Gestural Expression

Merleau-Ponty's Sorbonne-period doctrine (chapter 8 of *Child Psychology and Pedagogy*, 1951–52) of the body as the medium of intersubjectivity through gesture: "the body inhabited by meaning"; "to perceive the other is to decipher a language"; "no exterior coordination, but a reciprocal animation of one by the other." Per the candidate claim claims#gestural-expression-bridges-php-to-prose-of-world, gestural expression is the genealogical bridge between PhP's "expression" (1945) and the *Prose of the World*'s "indirect language" (drafted 1951–52). The closely related lived-gestural-expression page captures the same doctrine with somewhat broader scope; this page focuses on the gestural mechanism as such.

Key Points

The signature formulations (CPP ch. 8): "the body inhabited by meaning"; "to perceive the other is to decipher a language"; "no exterior coordination, but a reciprocal animation of one by the other."
The PhP→Prose of the World bridge: per the candidate claim claims#gestural-expression-bridges-php-to-prose-of-world, the chapter 8 doctrine is the bridge between PhP's "expression" (1945) and Prose of the World's "indirect language" (drafted 1951–52). The Sorbonne lectures document the maturation in real time.
Four modes of expression (per the related page lived-gestural-expression): mythic-ritual / dramatic / lived / linguistic. Gestural expression is the lived mode that connects body-expression to language-expression.
Style as connector to language: gestural style is what carries over from bodily expression into linguistic expression — the operation does not change in character, only in register.

What the Concept Does

The concept gives MP a developmental-genealogical mechanism for the otherwise-difficult transition from PhP's phenomenology of perception (which has expression but underdeveloped) to the late ontology (where indirect language and the flesh of language are central). Gestural expression is the middle term across the 1945–1952 period: it shows how the body that PhP described already speaks in a way that anticipates Prose of the World's language philosophy. Without this middle term, MP's trajectory looks discontinuous; with it, the development is incremental.

Open Questions

Whether the chapter 8 doctrine names a distinct concept or restates PhP's body-expression in pedagogical register. The candidate claim treats it as substantively new; counterpressure (PhP already says much of this) is recorded in the claim entry.
Relation to primordial-expression: developmental-genealogical anchor distinct from the Eye and Mind register, per the candidate claim's payoff statement.
Why the wiki has both gestural-expression and lived-gestural-expression — whether a merge is warranted.
