how light can be materialized into living form, while the melanoblast shows how that living form can withstand and adapt to light’s destructive intensity. Together, they define the limits and possibilities of life’s dialogue with the sun, and by extension, with the radiant decohesion of the universe itself.

In this deeper, dialectical sense, the green of the leaf and the darkness of the skin are not separate phenomena but complementary inscriptions of cosmic light within living matter. One converts radiance into growth; the other converts radiance into endurance. Both are forms of intelligence—one outwardly creative, the other inwardly preservative—united in the higher coherence of life. Through them, the cosmos continues its eternal experiment: learning to live with its own luminosity, balancing the forces of cohesion and decohesion through the delicate architectures of the cell.

Both chloroplasts and melanoblasts mediate light–matter interactions, but they do so from opposite sides of the cosmic dialectic: Chloroplasts internalize light, creating structure from energy—a process of cohesive assimilation. Melanoblasts, through melanin, externalize and modulate light, protecting structure from excessive energy—a process of decohesive stabilization. Thus, they are antiphonal processes in the biosphere’s photonic symphony. The chloroplast transforms light into life; the melanoblast ensures that life is not dissolved by light. The two together form a dialectical circuit of photonic regulation—a balance between creative absorption and protective dissipation.

From an evolutionary standpoint, one might say that plants embody the positive metabolism of light, while animals embody the negative metabolism of light—one integrating photons into structure, the other integrating their absence into order. Both modes are indispensable: without the plant’s cohesive synthesis, there would be no biospheric energy base; without the animal’s decohesive modulation, there would be no stable complexity capable of perception and mobility.

In the deepest sense, both chloroplasts and melanoblasts represent two dialectical phases of the same cosmic process—the universe learning to handle its own radiant energy within the domain of life. Chloroplasts show how light can be materialized into biochemical coherence; melanoblasts show how that same light can be transmuted into stability and self-protection. Both are manifestations of the universal intelligence of matter, which seeks equilibrium through opposing pathways of transformation.

If chloroplasts may be viewed as the eyes of the plant, seeing light by absorbing it into being, then melanoblasts are the skin of the animal, feeling light by resisting its intrusion. Each transforms the photonic field into an expression of awareness: one as synthesis, the other as defense; one as creation, the other as preservation.

Chloroplasts and melanoblasts symbolize the two poles of the “photonic dialectic”—the living synthesis of cohesion and decohesion at the cellular level. Through them, the universe performs its most intimate act: converting light into life, and protecting life from light. In their harmony, the cosmos achieves biological coherence, showing that evolution is not a blind process but a dialectical unfolding of the intelligence of matter itself.

The evolution of life from its simplest molecular beginnings to the emergence of consciousness represents one of the most profound trajectories in the history of the cosmos. In the light of Quantum Dialectics, this transformation is not an accidental series of biochemical accidents but the necessary self-unfolding of the universal dialectic of cohesion and decohesion. The same forces that govern atomic bonding and stellar fusion reappear, in higher order, as the forces of integration and differentiation that organize living systems.

The rise of neurons, nervous systems, brains, and consciousness marks the neuralization of matter—the moment when the universe begins to internalize its own processes of interaction, feedback, and reflection. Just as plants embody the cohesive pole of life, synthesizing energy from light and integrating it into stable order, animals embody the decohesive pole, mobilizing that stored energy into motion, sensation, and action. Out of this polarity arose a new synthesis—conscious awareness—through which matter began to perceive, represent, and transform itself.

At the earliest stages of biological evolution, life operated through chemical and electrical gradients that mediated energy flow and information exchange within and between cells. Even the simplest prokaryotes demonstrated proto-neural behavior: they sensed chemical concentrations, adjusted motility, and communicated through signaling molecules—an embryonic form of cognition. This primitive sensing marks the first dialectical inflection point in the history of life: the shift from passive reaction to active relation.

The emergence of neurons was an evolutionary response to the dialectical contradiction between speed and stability. Chemical diffusion, though reliable, was too slow for organisms that moved through changing environments. To resolve this tension, evolution developed the electrical cell—the neuron—which could transmit information across distance at the speed of ion flow while maintaining chemical specificity.

A neuron, therefore, is not merely a specialized cell but a dialectical synthesis of chemistry and electricity—a living structure where cohesive metabolic continuity meets decohesive electrodynamic flux. It is the first cell that truly “thinks” in time, transforming spatially distributed information into temporal coordination. In this act, matter became capable of instantaneous reflection, and life entered the domain of self-regulating awareness.

With the evolution of multicellularity, the need arose for systems that could integrate the activities of diverse cells into coherent behavior. The earliest nerve nets in jellyfish and hydra provided distributed coordination—a network without hierarchy, where information flowed in all directions. This stage still mirrored the plant-like cohesion of distributed intelligence, but within an animal body capable of motion.

As evolutionary complexity increased, directional movement demanded centralization—the gathering of sensory information into specialized ganglia and later brains. This centralization did not abolish the distributed nature of intelligence but sublated it into a higher order: unity through hierarchy, coherence through differentiation. The nervous system thus represents the return of cohesion within decohesion—a moving structure that preserves inner order while engaging the outer flux.

In its architecture, the nervous system reflects the universal dialectical code: Peripheral nerves embody decohesion—reaching outward, diversifying, sensing. Central structures embody cohesion—integrating, stabilizing, synthesizing. Their dynamic communication forms the living negation of separation—a continuous oscillation between expansion and integration that mirrors the movement of the cosmos itself.

The brain represents the culmination of this evolutionary dialectic. It is not a machine of computation but a self-organizing field of dynamic coherence, where trillions of neurons oscillate in complex synchronization, maintaining order within constant flux. In physical terms, the brain sustains itself near the edge of chaos, balancing stability and instability in the same way the universe maintains equilibrium through dynamic tension.

Each neural impulse is a quantum dialectical event—a localized fluctuation in membrane potential that both unifies and differentiates, preserving the organism’s internal coherence while adapting to change. The electrochemical oscillations of neural networks embody the microcosmic rhythm of cohesion and decohesion: excitation and inhibition, integration and dispersion, signal and noise. Conscious experience emerges not from individual neurons, but from the global coherence achieved by their synchronized contradictions.

Thus, the brain can be viewed as matter’s most advanced form of dialectical organization—a system that perpetually reconstructs itself through contradiction, achieving self-awareness by internalizing the very structure of becoming.

From a quantum dialectical standpoint, consciousness is the emergent coherence of decoherent processes. It is the moment when energy, organized as neural dynamics, becomes capable of self-referential integration—the reflection of the system upon its own activity.

At every instant, countless neural signals compete, interfere, and cancel, yet out of this turbulence arises a stable, unified field of awareness. This mirrors the behavior of quantum systems, where superposed states collapse into coherent order through relational entanglement. The brain, in this sense, functions as a macro-quantum organism: a living superposition that constantly collapses into the actuality of perception, thought, and will.

Consciousness, therefore, is not a static “thing” but a dialectical movement of coherence across multiple quantum layers—molecular, cellular, neural, and social. It arises wherever contradictions are internalized and resolved through recursive reflection. Every act of awareness is a moment of dialectical synthesis, in which the universe briefly recognizes itself through the self-cohering dance of its own energies.

To understand the uniqueness of neural consciousness, one must revisit its complementary absence in plants. Plants, lacking neurons, possess a form of awareness that is distributed, spatial, and cohesive. Their communication occurs through bioelectrical waves, chemical messengers, and photoreceptive gradients. They perceive and respond to light, gravity, and touch, yet their responses are not centralized or instantaneous; they are holistic and field-like. The plant’s consciousness is the consciousness of being—it knows by integration, by becoming one with the environment it senses.

Animals, by contrast, embody the consciousness of becoming. Their nervous systems fragment and recombine perception through time, allowing for anticipation, memory, and directed movement. They must constantly resolve the tension between inner stability and external change. Hence, while the plant synthesizes light into life, the animal translates that life back into experience and motion.

The nervous system thus marks the decohesive leap of perception—the externalization of awareness into time, the conversion of environmental flux into internal representation. In this transformation, consciousness becomes not a passive reflection but an active process of reconstruction, through which life continuously interprets and reshapes its world.

The human brain represents the culmination of the dialectical ascent of matter toward self-reflection. It is the site where the cohesive memory of the plant, the reactive intelligence of the animal, and the reflective abstraction of consciousness converge. In its layered anatomy—the reptilian brain of instinct, the mammalian brain of emotion, and the neocortex of thought—we see the history of life condensed into structure, each layer preserving and transcending the contradictions of the previous.

Through language, symbolic thought, and moral reasoning, the human mind transforms biological awareness into cosmic self-consciousness. It is here that the universe, through its own evolution, achieves the ability to contemplate its origins and direct its future. The neuronal coherence patterns of human thought are the brain’s internal photosynthesis—the conversion of informational light into conceptual energy. Every idea is a photon transformed into meaning; every act of imagination is the cosmos thinking itself through the medium of the nervous system.

In this sense, the human brain is not merely an organ of survival but a dialectical organ of reflection—a microcosmic mirror of the universe’s evolutionary logic. Its cohesive forces (reason, memory, structure) and decohesive forces (desire, creativity, novelty) constantly interact to generate intelligent equilibrium, the capacity for freedom and understanding.

The evolution of the nervous system is not complete. Humanity, as the biosphere’s reflective mediator, now extends the neural principle into the technological domain, constructing global networks that mimic and amplify the integrative functions of the brain. The internet and artificial intelligence are the planet’s emergent nervous system, the externalization of cognition into planetary circuitry.

From the standpoint of Quantum Dialectics, this is not a deviation but the next negation in the evolutionary dialectic—the transition from biological to planetary coherence. Just as neurons arose to coordinate multicellular organisms, humanity’s neural technologies may evolve to coordinate the entire Earth system into a higher level of reflective unity: a conscious biosphere.

In this unfolding synthesis, consciousness continues its cosmic trajectory—from molecules to minds, from neurons to networks—each new phase preserving and transcending the contradictions of the previous one.

The evolution of neurons, nervous systems, brains, and consciousness represents the dialectical culmination of the universe’s drive toward self-organization and self-recognition. From the cohesive intelligence of plants to the decohesive intelligence of animals, and from the sensory integration of early neural networks to the reflective awareness of the human mind, the same universal logic unfolds: the tension between stability and transformation gives rise to higher coherence.

Consciousness is not a mystery outside of matter—it is matter’s highest mode of coherence, the state in which the universe becomes aware of its own becoming. The human brain, in its oscillating fields of light and thought, stands as the cosmos contemplating its own dialectical reflection—the living synthesis of cohesion and decohesion, being and becoming, order and creativity.

Through us, the universe knows. Through our awareness, it remembers. And through our future evolution—biological, social, and technological—it may yet learn to understand itself fully, transforming existence into a self-conscious harmony of energy, life, and mind.
