Middle Voice and Patientive Grammar

Allan’s Middle Voice in Ancient Greek and Peterson’s retrieval of the Homeric soul converge on a single structural claim: the Greek language carried, in its verbal morphology and lexicon, a third grammatical position the Indo-European inheritance largely lost. That position is the patientive — the subject as site of an event it does not author.

Allan reconstructs the ancient grammarians’ precise vocabulary. Πάθος and παθητική are not synonyms for the morphological passive but “semantic terms, designating events in which the subject undergoes the action” (Allan 2003, p. 17, citing Apollonius Dyscolus). Apollonius coins the subclass αὐτοπάθεια — “auto-passivity” — for verbs whose patient-status is carried in the lexeme itself: πάσχω, νοσῶ, ὀφθαλμιῶ, θνῄσκω. These behave actively in form but undergo semantically. The ancient grammarians already saw what modern grammarians had to rediscover.

Lyons’ definition, which Allan adopts, names the Middle Voice’s broader semantic territory: “subject-affectedness” in the broad sense (Allan 2003, p. 18, after Lyons via Barber 1975). The Middle subsumes “all cases in which the subject is affected by the action” — passive, reflexive, reciprocal, and the productive class of verba affectuum (verbs of affection) such as αἴδομαι (revere), σέβομαι (feel awe) (Allan 2003, p. 17, after Schwyzer).

Peterson reads this grammar back onto the Homeric soul. The thumos is the destination of the Homeric emotion-verbs; the hero does not make himself joyful but receives joy into a chest that has been engineered to contain it (Peterson 2025; Caswell 1990, Appendix). The Middle Voice and the patientive lexeme are two faces of one fact: archaic Greek inherits a self for whom being-affected is the primary mode of being a self at all.
