Hermes Trismegistus

About Hermes Trismegistus

Hermes Trismegistus — Hermes the Thrice-Great — is not a historical person in the ordinary sense but something far more interesting: a divine persona through which centuries of accumulated Egyptian, Greek, and Near Eastern wisdom found its voice. The name fuses two great gods of writing, magic, and mediation between worlds: the Egyptian Thoth (Djehuty), lord of sacred script, inventor of hieroglyphs, recorder of the weighing of hearts in the Hall of Ma'at, and master of the moon's cycles; and the Greek Hermes, the psychopomp who guides souls between realms, patron of boundaries and their crossing, god of communication, commerce, and the interpretive arts. The epithet 'Trismegistus' — thrice-great, or greatest of the great — appears first in Greek inscriptions at the temple of Thoth at Hermopolis (Khmun) in Egypt, where the local priesthood honored their god with the superlative form megistos kai megistos.

The writings attributed to Hermes Trismegistus — collectively known as the Corpus Hermeticum, the Emerald Tablet, and a vast body of technical and philosophical Hermetica — were composed over a period spanning roughly the first through fourth centuries CE, primarily in Greco-Roman Egypt, though some material may preserve genuinely older Egyptian temple teachings. These texts present themselves as dialogues in which Hermes instructs his son Tat, his student Asclepius, and the divine Nous (Mind) on the nature of God, the cosmos, the human soul, and the path to spiritual liberation through gnosis — direct experiential knowledge of the divine. For nearly two thousand years, these texts were believed to be the work of a single historical sage who lived before Moses and perhaps before the Pharaohs themselves — a belief that gave Hermetic wisdom the authority of the most ancient human knowledge.

The figure of Hermes Trismegistus cannot be understood apart from the cultural milieu that produced him: the extraordinary meeting of civilizations in Ptolemaic and Roman Egypt. When Alexander the Great conquered Egypt in 332 BCE, he set in motion a three-century experiment in cultural synthesis. Greek settlers, Egyptian priests, Jewish scholars, Persian magi, and Indian traders mingled in Alexandria, which became the intellectual capital of the ancient world. The great Library of Alexandria and the Mouseion (Museum) served as crucibles for this synthesis. Egyptian temple wisdom — traditionally restricted to initiated priests — began to be translated and transmitted in Greek, even as Greek philosophical categories reshaped the expression of Egyptian ideas. The Hermetic writings emerged from this matrix: they are neither purely Egyptian nor purely Greek but represent a genuine third thing, a new philosophical-spiritual tradition that drew on both while transcending either.

What makes Hermes Trismegistus unique among the founders (or mythical founders) of wisdom traditions is the extraordinary breadth attributed to his teaching. The Hermetic corpus addresses cosmogony (the creation of the universe through divine thought and the Word), anthropology (the nature of the human being as a divine-material hybrid capable of ascending to godhood or descending to bestiality), theology (the nature of God as both transcendent and immanent, both the All and the source of the All), psychology (the structure of the soul and its journey through the planetary spheres), ethics (the imperative to know oneself and thereby to know God), and practical arts including alchemy, astrology, talismanic magic, and medicine. This comprehensiveness — the vision of a unified wisdom encompassing both the theoretical and the practical, the spiritual and the material — is the hallmark of the Hermetic tradition and the source of its enduring appeal.

Contributions

The contributions attributed to Hermes Trismegistus span the entire range of human knowledge as understood in the ancient and medieval world. Because Hermes is a legendary rather than historical figure, 'his' contributions are really those of the Hermetic tradition as a whole — a tradition that developed over many centuries and profoundly shaped Western civilization.

The Philosophical Hermetica: A Vision of Cosmic Unity

The philosophical writings attributed to Hermes — primarily the seventeen tractates of the Corpus Hermeticum and the Latin Asclepius — present a remarkably coherent cosmology and soteriology (doctrine of salvation). The cosmos is created by the divine Mind (Nous) through the agency of the Word (Logos). The created universe is not evil (as in Gnostic systems) but is a beautiful image of God — 'a second god,' as the Asclepius calls it. The human being occupies a unique position in this cosmos: made in the image of the divine Demiurge, humanity alone among created beings possesses nous and the capacity for self-divinization. The famous passage in the Poimandres (Corpus Hermeticum I) describes how the Primal Man (Anthropos), gazing down through the cosmic spheres, falls in love with Nature and descends into material existence — but retains the capacity to ascend back through the seven planetary spheres, shedding each planet's influence, to return to the divine source. This cosmological drama became the template for countless subsequent Western esoteric systems of initiation and spiritual development.

The Hermetic concept of God is both radically transcendent and radically immanent. God is beyond all names and categories — 'without form and yet all-forming,' as Tractate V puts it — yet simultaneously present in all things: 'God is all that is, both the manifest and the unmanifest.' This paradoxical theology, sometimes called 'panentheism,' influenced both Christian mystical theology (particularly the via negativa tradition from Pseudo-Dionysius through Meister Eckhart to the Cloud of Unknowing) and Islamic metaphysics (the Hermetic writings were widely translated into Arabic and influenced Sufi cosmology).

The Emerald Tablet and the Alchemical Tradition

The Emerald Tablet — a brief, cryptic text first appearing in Arabic in the eighth century CE, attributed to Hermes — became the single most important document in the history of alchemy. Its opening axiom, 'As above, so below,' articulates the principle of correspondence that underlies all alchemical (and much magical) practice: that the microcosm mirrors the macrocosm, that terrestrial processes reflect celestial ones, and that the practitioner who understands these correspondences can work transformations at every level. The Tablet's description of the 'One Thing' that rises from earth to heaven and descends again, 'receiving the force of things above and below,' was interpreted as describing the philosopher's stone, the universal medicine, the process of spiritual transformation, and (by Isaac Newton, who translated the text multiple times) the force of gravity itself.

From the Hermetic alchemical tradition emerged the practical knowledge that would eventually develop into modern chemistry: the distillation of acids and alcohols, the preparation of mineral medicines, the classification of substances by their properties, and the experimental method of systematic trial and careful observation. Jabir ibn Hayyan's eighth-century alchemical writings, explicitly Hermetic in framework, introduced systematic experimentation to the study of matter. The Hermetic insistence that theory must be verified through practice — 'the operation of the Sun,' as the Emerald Tablet calls it — was a crucial antecedent of the scientific method.

Astrological and Magical Technologies

The technical Hermetica include detailed astrological treatises that transmitted Egyptian decan astrology, planetary hours, and electional astrology (the art of choosing auspicious times for action) to the Greek, Arabic, and Latin worlds. The Hermetic doctrine of cosmic sympathy — that every terrestrial substance, plant, animal, and mineral corresponds to a specific planet, star, or constellation — provided the theoretical framework for talismanic magic, medical astrology, and the doctrine of signatures (that a plant's appearance reveals its medicinal use). The Picatrix (Arabic: Ghayat al-Hakim), the most influential medieval grimoire, is explicitly Hermetic in its theoretical foundations.

The Asclepius contains a famous description of Egyptian priests creating animated statues — drawing divine spirits into material images through precise combinations of herbs, stones, incense, and ritual invocation. This passage became the locus classicus for debates about magical image-making throughout the medieval and Renaissance periods, influencing Marsilio Ficino's three-volume work on natural magic, Cornelius Agrippa's Three Books of Occult Philosophy, and Giordano Bruno's elaborate mnemonic-magical system.

The Hermetic Influence on World Religions

Hermetic ideas penetrated deeply into Christianity, Islam, and Judaism. The Hermetic concept of creation through the divine Word (Logos) resonates with the opening of the Gospel of John ('In the beginning was the Word'). The soul's ascent through the planetary spheres influenced Gnostic cosmology, Dante's Paradiso, and Christian angelology. In Islam, Hermes was identified with the Quranic prophet Idris and the biblical Enoch, and Hermetic cosmology profoundly influenced Ismaili philosophy, Sufi metaphysics, and the Ikhwan al-Safa (Brethren of Purity). In Judaism, the Hermetic tradition intersected with Kabbalistic thought, particularly in the Renaissance synthesis of figures like Pico della Mirandola, who combined Hermetic, Kabbalistic, and Christian mystical themes into a unified theosophy.

Works

The Corpus Hermeticum

The core Hermetic philosophical collection consists of seventeen Greek tractates, probably compiled in the early centuries CE but drawing on earlier material. The most important include:

- Poimandres (Tractate I): The foundational text, describing Hermes's vision of the cosmic Mind (Nous) who reveals the creation of the universe, the fall of the Primal Man into matter, and the path of ascent back to the divine through gnosis. This single text has been called the most influential document in the Western esoteric tradition.

- Asclepius (also known as The Perfect Discourse): A lengthy dialogue between Hermes and Asclepius covering the nature of God, the cosmos, time, the soul, the animated statues, and a famous prophecy of the decline of Egyptian religion and its eventual restoration. Survives in a Latin translation (the Greek original is lost) and in Coptic fragments found at Nag Hammadi.

- The Key (Tractate X): A systematic exposition of Hermetic cosmology and the nature of the Good.

- The Secret Discourse on the Mountain (Tractate XIII): An initiatory dialogue describing the experience of spiritual rebirth (palingenesia), in which the ten 'tormentors' of ignorance are driven out and replaced by the 'powers of God.'

The Emerald Tablet

The Tabula Smaragdina first appears in Arabic in the Kitab Sirr al-Khaliqa (Book of the Secret of Creation), attributed to Apollonius of Tyana but probably composed in the eighth century CE. Its fifteen or so lines became the most cited text in the entire alchemical tradition. Latin translations circulated widely from the twelfth century onward, and virtually every major alchemist — Albertus Magnus, Roger Bacon, Paracelsus, Isaac Newton — produced commentary on this text.

The Technical Hermetica

Beyond the philosophical corpus, a vast body of technical treatises on astrology, alchemy, magic, botany, and medicine was attributed to Hermes Trismegistus. These include:

- The Liber Hermetis (Book of Hermes): An extensive astrological treatise covering the decans, planetary dignities, and methods of prognostication.

- The Centiloquium (Hundred Aphorisms): An astrological text attributed to Hermes, widely circulated in medieval Europe.

- The Kyranides: A collection of magical-medical recipes organizing the natural world by correspondences between stones, plants, birds, and fish.

- Various alchemical treatises preserved in Arabic and Latin, including works on the preparation of elixirs, the properties of metals, and the creation of the philosopher's stone.

The Stobaeus Fragments

John of Stobi (Stobaeus), a fifth-century CE compiler, preserved extensive fragments of Hermetic writings not included in the Corpus Hermeticum. These include dialogues between Hermes and Tat, Hermes and Asclepius, and Isis and Horus, covering topics from cosmogony to embryology to the nature of the soul. The Kore Kosmou (Virgin of the World) is the most extensive of these fragments, presenting a cosmological myth in which Isis instructs Horus on the origin of human souls.

The Nag Hammadi Hermetic Texts

The discovery of the Nag Hammadi Library in 1945 yielded several Hermetic texts, including the Discourse on the Eighth and Ninth — an initiation text describing the ascent of the soul through the celestial spheres — and a Coptic translation of a portion of the Asclepius. These texts confirmed the existence of a living Hermetic community in Egypt and demonstrated the interpenetration of Hermetic and Gnostic traditions.

The Definitions of Hermes Trismegistus to Asclepius

Discovered in an Armenian manuscript and published by Jean-Pierre Mahe in 1978-1982, these aphoristic definitions appear to represent an early phase of the Hermetic tradition, possibly predating the Corpus Hermeticum. They present Hermetic teaching in a condensed, catechetical format.

Controversies

Historical vs. Legendary: The Casaubon Revolution

The most consequential controversy in the history of Hermeticism concerns the date and authorship of the Hermetic texts. For nearly two millennia, Hermes Trismegistus was believed to be a historical sage of extreme antiquity. The Church Fathers cited him as a pagan prophet who anticipated Christian doctrine. Marsilio Ficino, translating the Corpus Hermeticum for Cosimo de' Medici in 1463, believed he was recovering the original wisdom of humanity. This belief was central to the Renaissance worldview: Hermes stood at the head of a prisca theologia that had transmitted divine wisdom through an unbroken chain from Egypt through Pythagoras and Plato to Christ.

In 1614, the Genevan philologist Isaac Casaubon published De rebus sacris et ecclesiasticis exercitationes XVI, in which he demonstrated on linguistic and historical grounds that the Corpus Hermeticum could not be pre-Christian. The Greek vocabulary, philosophical concepts, and literary forms all pointed to composition in the early centuries of the Common Era. This dating has been overwhelmingly confirmed by subsequent scholarship, though the precise dates of individual tractates remain debated (the consensus range is approximately 100-300 CE).

The Casaubon dating is often presented as a simple debunking, but the reality is more nuanced. Casaubon showed that the surviving Greek texts are post-Christian, but he did not — and could not — prove that they contain no genuinely ancient Egyptian content. Modern scholarship (Fowden 1986, Bull 2018) has increasingly recognized significant Egyptian elements in the Hermetica, including temple theology, initiatory structures, and cosmological concepts that may indeed trace back to pharaonic traditions, even if their Greek literary expression is Hellenistic or Roman.

Egyptian vs. Greek: The Origins Debate

Closely related to the dating question is the ongoing debate about the cultural origins of Hermetic thought. Earlier twentieth-century scholarship (A.D. Nock and A.-J. Festugiere's landmark 1945-54 edition) tended to view the Hermetica as essentially Greek philosophy in Egyptian dress — Platonism and Stoicism with an exotic veneer. This 'Greek' reading minimized the Egyptian elements as superficial coloring.

More recent scholarship has pushed back strongly. Garth Fowden's The Egyptian Hermes (1986) situated the Hermetic tradition firmly within the context of Egyptian temple culture, arguing that the texts reflect the real practices and beliefs of Egyptian priestly communities adapting their traditions to a Hellenized world. Christian Bull's The Tradition of Hermes Trismegistus (2018) goes further, arguing that the Poimandres and other key texts are best understood as translations or adaptations of Egyptian cosmological texts, and that the Hermetic tradition represents a genuine survival of Egyptian wisdom rather than a Greek invention.

Hermeticism and Christianity: Ally or Adversary?

The relationship between Hermetic and Christian thought has been contentious since late antiquity. The Church Fathers were divided: Lactantius enthusiastically cited Hermes as a prophetic witness to Christian truth, while Augustine, in The City of God, condemned the magical and theurgic aspects of the Asclepius even while acknowledging its theological insights. During the Renaissance, this ambiguity erupted into genuine conflict. Giordano Bruno used Hermetic philosophy to mount a radical challenge to Christian orthodoxy, arguing that the Egyptian religion described in the Asclepius was superior to Christianity — a position that contributed to his execution in 1600. The Church's suppression of Bruno, along with the Casaubon dating, helped marginalize Hermeticism within mainstream Christianity, though it continued to flourish in esoteric circles.

The Kybalion Problem

In the modern period, the most contentious issue within Hermeticism is the relationship between the genuine Hermetic corpus and The Kybalion (1908), a popular text by William Walker Atkinson writing as 'The Three Initiates.' The Kybalion's 'Seven Hermetic Principles' (Mentalism, Correspondence, Vibration, Polarity, Rhythm, Cause and Effect, Gender) have become widely identified with 'Hermeticism' in popular culture, but they derive primarily from nineteenth-century New Thought philosophy rather than from the ancient Hermetica. Scholars of the Hermetic tradition consistently distinguish between the two, while many modern practitioners treat The Kybalion as a valid expression of Hermetic wisdom.

Appropriation and Gatekeeping

The Hermetic tradition has been claimed by a bewildering array of organizations and movements — Rosicrucians, Freemasons, the Golden Dawn, Theosophists, New Age practitioners, chaos magicians, and various initiatory orders — each asserting privileged access to the 'real' Hermetic teaching. Questions of legitimacy, lineage, and interpretation have generated intense controversy, particularly around claims of secret oral traditions supposedly transmitted from Egyptian priests to modern initiates. Academic scholarship has generally been skeptical of such claims while acknowledging the genuine continuity of Hermetic ideas across centuries of transmission.

Notable Quotes

Legacy

The legacy of Hermes Trismegistus is arguably the most far-reaching of any figure in Western intellectual history, real or legendary. The Hermetic tradition forms the deep substrate beneath Western esotericism, alchemy, astrology, magic, and significant currents in philosophy, theology, and science.

The Renaissance Transformation

Ficino's 1471 translation of the Corpus Hermeticum as Pimander was a cultural event of the first magnitude. It established Hermes Trismegistus as the fountainhead of wisdom and provided the philosophical framework for the Renaissance revival of magic, astrology, and alchemy as legitimate intellectual pursuits. Pico della Mirandola's Oration on the Dignity of Man (1486) — often called the manifesto of Renaissance humanism — is deeply Hermetic in its vision of the human being as a microcosm capable of ascending to divine status or descending to animal nature. Pico's 900 theses, which he offered to defend publicly in Rome, included numerous propositions drawn from the Hermetica, and his synthesis of Hermetic, Kabbalistic, and Christian mystical thought created a template that would endure for centuries.

Giordano Bruno (1548-1600) pushed the Hermetic vision further than anyone before or since, developing an elaborate system of Hermetic magic, memory arts, and cosmological speculation that challenged the boundaries of Christian orthodoxy. His execution by the Inquisition in 1600 marks the moment when Hermetic thought became definitively dangerous in Catholic Europe, though it continued to flourish in Protestant and esoteric circles.

The Alchemical and Scientific Legacy

The entire tradition of Western alchemy — from Jabir ibn Hayyan in the eighth century through the medieval Latin alchemists to Paracelsus, Robert Boyle, and Isaac Newton — operates within a Hermetic framework. The alchemical quest for the philosopher's stone, the universal medicine, and the transmutation of metals is predicated on the Hermetic principles of cosmic sympathy and correspondence. When modern chemistry eventually emerged from alchemy in the seventeenth and eighteenth centuries, it retained the Hermetic emphasis on experimental practice and the systematic study of material transformation, even as it discarded the spiritual and cosmological framework.

Newton's alchemical manuscripts — over a million words, unpublished during his lifetime and largely suppressed after his death — reveal that the founder of classical physics was profoundly immersed in Hermetic thought. His concept of gravity as a force operating across empty space (what his contemporaries called 'action at a distance') was influenced by the Hermetic doctrine of cosmic sympathy and universal correspondence. The historian of science Betty Jo Teeter Dobbs has argued persuasively that Newton's alchemy and physics were not separate pursuits but aspects of a unified Hermetic program.

The Esoteric Orders

Virtually every major Western esoteric organization claims Hermetic lineage. The Rosicrucian manifestos of 1614-1616 presented their brotherhood as heirs to Hermetic wisdom. Freemasonry incorporated Hermetic symbolism into its ritual framework, particularly in the higher degrees of the Scottish Rite. The Hermetic Order of the Golden Dawn (founded 1888) made Hermeticism the explicit foundation of its magical system, synthesizing Hermetic cosmology with Kabbalistic, astrological, and Enochian elements into an elaborate initiatory curriculum. Aleister Crowley's Thelema, Dion Fortune's Society of the Inner Light, and the broader ceremonial magic tradition all operate within Hermetic frameworks.

The Islamic Transmission

In the Islamic world, Hermes Trismegistus was identified with the Quranic prophet Idris (Quran 19:56-57, 21:85) and the biblical patriarch Enoch. Arabic translations of Hermetic texts — both the philosophical Hermetica and the technical writings on alchemy, astrology, and magic — circulated widely from the eighth century onward. The Hermetic tradition profoundly influenced Ismaili cosmology (particularly in the works of the Ikhwan al-Safa), Sufi metaphysics (the doctrine of the Perfect Man in Ibn Arabi bears Hermetic traces), and Islamic science. The concept of the philosopher's stone passed from the Hermetic tradition through Arabic alchemy into Latin Europe, and the astronomical observations of Islamic scientists were conducted within astrological frameworks that owed much to the Hermetic tradition.

Modern Influence

In the modern period, Hermetic ideas continue to exert influence through multiple channels. Helena Blavatsky's Theosophy drew extensively on Hermetic cosmology. Carl Jung interpreted alchemical symbolism as expressions of the individuation process, bringing Hermetic imagery into the mainstream of depth psychology. The New Age movement's concepts of 'vibration,' 'manifestation,' 'as above, so below,' and the correspondence between microcosm and macrocosm are all Hermetic in origin, even when their practitioners are unaware of the source. And in academic philosophy, the Hermetic tradition has received renewed attention as scholars recognize its importance for understanding the development of Western thought — from the Renaissance to the Scientific Revolution to the Romantic reaction against Enlightenment rationalism.

The enduring power of Hermes Trismegistus lies precisely in the ambiguity of his nature: neither fully historical nor fully mythical, neither purely Egyptian nor purely Greek, neither purely religious nor purely philosophical, he represents the possibility of a unified wisdom that encompasses all domains of human knowledge. In an age of increasing specialization and fragmentation, the Hermetic vision of cosmic unity retains its appeal — and its challenge.

Significance

The significance of Hermes Trismegistus radiates across the entire history of Western esotericism, philosophy, science, and religion. No single figure — real or legendary — has exerted a more pervasive influence on the hidden counter-tradition that runs alongside mainstream Western thought.

The Prisca Theologia and the Authority of Antiquity

For nearly two millennia, Hermes Trismegistus was believed to be a historical sage of immense antiquity — a contemporary or predecessor of Moses, perhaps even a contemporary of Abraham. The Church Fathers, including Clement of Alexandria, Lactantius, and Augustine, cited the Hermetica as evidence that pagan wisdom had anticipated Christian revelation. Lactantius (c. 250-325 CE) called Hermes 'almost as old as the gods themselves' and quoted Hermetic passages on the Son of God and the creation by the Word as prophecies of Christ. This extraordinary claim — that a pagan Egyptian sage had known divine truths before the Hebrew prophets — gave Hermetic wisdom unique authority in the Christian intellectual world.

When Marsilio Ficino received a Greek manuscript of the Corpus Hermeticum in 1460, Cosimo de' Medici ordered him to translate it before continuing his work on Plato — an astonishing priority that reflects the reverence in which Hermes Trismegistus was held. Ficino's Latin translation, published as Pimander in 1471, ignited the Renaissance Hermetic revival that would shape European culture for the next two centuries. The concept of the prisca theologia — an ancient, unified wisdom tradition stretching from Hermes through Orpheus, Pythagoras, and Plato to Christ — became a dominant intellectual framework, influencing Pico della Mirandola, Giordano Bruno, John Dee, Robert Fludd, and Isaac Newton.

Isaac Casaubon's philological demonstration in 1614 that the Hermetic texts were post-Christian compositions rather than pre-Mosaic prophecies was a landmark in critical scholarship, but its impact was slower and less complete than often supposed. Many continued to believe in the essential antiquity of Hermetic wisdom even after accepting the late date of the surviving texts — arguing, not unreasonably, that the philosophical content might preserve genuinely ancient Egyptian teachings even if the Greek literary form was comparatively recent. Modern scholarship has increasingly vindicated this position: the work of Garth Fowden (The Egyptian Hermes, 1986) and Christian Bull (The Tradition of Hermes Trismegistus, 2018) demonstrates significant Egyptian temple influence in the Hermetic corpus.

Alchemy and the Transmutation Tradition

Hermes Trismegistus is universally regarded as the father of alchemy. The Emerald Tablet — with its famous axiom 'That which is above is like that which is below, and that which is below is like that which is above, to accomplish the miracles of the One Thing' — became the foundational text of the alchemical tradition, interpreted as describing both the transmutation of metals and the spiritual transformation of the practitioner. The term 'hermetic seal' (from which we derive 'hermetically sealed') refers to the alchemical practice of sealing vessels with the sigil of Hermes. Arabic alchemists — Jabir ibn Hayyan (Geber), al-Razi, and others — explicitly worked within the Hermetic framework, and their Latin translations transmitted this tradition to medieval Europe, where it influenced Paracelsus, the Rosicrucians, and ultimately the development of modern chemistry.

Astrology, Magic, and the Occult Sciences

The technical Hermetica — distinct from the philosophical Corpus Hermeticum — include extensive treatises on astrology, sympathetic magic, talismanic image-making, and the animation of statues through theurgic ritual. The Asclepius contains a famous passage describing how Egyptian priests created living statues inhabited by divine forces — a passage that profoundly influenced Renaissance magical theory and practice. The astrological Hermetica transmitted the Egyptian system of decans (36 ten-degree divisions of the zodiac) that remains fundamental to astrological practice. And the principle of cosmic sympathy — that connections of likeness and resonance link all levels of reality, allowing the practitioner to draw down celestial influences through appropriate materials, symbols, and rituals — is essentially Hermetic in origin and pervades the entire Western magical tradition.

Influence on Western Science

Paradoxically, the Hermetic tradition — often dismissed as 'magical thinking' — played a crucial role in the development of modern science. Frances Yates's influential (if debated) thesis in Giordano Bruno and the Hermetic Tradition (1964) argued that the Hermetic vision of the human being as a cosmic operator — empowered by knowledge to work upon nature — provided a crucial psychological impetus for the scientific revolution. Whether or not one accepts Yates's specific claims, it is undeniable that figures central to the emergence of modern science — Copernicus, Kepler, Newton — were deeply influenced by Hermetic ideas. Newton's alchemical manuscripts (comprising over a million words) reveal a lifelong engagement with the Hermetic tradition, and his concept of gravity as action at a distance owes something to the Hermetic principle of cosmic sympathy.
