Archetypal Grammar designates the structural, pre-formal logic by which archetypes organize psychic and cultural life — not as fixed contents but as generative schemas that constrain the range of possible expressions without determining any single one. The concept draws its central force from Jung's crystallographic analogy: the archetype functions as an 'axial system' that preforms structure in the mother liquid without itself possessing material existence, a 'facultas praeformandi' inherited in form alone. Post-Jungian elaborations extend this insight in several directions. Conforti grounds archetypal grammar in morphogenetic field theory, arguing that all relational and biological systems replicate fidelity to original archetypal form. McGovern translates it into predictive-processing neuroscience, proposing that archetypes are instantiated through hierarchical generative models operating across cortical and subcortical systems. Peterson pursues a philological vector, locating archetypal grammar in the Middle Voice of ancient Greek — the grammatical scaffold that once sustained a third modality of soul between pure agency and pure passivity, a scaffold whose erosion in Latin left Western psychology structurally impoverished. Allan's cognitive-linguistic analysis of schematicity in Greek grammar provides indirect support: abstract schemas and their elaborations constitute a layered architecture directly analogous to what depth psychology calls archetypal patterning. The central tension in the literature is between formalist readings — archetype as empty schema — and dynamist readings, wherein form already carries affective and numinous charge. Both positions converge, however, on the claim that psychic life is rule-governed at a level deeper than personal experience.

archetypes are not determined as regards their content, but only as regards their form and then only to a very limited degree… the archetype in itself is empty and purely formal, nothing but a facultas praeformandi, a possibility of representation which is given a priori
Jung's locus classicus for archetypal grammar: archetypes furnish formal constraints — an inherited syntax of representation — without supplying semantic content, making them structural laws rather than images.
Jung, Carl Gustav, The Archetypes and the Collective Unconscious, 1959thesis
the form of an archetype to the axial system of a crystal, which, as it were, preforms the crystalline structure in the mother liquid, although it has no material existence of its own… The archetype in itself is empty and purely formal, nothing but a facultas praeformandi
Papadopoulos consolidates Jung's formal-grammar thesis by emphasizing the archetype's role as a preformative structure that organizes matter without itself being material.
Papadopoulos, Renos K., The Handbook of Jungian Psychology: Theory, Practice and Applications, 2006thesis
As the Middle Voice eroded, the Western mind lost the grammatical scaffolding necessary to sustain the thūmos. Latin, with its juridical preference for clear lines of agency, enforced a stark binary: one is either the Agent or the Patient
Peterson argues that the loss of the Greek Middle Voice constitutes a literal destruction of archetypal grammar — the syntactic structure through which soul could hold a third, self-reflexive position between action and passivity.
Peterson, Cody, The Abolished Middle: Retrieving the Thumotic Soul from the Unconscious, 2026thesis
beneath the political maneuvering lay a theological question with deep grammatical roots: What is the structure of the human soul?
Peterson locates the formal codification of the soul's archetypal grammar — its tripartite or bipartite structure — as the real stakes of the Fourth Council of Constantinople.
Peterson, Cody, The Abolished Middle: Retrieving the Thumotic Soul from the Unconscious, 2026thesis
archetypes 'as such' and archetypal 'images' are instantiated via a prediction cascade over various cortical and subcortical systems… via a 'trilogical interplay' involving the high-level cortex, the low-level cortex, and subcortical/affective systems
McGovern recasts archetypal grammar as a neuropsychological generative architecture — a hierarchical prediction cascade that constitutes the biological substrate of archetypal patterning.
McGovern, Hugh, Eigenmodes of the Deep Unconscious: The Neuropsychology of Jungian Archetypes and Psychedelic Experience, 2025thesis
all relationships — be it a marriage, the therapeutic dyad, or a corporate structure — expressive of an underlying, archetypal dynamic… from the corresponding form, infer the nature of the constellated archetype
Conforti extends archetypal grammar from intrapsychic structure to relational and institutional fields, arguing that any form can be read as a surface expression of an underlying archetypal syntax.

You could call the archetype the 'nature constant' of the human psyche. It is eminently conservative… each new expression of the archetype maintains a fidelity to its original form
Conforti, drawing on von Franz, frames archetypal grammar as morphogenetic conservatism — a law of formal replication analogous to DNA patterning that persists across culturally variable expressions.

abstract schemas and specific expressions are part of the grammar, provided that they have become conventional units, through entrenchment by frequent, repeated occurrence
Allan's cognitive-linguistic account of schematic hierarchies in grammar provides a structural parallel to archetypal grammar, showing how abstract preformative schemas coexist with and generate their specific instantiations.

the specific content of archetypal representations naturally varies according to cultural context, but the same underlying themes are apparent… i.e. in their most
McGovern affirms the form/content distinction central to archetypal grammar: cultural variation in surface content is consistent with invariant underlying structural themes.

The Passive Voice says: 'I am destroyed by this.'… What remains when both doors are closed is the Middle: menō kai tlēsomai algea paschōn — 'I will remain and I will endure, suffering griefs'
Peterson demonstrates archetypal grammar in action through Homeric usage, showing the Middle Voice as the syntactic form of a psychic posture — neither omnipotent agency nor total collapse — that depth psychology must recover.

regardless of their personal experiences, these aliens would be struck by these observations and realize that the majority of earthlings care for their Jung… the core activities undertaken in the pursuit of this goal remain a constant. This is the ontology of the archetype
Conforti's thought experiment illustrates archetypal grammar as a cross-cultural formal constant visible in behavioral patterns irrespective of individual or cultural variation.

cultures produce artefacts — myths, rituals, and objects of various kinds — and that these artefacts have to be taken into account when viewing evolution in that culture… evolution under natural selection no longer takes place in relation to the natural environment alone, but also in relation to the artefactual environment
Hogenson's Baldwin Effect thesis implies that archetypal grammar is partially encoded in cultural artefacts, situating the formal constraints of archetype within a co-evolutionary, niche-constructing framework.

If value were a preexisting truth — whether as Platonic Form or Jungian Archetype — the gods, who 'know all things,' would already possess it. But value requires a physical history of feeling accumulation that divine nature cannot replicate
Peterson challenges purely formalist readings of archetypal grammar by insisting that the grammar of value must be instantiated through bodily, temporal experience — form alone cannot generate the felt weight of meaning.

Plato performs a catastrophic misreading of the anatomy that ushers in what James Hillman identified as the 'ages of repression.' He relocates the 'Rebuker' from the chest to the head and renames it Logos
Peterson traces the historical dismantling of the thūmos's archetypal grammar to Plato's tripartite soul, arguing that philosophical rationalism suppressed a prior, grammatically embedded mode of soul.

Inner figures such as shadow, anima and animus would be archetypal processes having sources in the right hemisphere
Samuels surveys neurological attempts to localize archetypal grammar in cerebral architecture, noting that right-hemisphere and limbic structures have been proposed as the biological seat of archetypal patterning.

Jung was to conceive of the archetype as no mere mental abstraction but as a dynamic entity, a living organism, endowed with generative force… not an arid, intellectual concept, but a living, empirical entity, charged not only with meaningfulness but also with feeling
Papadopoulos introduces the tension within archetypal grammar between formalist and dynamist readings, stressing that for Jung the formal schema is inseparable from numinous, affective charge.
