From Hinge to Chiasm: What Changes in the Transition?

The Evidence

The I&P extraction note identifies "hinge" (charnière, gond, pivot) as a HUB-weight recurring motif across the 1954–55 courses, appearing at 3, [22], 127, 179, 215 verso. Institution "exists between others and myself, between me and myself, like a hinge" (Course Summary). The figure names the relational structure through which MP articulates institution's non-reducibility to either pole.

The 1953 course introduces "encroachment" (empiètement) as a proto-chiasmic figure: "feedback from the end of the process on the beginning" and "encroachment of the beginning on the rest" 74.

By 1960–61, the figure is the "chiasm" (chiasme) — drawn from rhetoric (the ABBA crossing figure) and anatomy (the crossing of the optic nerves). The chiasm names the "intertwining" of sensing and sensed, seer and visible, and is called "the ultimate truth" (V&I Ch 4, p. 155).

The Structural Identity

A hinge has two leaves that open around a common pivot. The chiasm's "two leaves" of the body — sensing and sensed — "have never been apart" (V&I November 1960 working note). Both figures describe: (1) two sides that are aspects of one structure, not pre-existing parts joined together; (2) a turning-point that is itself invisible — the hinge-pin, the crossing; (3) communication between the sides that depends on the turning-point rather than on external mediation.

The proposed genealogy: hinge (1954–55) → encroachment (1953, already tracked) → chiasm (1960–61).

What Changes

Despite the structural identity, the shift from hinge to chiasm may signal three changes:

  1. From mechanical to organic figure. A hinge is an artifact — a hardware metaphor. A chiasm (whether rhetorical or anatomical) is a natural crossing. The shift may reflect MP's turn from institutional phenomenology (which still works with artifacts, techniques, cultural objects) to the ontology of flesh (which works with being's own self-organization).

  2. From relational to reflexive. The hinge mediates between two distinct poles (self/other, self/past). The chiasm describes a single entity's self-relation (the body touching itself, the visible folding back on the seer). The hinge connects; the chiasm intertwines.

  3. From psychological to ontological register. The 1954–55 hinge operates in the register of personal history, intersubjectivity, and psychoanalysis. The 1960–61 chiasm operates in the register of Being, flesh, and the visible/invisible. The same structure is lifted from the human sciences to ontology.

Open

  • Does MP use "hinge" in the V&I working notes or the 1959–61 courses? If so, the two figures coexist and the replacement is not complete.
  • Is there a middle term in 1956–58? The Nature courses (1956–60) might contain transitional uses.
  • Chouraqui 2016 uses charnière in his own analysis of MP's "intra-ontology." Does this suggest the hinge figure remained philosophically productive even after the chiasm appeared?
