Mysticism

← Encyclopedia

Mysticism is the claim, and the practice built on it, that the ultimate reality behind ordinary life can be reached directly — known or united with in experience rather than reasoned toward or merely believed. A creed is held; a proof is followed; the ultimate that mysticism speaks of is, on the testimony of those who pursue it, arrived at. The word gathers a great range of such claims under a single heading, and most of the difficulty in the subject lies in that gathering. What it names within each tradition is precise. What it names across them is a question that has occupied a century of scholarship and is not the same question at all.

The distinction is worth holding from the start, because the noun does double duty. There is the thing — the contemplative’s actual route to the highest reality, formulated in gnosis, apprehended in silence, and described in vocabularies that do not translate cleanly into one another. And there is the category — the late, comparative container into which European observers swept all such routes at once. The two are not rivals. They are different objects, and the entry returns to that difference at its end.

The word and the thing it names

The English term is younger than the thing it names. “Mystical” descends from the Greek mystikos — hidden, pertaining to the mysteries — the word for what was disclosed only to initiates of the Eleusinian and other mystery rites, shielded from the uninitiated by a vow of silence. The early Church took the adjective and turned it inward. Mystikos came to describe the concealed spiritual meaning beneath the letter of scripture, and the hidden significance carried within the rites — the “mystical” sense of a psalm, the “mystical” body present in the bread. The word marked a depth, not yet a discipline.

The discipline acquired a name around the year 500, in the writings ascribed to Dionysius the Areopagite. His short treatise The Mystical Theology set out a mystical knowing of God reached not by adding true statements about the divine but by stripping them away — an ascent through negation (apophasis) in which every name for God, even “goodness” and “being,” is denied in turn until the soul stands in a luminous darkness, in an unknowing (agnōsia) that is the highest knowing available to a creature. This is the taproot of Christian apophatic theology, and it fixed the shape that “mystical” would carry for a thousand years: not an experience reported, but a method of unsaying — a theology pursued past the limit of speech.

The abstract noun “mysticism” is far younger and was made elsewhere. The free- standing substantive — French la mystique, English “mysticism” — emerged only in the seventeenth and eighteenth centuries, as the historian Michel de Certeau showed in La Fable mystique (1982): where the medievals had spoken of an adjectival mystical theology, the early-modern period detached the adjective and made it a noun, a thing one could possess, study, suspect. It surfaced amid the Quietist controversies that convulsed Catholic France, often on the lips of critics, to label a kind of interior religion the authorities found difficult to govern. By the time the English word settled into its modern, universal sense — a sense that reaches across every tradition at once — it had been further reshaped by liberal-Protestant and Romantic writers; Leigh Eric Schmidt traces that making in “The Making of Modern ‘Mysticism’” (2003). The category, in short, was assembled partly from the outside, partly by people who did not practice what they were naming, and scholarship has spent the last century arguing over what, if anything, it picks out.

The vocabularies, and what each protects

Within the traditions themselves the vocabulary is exact and various, and the variety is not decorative. Each names a maximal closeness between the human and the ultimate; each, with equal care, erects an internal distinction designed to keep that closeness from collapsing into sheer identity. The distinctions are load-bearing. Flatten them and what remains is not a deeper unity but a thinner one.

The Christian contemplatives — the matter of Christian mysticism — speak of union with God and of an unknowing that passes beyond images and concepts. But union, in the mature Greek formula, is deification by grace, not by nature: the human becomes god through participation in God’s energies, never by sharing God’s essence. The asymmetry between Creator and creature is the doctrine, not an embarrassment to it. The same care governs the most extreme statements; when Meister Eckhart preached a grunt, a single ground in God and in the soul, his Rhineland audacity was tried by Avignon, and the question of what exactly he had claimed has never stopped being argued.

Sufi writers map fanāʾ, the passing away of the self, and baqāʾ, the subsistence in God that follows — the terminus treated within Sufism. Here too a guardrail is built into the grammar. Junayd of Baghdad taught a “second sobriety,” a return from the drunkenness of union to lucid, teaching, law-keeping life, and read the ecstatic cries of his predecessors — Bāyazīd’s Subḥānī!, glory to me — not as claims of identity with God but as utterances spoken through a servant whose attributes had been replaced by God’s. Read as flat identity, such sayings became ḥulūl or ittiḥād, incarnationism or monism, and a heresy a man could be killed for; al-Ḥallāj was executed at Baghdad in 922 after one of them. The servant-Lord asymmetry holds even where experience overruns it. (Al-Ghazālī, who abandoned a celebrated teaching chair to seek the thing directly, belongs to that same world.)

Advaita Vedānta — one pole of the spectrum mapped under Vedanta — holds that the innermost self is not united with the absolute but already identical to it, the difference an illusion (avidyā) to be seen through rather than a gap to be crossed — tat tvam asi, that thou art. Liberation is not produced; it is recognized, a fact that has always obtained, merely veiled. But the same scriptures yield two further readings that the perennial reach tends to soften: Rāmānuja’s qualified non-dualism, in which the freed soul attains the Lord’s bliss yet keeps its distinctness as a mode of Brahman, and Madhva’s dualism, in which liberation is eternal proximity to God and never merger at all. Three schools, one set of verses, three genuinely incompatible metaphysics of liberation.

The Neoplatonists described the soul’s ascent to a wordless contact with the One — a union beyond intellect and beyond being, in which the seer and the seen are no longer two. Plotinus, who reports having reached it rarely and briefly, insists the One can be approached only by shedding everything the mind would predicate of it; the apophatic register of Neoplatonism is the philosophical ancestor of the Dionysian darkness. Each of these vocabularies names something precise, and means it in its own frame. The instinct to read them as one frame in four costumes is exactly the instinct the traditions resist.

The architecture of the route

What recurs across the traditions, beneath the divergent metaphysics, is less a shared content than a shared shape. Mysticism is not, in any of its homes, merely a doctrine to be assented to; it is a route to be walked, and the route has a recognizable architecture. There is a turning-away — the renunciatory discipline that quiets the appetites and clears the field, treated under asceticism; there is the practiced attention, the structured stilling and recollection gathered under meditation; there is, almost everywhere, the bond between a master and a disciple, the teacher who carries the way in a living chain and who tests, forms, and authorizes the one who would walk it. Monasticism and its analogues exist in large part to hold that architecture steady across generations.

The route is also, on the testimony of those who take it, transformative rather than informational. It does not merely tell the seeker something; it changes the one who arrives. The conviction common to the traditions is that the highest reality is approached by a passage discursive thought cannot complete, and that the passage remakes the traveler — which is why the literature is so often a literature of stages, purgations, and dark nights rather than of conclusions. Whether this transformation has a single description is precisely the matter the modern debate could not settle.

Experience, and the turn away from it

Modern scholarship divides over whether the traditions point to one experience or to many — and, more recently, over whether “experience” is even the right thing to be counting. The argument is the proper subject of comparative mysticism; what bears on the category as such is how the argument hollowed the category out.

The perennialist reading, influential in the early twentieth century and elaborated into a metaphysics by the Traditionalist school, held that beneath the doctrines lies a single core experience that the traditions then dress in local clothing. W. T. Stace, in Mysticism and Philosophy (1960), gave the thesis its tidiest form: a universal phenomenology — at its deepest a contentless “introvertive” unity — onto which each tradition lays its own interpretive vocabulary. The constructivist response, launched by Steven Katz’s 1978 essay “Language, Epistemology, and Mysticism,” argued the reverse. There is no raw experience prior to a tradition’s concepts; the mystic’s doctrine, scripture, and training penetrate the experience itself, so that a Buddhist reaching nirvāṇa and a contemplative of Jewish mysticism reaching devequt, the cleaving of the soul to God, do not undergo one thing and describe it two ways — they undergo two things. Robert Forman and others answered with the “pure consciousness event,” a wakeful but contentless state that, having no content, could not be built by concepts; the field’s settled view is that such states may occur but do not, by themselves, prove the strong perennialist claim. John Hick, meanwhile, supplied the dominant pluralist frame: a single transcategorial Real, humanly known only through culturally shaped schemata.

Much recent work has stepped back from the word “experience” altogether. Bernard McGinn, opening his multi-volume history of Western Christian mysticism (1991), deliberately recast the subject as the consciousness of, and preparation for, the immediate presence of God — language meant to escape the modern fixation on private, ineffable inner states. Grace Jantzen, in Power, Gender and Christian Mysticism (1995), pressed harder still: to define mysticism as intense subjective experience, she argued, is itself a construction with a history and a politics, one that kept embodiment, community, and the contests over who counts as a mystic off the scholarly table. The center of gravity has shifted toward the texts, the practices, the institutions, and the disputes that actually produced the claims — toward mysticism as something people did and argued over, rather than a state they privately had.

Sources, editions, and the scholarship

The primary literature of the four great termini is, to a striking degree, available to read directly. For the Christian apophatic taproot, John Parker’s translation of The Works of Dionysius the Areopagite (London: James Parker, 1894–1899) carries The Mystical Theology and the negative-theology chapters of The Divine Names (Parker translation); the fourteenth-century English Cloud of Unknowing, edited by Evelyn Underhill (Watkins, 1912), renders the same Dionysian unknowing into vernacular practice (Underhill edition). For the Neoplatonic ascent, Stephen MacKenna’s The Enneads (Medici Society, 1917–1930) — its fifth volume, carrying Plotinus’s henological treatises on the One, entering the public domain in 2026 — is the standard English Plotinus (MacKenna Enneads). For Advaita, George Thibaut’s translation of the Vedānta-Sūtras with Śaṅkara’s commentary in the Sacred Books of the East (Oxford, 1890–1896) remains the spine of the English-language neti neti (Thibaut, SBE). For the Sufi stations, R. A. Nicholson’s translation of al-Hujwīrī’s Kashf al-Maḥjūb (Gibb Memorial Series, 1911) is the earliest full English map of fanāʾ and baqāʾ and the disciplines around them (Nicholson, Kashf al-Maḥjūb); and Claud Field’s The Confessions of al-Ghazzali (Wisdom of the East, 1909) carries the autobiographical account of a scholar leaving the lecture hall for the path (Field, Confessions).

The framing literature is the other half of the subject. The early-twentieth- century studies that built the modern English category remain in print and in the public domain: William James’s The Varieties of Religious Experience (Longmans, 1902; Project Gutenberg), with its four marks of the mystical state — ineffability, noetic quality, transiency, passivity; W. R. Inge’s Christian Mysticism (Methuen, 1899; Project Gutenberg), which embedded the Christian stream in its Plotinian spine; and Evelyn Underhill’s Mysticism (Methuen, 1911), which mapped the contemplative life as a sequence of stages. The decisive twentieth-century debate runs through W. T. Stace, Mysticism and Philosophy (Macmillan, 1960); Steven T. Katz, ed., Mysticism and Philosophical Analysis (Oxford University Press, 1978), the locus of the constructivist turn; Robert K. C. Forman, ed., The Problem of Pure Consciousness (Oxford University Press, 1990); and John Hick, An Interpretation of Religion (Yale University Press, 1989). The reconception of the field is carried by Bernard McGinn’s The Foundations of Mysticism (Crossroad, 1991), the first volume of The Presence of God; Michel de Certeau’s La Fable mystique (Gallimard, 1982), on the early-modern invention of la mystique as a noun; Grace M. Jantzen’s Power, Gender and Christian Mysticism (Cambridge University Press, 1995); and Leigh Eric Schmidt’s “The Making of Modern ‘Mysticism’,” Journal of the American Academy of Religion 71, no. 2 (2003): 273–302 (DOI). Among comparativists, William Chittick’s work on Ibn ʿArabī, Anantanand Rambachan’s on Advaita, and Bernard McGinn’s on Eckhart are the studies that established what each tradition will not let go of before asking what, across them, might still be shared.

The category as an instrument

To call something “mysticism” is to use a tool that was forged late and far from the workbench it now sorts. The contemplatives of Scetis and Strasbourg, of Baghdad and Śṛṅgeri, of the Plotinian school at Rome, did not file their disciplines under a common heading; the heading was supplied afterward, in European argument, by readers deciding which interior religion to admire and which to fear. That history does not make the category empty — a tool made for one purpose can do real work at another — but it does set the terms on which the work is honest. The category is a comparative instrument, and an instrument is answerable to what it is used for: it earns its keep when it lays the vocabularies side by side so that tat tvam asi and the Dionysian darkness and the second sobriety of Junayd can be read against one another with their distinctions intact, and it forfeits its keep the moment it presses them into a single shape they were each built to refuse. Used the first way, “mysticism” opens a conversation between strangers who would never have called themselves by one name. Used the second, it makes them all say the thing the word was coined to want them to say. The instrument is the same; the discipline lies in knowing which use is in hand.
