The Greek middle voice occupies a distinctive and productive place within the depth-psychology corpus, primarily through Rutger Allan's sustained linguistic analysis, which treats it as a polysemous network category rather than a simple grammatical opposition. Allan's monograph demonstrates that the middle voice in Ancient Greek encodes a fundamental semantic principle — subject-affectedness — whereby the grammatical subject functions simultaneously as both Initiator and Endpoint of the event. This characterization, indebted to Kemmer's typological work and Langacker's cognitive grammar, organizes a diverse range of usage types — from passive and spontaneous process middles to reciprocal, mental process, body motion, and indirect reflexive middles — into a coherent semantic map. The central tension in the corpus lies between reductive accounts (valence reduction, simple reflexivity) and the network-polysemy model Allan defends, which resists collapsing the middle's meanings into a single scalar dimension. A secondary tension concerns the historical expansion of the passive aorist at the expense of the sigmatic middle aorist, tracing morphological change through the semantic network's connected regions. Peterson's adjacent work on the 'abolished middle' gestures toward a broader cultural-psychological resonance of the grammatical category, suggesting that the soul's tripartite structure was itself implicated in debates over middle-voice ontology. The term thus bridges technical linguistics and depth-psychological reflection on agency, interiority, and the dissolution of subject-object duality.
The middle voice in Ancient Greek can be said to code that the subject is the Endpoint of the event.
Allan's general conclusion formulates the unifying semantic definition of the Greek middle voice as the grammatical encoding of subject-as-Endpoint, integrating eleven distinct middle uses into a single polysemous network.

the middle voice is seen as a polysemous network of interrelated meanings. The abstract schema, embodying the semantic commonality of all middle meanings, can be characterized as affectedness of the subject.
Allan establishes the cognitive-linguistic framework for the middle voice as a complex network category whose unifying abstract schema is subject-affectedness, the foundation for the entire polysemy analysis.

the middle voice expresses that the subject is conceptualized as both the Initiator and the Endpoint.
Allan articulates the macro-role formulation of the middle voice, drawing on Kemmer's typology to define the middle as a construction in which the subject occupies both causal origin and terminal positions within the event chain.

the middle voice can be defined as a marked coding of a departure from the prototypical transitive. Contrary to the prototypical transitive, the subject, in some way or other, undergoes
Allan defines the middle voice negatively against the norm of prototypical transitivity, framing it as a marked grammatical departure in which the subject's affectedness distinguishes it structurally from the active voice.

There have been many attempts to capture the essence of the semantics of the Greek middle voice. This is not an easy task if one considers the diversity of middle usages such as passive, intransitive, direct reflexive and indirect reflexive.
Allan surveys the longstanding difficulty of defining a common semantic core for the Greek middle voice, situating his own polysemy approach against the tradition of grammatical scholarship from Kühner-Gerth onward.

all verbs inherently involve subject-affectedness. This inherent subject-affectedness motivates the presence of the (semantically redundant) middle inflection.
Allan explains the coexistence of active and middle inflections in poetry by demonstrating that inherent lexical subject-affectedness can make the middle morpheme semantically redundant while still motivating its use.

The middle ending makes this inherent element conceptually more salient, whereas the active ending - being neutral as to subject-affectedness - does not contribute to the meaning of the verb.
Allan distinguishes the functional contribution of middle versus active endings, arguing that the middle voice foregrounds an already-present semantic feature of subject-affectedness rather than introducing a wholly new meaning.

mental states are typically temporary. As such, mental states are different from states that have a more permanent character such as 'be king', 'be small', 'be red'.
Allan characterizes the mental process middle as encoding transient subject-internal states, distinguishing this middle type from both permanent statives and fully agentive processes.

the Greek middle voice diverges from the reflexive systems as they are found in modern European languages. In these languages, the direct reflexive type has a more central status within the category.
Allan argues that the direct reflexive, central to modern European reflexive systems, is comparatively peripheral in Greek, where the mental process middle holds prototype status within the network.

In the course of the history of the Greek language, a gradual expansion of the passive aorist form can be observed. This expansion takes place mainly at the cost of the sigmatic middle aorist.
Allan traces the diachronic displacement of the sigmatic middle aorist by the passive aorist form, using the historical expansion as evidence for the connectivity of semantic regions within the middle voice network.

The subjects of the passive aorist forms, on the other hand, are more patient-like.
Allan demonstrates that aorist morphology correlates with semantic role: sigmatic middle aorists pattern with volitional subjects while passive aorist forms align with more patient-like subjects, confirming the network's semantic organization.

The two reciprocal types mentioned above (with and without dative complement) involve a different conceptualization of the event.
Allan analyzes reciprocal middle constructions to show how subject-configuration and complement structure encode distinct conceptualizations of symmetrical versus foregrounded-participant events.

it is safe to conclude that the middle voice is structurally (in particular, phonologically) marked compared to the active.
Allan establishes the morphological markedness of the Greek middle voice over the active through systematic comparison of phonological heaviness across the paradigm, grounding the semantic analysis in formal evidence.

the structure of the semantic network of the middle voice. In several respects, my classification will be finer-grained than Rijksbaron's presented above. This refinement is primarily supported by typological evidence.
Allan positions his classification of middle uses as more granular than prior accounts, grounding refinements in cross-linguistic typological evidence from Kemmer and Croft alongside morphological data from the aorist stem.

for students of the Greek middle voice the primary importance of Kemmer's description of the spread of the reflexive marker from one use to another lies elsewhere.
Allan explains how Kemmer's diachronic methodology — tracing form-spread between related meanings — is methodologically foundational for understanding the Greek middle voice's semantic network and aorist morphological distribution.

Apart from (12), the logophoric middle, and the facilitative middle, each of the enumerated middle uses seems to be instantiated in Ancient Greek.
Allan maps Kemmer's cross-linguistic typology of middle uses onto Ancient Greek, confirming the broad applicability of the typological framework while noting the absence of logophoric and facilitative sub-types in Greek.

The mental process middle is related to the passive middle. In both types, the subject passively undergoes the event. The difference between the two middle types relates to whether or not the event is initiated by an external agent.
Allan delineates the semantic boundary between mental process and passive middles, identifying external agentive initiation as the decisive distinguishing criterion within the network.

The higher a member's frequency of occurrence, the higher its cognitive salience. The second criterion relates to the centrality of the member within the network.
Allan applies prototype theory to determine which middle use is most central, using token-frequency and network-centrality as dual criteria for establishing the cognitive prototype of the middle voice category.

The subject-affectedness, therefore, must be an inherent property of the lexical meaning of the verb root. The unmarked active voice can be used since the subject-affectedness is already present in the context.
Allan argues that when subject-affectedness is lexically inherent to the verb root, the active voice can substitute for the middle without semantic loss, clarifying the relationship between grammatical voice and lexical meaning.

aorist morphology suggests that uniting the oppositional middles and the media tantum designating mental processes is justified since both always have a passive aorist form, and never a sigmatic middle aorist.
Allan uses aorist morphological distribution to validate the semantic classification of media tantum, demonstrating that morphological patterning mirrors the network's semantic groupings.

beneath the political maneuvering lay a theological question with deep grammatical roots: What is the structure of the human soul?
Peterson invokes the notion of a grammatically-resonant 'abolished middle' in connection with the Fourth Council of Constantinople's canonical exclusion of the tripartite soul, situating the Greek grammatical category within a depth-psychological and theological genealogy.

Is there a semantic element common to these usage types? If so, how should it be defined? Assuming that the various middle uses constitute a polysemous structure: in what way are the middle uses related to one another?
