What the tradition transmits cannot be received at second hand. The Library exists for those who wish to go to the sources directly — not as a prerequisite to reading the Corpus, but as a parallel movement: the encounter with the primary texts that the Corpus engages, in the editions and translations that preserve what matters.
Here you will find two territories.
The first: the sources the Corpus cites directly — the texts whose specific formulations appear in the articles, whose precise distinctions the work depends upon. These are not recommendations. They are the intellectual ground of what the archive produces.
The second: the wider formation territory — the texts that inform the thinking without necessarily appearing in the citations. Ancient philosophy before Neoplatonism. Mystical traditions across three continents. Phenomenology. Literature as philosophical thought. These are the sources that make the work what it is, visible to those who wish to understand not only what the Corpus argues but how it arrived at its arguments.
What you find here will not be found in popular reading lists. That is not incidental.
The foundational texts of depth psychology and archetypal theory.
Adolf Guggenbühl-Craig
Irreplaceable for this angle. No other author treats with this rigor the structural paradox of the wounded healer as a problem of power — the tendency of the healer to project the wound onto the client and remain in the role of the whole one. Completely distinct from Hillman and Kerényi. Indispensable for Article 10 (Hillman and Soul) and academic working papers directed at clinical psychologists.
Spring Publications, 1971
C.G. Jung
The Bollingen Series edition. Begin with Volume 9 (Archetypes) and Volume 12 (Psychology and Alchemy).
Bollingen Series, Princeton University Press
James Hillman
The chapter on 'The Healing Function' reframes pathology as a mode of soul-making.
Harper & Row, 1975
James Hillman
The most rigorous treatment of the relationship between Eros and psychological knowledge. The chapter on Eros and Psyche is the primary source for any treatment of love as the force that moves individuation.
Northwestern UP, 1972
Marie-Louise von Franz
Von Franz's clarity makes complex material accessible without simplification.
Shambhala, 1994
Edward Edinger
Essential for understanding the relationship between individual ego and transpersonal Self.
Penguin, 1973
Erich Neumann
Traces the development of consciousness through mythological stages.
Princeton UP (Bollingen), 1954
Erich Neumann
The ethics of the ego (ethics of repression and Persona) produced the collective catastrophes of the 20th century; the new ethics demands that the individual assume responsibility for the contents of their own Shadow rather than projecting them collectively.
Hodder & Stoughton, 1949 / Princeton UP (Bollingen), 1969
Wolfgang Giegerich
Radicalizes Jung's position: the Shadow is not what the ego refused — it is what the logic of the soul demands remain in tension with consciousness. Philosophically more precise than the conventional clinical formulation.
Peter Lang, 1998
The ancient sources of Western esotericism — Hermes Trismegistus, Paracelsus, Ficino.
Hermes Trismegistus
The Clement Salaman translation preserves the poetic quality while remaining accessible.
Clement Salaman translation, Inner Traditions, 2004
Proclus
Systematizes the Neoplatonic ontology that Plotinus left in meditative form — 211 propositions with demonstration. For synthesis articles (17-24) treating the relation between depth psychology and metaphysics, this is the source that confers conceptual precision. Cite by proposition: (Procl. ET §35).
Dodds (Oxford UP, 2nd ed., 1963)
Marsilio Ficino
The Renaissance synthesis that brought Platonism into dialogue with Christianity.
I Tatti Renaissance Library, Harvard UP
Agrippa von Nettesheim
The comprehensive Renaissance manual of natural, celestial, and ceremonial magic.
Tyson edition, Llewellyn, 1993
The Platonic tradition from Plotinus to Proclus — the soul's procession and return.
René Guénon
Articulates the metaphysics of the primordial tradition with a rigor no other modern Western author achieved. The Multiple States of the Being treats the ontology of states of being — directly relevant to the Jungian distinction between ego, Self, and collective unconscious — with non-psychological precision. The Reign of Quantity is the most rigorous diagnosis of modernity's ontological inversion. Uses precise metaphysical terminology: Principle, Manifestation, Universal Possibility, Being and Non-Being in the metaphysical sense.
Sophia Perennis, 2001
Frithjof Schuon
Complements Guénon with greater attention to what tradition demands of the subject who inherits it — not only its ontological structure. The Transcendent Unity articulates the distinction between exoterism (exterior form of tradition) and esoterism (common metaphysical nucleus) — directly relevant to the archive's positioning of hermeticism, Neoplatonism, and depth psychology as expressions of a single territory. When citing, always use 'Intellect' with capital to signal the technical sense (nous, faculty of perception of the principle).
Quest Books, 1984 / Sophia Perennis, 2009
Plotinus
The philosopher who articulates with greatest precision the ontology sustaining both depth psychology and the hermetic tradition: the soul as a level of reality participating simultaneously in superior (Nous, One) and inferior (matter) levels. Cite by Ennead, tractate, and paragraph. Ex: (Enn. I.6.9). Armstrong (Loeb) for academic citation; MacKenna for accessibility.
Armstrong (Loeb, Harvard UP, 7 vols., 1966-1988) / MacKenna (Faber & Faber, 1956)
Aldous Huxley
Huxley is not a metaphysician in the sense of Guénon or Schuon — he is a high-quality systematizer and communicator of the perennial tradition. The Perennial Philosophy is the most accessible and most cited anthology of the tradition — the archive can use Huxley as a bridge for the Scholar reader who does not yet have the vocabulary of Guénon. Never cite as primary philosophical authority — cite as accessible confirmation of a position that the primary source sustains with greater rigor. Use restricted to entry articles (1-8).
Harper & Row, 1945
Martin Heidegger
The concepts of Dasein as being-in-the-world (not subject enclosed in itself but openness to being), Aletheia as un-concealment (truth not as correspondence but as revelation of what was hidden), and Eigentlichkeit (authenticity as appropriation of one's own being) are the most precise philosophical language available for what Jungian individuation describes at the psychological level. ⚠️ EDITORIAL RESTRICTION: The archive cites Heidegger exclusively by technical concepts relevant to his ontology of existence — never by passages that may be associated with his political positions (1933-1945). The editor verifies systematically that no citation comes from the Black Notebooks or texts from 1933-1945.
Macquarrie & Robinson (Harper & Row, 1962) / Hofstadter (Harper & Row, 1971)
Iamblichus
The philosopher who transformed Neoplatonic philosophy into theurgy — ritual praxis as a form of ontological ascent. The central argument that contemplation is not sufficient, that operative praxis is necessary for real transformation, is exactly the position distinguishing this archive. Cite by book and paragraph: (Iambl. Myst. II.11).
Clarke, Dillon & Hershbell (Society of Biblical Literature, 2003)
Works exploring the imaginal realm, symbolic consciousness, and mythic structure.
Henry Corbin
Introduces the mundus imaginalis — the intermediate world between sense and intellect.
Omega Publications, 1978
Mircea Eliade
On the manifestation of the sacred in space, time, and nature.
Harcourt Brace, 1959
Roberto Calasso
A literary retelling of Greek mythology that illuminates psychological dimensions.
Knopf, 1993
Ancient philosophy as transformation of the soul — not theory but way of life.
Pierre Hadot
Shows that ancient philosophy was not theory but a way of being. The foundational text for understanding spiritual exercises as the core of ancient philosophical practice.
Blackwell, 1995
Pierre Hadot
The most rigorous treatment of the Meditations as a notebook of spiritual exercises — indispensable for understanding Marcus Aurelius as practice rather than doctrine.
Harvard UP, 1998
Pierre Hadot
The most accessible synthesis of Hadot's argument about ancient philosophy as a way of life — useful for entry articles (1-8) before the authority articles (9-16).
Harvard UP, 2002
Plato
The Phaedo is the primary source for the psychology of the soul as territory of work and death as askesis. The Symposium is the source of Eros as a force of ontological ascent — indispensable for The Hermetic Tradition and Individuation. The Republic (Books VI-VII, the allegory of the cave) is the source of the distinction between appearance and reality as an existential problem. The Timaeus is the source of the Anima Mundi that hermeticism and Neoplatonism develop. Cite by dialogue and Stephanus step: (Pl. Phd. 64a) or (Pl. Smp. 210a).
Gallop (Oxford UP, 1975) / Nehamas & Woodruff (Hackett, 1989) / Grube (Hackett, 1992) / Zeyl (Hackett, 2000)
Marcus Aurelius
The emperor's private journal — not a treatise but a living document of spiritual exercise. Cite Farquharson (Oxford UP) for academic precision, Hays (Modern Library) for accessibility. Cite by book and aphorism: (Med. IV.3).
Farquharson (Oxford UP, 1944) / Hays (Modern Library, 2002)
Epictetus
On distinguishing what is within our control from what is not. The Enchiridion for entry articles; the Discourses for authority articles. Cite by book and chapter: (Disc. I.1) or (Ench. 1).
Hard (Oxford UP, 2014)
Seneca
Practical guidance on living well, facing death, and cultivating wisdom. The most directly relevant letters are I (on time), XII (on old age and death), and LXXVII (on the sufficiency of the good). Cite by epistle number: (Ep. XII.1).
Grummere (Loeb, 3 vols.)
Epicurus
Epicurus is not the philosopher of pleasure that popular reception suggests — he is the philosopher of melete thanatou (exercise of attention to death) and the deliberate cultivation of friendship and the present as response to the dissolution of the illusion of permanence. The Letter to Menoeceus is the most direct text on philosophy as transformation of the relation to death. Cite by Inwood-Gerson collection: (Ep. Men. 124), (KD I).
Inwood & Gerson, The Epicurus Reader (Hackett, 1994)
The mythic foundations of archetypal psychology — gods as presences, not symbols.
Joseph Campbell
Read alongside Jung on archetypes to understand personal and collective patterns. The foundational text for the monomyth structure.
Princeton UP (Bollingen), 1949
Joseph Campbell
Comparative analysis of mythologies by civilization. Indispensable for depth and synthesis articles treating specific mythologies beyond the monomyth. Use selectively: Occidental Mythology for the European context of the archive; Creative Mythology for the relation between myth and creative individuation.
Viking Press, 1959-1968
Walter F. Otto
The phenomenologist of Greek religion who preceded Kerényi and influenced both Eliade and Hillman. His analysis of Dionysus as the god who dissolves the boundaries of the ego is the primary source for any treatment of the collective Shadow in mythical context. The argument: the Greek gods were real presences for the Greeks, not symbols.
Indiana UP, 1965 / Pantheon Books, 1954
The Corpus is the work. The Library is its ground. Both are open.
