10. Immanence in Science and Cosmology: The Rejection of Transcendence From the earliest philosophical inquiries to modern cosmology, a recurring theme emerges: the universe can be understood and explained through principles residing within it rather than decrees imposed from beyond. While many Western religious traditions posit a transcendent Creator, numerous thinkers — ancient philosophers, modern scientists, and intermediaries like the Stoics — have gravitated toward a view that is more immanent. In such frameworks, divinity, rationality, and ultimate meaning are embedded in the cosmos, reflecting a shift away from anthropomorphic gods and external authorities, and toward intrinsic order and self-regulating processes. 10.1 The Milesian Revolution: Rooting Explanation in Nature In 6th-century BCE Ionia, the Milesian philosophers — Thales, Anaximander, and Anaximenes — rejected mythical explanations governed by gods who intervened arbitrarily in human affairs. Instead, they sought arche (origin-principles) within the cosmos itself (Graham 2006; Barnes 1982). Their approach replaced transcendent deities with natural forces and rational structures that could be observed, analyzed, and understood. Thales (c. 624–546 BCE): Identified water as the fundamental substance (arche). His claim that “all things are full of gods” did not invoke personified deities but suggested a universe pervaded by a divine rationality immanent in nature (Kahn 1960). Anaximenes (c. 586–526 BCE): Proposed air as the arche. Through processes of rarefaction and condensation, air transformed into all other forms — fire, wind, water, and earth — without requiring any external, supernatural agent (Barnes 1982). By grounding explanation in natural elements and processes, the Milesians established a precedent for understanding the universe as self-sustaining, dynamic, and orderly, prefiguring modern scientific inquiry. 10.2 Anaximander and the Apeiron: Infinite, Immanent Order Anaximander (c. 610–546 BCE) took the Milesian approach a step further by introducing the apeiron, a boundless, indefinite principle from which all things emerge and eventually return (Kirk, Raven & Schofield 1983). Unlike water or air, the apeiron had no specific material qualities, representing a universal source of balance and transformation. Immanent Divinity and Balance: The apeiron required no external deity to maintain order. Hot and cold, wet and dry, and all opposites find equilibrium within it. This internal cosmic justice (dike) arises naturally, not through divine fiat (Kirk et al. 1983). A Precursor to Pandeism: Anaximander’s apeiron embodied a divine rationality inherent in the cosmos, echoing what later would be recognized as a pandeistic perspective, where the divine is identical with the universe’s creative and sustaining forces (Deutsch 1969; Hadot 1998). 10.3 Pandeism and the Milesian Worldview The Milesians’ immanent cosmology laid intellectual groundwork that resonates with pandeism, the idea that the divine and the universe are one. Rather than gods imposing order from above, the divine is manifest in the inherent rationality and generative power of the cosmos itself. This holistic vision, free of transcendent intervention, integrates seamlessly with the interconnected outlook emphasized throughout this article — encompassing theology, ecology, psychology, politics, ethics, and epistemology. By rooting meaning and morality in the natural order, knowledge and virtue become accessible through observation, reason, and participation in the cosmic web rather than dependence on external revelations. 10.4 Decentralizing Knowledge: Observation Over Revelation The Milesians’ emphasis on natural explanations democratized knowledge. Truth no longer belonged exclusively to those claiming divine intermediaries; it became available to anyone capable of rational observation and analysis. This intellectual decentralization mirrored evolving political structures in Greek city-states, which began to embrace more participatory forms of governance (Loy 1988; Pelikan 1971). Such an approach anticipated the scientific method’s reliance on empirical evidence. By freeing knowledge from the chains of dogma, the Milesians paved the way for science to become a self-correcting, open-ended pursuit — an endeavor that thrives on questioning, testing, and refining ideas, much like immanent spiritual frameworks thrive on inner coherence and adaptability. 10.5 The Apeiron and Contemporary Science Although separated by millennia, Anaximander’s apeiron finds conceptual kinship in modern physics. Contemporary science describes reality through fields, forces, and emergent patterns — concepts that, like the apeiron, suggest a cosmos governed by intrinsic principles of order and change (Rovelli 2018; Capra 1996). The natural laws uncovered by physics, chemistry, and biology reveal a universe that requires no external lawgiver, aligning with the Milesian legacy of intrinsic rationality. 10.6 From Stoicism to Spinoza The notion that the divine might be immanent and accessible through rational understanding of the universe has deep historical roots in philosophical and religious traditions preceding modern science. The Stoics (3rd century BCE onwards) viewed the cosmos as permeated by logos (rational order), an early prototype of immanent theology that would later influence thinkers inclined toward rational inquiry (Long & Sedley 1987). In the 17th century, Baruch Spinoza developed a pantheistic philosophy, identifying God with Nature itself (Deus sive Natura), thereby rejecting the idea of a separate divine artificer (Deutsch 1969). Such philosophical currents provided fertile ground for later scientists to conceive of the cosmos as rational and self-organizing, integrating the sacred and the material. This shift from an externalized, commanding deity to an intrinsic order, knowable through reason, set the stage for modern scientists to find spiritual significance in the pursuit of knowledge rather than obedience to divine commands. 10.7 Einstein’s Non-Anthropomorphic Divinity and Cosmic Awe Albert Einstein’s views are among the most prominent examples of a scientist gravitating toward an immanent concept of God. While publicly dismissive of a personal, anthropomorphic deity — calling such notions “childlike” — Einstein held a profound reverence for the orderly structure of the universe. He claimed not to be an atheist but also resisted the pantheist label as too narrow, suggesting instead that the “problem is too vast for our limited minds” (Einstein 1954a). Einstein admired Spinoza’s God, an impersonal, all-encompassing principle manifest in the laws of nature (Einstein 1947). Rather than praying to a creator external to existence, he envisioned God as the mysterious order underlying all phenomena. He compared humanity’s intellectual efforts to a child in a grand library, aware that someone must have written the “books” but unable to comprehend the “languages” or the authors. Here, God is not a transcendent architect but the rational structure dimly perceived by human minds. Einstein’s stance exemplifies how scientific engagement with reality can lead to a “religious feeling of a special sort,” rooted in wonder and rational admiration rather than transcendent worship (Einstein 1954b). 10.8 Carl Sagan’s Cosmic Immanence and Ethical Implications Carl Sagan, a 20th-century astrophysicist and science communicator, carried Einstein’s torch forward into an era of heightened environmental awareness and cosmic exploration. Rejecting any notion of a God outside the universe, Sagan emphasized the sacredness of the cosmos itself (Sagan 1980; Sagan 1994). For Sagan, the universe — ancient, vast, and self-organizing — constituted a source of awe and meaning that did not depend on supernatural intervention. By framing humanity as “star-stuff,” Sagan underscored the immanent connectedness of all life with cosmic processes. This perspective naturally engenders ethical responsibility: realizing our cosmic origins and the delicate balance of planetary ecosystems prompts a moral imperative to care for each other and the environment. Sagan’s approach aligns with Stoic and Taoist principles, where virtuous action and wise living arise from recognizing one’s place in an interdependent cosmos (Hadot 1998; Loy 1988). 10.9 Other Influential Figures and Movements While Einstein and Sagan stand at the forefront, they were not alone in gravitating toward an immanent spirituality. Physicists like Niels Bohr and Erwin Schrödinger, influenced by Eastern philosophies, sometimes implied a unity of knower and known that dissolves the dualism between humanity and a transcendent creator. Schrödinger’s engagement with Vedānta, for instance, showed a sympathy toward non-dualism, where Atman and Brahman are one, resonating with immanent religious thinking (Deutsch 1969). James Lovelock’s Gaia hypothesis, though not explicitly theological, presents Earth as a self-regulating system. This ecological model can be read as resonating with immanent religious perspectives that view nature as infused with an organizing principle (Capra 1996). Such scientific concepts, while remaining strictly empirical, open doorways to spiritual interpretations that celebrate interconnectedness and the reverence due to life’s complexity. 10.10 The Natural Syntony of Science — Especially Cosmology — with Immanence Modern cosmology, which studies the universe’s origins, structure, and evolution, inherently pushes human thought toward concepts that resemble immanent theology. As the Hubble Space Telescope and other observational technologies reveal a cosmos teeming with galaxies and dark matter, guided by gravitational laws and physical constants, it becomes increasingly plausible to frame these principles as intrinsic to reality rather than imposed from without. From the Big Bang to cosmic inflation, science paints a picture of a universe whose properties emerge from within, governed by laws that scientists strive to understand. Such inquiry does not require a transcendent being acting as a first cause; instead, it often suggests a principle of self-organization, complexity, and rationality inherent in the universe’s very fabric. This viewpoint mirrors the immanent stance: the divine or ultimate reality is not an external presence but is embedded in the cosmic tapestry itself. 10.11 Immanence Versus Transcendence: Revisited in Light of Science Transcendental theology posits an external Creator who fashioned the universe from nothing and remains fundamentally distinct from it (Pelikan 1971). Immanent theologies, by contrast, consider the universe eternal or self-organizing, rendering the divine an internal principle rather than an external agent. In transcendental frameworks, morality and meaning are often dictated by top-down authority; immanent frameworks see ethics and purpose as emerging from understanding and aligning with the cosmos’s inherent order (Loy 1988; Long & Sedley 1987). As Einstein’s rejection of anthropomorphic deities and Sagan’s cosmic reverence show, scientists often find transcendental assumptions unnecessary or restrictive. Instead of obedience to external commands, these thinkers cultivate an ethos grounded in curiosity, humility, and ecological responsibility. As humanity grapples with climate change, resource scarcity, and global tensions, the integrative ethic of immanent spirituality — where meaning and morality arise from recognizing our place in a vast, coherent universe — offers guidance sorely needed in contemporary times. 10.12 A Convergence of Tradition and Innovation The modern scientists’ turn toward immanence can be seen as both a revival and a reinvention of ancient wisdom. Philosophical traditions like Stoicism, Taoism, and Advaita Vedānta long emphasized the divine as immanent, perceiving unity beneath apparent multiplicity (Deutsch 1969; Loy 1988). Today’s physicists, with unprecedented tools and theories, rediscover a cosmos that, while described in the language of mathematics and empirical testing, can still inspire wonder and a quasi-spiritual reverence akin to immanent religiosity. Carl Sagan’s call to see the Earth as “a single organism” and Einstein’s insistence that even the most brilliant minds cannot fully comprehend the “mysterious force” directing the constellations (Einstein 1930) together outline a landscape in which science, in its purest form, resonates with immanent religious ideas. The “God” that Planck mentioned as the “goal of every thought process” in science need not be a transcendent figure; it can be the rational structure of the universe, the cosmic order that scientists continuously strive to understand (Planck 1931). 10.13 Science as a Pathway to Immanent Spirituality Over centuries, scientists and physicists have gravitated toward perspectives that can be interpreted as favoring immanent religion. This tendency is not accidental. Scientific inquiry, especially in cosmology, naturally reveals a universe governed by principles that emerge from within rather than decrees handed down from beyond. This vision aligns with immanent theological models, which see the divine as inseparable from the cosmos. Einstein’s reverence for Spinoza’s God and Sagan’s cosmic piety exemplify how scientific minds find spiritual depth in understanding, not obedience; in the cosmos’ inherent order rather than an external Creator’s pronouncements. Together, they and others have shown that the boundary between rational inquiry and spiritual insight can be porous. Immanent religiosity becomes a bridge between knowledge and meaning, drawing from ancient philosophical traditions and fulfilling modern ethical and existential needs. As we look to the future, where scientific discovery will only deepen and our understanding of the universe broaden, the natural compatibility of science with immanent spirituality may become even more apparent. In this synergy lies a hopeful vision: that by understanding the laws of nature, we can also discover principles to guide ethical action and compassionate stewardship, forging a spirituality that is both grounded in reality and ennobling to the human spirit. Carl Sagan, the celebrated astrophysicist, cosmologist, and science communicator, consistently expressed a profound reverence for the universe. His works, particularly Cosmos (1980) and Pale Blue Dot (1994), reveal a vision that resonates deeply with the principles of immanent theology. Sagan’s arguments for an immanent understanding of the divine — while avoiding overt religious language — emphasize unity, interconnectedness, and the self-organizing nature of existence. This appendix explores Sagan’s implicit call for an immanent spirituality, examines his main arguments, addresses potential critiques, and evaluates the merits of his perspective in contemporary contexts. Sagan described the cosmos as a “profoundly beautiful” and awe-inspiring entity, urging humanity to find meaning and transcendence within the natural order itself. He saw no need for a divine Creator separate from the universe; instead, he believed that the universe itself embodies qualities worthy of reverence. “The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.” — Cosmos This statement encapsulates Sagan’s immanent view: humans are not apart from the universe but intrinsic participants in its unfolding story. This perspective aligns with the Stoic concept of logos, the Taoist understanding of the Tao, and the Advaita Vedānta notion of Brahman — all of which view the divine as inherent within the cosmos and accessible through direct experience and understanding. Emphasizing the interconnected nature of all life and matter — a hallmark of immanent theology — Sagan viewed humanity as part of a vast cosmic web, bound by the same physical and biological laws that govern the universe. “The surface of the Earth is the shore of the cosmic ocean. On this shore, we’ve learned most of what we know. Recently, we’ve waded a little way out, maybe ankle-deep, and the water seems inviting.” — Cosmos This metaphor suggests that exploration and understanding of the cosmos — not external worship — are pathways to meaning and spiritual fulfillment. It reflects the immanent theological principle that the divine or ultimate reality is intimately woven into the fabric of the universe, inviting us to engage with it directly. Sagan was critical of transcendental theological models that posited a deity separate from the universe. He viewed such beliefs as unnecessary and often detrimental to scientific inquiry and ethical progress. “If by God one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying… it does not make much sense to pray to the law of gravity.” — Conversations with Carl Sagan By rejecting supernaturalism, Sagan aligns with immanent perspectives where reverence is directed toward the cosmos itself, not an external deity. His emphasis on understanding and appreciating the universe as it is parallels the immanent focus on direct experience and internal alignment with the rational order of existence. Sagan’s Main Arguments for an Immanent Spirituality Sagan argued that the universe’s vastness and complexity provide a sufficient source of awe, inspiration, and ethical grounding. By understanding our place in the cosmos, we can develop a profound sense of belonging and purpose. The iconic Pale Blue Dot photograph, showing Earth as a tiny speck in the vastness of space, was used by Sagan to inspire humility and a recognition of our shared humanity. “Look again at that dot. That’s here. That’s home. That’s us… To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.” — Pale Blue Dot This perspective encourages an immanent spirituality that finds meaning within the interconnectedness of all things, emphasizing that our significance arises from our participation in the cosmos. Sagan believed that curiosity and the pursuit of knowledge are inherently spiritual activities. He called for a reverence for the scientific process as a means of uncovering the underlying principles of the universe. “Science is not only compatible with spirituality; it is a profound source of spirituality.” — The Demon-Haunted World This view reflects the immanent theological emphasis on direct engagement with reality as a path to understanding the divine. By advocating for evidence-based inquiry and openness to revision, Sagan promotes a spirituality grounded in exploration and continual growth. Recognizing the interconnectedness of all life fosters ethical responsibility in Sagan’s view. Understanding our shared origins and common destiny in the cosmos can inspire compassion, ecological stewardship, and efforts to prevent conflict. “A new consciousness is developing which sees the Earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet.” — Cosmos This ethical universalism aligns with immanent theological principles that emphasize the unity of existence and the moral imperative to act in ways that support the well-being of the whole. Some critics argue that Sagan’s cosmic vision lacks the personal and emotional dimensions of traditional religions, such as a personal relationship with a deity or the comfort provided by religious rituals and communities. They suggest that his perspective might not fulfill the human desire for relational intimacy and emotional support. However, Sagan’s emphasis on interconnectedness offers a relational depth that transcends anthropocentric limitations. By viewing humanity as an integral part of the cosmos, he provides a sense of belonging and purpose that can satisfy the yearning for connection. The awe and wonder inspired by the cosmos can evoke profound emotional responses, fostering a spirituality that is both intellectually and emotionally fulfilling. Moreover, his approach does not preclude the formation of communities or shared rituals; instead, it invites the creation of new forms of communal engagement centered around the exploration and appreciation of the universe. Planetariums, science festivals, and environmental movements often serve as modern congregations where people gather to celebrate and learn about the cosmos, fostering a sense of community and shared purpose. Sagan’s vision aligns seamlessly with contemporary scientific discoveries in cosmology, ecology, and systems theory, which reveal the universe as a self-organizing, interconnected system. His emphasis on immanence reflects the Stoic understanding of logos and modern insights into emergent order in natural systems. By integrating scientific knowledge with a sense of reverence, Sagan bridges the gap between empirical understanding and spiritual experience. This approach validates the emotional and ethical significance of scientific exploration, encouraging a worldview that harmonizes reason and wonder. By emphasizing our shared origins in “star-stuff” and the fragility of Earth, Sagan’s immanent approach fosters a sense of global responsibility. His call for ecological consciousness and mutual respect transcends cultural and religious boundaries, encouraging collaborative efforts to address global challenges such as climate change, biodiversity loss, and socio-economic inequality. Recognizing that all humans share the same cosmic heritage can inspire solidarity and compassion, reducing divisions based on nationality, race, or creed. This ethical universalism is vital in an interconnected world where collective action is necessary to solve complex problems. Sagan’s ability to convey the majesty of the cosmos inspires a sense of awe akin to religious reverence. This emotional resonance makes his perspective accessible and transformative, offering a spiritual alternative grounded in reality. The Pale Blue Dot photograph, for example, catalyzed public awareness of Earth’s fragility, inspiring environmental movements and initiatives like Earth Day and international climate agreements. Sagan’s narratives encourage individuals to engage with the universe emotionally and intellectually, fostering a lifelong commitment to learning and exploration. Sagan’s emphasis on planetary stewardship aligns with global sustainability goals, urging humanity to act as caretakers of Earth. His vision has inspired environmental activism, emphasizing the importance of preserving our planet for future generations. Movements such as the Paris Climate Agreement reflect the global consciousness Sagan advocated, recognizing that protecting our shared home requires international cooperation and a sense of collective responsibility. The call to find meaning within the cosmos echoes in contemporary mindfulness practices, which encourage presence, interconnectedness, and appreciation of the present moment. By fostering awareness of our place in the universe, individuals can cultivate inner peace and a deeper connection to the world around them. Mindfulness-based stress reduction programs and the increasing popularity of meditation reflect a societal shift toward practices that resonate with immanent spirituality, emphasizing internal alignment and holistic well-being. Sagan advocated for responsible exploration of space, emphasizing that our ventures into the cosmos should be conducted with humility and respect for potential extraterrestrial life and ecosystems. This perspective reflects an immanent ethic that values all forms of existence. Discussions around planetary protection policies and the ethical implications of colonizing other planets are informed by the principles Sagan championed, highlighting the need for ethical frameworks that extend beyond Earth. In an era defined by environmental degradation and social fragmentation, Carl Sagan’s implicit call for an immanent spirituality offers both a grounding force and a call to action. By rooting meaning and reverence in the cosmos itself, he provides a framework for spirituality compatible with scientific inquiry and ethical progress. Sagan’s vision of humanity as conscious participants in a self-organizing, interconnected universe aligns with the principles of immanent theology found in Stoicism, Taoism, and other traditions. His insistence that “we are a way for the universe to know itself” reflects the immanent theology that views human consciousness as an integral expression of universal rationality. By embracing our role within the cosmos and finding transcendence within it, we can foster a more compassionate, unified, and sustainable future. Sagan’s work challenges us to develop a “new consciousness” grounded in the unity of life, inspiring practical actions such as environmental stewardship, cross-cultural collaboration, and the pursuit of knowledge. Refuting Transcendental Phsyics Laws of nature are not eternal, transcendent entities waiting to be discovered, but rather emergent patterns inseparable from the actual material and energetic configurations of the cosmos. The rational order of the cosmos is not an external blueprint but as arising from and expressed within the fabric of reality itself. There is no such a thing as a “separate realm”, and not evidence at all of it either (fantastic claims are not evidence). The notion of disembodied, eternal laws floating in a metaphysical ether contradicts the principle that meaning and order must be grounded in actual, material phenomena (Hadot 1998; Lloyd 1978). Laws do not “exist” beyond the universe but are conceptual tools humans derive by observing stable patterns. Without matter-energy configurations, no pattern can arise, and thus no “law” can even be formulated. Imagining a law like conservation of energy “existing” in a universe empty of matter and energy is tantamount to positing patterns without anything to pattern. Instead, laws are descriptive constructs that emerge from observing material interactions (Capra 1996). Without matter or energy, no process or interaction can occur, and thus no pattern can be identified. “Laws” that supposedly remain “waiting” in void are human abstractions mistakenly reified as independent entities. Newton’s gravitational law is not a metaphysical “entity” but a descriptive model summarizing observed relationships between masses. Without masses, the concept of gravitational attraction is empty. From an immanent lens, laws arise from and are meaningful only within contexts where their conditions are met. They do not “define relationships” in a vacuum; rather, they capture regularities we extrapolate from actual gravitational interactions. Without actual gravitational phenomena, speaking of a gravitational law “existing” is as nonsensical as discussing the flight patterns of birds in a universe without birds. Immanent approaches tie the existence of any such regularity to material instantiation (Maturana & Varela 1980; Kauffman 1995). Refuting the View of Laws as Discovered Abstract Truths Furthermore, scientists do not uncover pre-existing laws hidden in a metaphysical realm; rather, they formulate conceptual frameworks that approximate observed patterns in nature (Long & Sedley 1987). We invent models that fit the empirical data, and these models remain valid only insofar as they correlate with observable phenomena. Rationality and purpose arise from within the universe’s dynamic processes. Laws are emergent properties or conceptual instruments rather than eternal facts waiting for discovery (Lloyd 1978; Hadot 1998). Order, rationality, and meaning are integrally part of the universe’s actual processes. By locating significance within the cosmos rather than beyond it, immanent models circumvent the philosophical problems posed by transcendental arguments. Instead of positing disembodied laws that govern a hypothetical void, immanence grounds patterns in matter-energy configurations themselves. The cosmos is not a machine operated by external instructions; it is a living, self-sustaining whole, from which intelligible patterns (what we call “laws”) emerge. This approach better reflects contemporary understandings of complexity and self-organization, where stable patterns result from interactions, feedback loops, and the inherent properties of systems (Kauffman 1995; Capra 1996). By acknowledging that laws arise from and depend on phenomena, immanence aligns philosophy with empirical evidence, dispensing with unnecessary metaphysical realms that transcend observable reality. In other words, transcendent models ask us to accept metaphysical blueprints existing in a disembodied realm, while immanent perspectives show that it is the cosmos’ tangible reality that gives rise to structure, order, and meaning. Laws, therefore, are not discovered cosmic blueprints, but conceptual frameworks we create to describe the self-organizing rationality inherent in nature. “If man has learned to see and know what really is, he will act in accordance with truth, Epistemology is in itself ethics, and ethics is epistemology.” — Herbert Marcuse Epistemology, the study of knowledge, examines what knowledge is, how we acquire it, how we differentiate truth from belief, and how we reconcile the limitations of the human mind with the complexity of the world. Grasping epistemology is crucial because it shapes our interpretation of reality and guides our pursuit of truth. Throughout Western philosophy, two dominant frameworks have offered contrasting perspectives on these issues: the Kantian-Cartesian epistemology, influenced by Platonic idealism and aspects of the Judeo-Christian tradition, and Stoic epistemology, grounded in direct engagement with reality. These frameworks provide radically different answers regarding the nature of knowledge and its relationship to the knower. Kantian and Cartesian thought emphasize dualisms — such as subject and object, phenomenon and noumenon, mind and body. In this view, knowledge is mediated through mental structures that shape experience but simultaneously distance the knower from reality itself. The external world is perceived as something to be ordered by higher principles: the mind’s a priori categories in Kant’s philosophy or transcendent Forms in Plato’s thought¹-². Reality, within this framework, lacks intrinsic order or autonomy; it becomes intelligible only through external structuring mechanisms imposed by the mind. In contrast, Stoic epistemology rejects these dualisms, emphasizing immanence over transcendence and realism over idealism. The Stoics propose a cosmos inherently imbued with logos — a rational, self-organizing principle that permeates all things³. Knowledge arises not from imposing order on a passive external world but from actively participating in the intrinsic order of reality. Entities possess their own internal causes and roles within the larger rational system, rather than being mere recipients of external forces⁴. This fundamental difference — between imposing order and participating in inherent order — highlights a key philosophical divide. Kantian and Cartesian epistemologies view the mind as a transcendent agent imposing structure on an otherwise chaotic or inaccessible reality⁵-⁶. Stoic epistemology, by contrast, sees humans as integral parts of a rational whole, where perception and reason are expressions of the cosmos’s immanent order⁷. This perspective dissolves the gap between subject and object, theory and reality, positioning knowledge as a direct engagement with truth. The limitations of the Kantian-Cartesian framework have become increasingly apparent, particularly concerning unresolved issues like the mind-body problem and the inaccessibility of the noumenon⁸-⁹. Advances in modern science — such as discoveries in neuroscience, systems theory, and embodied cognition — highlight the relevance of Stoic ideas, especially their focus on unity, causation, and participation¹⁰-¹¹. This article proposes that revisiting Stoic epistemology, enriched by contemporary insights, can address the paradoxes inherent in dualistic traditions. By comparing these frameworks, we aim to demonstrate that Stoicism offers a more coherent and practical understanding of knowledge and reality. 2.1 Timeline Pre-Socratic and Classical Period (6th–4th centuries BCE) Philosophical Context: Immanence and Cosmic Unity 6th Century BCE: Heraclitus Introduces Logos Heraclitus proposes that logos is the rational principle governing the universe, emphasizing intrinsic order and unity. He asserts, “Listening not to me but to the logos, it is wise to agree that all things are one” (Heraclitus, Fragment 50) (Kirk, Raven & Schofield 1983). 5th Century BCE: The Flourishing of the Eleusinian Mysteries The Eleusinian Mysteries become prominent, offering initiates direct participation in nature’s cycles and personal transformation, symbolizing unity with the divine (Mylonas 1961). 4th Century BCE: Plato’s Theory of Forms Plato introduces transcendental elements through his Theory of Forms, positing a realm of immutable, perfect ideals. However, he maintains immanent aspects by emphasizing the soul’s pursuit of the Good within the material world (Plato, Republic 509b) (Plato 1997). Hellenistic Period (3rd–1st centuries BCE) The Stoic Era: Immanent Freedom Defined by Rational Participation 3rd Century BCE: Zeno of Citium Founds Stoicism Zeno establishes Stoicism, advocating living in accordance with logos. Stoic freedom is defined as rational self-determination, aligning one’s will with the cosmic order (Long & Sedley 1987). 2nd Century BCE: Development of Stoic Philosophy Chrysippus, a key Stoic philosopher, further develops Stoic logic and ethics, emphasizing the role of prohairesis (rational choice) in achieving virtue (Inwood & Gerson 2008). Late Hellenistic and Early Roman Period (1st century BCE–2nd century CE) The Rise of Transcendental Frameworks 1st Century CE: Increasing Influence of Judeo-Christian Thought Christianity begins to emerge, emphasizing a transcendent Creator God separate from the material world. The concept of freedom shifts toward obedience to divine will, introducing dualisms between Creator and creation (Markschies 2000). 1st–2nd Century CE: Epictetus and Stoic Ethics Epictetus, living in the 1st–2nd centuries CE, teaches the importance of focusing on what is within our control and aligning with logos. He reinforces the Stoic idea of freedom through rational assent (prohairesis) (Epictetus, Discourses I.1) (Epictetus 2008). Late Antiquity (3rd–5th centuries CE) The Decline of Immanent Traditions and the Institutionalization of Transcendence 3rd Century CE: Development of Neoplatonism Plotinus establishes Neoplatonism, blending Platonic idealism with mysticism. While emphasizing the transcendent One, Neoplatonism retains immanent aspects through the emanation of reality from the One (Plotinus, Enneads V.1) (Plotinus 1991). 4th Century CE: Christianity Becomes the State Religion Emperor Theodosius I declares Christianity the official religion of the Roman Empire. Pagan practices, including the Eleusinian Mysteries, are suppressed, symbolizing a cultural shift from immanence to transcendence (MacMullen 1984). 396 CE: Closure of the Eleusinian Mysteries The Eleusinian Mysteries are officially terminated, and the sanctuary at Eleusis is destroyed, marking the end of ancient immanent spiritual traditions (Miller 1997). Medieval Period (5th–15th centuries CE) The Dominance of Transcendental Thought 5th Century CE: Augustine of Hippo and Christian Doctrine Augustine articulates the Christian doctrine of original sin and divine grace, framing human freedom as dependent on God’s will. This reinforces the dualism between an omnipotent Creator and humanity (Augustine, Confessions) (Augustine 1991). 13th Century CE: Thomas Aquinas and Scholasticism Aquinas synthesizes Christian theology with Aristotelian philosophy, emphasizing divine revelation and the existence of a transcendent God. Scholasticism becomes the dominant intellectual tradition, prioritizing transcendence over immanence (Aquinas, Summa Theologica) (Aquinas 2006). 14th Century CE: Mysticism Challenges Transcendence Mystics like Meister Eckhart emphasize direct, unmediated experience of the divine, echoing immanent themes within a predominantly transcendental context (Eckhart, Sermons and Treatises) (Davies 1991). Early Modern Period (16th–18th centuries CE) The Rebirth of Rational Inquiry and Entrenchment of Dualism 17th Century CE: Descartes and Mind-Body Dualism René Descartes’ Cogito, ergo sum establishes a foundation for modern epistemology but entrenches dualism by separating the thinking mind (res cogitans) from the material body (res extensa) (Descartes 1641) (Descartes 1996). 18th Century CE: Kant’s Transcendental Idealism Immanuel Kant proposes that knowledge is mediated by the mind’s a priori categories, reinforcing the separation between subject and object and limiting direct knowledge of the noumenal world (Kant 1781/1787) (Kant 1998). Modern Period (19th Century CE–Present) Resurgence of Immanence in Philosophy and Science 19th Century CE: Nietzsche’s Critique of Transcendence Friedrich Nietzsche critiques the Judeo-Christian tradition, advocating for a revaluation of values grounded in life-affirming immanence and the concept of the Übermensch (Nietzsche, Thus Spoke Zarathustra) (Nietzsche 2006). 20th Century CE: Scientific Paradigm Shifts Einstein’s Theory of Relativity (1905–1915): Challenges Newtonian mechanics by demonstrating the interdependence of space, time, and matter, undermining absolute separations (Einstein 1916) (Einstein 2001). Quantum Mechanics: Reveals the fundamental interconnectedness and indeterminacy at the subatomic level, resonating with Stoic monism (Heisenberg 1958) (Heisenberg 2007). Systems Theory and Ecological Psychology: Emphasize holistic understanding and interdependence within complex systems, aligning with the Stoic view of a rational, interconnected cosmos (Capra 1996; Gibson 1979). 21st Century CE: Revival of Stoicism Renewed interest in Stoicism focuses on its practical ethics and philosophy, addressing modern concerns about resilience, mental well-being, and environmental interconnectedness (Pigliucci 2017; Robertson 2019). 2.2 From Inmanence to Transcendence The history of Western thought includes a significant transition from the immanent worldview of early philosophies, like Stoicism, to the transcendent metaphysics that gained prominence with the rise of Christianity and were later reflected in aspects of Platonic thought. Stoic philosophy emphasized immanence — the belief that the cosmos is rational, self-organizing, and intrinsically intelligible¹. In contrast, the Judeo-Christian tradition introduced a framework rooted in transcendence, where the ultimate source of order and truth lies beyond the material world². This shift reoriented metaphysical assumptions and epistemological frameworks, transforming conceptions of knowledge, freedom, and reality. It laid the groundwork for the dualisms that would later dominate Western philosophy, particularly in the Platonic, Cartesian, and Kantian traditions³-⁴-⁵. Understanding this historical evolution is essential for appreciating the epistemological divide between modern dualistic frameworks and the Stoic alternative, which emphasizes unity, direct engagement with reality, and participation in a rational cosmic order. At the core of Stoicism is the concept of logos, the rational principle that permeates and organizes the cosmos. For the Stoics, the universe is a single, self-determined system where all things are interconnected and governed by coherent order⁶. This worldview is characterized by: Immanence: The rational order of the cosmos is intrinsic to its nature, not imposed by an external agent. Every part of the cosmos, including human beings, participates in this rational structure⁷. Participation: Knowledge is not a mediated or abstract process but a direct alignment of human rationality with the universal logos. Perception (phantasia) is a form of active engagement, and truth is discerned through kataleptic impressions, which are clear and self-evident perceptions grounded in the rational coherence of reality⁸. Unity of Being: The Stoics rejected dualisms, viewing the cosmos as an integrated whole. Mind and body, subject and object, are different aspects of the same rational order⁹. In this framework, knowledge and freedom are intrinsically linked to the participatory model. To know the world is to harmonize with its rational structure, and to be free is to act in accordance with the cosmic order¹⁰. This immanent perspective places the human knower within the fabric of the cosmos, erasing the boundary between observer and observed. The rise of the Judeo-Christian tradition brought a fundamental reorientation of metaphysics, shifting from immanence to transcendence. Central to this worldview is the concept of a Creator God who exists outside of and above creation¹¹. This new metaphysical framework introduced a dualistic hierarchy: Transcendence: God, as the source of all order and truth, is wholly separate from the material world. The cosmos is no longer self-organizing but contingent upon the will of an external Creator¹². Idealization: Knowledge is conceived as an ascent toward divine truths that transcend the imperfections of the material world. The emphasis on eternal and immutable ideals contrasts with the Stoic focus on the dynamic rationality of the cosmos¹³. This metaphysical shift laid the foundation for the dualisms prominent in later philosophical traditions. While Plato’s philosophy predated Christianity, his theory of Forms introduced a level of transcendence that influenced subsequent thinkers¹⁴. However, it was the integration of Platonic thought with Christian theology that reinforced the dualistic separation between the material and the ideal, the human and the divine¹⁵. Understanding this historical context is crucial for appreciating how modern epistemological frameworks, such as those of Descartes and Kant, inherited and developed these dualistic tendencies. Descartes’ mind-body dualism and Kant’s distinction between phenomena and noumena reflect an ongoing struggle with the separation of the knower from the known, a challenge that Stoic epistemology seeks to overcome through its emphasis on immanence and participation¹⁶-¹⁷. 2.3 The Ethical Shift: From Internal Harmony to External Authority The shift from immanence to transcendence not only transformed metaphysical perspectives but also brought about a radical reconfiguration of ethical thought. In Stoicism, ethics is deeply rooted in the rational order of the cosmos (logos), where virtue is achieved by living in harmony with one’s rational nature and the rational structure of the universe (Long and Sedley 1987). In contrast, the Judeo-Christian tradition introduces an externalized ethical framework, grounded in divine commandments and mediated through religious authority (Augustine 1998). Stoic Ethical Immanence Living According to Logos: The Stoics conceive virtue as the alignment of human reason with the universal logos. Goodness is not dictated by external commands but discovered through rational inquiry and introspection (Epictetus 2008). This internal discovery emphasizes personal understanding and wisdom. Autonomy Through Reason: Acting virtuously involves exercising prohairesis, the rational faculty that allows individuals to make deliberate choices in accordance with the inherent rationality of the cosmos (Sellars 2006). This ethical model underscores self-determination, where moral choices reflect one’s participation in the rational order of being. Unity of Ethics and Ontology: For the Stoics, ethics is inseparable from their metaphysical understanding of the universe. The moral life emerges naturally from the intrinsic rationality of existence, as ethical behavior is an expression of living in accordance with nature (Marcus Aurelius 2006). Judeo-Christian Ethical Transcendence Obedience to Divine Commandments: In the Judeo-Christian framework, morality is defined by adherence to the will of a transcendent Creator-God. Ethical goodness becomes a matter of following divine laws, often communicated through sacred texts and religious leaders (Exodus 20:1–17; Aquinas 2002). The Role of Free Will: The concept of libertarian free will, differing from the causally determined freedom in Stoicism, frames moral responsibility as the capacity to choose between good and evil independently of antecedent causes (Augustine 1998). This emphasizes individual autonomy in moral decision-making. Dualism in Ethics: The separation between Creator and creation introduces a moral divide between the divine ideal and the imperfect material world. Ethical goodness is associated with transcending earthly imperfections and conforming to divine ideals (Plato 1997; Augustine 1998). 2.4 Physics: From Animated Systems to Inanimate Mechanics The metaphysical shift from immanence to transcendence influenced not only philosophy and ethics but also the evolving understanding of nature and physics. While Newtonian mechanics crystalized the mechanistic paradigm, the seeds of this approach were planted earlier, in the works of thinkers like Descartes and Galileo, who laid the groundwork for a physics that emphasized external causation and reductionism. This evolution marked a departure from earlier holistic and immanent conceptions, such as those found in Stoic physics. Stoic physics is grounded in the idea that the cosmos is a living, rational organism governed by logos. Every part of the universe, from stars to human beings, participates in this rational order (Chrysippus, as cited in Diogenes Laertius 1925). Self-Organizing Systems: The Stoics view the cosmos as a unified, self-determining whole, where all motion arises from the internal rationality of the system (Sambursky 1959). Dynamic Order: Change is not imposed externally but unfolds as a natural expression of the immanent logos. Every entity possesses an internal guiding principle that determines its behavior in harmony with the whole (Long and Sedley 1987). Holistic Integration: Nature is understood as an interconnected web of relationships, with no sharp division between the animate and inanimate. The Stoics see a continuum of being, unified by logos (Reydams-Schils 2010). The transition to mechanistic physics began during the Scientific Revolution, with thinkers like Descartes and Galileo emphasizing mathematical abstraction and external causation. Newton’s synthesis in the Principia Mathematica (1687) solidified this framework, replacing the immanent rationality of Stoic physics with a mechanistic model of nature. With the rise of Newtonian mechanics, the view of nature shifted dramatically. The cosmos was no longer seen as a living system but as a machine governed by mathematical laws and external forces (Newton 1999). Pre-Newtonian Mechanistic Foundations: Descartes (1596–1650): Descartes introduced the idea of nature as a machine, governed by mathematical laws and devoid of intrinsic purpose. He distinguished between res cogitans (thinking substance) and res extensa (extended substance), separating the mental from the physical and reducing the latter to mechanical processes. Galileo (1564–1642): Galileo’s emphasis on quantification and experimentation marked a shift toward understanding motion as governed by mathematical laws rather than inherent purposes, furthering the mechanistic paradigm. Newtonian Mechanics: External Forces: Newton formalized the mechanistic worldview by describing motion as the result of external forces acting upon inert matter. His three laws of motion and the law of universal gravitation provided a framework for understanding the cosmos as a system of interactions between discrete bodies (Newton 1999). Separation of Animate and Inanimate: Newtonian physics treated the universe as a collection of inanimate objects, with life and consciousness relegated to separate domains, thereby abandoning the Stoic view of a continuum of being. Reductionism: Nature was no longer seen as an integrated system but as a sum of its parts. The behavior of the whole was derived from analyzing isolated components, rather than understood as an integrated system, marking a departure from the holistic vision of Stoic physics (Capra 1996). However, recent developments in systems theory, complexity science, and quantum mechanics have begun to echo Stoic principles of immanent order. Self-Organizing Systems: The Stoic concept of logos finds a modern parallel in theories of self-organization, where complex systems — ranging from ecosystems to galaxies — emerge and maintain order without external direction (Prigogine and Stengers 1984). Dynamic Equilibrium: The Stoic emphasis on balance within the cosmos aligns with modern understandings of dynamic systems, which adapt and evolve while maintaining coherence (Capra 1996). Interconnectedness: Advances in ecological science and quantum physics reveal the interconnected nature of all things, resonating with the Stoic vision of a cosmos unified by rational principles (Bohm 1980). While the mechanistic paradigm brought remarkable progress in physics and technology, it also introduced a fragmented view of nature, separating the animate from the inanimate, and reducing the cosmos to a collection of isolated parts. The resurgence of holistic perspectives in modern science, inspired by theories of self-organization and interconnectedness, aligns with Stoic physics and its emphasis on immanent order. 2.5 Epistemological Implications This metaphysical shift profoundly affected conceptions of knowledge. External Authority: Knowledge of the world became dependent on divine revelation or theological interpretation, diminishing the role of direct human engagement with nature (Augustine 1998). Dualism: The separation of Creator and creation mirrored a broader epistemological divide between the ideal and the real, the knower and the known. The material world was often seen as flawed or opaque, requiring external mediation to access its truths (Plato 1997; Descartes 1984). The metaphysical and epistemological assumptions of the Judeo-Christian tradition laid the groundwork for the dualisms that would later dominate Western philosophy. Platonic Idealism: Plato’s theory of Forms, which predated Christianity but resonated with its transcendental focus, posited a higher realm of perfect, immutable ideals distinct from the imperfect material world (Plato 1997). This dualism between the ideal and the real was further entrenched in Christian metaphysics (Augustine 1998). Cartesian Dualism: René Descartes extended this separation to epistemology, introducing the subject/object divide. The thinking mind (res cogitans) became isolated from the material world (res extensa), with knowledge mediated through mental representations (Descartes 1984). Kantian Mediation: Immanuel Kant built on these dualisms by positing that all experience is structured by the mind’s a priori categories, leaving the “thing-in-itself” (noumenon) forever inaccessible. This framework perpetuated the idea that knowledge is mediated and distanced from reality (Kant 1998). In each of these traditions, the immanent unity of the Stoic cosmos gave way to a fragmented worldview where knowledge was no longer participatory but mediated, and reality was divided into irreconcilable realms. The transition from Stoicism to the Judeo-Christian ideal tradition represents a loss of the immanent perspective that defined ancient philosophy. Where the Stoics saw the cosmos as uncreated, self-determined, and inherently rational, the Judeo-Christian tradition introduced a dependence on external causation and transcendental ideals. This shift redefined: Knowledge: From direct participation in logos to a mediated ascent toward divine truths. Freedom: From alignment with the rational order of the cosmos to the libertarian free will of an immaterial soul, unbound by causality. Reality: From an integrated, self-organizing whole to a divided system of Creator and creation, ideal and real. Ethics: From internal harmony to external authority. This historical evolution created the epistemological conditions for the emergence of Platonic, Cartesian, and Kantian frameworks. It also set the stage for modern challenges of skepticism, dualism, and the alienation of the knower from the known.
